Description

  The present invention relates to a deodorizing system for a poultry house, and more particularly to a deodorizing system for a poultry house effective for deodorizing various odors generated from a poultry house in a poultry farm.

  Generally, in poultry farms, the odor of chicken manure discharged from poultry houses (especially the odor generated when chicken manure is fermented) diffuses to the surrounding area, affecting the living environment of people working and living in the area. Therefore, measures such as incineration, carbonization, composting, etc. and deployment of a deodorizing device are taken to prevent the odor of chicken manure from spreading to the surrounding area.

  However, in the poultry farm, in order to keep the temperature and humidity in the poultry house constant, a ventilation fan is installed on the roof and walls of the poultry house, and the house is ventilated by driving the ventilation fan or by natural convection. However, the odors of raw chicken manure (before fermentation treatment), chicken body odor, food odor, etc. discharged from the poultry house by ventilation are slight compared to the odors generated during composting fermentation of chicken manure. As a result, it is often left untreated.

By the way, in recent years, the scale of poultry farms has increased, and chicken farms of a scale that raises over 1 million chickens are not uncommon. In such large scale farms, for example, about 100,000 chickens are raised. Since there are 10 or more possible poultry houses, if the air volume required for ventilation per poultry house is about 7000 (m ³ / min), the air volume required for ventilation of the poultry house in the entire poultry farm is about 70000 (m ³ / min).

  For this reason, since the hen house ventilates a large amount of complex odors such as the odor of raw chicken manure (before fermentation), the body odor of the chicken, and the odor of the food from the poultry house, it is becoming a situation where these odors cannot be ignored. These odors may spread to the surrounding area and affect the living environment of people who work and live in the area.

  The present invention has been made in view of the above problems, and a complex odor such as the odor of raw chicken manure (before fermentation treatment) discharged from a poultry house, the body odor of chicken, and the odor of food is present in the surrounding area. The purpose is to provide a deodorization system for poultry houses that does not spread and does not deteriorate the living environment of people who work and live in the area.

In order to solve the above problems, the present invention employs the following means.
That is, according to the present invention, a chicken house is provided with a cage for raising chickens and a collection means for collecting chicken manure discharged from the cage, and a ventilation means for ventilating the inside of the chicken house. The odor system is provided with an injection pipe for injecting deodorant gas toward the chicken dung collected by the collection means in the poultry house, and connected to a deodorant gas supply source for supplying the deodorant gas to the injection pipe It is characterized by that.

According to the deodorizing system for a poultry house of the present invention, the deodorizing gas is injected from the injection tube toward the chicken droppings collected by the collecting means, so that the smell of the chicken droppings, the body odor of the chicken in the cage, the food in the feeding device Combined odors such as odors can be eliminated.
In this case, install the injection pipe so that the deodorized gas is directly injected to the source of odor such as odor of chicken manure, body odor of chicken in cage, food odor in feeding device, etc. Therefore, those odors can be efficiently deodorized.
In addition, by installing an injection pipe so that the deodorized gas can be directly injected from a close distance toward the chicken odor, which has the strongest odor in the poultry house, The odor of the chicken in the cage and the odor of the food in the feeding device can be deodorized by the remaining capacity of the deodorizing gas drifted around this area. Can be prevented from being affected by medicinal properties.
In addition, the deodorant gas is sprayed toward the source of odor, so the deodorant directly adheres to chickens and eggs, as in the case of spraying a mist-like deodorant toward the source of odor. As a result, the skin and eyes of chickens are not adversely affected, the smell of the deodorant adheres to the eggs, and the medicinal components of the deodorant do not penetrate into the eggs.
Therefore, without affecting the chickens, food, and eggs in the cage, the combined odors such as the odor of chicken manure, the body odor of the chicken, and the odor of the food that are discharged from the house by ventilation in the house are efficiently removed. Since it can be made light, it is possible to prevent those odors from spreading to the surrounding area and affecting the living environment of people working and living in that area.

