Description

  The present invention relates to an ozone generating / injecting apparatus and a backpack-type ozone disinfecting apparatus, and in particular, ozone generation capable of generating high-concentration ozone gas, making it small and light and effectively injecting ozone and mist containing ozone toward an object. The present invention relates to an injection device and a backpack-type ozone disinfection device.

  Aiming for safe and reliable food production, there is a need for a method for disinfecting and killing pests that does not cause agricultural pollution or environmental pollution by agricultural chemicals. Ozone has a strong oxidizing action, bactericidal and insecticidal effect, disappears in a short time, and does not leave toxicity to agricultural products that have been treated with ozone. Is expected.

Ozone (O ₃ ) has a strong oxidizing action and has effects such as sterilization, deodorization, and bleaching, so it can be disinfected by ozone gas or ozone water alone or in the form of ozone mist (ozone mist) mixed with liquid. It is used for deodorization, decolorization, and semiconductor cleaning. When ozone in a gaseous state is released into the air, it reacts with moisture and organic matter (such as dust) and quickly disappears to change to another substance. When ozone reacts with water (H ₂ O), many ozone-derived products (OH radicals, oxygen atom radicals, HO ₂ radicals, etc.) are newly born, and the sterilizing power of ozone is dramatically increased. In particular, the sterilizing power of OH radicals and O radicals is very high and has a sterilizing effect next to fluorine (F). However, these radical species having strong bactericidal activity react with surrounding substances, lose their active power in a short time and disappear. OH radicals are 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 instantly spray ozone-derived products generated by the reaction of ozone gas and water onto the target while maintaining high bactericidal activity It is.

  There is a method of spraying ozone water obtained by mixing ozone with water on agricultural products, but since there is a limit to the solubility of ozone in water (about 12 ppm with 3% ozone gas), spraying for a long time is required. The disinfection effect is low, and the cost for disinfection increases due to the large equipment, and the spread to agriculture is limited. In other words, all of the ozone disinfection devices currently used in agriculture are intended for use in large-scale agriculture, and mainly used to spray ozone water onto crops or inject ozone water directly into the soil. In addition, because it is a large-scale facility, is expensive, and is a stationary type, there are restrictions on disinfecting farmland. Further, a large installation space is required. Further, for example, ozone generated by an ozonizer is finally ejected from a spray nozzle through one or a plurality of storage chambers and branch pipes. Only ozone water with a low ozone concentration was ejected in the area, and the desired sterilization and insecticidal functions could not be obtained.

  In order to sterilize and kill agricultural products cultivated outdoors with ozone, it is required to apply high-concentration ozone within a short period of time to improve work efficiency, and at the same time damage health to workers In order to suppress this, it is necessary to maintain the ozone concentration in the working environment below the reference value (0.1 ppm).

In addition, organic farming that does not use agricultural chemicals is carried out in small-scale farming, house cultivation, mountainous areas, etc., but biocidal control with plant-derived chemicals (such as insecticidal chrysanthemum emulsifiers) is mainly used for disinfection. Is limited. Under such circumstances, the development of a small and easy-to-operate ozone sterilizer that takes into account the terrain of the cultivated land, the cost of disinfection, the labor reduction of workers, and the like has come to be desired at home and abroad. .
Conventionally, the apparatus of patent document 1, 2 is proposed as a disinfection apparatus by ozone.

JP 2000-316956 A JP 2004-173904 A JP 2003-320278 A

  Patent Document 1 discloses an ozone sterilization apparatus that simultaneously sprays two fluids such as an ozone-containing gas and water from a spray nozzle to improve sterilization power. In the apparatus of Patent Document 1, the ozone-containing gas generated in the ozone generator 2 (hereinafter, the number in Patent Document 1 is referred to in this paragraph number 0008) is supplied to the spray nozzle 3 through the supply pipe. Therefore, after ozone generation, the concentration rapidly decreases due to ozone dissociation, recombination with oxygen molecules, and reaction with impurities while being transported to the nozzle tip by a pipe, for example, about 50% at the nozzle tip. The ozone concentration decreased until the nozzle, and as a result, the bactericidal effect was reduced, and the disinfecting function could not be limited or sufficient. On the other hand, in the apparatus of Literature 1, ozone gas is pumped through the conduction path of the nozzle body 3a, and the nozzle end of the nozzle cap 3b is sucked from the projecting end portion with a negative pressure at the time of jetting to mix gas and liquid. Since the liquid is pumped from the air flow energy 36, the liquid cannot be sucked from the lower part by the ejector effect unless the ozone gas is pumped at a high pressure. For this reason, since the fluid from the jet outlet is carried away as a jet stream at a high speed and diffused, high concentration ozone gas or ozone mist cannot be locally concentrated in a short time, and the sterilization effect It was not possible to effectively sterilize and disinfect pests, bacteria and viruses attached to outdoor crops. Furthermore, in the apparatus of Patent Document 1, since liquid such as water is sucked and sprayed from the container with the fluid energy of the ozone-containing gas, it is necessary to install the liquid container and the spray nozzle in a close position, and the spray nozzle portion is heavy. This makes it difficult to perform subtle operations such as injecting ozone gas at a close distance toward the pests on the leaves of plants with pests attached to the nozzle injection port. Further, there is a drawback that a cooling fin is attached to the electrode portion for cooling the heat generated by the ozone generator 2 and a cooling fan is required, which increases the weight of the device and increases the cost.

