CO2-trapping spray device and technology

Abstract

The invention discloses a CO2-trapping spray device and a technology. The device comprises a spray tower. The top of a tower body is provided with a liquid inlet and a gas discharging port, and the bottom is provided with a liquid discharging port and a gas inlet. A gas distributor is installed above the gas inlet. The liquid inlet is connected with a nozzle device. The nozzle device is formed byorderly distributing nozzle units. Each nozzle unit is formed by a double-layer nozzle plate, a rotation driving component and a pressure sensor. The double-layer nozzle plate comprises a nozzle frontplate and a nozzle rear plate. The nozzle front plate and the nozzle rear plate are uniformly provided with nozzle holes. The rotation driving component comprises a spin core and a rotating ring. Thespin core is provided with an electro-magnetic induction device. The pressure sensor is capable of, through the electro-magnetic induction device, transmitting a signal of a liquid pressure size to the spin core so as to rotate the spin core and drive the nozzle rear plate to be correspondingly rotated, and enabling the nozzle holes of the nozzle front plate and the nozzle rear plate to form dynamic overlapping and interlacing.

Description

technical field [0001] The invention relates to a method for capturing CO 2 The spray device and process, specifically related to a CO capture 2 The invention discloses a spray device with variable liquid flow in a spray tower, belonging to the field of chemical equipment machinery. Background technique [0002] Carbon dioxide capture is increasing in importance in hopes of slowing global warming. Among the various technologies for post-combustion CO2 capture, the use of amines or ammonia (NH 3 ) in an aqueous solution is considered to be the closest to practical use because of the advantages of this method, including high capture efficiency η and high throughput. Chemical absorption using liquid absorbents is usually achieved in packed towers or spray towers, which are the simplest chemical absorption reactors, in which an adsorbent solution is sprayed into an ascending air stream, absorbing carbon dioxide and falling in the opposite direction of the air stream. The siz...
