Description

This application claims priority and benefits for the United States Patent Application 60/438986, filed January 10, 2003, and the application 60/482519, filed June 26, 2003, both of which are incorporated herein by reference. links.

FIELD OF THE INVENTION

The present invention relates generally to a sanitization system, as well as to individual system components.

FIELD OF THE INVENTION

Microbial infection is the main cause of the disease. Bacteria and viruses can be found in water, on food, or on surfaces. Currently, there are many technologies suitable for eliminating and / or reducing the growth of microbes. However, the effectiveness of each particular method depends on the substance being processed, and on the type of existing microbes. In addition, reagents have harmful effects on human health, both on their own and due to by-products produced during the sanitation process.

Harsh chemicals that can clean surfaces may have persistent odors or corrosive effects on the user's skin, and, of course, may not be acceptable for food sanitization.

U.S. Patent No. 4,173,051 to Raid discloses a vegetable washer that uses blades to mix and peel vegetables, but does not reduce bacteria.

US Patent No. 5,927,304 to Wang discloses a food washer that uses vibration to remove the earth and ultraviolet radiation to kill bacteria.

There is a need for sanitization of a system in which sanitization or disinfection with multiple applications is possible. There is also a need for a consumer-friendly method of sanitizing and disinfecting water, which is carried out economically, and an autonomous unit. In the future, foods, vegetables, plants and surfaces that many people regularly come into contact with may be more suitable for consumption thanks to an effective sanitation system that does not use hazardous chemicals.

The term sanitizing, as used herein, refers to the removal of at least a portion of undesirable components from a surface, such as a liquid, such as water, or from a solid surface, such as an object such as a food product. The term cleaning, when used in relation to a water or other surface, is used here synonymously with the term sanitization. The term disinfection, when used in this document, refers to a high level of sanitization of both liquid and solid surfaces. At the disinfection stage, the vast majority of living bacteria, viruses and / or other "infectious" agents are removed from the liquid or solid. The term disinfection, however, is not used synonymously with the term sterilization, which is the highest form of sanitization, involving a process more advanced than disinfection.

Water ozonation

Ozone O ₃ is a strong oxidizing agent and is widely used as a disinfectant for food and water. Examples are found in US Pat. No. 6,171,625 to Denver et al., US Pat. No. 6,200,618 to Smith and others, and US Pat. No. 6,485,769 to Audi and others. However, these systems are large industrial complexes, and not can prevent re-contamination of food before shipping.

US Pat. No. 6,391,191 to Conrad discloses a home water treatment apparatus that uses ozone to disinfect water.

U.S. Patent No. 5,460,705 to Murphy et al., U.S. Patent No. 577,0003 to Murphy and others, and U.S. Patent No. 5,989,407 to Andrews and others disclose devices capable of generating ozone. Ozone obtained in this way can be used for ozonation of water.

Venturi Vortex Tube Devices

Prior art documents regarding the advantage of defining a venturi vortex tube arrangement include US Pat. No. 4,123,800 issued to Mazzei, US Pat. No. 4,931,225 issued to Cheng, US Pat. No. 5,061,406 issued to Cheng, US Pat. U.S. Patent No. 5,863,128 to Matstsi, U.S. Patent No. 5,880,378 to Behring and U.S. Patent No. 5,893,641 to Garcia.

The dispersion of one flow in another is an important feature of a wide variety of designs. For example, gases are dispersed in liquids to carry out numerous gas dissolution reactions, gas-liquid interactions, and gas purification from dissolved additives. Gases also mix with each other. Liquids are also dispersed in other liquids to dilute or carry out liquid-liquid reactions.

Many devices have been developed to disperse one additional stream stream into another main stream. The purpose of such devices is to bring into contact one stream in another in a proportional quantity. In addition to this dosage stream, it may be desirable to have an additional stream well dissolved and distributed in the main stream. If the additional flows are gas, then the dissolution efficiency depends on the size and nature of the movement of the bubbles. The vigorous movement of small bubbles will accelerate the dissolution of the gas. Vigorous movement will also facilitate fluid mixing.

For example, U.S. Patent No. 4,931,225 issued to Cheng discloses a method and apparatus for dispersing gas in a liquid. Gas is blown into the liquid upstream of the venturi. After that, the gas-liquid mixture flowing through the venturi is accelerated to supersonic speed, and then slows down to infrasonic speed. The resulting shock wave destroys and scatters gas bubbles in the liquid.

US Pat. No. 5,061,406 to Cheng discloses a method for dispersing gas in a liquid using an adjustable conical mixer to control the flow of a gas / liquid mixture to a venturi device. Using a conical mixer in the venturi creates an annular hole and controls the size of the hole. At supersonic speeds, gas is blown upstream of the venturi. The gas / liquid mixture is accelerated to supersonic speed, and subsequently slowed down to infrasonic speed. The resulting shock wave scatters gas in a liquid.

US Pat. No. 5,302,325 to Cheng discloses a method for dispersing gas in a liquid using a conical mixer. The mixer is located inside a cylindrical pipe, which leads to an annular flow. Gas at supersonic speed is blown into the mixer. As the gas / liquid mixture passes through the annular gap, it accelerates to supersonic speed and slows down to infrasonic speed, resulting in a shock wave scattering the gas. Annular flow is the reason that a large fraction of the flow is supersonic.

The problem with these devices is that during gas dispersion they require additional energy in order to blow gas.

The venturi device is based on an injector-mixer, which is also known. U.S. Patent No. 4,123,800 to Mazzea discloses a venturi device comprising a tapering portion, a neck portion, and an expanding portion. Many channels are annularly grouped around the inner part of the neck section and are connected to the annular chamber around the neck section.

U.S. Patent No. 5,863,128 to Mazzei discloses a Venturi-type injector / mixer with a tapered section, a neck section, and an expanding section. Numerous swirling guides in the tapering part create whirlpools in the outer part of the stream, and numerous straight guiding devices in the expanding part eliminate some whirlpools for improved mixing.

US Pat. No. 5,893,641 to Garcia discloses a controllable venturi injector including a converging portion, a neck portion and an expanding portion. The second additional flow is blown through a plurality of channels located radially in the groove near the exit of the expanding part. The second stream is blown perpendicular to the main stream.

Gas-liquid separator

The presence of entrained gases in liquids is common, and in most cases this is not very desirable. These cases relate to boiler systems and hydraulic systems, where the included gases can cause interference or damage to parts. There are also systems in which gases are specially introduced into liquids. These systems include cases where nitrogen is added to the liquid to displace oxygen. In these systems, it is necessary that both the entrained gas and the displaced gas are then removed, and thus the degassing of the liquid is ensured.

Another application of a gas-liquid separator is to remove undissolved oxygen or ozone after these gases have been entrained in water. Ozone is used to disinfect water. Water is capable of dissolving a certain amount of ozone, but the process of enhanced ozonation leads to a certain amount of undissolved gaseous ozone. Undissolved ozone is dangerous to release directly into the atmosphere. The method requires the removal and processing of undissolved gaseous ozone formed as a result of such a process.

Sensors of redox potential of redox potential.

Sensors of the redox process of redox potential are known from the prior art, for example, from US Patent N 5218304 issued to Kinlen and others, and from Application N 2003/0112012 to US Patent Mosley et al.

US Pat. No. 5,218,304 to Kinlen et al. Describes a sensor that can be immersed in a stream to determine the pH and ORP of a stream. The sensor described uses a silver / silver chloride reference electrode and an ORP measuring electrode made of a noble metal such as gold, or preferably platinum. The disadvantages of using such a reference electrode are the cost, taking into account suitability factors in the manufacture of household appliances for the consumer.