  Further, Patent Document 2 discloses that ozone mist is generated by mist generated by a two-fluid nozzle by supplying ozone gas to a mist outlet of the two-fluid nozzle and then containing residual ozone that does not dissolve in the mist. The ozone deodorizing apparatus which sprays on the surface and space to be sterilized / deodorized is shown. In this device, a large amount of air (34 liters / min) is required to suck the water in the water tank with compressed air and eject the mist, which greatly increases the concentration of ozone ejected from the two-fluid nozzle. In addition, there is a problem that the bactericidal effect is reduced due to being carried away and diffusing.

  Further, in Patent Document 3, an auxiliary injection port 7 for water mist injection is provided outside a main injection port 6 for ozone fog injection (hereinafter, the number in Patent Document 3 is referred to in this paragraph number 0010). And the method of atomizing the residual ozone which was not absorbed by ozone mist in the gas-liquid mixing part 5 is disclosed. In the method of Patent Document 3, there is a risk that the liquid flows backward from the gas mixing section 5 to the gas flow path 2 in order to supply a high-pressure liquid from the liquid inlet 4, and thus the ozone generator is damaged and dielectric breakdown occurs. As a result, the concentration of dissolved ozone is lowered (1 ppm) and the sterilizing effect is lowered.

  The present invention has been made in view of the above-described conventional problems, and one of its purposes is to directly connect a spray nozzle to an ozone generator and spray high-concentration ozone gas from a narrow tube of the nozzle portion to disinfect, deodorize with ozone, An object of the present invention is to provide an ozone generating / injecting apparatus that produces a sterilizing action. Another object of the present invention is to provide an ozone generating / injecting apparatus that is light and small in size and can be operated at a low cost. Another object of the present invention is to provide an ozone generating and ejecting apparatus capable of performing a spraying operation suitable for an object by changing the spraying state of a thin tube of a nozzle portion or the spraying state of a liquid according to the disinfecting object. There is. Furthermore, another object of the present invention is to provide an ozone disinfection device having a backpack shape that includes an ozone generating / injecting device and is reduced in size and weight.

In order to solve the above problems, the present invention provides a discharge tube 2 that generates ozone by applying a high voltage between the electrodes 7 and 10 while introducing oxygen or a gas containing oxygen from one end side 5a, and other discharge tubes. The connecting member 3 having one or a plurality of passages 24 directly connected to the end side 5b through which ozone generated in the discharge tube passes, and the flow direction of ozone attached to the connecting member in communication with the passages 24 of the connecting member 3 saw including a nozzle portion 4, a containing one or more capillaries 32 projecting from the cover 34 with a large large opening tubules 32 of the nozzle portion 4 as compared to the passage diameter of the capillary is provided so as to enclose the inner side The ozone generation and injection device 1 is provided .

  The narrow tube 32 may include a telescopic tube 40 whose length can be expanded and contracted.

  Furthermore, it is preferable that at least one narrow tube 48 whose tip protrudes from the position of the opening 34a of the cover 34 is provided.

  Further, the tip of the narrow tube 32 is in a position retracted to the back side from the position of the opening 34a of the cover 34, and the tip side of the cover so that the cross-sectional diameter from the middle side of the cover 34 to the opening 34a gradually decreases. It is good to form so that the cross-sectional shape applied to the opening from may become circular arc shape.

  In addition, it is preferable to provide a reach distance suppression mechanism 36 that suppresses the reach distance of ozone by branching the middle or tip of one or more thin tubes 32 in the cover 34 into a plurality of branches.

  Also, a cooling jacket portion 50 that directly or indirectly contacts the outer periphery of the discharge tube 2 and holds the pumped coolant, and a mist nozzle portion that is directly connected to the cooling jacket portion 50. The cooling jacket portion is disposed near the outer periphery of the thin tube 32. It is good to have the mist nozzle part 52 which sprays the cooling fluid from 50 in mist form.

  The cooling jacket portion 50 is composed of a cooling pipe 58 spirally wound around the outer periphery of the discharge tube 2 over a part or all of the longitudinal direction, and one end of the cooling pipe 58 is a mist nozzle portion 52. It is good to be connected to.

The connecting member 3 is preferably detachably connected to the other end 5b of the discharge tube 2.

Further, the present invention relates to the ozone generation / injection device 1 according to claim 6 or 7 , at least the power supply unit 102, the coolant tank 112 that supplies the coolant to the cooling jacket portion 50, and the coolant pumping drive device 100. The power supply unit 102, the coolant tank 112, and the one unit for carrying the coolant pumping device 100 are mounted on a backpack 114.

