Description

Technical Field

[0001] This application relates to the field of pigsty deodorization systems, and particularly to an external exhaust gas deodorization system for pigsties. Background Art

[0002] During the daily use of pigsties, a large amount of odor is often generated and discharged. If no targeted treatment is carried out, it will cause great pollution to the air. In the existing related technologies, the external exhaust gas of pigsties is generally deodorized through a fan and a water curtain. That is, the external exhaust gas in the pigsty is pumped out by the fan and blown towards the water curtain. The water curtain is formed by stacking plastic water curtain plates with concave and convex surfaces on both sides and having a large number of through holes. A deodorizing reagent such as hydrogen peroxide solution is sprayed on the water curtain through a sprayer, so that the deodorizing reagent stays in the holes inside the water curtain, and then there is a large reaction area between the deodorizing reagent and the external exhaust gas, thereby removing the odor of the external exhaust gas of the pigsty through the chemical reaction between the deodorizing reagent and the external exhaust gas.

[0003] Specifically, reference can be made to the invention patent with the publication number CN 116724896 A, which discloses a closed-loop pigsty biological deodorization circulation system, including a pigsty, a deodorization buffer room, a deodorization biological filler wall, and a deodorization spray component. The deodorization buffer room is connected to the pigsty to discharge the pigsty odor. The deodorization biological filler wall is arranged at the air outlet end of the deodorization buffer room, and the deodorization spray component is arranged on the side of the deodorization biological filler wall to cooperate with the deodorization biological filler wall and the deodorization spray component for deodorization; one end of the input end of the deodorization circulating water treatment component is connected to the closed pigsty through a circulating water pipe to circulate the deodorization treatment wastewater of the closed pigsty, and the output end of the deodorization circulating water treatment component is connected to the closed pigsty through a circulating water supply component to send the treated purified water into the closed pigsty to realize circulation.

[0004] Regarding the above related technologies, when the sprayer sprays the deodorizing reagent on the water curtain, the deodorizing reagent is easily forced through the water curtain under the action of water pressure and the fan and does not stay in the holes inside the water curtain. As a result, some of the deodorizing reagent falls to the ground in the external environment behind the water curtain after passing through the water curtain, causing waste, and there is a problem of low utilization rate of the deodorizing reagent. Summary of the Invention

[0005] In order to improve the utilization rate of the deodorizing reagent when deodorizing the external exhaust gas of the pigsty, this application provides an external exhaust gas deodorization system for pigsties.

[0006] The external exhaust gas deodorization system for pigsties provided by this application adopts the following technical solutions: An external exhaust gas deodorization system for pigsties includes a deodorization room, an exhaust fan, an atomizing sprayer, and a deodorization water curtain. The exhaust fan, the atomizing sprayer, and the deodorization water curtain are all located in the deodorization room; The exhaust fan is used to blow the odor in the pigsty towards the deodorizing water curtain, and the atomizing sprayer is used to spray the deodorizing reagent. The included angle between the nozzle of the atomizing sprayer and the vertical direction is 0° to 60°. The deodorizing water curtain is a porous structure. The front of the deodorizing water curtain faces the exhaust fan, and the rear of the deodorizing water curtain faces the external environment.

[0007] By adopting the above technical solution, the exhaust fan blows the odor in the pigsty towards the deodorizing water curtain, and the atomizing sprayer atomizes and sprays the deodorizing reagent. After the deodorizing reagent is atomized and sprayed out from the atomizing sprayer, a deodorizing reagent water mist wall is formed, thereby increasing the contact area between the deodorizing reagent and the exhaust gas. After the exhaust gas fully contacts and reacts with the deodorizing reagent in the water mist wall, the first-round deodorization of the exhaust gas is completed.

