Description

Ozone generation injection device and shoulder type ozone disinfection device

The present invention relates to an ozone generation injection device and a shoulder type ozone disinfection device, and in particular, an ozone generation which generates high concentration ozone gas, can be made small and lightweight, and can effectively jet ozone and ozone containing ozone toward an object. The present invention relates to a spray device and a shoulder type ozone disinfection device.

With the aim of safe and reliable food production, there is a need for the sterilization and insecticidal law of pests that do not cause agricultural and agricultural pollution by agricultural chemicals. Ozone has strong oxidizing, bactericidal and insecticidal effects, disappears in a short time, and it is used for sterilization and insecticidal use of pests for agricultural products because ozone does not remain toxic to agricultural products. Is expected.

Ozone (O ₃ ) is disinfected with ozone gas or ozone water alone or in the form of ozone mist (ozone mist) mixed with liquid, because it has strong oxidizing action and effects such as sterilization, deodorization and bleaching. , Deodorizing, decoloring, semiconductor cleaning, etc. When released into the air, ozone in the gaseous state reacts with moisture and organic substances (dust and the like), disappears quickly, and changes to other substances. When ozone reacts with water (H ₂ O), many ozone derivative products (OH radicals, oxygen atom radicals, HO ₂ radicals, etc.) are newly generated, and the bactericidal power of ozone is dramatically enhanced. In particular, the bactericidal activity of OH radicals and O radicals is very high, and has a bactericidal effect next to fluorine (F). However, these highly bactericidal radical species react with surrounding materials and lose their activity in a short time and disappear. The OH radical is said to disappear in a few microseconds. Generally, high concentration ozone gas is generated from oxygen gas by electric discharge. Development of a device that can spray an ozone derivative product generated by the reaction between ozone gas and water instantaneously to a target while maintaining high sterilizing power is an urgent issue in promoting agricultural product production for the purpose of pesticide-free organic cultivation It is.

There is a method of spraying ozone water obtained by mixing ozone with water to agricultural products, but since there is a limit (about 12 ppm with 3% ozone gas) in the solubility of ozone in water, long-time spray is required. The disinfection effect is low, and the cost of disinfection is high due to the large scale of equipment, and the spread to agriculture is limited. That is, the ozone disinfection devices currently used in agriculture are all intended for use in large-scale agriculture, and are mainly methods of spraying ozone water on crops or directly injecting ozone water into soil. There is a limit to disinfected farmland because it is large-scale equipment and expensive and stationary. In addition, a large installation space is required, and furthermore, for example, ozone generated by the ozonizer is finally ejected from the spray nozzle via one or a plurality of storage chambers and a branch pipe, so that the jet nozzle In the part, only ozone water with low ozone concentration was ejected, and it was not possible to obtain desirable sterilization and insecticidal functions.

In order to sterilize and kill agricultural products grown outdoors with ozone, high concentrations of ozone are required to be sprayed in a short time to improve working efficiency, and at the same time, health damage to workers is caused. It is necessary to maintain the ozone concentration in the working environment below the standard value (0.1 ppm) to

In addition, organic farming without pesticides is carried out in small-scale agriculture, house cultivation, mountainous areas, etc., but biological control with chemicals derived from plants (such as chrysanthemum emulsifier etc.) is mainly used for disinfection Is limited. Under such circumstances, development of a small and easy-to-use ozone sterilizer has become desirable at home and abroad in consideration of the topography of cultivated land, cost reduction of disinfection, reduction of labor of workers, etc. .

Conventionally, the devices of

Patent Documents

1 and 2 have been proposed as disinfection devices using ozone.

Japanese Patent Laid-Open No. 2000-316956 JP, 2004-173904, A JP 2003-320278 A

Patent Document 1 discloses an ozone sterilizer that simultaneously sprays two fluids of an ozone-containing gas and a liquid such as water from a spray nozzle to improve the bactericidal activity. In the apparatus of Patent Document 1, the ozone-containing gas generated in the ozone generator 2 (hereinafter referred to as the number in Patent Document 1 in this paragraph No. 0008) is supplied to the spray nozzle 3 through its supply pipe. Since the ozone is generated, it is transported to the tip of the nozzle by a pipe and the concentration drops sharply due to the dissociation of ozone, the recombination with oxygen molecules, and the reaction with impurities. The ozone concentration decreased to the nozzle, and as a result, the bactericidal effect was reduced and the disinfecting function could not maintain the limited or sufficient disinfecting function. On the other hand, in the apparatus of Document 1, ozone gas is pumped through the conduction path of the nozzle body 3a, and the liquid is sucked from the projecting end thereof under negative pressure at the time of ejection to mix the gas and liquid while discharging the nozzle cap 3b. Since the liquid is spouted from the air flow energy, the ozone gas can not be sucked by the ejector effect from the lower part unless the ozone gas is pumped at a high pressure. For this reason, the fluid from the spout is transported at a high speed as a jet stream and diffused to a distant location, so high concentration ozone gas or ozone mist can not be locally jetted locally in a short time, resulting in a sterilizing effect. Reduced and could not effectively disinfect and disinfect pests, bacteria and viruses attached to crops outdoors. Furthermore, in the device of Patent Document 1, since the liquid such as water is sucked from the container and sprayed by the fluid energy of the ozone containing gas, it is necessary to install the liquid container and the spray nozzle in the proximity position. As a result, it is impossible to perform a delicate operation such as injecting ozone gas at a close distance toward the pest of the leaves of the plant to which the pest adheres. Furthermore, a cooling fin is attached to the electrode portion for cooling of the heat generation of the ozone generator 2, and further a cooling fan is required, resulting in a problem that the apparatus is heavy and expensive.

