Description

Technical Field

[0001] The invention relates to the technical field of environmentally friendly new energy, and more specifically to an assembled flexible material dry fermentation system. Background Art

[0002] my country's rural straw resources are very rich. Currently, there are nearly 20 kinds of important crop straws, and the output is huge. However, the remaining crop straws are abandoned in the fields and yards, which not only occupies a large amount of land, but also affects the rural environmental sanitation. With the increasing amount of agricultural straw, domestic garbage, livestock and poultry manure, etc., the environmental and energy pressures are constantly increasing, and the utilization of biomass resources has become an urgent need. Anaerobic fermentation technology is one of the hot spots and key directions of research at home and abroad.

[0003] At present, biogas plants mainly process livestock manure and mix a small amount of straw as raw materials. Straw can usually produce 250-300 cubic meters / ton of biogas containing more than 50% methane, while even dry cow dung can only produce about 100 cubic meters / ton of biogas, and wet cow dung can only produce 20-30 cubic meters / ton of gas.

[0004] In the biomass fermentation industry, the traditional practice is to build a permanent biogas project by digging the foundation and constructing fixed fermentation equipment. The problem is that the high cost of industrial land construction has pushed up the cost of biogas production. At the same time, large-scale promotion and implementation will inevitably occupy a large amount of agricultural arable land. The collection of straw raw materials, the use radius of product fertilizers and biogas all seriously affect the production cost of biogas. Rural household energy use is seasonal. Winter heating in the north requires a lot of energy, while cooking in other seasons requires less energy. The traditional method of processing agricultural straw is a mixed wet treatment that can be used together with poultry and livestock manure. There are problems such as straw pretreatment, easy crusting, high energy consumption, low energy efficiency, and difficult operation and maintenance. In view of this, we propose an assembled flexible material dry fermentation system. Summary of the invention
