First, the micro-bubble (Micro-Bubble) refers to very fine bubbles having a diameter of less than 50㎛ (about half of the thickness of the human hair) can be produced through the bubble generator. Such microbubbles can generate ozone water having a sterilizing effect in the field of medical and food manufacturing and can effectively decompose hardly decomposable substances, and thus can be applied as a technology for water purification and cleaning. Specifically, the general bubble rises in water and disappears from the water surface, but the microbubbles float in the liquid, so the rising speed is low, and the self-pressing effect is high, solubility with the gas is high, so it is effective to use ozone as a gas in the bubble. The pre-radical generated when broken by the pressure of the bubble can be used to separate harmful substances in the sewage, and at the same time, it can be used to purify and clean water using high properties such as cleaning effect by electrostatic attraction such as pollutants and metal ions. It is to use.

Microbubbles of the present invention can be prepared by injecting the above-described high pressure pump 100. Here, the washing water is a mixture in which the washing composition is added to water. At this time, the ratio of the cleaning composition in the washing water can be adjusted according to the degree and situation of contamination. The microbubbles are generated through the washing water to further remove the contaminants.

The method of generating a microbubble includes a mechanical method, a chemical method using a chemical agent, a method using a supersaturation of gas, etc. Among them, the present invention applies a mechanical method of applying pressure to the pump 100 with a motive force. The mechanical method of applying pressure to the pump 100 with a motive force can be used to outflow the generated microbubbles out of the water, it is easy to continuously generate the microbubbles.

1 is a conceptual diagram showing a schematic configuration of the generating apparatus of the present invention, Figure 2 is a cross-sectional view showing a basic embodiment of the production chamber 200 of the present invention.

Microbubble generating device according to the present invention, a water source, a pump 100 for generating pressure to receive and compress the water supplied from the water source, the pump pipe 120 for receiving the compressed water from the pump 100 The microbubbles generated in the production chamber 200 and the production chamber 200 having a generation tank having a chamfer 230 therein to be connected to the pump pipe 120 to generate the microbubbles are generated as cleaning objects. It includes a discharge unit 300 for supplying.

The water source is to supply water to the pump 100, such as a large water tank or a water supply device, and is not limited to a specific type and form.

The pump 100 serves to compress the water supplied from the water source, and is connected to the water source for supplying water and the pump pipe 120 for introducing the compressed water into the production chamber 200. There are various types of pump 100. In the present invention, the high pressure pump 100 is used to provide a driving force for microbubble generation. The high pressure pump 100 is a power device capable of generating a high pressure for transferring water, and performs a function of discharging water at a high pressure. By using the high pressure pump 100, the water in the pump 100 may be compressed to a high pressure, and the compressed water may be introduced into the production chamber 200 at a high injection pressure. A high injection pressure is equivalent to a high rate of inflow of compressed water. As a result, the high pressure pump 100 functions to compress the water at a high pressure and spray the water at a high pressure to generate microbubbles better. However, when the high pressure pump 100 of excessive pressure is used, the size of the pump 100 becomes large, and a problem may occur in the apparatus due to too high pressure.

In addition, since the size of the microbubbles does not become smaller any more than a specific pressure, the appropriate pressure of the high pressure pump 100 to increase the size and the production effect of the microbubbles is preferably set to 0.4Mpa to 0.8Mpa. In other words, the high pressure pump 100 used in the present invention injects water at a pressure of 0.4Mpa to 0.8Mpa. At this time, when the pressure is based on the volume of the production chamber 200 to be described later is 100m3 to 300m3.

 The production chamber 200 has a space for accommodating water therein and is a space in which microbubbles are generated. The production chamber 200 is connected to a pump pipe 120 extending from the pump 100 and an outlet for discharging the generated microbubbles to the outside. That is, the production chamber 200 receives the high pressure water compressed by the pump 100 through the pump pipe 120, and washes the microbubbles generated in the production chamber 200 through the discharge unit 300. To supply.

The generation chamber 200 is preferably formed in a specific shape for efficient generation of microbubbles, which will be described later.

The discharge part 300 serves to supply the generated microbubbles to the cleaning target. The discharge unit 300 supplies the microbubbles generated in the production chamber 200 to the external cleaning object in a structure that connects the production chamber 200 and the cleaning object. For example, the discharge unit 300 may be configured as a separate pump 100 to provide power to be transferred from the production chamber 200 to the cleaning object, or to be cleaned only by the driving force of the pump 100 described above. It may also be a connector for supplying water.

