Thermodynamic system for complementary heat supply of solar energy and biomass

The invention provides a solar energy and biomass complementary heat supply thermodynamic system. The solar energy and biomass complementary heat supply thermodynamic system comprises a working medium storage device, a heat collector, a deaerator and a biomass boiler. The working medium storer is used for storing and conveying a heat exchange working medium. The heat collector is used for collecting solar heating heat exchange working media, and a working medium outlet of the working medium storage device communicates with a working medium inlet of the heat collector. A working medium outlet of the heat collector is communicated with a first working medium inlet of the deaerator and/or a steam inlet of the deaerator, and a working medium outlet of the working medium storage device is communicated with a second working medium inlet of the deaerator. A working medium outlet of the deaerator communicates with a working medium inlet of the biomass boiler, and a steam outlet of the biomass boiler communicates with