Further, Patent Document 2 dissolves ozone by supplying ozone gas to the mist outlet of the two-fluid nozzle in the mist generated by the two-fluid nozzle, and then the ozone mist is generated by air containing residual ozone that is not dissolved in the mist. Shows an ozone deodorizing device that sprays and sprays on the surface and space to be disinfected and deodorized. This device requires a large flow of air (34 liter / min) to draw water from the water tank with compressed air and eject the mist, so the concentration of ozone ejected from the two-fluid nozzle is large. There is a problem that the bactericidal effect is reduced because it is lowered and transported to a distant place and diffused.

Furthermore, in Patent Document 3, an auxiliary injection port 7 for water mist injection is provided outside the main injection port 6 for ozone mist injection (hereinafter, reference will be made to the number in Patent Document 3 in this paragraph number 0010). There is disclosed a method of atomizing residual ozone which has not been absorbed by the ozone mist in the gas-liquid mixing unit 5. In the method of Patent Document 3, there is a possibility that the liquid may flow back from the gas mixing unit 5 to the gas flow path 2 to supply the high-pressure liquid from the liquid injection port 4. Therefore, the ozonizer is broken to cause dielectric breakdown. As well as causing equipment failure, the concentration of dissolved ozone is low (1 ppm), and there is a problem of reducing the sterilizing effect.

The present invention has been made in view of the above-described conventional problems, and one object thereof is to directly connect a spray nozzle to an ozone generator, spray high concentration ozone gas from a narrow tube of a nozzle portion, disinfect with ozone, deodorize, An object of the present invention is to provide an ozone generation and injection device that produces a bactericidal action. Another object of the present invention is to provide an ozone generation and injection device which is light in weight, small in size, low in price and capable of good operability. In addition, another object of the present invention is to provide an ozone generation and injection apparatus capable of performing a spray operation suitable for an object by changing the spray of a thin tube of a nozzle and the spray mode of liquid according to the object to be disinfected. It is. Furthermore, another object of the present invention is to provide a compact, lightweight and compact-type ozone disinfection apparatus including an ozone generation and injection apparatus.

At this time, the connection member 3 may be detachably connected to the other end 5 b of the discharge tube 2.

Moreover, it is good for the thin tube 32 of the nozzle part 4 to be provided in the inside, and the cover 34 which has a big large opening compared with the flow path diameter of a thin tube is provided.

Further, the thin tube 32 may include an expandable thin tube 40 whose length can be expanded and contracted.

Furthermore, it is preferable that at least one thin tube 48 whose tip projects beyond the position of the opening 34 a of the cover 34 is provided.

Furthermore, the tip of the thin tube 32 is at a position retracted to the back side of the position of the opening 34a of the cover 34, and the tip end of the cover is such that the cross-sectional diameter from the middle side of the cover 34 to the opening 34a gradually decreases. It is preferable that the cross-sectional shape from the side to the opening is formed in an arc shape.

In addition, it is preferable that a reach distance suppressing mechanism 36 is provided which divides the reach or the tip of one or a plurality of thin tubes 32 in the cover 34 into a plurality of branches to suppress the reach of ozone.

Further, a cooling jacket portion 50 for holding the pressurized coolant directly or indirectly in contact with the outer periphery of the discharge tube 2 and a mist nozzle portion directly connected to the cooling jacket portion 50, and arranged in the vicinity of the outer periphery of the thin tube 32 And the mist nozzle part 52 which sprays the cooling fluid from 50 in mist form.