U.S. Patent Application 2003/0112012 Mosley et al. Describes a galvanic probe including a sensor electrode and a reference electrode. The probe uses a reference electrode made of a noble metal, or antimony or bismuth, or their oxides or hydroxides, and an electrode for measuring the redox potential of the redox potential of zinc or magnesium, or their oxides or hydroxides. The disadvantage of using such a measuring electrode is the cost, taking into account suitability factors in the manufacture of household appliances for the consumer.

A popular household device for filtering water has the form of a jug with through pores for the flow of water. Usually unfiltered water is poured into the top bowl to the top of the device. Under gravity, water seeps through the filter medium, usually consisting of granular activated carbon, located between the upper bowl and the reservoir tank. Filtered water is then dispensed from the collector tank for drinking. For the general public, a water filtration system based on gravity control is most affordable. However, although purified water is obtained in this way, the gravity-based filtration method does not allow disinfectant gases, such as ozone, to be included in the purified water. Subsequently, the purified water thus obtained can have a small disinfecting effect on the surface with which it comes in contact differently than by mobilizing or washing off bacteria, viruses or other undesirable components.

It is not possible to filter out or destroy the smallest organisms or microbes with a device that works like end-to-end pores. To facilitate the flow of water, it is necessary that the filter medium through which water is passed has a porous nature. Due to this need, such devices cannot purify or disinfect water as effectively as other water treatment devices. In part, this inefficiency is due to the lack of additional cleaning steps and the hope only of the filter itself. In addition, the filter medium or cartridge used in this pitcher-like structure, which works due to the presence of through pores, usually extends into the interior of the reservoir reservoir in contact with the filtered water. In some cases, this can be unfavorable if other methods of cleaning or sanitizing the liquid are not used. The porosity of the filter medium can even contribute to the seepage, accumulation and growth of microorganisms. Thus, there is an increased likelihood of contamination of filtered water when the filter medium enters the inside of the reservoir tank.

US Pat. No. 5,222,078 to Polyaski et al. Describes a pitcher-shaped pressureless filter with through pores.

US Pat. No. 6,103,114, issued to Tanner et al., Discloses a device that attempts to avoid contamination by optimizing the design of the neck, the porous region, and the seal between the inner tank and the filtered water tank. However, the filter in this project is still buried inside the filtered water tank and is a potential source of contamination. US Patent No. 6,290,848, issued to Tanner et al., Discloses a porous purification filter to remove 99.95% of all 3-4 micrometer cryptosporidia and other simple cysts. US Patent No. 6,103,114, issued to Tanner et al., Describes a decanter-shaped filter device with a protrusion above the edge to prevent the untreated water from mixing with the treated water during cleaning.

US Pat. No. 6,391,191, issued to Conrad, discloses a household water treatment equipment with a pump that uses ozone and a carbon block filter to disinfect water.

US Patent No. 6,238,552, issued to Shannon, discloses a universal insert for a water purifier with a filter at the top and bottom and a guide device for sliding the liner inside the jug.

U.S. Patent Nos. 4,969,996 and Nos. 4,306,971 to Hankammer disclose a column-shaped filter apparatus elongated inside the collector reservoir. The implementation of this project could potentially contribute to the emergence of a source of pollution.

U.S. Patent No. 6405875, issued to Cutler, describes a decanter-shaped filter apparatus with ion-exchange resin and carbon granules, which removes 99.95% 3-4 micrometer particles. However, this device is buried in a tank with filtered water and thus may be subject to contamination.

All links marked here are included in this link.

Thus, there is a need for improvements in purification devices that allow convenient access to purified, sanitized or disinfected water. There is also a need for a system that uses many technologies to achieve a high level of sanitation. In the future, a system is desirable that allows combining liquid purification with other types of sanitization if items, food products or surfaces are subject to sanitization with the liquid obtained in this way.

In addition, there is also a need for an effective sanitation system capable of producing a liquid that disinfects food products, objects or surfaces.

DETAILED DESCRIPTION

In General, the present invention provides the creation of a sanitation system and individual components of such a system. The system allows the sanitization of liquids, which can then be used to disinfect a wide variety of items, such as food products, or other surfaces. Sanitization of the item can be performed inside the container in this system, or the container containing the disinfected liquid can be moved from the base to another place for use.

The present invention describes a reusable liquid sanitization system consisting of a base and at least one transportable container.

This document, in accordance with the invention, describes a sanitization system producing ozonated liquid. An embodiment of the invention includes a pump for circulating fluid through the system; double check valve for contact with a source of fluid to be ozonized, allowing at the same time to let flow into and out of the system; an ozone generator for producing ozone intended for incorporation into the liquid; and a venturi vortex tube for introducing ozone into the liquid. A venturi vortex tube, including an inner chamber with a central longitudinal axis, inside which the liquid enters tangentially to the longitudinal axis, while the inner chamber of the vortex tube has an expanded initial section, a narrowed neck section with ozone inlet openings formed in it, and an expanded exhaust section for a mixed stream from which ozonated liquid flows. The ozone generator is connected by a fluid stream to a venturi vortex tube to deliver ozone to the inlets.

It is possible, as an option, that the liquid source is preferably water contained within a container in fluid communication with the pump. The container may contain a double check valve in its bottom, and fluid circulates into and out of the container through the double check valve. It is also possible that the container is removable, but this is not necessary. As an option, multiple transportable containers having double check valves located in them can be used interchangeably.

In this embodiment, a pump, a double check valve, an ozone generator and a venturi vortex tube can be placed together inside the base.

Additional optional system components may be added. For example, the system may include an ozone generator, preferably having an ozone corona discharge generator. The ozone corona discharge generator produces ozone through the use of high-frequency and / or high-voltage power. In this case, the ozone corona discharge generator includes an ozone generation chamber having open ends, a high voltage electrode at each of the open ends; insulating end plugs located on the cable ends of the chamber, plugs having openings for the passage of gas made in them in the tangential direction to the chamber, passing the vortex flow through the generator; and a ground electrode comprising a metal foil deposited on a dielectric material.

The system may, in addition, include an ORP redox potential sensor in fluid communication with the system for detecting ozone levels in the fluid.

The ozone destructor can be included in the system downstream than the gas-liquid separator, and have a fluid communication with it, for the decomposition of undissolved ozone gas leaving the gas-liquid separator.

The next possible component is a gas-liquid separator located downstream of the Venturi vortex tube to separate insoluble gases from ozonated liquid. In this gas-liquid separator, undissolved ozone gas is separated by using centrifugal force. As an example of such an option, the separator may include: an inlet through which a gas-liquid mixture exiting the vortex venturi enters it under pressure; channel following the entrance; means for creating a vortex flow of a gas-liquid mixture in the channel under pressure to create a centrifugal force to move undissolved ozone gas to the center of the channel, and liquid to the periphery of the channel; a groove placed around the inner side of the channel through which part of the fluid is discharged; an annular chamber communicating with a groove through which fluid passes; and a valve opening for discharging gas through which gas exits the channel.

Alternatively, the gas-liquid separator may include a float for interacting with the liquid in the chamber to close the gas outlet when the liquid level is high.