According to the ozone generation and injection apparatus of the present invention, a discharge tube that generates ozone by applying high voltage between the electrodes while introducing oxygen or a gas containing oxygen from one end side is directly connected to the other end side of the discharge tube. A connecting member having one or a plurality of passages through which ozone generated in the discharge tube passes, and one or a plurality of capillaries communicating with the passages of the connecting member and attached to the connecting member and projecting in the direction of ozone flow Therefore, ozone (O ₃ ) generated and generated in the discharge tube does not decrease in concentration in the middle of the pipe, and is directed from the outlet of each narrow tube to the disinfectant as it is. 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 as a single unit, they are configured separately and do not require ozone pumps, supply pipes, reservoirs, etc. generated by the ozone generator. Contributes to small size, light weight, and low cost. Moreover, since ozone is injected from one or a plurality of thin tubes, it can be reliably injected to the object to be disinfected with a gas flow having good directivity.

  In addition, by connecting the connecting member to the other end of the discharge tube in a detachable manner, by preparing a connecting member to which a plurality of types of thin tubes such as length, diameter, and expansion / contraction configuration are attached respectively. In addition, it is possible to perform the disinfection work using the optimum ozone according to the body to be disinfected and the work environment, and it is possible to maintain the quickness of the start and end of the agricultural disinfection work.

  In addition, by providing a cover provided so as to wrap the narrow tube of the nozzle portion and having a large opening compared to the flow path diameter of the narrow tube, it is possible to prevent the operator from inhaling ozone gas directly. An appropriate mixed state with water mist after ozone injection can be formed.

  In addition, since the narrow tube includes a telescopic tube whose length can be expanded and contracted, when injecting into a deep part where ozone injection of a specific disinfectant is necessary, it is performed in an expanded state. Thus, it is possible to reliably disinfect by disinfecting a specific disinfecting portion with ozone. Moreover, the disinfection effect can be effectively obtained even for a disinfectant that is long in the perspective direction by the ozone gas flow at a plurality of reach distances in the injection direction.

  In addition, since at least one narrow tube having a tip protruding from the position of the opening of the cover is provided, the ozone gas flows ejected from the narrow tube have different ozone gas flows. The ozone gas flow at the reach of the step can effectively disinfect even the object to be disinfected which is long in the perspective direction.

  In addition, the tip of the narrow tube is in a position retracted to the back side from the position of the cover opening, and the cross section from the cover tip side to the opening so that the cross-sectional diameter from the middle side of the cover to the opening gradually decreases. By adopting a configuration in which the shape is formed in an arc shape, a flow attracted to the opening side is formed along the inner wall of the cover, and this flow acts to suppress the jet flow from the narrow tube outlet. The weakened flow is released so as to diffuse gently from the opening of the cover to the surroundings, and ozone gas is sufficiently jetted to the disinfected body so that the sterilization effect by ozone gas is not limited in a short time by jet jet Function.

  Furthermore, since the structure is provided with a reach distance suppression mechanism that suppresses the reach distance of ozone by branching the middle or tip of one or more narrow tubes in the cover into a plurality of branches, the ozone emitted from the branch pipe Hits the inner wall of the cover in an orthogonal direction, hits the wall surface and becomes a reversal flow and becomes turbulent as a whole. As a result, they flow to the outlet portion, obstruct the straight flow and become a resistance to suppress the reach distance after discharge. As a result, the ozone gas becomes a diffused flow that spreads gently instead of a jet stream, and sufficient ozone gas can be locally and intensively injected onto the object to be disinfected.

  A cooling jacket portion that holds the pumped coolant directly or indirectly in contact with the outer periphery of the discharge tube, and a mist nozzle portion that is directly connected to the cooling jacket portion. The mist nozzle part for spraying the mist in the form of a mist, so that the cooling water of the discharge tube can be used as ozone reaction water as it is. For example, the cooling water and mist water supply source or driving This makes it possible to reduce the size and weight of the entire apparatus, and to reduce the cost by simplifying the supply piping.

  Further, the cooling jacket portion is composed of a water-cooled pipe wound in a spiral manner over a part or all of the longitudinal direction on the outer periphery of the discharge tube, and one end of the water-cooled pipe is connected to the mist nozzle portion. By using the cooling pipe that is used as the ozone reaction water as it is, the cooling pipe spirally wound around the outer circumference of the discharge pipe is connected to the mist nozzle of the nozzle section to achieve this specifically. Can do.