Further, the cooling jacket portion 50 is formed of a cooling pipe 58 wound in a plurality of turns in a spiral in a part or all of the longitudinal direction around the outer periphery of the discharge tube 2, one end of the cooling pipe 58 being a mist nozzle portion 52 It is good to be connected to

Further, according to the present invention, the ozone generation and injection apparatus 1 according to any one of claims 1 to 10, the power supply unit 102, the cooling fluid tank 112 for supplying the cooling fluid to the cooling jacket unit 50, and pumping of the cooling fluid. From a shoulder type ozone disinfection device 90 characterized in that it includes a driving device 100, a power supply unit 102, a coolant tank 112, and a back support frame 114 on which a coolant pumping drive device 100 is mounted. Configured

According to the ozone generation and injection apparatus of the present invention, a discharge tube for generating ozone by applying a high voltage between the electrodes while introducing oxygen or a gas containing oxygen from one end side, and the other end side of the discharge tube are directly connected A connecting member having one or more passages through which ozone generated in the discharge tube passes, and one or a plurality of thin tubes attached to the connecting member in communication with the passage of the connecting member and protruding in the flow direction of ozone And the ozone (O ₃ ) generated and generated in the discharge tube is directed almost directly from the outlet of each capillary toward the object to be disinfected without being reduced in concentration by piping etc. on the way As a result of the injection, high concentration ozone gas can be reliably injected. In addition, since the ozone generator and the nozzle are specifically configured integrally, these are separately configured, and a pump for supplying ozone generated by the ozone generator, a supply pipe, a reservoir, and the like are not required. Contributing to reduction in size, weight and cost. In addition, since ozone is injected from one or a plurality of thin tubes, the object can be reliably injected with a flow of a directional gas.

In addition, the connecting member is detachably connected to the other end of the discharge tube, thereby preparing a connecting member to which plural types of thin tubes, such as length, diameter, and expansion and contraction configurations, are attached. In addition, it is possible to carry out the disinfection operation using the optimum ozone according to the body to be disinfected and the working environment, and it is possible to maintain the promptness of the start and end of the agricultural disinfection operation.

Further, by providing a cover provided so as to wrap the thin tube of the nozzle portion inside and having a large opening larger than the flow passage diameter of the thin tube, it is possible to prevent the worker from inhaling ozone gas directly. , Form a suitable mixture with the water mist after the injection of ozone.

In addition, since the capillary tube is configured to include an expandable capillary whose length can be expanded and contracted, when the jet is to be carried out at a deep place where the ozone jet of the specific object to be disinfected is required, it is carried out in an extended state. In this way, it is possible to ensure that ozone is sprayed and disinfected at a specific disinfecting point. Moreover, the disinfection effect can be exhibited effectively also to the to-be-disinfected object long to a perspective direction by the ozone gas flow of the several steps | distances of the travel distance about the injection direction.

In addition, by providing at least one capillary having a tip projecting beyond the position of the opening of the cover, the ozone gas flow from the capillary has different ozone reach distances, so that a plurality of the jet directions can be obtained. By the ozone gas flow of the reach of the step, the disinfecting effect can be effectively exerted even on the object which is long in the perspective direction.

In addition, the tip of the capillary is at a position retracted to the back side of the position of the opening of the cover, and the cross section from the tip of the cover to the opening so that the cross section diameter from the middle side of the cover to the opening gradually decreases. With the configuration formed in an arc shape, a flow induced to the opening side is formed along the inner wall of the cover, and this flow acts so as to suppress the jet flow from the capillary outlet. The weakened stream is released from the opening of the cover so as to diffuse gently to the surrounding area, and the jet stream jets sufficiently spray the ozone gas onto the object so that the sterilization action by the ozone gas is not limited in a short time. Function can be implemented.

Furthermore, since it has a configuration in which the reach or distance control mechanism is provided, in which the middle or tip of one or a plurality of thin tubes in the cover is branched into a plurality of branches to suppress the reach of ozone, the ozone coming out of the branch pipe The components hit the wall of the cover in the orthogonal direction and hit the wall surface, resulting in reverse flow and turbulence in the whole, so that they flow to the outlet part to prevent straight flow and resist the post-discharge distance. As a result, the ozone gas is not a jet stream but a diffusive flow which spreads slowly, and sufficient ozone gas can be locally and intensively jetted to the body to be disinfected.

Further, a cooling jacket portion for holding the pressurized coolant directly or indirectly in contact with the outer periphery of the discharge tube, and a mist nozzle portion directly connected to the cooling jacket portion, the coolant from the cooling jacket portion disposed in the vicinity of the outer periphery of the thin tube Since the nozzle has a mist nozzle for spraying in the form of mist, the cooling water of the discharge tube can be used as it is as the reaction water for the reaction of ozone as it is. The single pump can reduce the size and weight of the entire apparatus, and simplification of supply piping can achieve cost reduction.