The system in accordance with the invention may include a capacitive coupled detector operated by high-frequency and high-voltage power to check the power supply to the ozone generator. A capacitive coupled detector may include: a first wire conducting a high voltage and / or high frequency current leading to an ozone generator; the second current conductor, as close as possible to the high voltage and frequency current conductor, leading to the ozone generator, generating, due to the maximum proximity of the first and second wires, a capacitance; and a detector circuit connected to a second wire for determining capacitance, including a microprocessor, and a standby multivibrator, to check the power supply to the ozone generator. The detector circuit is powered by an external energy source or by an electric capacitance.

The system may further include a redox sensor, including: a reference electrode made of silver or plated with silver; ORP probe made of platinum, plated galvanically with gold, or plated with gold; ORP sensor in liquid contact with the water stream; and a constantly working monitoring sensor that monitors process time.

An embodiment of the invention also includes a venturi vortex tube for introducing gas into a liquid, including a cylindrical body with an internal chamber, a liquid inlet, a gas inlet and an outlet for a gas-liquid mixture, the inner chamber having a helical channel between the liquid inlet and the gas-liquid outlet mixture, and includes an expanded initial section, decreasing in diameter before transitioning to a narrowed neck section, mainly of a cylindrical configuration, and an expanded output section, expanding with the growth in diameter relative to the narrowed section, and the inlet for the liquid is located tangentially to the entrance to the inner chamber to create a vortex effect in the fluid flowing through it; and wherein the gas inlet is inserted into the inner chamber through inlet openings formed in the constricted section.

A venturi vortex tube may have one or more guide devices located in the inner chamber on the surface of the expanded outlet section.

An additional embodiment of the invention is a sanitization system for producing ozonated liquid, comprising a main pump for circulating liquid through the system; liquid container; double check valve inside the fluid container to ensure that fluid flows into and out of the system; an ozone generator for generating ozone embedded in the liquid; a sprayer located in the container and connected by a fluid stream with a double check valve for injecting ozone from the ozone generator into the liquid; and an ozone pump in fluid communication with an ozone generator to remove ozone from the sprayer.

The system according to the invention may further include a filtering unit operating according to the through-pore principle, described in more detail below.

In accordance with an embodiment of the invention, the base comprises a pump, a Venturi vortex tube, a centrifugal degasser, an ozone generator, an ozone destructor, an ORP redox potential sensor, corresponding connections and electronic circuits. Different containers can be delivered to the base unit, depending on which process is needed. A jug for disinfecting water, a filter bowl and a strainer for sanitizing vegetables, or a sprinkler or other container for storing ozonated water for disinfecting surfaces may be included. The containers contain a double check valve which contacts the base and in which a single connection point is provided.

In accordance with one embodiment of the invention, the base can automatically identify the type of container located on it, and thus run the corresponding program. Alternately, the user can select the appropriate program.

Individually, the components of this system are described in detail below, along with a further description of the sanitation system. The three components that can be used in conjunction with this system include a double check valve, a venturi vortex tube, which here can be called simply a “venturi tube”, and an ozone generator. Each of these components will be described separately below. Optionally, optional components can be used, such as a centrifugal gas-liquid separator with an integrated gas release valve, hereinafter referred to as a “degasser", an ozone destructor, a redox sensor, or another component capable of disinfecting a liquid.

Double check valve

The double check valve device according to the invention allows controlling flows, and in particular, but not exhaustively, controlling flows inside and outside the container. The container can be permanently installed or removed, and the flow inside and outside the container can occur simultaneously or sequentially.

Check valves have various applications when it is necessary to be limited to one direction. Examples include options for filling and emptying tanks and controlling fluid flow, for example, in a pipeline. However, if the flow requires two directions at the same time, for example, flow into and out of the tank, two separate check valves are required, and thus two openings in the tank are needed.

According to an embodiment of the invention, a double check valve is provided allowing two independent flows passing simultaneously or independently through the same check valve assembly.

The double check valve allows two separate and independent flows passing through a single check valve assembly. In addition, the device, as an option, may have a plug capable of deflecting the stream from one or both of the independent streams in order to enhance the separation of the stream until a mixture of liquids from each stream is achieved. When means for deflecting the flow, located below the plugs, are installed, they can transmit rotational motion to the fluid flow flowing past them. The check valve device also allows you to remove the container from the base and to prevent leakage of liquid from both the base and the container when the container is removed. The two valve stems embedded in the check valve device can be controlled independently or jointly.

The double check valve may comprise first and second check valves, which are independently controlled, and wherein the first valve, for example, is inserted inside the second. Thus, two independent jets of fluid flow are created, with one flow flowing through the second valve stem and around the first, and the second flow flowing around the second valve stem.

In accordance with one embodiment of the invention, the double check valve device has an outer casing having an inlet and outlet with first and second valve stems contained in the outer casing. The outlet in the outer casing is a valve seat to the second valve stem. The first valve stem is smaller than the second valve stem and is contained within the second valve stem and is operated along a common axis. The second valve stem has a cylindrical channel passing through it, and which contains the first valve stem, and also has a valve seat for the first valve stem. The jets of fluid can thus pass around the first valve stem and through the second. The first and second valve stems are surrounded by individual springs. These springs act on the valve stems to bring them into contact with the respective valve seats. The first and second valve rods can operate both independently of each other, and together.

When the valves are open, two independent fluid flows are created — one flow around the second valve stem and through the outlet of the outer casing, and the other through the second valve stem and around the first valve stem.

The double check valve device according to this embodiment of the invention is an integral part of the wall of the liquid container, both permanently installed and mobile, and requires the control of the input and / or output stream. Various types of containers used in conjunction with the invention are described elsewhere. Preferably, the valve is an integral part of the bottom wall of the bottom of the container.

The first valve stem may optionally have a cylindrical channel, partially forming flows passing through it when the first valve stem is removed from the valve seat.

The outer housing may optionally have one or two protrusions that are mounted radially and surround the outlet and the first and second valve rods. These protrusions may take the form of mounting bosses or flow deflectors. In the case where the protrusions are flow deflectors, they can be arranged in such a way as to impart rotational motion to the flow flowing around the second valve stem. In the case where the protrusions are fixing bosses, such fixing bosses are used to attach a removable plug to the outer casing over the first and second valve seats. In such an embodiment of the invention, the plug may comprise flow deflectors, a centrally located channel and a valve seat.

The plug can be attached to the mounting bosses, in which case the flow deflectors located in the plug create ducts through which the flow will flow. Flow diverters can impart a rotational movement to the jet. When the first and second valve stems release the second valve seat opposite the valve seat in the plug, the first valve seat extends into the passage through the center of the plug. Thus, the two ducts are effectively separated. One stream flows around the second valve stem, under the plug and through flow deflectors, and the other flows through the channel in the center of the plug and around the first valve stem.

1 is an isometric view of an image of a double check valve block 100. The double check valve kit has a plug 102 located on a surface covering the interior of the container in which the kit is placed. The cap is optional, but when it is, it serves to facilitate mixing inside the container. Below the plug are fan-shaped blades 104, which provide the movement of water that passes near the blades. The first valve passes along the central axis of the kit, collecting jets in a downward flow. The first valve has an inlet (shown in FIGS. 2 and 3) and an outlet 106. The second valve is a ring around the first valve and allows the return of ascending fluids. The inlet 108 of the second valve is located at the lower end of the kit, and the outlet of the second valve is located at the upper end of the kit, below the plug, as shown in FIGS. 2 and 3.

Figure 2 is a top view of a double check valve kit shown in Figure 1, with the plug removed. This view is more clearly illustrated by fan-shaped blades 104 mounted below the plug. The inlet opening 202 of the first valve and the outlet 204 of the second valve are visible when the plug is removed.