[0008] In addition, after the deodorizing reagent is atomized and sprayed out from the atomizing sprayer, it also moves towards the deodorizing water curtain under the action of the wind force of the exhaust fan, thereby making it easier for the deodorizing reagent to stay in the holes inside the deodorizing water curtain and reducing the situation where part of the deodorizing water machine passes through the deodorizing water curtain under the action of water pressure, resulting in the underutilization of some deodorizing reagents. Therefore, when deodorizing the exhaust gas from the pigsty, the utilization rate of the deodorizing reagent is improved.

[0009] Optionally, the horizontal distance between the atomizing sprayer and the deodorizing water curtain is 60 cm to 180 cm.

[0010] By adopting the above technical solution, an atomizing deodorization area is formed between the atomizing sprayer and the deodorizing water curtain, increasing the contact time between the deodorizing reagent water mist and the exhaust gas, and enabling the deodorizing reagent water mist to fully contact the exhaust gas in the atomizing deodorization area, thereby further ensuring the deodorization effect.

[0011] Optionally, a spray return groove is provided in the deodorizing chamber. The spray return groove is located at the bottom of the atomizing sprayer, and the spray return groove is connected to the atomizing sprayer through a water pump.

[0012] By adopting the above technical solution, after the deodorizing reagent water mist contacts the exhaust gas, it moves towards the spray return groove and is then transported to the atomizing sprayer for secondary utilization, improving the utilization rate of the deodorizing reagent.

[0013] Optionally, the deodorizing water curtain includes a water curtain frame and a deodorizing module. The water curtain frame is installed on the deodorizing module. There are several deodorizing modules, and several deodorizing modules are all detachably installed on the water curtain frame. The deodorizing module is used to install the water curtain plate.

[0014] By adopting the above technical solution, when the deodorizing water curtain needs to be cleaned and replaced in some areas (especially the top and bottom), the deodorizing modules in these areas can be removed, and then the corresponding areas of the deodorizing water curtain can be cleaned targeted, reducing the situation of cleaning and replacing the relatively large-volume deodorizing water curtain, thereby reducing the difficulty of cleaning and replacing the deodorizing water curtain. Therefore, the problem that when the deodorizing reagent is atomized and sprayed out from the atomizing sprayer, due to the relatively large initial velocity, it is not easy to contact the top of the deodorizing water curtain, or due to the relatively strong wind, it is not easy to contact the bottom of the deodorizing water curtain, resulting in the top and bottom of the deodorizing water curtain being more likely to be blocked or polluted and yellowed by the exhaust gas is solved.

[0015] Optionally, a plurality of module slots are formed in the water curtain frame, and the plurality of deodorizing modules are respectively horizontally slidably fitted in the respective module slots.

[0016] By adopting the above technical solution, when the deodorizing module needs to be disassembled, only horizontal pushing and pulling of the deodorizing module is required to remove the deodorizing module, which is convenient and fast.

[0017] Optionally, the plurality of module slots communicate with each other in the vertical direction in sequence, a water curtain return groove is formed in the deodorizing chamber, the water curtain return groove is located at the bottom of the water curtain frame, and the water curtain return groove is connected to the atomizing sprayer through a water pump.

[0018] By adopting the above technical solution, the deodorizing reagent staying inside the deodorizing module gradually flows downward under the action of gravity into the water curtain return groove, and is conveyed to the atomizing sprayer again through the water curtain return groove and the water pump for secondary utilization, improving the utilization rate of the deodorizing reagent.

[0019] Optionally, a plurality of water curtain plates are provided in the deodorizing module, and the plurality of water curtain plates are stacked in sequence in the vertical direction. The materials of the plurality of water curtain plates are all plastics. The deodorizing module is provided with a bottom cross bar, and the bottom cross bar supports the water curtain plates inside the deodorizing module from the bottom.

[0020] By adopting the above technical solution, the bottom cross bar supports the water curtain plates of the deodorizing module, making it not easy for each water curtain plate to bend and generate a large deflection, reducing the situation that the concave and convex parts at the bottom of the upper water curtain plate bend and catch the concave and convex parts at the top of the lower water curtain plate, resulting in difficulty in pushing and pulling out the deodorizing module.

