Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for managing an animal-rearing house by using a specific ozone water produced by a prescribed treatment and having specific physical properties; and also to provide a device for producing the ozone water. <P>SOLUTION: This method for managing the animal-rearing house comprises repeating the spraying of the specific ozone water having ≥3 ppm initial concentration and ≥5 min half life of the ozone gas concentration on leaving it in an atmosphere, from spraying devices arranged at the indoor ceiling side of the animal-rearing house to the inside of the rearing house under rearing the animals by a prescribed timing. Thereby, it is possible to cool down and also humidify the inside of the rearing house with the ozone water sprayed as a mist state. On falling down the mist state small granular ozone water drops from the ceiling side slowly, they have an effect of decomposing and deodorizing the bad smelling components in air. By sucking the mist state ozone water, the noses and respiratory organs of the animals are sterilized and disinfected. Since the releasing rate of the ozone is sufficiently moderate, there is no irritation to the respiratory organs. <P>COPYRIGHT: (C)2007,JPO&INPIT

Here, the conventional technique has the following problems to be solved.
As described in the above-mentioned literature, ozone water has an effect of sterilization and sterilization, but those manufactured by a normal method suddenly release ozone when left in the atmosphere. If high-concentration ozone water is used, ozone is rapidly released, so that the ozone gas concentration in the atmosphere becomes very high. This ozone can harm the respiratory organs of animals and harm health. It is said that the presence of ozone at a concentration of 2 ppm or more in the air is harmful. High-concentration ozone water exceeding 10 ppm described in patent documents and the like is not practical. On the other hand, low-concentration ozone water becomes water in several tens of seconds when sprayed or the like, and sufficient sterilization and deodorizing effects cannot be expected for the object.
The present invention has been made paying attention to the above points, and provides an animal breeding house management method and an ozone water production apparatus using specific ozone water produced by a predetermined treatment and having special physical properties. With the goal.

In each embodiment of the present invention, the above-described problems are solved by the following configurations.
<Configuration 1>
The spraying device placed on the indoor ceiling side of the animal breeding house has an initial concentration of 3 ppm or more inside the breeding house where the animal is raised, and the ozone gas concentration has a half-life of 5 when left in the atmosphere. An animal breeding house management method characterized by repeating the process of spraying specific ozone water for more than a minute at a predetermined timing.

  The inside of the breeding house can be cooled with ozone water sprayed in a mist form. It can also be humidified. Further, when the mist-like small ozone water drops slowly descend indoors from the ceiling side, there is an effect of decomposing and deodorizing the malodorous components in the air. Inhalation of mist-like ozone water sterilizes animal noses and respiratory organs. Existing ozone water has an odor of ozone, but specific ozone water has a sufficiently slow release rate of ozone, so there is no irritation to the respiratory tract.

<Configuration 2>
In the animal breeding house management method according to Configuration 1, the spray device sprays ozone water droplets having a particle size of 1 mm or less, and the specific ozone water is in a room having a temperature of 35 degrees Celsius or less and has an initial concentration of 5 ppm or less. An animal breeding house management method, wherein the ozone gas concentration is a specific ozone water having a half-life of 5 minutes or more when left in the atmosphere.

  When existing ozone water is sprayed, water and ozone are separated immediately. The specific ozone water used here is sprayed with a particle size of 1 mm or less in a room having a temperature of 35 degrees Celsius or less. At this time, ozone water having an initial concentration of 5 ppm or less and a half-life of ozone gas concentration of 5 minutes or more when left in the atmosphere is used. Even when sprayed, the release rate of ozone gas is slow and does not emit strong ozone odor. Also, after descent, the effectiveness of sterilization, disinfection, deodorization, etc. with ozone water is not lost.

<Configuration 3>
The shower nozzle arranged on the indoor ceiling side of the animal breeding house has an initial concentration of 3 ppm or more in the water descended on the floor so that the animal falls into the breeding house where the animal is being raised. A method for managing an animal breeding house, characterized in that the treatment of spraying specific ozone water having a half-life of ozone gas concentration of 5 minutes or more when left in the chamber is repeated at a predetermined timing.