When there is no plug, the double non-return valve retains the same function, but to a lesser extent facilitates mixing of the jets in the container, compared with the option in which there is a plug.

FIG. 3 is a sectional view of a double check valve kit 100. A first check valve stem 302 is shown embedded in the inlet 202 of the first check valve. The second check valve stem 304 is shown outside the inlet 202 of the first check valve. An o-ring of the first valve stem 306 is located around the stem of the first non-return valve. A second valve stem O-ring 308 surrounds the second valve stem. The second valve stem spring 310 is shown together with the first valve stem spring 312. An O-ring O-ring 314 is present on the outer surface of the double check valve kit to provide a tight and fluid connection between the kit and the mating element.

FIG. 4 is an isometric view of an image of a double check valve kit 100 of FIG. 1 and a mating member 402. The mating member includes a flow reservoir flowing from the first and second check valve. A central pipe 404 allows flow to flow out of the first check valve, while a return pipe 406 allows flow to flow into the second check valve. In this embodiment, the double check valve set and the mating element are fastened together in a removable state, and the joint between these components is sealed by the outer ring seal shown in FIG. 3.

FIG. 5 is a plan view of a double check valve kit and a mating member as shown in FIG. 4. It is shown that the cap 102 has connection points 502 by which the cap is attached to fan-shaped blades. The inlet 202 of the first valve and the outlet 204 of the second valve are shown.

FIG. 6 is a sectional view of the double check valve kit and the mating component of FIG. 4 taken along line AA of FIG. 5. Shown is the first valve stem 302, the second valve stem 304, the first valve stem O-ring 306, the second valve stem O-ring 308, the second valve stem spring 310, the outer housing O-rings 314, and the first valve stem spring 312. Additionally shown is an o-ring 602 of the Central channel, which provides fastening of the set of double check valve and the mating element. As can be seen in this section, the jet flowing into the first check valve flows through the central pipe 404 for further processing, while the stream flows through the return pipe 406 to the central reservoir 604, awaiting return through the second check valve. When the second check valve kit is disconnected from the mating member, flow cannot flow upward through the second check valve. Only when the double check valve kit is bonded to the mating element does fluid flow out of the central reservoir. This is a favorable condition for fluid retention if the container is not in its place at the base.

Fig.7 is a set of double check valve and the associated element of Fig.4. A plug 102, a central pipe 404, a reverse flow pipe 406, and a central reservoir 604 are shown. In this embodiment, the reverse flow pipe enters from the angular offset position into the central reservoir, which facilitates mixing of the liquid in the central reservoir. An upper portion 702 of the mating element has been identified, showing the area where the double check valve contacts the mating component.

Venturi vortex device.

A venturi vortex device is an aspect of the present invention that relates to the introduction and mixing of liquids. In particular, this aspect of the invention allows the mixing of liquids based on the Venturi principle, and introduces a vortex component for accelerated entry of the main stream into the device before mixing with the additional stream. Once introduced into the system of the present invention, a Venturi vortex device may include an additional stream, such as ozone, in a main stream, such as water, so as to obtain ozonated water used in further sanitation processes. Ozonated water thus obtained is also itself a disinfected product. The device will be described for the first time in terms of its functions, and then in the characteristics of its role when introduced into the sanitization system.

The Venturi vortex device has a main stream inlet, an additional stream inlet, and an outlet for the resulting mixed stream. Between the inlet of the main stream and the outlet of the mixed stream are the inlet channel of the main stream, a narrowed part with a reduced diameter, a neck and an expanded part with an increased diameter. The inlet of the main stream is located perpendicular to the axis of the stream flowing through the outlet, and along the axis tangential to the inlet channel, thus forming a high-speed vortex stream. The tangential displaced inlet of the main stream is primarily responsible for the occurrence of the vortex effect, and as a result, for the high speed of the main stream, and, thus, for the high degree of mixing of the main and additional flows.

According to this embodiment, the additional flow inlet includes a hollow needle-shaped tube a located centrally inside the device. The inlet of the additional flow is buried inward of the neck portion, and thus forms an annular channel around the inlet. One or more outlet openings of the additional stream in the inlet of the additional stream introduces the additional stream into the neck portion in order to mix it with the main stream.

The present Venturi vortex device has the advantage that the gas or additional liquid stream is dissipated when there is no need to use additional energy to introduce gas. The present invention has the advantage that it uses the venturi effect to draw an additional stream into the main stream.

A further advantage of the Venturi vortex device in the present invention is that the tangential inlet of the main stream imparts rotational motion to the entire stream inside the annular channel, and thus creates an annular stream by introducing an additional jet. This is the reason that a significant part of the main stream reaches a high speed, and most of the main stream is in contact with the additional stream. The present invention is also suitable for cleaning and changing the number of holes, their location and size, or changing the diameter of the needle-shaped pipe, and changing, respectively, the cross-sectional area of the neck.

An embodiment of a Venturi vortex device according to the invention is described below.

According to one embodiment of the invention, the venturi vortex tube has a cylindrical body with a main flow inlet, an additional flow inlet and outlet. Between the inlet of the main stream and the outlet there can be: a screw inlet channel of the main stream, a narrowed part with a reduced diameter, which has the shape of a truncated cone, and preferably has a continuous curved shape, mainly a cylindrical neck part, and an expanded part with an increased diameter having the shape of a truncated cone.

In this embodiment, the inlet of the main stream is perpendicular to the axis of the outlet stream and tangentially to the helical inlet channel, thereby contributing to the occurrence of a high-speed swirl flow. The speed of the rotating fluid flow increases with decreasing diameter, thereby reducing static pressure.

The Venturi vortex device according to this embodiment of the invention has an additional flow inlet including a centrally located hollow needle, recessed inward of the neck portion. An annular channel is formed between the needle and the walls of the neck. In this embodiment, the hollow needle ends in the throat portion, in the outlet located parallel to the axis of the outlet stream. Alternatively, the cannula may pass through the neck portion, ending in the expanded portion and having a sharp end. A plurality of outlet openings are formed in the needle-shaped tube perpendicular to the axis of the needle, and they can be arranged so that an additional flow is introduced into the neck portion.

The inlet needle-shaped channel of the additional flow can be formed as part of a separate housing, and can be removed from the Venturi vortex device, or be permanently attached or attached to the main housing using a rivet-fit configuration, fasteners, thread, or other methods of fastening. The inlet needle-shaped channel of the additional flow can be sealed using O-rings or other similar methods, which, obviously, can be identified with know-how.

The body of the inlet of the auxiliary stream may include a check valve to prevent the main stream from flowing back from the inlet of the secondary stream when the main stream is not fast enough to create a vacuum.

The movable body of the input channel of the additional stream allows you to clean the inlet channel of the additional stream and / or change its position, thereby contributing to a change in the diameter of the needle-shaped channel or the size of the holes, their location and / or quantity to control the mixing proportions and / or flow rates.

A Venturi vortex device, according to an embodiment of the invention, may have a plurality of guide devices in the expanded part. These guiding devices can be parallel to the axis of the output stream and arranged radially. They can interact with a rotating fluid stream to increase the intensity of mixing.

Fig. 8 is an isometric view of a venturi device 800 according to an embodiment of the invention. Shown are main stream inlet 802 and mixed stream outlet 804. Using arbitrary connection means 806, it is illustrated how one of the possible methods of a Venturi vortex device can be connected to other components, for example, located inside the sanitization system.

