Biological organic fertilizer fermentation deodorization device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to a biological organic fertilizer fermentation and deodorization device. Background technique [0002] With the continuous development of the breeding industry and people's increasing awareness of environmental protection, the recycling of poultry manure is becoming more and more urgent. Therefore, it has become a common popularization mode to use poultry and livestock manure for bio-fermentation and degradation to process into bio-organic fertilizer. Bio-organic fertilizer is a kind of microbial fertilizer and organic fertilizer compounded by combining specific functional microorganisms with animal and plant residues (such as livestock and poultry manure, crop straw, etc.) Fertilizer with fertilizer effect. Compared with the most common chemical fertilizers at present, bio-organic fertilizers (1) bio-organic fertilizers have complete nutrients, while c...

Problems solved by technology

[0003] However, bio-organic fertilizers are often accompanied by a large amount of malodorous gas in the process of composting anaerobic fermentation or aerobic fermentation. The odor mainly contains fatty acids, amines, aromatics, inorganic sulfur, organic sulfur and ammonia nitrogen. The odor will attract flies and rodents. At the same time, the odor will bring a certain degree of pollution to the living environment of the surrounding residents. It will cause nausea, vomiting and irritability in a short period of time. memory loss and cardiovascular disease