In addition, the cooling jacket portion is formed of a water cooling pipe spirally wound in a plurality of turns around a part or all of the discharge tube in the longitudinal direction, and one end of the water cooling pipe is connected to the mist nozzle portion This is realized specifically by connecting a cooling pipe in which the cooling water of the discharge tube is also used as it is as reaction water for ozone as it is spirally wound around the outer periphery of the discharge tube to the mist nozzle of the nozzle portion. It can.

Further, according to the shoulder type ozone disinfection apparatus of the present invention, the ozone generation and injection apparatus according to any one of claims 1 to 10, a power supply section, and a coolant tank for supplying a coolant to the cooling jacket section. Since it is configured to include one pump carriage for cooling liquid, the power supply unit, the coolant tank, and the pumping drive for cooling liquid, one worker can perform ozone generation injection by one worker. As a result of being able to perform spray operation while moving with the backrest on which the component case is held and the component is arranged as a group of lumps, it is possible to carry out the spraying operation. With the disinfection device of the present invention, it is possible to realize difficult individual and specific disinfection operations by detailed operations and by the operation of one worker.

Hereinafter, an ozone generation injection device and a shoulder type ozone disinfection device according to an embodiment of the present invention will be described with reference to the attached drawings, but the present invention is not limited to only the configuration of the following embodiment. First, the configuration of the ozone generation and injection device will be described. In addition, since the disinfection, the pest control, and the deodorizing function can be simultaneously performed by injecting ozone, hereinafter, in the case of "disinfecting", it is intended to include all the meanings of those.

FIG. 1 is a vertical cross-sectional view of the ozone generation and injection apparatus according to the first embodiment of the present invention. In the figure, the ozone generation and injection apparatus 1 includes a discharge tube 2, a connection member 3, and a nozzle portion 4. And. The discharge tube 2 is a discharge means for generating ozone by applying a high voltage between the electrodes while introducing oxygen or a gas containing oxygen from one end side, and an ozonizer or an ozone generator for generating ozone by so-called silent discharge. Is the same as

In the embodiment, a tube main body 5 comprising a hollow cylindrical tube opened at both ends is provided, and a gap 6 of, for example, about 1 mm (millimeter) is provided in the tube main body with the inner wall of the tube main body 5 The voltage electrode 7 is inserted. The tube main body 5 is a dielectric that generates creeping discharge, and is a container for introducing and generating oxygen as a raw material gas for ozone generation, and in the present embodiment, an alumina (Al ₂ O ₃ ) dielectric pipe is It is used. An oxygen or oxygen-containing ozone source gas is introduced into the space 6 of the tube body 5 and discharged to generate ozone. The tube main body 5 can also be made of a material that can be formed into a tube by a glass tube, plastic or other dielectric material.

In the embodiment, the discharge tube 2 includes the tube body 5 and the high voltage side and the low voltage side electrodes (7, 10) to which an AC high voltage is applied via the tube body. A discharge is generated on the surface of the dielectric by an alternating high voltage applied between the electrodes, and dissociation of the supplied oxygen and reaction due to collision generate ozone. As the creeping discharge type discharge tube according to the embodiment, various attachment configurations of electrodes to the discharge tube may be variously considered, but any discharge of any embodiment as long as it functions in the specific application of the ozone generation and injection apparatus of the present invention. A tube configuration may be used. For example, the dielectric is disposed only on the AC high voltage electrode side, or the dielectric is inserted into both the high voltage electrode and the ground electrode, or the ground electrode is embedded in the dielectric (FIG. 9) See, for example, and those in which a large number of linear electrodes are installed and fixed on the surface of a dielectric. In the present embodiment, for example, a stainless steel screw rod is used for the high voltage electrode 7, and a state in which one end is protruded to the outside by screwing through the joint member 8 sealing the one end side of the pipe main body 5 , And the other end side is inserted and disposed in the tube main body 5. Besides, metal rods or hollow pipes can also be used. A gap 6 as a discharge gap is formed between the outer periphery of the portion of the high voltage electrode 7 inserted in the tube main body 5 and the inner wall of the tube main body 5 by a support means (not shown). The high voltage electrode 7 is a high voltage side internal electrode disposed in the tube main body 5, and in the embodiment, the outer surface is formed into a screw shape having, for example, sharp peaks and valleys. Thereby, the discharge can be started at a low voltage and the discharge can be maintained. A ground electrode 10 is closely attached to the outer periphery of the tube body 5. The ground electrode is made of a conductive metal and is formed by depositing a copper foil in the present embodiment. A high frequency AC high voltage (for example, 10-15 kHz, 4-10 kV) is applied between the high voltage electrode 7 and the ground electrode 10, and oxygen or an oxygen-containing gas is introduced into the air gap 6 of the tube body. A creeping discharge is generated on the surface of the dielectric as a tube body. The high frequency high voltage can be supplied by boosting the commercial power supply, but for example, the disinfection using the ozone generation injection device 1 by supplying it through an inverter (not shown) using a semiconductor element of a small and lightweight member, Deodorizing and compacting the whole sterilizer contributes to the portability of the whole equipment.

