Description

Technical Field

[0001] The utility model relates to the technical field of biogas engineering, in particular to a homogenizing stirring tank for biogas engineering. Background Art

[0002] In biogas production, various organic wastes, such as straw, livestock and poultry manure, food waste, restaurant kitchen waste, municipal sludge, industrial fat, brewing waste, slaughterhouse waste, and agricultural waste, are homogenized, stirred, and mixed in a mixing tank before being fed into an airtight fermentation tank. Anaerobic fermentation produces biogas and digestate. Homogenizing and mixing tanks used in biogas projects are specially designed to process organic waste and promote the biogas fermentation process. These tanks utilize an internal agitator to thoroughly mix the fermentation materials, optimizing the growth environment for microorganisms during the fermentation process, thereby increasing biogas production and quality. They are typically constructed of corrosion-resistant materials.

[0003] The homogenizing stirring tank and the fermentation system having the homogenizing stirring tank disclosed in the Chinese utility model patent application publication specification CN208378863U can crush the raw materials into smaller pieces, so that the mixed materials entering the fermentation tank can produce biogas faster and produce more biogas. However, the homogenizing stirring tank has low flexibility in use and cannot quickly adjust the stirring speed according to the actual fermentation situation of the organic waste, thereby affecting the overall mixing effect and mixing quality of the organic waste.