Moreover, according to the backpack type ozone disinfection device of the present invention, the ozone generating / injecting device according to claim 6 , at least a power supply unit, a coolant tank supplying coolant to the cooling jacket, and pumping of coolant Since it has a configuration including a drive unit, a power supply unit, a coolant tank, and a single carrier frame on which a coolant pumping drive device is mounted, the housing of the ozone generating and ejecting apparatus can be operated by a single worker. As a result of being able to perform spraying operation while moving the backrest with the back mounted on the back with the component equipment arranged as a lump assembly, for example, between stationary and disinfecting vegetables Difficult individual and concrete disinfection work can be realized by fine operation and by the work of one worker.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an ozone generating / injecting apparatus and a backpack-type ozone disinfecting apparatus according to embodiments of the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to the configurations of the following embodiments. First, the configuration of the ozone generation and injection device will be described. In addition, since disinfection, pest control, and a deodorizing function can be performed at the same time by spraying ozone, the term “disinfection” includes all the meanings hereinafter.

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

In the embodiment, a tube body 5 composed of a hollow cylindrical tube having both ends opened is provided, and a gap 6 of, for example, about 1 mm (millimeters) is provided between the tube body 5 and the inner wall of the tube body 5 to increase the height from one end side. A voltage electrode 7 is inserted. The tube 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. In this embodiment, an alumina (Al ₂ O ₃ ) dielectric pipe is used. It is used. Oxygen or an ozone raw material gas containing oxygen is introduced into the gap 6 of the tube body 5 and discharged to generate ozone. In addition, the tube body 5 can be made of a material that can be formed into a tubular tube using a glass tube, plastic, or other dielectric material.

  In the embodiment, the discharge tube 2 includes a tube main body 5 and high-voltage side electrodes (7, 10) to which an alternating high voltage is applied via the tube main body. A discharge is generated on the dielectric surface by an alternating high voltage applied between the electrodes, and ozone is generated by a reaction caused by dissociation and collision of supplied oxygen. Various types of creeping discharge type discharge tubes according to the embodiments may have different electrode attachment modes with respect to the discharge tube, but any type of discharge may be used as long as it functions in the specific application of the ozone generation and injection device of the present application. 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). And a large number of linear electrodes installed on the dielectric surface. In the present embodiment, for example, a stainless steel screw rod material is used for the high voltage electrode 7. The high voltage electrode 7 is threaded through a joint member 8 that seals one end side of the tube body 5, and has one end protruding outside. The other end side is inserted and arranged in the pipe body 5. In addition, a metal rod or a hollow pipe 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 into the tube body 5 and the inner wall of the tube body 5 by a support means (not shown). The high voltage electrode 7 is an internal electrode on the high voltage side arranged in the tube main body 5, and in the embodiment, the outer surface has a screw shape having, for example, sharp peaks and valleys. Thereby, 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 this 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 a gas containing oxygen is introduced into the gap 6 of the tube body, thereby Creeping discharge is generated on the dielectric surface as the tube body. The high-frequency high voltage can be supplied by boosting the commercial power supply. For example, by supplying the high-frequency high voltage via an inverter (not shown) using a small and light-weight semiconductor element, disinfection using the ozone generating / injecting apparatus 1 can be performed. The entire deodorizing and sterilizing device is made compact to contribute to the portability of the entire device.

  The joint member 8 fitted to the one end side 5a of the pipe body 5 is provided with a passage 12 communicating with the gap 6 as a gap. The passage 12 is connected to a gas pipe, oxygen cylinder (not shown) via a connection port 14. An oxygen generator 106 containing oxygen 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 distal end of the inserted high voltage electrode 7 and the distal end of the tube body 5.

  The connecting member 3 is a connecting means that is directly connected to the other end of the discharge tube 2 and allows ozone generated in the discharge tube to pass through and is connected to a nozzle portion 4 that discharges ozone to the outside. In particular, the connecting member 3 is a discharge tube. The ozone generated in the discharge tube 2 by being directly connected to the nozzle 2 is directly connected to the nozzle unit 4 without going through a pipe or a reservoir on the way. In the embodiment, the connection member 3 includes a connecting portion 22 that is connected to the other end portion 5 b of the tube body 5, and includes one or a plurality of passages 24 that allow ozone to pass through to the nozzle portion 4 side. Specifically, the connecting member 3 is formed of a cylindrical body of Teflon (registered trademark) material or ceramics, and has a connecting portion 22 configuration having a fitting hole 26 that detachably receives one end side of the tube body. Yes. And the inside of the connection member 3 and the pipe main body 5 is connected in an airtight state by an O-ring 30 held by a holding portion 28 disposed on the entrance side of the fitting hole 26. One or a plurality of passages 24 are formed along the flow direction of the ozone in communication with the bottom of the fitting hole 26 in the opposed thick portion of the connecting member 3 into which the tube body 5 has entered, and the discharge tube 2 The ozone generated in step 1 is supplied to the nozzle unit 4 via the space 20 and the passage 24.

  In the embodiment, the connection member 3 is connected to the other end side 5b of the discharge tube 2 so as to be freely fitted and detached, and the nozzle portion 4 can be easily set according to the number of thin tubes of the disinfectant and the difference in the arrangement. It can be exchanged.