The joint member 8 fitted to the one end side 5a of the pipe main body 5 is provided with a passage 12 communicating with the gap 6 which is a gap, and the passage 12 is connected with a gas port (not shown) via the connection port 14 Is connected to supply oxygen or a gas containing oxygen.

The other end of the tube body 5 is open, and a space 20 is provided between the tip of the inserted high voltage electrode 7 and the tip of the tube body 5.

The connecting member 3 is a connecting means directly connected to the other end of the discharge tube 2 to allow ozone generated in the discharge tube to pass therethrough and release the ozone to the outside, and in particular, the connecting member 3 is a discharge tube The ozone directly connected to 2 is connected to the nozzle 4 directly on the way without passing through piping, a reservoir or the like on the way. In the embodiment, the connecting member 3 has a connecting portion 22 connected to the other end 5 b of the tube main body 5 and is provided with one or a plurality of passage paths 24 through which ozone is allowed to pass on the nozzle portion 4 side. Specifically, the connecting member 3 is formed of a Teflon (registered trademark) material or a cylindrical body of a ceramic, and has a connecting portion 22 having a fitting hole 26 for detachably receiving one end side of the tube main body There is. Then, the inside of the connection member 3 and the pipe main body 5 is connected in an airtight state by the O-ring 30 held by the holding portion 28 disposed on the inlet side of the fitting hole 26. One or more passages 24 are formed along the flow direction of the ozone in communication with the bottom of the fitting hole 26 in the opposite thick part of the connection member 3 into which the tube main body 5 has been inserted. The ozone generated in the above is supplied to the nozzle portion 4 via the space 20 and the passage 24.

In the embodiment, the connection member 3 is connected to the other end 5b of the discharge tube 2 so as to be freely fitted and detached, and the nozzle portion 4 can be easily made according to the number of thin tubes of the body to be disinfected It is exchangeable.

In FIG. 1, the nozzle portion 4 includes one or a plurality of thin tubes 32 attached to the connection member 3 so as to be in communication with the passage 24 of the connection member 3 and protruding in the flow direction F of ozone. In the embodiment, one end side base of the thin tube 32 is connected to the passage outlet 24 a portion of the connection member 3. Thereby, the connection member 3 and the thin tube 32 are integrated. For this reason, the nozzle part 4 can be replaced | exchanged integrally with a connection member. The connection member 3 and each capillary can be made detachable. Each thin tube 32 is made of, for example, an ozone resistant metal or synthetic resin pipe (for example, stainless steel or Teflon (registered trademark) material pipe) having a diameter of about 1 mm to several mm and a length of about 3 cm (centimeter) It communicates with the passage 24 outlet 24 a of the connection member 3. The thin tube 32 is formed so as to extend long in the flow direction of ozone from the passage outlet 24a of the connection member 3 so as to have a directivity and jet force directed in the direction set by the thin tube configuration. There is. The tip outlet 32a of the thin tube 32 is not provided with a jet port such as another jet body by means of a separate body, etc. and is not provided, and is suddenly opened to the atmosphere from the tip outlet 32a. Further, the ozone gas jetted from each capillary is jetted at almost the same low pressure (for example, 1 L / min) as the atmosphere. For example, even if a hand is put on the tip end outlet 32a, the wind pressure is hardly felt. Therefore, high concentration ozone gas can be stably injected from the narrow tube. The thin tubes 32 may be integrally formed on the connection member 3 or may be attached and connected one by one, or may be detachably attached one by one. Furthermore, in the present embodiment, the thin tube 32 can be bent by the operation of a human finger or the like, and has flexibility to such an extent that the shape can be maintained in the bent state. By this, the injection direction of each thin tube can be set individually, and the injection speed and the injection amount per time can be controlled. Further, the thin tubes 32 are arranged to converge so as to be arranged within a certain area, for example, so that their outlets are arranged in a circle whose diameter is about the diameter of the discharge tube 2. The number of thin tubes may be one, but in order to exert the function of ozone effectively, two or more to several tens, particularly about 3 to 10 are preferable. In the present embodiment, a total of five thin tubes 32 are provided at a central portion and a 90 ° apart position around the central portion (see FIG. 1 b). As a result, ozone (O ₃ ) generated and generated in the discharge tube 2 is injected almost directly from each capillary outlet 32 a toward the object to be disinfected without being reduced in concentration by piping etc. on the way, and ozone gas of high concentration is It can be injected reliably. In the embodiment, the ozone gas is injected from each of the thin tubes 32 at the pressure supplied from the oxygen generator, and the injection pressure is injected as a low pressure gas. Moreover, since it is a thin tube structure which protrudingly provided from the wall surface of the connection member 3 and the front-end | tip open | releases to air | atmosphere, the back flow to the ozone generator side is not produced. Tubular device The device of the present invention can be said to be an integrated ozone generator and injection nozzle type device.

