Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] The energy-saving carbon dioxide capture system of the present invention, such as figure 1 As shown, including the water washing tower 1, the negative pressure of the flue gas enters the water washing tower 1, and the net flue gas washed by the water washing tower 1 is blown into the absorption tower 2 through the positive pressure of the induced draft fan 18;

[0040] The washing tower 1 is mainly composed of the tower body, spraying, packing, inlet and outlet, and liquid outlet. The washing water enters from the top of the washing tower 1, and the washing waste liquid is discharged from the bottom of the washing tower 1 to the sewage treatment. After the washing circulating water is combined with the washing water, the flue gas washing process is continued.

[0041] The flue gas is the clean flue gas after desulfurization. After the...

Abstract

The invention discloses an energy-saving type carbon dioxide trapping system which comprises a washing water treatment loop, a desalted water / regenerated gas condensate water treatment loop, an alkali liquor treatment loop, an alkali liquor treatment loop and a flue gas treatment loop. The invention further discloses a trapping method of the trapping system. The problems that an existing trapping system is large in occupied area and high in energy consumption are solved.

Description

technical field [0001] The invention belongs to the technical field of carbon dioxide capture, and relates to an energy-saving carbon dioxide capture system, and also relates to a capture method of the above-mentioned capture system. Background technique [0002] In recent years, the intensification of the greenhouse effect has posed serious challenges to the sustainable development of the environment and economy. Therefore, the emission reduction technology of carbon dioxide that causes the greenhouse effect and global climate change has become the focus of attention of various countries. Carbon dioxide capture and storage is one of the most promising solutions to address climate change. [0003] Carbon dioxide capture methods mainly include absorption method, adsorption method, membrane separation method, low temperature separation method and so on. [0004] Membrane separation method is to use some polymer materials, such as cellulose acetate, polyimide, polysulfone, et...