  When ozone water is sprayed on an animal, the animal's body can be cooled, washed, and skin sterilized. At the same time, the animal can be made to drink ozone water automatically, the animal's mouth can be sterilized, and digestive diseases can be prevented. In addition, spraying ozone water uniformly throughout the animal breeding house has the effect of disinfecting, sterilizing and deodorizing the entire breeding house floor. It is not toxic even if it is applied to food, and it can prevent spoilage. Ozone water whose ozone gas concentration is rapidly reduced lacks the ability to disinfect the floor after the animal has been washed.

<Configuration 4>
In the animal breeding house management method described in any one of Structures 1 to 3, the specific ozone water has an initial concentration of 3.5 ppm or more and an ozone gas concentration within 1 minute when left in a room with a temperature of 35 degrees Celsius or less. An animal breeding house management method characterized in that the state is reduced from a state where the concentration is reduced by 1 ppm or more.

When left in a room with a temperature of 35 degrees Celsius or less, the initial concentration is 3.5 ppm or more, and the ozone gas concentration is less than 1 ppm within 1 minute. The ozone odor can be kept low.
<Configuration 5>
A circulation pipe for extracting ozone water stored in the storage tank, a mixing device for mixing ozone gas with the ozone water extracted by the circulation pipe, a temporary storage tank for receiving ozone water from the mixing device and temporarily storing ozone water, A return pipe that returns ozone water from the temporary storage tank to the storage tank, and a barrier member that generates a turbulent flow in the ozone water that flows through the flow path is provided inside the storage tank. An ozone, characterized in that a stirrer disposed and a rectifying unit that pushes ozone water in a certain direction in a flow path following the stirrer are disposed, and a gas reservoir is provided at least above the water surface above the stirrer. Water production equipment.

After mixing ozone gas with water, turbulence is generated in the ozone water and stirred to increase the productivity of ozone water with a long half-life. Furthermore, ozone gas can be uniformly dispersed in ozone water by providing a rectifying unit. At the same time, ozone gas that is not sufficiently dissolved in ozone water by stirring can be discharged through the gas reservoir. Therefore, when ozone water is taken out into the atmosphere, the amount of ozone that is rapidly released can be reduced, and high-concentration ozone water can be used safely.
<Configuration 6>
In the ozone water producing apparatus according to Configuration 6, the storage tank is a cylindrical container, and the return pipe that returns the ozone water from the temporary storage tank to the storage tank has a circular shape that allows the ozone water to pass through the inside of the storage tank. An ozone water production apparatus characterized in that its tip is directed in a tangential direction of a cylinder of a storage tank so as to draw and flow.

  By holding the ozone water so as to flow in a certain direction inside the storage tank, it is possible to prevent the dissolved ozone gas from being released.

  Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is a cross-sectional view of an animal breeding house in which the method of Example 1 is implemented and a schematic diagram of an ozone water supply facility.
As shown in the figure, an animal 20 such as a pig is raised in the breeding house 10. A storage tank 11 for storing ozone water is disposed on the land or roof adjacent to the breeding house 10. The storage tank 11 stores specific ozone water whose concentration is adjusted and the characteristics of ozone are further adjusted. The circulation pipe 18 is a pipe for supplying ozone water from the storage tank 11 to the mixing device 15. The circulation pipe 18 is provided with a temperature sensor 27 and a pump 21. The ozone gas generator 12, the valve device 13, and the injection pipe 16 are a system for supplying ozone gas to the mixing device 15. Note that ozone gas discharged from the temporary storage tank 40 is supplied to the valve device 13 through a gas vent pipe 42. The ozone water mixed with ozone gas by the mixing device 15 returns to the storage tank 11 through the connection pipe 24, the temporary storage tank 40, and the return pipe 19. The water supply pipe 17 is a pipe that supplies tap water or the like into the storage tank 11. The recovery pipe 14 is a pipe that discharges ozone gas released from ozone water in the storage tank 11 through the filter 56.