FIG. 9 illustrates an end view of a Venturi vortex device according to an embodiment of the invention shown in FIG. The inlet inlet 902 is illustrated, along with the position of the inlet inlet 802 of the main stream, which is clearly depicted with an axis tangential to the annular shape of the inlet of the main stream, which is visible from the outside as the outer 904 of the inlet of the main stream.

Figure 10 illustrates a section through the center of the image of the venturi device 800 of Figure 8, taken along the line BB In Fig.9. This illustration shows a mixed flow outlet 804, a connecting device 806, an additional flow inlet 902, and an outer part of the main flow inlet channel 904. Additionally illustrated are the main flow inlet channel 1002 having a constricted portion 1004, a neck portion 1006, and an expanded portion 1008. In the center is a hollow needle 1010, resulting from an additional flow inlet 902, and ending in the neck portion 1006 at the sharp end 1012. Many outlet openings 1014 additional flow, in this case four, two of which are shown, provide the introduction of an additional flow in the accelerating main flow in the throat portion. It should be understood that this invention requires a minimum of outlet openings for one additional stream, although many such openings are shown in this image. In the expanded portion 1008, there are a plurality of guiding devices 1016 that interact with a rotating fluid stream, resulting in a vortex effect, so as to increase the mixing efficiency of the secondary and main streams. It should be understood that guiding devices are not required in this apparatus, and in the case where one or more guiding devices exist, at least one may be used. In this case, 4 guiding devices are included, three of which are shown here in section. The expanded portion 1008 is arranged adjacent to the outlet of the mixed stream to create a low pressure zone having a vacuum effect that draws flows through the interior of the Venturi vortex device to discharge 804 of the mixed stream.

A venturi vortex device incorporated in a variant of the sanitation system according to the invention is located downstream of the ozone generator. An additional stream arrives, thus providing ozonated air from an upstream ozone generator. Ozonated air is drawn in using a vacuum created in a Venturi vortex device, or, alternatively, can be pumped at the inlet of the additional flow. Water pumped out of the container by a pump, which is accessed through a double check valve supplied to the inlet of the main stream, forms turbulences in the inlet channel of the main stream, and using the Venturi effect, the water is drawn through the narrowed part, causing increased pressure, and passes through the neck part, which has the outlets of the additional stream, thus allowing efficient mixing of ozone and water using high pressure and acceleration of water, and further mixing takes place in the expanded part, where ozone and water interact and mix further. At the mixed-stream outlet, most of the ozone is dissolved in water, and only part of the additional ozone remains as a separate gas. For the ozone gas remaining in this system, a gas-liquid separator having a gas release valve as an integral element can be introduced downstream of the mixed stream.

Ozone generator

The ozone generator introduced into the system according to the invention is a low-cost corona generating apparatus. Ozone can be generated by an electric discharge such as a “spark discharge”, which splits an oxygen molecule into two oxygen atoms. This electrical discharge is also referred to as a “corona discharge". These unstable oxygen atoms combine with other oxygen molecules, and this compound forms ozone.

An ozone generator according to an embodiment of the invention is an ozone generator of a predominantly corona discharge. The corona discharge ozone generator includes two cylindrical, insulating end caps, a high voltage electrode, a ground electrode, and a dielectric material. The design of the ozone generator with a large inner diameter, relative to its length, takes into account heat transfer and, consequently, the sequential supply of ozone over time.

The end caps are designed to maintain a constant spark gap between the dielectric and the high voltage electrode. The air enters the spark gap tangentially, creating a swirling motion throughout the ozone generator, and thus increasing the time delay between the dielectric and the high voltage electrode, which increases the efficiency of ozone output. The end caps have large open ends that are close to the inner diameter of the high voltage electrode, taking into account the heat transfer during the corona discharge process. Alternatively, a fan may be installed on the end caps to provide convection cooling of the generator. However, due to the designed large internal diameter of the ozone generator, which provides good heat transfer, the presence of a fan is optional.

The plugs are attached to the grounded shield and dielectric with glue.

The dielectric material is preferably silicon borate glass, but other materials, such as ceramic or thermoplastic, can be used.

A high voltage electrode constructed from a welded or seamless stainless steel pipe with a large internal diameter promotes heat transfer during the corona discharge process.

According to this embodiment, the grounded shield includes a thin, seamless steel foil that is laminated at high temperature and has an adhesive layer on one side. This foil then adheres to a dielectric material, such as glass, and thus forms a grounded shield.

The relative distances between the grounding shield, the dielectric material and the high voltage electrode are different in order to avoid arcing between the components through the end caps.

An alternative configuration of this ozone generator includes an air pump in fluid communication with a power supply conduit to a corona discharge ozone generator, for example, inside the base when the system is mounted in the base. The air pump is adapted to pump air through a corona discharge ozone generator, thereby providing a sufficient supply of incoming air. Charged air emerging from a corona discharge ozone generator can then be bubbled into a liquid container using a sprinkler or porous ceramic structure. In this case, the presence of a Venturi vortex tube is not necessary, since ozone is introduced directly into the container. If several containers are provided, each container is provided with a sprinkler and is in fluid communication with the base. Of course, the combination of an air pump, along with a design including a Venturi vortex tube, is included in the system of the invention.

11 is an isometric view of an ozone generator 1100 according to the invention. End caps 1102, 1104, ozone outlet 1106, and an air inlet 1108 are shown. Both the inlet and outlet are perpendicular to the axis of the gas flow through the ozone generator, and both are tangential to the circumference of the ozone generator. Thus, air enters the generator, moves along a spiral path through the ozone generator, and passes near the electrodes. Thus, the spiral route allows you to maintain the same amount of air with a longer exposure time in the generator, resulting in an increased ozone content per unit volume of air entering the ozone generator.

12 is a top view of the ozone generator shown in FIG. 11. End caps 1102, 1104, ozone outlet 1106, and air inlet 1108 are shown.

Fig.13 is a section through the center of the image shown in Fig.11, drawn along the line D-D of Fig.12. High voltage electrode 1302 is marked.

Fig is a detailed section of the configuration of the dielectric, adhesive layer and the grounding electrode of the ozone generator isolated from the detailed section E of Fig. 13. The ground electrode 1402 in this image made of stainless steel foil is shown as the outermost layer, the high temperature adhesive layer 1404 is located below the ground electrode, and the dielectric 1406, in this case a glass pipe, is shown directly below the adhesive layer. In one example, a typical voltage for an internal high voltage electrode is about 4000 V, while for an external ground electrode, 0 V.

The outlet of the ozone generator, when it is included in the system according to the invention, is upstream of the inlet of the additional stream of the Venturi vortex tube and is in fluid communication with it, thus ensuring the flow of ozone in the additional stream through the outlet openings of the centrally located hollow needle-shaped channel.

The remaining system components, as can be understood from the description below, are optional. None of the following components are required to perform the function or operation of the system in this invention. However, according to an embodiment of the invention, each of the components mentioned below exists in the system.

Centrifugal, gas-liquid separator with integrated gas release valve.

In an embodiment of the sanitization system of the invention, a centrifugal gas-liquid separator may be used. This separator is periodically referred to herein as a “degasser." The separator includes an integrated gas release valve and helps to remove entrained gases from the liquid stream. More specifically, when ozone gas is drawn into the ozonated water stream, gaseous ozone can be removed using this separator.

