Description

technical field

[0001] The invention relates to the technical field of straw fermentation, in particular to a straw fermentation biogas device. Background technique

[0002] Straw refers to the remaining stems and leaves after mature threshing of gramineous crops such as rice, wheat, and corn. Due to the popularization of coal, electricity, and natural gas, and the abundance of various industrial products, the demand for straw in rural areas has decreased, and the processing of a large amount of straw has become a As a serious social problem, the way of straw fermentation to produce biogas has been more and more widely used as a way of effective utilization of straw.

[0003] However, the existing fermentation device is to add the crushed straw to the biogas tank for fermentation. The crushed straw is easy to generate dust outside, and the dust pollutes the external environment during the transfer process of the crushed dust. On the other hand, the straw is in the fermentati...
