Description

technical field [0001] The invention relates to a renewable energy comprehensive utilization system, in particular to a biomass energy-methane fermentation-solar energy integrated utilization system. Background technique [0002] We know that there are currently two forms of biomass energy utilization in rural areas in my country. One is fuel preparation based on low-moisture biomass such as straw and combustible garbage, which is mainly used for centralized gas supply or small-scale power generation for residents in rural areas; the other is It uses high-moisture biomass such as feces and perishable garbage to convert hydrocarbon energy into biogas to generate biogas, and it is also mainly used for cooking gas supply for rural residents. However, these two forms of utilization have certain limitations, and cannot completely solve the problems of energy supply and environmental pollution in villages. [0003] The biomass gasification system has the advantages of large gas pr...

Problems solved by technology

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a biomass energy-biogas fermentation-solar energy integrated utilization system, which can not only realize the centralized treatment of human and livestock feces and domestic sewage in villages and towns, turn pollution into biogas resources, but also improve straw gasification , gas purification level, to solve the problems of high tar content, low calorific value and low gasification efficiency in the existing straw gasification; and to use straw gas and solar thermal technology to heat the biogas fermentation system, which solves the problem of biogas gas production in cold seasons The problem of poor stability ensures the organic combination and mutual complementarity of the two biomass utilization technologies and expands the application field of biomass energy
