Photovoltaic photo-thermal coupling co-electrolysis combined garbage power generation comprehensive energy system and process method thereof

The invention provides a photovoltaic photo-thermal coupling co-electrolysis combined garbage power generation comprehensive energy system and a process method thereof. The system comprises an amino thermochemical heat pump system, a linear Fresnel heat collection system, an SOEC electrolysis system, a PSA nitrogen generation system, an ammonia synthesis module, a methanol synthesis module and a garbage power generation module. Solar photovoltaic and photo-thermal are combined with an amino thermochemical heat pump system to provide electricity and heat for an SOEC electrolysis system, solar power generation is used for driving air to be separated into nitrogen and oxygen and driving water to be electrolyzed into hydrogen and oxygen, oxygen serves as a combustion improver for waste incineration power generation, and waste incineration power generation outputs electric energy. The generated high-temperature CO2 can be directly mixed with water vapor and is introduced into an SOEC electrolytic tank for co-elect
