Description

Technical Field

[0001] The invention relates to the technical field of breeding equipment, and in particular to a deodorization system and method for livestock and poultry houses. Background Art

[0003] During the livestock and poultry breeding process, livestock and poultry feces, urine, sewage, etc. in the livestock and poultry houses will produce a lot of odor. If the odor of the livestock and poultry houses is not handled properly, it will often lead to odor complaints from the surrounding areas, which will affect the normal production of the livestock and poultry farms. Moreover, these odors will stimulate the olfactory nerves of livestock and poultry, thereby affecting the respiratory center and respiratory function. These odors are even toxic. Long-term existence will reduce the immunity of livestock and poultry, weaken their physical fitness, make them prone to illness, and reduce their production performance. Therefore, it is very important to deodorize the odor of livestock and poultry houses. In order to reduce the impact of the livestock and poultry breeding process on the surrounding areas and livestock and poultry, the demand for odor control measures in the livestock and poultry industry is extremely urgent.

[0004] Although there are many cases or patents for deodorization of livestock and poultry houses at home and abroad, most of them are currently set up on the fan wall side of the livestock and poultry house. Deodorization is carried out in the deodorization room by atomization equipment or circulating spraying filler wall deodorization. Atomization or spraying deodorization uses gas-liquid contact reaction, but if the gas-liquid contact is to be sufficient, a large amount of atomization or water needs to be provided. Therefore, there are disadvantages such as large water consumption, high energy consumption of atomization or spraying equipment, and high operating cost, and often even the expected deodorization effect is not achieved.

[0005] To this end, based on the deodorization characteristics of livestock and poultry houses and the premise of ensuring production safety, we need to design a deodorization system and method for livestock and poultry houses to overcome the shortcomings of existing deodorization. Summary of the invention

[0006] In view of the above problems, the present invention adopts a deodorization process combining gas-gas exchange and gas-liquid exchange and further optimizes the structure of the dust reduction and deodorization room, thereby solving the problems of dust reduction, hair blocking and deodorization in livestock and poultry houses.

[0007] According to one aspect of the present invention, a deodorization system for livestock and poultry houses is provided, comprising livestock and poultry houses, dust reduction and deodorization rooms and gasification and deodorization units, wherein a plurality of livestock and poultry houses are arranged side by side in the longitudinal direction, a plurality of fans are arranged on the outer walls of the livestock and poultry houses, the dust reduction and deodorization rooms are arranged adjacent to the plurality of livestock and poultry houses and are connected through the fans, the gasification and deodorization units comprise interconnected deodorant gasification equipment and gasification pipelines, the gasification pipelines are located in the livestock and poultry houses, an atomization unit is arranged in the dust reduction and deodorization room, the atomization unit comprises a first atomization device and a second atomization device, the first atomization device is arranged on the outer longitudinal surface of the fan, the second atomization device is arranged at the top of the dust reduction and deodorization room, both sides of the dust reduction and deodorization room are air outlets, the odor of the livestock and poultry houses and the gasification deodorant output by the gasification and deodorization unit are mixed and deodorized by the fan impeller, and then discharged into the dust reduction and deodorization room through the fan, the atomization unit sprays atomized liquid to increase the weight of dust and feathers, reduce dust and block feathers, and further deodorize. The beneficial effect is that the gasification deodorization unit gasifies the deodorant and conveys it to the gasification pipeline in the livestock and poultry house, and uses the livestock and poultry house fan impeller to mix it, so as to achieve sufficient gas mixing and exchange of the livestock and poultry house odor and the gasification deodorant, thereby achieving the first-level deodorization of the livestock and poultry house odor by the gasification deodorant; the gas after the first-level deodorization is discharged into the dust reduction and deodorization room through the fan, and the atomized liquid is sprayed through the first atomization device on the longitudinal surface outside the fan and the second atomization device on the top of the dust reduction and deodorization room, so as to drop the dust and feathers in the gas discharged into the dust reduction and deodorization room, and The gas discharged into the dust reduction and deodorization room is subjected to second-stage deodorization and third-stage deodorization in sequence, thus achieving three-stage deodorization. The three-stage deodorization overcomes the problems of the existing deodorization. The present invention utilizes a gasification deodorization unit to output a gasification deodorant, thereby achieving sufficient gas-to-gas exchange and deodorization between the odor of the livestock and poultry house and the gasification deodorant, which greatly saves at least 50% of the deodorant usage and water usage in the dust reduction and deodorization room. Combined with the fully connected through-type dust reduction and deodorization room and the gas-liquid exchange deodorization of the atomization unit, the deodorization effect can be effectively guaranteed, and the influence of the odor of livestock and poultry breeding on the outside world is completely solved.

