The invention provides a numerical
simulation method of a circulating type
flue gas
decarburization system, and belongs to the technical field of
chemical energy. Based on gridding modeling and division and setting of multiple reaction areas, a
reaction model between gas and
solid phases in circulation is established and solved, by setting an absorption area
assembly and a regeneration area
assembly, the working conditions of a
carbon dioxide absorption area and an absorbent regeneration area are adjusted, and then the gas-
solid reaction form of the
carbon dioxide absorption area and the absorbent regeneration area is adjusted. Therefore, the absorption-removal circulation of
carbon dioxide in the
system is realized. The device comprises an absorption area
assembly and a regeneration area assembly, and further comprises a communicating
pipe assembly, one side of the absorption area assembly is provided with an absorbent particle inlet, the other side of the absorption area assembly is provided with a communicating
pipe assembly, the other end of the communicating
pipe assembly is communicated with a regeneration area assembly, the other side of the regeneration area assembly is provided with a regeneration particle inlet, and the communicating pipe assembly is arranged between the absorption area assembly and the regeneration area assembly.