The gas-liquid separator is in fluid connection with the outlet of the mixed flow of the Venturi vortex device, allowing the removal of entrained gas from ozonated water. A gas-liquid separator provides effective removal and exhaust of potentially harmful gaseous ozone, allowing dissolved ozone to remain in the liquid phase. Thus, the system provides the formation of degassed ozonated water.

According to an embodiment of the invention, the gas-liquid mixture is introduced tangentially into the screw channel through the gas-liquid mixture inlet, from which the high-speed vortex begins. A swirling gas-liquid mixture rises through the pipe and drives the gas to the center of the vortex device, and the liquid to its periphery. As the gas-liquid mixture rises through the pipe, a portion of the liquid is discharged along the groove around the pipe, which drains through the liquid outlet. The remaining gas-liquid mixture rises into the valve chamber. The liquid level in the valve chamber affects the position of the float, which opens and closes the gas outlet, if necessary.

In one embodiment of the invention, the centrifugal force is used in the gas-liquid separator and the gas release valve is turned on. The gas-liquid mixture enters under pressure through the nozzle tangentially into the screw channel in the base of the separator. The gas-liquid mixture is driven into a rapidly rotating vortex and rises through the pipe. As the vortex rotates, a centrifugal force is created, displacing the lighter gas to the center, and the heavier liquid to the pipe walls. Part of the water is discharged along a groove extending along the inner surface of the pipe into the annular chamber around the pipe, and then discharged through the exhaust pipe. The remaining gas-liquid mixture rises into the valve chamber. The float, depending on the liquid level, can either open or close the hole. Gas is released from the orifice depending on the liquid level, thus maintaining the pressure in the system.

According to this embodiment of the invention, the float may be in the form of a torus, allowing the gas to pass through its center, while minimally disrupting the vortex movement. Alternatively, the float may have a torus shape with a closed center, as well as a spherical shape. The float may be in contact with the hole using the lever arm and a seal introduced into the arm arm. The lever arm improves the buoyancy and gravity of the float, effectively seals the hole when the liquid level is high, and pulls the plug out of the hole when the liquid level drops. In this case, the lever arm effectively pulls the plug out of the hole in spite of the internal pressure of the system, allowing gas to escape. Alternatively, an electronic float switch can be used in place of the float and lever arm, and the valve can open and close to remove air.

The gas-liquid separator pipe can be either cylindrical or in the form of a truncated cone with a diameter increasing from bottom to top.

The plug at the base of the gas-liquid separator, forming the bottom of the screw channel, is movable, thus allowing to drain and / or clean the separator. The plug on the valve chamber may include a gas outlet and a pivot point for the lever arm. This plug can be either permanently attached to the separator or removed for inspection and cleaning of the valve block and / or valve chamber.

The plug may include fasteners for the partition. The partition has a cavity in its center and aligns with the central axis of the float. The cavity allows gas to pass through the partition and exit through the hole. The cavity also allows you to connect the lever with the float. When a partition is installed, it reduces the likelihood of fluid flowing out through the gas passage.

FIG. 15 is an isometric view of a centrifugal gas-liquid separator 1500 according to an embodiment of the invention. An inlet 1502 of a gas-liquid mixture is shown having a flow axis tangent to a rounded channel of the separator. This configuration contributes to the formation of high-speed swirl. A central pipe 1504 is located above the inlet through which the rotating gas-liquid mixture rises. The fluid outlet 1506 is located above the center pipe. Gas outlet 1508 is located on the separator cover. An optional connecting device 1510 for supporting a gas-liquid separator inside the sanitization system according to the invention is shown.

Fig.16 is a top view of the gas-liquid separator of Fig.15. The fluid outlet 1506, the gas outlet 1508, and the connecting device 1510 are shown.

Fig.17 is a section through the center of the gas-liquid separator of Fig.15, drawn along the line CC of Fig.16. In addition to the gas-liquid mixture inlet 1502, a central pipe 1504, gas outlet 1508, lever arm 1702, lever arm retainer 1704, lever arm pivot point 1705, valve chamber 1706, lever arm seal 1708, valve chamber plug 1710, float 1712, vortex tube 1714 are shown and a separator base 1716. As can be seen from this transverse section, a narrow gap 1718 at the top of the central tube allows fluid to flow between the vortex tube 1714 and the valve chamber 1706.

Although a gas-liquid separator is an optional component of the system when it is included in it, some characteristics are shown which are favorable for the embodiment of the invention described herein. As in the small-sized systems of the invention, where the gas-liquid separator occupies about 3-6 inches in total height (about 4 inches), the following sizes can be used in this embodiment. The narrow gap 1718 may be 0.01-0.1 inches, and preferably 0.02-0.06 inches. A small ledge where a narrow gap meets the central pipe 1504, or either any kind of expansion of the pipe extending upward, are a significant improvement. The height of the center pipe 1504 may be about 1 inch for a device variant with a total length of 4 inches. However, for separators with a total height of about 3-6 inches, the optimal height of the central pipe is about 0.5-3 inches, respectively. In size, the height of the central pipe can be about one quarter of the height of the entire separator. The angle of inclination of the central pipe can be from about 0; no angle of inclination to 15 °.

The inlet and the separator tube can function as a turbo mixer to facilitate the dissolution of ozone in water. In the arrangement in which the inlet pipe is located tangentially to the longitudinal axis of the separator and in which there is a quick inflow to the inlet, this effect is achieved, and good mixing occurs.

As an alternative to a gas-liquid separator, a mixing tube or “bubble breaker” suitable for breaking bubbles in a liquid stream may be used. A set of mixing pipes with bubble breakers performs the effective work of dissolving ozone in water and can be used instead of ozone degassing. Mixing pipes with bubble breakers do not release excess ozone, but they can be used in accordance with some regulatory requirements, which require removal and / or destruction of ozone.

Capacitive high voltage detection system to detect high voltage failures.

The corona discharge generator depends on the supply of high voltage and high frequency electricity for ozone production, which is necessary for an embodiment of the invention that uses an ozone generator. The guarantee that the generator will receive this energy is favorable for verifying that the unit is functioning properly. A low-cost and trouble-free recognition system is described, periodically referred to here as a "high voltage detector", which is able to detect the supply of electricity to the ozone generator.

The high voltage detector uses the fact that a high frequency and a high voltage supply to the ozone generator can provide a sufficiently large signal to the detector circuit through a very small capacitor. This capacitance is created between parts under high voltage and the input of the detector circuit.

Capacitance is created by simply connecting one end of the wire to the input of the detector circuit, and wrap the other end around an insulated high voltage ozone generator power wire.

Alternatively, other means of attaching a high voltage detector wire in close proximity to a high voltage power cable or other high voltage parts can equally be used. Other possible arrangements for conducting and insulating parts that create and use capacitance between the high voltage parts and the input of the detector circuit may be apparent to those skilled in the art and are covered by the invention.

On Fig presents a diagram of a capacitive measuring transducer or high voltage detector, which can be used as an embodiment of the invention. Capacitance due to the proximity of conductors provides signal transmission. A high voltage detector is shown in which the current path, which complements the circuit to a common one, is provided by wires, or there is a stray capacitance in the current path. The high voltage detector contacts the microprocessor to detect high voltage failures.

As shown in FIG. 18, a high frequency alternating current is supplied to the ozone generator. This embodiment of the high voltage fault detection system 1800 operates as described below. The supply of high voltage to the ozone generator occurs through the supply wire 1802 of the ozone generator. This wire is connected to a high frequency AC source 1804 for an ozone generator 1806. Wire 1808, located as close as possible to the high-voltage power supply of the ozone generator, is also located as close as possible to wire 1802 in part of its length. This creates a small capacitance, designated as capacitor 1803.