In the present embodiment, a cover 34 is further provided so as to wrap the thin tube 32 of the nozzle portion 4 inside, and a cover 34 having a large large opening compared to the flow passage diameter of the thin tube is provided. The cover 34 is a mist shield cover that shields over the stroke length to the outlet portion of the thin tube 32 so that liquid mist and ozone from the mist nozzle portion described later arranged concentrically on the outer periphery of the thin tube 32 do not mix. The disinfection and deodorizing effects by high concentration ozone can be efficiently sprayed by the operator in consideration of the angle and the distance of the nozzle portion with respect to the body to be disinfected. Further, by covering the inner thin tube 32 with the cover 34, the function of preventing the backflow of the liquid to the discharge tube side directly connected to the thin tube can be made perfect. The cover 34 may be manufactured integrally with the connection member 3 or may be detachably attached to the connection member 3. The cover 34 is formed in a bag shape so as to extend from the connection portion with the connection member 3 to one side and wrap the thin tube 32 inside, and a barrel shape or a barrel to gradually reduce the opening from the middle portion to the tip end side. It has a spindle shape. The shape of the cover may be an arc shape in cross section from the base side which is a connection portion with the connection member 3 to the tip end side having an opening as shown in FIG. It may be formed to reduce the opening gradually from the close position (see FIG. 8). Also, the middle portion may be formed in a wave shape. Further, in FIGS. 1 and 2, the tip of each thin tube 32 is set at a position retracted to the back side of the position of the opening 34 a of the cover 34. As a result, when ozone gas is jetted from the capillary outlet 32a, a flow k is formed along the inner wall of the cover 34 and attracted to the opening 34a, and this flow acts to suppress the jet flow from the capillary outlet 32a. The weakened stream is discharged from the opening 34a of the cover so as to diffuse to the surrounding area, and the jet stream jets sufficiently spray the ozone gas onto the body to be disinfected so that the sterilization action by the ozone gas is not limited in a short time. Function can be implemented. Further, by forming the cover 34 in a barrel or spindle shape so as to gradually reduce the opening on the injection side from the middle portion to the tip end side, external air is less likely to intrude into the cover from the outside, whereby ozone concentration is reduced. Make it difficult to cause a drop.

3 and 4 show other examples 44B and 44C of the nozzle portion 4. The entire shape of the cover 34 in the nozzle portion 44B of FIG. 3 is the same as that of FIG. 1 in the shape of a circular arc in cross section with a curved curvilinear cover shape with a central portion bulging and both end sides gradually decreasing in cross section opening. Alternatively, it is formed in a spindle shape. The nozzle portion 44B is provided with a reach distance suppression mechanism 36 which branches the middle or tip of one or a plurality of thin tubes in the cover 34 into a plurality of branches to suppress the reach of ozone. In the nozzle portion 44B of FIG. 3, the tubes branch in three directions of one right capillary and two right

angle branch pipes

38a and 38b and one straight branch pipe 38c in the vertical direction. The ozone coming out of the two right

angle branch pipes

38a, 38b impinges on the inner wall of the cover 34 in the orthogonal direction and strikes the wall surface to become a reverse flow l, and the whole becomes a turbulent flow q. Therefore, the turbulent flow q flows to the outlet portion of the straight branch pipe 38c, and the straight flow is impeded to resist and limit the reach after discharge. Therefore, the ozone gas coming out of the cover opening 34a is not a jet stream but a diffusion stream which spreads slowly, so that sufficient ozone gas can be locally and intensively jetted to the body to be disinfected. In the example of FIG. 3, the flow from the right-

angled branch pipes

38a and 38b actively acts to suppress the injection flow of the straight branch pipe 38c. The low pressure ozone gas flow and the formation of the slow diffusive flow due to the cover 34 configuration work in a superimposed manner.