[0008] In some embodiments, the gasification pipeline is arranged inside the fan in the livestock and poultry house and corresponds to the middle position of the fan, and a plurality of gas outlets are arranged on the gasification pipeline.

[0010] In some embodiments, the dust reduction and deodorization room is a through-type dust reduction and deodorization room. The beneficial effect is that the dust reduction and deodorization rooms at the ends of the fans of multiple livestock and poultry houses are all connected, and the dust reduction and deodorization rooms are all connected through-type dust reduction and deodorization rooms, which greatly increases the overall space of the dust reduction and deodorization room, prolongs the reaction time of gas-liquid exchange in the dust reduction and deodorization room, and buffers the impact on the ventilation of the livestock and poultry houses.

[0015] In some embodiments, the windshield is further provided with a switchable door, which is arranged opposite to the fan. The beneficial effect is that the switchable door serves as an emergency ventilation measure to ensure production safety in extremely hot weather.

[0016] According to another aspect of the present invention, there is provided a deodorizing method for livestock and poultry houses, comprising the following steps:

[0017] Start the gasification deodorization unit: start the deodorant gasification equipment to gasify the deodorant and transport it to the gasification pipeline in the livestock and poultry house at a distance of 15 to 25 cm from the fan. Use the fan impeller to mix the gasification deodorant and the livestock and poultry house odor to fully mix and exchange gas, so as to achieve the deodorization of the livestock and poultry house odor by the gasification deodorant.

[0018] Start the atomization unit: start the first atomization device set at 15 to 25 cm away from the fan in the dust reduction and deodorization room, the second atomization device set at the top of the dust reduction and deodorization room, and the third atomization device set at the top of the outlet extension area, spray the liquid supplied by the liquid supply device into fine mist, and use the fan to provide power.

[0019] Start the spray device: By starting the spray device installed on the top of the packing wall, the packing wall can be sprayed cyclically to increase the ventilation of the dust reduction and deodorization room;

[0020] Prolong the reaction time: After the odor from the livestock and poultry house is deodorized by the gasification deodorizer, it is discharged from the livestock and poultry house into the dust reduction and deodorization room through the fan. The dust reduction and deodorization room adopts a multi-building interconnected method, which greatly prolongs the reaction time between the deodorizer and the odor. The odor discharged into the dust reduction and deodorization room is treated by the first atomization device and the second atomization device in turn, and finally treated by the third atomization device at the top of the outlet extension area or the spray device at the top of the filler wall before being discharged;

[0021] Dealing with extremely hot weather: When encountering extremely hot weather, the switchable door of the dust reduction and deodorization room can be opened to speed up the air circulation in the livestock and poultry house, prevent the livestock and poultry in the livestock and poultry house from heatstroke, and ensure production safety.

[0022] Beneficial effects of the present invention:

[0023] 1. The present invention provides a gasification deodorization unit and an atomization unit, so that the odor of the livestock and poultry house can be deodorized by gas exchange with the gasification deodorant output by the gasification deodorization unit, and then the atomized liquid sprayed by the atomization unit in the dust reduction and deodorization room can be further deodorized by gas-liquid exchange, which can effectively ensure the deodorization effect.

[0024] 2. The present invention gasifies the deodorant through a deodorant gasification device, and the gasified deodorant is then transported to the front end of the fan in the livestock and poultry house through a gasification pipeline, and the impeller of the livestock and poultry house fan is used to mix the gasified deodorant and the livestock and poultry house odor, thereby achieving the deodorization of the livestock and poultry house odor by the gasified deodorant. Compared with gas-liquid exchange, this gas-to-gas exchange can capture the odor more fully, so the deodorization effect is better; most importantly, compared with the atomization deodorant, the gasification deodorant method not only greatly saves the required amount of medicine, but also the gas-to-gas exchange greatly improves the gas-liquid exchange effect, so the deodorization effect is better, thereby greatly reducing the energy consumption and operating cost of the subsequent atomization unit, thereby saving water. Compared with the original atomization deodorization system, the amount of medicine and water can be saved by at least 50%.