  The ozone gas generator 12 is an apparatus that separates oxygen from the air and ozonizes the oxygen by corona discharge or the like. As this apparatus, for example, one described in Patent Document 3 or the like can be used. The valve device 13 is for supplying the ozone generated by the ozone gas generator 12 and the ozone gas recovered from the upper part of the temporary storage tank 40 through the gas vent pipe 42 to the mixing device 15. The mixing device 15 is a device that mixes ozone gas supplied from the valve device 13 into ozone water taken out from the storage tank 11 through the circulation pipe 18 and sends it to the temporary storage tank 40 through the connection pipe 24.

  For the mixing device 15, for example, a valve device as described in Patent Document 4 may be used. The ozone water stored in the storage tank 11 is taken out using the circulation pipe 18, and the ozone gas concentration in the ozone water is increased by repeatedly mixing new ozone gas. At this time, the ozone gas that has become fine bubbles sufficiently dissolved in the ozone water continues to be held in the ozone water as it is. On the other hand, large-bubble ozone gas is rapidly diffused into the air. Although such ozone gas temporarily increases the concentration of ozone water, it rapidly diverges into the air, so the concentration of ozone gas in the air is increased and causes a strong ozone odor. Then, it discharges through the discharge pipe 14 to the upper part of the storage tank 11. The filter 56 is for detoxifying the ozone gas. .

  Thus, the concentration of ozone gas that dissolves in the ozone water inside the storage tank 11 and is not easily discharged into the air increases. The density is adjusted as described later. Thus, the specific ozone water according to the present invention is produced. A water supply pipe 29 is attached to the storage tank 11. This water supply pipe 29 is provided with a temperature sensor 27 and a water supply pipe 29. The specific ozone water in the storage tank 11 is sent to the breeding house 10 through the water supply pipe 29 by the pump 21. A frame 25 is provided on the ceiling portion of the breeding house 10. Here, an arbitrary number of spraying devices 26 are fixed. Ozone water is supplied to this spraying device 26 using a pump 23. In addition, the temperature sensor 27 is arrange | positioned at each place of piping, the temperature of ozone water is controlled, and the fall of ozone gas concentration is prevented.

  The ozone water is sprayed into the atmosphere by the spray device 26. The mist of the ozone water 30 slowly descends inside the animal breeding house 10. As is well known, spraying water into the air can lower the temperature. For example, when the temperature inside the breeding house rises during the summer day, the temperature inside the breeding house can be lowered by several degrees or more by spraying ozone water. Therefore, the pump 21 is intermittently driven using the temperature sensor 33 and the electromagnetic relay 22. For example, when the temperature exceeds 30 degrees, the electromagnetic relay 22 is operated to start the pump 21. When the temperature drops to 27 degrees, the pump 21 is stopped.

  On the other hand, this fog slowly descends from the top of the breeding house. Inside the breeding house 10, there is a strong odor and there are pests and the like. This is decomposed by the fog of ozone water or pests are exterminated. Furthermore, this mist adheres to the body of the animal 20 and lowers the body temperature. It also contributes to the purification of the skin surface.

  When the specific ozone water is sprayed by the spray device arranged on the indoor ceiling side of the breeding house, the fog of the specific ozone water can be spread throughout the breeding house. Spray for the purpose of purifying the air inside the breeding house. Specific ozone water having an initial concentration of 3 ppm or more and an ozone gas concentration half-life of 5 minutes or more when left in the atmosphere has a slow release rate of ozone gas and does not emit a strong ozone odor even when sprayed. Also, after descent, the effectiveness of sterilization, disinfection, deodorization, etc. with ozone water is not lost. Moreover, the mist adheres to the animal's skin or is sucked into the nose or the like, and exhibits sterilization and disinfection effects. For example, it can prevent skin diseases in piglets and accelerate healing. Actually, according to the above apparatus, it was most economical to produce a product having an initial concentration of 3 ppm to 4 ppm, and a product having a sufficiently long half-life could be produced.