Furthermore, in the nozzle portion 44C of FIG. 4, the capillary tube 32 includes an expandable capillary tube 40 whose length can be expanded and contracted. In the nozzle portion 44C of FIG. 4, for example, a telescopic thin tube 40 is formed of a main thin tube 41a and a main thin tube 41a in a double cylindrical shape and a sliding thin tube 41b slidable with a certain amount of frictional force. There is. The sliding thin tube 41b slides in the longitudinal direction of the tube to a fixed position where it does not get out of the main thin tube 41a, and is locked by a frictional force at an arbitrary position. The overall length of the capillary can be varied thereby. The telescopic thin tube 40 may be configured for only a part of the plurality of thin tubes. By providing the expandable capillary tube 40, when spraying to a deep place where ozone spraying is necessary, such as a specific object to be disinfected, ozone can be reliably sprayed and disinfected at a specific disinfecting location by performing in a stretched state be able to.

In FIG. 5, in the nozzle portion 46A, five thin tubes 32 are provided in the barrel or spindle cover 34 as in FIGS. 1 to 4 with one end connected to the connecting member 3 with the flow direction of ozone as the longitudinal direction. And is converged within the cover 34. The nozzle portion 46A is provided with at least one projecting thin tube 48a whose tip projects from the position of the opening 34a of the cover 34. In the nozzle portion 46A, at least two projecting thin tubes 48a having different projecting lengths from the opening 34a are provided with the tip projecting from the opening 34a. In addition, the other thin tubes 34 are provided such that the tip thereof is at a position retracted to the back side of the opening 34 a. In this nozzle portion 46A, since ozone gas flows having different reaching distances of ozone gas jetted from the thin tube, it is possible to effectively disinfect even an object to be disinfected which is long in the far and near direction by ozone gas flows of the reaching distances of plural stages in the jetting direction. It can be effective.

Further, in the nozzle portion 46B of FIG. 6, five thin tubes 32 are connected at one end to the connecting member 3 with the flow direction of ozone as the longitudinal direction in the barrel or spindle shaped cover 34 as in FIGS. The thin tube 32 of the nozzle portion 46B includes at least one telescopic thin tube 40 whose length can be extended and contracted. Further, at least one of these expandable capillaries is provided with a tip projecting from the position of the opening 34 a of the cover 34. A telescopic thin tube 40 is formed of a main thin tube 41 a and a thin thin tube 41 b connected to the main thin tube 41 a in a double cylindrical shape and slidable with a certain amount of frictional force. The sliding thin tube 41b slides in the longitudinal direction of the tube to a fixed position where it does not get out of the main thin tube 41a, and is locked by a frictional force at an arbitrary position. The telescopic thin tube 40 may be configured for only a part of the plurality of thin tubes. Also in the nozzle portion 46B, since the ozone gas flow is different in the reach distance of the ozone gas jetted from the thin tube, the ozone gas flow of the reach distance of plural stages in the jet direction effectively disinfects the object to be disinfected long in the perspective direction It is possible to exert an effect, but in particular, it is possible to disinfect the object to be disinfected more effectively in the case of spraying in a deep place where ozone spraying is necessary in the far and near direction by the expansion capillary 40 whose tip protrudes from the position of the opening 34a of the cover 34 It can be effective.

Furthermore, in the nozzle portion 46C of FIG. 7, five thin tubes 32 are connected at one end to the connection member 3 with the flow direction of ozone as the longitudinal direction in the barrel or spindle shaped cover 34 as in FIGS.

It is formed. In the nozzle portion 46C of FIG. 7, a reach distance suppressing mechanism 36 is provided which branches the middle or tip of one or a plurality of thin tubes in the cover 34 into a plurality of branches to suppress the reach of ozone. In the nozzle portion 46C of FIG. 7, the tubes are branched in two directions of two right angle branch tubes 49a and 49b in the vertical direction from the tip of the thin tube 49 having the tip position on the back side of the opening 34a of the cover 34. . The ozone coming out of the two right angle branch pipes 49a, 49b impinges on the inner wall of the cover 34 in the orthogonal direction, strikes the wall surface and becomes a reverse flow, and the whole becomes turbulent. Therefore, this turbulent flow flows to the opening 34 a side of the cover 34 to perform the function of suppressing the reaching distance of the linear flow from other thin tubes (not shown), and the gentle flow from the opening 34 a causes the outside of the cover 34. leak. In the nozzle portion 46C, the ozone gas coming out of the cover opening 34a can simultaneously jet the jet stream and the diffusive stream spreading gently, so that sufficient ozone gas can be localized locally also in the perspective direction and the three-dimensional spreading direction. And it can be made to inject with respect to a target object intensively.