[0021] Optionally, the deodorizing module is provided with a top cross bar, and the top cross bar is horizontally pluggably fitted to the top of the deodorizing module.

[0022] By adopting the above technical solution, when the water curtain plates of the deodorizing module need to be replaced, pulling out the top cross bar can take out the water curtain plates from the inside of the deodorizing module, which is convenient and fast.

[0023] Optionally, a rotation driving member is installed in the deodorization chamber, and the rotation driving member is used to drive the atomizing sprayer to rotate towards or away from the deodorization water curtain.

[0024] By adopting the above technical solution, the rotation driving member periodically or non-periodically rotates the atomizing sprayer, thereby adjusting the nozzle orientation of the atomizing sprayer, so that the atomizing sprayer can perform supplementary spraying on the top or bottom of the deodorization water curtain, ensuring the deodorization effect at the top and bottom of the deodorization water curtain, and also making it not easy for the top and bottom of the deodorization water curtain to turn yellow, increasing the maintenance period.

[0025] Optionally, a rotating seat is installed in the deodorization chamber, the atomizing sprayer is rotationally matched with the rotating seat, the type of the rotation driving member is a cylinder, and the two ends of the rotation driving member are respectively rotationally matched with the inner wall of the deodorization chamber and the atomizing sprayer.

[0026] By adopting the above technical solution, the rotation driving member extends or retracts the piston rod to drive the atomizing sprayer to rotate, and the structure is relatively reliable.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The exhaust fan blows the odor in the pigsty towards the deodorization water curtain, and the atomizing sprayer performs atomizing spraying of the deodorizing reagent. After the deodorizing reagent is atomized and sprayed out from the atomizing sprayer, a deodorizing reagent water mist wall is formed, thereby increasing the contact area between the deodorizing reagent and the exhaust gas. After the exhaust gas fully contacts and reacts with the deodorizing reagent in the water mist wall, the first-round deodorization of the exhaust gas is completed; In addition, after the deodorizing reagent is atomized and sprayed out from the atomizing sprayer, under the action of the wind force of the exhaust fan, it moves towards the deodorization water curtain, and then the deodorizing reagent is more likely to stay in the holes inside the deodorization water curtain, reducing the situation that part of the deodorizing reagent is not fully utilized due to the deodorizing water machine passing through the deodorization water curtain under the action of water pressure, so as to improve the utilization rate of the deodorizing reagent when deodorizing the exhaust gas from the pigsty; 2. When a part of the deodorization water curtain (especially the top and bottom) needs to be cleaned and replaced, the deodorization module in this area is removed, and then the area of the deodorization water curtain can be cleaned targeted, reducing the situation that the relatively large deodorization water curtain needs to be cleaned and replaced, thereby reducing the difficulty of cleaning and replacing the deodorization water curtain. Therefore, the problem that when the deodorizing reagent is atomized and sprayed out from the atomizing sprayer, due to the relatively large initial velocity, it is not easy to contact the top of the deodorization water curtain, or due to the relatively large wind force, it is not easy to contact the bottom of the deodorization water curtain, making the top and bottom of the deodorization water curtain more likely to be blocked or polluted and turn yellow by the exhaust gas is solved; 3. The rotation driving member periodically or aperiodically rotates the atomizing sprayer, thereby adjusting the nozzle orientation of the atomizing sprayer, so that the atomizing sprayer can perform supplementary spraying on the top or bottom of the deodorizing water curtain, ensuring the deodorizing effect at the top and bottom of the deodorizing water curtain, and also making it difficult for the top and bottom of the deodorizing water curtain to turn yellow, increasing the maintenance period.

Detailed Embodiment

[0036] The following will Figure 1-8 further describe the present application in detail.