[0025] 3. The present invention can achieve further gas-liquid exchange deodorization by arranging a first atomizing device on the outer longitudinal surface of the fan in the dust reduction and deodorization room, a second atomizing device at the top of the dust reduction and deodorization room, and a third atomizing device at the top of the air outlet extension area, and supplying clean water or water with deodorant added to the atomizing device through a liquid supply device. The atomizing device mainly relies on the sprayed droplets to increase the weight of dust and feathers to enhance the dust reduction and feather blocking effects, and can also further enhance the deodorization effect of water-soluble odors through gas-liquid exchange.

[0026] 4. The present invention designs the dust reduction and deodorization rooms at the ends of the fans of multiple houses into fully connected through-type dust reduction and deodorization rooms, which greatly increases the overall space of the dust reduction and deodorization rooms, prolongs the reaction time of gas-liquid exchange in the dust reduction and deodorization rooms, and buffers the impact on the ventilation of livestock and poultry houses; and outlet extension areas are set at the air outlets on both sides, and a third atomization device is configured at the top to further promote gas-liquid contact and enhance the deodorization effect.

[0027] 5. The present invention arranges a filler wall on the windshield on the front of the dust reduction and deodorization room, and the filler wall is arranged opposite to the aisle between every two livestock and poultry houses. The ventilation of the dust reduction and deodorization room can be increased by circulating spraying the filler wall; a switchable door is also arranged on the windshield, and the switchable door is arranged opposite to the middle fan of each livestock and poultry house. When encountering extremely high temperature weather, opening the switchable door can improve the rapid ventilation and cooling of the livestock and poultry houses, providing an important safety emergency measure for livestock and poultry production.

DETAILED DESCRIPTION

[0034] The present invention will be further described in detail below in conjunction with the embodiments.

[0035] Example 1

[0036] refer to Figure 1 to Figure 5The present invention provides a deodorization system for livestock and poultry houses, comprising a livestock and poultry house 1, a dust reduction and deodorization room 5, and a gasification deodorization unit. The livestock and poultry house 1 has a plurality of buildings (≤5 buildings) arranged side by side in the longitudinal direction, and a plurality of fans 2 are arranged on the outer wall of the livestock and poultry house 1. The gasification deodorization unit comprises a deodorant gasification device 3 and a gasification pipeline 4 which are connected. The deodorant gasification device 3 is arranged on the side outside the livestock and poultry house 1 at the end of the fan 2 of the livestock and poultry house 1. The gasification pipeline 4 is installed in the livestock and poultry house 1 at a distance of 20 cm from the fan and corresponds to the middle position of the fan 2. The gasification pipeline 4 is provided with a plurality of gas outlets 401. The deodorant gasification equipment 3 gasifies the deodorant, and then transports the gasified deodorant to the front end of the fan of the livestock and poultry house 1 (specifically, the middle of each fan 1) through the gasification pipeline 4. The impeller of the fan 2 mixes the odor of the livestock and poultry house 1 with the gasified deodorant for gas exchange, thereby achieving the deodorization of the odor of the livestock and poultry house 1 by the gasified deodorant. The deodorant is mainly a volatile organic plant deodorant.

[0037] A plurality of interconnected dust removal and deodorization rooms 5 are built on the outer wall side of the livestock and poultry house 1. The dust removal and deodorization rooms 5 are adjacent to the plurality of livestock and poultry houses 1 and are connected through the fan 2. The dust removal and deodorization rooms 5 are interconnected dust removal and deodorization rooms 5. The two sides of the dust removal and deodorization rooms 5 are air outlets, and each extends 10m to form an air outlet extension area 21. An atomization unit is arranged in the dust removal and deodorization room 5, and the atomization unit includes a first atomization device, a second atomization device and a third atomization device. The first atomization device is arranged on the longitudinal surface 20cm away from the fan outside the fan 2, the second atomization device is arranged at the top of the dust removal and deodorization room 5, and the third atomization device is arranged at the top of the air outlet extension area 21. The dust removal and deodorization rooms 5 at the ends of the fans 2 of the plurality of livestock and poultry houses 1 are all connected, which greatly expands the dust removal space, effectively extends the deodorization time, thereby improving the dust removal and deodorization efficiency, and effectively buffers the impact on the ventilation of the livestock and poultry houses 1.

