Abstract

The invention relates to a combined heat and power generation system based on supercritical CO2 coupling chemical looping combustion and supercritical hydrothermal reaction and a working method. At present, no combined heat and power generation system based on supercritical CO2 coupling chemical looping combustion and supercritical hydrothermal reaction with high energy utilization efficiency of achemical looping combustion system exists. The combined heat and power generation system comprises a chemical looping combustion system, a coal water slurry system and a heat and power generation system, and is characterized by further comprising a supercritical water oxidation system, wherein the supercritical water oxidation system comprises a high-pressure coal water slurry pump, a supercritical hydrothermal reactor, a preheater, a CO2 separator and an N2 tank; the high-pressure coal water slurry pump is connected with the coal water slurry system; the preheater is connected with the supercritical hydrothermal reactor; the supercritical hydrothermal reactor is connected with the high-pressure coal water slurry pump, the CO2 separator and a cyclone separator through pipelines respectively; and the N2 tank is connected with the CO2 separator and the heat and power generation system through pipelines respectively. The chemical looping combustion system is high in energy utilization rate, and oxygen-carrying particles in chemical looping combustion are not easy to sinter.

Description

technical field [0001] The present invention relates to a supercritical CO 2 The utility model relates to a cogeneration system and a working method for coupling chemical chain combustion and supercritical hydrothermal reaction, belonging to the fields of carbon emission reduction and energy technology. Background technique [0002] CO in Earth's atmosphere since industrial civilization 2 Concentrations rise sharply due to human productive activities. CO 2 As a typical greenhouse gas, it directly causes the greenhouse effect. Currently, supercritical CO 2 Power generation is to control CO 2 A novel utilization technology of emissions, which takes CO2 in a supercritical state 2 As the working fluid, the energy of the heat source is converted into mechanical energy. Because supercritical carbon dioxide has the characteristics of high energy density and high heat transfer efficiency, the power generation system with its working fluid can reach the efficiency of 700 ℃ of ...
