Organic fertilizer fermentation kettle

According to the technical scheme, the organic fertilizer fermentation kettle is characterized in that the organic fertilizer fermentation kettle comprises a fermentation box body, and the fermentation box body is provided with an air outlet hole; the air delivery pipe is arranged on the inner circular wall surface of the air outlet hole; the deodorization assembly is arranged at one end of the gas conveying pipe and used for deodorizing gas generated by fermentation, the gas generated by organic fertilizer is treated by arranging the deodorization assembly, the gas is filtered by arranging a deodorization box, and the gas enters a deodorization rod through adsorption holes, so that the deodorization effect is achieved. The activated carbon mounted in the deodorization rod is used for adsorbing gas generated by fermentation, the activated carbon can effectively adsorb substances such as fatty acid inorganic sulfur, organic sulfur and ammonia nitrogen in the gas, fine particles in the gas can be filtered throu
