Solar Photoelectric Refrigeration Assisted Hydrate Carbon Capture System

Abstract

The invention discloses a solar photoelectric refrigeration assisted hydrate method carbon capture system. The solar power generation device is connected with a thermoelectric refrigeration device and an inverter, and the other end of the inverter is connected with an absorption refrigerator and compressors of various stages; After exchanging heat with the thermoelectric refrigeration device and the absorption refrigerator, it exchanges heat with the coolers and reactors at all levels; the mixed gases such as industrial flue gas CO2 and N2 pass through the absorption refrigerator and the first-stage hydrate method carbon successively. Capture system, second-stage hydrate carbon capture system. The invention realizes the cascade utilization of energy, utilizes solar power to generate electricity, and provides electric energy for thermoelectric refrigeration devices, absorption refrigerators and compressors at all levels to provide a low-temperature and high-pressure environment for hydrate formation; the two-stage separation method of hydrate is used to realize CO2 capture , the process is simple, the raw materials are economical, and the separation efficiency is improved; the industrial flue gas separation is realized by using solar power generation, thermoelectric refrigeration, hydrate CO2 capture and other systems, with little environmental pollution and high energy utilization efficiency.

Description

technical field [0001] The invention relates to a solar energy assisted carbon capture technology, in particular to a system for capturing carbon dioxide by solar photoelectric refrigeration assisted hydrate method. Background technique [0002] Since entering the 21st century, CO 2 Issues such as global warming caused by greenhouse gases are becoming more and more serious. Atmospheric CO 2 The rapid increase in concentration mainly comes from the gases emitted by industrial production, such as exhaust gases from coal-fired boilers, waste incinerators, and steel plants, etc., all contain high concentrations of CO 2 . Therefore, for CO in industrial flue gas 2 Separation and capture has become the focus of greenhouse gas emission reduction. [0003] As an emerging technology, the hydrate CO 2 The capture technology has the characteristics of no corrosion to equipment, no pollution to the environment, and can realize the integration of capture and storage, so it is consi...