The high-frequency and high-voltage signal on the wire 1802 causes a small current towards the flow through the capacitor 1803. This current creates a voltage that is installed on the wire 1808 and at the input of the high voltage detector 1810.

The current path 1812 in the wire 1808 is made using the track 1812, shown by a dashed line connecting to the general block diagram 1814. This current path can be equipped with a stray capacitance or a physical component such as a wire, resistor, capacitor, or other device with a small impedance.

The high voltage detector circuit 1810 can be implemented in many ways that can be understood by those skilled in the art in the design of electrical circuits. A circuit 1816 illustrating a typical implementation of a high voltage detector is a monostable standby multivibrator with trigger functions set to the “on” position when voltage occurs on wire 1808. The monostable standby multivibrator 1818 returns to the off position when there is no voltage at each point, and can be triggered by a signal applied to wire 1808. The microprocessor 1820 monitors the operation of the trigger to verify that it is in the on state most of the time ". If the processor detects that the trigger is not in the on position for an acceptable period of time, the processor detects a failure in the high voltage supply.

In this embodiment of the invention, the system is further provided with a high voltage and high frequency power detector for checking the supply of the necessary power for the corona generator. The detector includes a wire terminal or “first wire” that is in contact with a high voltage and high frequency terminal to a corona discharge generator; a wire terminal or “second wire” which is in close proximity to the high voltage and high frequency terminal to the corona discharge generator; and detection circuit. The detection circuit can be driven both externally and through the capacitance of the detecting wire. In this embodiment, the capacitance arises due to the maximum proximity of the first and second wires. The detection circuit is connected to the second wire in order to obtain a detecting capacitance. The circuit has a microprocessor and a trigger for checking the supply of electricity to the corona discharge generator.

Redox sensor.

The service time of the sanitization system can be controlled either manually or automatically. In the case where automatic control is desired, it is possible to control both with the help of time and with the help of levels of ozone concentration in the resulting ozonated water. Thus, a sensor can be introduced into the system to detect water ozonation. The sensor can be located anywhere within the system of the present invention while ensuring its contact with ozonated water.

The sensor described herein is one of a number of sensors that can be incorporated into the system of the invention. In this embodiment, the comparative electrode and the ORP probe are in fluid contact with the sanitization system. The first electrode, which is the reference electrode, is made of silver material. The electrode may be solid silver or with silver as a plating on the surface of the substrate. The ORP probe is a noble metal — platinum or gold, and can be hard platinum or gold, or the metal can be plated on the surface of the substrate.

In a preferred embodiment, the reference electrode and the ORP probe are electroplated coatings on the surface of stainless steel screws. The screws are then inserted into the inlet pipe so that the bottom of each screw is in fluid contact with the water flow passing through the pipe. The wire leads are attached to the screws using cable lugs. When ozone reaches the water passing by, the redox potential is established. This potential is translated by standard electronic components of the system and, therefore, controls the time of service of the system.

Screws are suitable for mass production, and the plating process for both silver and platinum is well known and widely used by those skilled in the art. The sensor kit is simple and economical.

FIG. 19 illustrates the location and preferred embodiment of an ORP sensor in a mating member 402 of a sanitization system, such as one of them is shown, attached to the double check valve 100 in FIG. A central pipe 404, a reverse flow pipe 406, and a central reservoir 604 are shown. The arrangement of electrodes 1902 and 1904 near the central pipe through which flow enters the system is illustrated.

Gravity filter and other possible water purification technologies.

The invention may include a gravity filter. In such an embodiment, the gravitational filter may be a compressed carbon filter between tissues, or a fabric filter without activated carbon. The carbon filter may be placed upstream than the liquid container, or may be integrated into the liquid container in the form of an upper reservoir dividing the volume of the container into an upper reservoir and a filtered water reservoir. Preferably, the gravity filter is not lowered into the water inside the filtered water tank. However, the system may include a gravity filter, which extends down into the filtered water tank, as an alternative to a filter that does not. Such a filter may be in the form of a removable, disposable and / or rechargeable cartridge.

Additional cleaning technologies can be used in addition to the system. For example, electrodes; ultra-, micro-, nanofiltration; UV ultraviolet light source; or additional aeration / oxygenation. Additional cleaning technologies, if any, are used, as appropriate, to affect the water passing through the system. As an additional cleaning technology, a sanitization technology based on a pulsating electric field, which includes electrodes for disinfecting and treating water passing through them, can be used. For example, such a technology is described in International Application No. PCT / CA04 / of January 9, 2004, pending, the contents of which are incorporated by reference.

An embodiment of the invention comprising gravity filtration includes a container having an upper reservoir for filling with unfiltered water. The upper tank has a lower hole; a filter medium in the lower opening of the upper reservoir for filtering unfiltered water when passing through it; and a lower reservoir for receiving filtered water passing through the filter medium. The filtered water tank has a bottom opening that fits into the double check valve.

In an embodiment using gravity filtration, the container may include a jug having a flat sheet of pressed carbon between the fabric as a filter medium. A sheet of pressed coal is located at the bottom of the upper reservoir. The container may be provided with a lid to close the upper tank. The water collected in the upper reservoir is slowly filtered through a sheet of pressed coal and flows through it into the lower reservoir of the pitcher. The jug can be adapted for installation in a special place on the base. As a further alternative, the air pump in contact with the lower reservoir of the pitcher supplies air to the sprayer available in the lower filtered water reservoir. In this regard, the bubbles released into the water are trapped inside the jug, contributing to the further purification of water. In this embodiment, a plastic reflector may be located above the atomizer to facilitate the circulation of bubbles. In practice, this contributes to the purification of water both by filtration through a pressed carbon filter and by aeration / oxygenation through a pump connected to the filter. A double check valve can be included in this option to ensure that the corresponding flow into and out of the pitcher flows through to the end. An electronic control can be mounted in the base to ensure that the jug is on the base. Although it would be desirable for the compressed carbon filter not to fall below the bottom of the upper tank, it is understood that a compressed carbon filter that is lower than the bottom of the upper tank and water contained in the lower tank can be used.

Reusable sanitation system.

The system according to the present invention is a reusable sanitation system having a liquid container and components promoting the formation of ozone, ozonation of the liquid, and circulation of the liquid back into the container. Other liquid purification technologies may be used in conjunction with the technologies disclosed herein. Additionally, optional tools can be used to remove excess undissolved ozone, determine ozone levels and eliminate excess ozone. The fluid container may possibly be mobile. Components can be placed inside the base on which the container is located.

According to an embodiment of the invention, the system components are placed inside the base on which the container can be placed, or with which the container is in contact when the container is stationary. These components include a pump, an ozone generator, and a Venturi vortex device for incorporating ozone into the main stream. A double check valve to ensure simultaneous flow of fluid into and out of the container is connected to the container and may have a mating element inseparable from the base, for an embodiment in which the container is removable. A centrifugal gas-liquid separator or degasser is included in the base. As a further option, an ozone destructor, an ORP redox potential sensor, and electronic control equipment can be included. A container or several containers can be either mobile or fixed inside the system. In the case when the container is non-removable and does not move easily in the system, it can exist in the form of a modular tank. This type of container may be applicable to large projects where the user does not necessarily require a portable container. However, for small-sized and residential applications, it may also be desirable to have a container with a fixed position, non-removable, from which aliquots of ozonized water can be taken, for example, through a tap or through a pipeline to the selected device.