In FIG. 1, the nozzle portion 4 includes one or a plurality of thin tubes 32 that are attached to the connection member 3 so as to communicate with the passage 24 of the connection member 3 and project in the flow direction F of ozone. In the embodiment, the narrow tube 32 is connected at one end side base portion to the passage passage outlet 24 a portion of the connection member 3. Thereby, the connecting member 3 and the thin tube 32 are integrated. For this reason, the nozzle part 4 is replaceable as an integral part of the connection member. The connecting member 3 and each thin tube can be attached and detached. 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 millimeters and a length of about 3 cm (centimeter). The connecting member 3 communicates with the passage 24 outlet 24a. The narrow tube 32 is formed to protrude from the passage passage outlet 24a of the connection member 3 so as to extend in the direction of ozone flow, and has directivity and injection force directed in the direction set by the thin tube configuration. Yes. From the distal end outlet 32a of the thin tube 32, there is not provided anything that causes airflow fluctuations such as a jet outlet by any other machine body, and is suddenly released to the atmosphere from the distal end outlet 32a. The ozone gas ejected from each narrow tube is ejected at a low pressure (for example, 1 L / min) almost equal to the atmosphere. For example, the wind pressure is hardly felt even when a hand is applied to the tip outlet 32a. Therefore, high-concentration ozone gas can be stably ejected from the narrow tube. The thin tubes 32 may be formed so as to project integrally with the connection member 3, or may be attached and connected one by one, or may be configured to be detachable one by one. Furthermore, in the present embodiment, the thin tube 32 can be bent by an operation of a human finger or the like, and has a degree of flexibility that can maintain the shape in a state after the bending. Thereby, the injection direction of each thin tube can be set individually, or the injection speed and the injection amount per time can be controlled. Further, the thin tubes 32 are arranged so as to converge within a certain area so that their outlets are arranged in a circle having a diameter around the diameter of the discharge tube 2, for example. The number of capillaries may be one, but in order to effectively exhibit the function of ozone, it is preferably 2 or more to several tens, particularly about 3 to 10. In the present embodiment, a total of five narrow tubes 32 are provided at the central portion and the surrounding 90 degrees apart (see FIG. 1b). As a result, the ozone (O ₃ ) generated and generated in the discharge tube 2 is almost directly jetted from the respective narrow tube outlets 32a toward the disinfectant without being reduced in concentration in the piping on the way, and the high concentration ozone gas is discharged. Can be reliably injected. In the embodiment, ozone gas is injected from each thin tube 32 by the feed pressure from the oxygen generator, and the injection pressure is injected as a low-pressure gas. Moreover, since it is a thin tube structure which protrudes from the wall surface of the connection member 3 and the tip is open to the atmosphere, no back flow to the ozone generator side is caused. Capillary The device of the present invention can be said to be an ozone generator / injection nozzle integrated device.

  In the present embodiment, there is further provided a cover 34 that is provided so as to wrap the narrow tube 32 of the nozzle portion 4 and has a large opening compared to the flow path diameter of the narrow tube. The cover 34 is a mist shield cover that shields the liquid mist from a mist nozzle portion, which will be described later, disposed concentrically on the outer periphery of the narrow tube 32 and the length of the stroke to the outlet of the narrow tube 32 so that ozone does not mix. In addition, the disinfection and deodorization effect by high-concentration ozone can be efficiently ejected by the operator in consideration of the angle and distance of the nozzle portion with respect to the object to be disinfected. Further, by covering the inner narrow tube 32 with the cover 34, the function of preventing the back flow of liquid to the discharge tube side directly connected to the narrow tube can be ensured. 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 part with the connection member 3 to one side and wrap the thin tube 32 inside, and is formed in a barrel shape or so as to gradually reduce the opening from the intermediate part to the tip part side. It has a spindle shape. As shown in FIG. 1, the shape of the cover may be a cover shape having a circular cross section in a circular arc shape from the base side which is a connection portion with the connection member 3 to the tip side having an opening as shown in FIG. It may be formed so that the opening gradually becomes smaller from the position of deviation (see FIG. 8). Moreover, you may form an intermediate part in a waveform. Further, in FIGS. 1 and 2, the tip of each thin tube 32 is set at a position retracted further back than the position of the opening 34 a of the cover 34. Thus, when ozone gas is injected from the narrow tube outlet 32a, a flow k is formed that is attracted to the opening 34a along the inner wall of the cover 34, and this flow acts to suppress the injection flow from the thin tube outlet 32a. The weakened flow is discharged from the opening 34a of the cover so as to diffuse to the surroundings, and the ozone gas is sufficiently jetted to the disinfectant so that the sterilization effect by the ozone gas is not limited in a short time by jet jetting. The function can be executed. Further, the cover 34 is formed in a barrel shape or a spindle shape so as to gradually reduce the opening on the injection side from the intermediate portion to the tip portion side, thereby making it difficult for outside air to enter the cover body from the outside, thereby reducing the ozone concentration. It makes it difficult to cause a decrease.

