System for generating sewage gas by straw

Abstract

The invention provides a system for generating sewage gas by a straw, belongs to the technical field of sewage gas, and solves the technical problems that the existing sewage gas production system is complicated in structure, low in biogas production efficiency, low in automatic degree and the like. The system for generating the sewage gas by the straw comprises a straw crusher, a methane tank, and a delivery device which is arranged between the straw crusher and the methane tank; a rotating mechanism capable of driving a moving cutter cylinder and making a moving blade tangent with a fixed blade is arranged on the straw crusher; the delivery comprises a transport cylinder, a delivery pipe and a fan; the methane tank comprises a tank body, a tank cover, a connecting pipe 1 and an air storage tank; the methane tank is provided with a control mechanism 1 and a control mechanism 2; the first control mechanism 1 can stabilize the pressure of the methane tank; and the control mechanism 2 can adjust the temperature of the methane tank. The system disclosed by the invention has the advantages of simple structure, high gas production efficiency, security, stability, and high automatic degree; and the energy source can be saved.

Description

technical field [0001] The invention belongs to the technical field of biogas, and relates to a production system, in particular to a system for producing biogas by utilizing straw. Background technique [0002] With the development of the economy, energy has become an important guarantee for the sustainable development of the economy. At present, people's excessive use of non-renewable resources has made all countries face a severe test of energy issues. Biogas is a kind of clean energy in rural areas of our country. It is produced by fermenting the waste straw of crops. It can be used for boiling water and cooking, etc. It can save a lot of natural resources such as coal and wood for human beings, and the burned Biogas will not pollute the environment and has high thermal efficiency. [0003] At present, the biogas production of biogas digesters is usually subject to certain restrictions, for example, it will affect the biogas production with seasonal and diurnal tempera...
