  Next, the outline of the disinfection method by the barn disinfection system of this embodiment is demonstrated with reference to FIG.1 and FIG.2.

  In advance, the barn disinfection system of the present embodiment passes tap water and well water or river water in accordance with the water quality standard of the tap water through the pipe F through the pipe and mixes the raw water with salt. The water generator 1 decomposes and generates electrolyzed water of acidic water and alkaline water by electrolysis and stores them in the acidic water storage tank T0 and the alkaline water storage tank T1, respectively. The raw water is stored directly in the raw water storage tank T2. It is assumed that the pumps of each line are in a driving state.

First, the control unit C supplies raw water from the water supply line 5 to the electrolyzed water generating device 1, and electrolyzes salt water based on this raw water by the electrolyzed water generating device 1 to separate and produce acidic water and alkaline water. Furthermore, these are separately stored in the acidic water storage tank T0 and the alkaline water storage tank T1. In addition, the electrolyzed water production | generation by this electrolyzed water production | generation apparatus 1 is performed sequentially according to the residual amount in the acidic water storage tank T0 and the alkaline water storage tank T1, and the usage-amount of each electrolysis water, considering the production | generation capability of an apparatus. The acidic water storage tank T0 and the alkaline water storage tank T1 are controlled so as not to be emptied.
On the other hand, raw water is also supplied from the water supply line 5 to the raw water storage tank T2, and the raw water is sequentially stored.

  Next, in order to allow alkaline water to flow to the block that is first sterilized among the blocks, for example, the spray nozzle 10 disposed in the block A, the control unit C is configured to use the alkali in the piping path to the block A. The electric valve M of the water line 3b is opened. Thereby, alkaline water is washed and sprayed from the spray nozzle 10 only to the block A. This first alkaline water spraying is performed for 10 seconds, for example, and after the spraying time is over, the control valve C closes the electric valve M.

  Next, the control unit C opens the acidic water line 3 a in the piping path to the block A and introduces acidic water into the spray piping network 3. Thereby, acidic water is sterilized and sprayed from the spray nozzle 10 only to the block A. This acidic water spraying is performed for 20 seconds, for example, and after the spraying time is over, the electric valve M is closed by the control unit C.

  Next, the control unit C opens the electric valve M of the alkaline water line 3 b in the piping path to the block A again, and introduces alkaline water into the spraying piping network 3. Thereby, the alkaline water is neutralized and sprayed from the spray nozzle 10 only to the block A. The second alkaline water spraying is performed for 10 seconds, for example, and after the spraying time is over, the electric valve M is closed by the control unit C.

  Furthermore, the control unit C opens the electric valve M of the raw water line 3 c in the piping path to the block A, and introduces raw water into the spraying piping network 3. Further, the controller C introduces potassium carbonate at a predetermined concentration into the raw water line 3c by the potassium carbonate addition device TC. Thereby, the raw water in which potassium carbonate is added only to the block A is sprayed from the spray nozzle 10. This raw water spraying is performed for 20 seconds, for example, and after the spraying time is over, the control valve C closes the electric valve M. Thereby, the first sterilization processing of the block A is completed.

  The series of steps of the sterilization process is repeated in the same manner in the other blocks. That is, when the processing order is programmed to be performed in alphabetical order from block A to block H, for example, alkaline water or the like can be distributed to the spray nozzle 10 disposed in block B after the sterilization processing of block A is completed. Therefore, the electric valve M in the piping path to the block B is opened by the control unit C, so that the block B is sterilized.

  In this way, sterilization is performed for each block in a predetermined order, and sterilization processing for all blocks is completed. Note that the sterilization of the barn 2 may be set to be performed at an arbitrary number of times per day with a predetermined time interval, or may be programmed to be performed at a frequency of about 2 to 3 times every day, for example. Moreover, the spraying time in each spraying process, the frequency | count of spraying, the density | concentration of electrolyzed water (Effective disinfection time of pH and hypochlorous acid density | concentration), etc. can be set arbitrarily.

  As described above, in this disinfection method, since spraying control is performed in the order of alkaline water, acidic water, alkaline water, and raw water, the permeability of the sterilization target is increased by the first alkaline water spraying, and then the acidic water Sterilization treatment is performed by spraying, and acid water is neutralized by second alkaline water spraying. And finally, the hypochlorous acid remaining by spraying raw water is washed away, so that the sterilization and corrosion prevention treatment in the barn 2 can be performed efficiently.