  3 and 4 show other examples 44B and 44C of the nozzle unit 4. FIG. The nozzle portion 44B of FIG. 3 has an overall shape of the cover 34 in the same manner as that of FIG. 1, and a barrel shape in which the entire portion is bulged and the central portion bulges and the both end sides gradually reduce the sectional opening. Alternatively, it is formed in a spindle shape. The nozzle portion 44B is provided with a reach distance suppression mechanism 36 that suppresses the reach distance of ozone by branching the middle or tip of one or more thin tubes in the cover 34 into a plurality of branches. In the nozzle portion 44B of FIG. 3, the pipe is further branched from one narrow pipe in three directions of two right-angled branch pipes 38a, 38b and one straight branch pipe 38c. The ozone emitted from the two right-angle branch pipes 38a and 38b hits the inner wall of the cover 34 in the orthogonal direction, hits the wall surface, becomes a reverse flow l, and is entirely turbulently q. Therefore, the turbulent flow q flows to the outlet portion of the straight branch pipe 38c, prevents the straight flow and becomes a resistance, and suppresses the reach distance after discharge. Therefore, the ozone gas exiting from the cover opening 34a is not a jet stream but a diffused diffused flow, whereby sufficient ozone gas can be locally and intensively injected onto the object to be disinfected. In the example of FIG. 3, the flow from the right-angle branch pipes 38a and 38b actively suppresses the jet flow of the straight branch pipe 38c. The generation of a gentle diffusion flow due to the low-pressure ozone gas flow and the shape of the cover 34 acts in a superimposed manner.

  Further, in the nozzle portion 44C of FIG. 4, the narrow tube 32 includes an expandable tube 40 whose length can be expanded and contracted. In the nozzle portion 44C of FIG. 4, for example, the telescopic thin tube 40 is formed by a main tube 41a and a slide tube 41b that is connected to the main tube 41a in a double cylinder shape and can be slid with a certain degree of frictional force. Yes. The sliding thin tube 41b slides in the longitudinal direction of the tube up to a certain position where it does not come out of the main body thin tube 41a, and is locked by a frictional force at an arbitrary position. Thereby, the overall length of the tubule can be varied. The telescopic tubule 40 may be configured for only a part of the plurality of tubules. By providing the telescopic tube 40, when spraying to a deep part where ozone injection is necessary for a specific object to be disinfected, the specific disinfecting part is surely sprayed with ozone and disinfected by performing in an extended state. be able to.

In FIG. 5, a nozzle portion 46A is provided in a barrel-shaped or spindle-shaped cover 34 similar to FIGS. 1 to 4, with one end connected to the connection member 3 with the ozone flow direction as the longitudinal direction. And converged in the cover 34. The nozzle portion 46A is provided with at least one protruding narrow tube 48a whose tip protrudes 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 so that their tips are located at positions retracted further back than the opening 34a. Since the nozzle portion 46A has ozone gas flows having different arrival distances of ozone gas ejected from the narrow tube, the nozzle portion 46A effectively disinfects the disinfectant that is long in the perspective direction by the ozone gas flows having a plurality of arrival distances in the ejection direction. Can have an effect.

  Further, the nozzle portion 46B of FIG. 6 has five capillaries 32 in one end connected to the connecting member 3 in the barrel-shaped or spindle-shaped cover 34 as in FIGS. The narrow tube 32 of the nozzle portion 46B is provided with at least one telescopic tube 40 whose length can be expanded and contracted. At least one of these telescopic tubes is provided with a tip protruding from the position of the opening 34 a of the cover 34. A telescopic tube 40 is formed by a main tube 41a and a main tube 41a connected to the main tube 41a in a double cylinder shape and slidable tube 41b that can slide with a certain degree of frictional force. The sliding thin tube 41b slides in the longitudinal direction of the tube up to a certain position where it does not come out of the main body thin tube 41a, and is locked by a frictional force at an arbitrary position. The telescopic tubule 40 may be configured for only a part of the plurality of tubules. The nozzle portion 46B also has an ozone gas flow in which the arrival distance of ozone gas ejected from the narrow tube is different, so it can be effectively disinfected even for a disinfectant that is long in the perspective direction due to the ozone gas flow at a plurality of arrival distances in the ejection direction. Although effective, the disinfection with respect to the disinfectant is more effective particularly in the case where the telescopic tube 40 whose tip protrudes from the position of the opening 34a of the cover 34 is sprayed in the depth direction where ozone spraying is necessary. Can have an effect.

