Problems solved by technology

The existing aerosol particle capture methods include swirling flow separator and electric trap. The pressure drop of the former is generally 500-600Pa, even as high as 1000Pa or more. The existing technology cannot be used for flue gas carbon dioxide capture. In the collection system, first, the pressure drop is too high, and the flue gas with low partial pressure cannot sup...

Abstract

The invention relates to a micro-cyclone liquid collecting method and device for regeneration gas of a flue gas and carbon dioxide capture system. The method comprises the following steps: (a) carrying out air cooling and water cooling on the regeneration gas from a regenerating column so as to convert the serotonin solution-containing saturated steam carried in the regeneration gas into fog drops, thus obtaining regeneration gas carrying aerosol particles; (b) performing gas-liquid micro-cyclone separation on the regeneration gas carrying aerosol particles so as to capture the aerosol particles carried in the regeneration gas so as to obtain aerosol particle-removed regeneration gas; and (c) collecting the captured aerosol particles into a liquid, and directly returning the liquid to the serotonin solution system together with the serotonin solution output from the bottom of a regenerating tower.

Description

technical field [0001] The invention belongs to the field of energy and environment, and relates to a micro-swirl liquid collection method for regeneration gas of a flue gas carbon dioxide capture system, in particular, to a method for liquefying and adding saturated steam containing compound amine solution entrained in the regeneration gas The method of removal, and the apparatus used to carry out the method. Background technique [0002] With the development of economy and society, the air pollution and greenhouse effect caused by the burning of fossil fuels have seriously threatened the earth environment on which human beings depend. Global warming and greenhouse effect are the common challenges facing the sustainable development of all countries. [0003] According to the report of IPCC (The Intergovernmental Panel on Climate Change) (United Nations Intergovernmental Panel on Climate Change), the CO that causes global warming 2 、CH 4 , N 2 O, Hydrofluorocarbon 4 types...