  Next, a method for disinfecting the entrance / exit 2a of the barn 2 will be described separately from the disinfection in the barn 2 described above.

  First, when a vehicle or a delivery product is carried in or taken out from the entrance 2a of the barn 2, by pressing the alkaline water spraying manual switch S at the entrance 2a, the alkaline water is introduced into the spraying pipe network 3 and arranged at the entrance 2a. In order to allow alkaline water to flow through the spray nozzle 10, the electric valve M of the alkaline water line 3 b in the piping path to the entrance 2 a is opened. Thereby, the alkaline water is washed and sprayed from the spray nozzle 10 only to the entrance / exit 2a. After the predetermined spraying time is over, the manual switch S is turned OFF and the electric valve M is closed.

  Subsequently, by pressing the manual switch S for acidic water spraying, the electric valve M of the acidic water line 3a in the piping path to the entrance 2a is opened, the acidic water is introduced into the spraying piping network 3, and only the entrance 2a is acidic. Water is sprayed from the spray nozzle 10 by sterilization. After the predetermined spraying time is over, the manual switch S is turned OFF, and the electric valve M is closed by the control unit C.

  Furthermore, by pressing the manual switch S for alkaline water spraying again, the electric valve M of the alkaline water line 3b in the piping path to the entrance 2a is opened, alkaline water is introduced into the spraying pipe network 3, and only the entrance 2a is alkaline. Water is neutralized and sprayed from the spray nozzle 10. After the predetermined spraying time is over, the manual switch S is turned OFF, and the electric valve M is closed by the control unit C.

Finally, by pressing the raw water spray manual switch S, the electric valve M of the raw water line 3c in the piping path to the entrance 2a is opened, and the raw water is introduced into the spray pipe network 3, and the raw water is supplied by the potassium carbonate addition device TC. Potassium carbonate is introduced into the line 3c. Thereby, the raw | natural water to which potassium carbonate was added only to the entrance / exit 2a is sprayed from the spray nozzle 10. FIG. After the predetermined spraying time is over, the manual switch S is turned off and the electric valve M is closed. Thereby, the sterilization process at the doorway 2a is completed.
In addition, each electrolyzed water spread | sprinkled is harmless even if it drinks, and when it touches organic substance, it will be reduce | restored to water with time.

  Thus, in this embodiment, since the acidic water and alkaline water to be introduced into the distribution pipe network 3 can be switched by the distribution switching mechanism 4, acidic water containing hypochlorous acid is distributed in the barn 2. After sterilization, the acidic water adhering to the equipment can be neutralized by switching to alkaline water containing OH radicals that are separated and produced in equal amounts with the acidic water. Can be prevented. Moreover, the effect of inhibiting bacterial growth by alkaline water can also be obtained.

  Furthermore, by spraying only alkaline water before the acidic water spraying by the spraying switching mechanism 4, it is possible to obtain an environment that easily penetrates soil, manure, etc. due to the cleaning effect of the alkaline water. It can be done more effectively. In addition, under alkaline conditions after spraying alkaline water, sodium hypochlorite contained in acidic water and nitrogen-based gas such as ammonia are oxidized to form odorless chloramine by the acidic water spraying, thereby obtaining an air deodorizing effect. be able to. Furthermore, there is no need to provide special ventilation equipment or air conditioning equipment, and the equipment cost can be kept low. Moreover, since electrolyzed water is sprinkled directly by spraying, it is possible to directly sterilize excrement, soil, structures, and viruses and bacteria attached to animal bodies.

  Moreover, since the block to spread can be switched arbitrarily, even if there is a restriction | limiting in the production amount of electrolysis water, disinfection is performed for every block according to the production amount, and the whole barn 2 can be disinfected efficiently. Even the small electrolyzed water generating apparatus 1 can disinfect the large livestock barn 2. It is also possible to set the spraying amount for each block, the number of spraying times and the spraying time, the block rotation for spraying, etc. as appropriate, and it is possible to use electrolyzed water efficiently according to the degree of dirt and contamination for each block. it can.