The mist nozzle unit 52 is directly connected to the cooling jacket unit 50 and is disposed in the vicinity of the outer periphery of the thin tube 32 to spray the liquid coolant from the cooling jacket unit 50 in the form of a mist and spraying it in the same flow direction as the ozone gas. In the embodiment, as described above, for example, water is atomized to spray the water mist S in the outer peripheral portion of the thin tube 32 in the embodiment. Specifically, a nozzle holding portion 66 enlarged from the covering portion of the cooling jacket portion is provided on the other end 5 b side of the cylindrical casing 54, and the flow direction end face of ozone gas in the nozzle holding portion 66 The mist nozzle 68 is concentrically arranged on the outside of the outer periphery of the arrangement location of the thin tube 32 by exposing the outlets of the many fine holes 68a. In the embodiment, as shown in FIG. 1 (b), four nozzle elements 69 are arranged at positions separated by approximately 90 degrees from each other on the outer side of the cover 34 which encloses the thin tube 32, and each is a water mist Inject the Furthermore, in this embodiment, the position where the mist nozzle 68 is disposed is at the outer peripheral position of the connection member 3 supporting the cover 34 and at a position retracted from the cover 34 in the ozone flow direction.

The liquid mist is jetted from the As a result, the cooling water of the discharge tube can be used as it is as the reaction water for the reaction of ozone as it is, for example, the supply source of the cooling water and the mist water and the pump for driving can be one to reduce the size and weight of the entire apparatus. At the same time, cost reduction can be achieved by simplifying the supply piping. Further, in the present embodiment, since low pressure water is supplied to the liquid (water) supplied to the mist nozzle 68, it is possible to prevent the liquid backflow from the thin tube 32 to the ozone generating means side.

The liquid supplied to the mist nozzle 68 for generating the liquid (water) mist does not necessarily need to use the liquid supplied from the cooling jacket portion 50 for cooling the discharge tube 2. Liquid may be supplied to the mist nozzle 68 to generate liquid mist. Further, the cooling mechanism is not limited to the cooling of the discharge tube by the liquid, and may be provided with a cooling mechanism by air cooling such as a cooling fan. Furthermore, the cooling mechanism itself may not be provided as long as the discharge tube can be configured so as not to cause decomposition of ozone generated by setting conditions.

Further, water is supplied to the cooling pipe 58 through a liquid supply pipe from a pumping drive device such as a pump (not shown).

When a high frequency AC high voltage is applied between the high voltage electrode 7 of the discharge tube and the ground electrode 10, ozone is generated by the dissociation of oxygen molecules and the collision of oxygen atoms, oxygen molecules, and three bodies by a large number of pulsed microdischarges. Is generated. The ozone flows in the direction of the arrow F from right to left in FIG. 1 by the pressure of the oxygen generator, and each capillary passes through the plurality of passages 24 of the connecting member 3 via the space 20 at the other end of the tube body. The high concentration ozone is injected from 32. At this time, since the plurality of thin tubes 32 converge and are provided with the same direction as the flow direction of ozone as the longitudinal direction, ozone is jetted from the small point-like small tube outlets in a gentle low speed flow. During this time, the discharge tube generated by the discharge is cooled by the water supplied into the cooling pipe 58 spirally wound in contact with the ground electrode 10 on the outer surface side of the tube body. Furthermore, the water in the cooling pipe 58 is branched to each mist nozzle 68 via the distribution pipe 70 of the nozzle holding portion 66, and from the outlet of each fine hole 68a to the outer periphery of the capillary, that is, the cover 34, the area of the capillary outlet Is sprayed concentrically with water as a water mist. The ozone sprayed from the capillary is sprayed or sprayed toward the object to be disinfected together with the water mist sprayed outside the area of the outlet of the capillary. At this time, a liquid mist having a particle diameter of about 80 μm to 100 μm spreads immediately in front of the device 1, and furthermore, ozone is jetted to the body to be disinfected in a state where ozone is gently dispersed.

By variously changing the shape of the cover 34, and the attachment aspect and structure of the thin tube 32, it is possible to perform the spraying operation according to the state of the body to be disinfected. For example, as shown in FIGS. 3 and 7, the middle or tip of one or a plurality of thin tubes is branched into a plurality to be directly applied to the inner wall of the cover 34 to produce a reverse flow to make the whole turbulent and reach distance Form a suppression mechanism. This turbulent flow generates a resistance component of straight flow, and injects it outside the cover as a diffusive flow that spreads gently while maintaining high concentration ozone while preventing the inflow of external air to the back side and the mixing with ozone, Sufficient ozone gas can be injected locally and intensively to the object to be disinfected.

Further, as shown in FIGS. 4 and 6, by making it possible to change the entire length of the thin tube as a configuration in which each thin tube itself can expand and contract, sufficient ozone injection can be achieved when injecting to a portion having irregularities. Is possible.

Further, as shown in FIG. 5 to FIG. 7, when the projecting thin tube 48a which protrudes from the position of the opening 34a of the cover 34 is provided, it is possible to inject ozone gas having different reaching distances of ozone gas injected from the thin tube. The disinfection operation can be effectively performed even on a long object in the perspective direction.
