Embodiment Construction

[0025] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the case of no conflict, the embodiments and the features in the embodiments of the present invention can be combined with each other. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, the present invention can be modified or changed, but these modifications or changes also fall within the protection scope of the claims of the present invention.

[0026] The main reaction principle: in the absorption tower, alkali metal-based solid absorbent and CO 2 The reaction process belongs to the reaction of gas and porous solid. In the presence of water vapor, the alkali metal-based solid absorbent absorbs CO 2 Generate alkali metal-based acid carbonate; in the regeneration tower, alkali metal-based acid carbonate absorbs heat and desorbs to generate CO 2 Mixed gas with water vap...

Abstract

The global warming problem caused by greenhouse gas emission is one of the focus points generally concerned by the international society nowadays, the ratio of CO2 in the greenhouse gas is as high as 60%, and under previous research and demonstration, it is believed that the alkali metal-based solid absorbent for flue gas decarburization has a wide application prospect. The invention aims to provide an automatic-regulation continuous multi-bed decarburization system applying an alkali metal-based solid absorbent, which comprises at least one absorption unit, a regeneration unit, a control unit, a waste heat recovery device and a CO2 purification unit, and in addition, according to the requirements of trapping efficiency, energy consumption and the like, the continuous multi-bed decarburization system applying the alkali metal-based solid absorbent can be automatically regulated. A two-stage or three-stage combined decarburization system can be arranged. The whole system has the advantages of high selectivity of CO2 absorption and environmental friendliness, and has great popularization value.

Description

technical field [0001] The invention belongs to the field of flue gas carbon emission reduction, and in particular relates to an automatically adjusted continuous multi-bed decarbonization system. Background technique [0002] The problem of global warming caused by greenhouse gas emissions is one of the focuses of the international community today. Among greenhouse gases, CO 2 Accounted for up to 60%, CO 2 The most important source is the burning of fossil fuels, 3 / 4 of CO 2 Produced by combustion, especially coal-fired power plants emit a large amount of CO 2 gas. At present, carbon capture technology is still in the stage of R&D and demonstration. The main problem is that the investment and operation costs are too high. 2 There is still a lack of effective means to capture and store large quantities of CO2 2 Capture and storage technology has become a key technology to control global warming and has attracted more and more attention at home and abroad. [0003] CO ...
