Abstract

The invention relates to a north methane anaerobic fermentation combined heating system and belongs to methane fermentation equipment. The combined heating system consists of a methane fermentation solar energy heating system and a wind power generation heating system, wherein the methane fermentation wind power generation heating system comprises a wind power generator, a storage battery, an inverter and an electric heater which are communicated by a conducting wire in sequence respectively; both ends of a water outlet pipe of the electric heater are connected to a water outlet of the electric heater and a water inlet of a water tank respectively; and both ends of a water return pipe of the electric heater are connected to a water outlet of the water tank and a water inlet of the electric heater respectively. The system combines two renewable energy resources of solar energy and wind power generation energy to carry out constant energy supply to methane fermentation devices and has the characteristics of simple structure, convenient operation, good operation quality, reliable use and few faults. The system is particularly suitable for assembling and using the methane fermentation devices in alpine areas and has strong adaption capability.

Description

technical field [0001] The invention belongs to biogas fermentation equipment, and mainly relates to a combined heating system of solar energy, wind power and electric energy for biogas fermentation. Background technique [0002] In today's society, energy and environmental protection have become two prominent issues. In the case of decreasing non-renewable energy sources, people began to seek to maximize the use of biomass resources to supplement the energy shortage, and to eliminate the impact on the environment while utilizing biomass resources. pollution. Biogas anaerobic fermentation is a technology that can turn waste into energy and perform harmless treatment, and biogas anaerobic fermentation requires a certain temperature, so it is necessary to carry out biogas anaerobic fermentation system in the process of biogas anaerobic fermentation Heating to maintain a high gas production rate. However, the heat energy of the current biogas anaerobic fermentation heating sy...
