A high-efficiency temperature swing reactor for a low-temperature carbon capture system

Abstract

The application provides a high-efficiency temperature rising and falling reactor for a low-temperature carbon capture system, which can efficiently realize temperature rising and falling and uniform heat distribution, and comprises an inner reactor body, an outer shell and a sandwich cavity between the inner reactor body and the outer shell; the inner reactor body comprises a flue gas inlet, an adsorption cavity and a flue gas outlet connected in sequence, and the adsorption cavity is used for filling adsorbents; the inner side wall of the inner reactor body is provided with a heat exchange element, the inlet of the heat exchange element is selectively connected with a cold source or a heat source; the outer side wall of the inner reactor body is provided with a heating element; the sandwich cavity is used for introducing cold air; during an adsorption reaction, flue gas enters the adsorption cavity and reacts with the adsorbents, the inlet of the heat exchange element is connected with the cold source, and cold air is introduced into the sandwich cavity to remove the adsorption heat generated in the adsorption reaction; during a desorption reaction, the introduction of flue gas is stopped, the inlet of the heat exchange element is connected with the heat source, and the heating element is started to heat the adsorbents for desorption.
