DETAILED DESCRIPTION - Comprehensive energy utilization system of distributed biomass and solar energy comprises a biomass gasifying device, a biogas generating device, a solar heat collector and a solar photovoltaic power generation device, where the biomass gasifying device is provided with a gas turbine, a steam turbine, a waste heat boiler and a pull double-shaped gas-steam coupled circulatory generation device constituted by a generator. The gas produced by the biomass gasifying device supplies the gas turbine. The high-temperature waste gas produced by the gas turbine is used as a heat source by the waste gas boiler. The main steam produced by the waste gas boiler supplies the steam turbine. The gas turbine and the steam turbine drive the generator by a speed reducer to supply electricity to the inhabitant. The gas produced by the biomass gasifying device supplies the gas turbine to drive the generator to supply electricity to the inhabitant. The exhausted gas of the waste gas boiler is conveyed to a cylindrical-wall interlayer of the biogas generating device to be used as the primary heating heat source. The solar heat collector supplies hot water to the user as the heat source and a backup heat source of the biogas generating device. The hot water of the solar heat collector is converted by an auxiliary heater into a high-temperature heat medium water as a power driving refrigerator to refrigerate the room. The heat source of the auxiliary heater is from a part of the high-temperature waste gas of the gas turbine. The exhausted gas is conveyed to a cylindrical-wall interlayer of the biogas generating device to be used as the auxiliary heat source. The biogas produced by the biogas generating device is used for cooking by a biogas purification and storage device. The solar photovoltaic power generation device directly supplies the electric energy for public facility.
