Problems solved by technology

However, this method still has disadvantages: firstly, adding a stirring device in the biogas tank increases the cost, consumes electricity and is prone to mechanical failure; secondly, the fluidity of the fermentation material is poor, and it is not easy to discharge

Embodiment

[0008] Choose a volume of 1m 3 , a height of 127cm, a biogas fermentation tank with a bottom diameter of 100cm, add 0.15m of straw to the large tank according to the volume ratio 3 , inoculum 0.3m 3 , water 0.4m 3 , mix all ingredients evenly and start fermentation. At normal temperature, the air output rate of the pool volume is 0.3-0.8 cubic meters per day, and under medium temperature conditions, the air output rate of the pool volume is 0.5-1.2 cubic meters per day. Compared with the traditional mixing method, the air output rate has been greatly improved.

Abstract

The invention relates to an ultra-thin evenly mixed straw biogas material distribution mode. By adopting the mode, an anaerobe is promoted to be dispersed in all fermentation liquor, biogas fermentation is facilitated, and the gas efficiency is greatly improved in comparison with the traditional mixing mode. The upper layer of the fermentation liquor is not easily crusted, and is easy to vent, and meanwhile, the ultra-thin evenly mixed straw biogas material distribution mode is simple, convenient and fast to discharge. The ultra-thin evenly mixed straw biogas material distribution mode has the characteristics that the cost is saved, and an energy source is saved.

Description

technical field [0001] The invention relates to a novel straw biogas distribution method, in particular to a distribution method in which an inoculum and an extra-dilute straw are mixed, and belongs to the field of biogas fermentation. Background technique [0002] Biogas is a combustible mixed gas produced by the collaborative fermentation of various microorganisms under anaerobic conditions. Common organic substances include crop straw, weeds, human and animal manure, organic waste, domestic sewage and industrial organic wastewater. These organic substances are fermented by biogas. First, waste that cannot be directly used as fuel (such as human and animal manure) can be converted into clean energy with high taste and high calorific value; second, the thermal efficiency is about double that of direct combustion (such as straw) More than half of the energy can be saved. Therefore, the development of biogas has the dual functions of increasing revenue and reducing expendit...
