Abstract

The invention relates to an energy-saving type temperature swing adsorption system and method for separating carbon dioxide in industrial flue gas. The system comprises a first adsorption bed, a second adsorption bed and a third adsorption bed, wherein each adsorption bed is provided with a heat exchange chamber and an adsorption chamber which are independent of each other; the system also comprises a hot flue gas supply pipe which is communicated with each adsorption chamber or each heat exchange chamber in a switchable manner, an air supply pipe which is communicated with each heat exchange chamber in the switchable manner, and a CO2 supply and recovery pipe which is communicated with each adsorption chamber in the switchable manner. According to the method, three cyclic states are included, CO2 in the flue gas can be continuously adsorbed and separated, meanwhile, in a temperature swing adsorption process, the heat of the flue gas is used for heating an adsorbent to enable the adsorbent to be desorbed and regenerated, and the temperature of the flue gas in the process is reduced, so that energy consumption for adsorption and desorption is reduced. The system and the method provided by the invention solve the problems of difficult separation of the carbon dioxide in the industrial flue gas, and the high energy consumption of an existing temperature swing adsorption technology, and the aims of energy conservation and carbon dioxide emission reduction are realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an energy-saving temperature swing adsorption system and method for separating carbon dioxide in industrial flue gas. Background technique [0002] In recent years, global warming and a series of related environmental problems have become increasingly prominent, CO 2 It is a major greenhouse gas in the atmosphere, and its global emissions in 2015 reached 32.1 billion tons. CO 2 Mainly from industrial emissions, especially industrial boilers burning fossil fuels emit a large amount of CO into the atmosphere through the flue 2 . CO in industrial flue gas 2 Technologies for separation and capture are in urgent need of further development to reduce greenhouse gas emissions and mitigate global warming. [0003] Currently in the separation of industrial flue gas CO 2 Among the multiple technologies, absorption separation and adsorption separation are ...