  Moreover, in this invention, it is good also as connecting the air blower which supplies external air to the said injection pipe.

According to the deodorization system for a poultry house of the present invention, deodorant gas is supplied from the deodorant gas supply source to the injection pipe, and outside air is supplied from the blower to the injection pipe. Thus, the mixture of the deodorant gas and the outside air can be sprayed toward the chicken manure collected by the collecting means. Therefore, combined odors such as the odor of chicken manure discharged from the poultry house, the body odor of chicken, and the odor of food can be deodorized and the drying of chicken manure can be promoted.
In addition, in the poultry house, when an injection pipe for injecting outside air toward the chicken manure is already installed, by using this existing injection pipe, by connecting a deodorant gas supply source to this injection pipe, Without installing a new injection pipe, the existing injection pipe is used to inject a mixture of deodorized gas and outside air toward the chicken manure, and the odor of chicken manure, chicken body odor and food odor discharged from the poultry house It is possible to deodorize complex odors such as, and to promote drying of chicken manure.

  Furthermore, in this invention, while providing the injection pipe which injects external air toward the chicken droppings collect | recovered by the said collection | recovery means in the said poultry house, it is good also as connecting the air blower which supplies external air to this injection pipe.

  According to the deodorization system for a chicken house of the present invention, the odor of chicken manure, the body odor of chicken, Combined odors such as odors are eliminated, and drying of chicken droppings is promoted by spraying the outside air through the injection pipe for injecting outside air toward the chicken droppings collected by the collecting means.

  Furthermore, in this invention, while the said collection | recovery means is provided under the said cage, it is good also as being a belt conveyor which can store the chicken manure discharged | emitted from the said cage in the upper part.

  According to the deodorizing system for a poultry house of the present invention, the chicken droppings discharged from the cage is stored at the upper part of the belt conveyor, and the deodorizing gas is jetted from the injection pipe toward the chicken droppings. In this case, the deodorizing gas eliminates combined odors such as the odor of chicken manure, the body odor of chicken and the odor of food, and the flow of the deodorizing gas promotes drying of the chicken manure to some extent. In addition, when a mixture of deodorant gas and outside air is injected from the deodorant tube, the mixture of deodorant gas and outside air creates a complex odor such as odor of chicken manure, body odor of chicken, and odor of food. While deodorizing, drying of chicken manure is promoted. Furthermore, when the deodorizing gas is injected from the injection pipe and the outside air is injected from the injection pipe separate from the deodorizing gas, the odor of the chicken manure, the body odor of the chicken, the odor of the food, etc. is mixed by the deodorizing gas. In addition to being deodorized, drying of chicken manure is promoted by outside air.

  Furthermore, in this invention, while the said collection | recovery means is provided under the said cage, it is good also as being the space which can store the chicken manure discharged | emitted from the said cage.

  According to the deodorization system for a poultry house according to the present invention, chicken droppings discharged from the cage are stored in a space provided below the cage, and deodorizing gas is jetted from the injection pipe toward the chicken droppings. Combined odors such as odor, chicken body odor and food odor are eliminated.

  Furthermore, in the present invention, the deodorizing gas is normally liquid, solid or granular, and may be gasified before being injected from the injection tube toward the chicken manure.

  According to the chicken house deodorizing system of the present invention, the deodorizing gas is normally in a liquid, solid or granular form and is gasified before being injected from the injection tube toward the chicken droppings. Combined odors such as food odors are eliminated.