[0037] The embodiment of the present application discloses a pig house exhaust gas deodorization system. Refer to Figure 1 and Figure 2, the odor removal system for the exhaust gas outside the pigsty includes an odor removal chamber 1, an exhaust fan 2, an atomizing sprayer 3, and an odor removal water curtain 4. The odor removal chamber 1 is made of reinforced concrete, and the odor removal chamber 1 is located between the pigsty (not shown in the figure) and the external environment. Moreover, the exhaust fan 2, the atomizing sprayer 3, and the odor removal water curtain 4 are all located inside the odor removal chamber 1. Additionally, in this application, the external environment refers to the outdoor environment that is outside the pigsty and the odor removal chamber 1 and is directly connected to the atmosphere.

[0038] Referring to Figure 1 and Figure 2 , the exhaust fan 2 is located on the side of the odor removal chamber 1 close to the pigsty, and the exhaust fan 2 is fixedly installed on the side wall of the odor removal chamber 1, and the exhaust fan 2 is arranged facing the external environment. The air inlet end of the exhaust fan 2 is communicated with the pigsty to facilitate extracting the odor in the pigsty. The number of the exhaust fans 2 can be adjusted accordingly according to the scale of the pigsty, and multiple exhaust fans 2 can be arranged in one row or multiple rows.

[0039] Referring to Figure 1 and Figure 2 , the odor removal water curtain 4 is located on the side of the odor removal chamber 1 close to the external environment to facilitate the exhaust fan 2 blowing the odor in the pigsty towards the odor removal water curtain 4. Combining Figure 3 , the odor removal water curtain 4 includes a water curtain frame 41 and several odor removal modules 42. The water curtain frame 41 extends in the horizontal direction, and the bottom of the water curtain frame 41 is fixedly installed on the ground of the odor removal chamber 1, and the top of the water curtain frame 41 is fixedly installed on the top plate of the odor removal chamber 1. The water curtain frame 41 is fixedly connected with several partition cross frames 411. The several partition cross frames 411 are divided into several columns, and the distribution direction of the several columns of partition cross frames 411 is consistent with the extension direction of the water curtain frame 41. The several partition cross frames 411 in each column are distributed in the vertical direction, and a module slot 401 is formed between the upper and lower adjacent partition cross frames 411. The module slot 401 runs through horizontally, and the module slots 401 formed by each column of partition trusses are interconnected to facilitate the downward flow of the odor removal reagent located at the top.

[0040] Referring to Figure 4 and Figure 5 , a sealing gasket 412 is fixedly installed on the side of the partition cross frame 411 facing the module slot 401. The sealing gasket 412 has elasticity, and the sealing gasket 412 is preferably made of rubber to reduce the gap between the odor removal module 42 and the module slot 401 through the sealing gasket 412 after the odor removal module 42 is inserted into the module slot 401, thereby ensuring that more odor passes through the odor removal module 42 for odor removal.

[0041] Referring to Figure 2 and Figure 6, a plurality of deodorization modules 42 are all rectangular frame structures, and the plurality of deodorization modules 42 are respectively slidably fitted in the respective module slots 401 in the horizontal direction, so as to facilitate the installation of the deodorization modules 42 in the module slots 401 or the extraction of the deodorization modules 42 from the module slots 401. A plate placing cavity 402 is formed by enclosing the deodorization modules 42, and the plate placing cavity 402 is used for installing the water curtain plates. The water curtain plates are made of plastic, and a plurality of through holes are formed through the water curtain plates to increase the surface area of the water curtain plates. In addition, in the present application, a plurality of water curtain plates are provided, and the plurality of water curtain plates are stacked in sequence in the vertical direction in the plate placing cavity 402, so that a plurality of through holes are also formed between two adjacent upper and lower water curtain plates.