  Further, since the distribution pipe network 3 is disposed at the doorway 2a of the barn 2 so that it can be sprayed, workers, vehicles, delivered products (those that can touch water), etc. entering and exiting the barn 2 can be passed through the doorway 2a. Can be sterilized. Moreover, it can prevent at the entrance / exit 2a that the vehicle etc. which come in and out are corroded by acidic water by individual spraying of alkaline water.

  Moreover, since it is possible to introduce raw water into the spray pipe network 3, it is possible to wash away part of the acidic water remaining after spraying with alkaline water by spraying a sufficient amount of raw water. Moreover, the cooling effect in the livestock barn using the vaporization heat of water can also be acquired by spraying raw | natural water separately. Furthermore, since potassium carbonate can be added to the raw water, there is no obstacle due to drinks, contact, etc., and no harm to livestock is obtained, and the rust prevention effect is obtained by neutralizing remaining hypochlorous acid and forming a rust prevention film. be able to.

In addition, since the air compressor CP is provided as an in-pipe blow mechanism for injecting compressed air into the pipes of the spray piping 3, the acidic water and alkaline water remaining in the spray pipe 3 such as an acidic water line and an alkaline water line are provided. Alternatively, the raw water can be excluded with compressed air, and freezing in a tube in a cold district or the like can be prevented.
In this way, by making the livestock sterilization system a chicken house sterilization system applied to a chicken house, an efficient and low-cost sterilization treatment such as avian influenza virus can be performed.

  In addition, by setting the size of the sprayed particles for maintaining the sterilizing / disinfecting / rust-preventing effect by spraying the acidic water, alkaline water, and raw water to 50 μm or more, it is possible to prevent diffusion of the particles due to natural ventilation, The spraying effect at the location can be maintained. In addition, it is possible to spray within the range of 5 to 10 spraying times per day, supplementing some airborne viruses and bacteria in the air, and floor, soil, manure, living body, building, equipment The virus / bacteria that grows and propagates by adhering to, etc., has the effect of enhancing the sterilizing and disinfecting effect and not giving the environment of proliferation to the remaining viruses and bacteria.

  Furthermore, if there is a basic kit with a supply function including the above-described electrolyzed water generator purification function, storage tank, pumping pump, etc., this livestock sterilization system will add more blocks and supply the electrolyzed water for each block. Since it is a system which sprays directly in 2, it is not necessary to provide special ventilation equipment and air conditioning equipment, and equipment costs can be kept low.

  Further, in the livestock sterilization system, the acid water line 3a, the alkaline water line 3b, the raw water line 3c, the residual water in the block branch pipe, the water droplets adhering to the fine hole nozzle 10 and the like in a cold region. In order to prevent accidents due to freezing, and to prevent spraying due to freezing of residual water in the pipes, the compressed air for blowing by the air compressor CP is sent into the pipes after the spraying of the water of each system, Freezing can be prevented by eliminating the residual water in the pipes through the blown electric valve Ma attached to the pipe ends of the lines 3a, 3b and 3c.

  Next, the function, purpose, and operation of each unit described above will be described in further detail.

{Basic flow mechanism of main barn disinfection system}
In the barn sterilization system of the present embodiment, as described above, as shown in FIGS. 1 and 2, raw water is introduced into the electrolyzed water generating apparatus 1 through the filter F by the piping of the water supply line 5, and a small amount is obtained by the apparatus. The raw water to which sodium chloride is added is electrolyzed and separated into electrolyzed water of acidic water (containing hypochlorous acid) and alkaline water, and stored in acidic water storage tank T0 and alkaline water storage tank T1, respectively. The raw water is stored in the raw water storage tank T <b> 2 through the piping of the direct water supply line 5.

  The stored acidic water is supplied to the main pipe of the acidic water line 3a disposed in the barn 2 via the filter F by the acid-resistant acidic water pump P0, and the alkaline water is filtered to the filter F by the alkaline water pump P1. The raw water is supplied to the main pipe of the alkaline water line 3b arranged in the livestock house 2 through the raw water pressure pump P2 and to the main pipe of the raw water line 3c arranged in the livestock house 2 through the filter F.

