DETAILED DESCRIPTION

[0021] For the convenience of those skilled in the art to understand, the utility model is described in further detail below in combination with the drawings and specific embodiments.

[0022] As Figure 1 shown, an organic fertilizer fermentation greenhouse, including shed 100, the shed 100 is used for fertilizer fermentation, the shed 100 is equipped with exhaust pipe group 200, the exhaust pipe group 200 includes gas collection section 210, the end of gas collection section 210 is communicated with the gas guide section 220, the end of gas guide section 220 is communicated with the deodorization section 230, and the one end of deodorization section 230 is equipped with exhaust port 270.Gas collection section 210 is used to uniformly and comprehensively extract the waste gas in shed 100, and gas guide section 220 is used to guide the waste gas extracted in gas collection section 210 to deodorization section 230 for processing, and exhaust port 270 finally discharges the processed gas.In the embodiment, the top of one end of gas collection section 210 is communicated with the bottom of one end of gas guide section 220, and the deodorization section 230 is located at the other end of gas guide section 220, and this layout mode can reduce the overall length of exhaust pipe group 200, and facilitate the application of exhaust pipe group 200 in small fermentation shed.

[0023] As Figure 1 shown, the bottom of gas collection section 210 is equipped with a plurality of air inlets 211, the air inlet 211 is used for waste gas to enter, and the air inlet 211, gas guide section 220 and exhaust port 270 are all equipped with exhaust equipment 400, the air outlet of exhaust equipment 400 on the air inlet 211 faces into gas collection section 210, the air outlet of exhaust equipment 400 in gas guide section 220 faces deodorization section 230, and the air outlet of exhaust equipment 400 in exhaust port 270 faces the outlet of exhaust port 270.Through the cooperation of each exhaust equipment 400, a complete and effective gas path is formed in exhaust pipe group 200: the exhaust equipment 400 on the air inlet 211 sucks the waste gas in shed 100 into gas collection section 210, and the exhaust equipment 400 in gas guide section 220 sucks the waste gas in gas collection section 210 into deodorization section 230 for processing, and finally the exhaust equipment 400 in exhaust port 270 discharges the gas.Exhaust equipment 400 provides power for the flow of waste gas, and in practical application, exhaust equipment 400 can be selected from fan and exhaust fan and other equipment.

[0024] As Figure 2 , 3As shown, the upper part of the deodorization section 230 is provided with a plurality of overflow tanks 240, and the upper part of the overflow tank 240 is provided with a water supply pipe 250 for supplying water to the overflow tank 240. The water supply pipe 250 includes a main pipe 251, and the main pipe 251 is provided with a plurality of water outlets 252, each of which corresponds to an overflow tank 240 to supply water to the overflow tank 240. The top of the deodorization section 230 is provided with openings 231 corresponding to the overflow tanks 240, and the deodorization section 230 is provided with a plurality of filter plate groups 300 corresponding to the openings 231. The overflow tank 240 is a U-shaped tank, and the two ends of the overflow tank 240 are curved downward outside the tank. When the water supply pipe 250 fills the overflow tank 240 with water, the water will flow down from the two ends of the overflow tank 240 and form an even water curtain, and the water curtain will fall evenly on the filter plate group 300 through the opening 231. Each two adjacent openings 231 correspond to the two ends of an overflow tank 240, and one overflow tank 240 can supply water to two filter plate groups 300, which can improve the uniformity of water supply to a plurality of filter plate groups 300. The upper part of the deodorization section 230 is also provided with a cover 260, and the water supply pipe 250 and the overflow tank 240 are located in the cover 260, which can prevent the exhaust gas from diffusing to the outside through the opening 231. It should be noted that the main odor component of the exhaust gas generated by the organic fertilizer is ammonia and other gases that are easily soluble in water, so the deodorization of the exhaust gas is realized by the contact between water and the exhaust gas in this embodiment. The filter plate group 300 in this embodiment is the main component for fully contacting the exhaust gas with water. In actual application, different liquids can be replaced to realize the treatment of different exhaust gases.

[0025] As Figure 2 、 4As shown in Figure 5, the air filter plate assembly 300 includes multiple air filter plates 310 arranged from top to bottom, with each air filter plate 310 spaced apart and arranged in opposite directions. The top end of each lower air filter plate 310 is higher than the bottom end of each upper air filter plate 310, and the top end of each lower air filter plate 310 is located on the side facing the bottom end of the upper air filter plate 310. This allows the water flowing down from the upper air filter plate 310 to flow evenly onto the surface of the lower air filter plate 310, forming a complete water curtain on the entire air filter plate assembly 300, thus achieving the filtration of exhaust gas. Simultaneously, compared to ordinary straight plates, the air filter plate assembly 300 has a larger gas contact area, which can improve the filtration effect of exhaust gas. The filter plate 310 includes a perforated plate 311, and a mesh 312 is provided on the side of the perforated plate 311 that is in contact with water. The perforated plate 311 and the mesh 312 are important components in forming a water curtain. The structure of the filter plate 310 is designed based on the influence of liquid surface tension. When water flows over the surface of the mesh 312 and the perforated plate 311, a uniform and dense water curtain is formed. When the exhaust gas passes through the openings in the perforated plate 311, it can effectively come into contact with the water, achieving the purpose of deodorization. At the same time, some water will drip from the openings in the perforated plate 311, further increasing the contact area between water and exhaust gas.

[0026] like Figure 2 As shown, a water tank 232 is provided below the air filter plate assembly 300. The water tank 232 is connected to a drain pipe 233. The treated water can be collected and discharged through the water tank 232 and the drain pipe 233. In practice, a circulation device can also be arranged to connect the drain pipe 233 and the water supply pipe 250, so that the water can be circulated for use until a certain condition is met before being discharged for treatment, thereby reducing water waste. In this embodiment, the bottom of the air guiding section 220 and the exhaust port 270 are both higher than the bottom of the deodorization section 230. A water tank 232 is formed between the bottom of the deodorization section 230 and the bottom of the air guiding section 220, and between the bottom of the deodorization section 230 and the bottom of the exhaust port 270. One side of the water tank 232 is connected to the drain pipe 233. In this embodiment, there is no need to set up other components to form a water tank 232 in the deodorization section 230. Instead, the connection between the deodorization section 230 and the exhaust port 270 and the connection between the deodorization section 230 and the air guide section 220 are directly utilized, which can effectively save production and installation costs.

[0027] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
