Biological organic fertilizer fermentation deodorization device

The invention relates to a biological organic fertilizer fermentation deodorization device. The biological organic fertilizer fermentation deodorization device is provide with a fermentation library,wherein a vacuum negative pressure meter is arranged in the fermentation library, and an odor outlet is formed in the top 1 / 3-1 / 2 of the fermentation library, and the odor outlet is provided with an induced draft fan, a gas valve for adjusting the air flow conveniently is arranged between the odor outlet and the induced draft fan, a deodorization tower is arranged at an outlet of the induced draftfan, a chimney is arranged at the top of the deodorization tower, a sampler is arranged in the middle of the chimney, an adsorption section filled with activated carbon is arranged on the middle partof the deodorization tower, partition plates used for fixing the activated carbon are arranged at the bottom and the top of the adsorption section, through holes are formed in the partition plates, the diameter of the through holes is smaller than the diameter of the activated carbon, a discharge hole is formed in the lower part of the adsorption section, a material filling hole is formed in theupper part of the adsorption section, the discharging hole is arranged opposite to the material filling hole, and an air inlet pipe is arranged on the lower part of the discharging hole. The biological organic fertilizer fermentation deodorization device is simple in structure, ingenious in design and good in deodorization effect. The pollution of odor to the living environment is effectively avoided, and good application and promotion prospects are achieved.