[0038] The first atomizing device includes a first atomizing pipe 11, which is arranged on the outer longitudinal surface of the fan 2. The second atomizing device includes a second atomizing pipe 12, which is arranged at the top of the dust reduction and deodorization room 5. The third atomizing device includes a third atomizing pipe 13, which is arranged at the top of the air outlet extension area 21. A plurality of atomizing nozzles 22 are arranged on the first atomizing pipe 11, the second atomizing pipe 12 and the third atomizing pipe 13. The first atomizing pipe 11, the second atomizing pipe 12 and the third atomizing pipe 13 are all connected to the liquid outlet of the liquid supply device. The liquid supply device is arranged on the corridor between two adjacent livestock and poultry houses 1. The two adjacent livestock and poultry houses 1 share a set of liquid supply devices, which include a dosing barrel 7, a dosing pump 6, a filter 8, a water bucket 9 and a liquid supply pump 10. The dosing barrel 7 is connected to the water bucket 9 through a pipeline in which the dosing pump 6 and the filter 8 are installed in sequence. The water bucket 9 is connected to the first atomizing pipeline 11, the second atomizing pipeline 12 and the third atomizing pipeline 13 through a pipeline in which the liquid supply pump 10 is installed. Specifically, the deodorant (the deodorant is a chemical deodorant, a plant deodorant or a composite deodorant) or clean water in the dosing barrel 7 is filtered by the dosing pump 6 and the security filter 8, enters the water bucket 9, mixes the water and the deodorant, and then passes through the first atomizing pipeline 11, the second atomizing pipeline 12 and the third atomizing pipeline 13 through the liquid supply pump 10 to spray out to the longitudinal atomizing nozzle 22 and the top atomizing nozzle 22.

[0039] A light-transmitting PVC rainproof board 16 is fixed on the top of the dust-removing and deodorizing room 5, which effectively prevents a large amount of rainwater from entering the dust-removing and deodorizing room 5 on rainy days. The front of the dust-removing and deodorizing room 5 is a light-transmitting PVC windshield 17, on which a packing wall 15 is arranged, the packing wall thickness is 45cm, and the packing wall 15 is arranged opposite to the aisle between every two livestock and poultry houses 1. A spray device is arranged on the top of the packing wall 15, and a circulating water tank 18 is arranged at the bottom of the packing wall 15. The spray device is connected to the circulating water tank 18 through a pipeline equipped with a circulating water pump 19. Specifically, the spray device includes a spray pipe 20, and the water outlet holes or water outlet gaps on the multiple spray pipes 20 are staggered, specifically, a 5mm water outlet hole is drilled every 10cm on the spray pipe 20. The circulating water tank 18 is clean water or water with added deodorant (the deodorant is a chemical deodorant, a microbial deodorant, a plant deodorant or a composite deodorant), which is replaced every 7-10 days according to actual conditions. The circulating water pump 19 pumps water from the circulating water tank 18 to the top spray pipe 20 for 24 hours. The spray liquid is evenly and continuously circulated and sprayed from the top of the packing wall 15 for deodorization. The purpose is to serve as a supplementary measure for the air outlet on both sides of the dust reduction and deodorization room 5. The odor deodorized by the dust reduction and deodorization room 5 can also be discharged after being deodorized by the packing wall 15. Because the packing wall 15 is a porous material and can be ventilated, it is required to circulate and spray for 24 hours to keep the exhaust gas of the livestock and poultry house 1 purified and discharged in time, so it will not affect the ventilation of the livestock and poultry house 1, and can fully ensure the production safety of livestock and poultry in high temperature areas. A switchable door 14 is also provided on the windshield 17. The switchable door 14 is arranged opposite to the middle fan 2 of each livestock and poultry house 1. The switchable door 14 is closed on a daily basis and is only opened in an emergency when the temperature is extremely high. It is used to prevent the rapid ventilation of the livestock and poultry house 1 in extremely high temperature weather, and serves as an emergency ventilation measure to ensure production safety in extremely high temperature weather.