In the present invention, the object of cleaning means an object to be cleaned by microbubbles, and may be classified into an object such as a boiler tube extending to a predetermined length or a pipe or a water tank having various other uses. In other words, the cleaning object of the present invention is not limited to a specific kind and use.

The basic functions and actions of the present invention through such a configuration are as follows.

The pump 100 receives water from a water source. The pump 100 compresses by applying high pressure to the water supplied from the water source. The pump 100 introduces the compressed water into the production chamber 200 through the pump pipe 120 at a high pressure injection pressure. The generation chamber 200 allows microbubbles to be generated in the inflowed water, and the water in which the microbubbles are generated in the production chamber 200 is transferred to the discharge unit 300. An end portion of the discharge part 300 is connected to the cleaning object, and high pressure water is injected to the cleaning object through the discharge part 300.

Thereby, it is possible to have an environment in which the cleaning object can be cleaned cleanly on the basis of which micro bubbles can be easily generated.

In addition, as can be seen from Figure 2, the production chamber 200 of the present invention consists of a rectangular parallelepiped shape having a space (production tank) that can accommodate water therein. In other words, in the state where the cross-sectional shape is composed of a rectangular parallelepiped shape having two long sides and two short sides, it is a structure having a generating tank having a chamfer portion 230 which is chamfered to round the corners.

The chamfer 230 refers to a portion in which the edge of the production tank 200 of the production chamber 200 is chamfered, and is formed at each corner, that is, four corners. Here, a chamfer means a part made by cutting out the corner part of the member which has each cross section, and has many kinds, such as a flat surface and a round surface. In the present invention, the chamfer 230 means that the chamfer (chamfer) process so that the corner is rounded bending. In other words, the chamfer 230 has a shape in which four corners are rounded and bent in the cross-sectional structure of the production chamber 200 having a rectangular parallelepiped shape.

As described above, in the case of the production tank including the chamfer portion 230 with the chamfered corners, when the water inside the production tank collides with the inner wall of the production tank, the change in the direction of movement of the water may be caused by Larger than the generating bath of the shape. That is, as the change in the direction of movement of the liquid increases, the pressure in which the liquids in the production tank collide with each other increases, which may lead to destabilization of the overall liquid movement in the production tank. In other words, the chamfer 230 provides a function in which the microbubbles are better generated by increasing the collision pressure by increasing the change in the direction of motion of the liquid.

In addition, the inner wall of the production tank includes a structure in which a plurality of fine protrusions 201 are formed. By forming a plurality of fine protrusions 201 on the inner wall of the production tank, the high pressure water introduced from the pump 100 collides with the fine protrusions 201 to generate a pressure resistance. Due to the pressure resistance generated at this time, the water collided with the fine protrusion 201 increases the pressure. Thereafter, the flow rate of the water with increased pressure due to collision with the fine protrusion 201 is increased, and the water with the different flow rates continues to collide with each other, thereby increasing the pressure, thereby providing a function of generating microbubbles better.

3 is a cross-sectional view showing a modified embodiment of the production chamber 200 of the present invention.

The bending portion 211 of the chamfer 230 according to FIG. 3 is based on a structure in which the outer bending portion 211b and the inner bending portion 211a are bent and extended in the same width while maintaining the same radius of curvature. The production auxiliary part 212 may be further provided at the inner bent portion 211a of the bent portion 211.

The production auxiliary part 212 is provided at the inner bent portion 211a of the bent portion 211 and includes a first rounding section 212a, a second rounding section 212b, and a third rounding section 212c.

The first rounding section 212a is a portion extending in a first radius of curvature from a bending start point of the short side side 220 to a point where it meets an imaginary line extending in the normal direction from the center of the bending portion 211. The second rounding section 212b is the first rounding radius as the second radius of curvature equal to the radius of curvature from the point where it meets the imaginary line among the outer bent portions 211b of the chamfer 230 to the point extending to the long side 210. A portion extending from the end of the section 212a in the direction toward the long side side 210 in the chamfer portion 230. The third rounding section 212c is a portion that is bent at the end of the second rounding section 212b and extends in a third radius of curvature from the chamfer 230 to the end point of bending the long side 210.

