Description
Technical Field
[0001] The utility model relates to the technical field of cow dung organic fertilizer fermentation, in particular to an exhaust device for cow dung organic fertilizer fermentation. Background Technique
[0002] Cow dung organic fertilizer is an organic fertilizer made from cow dung as the main raw material, through a series of treatment processes and adding other organic substances for fermentation. To avoid excessive internal air pressure during the fermentation process of cow dung organic fertilizer, it is necessary to discharge the gas generated by cow dung fermentation through an exhaust device. Some exhaust devices include a base and a deodorization mechanism. By setting a deodorization mechanism on the left side of the top surface of the base, under the action of an odor extraction fan, the odor enters the deodorization box along the air delivery pipe. The activated carbon layer on the top surface of the support net preliminarily deodorizes the odor, and the calcium oxide layer on the top of the activated carbon layer further dehumidifies and deodorizes the odor, completing the purification treatment of the odor, thereby realizing the exhaust and deodorization operation of the gas generated by the fermentation of cow dung organic fertilizer. However, a large amount of biogas is generated during the fermentation process of cow dung organic fertilizer. After being deodorized and filtered, these biogas are discharged into the external environment, resulting in the unreasonable utilization of gas resources and waste, which needs to be improved.

The gas generated during the fermentation of cow dung organic fertilizer enters the filter shell 7 through the connecting pipe 6 after combustion, and is multi-stage filtered through the multi-layer activated carbon filter layer 8 to separate the internal impurities. Then the gas is discharged to the external environment through the air outlet pipe 9, and the filter net 10 is used to prevent impurities in the external gas from entering the inside of the air outlet pipe 9 or the gas supply pipe 52;
[0022] Combustion heat recovery mechanism 5: It includes an igniter 51, a gas supply pipe 52, and a heating water pipe 54.