  Further, the nozzle portion 46C of FIG. 7 has five capillaries 32 in one end connected to the connecting member 3 in the barrel or spindle-shaped cover 34 as in FIGS. The nozzle portion 46C is provided with at least one protruding narrow tube 48a whose tip protrudes from the position of the opening 34a of the cover 34. The overall shape of the cover 34 of the nozzle portion 44C is a barrel shape or a spindle shape in which the overall shape is a circular arc-shaped cross-sectional cover shape as in FIG. 1, and the central portion bulges and both end sides gradually reduce the cross-sectional opening. Is formed. In the nozzle portion 46C of FIG. 7, an arrival distance suppression mechanism 36 that suppresses the arrival distance of ozone by branching the middle or tip of one or more thin tubes in the cover 34 into a plurality of portions is provided. In the nozzle portion 46C of FIG. 7, the pipe is further branched in two directions of two right-angled branch pipes 49a and 49b in the vertical and vertical directions from the tip of the narrow tube 49 having a tip position behind the opening 34a of the cover 34. . The ozone emitted from the two right-angle branch tubes 49a and 49b strikes the inner wall of the cover 34 in the orthogonal direction, hits the wall surface, becomes a reverse flow, and is entirely turbulent. Therefore, this turbulent flow flows to the opening 34a side of the cover 34 to perform the function of suppressing the reach of the straight flow from other thin tubes (not shown) and becomes a gentle flow from the opening 34a to the outside of the cover 34. leak. In the nozzle portion 46C, the ozone gas exiting from the cover opening 34a can simultaneously inject a jet stream and a diffusing diffused flow at the same time, and thereby sufficient ozone gas is locally distributed in the perspective direction and the three-dimensional spreading direction. In addition, it can be intensively sprayed onto the object to be disinfected.

  As shown in FIGS. 1 to 7, the cover 34 has a bag shape extending in one direction from the connection portion with the connection member 3 and wrapping the narrow tube 32 inside, and has an arc-shaped cross section, barrel shape or spindle shape. For example, as shown in FIG. 8 (the thin tube is not shown), the tube is straightened to the middle so as to extend from the connecting portion with the connecting member 3 to the one side and wrap the thin tube 32 inside, and gradually from the intermediate position. The tip opening may be made smaller.

  Returning to FIG. 1, a cooling jacket portion 50 for holding a cooling liquid is disposed on the outer periphery of the discharge tube 2. Further, the cooling liquid in the cooling jacket portion 50 is misted and sprayed to the outer peripheral portion of ozone gas. A nozzle portion 52 is provided. The cooling jacket part 50 cools the discharge tube 2 heated by the heat generated by the discharge. The discharge tube 2 is accommodated in a cylindrical casing 54 together with a cooling jacket portion 50 disposed on the outer periphery, and an operator can hold the casing 54 portion and perform disinfection work using ozone gas. Specifically, the cylindrical housing 54 is formed with a length slightly longer than the distal end of the tube main body 5 of the discharge tube 2, and a recess 56 is provided at the distal end portion on the other end side of the tube main body. The tube main body 5 is positioned and installed so that the other end 5b protrudes into the concave space. Specifically, the connection member 3 carrying the thin tube 32 is fitted into the recess 56 and is hermetically held by the O-ring 30 so that the inside of the tube body 5 and the passage 24 of the connection member 3 communicate with each other.

  In the embodiment, the cooling jacket portion 50 is composed of a cooling pipe 58 that is wound around the outer circumference of the discharge tube 2 in the longitudinal direction and wound in a spiral manner in contact with the ground electrode 10 of the discharge tube. A liquid such as water is supplied via a liquid supply pipe connected to the cooling pipe 58 and a pump, and the outer periphery of the discharge pipe 2 is cooled from the surface. The cooling jacket portion 50 is not limited to the spiral winding mode of the cooling pipe as in the embodiment, and is provided so as to be in close contact with the ground electrode 10 so as to cover the entire outer periphery or a part of the tube body 5 from above. A so-called jacket-type cooling structure can also be used. Moreover, the cooling jacket part 50 is good also as a structure which touches the outer periphery of a discharge tube indirectly, and hold | maintains a pressure-feeding coolant.