 The first rounding section 212a refers to an introduction site for gradually increasing the thickness of the production assistant part 212 while extending from the short side side 220 bending start point.

The second rounding section 212b extends to the long side side 210 at a point where the second rounding section 212a meets the imaginary line among the outer bent portions 211b while being spaced apart from the inner bent portion 211a by the first rounding section 212a. By bending extended to the same radius of curvature to the radius of curvature up to, as a result it is possible to maintain the increased bent thickness spaced apart by the first rounded section 212a.

In other words, the second rounding section 212b is a portion thicker than the start of the first rounding section 212a, thereby causing the pump 100 to be delivered to the first and second rounding sections 212a and 212b. This results in a difference in the transfer distance of the pressure, since the second rounding section 212b is thicker than the first rounding section 212a and consequently the pump pressure is transmitted to the second rounding section 212b before the first rounding section 212a. do. As such, the pressure transmitted to the second rounding section 212b is reflected in the direction of the opposite long side 210 by the inherent shape of the concavely curved second rounding section 212b or the specific region of the opposite long side 210. The reflection force can be converged in the direction toward this. However, since the long side 210 has a longer length than the short side 220, the scene 210 may have a larger probability than the short side 220 due to the control of the curvature of the bent portion. Accordingly, the second rounding section 212b guides the reflecting force generated when the pressure in the pump 100 strikes the chamfer 230 and converges to the opposite side, but the opposite side is relatively longer than the short side 220. To be formed to the long side (210) side.

As such, in the process of controlling the reflection direction in which the pump pressure is reflected, the rate of contact of the water with the inner wall of the production chamber 200 may be increased, thereby providing a base from which micro bubbles may be easily generated.

Furthermore, the pump 100 pressure is transmitted to the relatively thicker second rounding section 212b to combine the structural stability of the production chamber 200 with the function of distributing the pressure applied to the short side 220. The durability can be prevented to prevent a problem that the production chamber 200 is easily broken.

The third rounding section 212c is basically extended to contact the inner bent portion 211a as shown in FIG. 3A, but furthermore, a chamfer treatment so that the inner bent portion 211a and the step are not generated. It is also possible.

The third rounding section 212c has a function of inducing or guiding the above-mentioned reflecting force in the direction of the opposite side short side 220 by causing the second rounding section 212b to be bent convexly unlike the concavely bent. Can be done. That is, unlike the second rounding section 212b, the third rounding section 212c guides the water toward the opposite short side 220 so that the pressure transmitted to the chamfer 230 does not concentrate on the long side 210. Instead, it is properly distributed in the direction of the short side 220, thereby fully utilizing the entire internal space of the production chamber 200, thereby providing a driving force to better generate microbubbles.

In summary, the generation assistant part 212 distributes the pressure generated when the microbubbles collide to the long side 210 to reinforce structural stability and durability of the production chamber 200, as well as second and third roundings. The inductive function of the conscious long side / short side 210,220 side reflecting force by the sections 212b, 212c allows the microcavity generation to be further promoted while utilizing the inner space of the production chamber 200 more broadly. to provide.

Hereinafter, a cleaning method using the micro bubbles generated by the above-described micro bubble generator will be described.

In the cleaning method using a microbubble according to the present invention, generating a microbubble in water through the micro-generating device described above, and generating a washing water by adding a cleaning composition to water in the process of generating the microbubble. And washing the object to be cleaned through the washing water, wherein the cleaning composition comprises 25 to 45% by weight of alkali, which is one of 15 to 35% by weight of surfactant, sodium hydroxide or potassium hydroxide, based on the total weight of the cleaning composition. , 5 to 30% by weight of disinfectant, EDTA 5 to 20% by weight, sodium triphosphate 5 to 20% by weight of the mixture is characterized in that it consists of.

Hereinafter, the cleaning composition which is one component of the washing water will be described in detail.

4 is a conceptual diagram showing a cleaning composition of the present invention, Figure 5 is a flow chart showing a cleaning method using a microbubble of the present invention.

