Abstract

The invention relates to the field of carbon dioxide adsorption and capture reaction, in particular to a blowing and sucking type carbon dioxide adsorption and capture reaction device, and aims to solve the problems that existing carbon capture equipment is complex in structure and low in efficiency and does not meet development requirements. The air distribution fluidizing device is arranged at the bottom of the flue gas circulation flue, the fluidizing air conveying system is communicated with the air distribution fluidizing device, the middle partition wall is arranged on the inner side of the flue gas circulation flue, and the flue gas circulation flue is divided into a flue gas inlet cavity and a flue gas outlet cavity by the middle partition wall; the high-temperature flue gas inlet flue is communicated with a flue gas inlet cavity internally provided with a front flue heat exchanger, the high-temperature flue gas outlet flue is communicated with a flue gas outlet cavity internally provided with a rear flue heat exchanger, and the carbon dioxide adsorbent supplementing pipeline is arranged on the side portion of the lower end of the flue gas outlet cavity. By using the adsorbent as a carbon dioxide adsorbent, the system arrangement is simplified, and the investment cost and the operation cost are reduced.

Description

technical field [0001] The invention relates to the field of carbon dioxide adsorption and capture reaction, in particular to a blow-suction type carbon dioxide adsorption and capture reaction device. Background technique [0002] The carbon dioxide produced in the production process of thermal power plants, cement, papermaking, industrial boilers and kilns accounts for a large proportion of the total carbon dioxide emissions in my country. The carbon capture has a profound impact on the realization of the dual carbon goal in my country. The existing carbon capture equipment has a complex structure and low efficiency, which does not meet the development needs. SUMMARY OF THE INVENTION [0003] The purpose of the patent of the present invention: In order to solve the problems of complex structure and low efficiency of the existing carbon capture equipment, the present invention proposes a blow-suction type carbon dioxide adsorption and capture reaction device. [0004] The ...