  Further, in the embodiment of FIG. 1, a mist nozzle portion 52 in which a mist nozzle 68 is held by a nozzle holding portion 66 is provided on the tube body other end portion 5 b side of the cylindrical casing 54. The mist nozzle portion 52 is directly connected to the cooling jacket portion 50 and is disposed in the vicinity of the outer periphery of the thin tube 32 to spray the liquid from the cooling jacket portion 50 in the mist state in the same flow direction as ozone gas. In the embodiment, for example, water is atomized and the water mist S is sprayed on the outer peripheral portion of the thin tube 32 as described above. Specifically, a nozzle holding portion 66 that is enlarged from the covering portion of the cooling jacket portion is provided on the tube main body other end portion 5b side of the cylindrical casing 54, and the end surface of the nozzle holding portion 66 in the ozone gas flow direction is provided. The mist nozzles 68 are concentrically arranged outside the outer periphery of the place where the thin tubes 32 are disposed, with the outlets of the numerous fine holes 68a exposed. In the embodiment, as shown in FIG. 1 (b), four nozzle elements 69 are disposed at positions approximately 90 degrees apart from each other on the outer side of the cover 34 that surrounds the narrow tube 32, each of which is a water mist. To spray. Further, in this embodiment, the mist nozzle 68 is disposed at the outer peripheral position of the connection member 3 that supports the cover 34 and is in a position retracted from the cover 34 in the ozone flow direction. 34 may be arranged at the outer surface position. The mist nozzle 68 is preferably detachable and replaceable by a fitting type, a screw-in type, or other methods. In this case, the mist nozzle 68 includes a plurality of nozzle bodies that can generate liquid mist ejected from the nozzle, such as a donut-shaped mist, a circular mist that intensively injects into a small range, and a mist dispersed in small sections. By preparing and selectively using these, disinfection work corresponding to a specific object to be disinfected can be performed. In the present embodiment, a further advantage is that the cooling liquid for cooling the discharge tube 2 is used as the liquid mist. Specifically, in the present embodiment, the cooling liquid is supplied to the nozzle holder 66. A plurality of branch pipes 70 whose one ends are connected in communication with the liquid pipe 58 are arranged, and the other end sides of the branch pipes 70 are communicated with the respective nozzle elements 69 of the mist nozzle portion 52, and the fine holes 68a of the nozzle elements. Liquid mist is jetted from. As a result, the cooling water of the discharge tube can be used as ozone reaction water as it is. For example, the whole apparatus can be reduced in size and weight by using a single supply source of cooling water and mist water and a pump for driving. In addition, the cost can be reduced by simplifying the supply piping. Moreover, in this embodiment, since the liquid (water) supplied to the mist nozzle 68 is supplied with low-pressure water, it is possible to prevent a liquid backflow from the narrow tube 32 to the ozone generating means side.

  The liquid supplied to the mist nozzle 68 that generates 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, and is pumped by, for example, a pump (not shown). The liquid may be supplied to the mist nozzle 68 to generate the liquid mist. Moreover, it is good also as what was equipped with the cooling mechanism by air cooling, such as not only the cooling of the discharge tube with a liquid but a cooling fan. Furthermore, if a discharge tube configuration that does not cause decomposition of ozone generated by condition setting can be achieved, the cooling mechanism itself need not be provided.

  Next, the operation of the ozone generation / injection apparatus 1 of the present embodiment will be described. First, the operation of the entire apparatus will be described with reference to FIGS. 1 and 2. Oxygen generated by an oxygen generator (not shown) is supplied to the gap 6 of the discharge tube 2 through the gas pipe, the connection port 14 of the joint member, and the passage 12. . Further, water is supplied to a 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 and the ground electrode 10 of the discharge tube, ozone is caused by dissociation of oxygen molecules and collision of oxygen atoms, oxygen molecules, and three bodies by a large number of pulsed microdischarges. Is generated. Ozone flows in the direction of arrow F from right to left in FIG. 1 due to the pressure of the oxygen generator, and passes through the plurality of passages 24 of the connecting member 3 via the space 20 at the other end of the tube body. High concentration ozone is injected from 32. At this time, since the plurality of thin tubes 32 are converged and provided with the same direction as the flow direction of ozone as the longitudinal direction, ozone is ejected from each small dot-shaped tube outlet at a slow flow rate. During this time, the discharge tube heated by the discharge is cooled by the water supplied into the cooling pipe 58 that is spirally wound in contact with the ground electrode 10 on the outer surface of the tube body. Further, 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 the region of the outlet of the narrow tube from the outlet of each fine hole 68 a to the outer periphery of the narrow tube, that is, the cover 34. The water mist is sprayed concentrically. The ozone sprayed from the narrow tube is sprayed or sprayed toward the body to be disinfected together with the water mist sprayed outside the region of the narrow tube outlet. At this time, a liquid mist having a particle size of about 80 μm to 100 μm spreads immediately before the apparatus 1, and further, ozone is gently dispersed in the mist and sprayed onto the object to be disinfected.

  By variously changing the shape of the cover 34 and the attachment mode and structure of the thin tube 32, it is possible to perform an injection 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 more thin tubes is branched into a plurality of branches and directly applied to the inner wall of the cover 34, thereby generating a reverse flow and turbulently moving the whole to reach the reach distance. A suppression mechanism is formed. This turbulent flow causes a resistance component of straight flow, and it is injected outside the cover as a diffusion flow that spreads slowly while maintaining high-concentration ozone while preventing inflow of external air into the back and mixing with ozone, Sufficient ozone gas can be injected locally and intensively onto the object to be disinfected.

  In addition, as shown in FIGS. 4 and 6, it is possible to change the entire length of the narrow tube as a configuration in which the individual thin tube itself can expand and contract, so that sufficient ozone injection can be performed when spraying on uneven portions. Is possible.

  Further, as shown in FIG. 5 to FIG. 7, by providing a protruding narrow tube 48 a that protrudes from the position of the opening 34 a of the cover 34, it is possible to inject ozone gas having different arrival distances of ozone gas injected from the thin tube. The disinfection work can be effectively performed even on a disinfectant that is long in the perspective direction.