The cleaning composition of the present invention refers to a composition which is mixed with water to form the washing water, and 25 to 45% by weight of alkali, which is one of 15 to 35% by weight of surfactant, sodium hydroxide or potassium hydroxide, based on the total weight of the cleaning composition. , 5 to 30% by weight of disinfectant, EDTA 5 to 20% by weight, sodium triphosphate 5 to 20% by weight of the mixture is characterized in that it consists of.

Such a cleaning composition may be introduced through a separate inlet tube in the process of generating micro bubbles in the production chamber 200 or through an open / close opening formed separately on the production chamber 200.

Here, surfactants are both lipophilic materials having both hydrophilic and hydrophobic structures, and representative examples thereof include soap and detergent. In this case, when the surfactant is added to the water at a predetermined concentration (critical micelle concentration) or more, the hydrophilic surfactant is exposed to the water (outward) to the round to form a micelle (micelle). Conversely, when a certain amount of surfactant is added to the oil, the tail of the hydrophobic surfactant is exposed to the oil (outward) to form a rounded reverse micelle. The conditions under which such micelles are formed depend not only on the concentration but also on the temperature of the solution, pH, and the concentration of other ions present in the solution (ion strength). These surfactants can be dispersed in the form of an emulsion (emulsion) by surrounding the outer surface of the water and oil that can not be mixed with each other and can perform a cleaning function using this property. In the present invention, as the type of the surfactant, sodium lauryl sulfate (SDS), alkyl ether sulfates and alkaline quaternary ammonium salts, alkylpyridinium salts and alkylimidazolinium salts may be used. have. At this time, the alkaline surfactant is effective to remove organic matters such as protein layer, and the acidic surfactant is effective to remove inorganic contamination.

In addition, alkali may help the solubilization and dissolution of the water to remove the contaminants, and may remove the contamination of silica-based organic matter, such as proteins, microbial by-products. Next, the fungicide serves to remove microorganisms, and DBNPA (2.2-Dibromo-3-Nitrilopropi onamaide) may be used.

In addition, EDTA (2-({2- [bis (carboxymethyl) amino] ethyl} (carboxymethyl) amino) acetic acid) can remove metal salt contamination as a chelating agent and sodium triphosphate as a cleaning agent to remove contaminants in water. Emulsification, dispersion and surface treatment can be carried out.

The cleaning composition thus prepared is mixed with the water generated by the microbubble in the production chamber 200, as described above, to be the washing water, and the like, such as dissolution of pollutants and removal of inorganic precipitates and organic matters. You will be able to play a role effectively.

In addition, the cleaning water is delivered to the cleaning object. If the cleaning object is a metal pipe, there is a possibility that the water may be oxidized and corroded by frequent water contact. In order to prevent such a phenomenon, a corrosion inhibitor including 2-mercaptobenzothiazole may be additionally included in the above-described cleaning composition to effectively prevent corrosion of the cleaning object.

Specifically, the anti-corrosive agent is 15 to 30% by weight of the surfactant, 25 to 40% by weight alkali, which is either sodium hydroxide or potassium hydroxide, 5 to 25% by weight fungicide, 5 to 15% by weight EDTA, triphosphate Sodium 5 to 15% by weight, is added in a ratio of 1 to 15% of the preservative, the preparation method of such a preservative can be prepared through the intermediate solution preparation step, the preservative completion step.

First, the intermediate solution preparation step is 10 to 30% by weight of 2-mercaptobenzothiazole, 10 to 30% by weight of nonionic surfactant, 40 to 60% by weight of the solvent relative to the total weight of the total solution, 10,000 to 15,000rpm The process of preparing the intermediate solution by stirring at a rate of.

Here, 2-mercaptobenzothiazole is a material having excellent anti-rusting ability to prevent corrosion of metals, and nonionic surfactants act as emulsifiers and stability of chemical mixing of corrosion inhibitors. It can be maintained and the specific manufacturing method of such a non-ionic surfactant will be described later. In addition, the solvent has a low viscosity, and the above-mentioned 2-mercaptobenzothiazole and a nonionic surfactant are mixed to form an emulsion, and Isopar-G (Isoparaffinic Hydrocarbon Solvent) and tetrachloroethylen are formed. Can be used.