In one embodiment, the system includes a plurality of transportable containers. Of course, the system described in the invention requires only one container and not necessarily a removable one. An embodiment of the invention that uses more than one container and containers that are removable are discussed below. This embodiment describes electronic control equipment including an automatic identification system for determining the type of liquid container associated with the base and for activating the corresponding program. For example, a fluid container is identified which is required for drinking water where a low level of ozonation may be desired. Alternatively, if a container is defined that can be used to clean surfaces, a high level of ozonation is desired.

As an alternative to the automatic detection scheme, the user can select the appropriate cycle. The processing time can be manually controlled or an automatic control based on the time and / or concentration of ozone in the resulting water can be set.

Mobile containers include a double check valve at their base, which is in contact with the base unit. This design allows water to flow out of the container and flow into it at the same time as long as the single connection point is used.

In one embodiment, when the container is placed on the base, an automatic detection circuit is activated. The corresponding program is possible, one special program for this container is activated, and the ready indicator is highlighted. The user then activates the process by pressing a button. The pump pumps water out of the container and pumps it through the venturi. The venturi device has a gas inlet through which ozone-enriched air produced in an ozone generator is passed. An ozone generator can be a corona discharge type generator, and convert part of the oxygen from air to ozone, and it can also have another acceptable type of work. Ozone is mixed with water in a venturi to create ozonated water. The ozonated water then passes into a centrifugal gas-liquid separator, in which undissolved gases such as air and undissolved ozone are removed, while the remaining dissolved gases are present in the ozonated water. The gas to be removed can be sent to an ozone destructor, which converts ozone into oxygen and releases it safely into the atmosphere.

Alternatively, a gas-liquid separator may direct the displaced gas back to the inlet of the venturi for re-dissolving in water or equally efficiently direct the displaced gas into the inlet of the ozone generator. Ozonated water leaves the gas-liquid separator and is sent back to the liquid container. The cycle continues until a predetermined time and / or until the desired ozone concentration is reached. The ORP sensor is located at the entrance to the system, which continuously monitors the level of ozone in the water and monitors the cyclic process in the unit.

As an alternative to re-dissolving the gases displaced from the gas-liquid separator, many regulations prescribe the release of such ozone-containing displaced gases into the atmosphere. Thus, in these regulations, the regulation does not allow either the processing of displaced ozone-containing gases or the necessary destruction of ozone. In North America, existing guidelines allow acceptable levels of displaced ozone to be determined.

When the process is completed, a message is made to the user by a light and / or sound signal indicating that the container can be removed.

Each container may include a double check valve on its base, which is in contact with the base and allows the container to move without leaks. The non-return valve allows water to flow out and return to the container without requiring additional connections. Water flows out of the container by means of a pump and other means through a venturi device, through a degasser and substrate into the container. The process continues until a predetermined time and / or achievement of the required ozone concentration. Ozone is produced in an ozone generator and mixed with water in a venturi device. A gas-liquid separator removes undissolved ozone and, at the same time, entrained air. Ozone removed by a gas-liquid separator is dissociated by an ozone destructor and is safely released to the atmosphere.

It is possible that the container had the form of a jug for the sanitary treatment of drinking water. The container may also be in the form of a glass and a strainer for the sanitary processing of fruits and vegetables. Alternatively, the container may be in the form of a spray bottle for containing ozonated water applied to the surface, or a lined reservoir for cleaning surfaces. The container may also be in the form of an internal and external container for sanitizing small objects such as dentures, teats for babies, etc. Also, the container may be a decanter for containing ozonated water when a larger amount is required. Examples of this include gravy for foods such as meat, or rinsing dishes or hands.

The sanitation system has a variety of applications for both domestic and personal consumption, and for industrial and / or medical use. Examples of such uses include: preparing purified drinking water or producing ozonated drinking water for sanitizing surfaces and objects. Ozonated water obtained in the sanitization system can be used to treat diseases such as acne that are of bacterial origin, fungus on the legs, for sanitizing cuts, for local skin treatment, and cleaning medical devices. In industrial applications, ozonized water obtained according to the invention can be used for cooking. For example, commercial use when cleaning surfaces in restaurants, food processing enterprises such as meat processing plants, food packaging enterprises such as a factory or factory, in supermarkets where fresh food is required. The shelf life of fresh products can be extended by periodically spraying them with ozonated water obtained according to the invention. For employees, it may be convenient to access ozonated water in the production and public premises. Plants and flowers can also be sprayed and watered with ozonized water obtained according to the invention.

For home use, vegetables and fruits can be washed in a container in the form of a strainer attached to the base. For oral care, ozonated water thus obtained can be used for brushing teeth, toothbrushes or as a mouthwash. Care for household wounds may include the use of ozonated water instead of more powerful products such as rubbing alcohol or hydrogen peroxide. As deodorants, ozonated water thus obtained can be used to spray surfaces or internal surfaces, such as shoes.

Additionally for home use, the system can be installed as a counter-current model or as a built-in upstream water supply unit for home appliances. By using ozonated water for a washing machine or dishwasher, the amount of detergent required can be reduced or completely eliminated.

Many other industrial and domestic applications can be considered as know-how and are included in the scope of the invention.

20 is a schematic diagram of a reusable sanitation system according to the invention. 20 shows a base 1 and a movable container 2. The treatment container includes a double check valve 3, which allows water to flow in and out of the container through a single connection. When the container is placed on the base, a double check valve contacts the pipe 21. An automatic detection circuit included in the electronic equipment 9 starts the corresponding program to start the ozonation process.

Electricity is supplied using 115 V alternating current through wires 20. Electronic equipment converts the power consumed from the network into 12 V direct current supplied to pump 4 by means of wires 19 and into high voltage alternating current for ozone generator 6 by means of wire 18.

When the system is activated, water flows from the container through a double check valve into the pipe and through line 10 to the pump. Then the water flows through the pipe 11 and enters the Venturi vortex tube 12. The ozone generator is a corona discharge generator that turns part of the oxygen in the air into ozone.

Water, together with bubbles containing ozone and air, leaves the venturi device through line 14 and enters the centrifugal gas-liquid separator 7. The centrifugal force generated in the gas-liquid separator pushes all the air and undissolved ozone out of the water. The extracted gas is directed to the ozone destructor 8 through the pipe 16. The destructor contains a catalyst, preferably KARULIT ^tm (KARULIT is a registered trademark of Carus Corporation from Peru, I11), which decomposes ozone into oxygen and releases it into the atmosphere with safe air 17.

Water containing currently dissolved ozone is sent back to container 2 through a double check valve through line 15 and pipe 21. The process continues until the program ends.

A control button 2502 for transmitting a lining image to the display is shown on the front side of the base, which is accessible to the user. A control button 2502 for transmitting a lining image to a display may include any number of controls or viewing windows. Such controls or viewing windows may include an on / off button, a program selection button, a “ready” light to indicate to the user when the liquid in the container has been sufficiently processed, or any other type of display that will inform the user about corresponding signal, but this list is not limited. One person skilled in the art can easily determine other types of controls or viewing windows to start the lining. In this embodiment, the data processing devices are measured so that they can be placed, taking into account their size, into the base compactly, taking into account the placement of the counter-current model or the installation of the unit. However, it should be understood that the components should not actually be placed inside the base, for example in enlarged systems that are stationary installations.