  The main pipe of the raw water line 3c is connected to a pipe of a potassium carbonate addition device TC that is a chemical injection pump for adding potassium carbonate. The air compressor CP for anti-freezing blow is connected to the main pipes of the lines 3a, 3b, 3c via the electric valves Mb group. Furthermore, each line 3a, 3b, 3c is provided with a backflow prevention electric valve Mc to each pump. A blow electric valve Ma is provided at the end of the main pipe of each line 3a, 3b, 3c. The main pipe of each line 3a, 3b, 3c is provided with a supply pipe such as a horizontal main pipe with a nozzle for each block in the barn 2 which is a poultry house. Then, by opening or closing the valve group of the electric valve M of the supply mechanism installed at the end of each line 3a, 3b, 3c, either acidic water, alkaline water or raw water is selected, and the side branch pipe 24 with nozzle is selected. The spray is performed for each block in the barn 2.

  In the block, a manual line 20 is provided as a disinfecting mechanism capable of manually cleaning and disinfecting any place in the barn 2. At the end of the horizontal main pipe and the manual line 20 in the block, an electric valve Ma for blowing residual water in the pipe is provided. This electric valve Ma for residual water blow in the pipe is used to prevent freezing and to make the next spraying condition easy. For example, when switching from alkaline water spraying to acidic water spraying, it is possible to spray acid water without taking time. It is used as a device for removing alkaline water remaining in the previously sprayed tube.

{Raw water, filter, electrolyzed water generator, storage tank mechanism}
The raw water used in this system shall be pretreated when well water and river water that do not meet the water quality standards of tap water, including tap water. Dust in the raw water is removed from the piping through the filter F. The filtration degree of the filter F is 200 mesh. Further, two filters F are installed in parallel, and have a mechanism that can be switched and cleaned depending on the degree of dirt, and can be used alternately. Furthermore, the filter medium of the filter F is a cartridge type, and is cleaned and can withstand long-term use.

  The filtered raw water is separated into two directions, and one direction is introduced into the raw water storage tank T2. The raw water storage tank T2 is always kept full of water by a ball tap raw water device (not shown) having an automatic water level maintaining function attached to the tank. The filtered raw water is introduced into the electrolyzed water generating apparatus 1 as another direction. In this electrolyzed water generating apparatus 1, a small amount of sodium chloride (0.1% or less) is mixed in raw water, and the raw water is separated into acidic water and alkaline water containing hypozinc element by electrolysis. The electrolyzed water generating apparatus 1 can select, for example, either 5 L / min generating capacity per minute or 10 L / min per minute depending on the scale of this system.

  As described above, the separated acidic water is stored in the acidic water storage tank T0, and the alkaline water is stored in the alkaline water storage tank T1. A liquid level control device (not shown) associated with each tank senses water reduction in any of the tanks, and automatically operates the electrolyzed water generating device 1 according to an operation instruction for replenishment. It supplies to T0 and the alkaline water storage tank T1 in the ratio of an equal part. In addition, since it operates by the request | requirement of either acidic water or alkaline water, when one tank is in a full condition due to balance, the full tank will naturally overblow. Moreover, when each tank is low in water, the control panel 12 is set to display a low water and issue an alarm buzzer.

The potassium carbonate adding device TC is accompanied by a potassium carbonate storage tank (not shown).

{Anti-freezing function in cold regions}
When the freeze prevention system of the control panel 12 is selected and designated by operation, the freeze prevention operation of the spray nozzle 10 and the freeze prevention operation of the residual water in the pipe are activated in a cold region. That is, when a series of spray cycles of alkaline water spray, acidic water spray, alkaline water spray, and raw water spray on the block is completed, the backflow prevention electric valve Mc provided on the discharge side of the raw water pump P2 is automatically closed. After that, the valve group of the compressed air injection electric valve Mb connected to the main pipe of the raw water line 3c is opened, and the compressed air is sent from the air compressor CP.

  At the same time, the electric valve M, which is a selection mechanism provided at the end of the main pipe of the raw water line 3c, is opened, and the electric valve Ma for blow provided at the end of the branch main pipe of each block is used as a spray cycle. Since it is already open at the end, the residual water in the pipe is automatically drained. Next, after drainage of the residual water in the branch main pipe system and the horizontal branch pipe 24 is completed, the branch main pipe end blow electric valve Ma is closed.