  Furthermore, when sprayed in a room with a particle size of 1 mm or less in a room with a temperature of 35 degrees Celsius or less, ozone water having an initial concentration of 5 ppm or less and a half-life of ozone gas concentration when left in the atmosphere of 5 minutes or more Is used. This range satisfies the conditions that the concentration can be efficiently produced, that it is an appropriate concentration that does not adversely affect animals, and that the effect of ozone is maintained within a practical range. When sprayed in a room with a particle size of 1 mm or less in a room with a temperature of 35 degrees Celsius or less, the ozone water is in a severe condition where ozone gas is easily released. A concentration that is practical under these conditions and has a long half-life is preferable. In the case of ozone water having a concentration of about 5 ppm to 7 ppm at the time of production, ozone is suddenly released to a concentration near 5 ppm. This shows a characteristic close to that of conventional ozone water. Therefore, it is preferable to discharge the ozone gas until the ozone gas concentration becomes 5 ppm or less and stabilize the ozone gas before supplying it to the sprayer. Moreover, even if ozone gas with a high concentration is released in the upper part of the breeding house, it reacts immediately with the surrounding odorous gas. Therefore, it does not affect people or animals below. If an attempt is made to produce a higher concentration of ozone water with a half-life of 5 minutes or more, the treatment time will be significantly increased and the cost will increase. Moreover, the concentration of ozone gas that is temporarily released into the air from the initial state becomes too high, which is not suitable for animal breeding houses.

FIG. 2 is a cross-sectional view of an animal breeding house in which the method of Example 2 was performed.
In the breeding house 10, a number of shower nozzles 28 are fixed to a frame 25 disposed on the ceiling side. Ozone water 31 is sprinkled from the shower nozzle 28. The ozone water 31 that has flowed down falls on the animal 20. Other ozone water is sprayed on the floor 32. Sterilize floor manure to create a comfortable environment. Prevents the hatching of pupa eggs laid in manure and prevents the generation of pupae. Decompose organic matter that causes floor slimming to eliminate slipping. The shower is used to wash the animal's body directly and strongly. In addition, the animal 20 drinks the ozone water 31 that has flowed down. This allows sterilization of the animal's mouth. The animal's mouth is sterilized and the intestinal bacteria are stabilized, so that diarrhea and the like are stopped, and the animal's appetite is increased to improve health.

  With the shower nozzle, the animal is lowered to the floor so that it falls on the inside of the breeding house where the animal is being raised. Since the main purpose is washing animals, it is preferable to target highly established places where animals exist. It is preferable to maintain a certain level of concentration in the ozone water descending to the floor, which is effective for floor disinfection and deodorization. In addition, the specific ozone water does not hurt the respiratory organs of animals because the rate of releasing ozone into the air is low. There is no harm to workers who take care of animals. It also has the effect of cooling the animal's body. It is good to control so that the process which sprinkles specific ozone water is performed at the timing different from operation | movement of a spraying apparatus.

FIG. 3 and FIG. 4 are explanatory diagrams for the characteristic test of ozone water.
The properties of specific ozone water that brings about the above effects were demonstrated. As shown in the figure, the ozone water 30 sprayed from the spray device 26 descends in the air and is received by the dish 34. When conventional ozone water having a low concentration or high concentration is sprayed into the air using the spray device 26 as shown in this figure, the ozone is immediately separated from the water. Therefore, the ozone water that has fallen is collected in the dish 34 and the ozone gas concentration is measured to be almost zero ppm. The smaller the particle size of the water when sprayed, the easier it is to release ozone gas. However, since the above-mentioned specific ozone water is sufficiently dissolved in water to form fine bubbles, ozone gas concentration of a certain amount or more is exhibited even after being sprayed and lowered. This contributes to animal disinfection. When ozone water having an initial concentration of 5 ppm was sprayed in the form of a mist as shown in FIG. 3, the ozone gas concentration of the ozone water in the dish 34 was 1.3 ppm. Further, when ozone water having the same concentration was sprayed in the shower as shown in FIG. 4, the ozone gas concentration of the ozone water in the dish 34 was 3.4 ppm. These ozone waters contribute to the cleaning of the animal body, the cleaning of the breeding house floor, and the disinfection and deodorization. Moreover, the ozone gas density | concentration in air | atmosphere of 1.7m above-ground when spraying fog was 0.42 ppm. Further, the ozone gas concentration in the atmosphere 1 m above the ground was 0.43 ppm. All were well below the standard value of 2 ppm, had almost no ozone odor, and were harmless to animals.

