Solar greenhouse type multi-material biogas, heat and power cogeneration system

Abstract

The invention relates to a solar greenhouse type multiple material biogas and cogeneration system. The solar greenhouse type multiple material biogas and cogeneration system is composed by connection among a straw pretreatment pool, a blending pool, a fermentation pool a solid-liquid separation pool, a first biogas residue storage pool, a second biogas residue storage pool, a water replenishing pool, an air storage tank, a generator set, an air source heat pump and a heating radiator, biogas fermentation, biogas power generation and thermal energy generated from biogas power generation are integrated into a complete system, utilization rate of fermentation substrate degradation can be increased, fermentation system temperature is guaranteed, and waste heat can be used gradually; the complete system is efficient, energy saving, high in adaptability, simple in structure, capable of generating good economic benefits and environment protection benefits and quite good in practical value and significance in popularization.

Description

technical field [0001] The invention relates to the technical field of biogas fermentation, in particular to a solar greenhouse type multi-material biogas and cogeneration system of heat and power. Background technique [0002] Energy shortage, environmental pollution and the resulting human health problems are the main problems faced by today's society, which forces people to research and develop renewable clean energy to solve these problems. Biogas fermentation has the dual benefits of obtaining clean energy and purifying the environment, so it has attracted much attention. my country is a large agricultural country, with an annual output of about 600 million tons of agricultural waste straw, and the number of large-scale farms is increasing day by day in today's society. Diseased and dead livestock and poultry and livestock manure have become a serious environmental pollution and difficult to deal with. Therefore, resources are abundant It is a reasonable and efficient w...

AI Technical Summary

Problems solved by technology

However, most of the current biogas fermentation systems have problems such as low substrate degradation rate and biogas yield, unstable fermentation system temperature, serious heat loss, low energy utilization rate, and unsuitable for industrial continuous production, which seriously restricts the new energy of straw biogas fermentation. technological development
