Distributed energy comprehensive utilization system for biomass energy and solar energy

Abstract

The invention relates to a distributed energy comprehensive utilization system for biomass energy and solar energy, which comprises a biomass gasifying device, a methane generating device, a solar thermal collector, a solar photovoltaic generating device and a gas-steam combined cycle generating device, wherein biomass gas is supplied to a gas turbine set for generating power, exhaust gas of the gas turbine is supplied to an exhaust-heat boiler, major steam of the exhaust-heat boiler is supplied to a steam turbine set for generating power, and exhaust gas of the exhaust-heat boiler is used asa main heat source of the methane generating device; the solar thermal collector supplies hot water serving as a heating heat source and a standby heat source of the methane generating device, the hot water of the solar thermal collector is converted into high-temperature heating medium water through an auxiliary heater to drive a refrigerator to refrigerate, a heat source of the auxiliary heateris from part of high-temperature exhaust gases of the gas turbine, and the exhaust of the gas turbine is used as an additional heat source of the methane generating device; methane is used for cooking; and the solar photovoltaic generating device provides electric energy for communal facilities. The distributed energy comprehensive utilization system realizes the cascade utilization of the energymeeting multiple requirements of users directly, and relieves environmental pollution caused by energy consumption of eco-villages.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of energy, in particular to a comprehensive utilization system of biomass energy and solar energy distributed energy in the construction of ecological villages. Background technique [0002] At present, the application range of biomass energy and solar energy in rural areas is getting wider and wider, but the utilization method is still relatively simple. For example, the biomass utilization method is to produce biogas through fermentation. Due to the small-scale decentralized mode adopted, the biogas production is low, the controllability is poor, and it cannot be reasonably allocated and fully utilized. waste; and because the fermentation process of biogas is greatly affected by temperature, especially in winter when the temperature is low, resulting in a decline in biogas production, it is difficult to meet the needs of normal life. Solar collectors are greatly affected by the weather,...