[0042] Referring to Figure 6 and Figure 7 , three bottom cross bars 421 are provided at the bottom of the deodorization module 42. The three bottom cross bars 421 are distributed along the length direction of the deodorization module 42, and there is a gap between the three bottom cross bars 421. The three bottom cross bars 421 jointly support the water curtain plates from the bottom of the plate placing cavity 402, so that the bottom of the water curtain plates is not likely to have a large deflection, reducing the situation that the water curtain plates in the upper and lower two deodorization modules 42 block each other and affect the extraction and insertion of the deodorization modules 42. In addition, the three bottom cross bars 421 are connected to each other through a bottom connecting plate, and a bottom handle is also fixedly connected to the bottom connecting plate, so as to facilitate the simultaneous extraction of the three bottom cross bars 421 and facilitate the wiping and cleaning of the bottom cross bars 421.

[0043] Three top cross bars 422 are provided at the top of the deodorization module 42. The three top cross bars 422 are distributed along the length direction of the deodorization module 42, and there is a gap between the three top cross bars 422. The three top cross bars 422 are connected to each other through a top connecting plate, and a top handle is also fixedly connected to the top connecting plate, so as to facilitate the simultaneous extraction of the three top cross bars 422 and facilitate the wiping and cleaning of the top cross bars 422.

[0044] Referring to Figure 2 , a water curtain return groove 101 is formed at the bottom of the deodorization chamber 1. The water curtain return groove 101 is located at the bottom of the deodorization water curtain 4, and the water curtain return groove 101 communicates with the respective module slots 401, so as to facilitate the deodorization reagent in the respective module slots 401 to fall back into the water curtain return groove 101. The water curtain return groove 101 is connected to the input end of an external deodorization reagent generator 5 through a pipeline and a water pump, so as to facilitate the recycling of the deodorization reagent by the deodorization reagent generator 5 and the secondary recycling of the deodorization reagent. In addition, in the embodiment of the present application, the deodorization reagent is a hydrogen peroxide solution.

[0045] Referring to Figure 2, the atomizing sprayer 3 is used for atomizing and spraying the deodorizing reagent, and the input end of the atomizing sprayer 3 is connected to the output end of the deodorizing reagent generator 5 through a hose and a water pump, so as to facilitate the deodorizing reagent generator 5 to transport the deodorizing reagent to the atomizing sprayer 3.

[0046] Refer to Figure 2 and Figure 8 , a rotation driving member 11 and a rotating seat 12 are provided at the top of the deodorizing chamber 1. The rotating seat 12 is fixedly installed at the top of the deodorizing chamber 1. The atomizing sprayer 3 is rotationally fitted to the rotating seat 12. The type of the rotation driving member 11 is a cylinder, and the rotation driving member 11 is provided with aerodynamic force by an external air compressor (not shown in the figure). The two ends of the rotation driving member 11 are respectively rotationally fitted to the inner wall of the top of the deodorizing chamber 1 and the atomizing sprayer 3, so as to facilitate the rotation driving member 11 to extend or retract the piston rod, driving the atomizing sprayer 3 to rotate towards or away from the deodorizing water curtain 4, so as to make the atomized deodorizing reagent contact the deodorizing modules 42 at different heights.

[0047] The horizontal distance between the atomizing sprayer 3 and the deodorizing water curtain 4 is 60 cm to 180 cm. Specifically, the horizontal distance between the atomizing sprayer 3 and the deodorizing water curtain 4 refers to: the horizontal distance between the nozzle axis of the atomizing sprayer 3 and the front side of the deodorizing water curtain 4. By moving the atomizing sprayer 3 away from the deodorizing water curtain 4, an atomizing deodorizing area is formed between the atomizing sprayer 3 and the deodorizing water curtain 4, thereby increasing the contact time between the deodorizing reagent water mist and the exhaust gas, and enabling the deodorizing reagent water mist to fully contact the exhaust gas in the atomizing deodorizing area, thus further ensuring the deodorizing effect.