[0040] The atomizing unit is used to spray atomized deodorizing liquid, which can increase the weight of dust and feathers, improve the dust reduction and hair blocking effects, and on the basis of the first-stage deodorization of the livestock and poultry house 1 by the gasified deodorant, the clean water or water with deodorant sprayed by the atomizing nozzle 22 on the outer longitudinal surface of the fan 2 is used for the second-stage deodorization, and then the odor that comes out continues to extend the reaction time in the dust reduction and deodorization room 5, and at the same time, the atomizing nozzle 22 on the top of the dust reduction and deodorization room 5 continues to spray clean water or water with deodorant for the third-stage deodorization, dust reduction, hair blocking and deodorization again. Finally, the gas deodorized by the third stage is discharged after being treated by the atomizing nozzle 22 on the top of the outlet extension area 21 or the spray device on the top of the filler wall 15, to ensure that the exhaustable gas has no impact on the surrounding environment.

[0041] The present invention utilizes a gasification deodorization unit to output a gasification deodorant to the front end of a fan in a livestock and poultry house 1, thereby achieving sufficient gas-to-gas exchange and odor reduction between the odor of the livestock and poultry house 1 and the gasification deodorant, greatly saving the amount of deodorant and water used in the dust reduction and deodorization room 5, saving at least 50%. When the air pressure is low, the gas-liquid exchange of the fully connected through-type dust reduction and deodorization room 5 and the atomization unit is combined to further reduce dust, hair and odor, thereby improving the deodorization effect, completely solving the impact of livestock and poultry breeding odor on the outside world, and highlighting the significant advantages of the present invention in deodorization efficiency, energy saving and environmental protection, and ease of operation.

[0042] Example 2

[0044] Start the gasification deodorization unit: start the deodorant gasification device 3, gasify the deodorant and transport it to the gasification pipeline 4 in the livestock and poultry house 1, which is 20 cm away from the fan, and use the impeller of the fan 2 to mix the deodorant. The odor of the livestock and poultry house 1 and the gasification deodorant are fully mixed and exchanged, so that the gasification deodorant can reduce the odor of the livestock and poultry house 1;

[0045] Start the atomization unit: by starting the first atomization device arranged at 20 cm from the fan in the dust reduction and deodorization room 5, the second atomization device arranged at the top of the dust reduction and deodorization room 5, and the third atomization device arranged at the top of the air outlet extension area 21, the liquid supplied by the liquid supply device is sprayed into fine mist, and the fan 2 is used to provide power. The atomization will increase the weight of the dust and feathers in the gas that has been deodorized by the gasified deodorant and discharged into the dust reduction and deodorization room 5, thereby achieving further dust reduction, feather blocking and deodorization;

[0046] Start the spray device: by starting the spray device arranged on the top of the packing wall 15, the ventilation of the dust reduction and deodorization room 5 can be increased by circulating the spraying of the packing wall 15;

[0047] Prolonging the reaction time: After the odor of the livestock and poultry house 1 is deodorized by the gasification deodorant, it is discharged from the livestock and poultry house 1 into the dust reduction and deodorization room 5 through the fan 2. The dust reduction and deodorization room 5 adopts a multi-building interconnected mode, which greatly prolongs the reaction time between the deodorant and the odor. The odor discharged into the dust reduction and deodorization room 5 is processed by the first atomization device and the second atomization device in turn, and finally processed by the third atomization device at the top of the outlet extension area 21 or the spray device at the top of the filler wall 15 before being discharged;

[0048] Dealing with extremely hot weather: When encountering extremely hot weather, the switchable door 14 of the dust reduction and deodorization room 5 can be opened to speed up the air circulation in the livestock and poultry house 1, prevent the livestock and poultry in the livestock and poultry house 1 from heatstroke, and ensure production safety.
