Description

Technical Field

[0001] The utility model relates to the technical field of livestock manure and planting waste treatment, and particularly relates to a manure fermentation deodorization house. Background Art

[0002] The manure fermentation deodorization house converts livestock manure into organic fertilizer through biodegradation and deodorization technology, while reducing or eliminating its malodorous smell and harmful components. This kind of facility is of great significance in the environmental protection field of the breeding industry, and helps to realize the resource utilization of manure and environmental protection. The processes of the manure fermentation deodorization house mainly involve the pretreatment of manure, the fermentation process, the deodorization treatment, and the subsequent treatment and other links. In the fermentation process, aerobic composting, turning, temperature control, and deodorization and other processes are required.

[0003] Chinese patent document CN214693818U discloses a factory-style chicken manure fermentation treatment device applicable to chicken farms, including a shed body with a roof and columns. Inside the shed body, along the length direction of the shed body, there is a fermentation tank for fermenting chicken manure. The fermentation tank includes two vertically and oppositely arranged tank walls on both sides. The space between the two tank walls forms the tank body of the fermentation tank. Inside the fermentation tank body, near the bottom, there is a conveying chain for conveying chicken manure; inside the fermentation tank body and at the bottom, a plurality of aeration pipes are arranged side by side; it also includes a biological deodorization device. The biological deodorization device absorbs waste gas from the fermentation tank through a plurality of suction pipelines arranged on the fermentation tank body. The biological deodorization device is an integrated tank-type gas treatment device with a plasma generator and / or a biological deodorizer, and collects and treats the gas in the storage bin and the gas discharged after fermentation through the plasma method or the biological method and discharges it up to standard to avoid secondary pollution to the surrounding environment; the aeration pipes are laid perpendicular to the length direction of the fermentation tank to ensure sufficient aeration in the whole fermentation tank, and the aeration pipes are provided with heating devices inside, and the aeration temperature is controlled through the heating devices.

[0004] The existing technology has the following deficiencies: In the existing technology, a heating device needs to be separately arranged inside the aeration pipe to provide heat for fermentation, and a separate deodorization device is arranged to absorb waste gas from the fermentation tank for exhaust. The area of the fermentation plant is large, and arranging multiple sets of heating devices will increase the cost of the deodorization device. Summary of the Utility Model

[0005] The utility model provides a manure fermentation and deodorization house which is convenient for composting fermentation heating and deodorization of manure residue and breeding wastewater and has low cost, including a fermentation house and a deodorization device. A fermentation bed is arranged at the bottom of the fermentation house. It is characterized in that the fermentation house is of a sealed structure. A water collecting tank is arranged under the fermentation bed. A cover filter plate is arranged on the water collecting tank. An odor pipeline is arranged at the upper part of the fermentation house. The odor pipeline is communicated with an exhaust fan and a heat exchanger. The heat exchanger is communicated with the deodorization device. Odor enters the deodorization device after passing through the heat exchanger and is discharged through an exhaust pipeline. A cold air inlet pipeline and a hot air outlet pipeline are arranged on the heat exchanger. The hot air outlet pipeline is communicated with an aeration pipeline laid in the water collecting tank.

[0006] For the convenience of aeration fermentation, a plurality of strip-shaped water collecting tanks are longitudinally or transversely arranged in the fermentation bed, and the aeration pipeline is arranged in each water collecting tank.

[0007] For the convenience of exhaust deodorization and heat exchange, the odor pipeline includes a main pipeline and a plurality of branch pipelines. One end of the plurality of branch pipelines is simultaneously communicated with the main pipeline. The number and distribution of the branch pipelines are the same as those of the aeration pipeline.

[0008] Furthermore, the other ends of the plurality of branch pipelines are simultaneously communicated by a connecting pipeline, and an air inlet facing downwards is arranged at the bottom of the branch pipeline.

[0009] Furthermore, a turning machine is arranged in the fermentation house. The turning machine is connected to a moving track. The moving track is supported by left and right support columns on both sides of the fermentation bed. Turning can make the moisture, temperature, oxygen, etc. of the compost reach uniformity through turning, stirring and other methods, and can also play the roles of supplying air, mixing materials and emitting water vapor.

[0010] For the convenience of sewage discharge, the water collecting tank is communicated with a sewage discharge pipe. The sewage discharge pipe is communicated with a sewage circulation pool. The sewage circulation pool is connected with a manure storage tank through a water pump and can be re-sprinkled on the fermentation material, so as to adjust the moisture content of the fermentation material and ensure the smooth progress of aerobic composting.

[0011] Furthermore, the water collecting tank is inclined. The sewage circulation pool is located at the lowest side of the water collecting tank. The hot air outlet pipeline is located at the highest side of the water collecting tank.

[0012] The utility model has the following beneficial effects:

[0013] The deodorizing fermentation effect is good, the overall structure is simple, and the cost is low. The hot air at the top in the closed fermentation chamber is sent to the heat exchanger by the exhaust fan, the heat is absorbed by the external cold air, and then discharged to the deodorizing device in time after condensation. The odor is then purified and discharged through the deodorizing device. The cold air outdoors increases in heat after heat exchange and is conveyed to the interior of the aeration pipeline, and aerates from the bottom of the fermentation bed. On the one hand, it provides oxygen for the fermentation material and sufficient oxygen for aerobic microorganisms, which is beneficial for the microorganisms to maintain better activity and dominant flora, ensuring the smooth progress of aerobic fermentation; on the other hand, the hot air provides temperature for the fermentation chamber from bottom to top, ensuring uniform fermentation of the manure residue. The increase in heat can ensure that the fermentation process maintains a high temperature state, ensuring the smooth completion of the fermentation work of the fermentation bed.