[0048] The included angle between the atomizing sprayer 3 and the vertical direction is 0° to 60°, and the atomizing sprayer 3 rotates on the side close to the deodorizing water curtain 4, so as to contact and react with the odor before the deodorizing reagent water mist reaches the deodorizing water curtain 4, thereby ensuring the deodorizing effect on the exhaust gas. In addition, a top inclined surface is provided at the top of the deodorizing chamber 1, and the top inclined surface is inclined downward towards the deodorizing water curtain 4, so as to facilitate the deodorizing reagent water mist atomized by the atomizing sprayer 3 to reach the deodorizing module 42 located at the top, so that the deodorizing module 42 located at the top is not easily yellowed.

[0049] The deodorization chamber 1 is provided with a spray return trough 102. The spray return trough 102 is located at the bottom of the atomizing sprayer 3. The spray return trough 102 is connected to the deodorization generator through a water pump and a pipeline, so as to facilitate the collection of the deodorization reagent through the spray return trough 102, and the deodorization reagent generator 5 conveys the recycled and regenerated deodorization reagent to the atomizing sprayer 3. In addition, the deodorization chamber 1 is also provided with two diversion slopes 103. The two diversion slopes 103 are respectively located on both sides of the spray return trough 102, and the diversion slopes 103 incline towards the spray return trough 102 from top to bottom, so as to guide more deodorization reagents that fall back to the ground of the deodorization chamber 1 into the spray return trough 102, and improve the utilization rate of the deodorization reagent.

[0050] The implementation principle of the pig house exhaust gas deodorization system in the embodiment of the present application is as follows: The exhaust fan 2 blows the odor in the pig house towards the deodorization water curtain 4, and the atomizing sprayer 3 atomizes and sprays the deodorization reagent. After the deodorization reagent is atomized and sprayed out from the atomizing sprayer 3, a deodorization reagent water mist wall is formed at the top of the spray return trough 102, and an atomizing deodorization area is formed between the spray return trough 102 and the deodorization water curtain 4. The deodorization reagent water mist wall comes into contact with the exhaust gas blown out by the exhaust fan 2 to complete the first deodorization. Subsequently, during the movement of the exhaust gas towards the deodorization water curtain 4, it continues to come into full contact with the deodorization reagent water mist in the atomizing deodorization area, thereby completing the secondary deodorization.

[0051] After the exhaust gas passes through the deodorization reagent water mist wall and the atomizing deodorization area in sequence, it will reach the inside of the deodorization water curtain 4. The exhaust gas reacts with the deodorization reagent retained in the water curtain plate in the deodorization module 42 to complete the third deodorization, so that the odor in the exhaust gas is preferably removed and then discharged to the external environment.

[0052] During the three - stage deodorization process, the deodorization reagent will be recycled to the deodorization reagent generator 5 through the spray return trough 102 and the water curtain return trough 101. The deodorization reagent generator 5 re - uses the recycled deodorization reagent and conveys the newly generated deodorization reagent to the atomizing sprayer 3, thereby improving the utilization rate of the deodorization reagent.

[0053] Moreover, after the deodorization reagent is atomized and sprayed out from the atomizing sprayer 3, it moves towards the deodorization water curtain 4 under the action of the wind force of the exhaust fan 2. As a result, the deodorization reagent is more likely to remain in the holes inside the deodorization water curtain 4, reducing the situation that the deodorization water machine passes through the deodorization water curtain 4 under the action of water pressure, resulting in some deodorization reagents not being fully utilized. Thus, when deodorizing the pig house exhaust gas, the utilization rate of the deodorization reagent is further improved.

[0054] In addition, when the atomizing sprayer 3 atomizes and sprays the deodorizing reagent, it rotates periodically within an angle range of 0° to 60°, so that the deodorizing reagent atomized and sprayed by the atomizing sprayer 3 can more easily reach the water curtain plates in the deodorizing modules 42 at the top and bottom of the deodorizing water curtain 4, thereby making it difficult for the water curtain plates to adhere and accumulate dirt and turn yellow, and thus reducing the occurrence of the situation where the deodorizing water curtain 4 is blocked due to dirt accumulation and needs to be disassembled and cleaned.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