FIG. 5 is a graph showing the ozone gas concentration measurement test result of the specific ozone water.
In the graph, the horizontal axis represents time (unit: second), and the vertical axis represents ozone gas concentration (unit: ppm). This measured value can be obtained by standing at room temperature and atmospheric pressure in a state where ozone water is contained in a dish having a constant diameter and sequentially measuring the concentration after a certain period of time. The temperature at the time of measurement was 32 degrees Celsius, humidity 52%, water temperature 29 degrees Celsius, the concentration of 500 ml of ozone water was monitored with an ozone water concentration meter, and the phenomenon of concentration was measured almost continuously. The initial concentration of ozone water was 5 ppm.

  As can be seen from this graph, it took 18 minutes and 5 seconds for the specific ozone water of 5 ppm to reach an ozone gas concentration of 0 ppm. During the first minute, the ozone gas concentration dropped sharply to 3.8 ppm. Thereafter, the concentration was lowered while slowly releasing ozone gas. Its half-life with respect to its initial concentration is 5 minutes, and after reaching 3.8 ppm, the subsequent half-life is about 9 minutes. Even after spraying, it is sufficient to keep the ozone gas concentration for a while and then disinfect and sterilize. The characteristic was shown. The slow decrease in ozone concentration means that the concentration of ozone gas released into the air is low and functions as ozone water for disinfection and deodorization for a long time. That is, if the initial concentration is 3.5 ppm or higher and the ozone gas concentration is removed from the state where the ozone gas concentration decreases by 1 ppm or more within 1 minute, it is a breeding house with ozone water that releases less ozone gas and is safe and effective from the beginning. Management is possible.

FIG. 6 is a graph showing an ozone gas concentration measurement test result of ozone water of a comparative example.
This is ozone water having an initial concentration of 3.2 ppm manufactured by a conventional method, and other measurement conditions are the same as those in the embodiment of FIG. As can be seen from the graph, it took 2 minutes until the ozone water had an ozone gas concentration of 0 ppm. During the first minute, the ozone gas concentration dropped sharply to 1 ppm. After that, when the ozone gas concentration suddenly drops to about 0 minute, the ozone gas concentration in the animal breeding house temporarily becomes high, and a strong ozone smell is felt. From this comparison result, it was also clarified that the above specific ozone water is optimal for animal breeding houses.

  The livestock industry is changing jobs and going out of business due to a lack of manpower. The problem is that the workplace environment is poor and the retention rate of workers is poor. Specific ozone water solves these problems and improves not only the breeding house but also the surrounding environment. In particular, the odor of ammonia gas is quickly decomposed and removed by spraying specific ozone water. Moreover, the health of the animal is maintained by the bactericidal effect of the floating bacteria, and the working environment of the worker is improved. Moreover, said specific ozone water can be used for hand-washing. It can also be used for prior application and gargle before and after work. For example, it is useful for cleaning and sterilizing instruments and hands for caring for animals such as nursing care for children, and is very effective for removing hand and body odors after work. That is, the specific ozone water that satisfies the above conditions can be widely used for spraying, showering, hand washing, and the like, and it can be said that it is extremely useful to use it in animal breeding houses.

FIG. 7 is a longitudinal sectional view of an embodiment of the mixing apparatus.
Hereinafter, a specific example of an ozone water production apparatus suitable for the above embodiment will be described.
The mixing device 15 includes a venturi pipe 36 for mixing the ozone water sucked from the circulation pipe 18 and the ozone gas sucked from the injection pipe 16. An enlarged diameter portion 37 is provided downstream of the venturi tube 36. Here, the block 38 is arranged so that the ozone water collides by obstructing the flow of the ozone water. When the ozone water collides with the block 38, a turbulent flow is generated in the ozone water. The block 38 functions as a partition member. At that time, the bubbles of ozone gas in the ozone water become finer, increasing the solubility in water. The mixing device 15 is connected to the temporary storage tank 40 via a connecting pipe 24. The temporary storage tank 40 produces stable ozone water with a long half-life.