As described above, according to the deodorization system for a poultry house according to the present invention, the deodorizing gas and the outside air are injected by deodorizing gas from the injection pipe toward the chicken manure collected by the collecting means, or from the injection pipe. The mixed odor such as the odor of chicken manure, the body odor of chicken, the odor of food, etc. can be deodorized by jetting the mixed gas.
Therefore, even if complex odors such as chicken manure odor, chicken body odor, food odor, etc. are discharged together with exhaust from the poultry house by ventilation of the poultry house, those odors can be reduced. Even if the odor spreads to the surrounding area, it does not affect the living environment of people working and living in that area. Moreover, since drying of chicken droppings can be accelerated | stimulated, the efficiency at the time of processing the collected chicken droppings with a composting fermentation processing apparatus etc. can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 6 show a first embodiment of a chicken house deodorization system according to the present invention. The deodorization system for a poultry house according to the present embodiment is applied to a poultry farm equipped with a low-floor type poultry house. When ventilating the poultry house, raw chicken manure (fermented) is discharged along with the exhaust from the poultry house. It is effective for deodorizing odors such as odor before treatment, body odor of chicken, and odor of food.

  The low-floor type chicken house 1 is, for example, formed in a two-story structure having a width of 15 m, an eave height of 10 m, and a length of about 100 m, as shown in FIGS. 1 to 6. 1 is provided on the back side (right side of FIG. 1) with an exhaust port 3, and the intake port 2 is provided with a cooling pad 4 (a pad through which water flows when the temperature exceeds a set temperature). A ventilation fan 5 is provided at the mouth 3 as a ventilation means. In this type of poultry house 1, for example, about 100,000 chickens per house can be raised.

Further, in the above-described poultry house 1, by driving the ventilation fan 5, outside air of about 2000 to 6000 (m ³ / min) is appropriately adjusted according to the season and is sucked into the poultry house 1 from the air inlet 2. The gas flows through the inside in the direction of the arrow in FIG. Thereby, the inside of the poultry house 1 is ventilated, and the temperature and humidity in the poultry house 1 are appropriately adjusted according to the season and kept constant.

  Further, for example, as shown in FIGS. 4 to 6, a cage 11 (a wire net-like bird cage) having a predetermined size is stacked on the first floor portion 6 and the second floor portion 7 of the chicken house 1 in four stages. Each of the cages 11 is configured to be able to accommodate a predetermined number of chickens.

  In this case, as shown in FIG. 5, the cage group 10a in the first row and the cage group 10b in the second row, the cage group 10c in the third row, the cage group 10d in the fourth row, and the cage group 10e in the fifth row. And the sixth row cage group 10f are in close contact with each other, between the first row cage group 10a and the wall surface 8 of the poultry house 1, between the second row cage group 10b and the third row cage group 10c, A passage 9 having a predetermined width is formed between the cage group 10d in the fourth row and the cage group 10e in the fifth row, and between the cage group 10f in the sixth row and the wall surface 8 of the poultry house 1, respectively. Cage groups 10a to 10f are provided in six rows on the first floor portion 6 and the second floor portion 7 of the poultry house 1, respectively.

  As shown in FIGS. 5 and 6, on the outer surface 12 of each cage 11, there are a feeding device 13 that feeds chickens in each cage 11, and an egg collection device 14 that collects eggs discharged from each gauge 11. However, a water supply port (not shown) of a water supply facility for supplying drinking water to the chickens in each cage 11 is provided in the longitudinal direction of each cage 11. It is provided at a plurality of locations at predetermined intervals in the direction.

  Below each cage 11, as shown in FIGS. 4 to 6, a belt conveyor 16 that is a collection means for collecting chicken droppings wider than the entire width of each cage 11 extends over the entire length of each cage 11. And it is provided rotatably so that a predetermined gap is formed between the lower surface of each cage 11, and is configured to collect and carry out the chicken manure discharged from each cage 11 by this belt conveyor 16.

  In this embodiment, each belt conveyor 16 is driven periodically (for example, every 3 to 7 days), so that the chicken manure collected by each belt conveyor 16 is composted on the site of the poultry farm. It is periodically carried into a fermentation treatment apparatus (not shown) and processed. In addition, the driving | operation space | interval of each belt conveyor 16 can be suitably set according to the scale of the poultry house 1, etc.

