Description

Technical Field

[0001] The utility model relates to the technical field of biological organic fertilizer production equipment, in particular to a waste gas treatment device for biological organic fertilizer. Background Art

[0002] Bio-organic fertilizer refers to a type of fertilizer that has both the effects of microbial fertilizer and organic fertilizer, which is composed of specific functional microorganisms and organic materials that are mainly sourced from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. In the process of bio-organic fertilizer fermentation by specific functional microorganisms, the specific functional microorganisms can decompose large molecular organic matter into simple compounds, which will produce a large amount of ammonia and hydrogen sulfide in this process. In addition, livestock and poultry manure itself contains a large amount of harmful gases, such as ammonia, hydrogen sulfide, skatole, methane, etc., which makes the bio-organic fertilizer produce a large amount of unpleasant and irritating gases during the fermentation process, which will seriously affect the surrounding environment.

[0003] According to Chinese patent CN 219879512 U, a waste gas treatment device for bio-organic fertilizer fermentation is proposed. In the device, a baffle is provided at a position between the air inlet pipe and the first air outlet pipe in the air storage tank. The baffle is vertically arranged to prevent the waste gas in the air storage tank from being directly discharged from the first air outlet pipe, so that solid particles in the waste gas in the air storage tank can fall under the action of gravity and be separated from the waste gas.

[0004] However, there may be some shortcomings in this patent. In this device, the waste gas is absorbed into the interior of the gas storage tank, and the solid particles in the waste gas fall under the action of gravity and fall into the bottom of the inner wall of the gas storage tank, so that the solid particles are separated from the waste gas. However, there may be some shortcomings in the process. In the long-term treatment of the waste gas, due to the excessive amount of solid particles, the solid particles are easily accumulated at the bottom of the inner wall of the gas storage tank, resulting in the inability of the waste gas to be discharged through the first outlet pipe, thereby affecting the treatment effect of the waste gas. For this reason, we propose a waste gas treatment device for biological organic fertilizer. Utility Model Content