FIG. 8 is a longitudinal sectional view of an embodiment of the temporary storage tank 40.
The temporary storage tank 40 has a structure in which a triple inner pipe 44, an intermediate pipe 45, and an outer pipe 46 are arranged coaxially. The connecting pipe 24 was connected to the lowermost end of the inner pipe 44. The connecting pipe 24 is connected so as to penetrate the outer wall of the temporary storage tank 40 and reach the inner pipe 44. The inner pipe 44 constitutes the stirring unit 60. A barrier member 47 is disposed inside the inner pipe 44. The barrier member 47 constitutes a barrier that generates a turbulent flow in the ozone water flowing in the flow path from the bottom to the top. The barrier member 47 is preferably a rod-shaped structure having irregularities. A connection hole 48 penetrating the inner pipe 44 is formed in the upper part of the inner pipe 44. The ozone water flows out between the inner pipe 44 and the middle pipe 45 from the connection hole 48.

  Between the inner pipe 44 and the middle pipe 45, a flow path of ozone water from the upper side to the lower side is formed. The lower end of the middle pipe 45 is above the bottom of the temporary storage tank 40, and the ozone water flow path is formed between the middle pipe 45 and the outer pipe 46. Here, the ozone water goes from the bottom to the top. A return pipe 19 is connected to the upper part of the outer wall of the temporary storage tank 40. The ozone water goes from here to the storage tank 11. The flow path between the inner pipe 44 and the middle pipe 45 and between the middle pipe 45 and the outer pipe 46 forms a rectifying unit 61 that pushes ozone water in a certain direction.

  The upper part of each flow path is sealed with a lower flange 54. The lower flange 54 is provided with a gas vent hole 52 for extracting ozone gas from the water surface of each flow path. An upper flange 55 is overlaid on the upper surface of the lower flange 54. A gas reservoir 53 is formed in a space sandwiched between the lower flange 54 and the upper flange 55. A gas separation device 41 is connected to the gas reservoir 53. When the ozone gas accumulates in the gas reservoir 53, the gas separation device 41 automatically opens the valve and releases the ozone gas toward the gas vent pipe 42. This ozone gas is supplied to the injection pipe 16 through the valve device 13.

  In the apparatus having the above configuration, the ozone water flowing in from the connecting pipe 24 collides with the barrier member 47 in the stirring unit 60 and is stirred. Thereby, the bubble of ozone gas is refined | miniaturized and melt | dissolves sufficiently in water. In addition, ozone gas that has not sufficiently dissolved during the stirring process is accumulated in the gas reservoir 53 through the gas vent hole 52 located above the stirring unit 60. Thereafter, the ozone water descends after passing through the connecting hole 48, and reverses and rises at the bottom. The rectifying unit 61 uniformly melts ozone gas bubbles into the ozone water. When fine bubbles of ozone gas collide with each other and become larger bubbles, they are released into the air. Accordingly, the bubbles are dispersed in a constant flow so that the intervals between the fine bubbles of the ozone gas are uniform. The rectifying unit 61 has the function.

FIG. 9 is a cross-sectional view of an embodiment of the storage tank 11.
The ozone water taken out through the return pipe 19 is accumulated in the storage tank 11. At this time, if ozone water is dropped like tap water, ozone gas is easily released. Therefore, the tip of the return pipe 19 is extended to the bottom of the storage tank 11. Further, the storage tank 11 is a cylindrical container, and the tip of the return pipe 19 is directed in the tangential direction of the cylinder. As a result, the ozone water continues to flow inside the storage tank 11 in a circle. When ozone water is allowed to flow in a certain direction inside the storage tank 11, the action of dispersing bubbles of ozone gas also works inside the storage tank 11. Accordingly, ozone water having a high concentration and a long half-life can be accumulated. The ozone gas released by gasification inside the storage tank 11 can be minimized. The apparatus as described above can be widely used not only in animal breeding houses but also in systems that supply ozone water with a long half-life.