  As shown in FIGS. 5 and 6, an injection tube 20 having a plurality of injection holes 21 is provided in the center of the lower surface of each cage 11 so as to extend over the entire length of each cage 11. The deodorizing gas supply source 26 provided outside the poultry house 1 is connected via distribution pipes 22 provided at both ends or the center of the poultry house 1.

  By driving the deodorant gas supply source 26, the deodorant gas is supplied from the deodorant gas supply source 26 into the distribution pipe 22, and this deodorized gas is supplied to each injection pipe 20 through the distribution pipe 22. It sprays toward the poultry manure of the upper part of each belt conveyor 16 from the injection hole 21 of each injection pipe 20. FIG.

  As the deodorizing gas, those capable of deodorizing and deodorizing chicken odor, chicken body odor, food odor and the like can be used. However, if it touches the skin, enters the eye, or is accidentally ingested, it must be safe and harmless in any case.

  In addition, the deodorizing gas is not limited to the gaseous state, and is normally liquid, solid, or granular, and until it is jetted from the jet holes 21 of the jet pipes 20 toward the chicken droppings on the belt conveyor 16. It may be gasified. However, it is necessary to confirm in advance that the egg is not affected by the residual odor of the deodorant gas.

  By spraying deodorant gas from the injection holes 21 of each injection pipe 20 toward the chicken droppings at the top of the belt conveyor 16, the deodorizing gas is directly injected into the chicken droppings, and the odor generated from the chicken droppings is deodorized. The drying of chicken manure is promoted to some extent. In addition, the deodorizing gas that has deodorized the chicken manure drifts around, so that the body odor generated from the chicken in the cage 11, the odor generated from the food in the feeding device 13, the food and water spilled around the chicken Odor such as odor is eliminated.

  In the poultry house deodorizing system of the present embodiment configured as described above, an injection pipe 20 is provided at the center of the lower surface of each cage 11 so as to correspond to the chicken droppings on the upper part of the belt conveyor 16. By injecting the deodorizing gas from the injection hole 21 of the pipe 20 toward the chicken droppings at the top of the belt conveyor 16, it is possible to deodorize combined odors such as the odor of chicken droppings, the body odor of chicken, and the odor of food. Moreover, the drying of chicken manure can be promoted to some extent by the flow of the deodorizing gas.

  Therefore, in order to keep the inside of the poultry house 1 at a constant temperature and humidity, even if a large amount of outside air is introduced into the poultry house 1 to ventilate the poultry house 1, the odor of chicken manure discharged along with the exhaust from the poultry house 1 Complex odors such as chicken's body odor and food odor can be reduced, so even if those odors spread to the surrounding area, it will affect the living environment of people working and living in that area. There is no such thing as giving.

  Moreover, since the drying of chicken droppings can be accelerated to some extent by the flow of deodorizing gas by injecting the deodorizing gas onto the chicken droppings on the upper part of the belt conveyor 16, the collected chicken droppings are composted and fermented (not shown). ), It is possible to increase the processing efficiency in the case of performing a fermentation process, or in the case of performing a carbonization process or an incineration process.

In the present embodiment, since the ventilation power of the poultry house 1 is set to approximately 6000 ^(m 3 / min), the odorless been odorous gas from the poultry house 1 to about 6000 ^(m 3 / min) is discharged become. The amount of odorous gas discharged from the poultry house 1 changes according to the season in order to adjust the temperature and humidity. For example, in summer when the temperature and humidity are high, the cooling pad is operated to turn the ventilation fan 4 into a strong wind. A large amount of odorous gas is discharged by using it in the winter, and in winter when the temperature and humidity are low, a small amount of odorous gas is discharged by using the ventilation fan 4 in a weak wind without operating the cooling pad. It will be.

  FIG. 7 shows a second embodiment of the deodorization system for a poultry house according to the present invention. The deodorization system for a poultry house according to the present embodiment supplies deodorant gas and outside air to each injection pipe 20, and mixes the deodorized gas and outside air from the injection holes 21 of each injection pipe 20 to the belt conveyor 16.