Next, the step of completing the corrosion inhibitor is mixed with 20 to 50% by weight of the intermediate solution, 50 to 80% by weight of the prepolymer resin, and then heated to 40 to 80 ℃ and stirred at a speed of 150 to 450rpm relative to the total weight of the corrosion inhibitor The process of completing it. Here, the prepolymer resin is a resin prepared by mixing a melamine and formaldehyde solution to surround 2-mercaptobenzothiazole in an intermediate solution to prepare a microcapsule-type corrosion inhibitor. Therefore, the prepolymer resin serves as a wall material covering 2-mercaptobenzothiazole, and the microcapsule-shaped anti-corrosion agent thus prepared can prevent corrosion of the object to be cleaned and the material having anti-rust performance is encapsulated. These performances can be reliably lasted longer because they are stacked together.

The aforementioned nonionic surfactants can serve as emulsifiers and maintain the stability of chemical mixing of the preservatives. Such nonionic surfactants include Perfluoromethylhydrogen siloxan, allylpolyether, allylglycidyl ether, and specific manufacturing methods include preparing a first mixed solution, preparing a second mixed solution, and a nonion. It can be prepared through a surfactant completion step.

First, the primary mixed solution preparation step is 30 to 70% by weight of perfluoromethylhydrogen siloxan, 10 to 50% by weight of allylpolyether, allyl glycidyl ether relative to the total weight of the first mixed solution It is a process of preparing a primary mixed solution by mixing the weight%. Specifically, perfluoromethylhydrogen siloxan is a hydrophobic group material, allylpolyether is a hydrophilic group material, allylglycidyl ether plays a role of imparting a binding reactivity between perfluoromethyl hydrogen siloxane and allylpolyether. Do this.

Next, the secondary mixed solution preparation step is a process of preparing a secondary mixed solution by mixing 95 to 99.99% by weight of the primary mixed solution, 0.01 to 5% by weight of chloroplatinic acid relative to the total weight of the second mixed solution. At this time, the mixture is stirred for 5 to 30 minutes, and then the reaction of the primary mixed solution and the chloroplatinic acid is started after 1 to 5 minutes in a 70 to 90 ℃ environment. At this time, the chloroplatinic acid serves as a catalyst to reduce the rate of secondary mixed solution production.

Finally, the nonionic surfactant completion step is a process of completing the nonionic surfactant by cooling the secondary mixed solution at 20 to 30 ° C. The non-ionic surfactant thus prepared serves as an emulsifier and can maintain the stability of chemical mixing of the corrosion inhibitor. When the nonionic surfactant is included in the washing water, the viscosity of the washing water is increased, and the high viscosity washing water can suppress the formation of large bubbles in the existing water and improve the cleaning effect by further increasing the retention time of the microbubbles in water. Can be.

In another embodiment, the adsorbent powder may be additionally included in the cleaning composition of the present invention to remove the odor due to the contaminants and to improve the cleaning effect due to the high adsorption force on the contaminants. Specifically, 10 to 30% by weight of surfactant, 20 to 40% by weight of alkali, which is either sodium hydroxide or potassium hydroxide, 5 to 20% by weight of disinfectant, 1 to 10% by weight of EDTA, 1 to 1% of sodium triphosphate The adsorbent powder may be additionally included in the cleaning composition at a ratio of 10% by weight, 1 to 10% by weight of corrosion inhibitor, 1 to 10% by weight of antioxidant, and 10 to 20% by weight of adsorbent powder.

In addition, the corrosion protection was evaluated after the evaluation step observed the degree of corrosion of the cleaning object due to the cleaning water containing the cleaning composition of the present invention. The smaller the degree of corrosion of the object to be cleaned due to the cleaning composition of the present invention and the commercially available cleaning solution, the closer to very good (5), and the greater the degree of corrosion, the closer to very poor (1).

<Example 1>

A cleaning composition was prepared by mixing 35 g of surfactant, 30 g of sodium hydroxide, 15 g of bactericide, 10 g of EDTA, and 10 g of sodium triphosphate.

Adsorption powder containing activated carbon was prepared.

An anticorrosive comprising 2-mercaptobenzothiazole was prepared.

Next, the cleaning composition further contained an adsorbent powder and a corrosion inhibitor.

<Example 2>

A cleaning composition was prepared in the same manner as in Example 1, except that the cleaning composition did not contain the adsorbent powder.

<Example 3>

A cleaning composition was prepared in the same manner as in Example 1, except that the cleaning composition did not include a corrosion inhibitor.

<Control>

Commercial cleaning liquids.
