Gas absorption purifier

Abstract

The invention relates to a gas purifying device, which is a vertical drum-type equipment, on the top thereof are arrange a gas collection chamber and a gas outlet, and a liquid collection chamber and a liquid outlet are arranged on the bottom of the gas purifying device, a main chamber is provided between the gas collection chamber and the liquid collection chamber, on the upper part of the main chamber is arranged a mist eliminator, a gas tangential inlet is arranged on the lower part of the main chamber near to the liquid chamber, and an absorption liquid inlet is provided below the mist eliminator. In the main chamber, a group of fluid directors are coaxially arranged in a certain space. The leakage between the fluid directors and the tower inner wall can be reduced maximally via the outer rings on the fluid directors. After the gas to be treated enters the tower via the gas inlet, it rotates and runs up simultaneously. The absorption liquid injected via the liquid inlet has a contact with the rising rotary gas flow, and the absorption liquid can form liquid film, liquid silk, and liquid drop to under turbulent shearing action of swirling flow field, which makes gas and liquid have a sufficient contact; and because of the fast gas-liquid relative velocity and great turbulent degree, the invention is provided with high gas-liquid mass transfer rate and good absorption effect.

Description

technical field [0001] The invention relates to gas purification equipment, in particular to a device for strengthening gas absorption and separation using cyclone technology. Background technique [0002] After searching, there is an invention patent 200410074338.8 vortex gas purification and separation device. The cyclone is used to generate a swirl, followed by a separation tube, that is, the swirl tube separates the condensate in the gas. The swirl technology is not used to strengthen the absorption and separation process. [0003] Utility model patent 94230343.1 dust removal and desulfurization device, the flue gas drawn from the chimney passes through the cyclone to form a swirling airflow, and flows in the flue to the absorption liquid atomized by the nozzle to achieve the purpose of absorption and purification. The cyclone here is actually a deflector, which only plays the role of generating swirl. [0004] Utility model patent 98239353.9 Ceramic desulfurization dev...

Problems solved by technology

[0006] Utility model patent 200420005716.2 The atomization swirl desulfurization and dust removal device is a swirl plate tower, the elevation angle of the swirl plate blades is 35-45°, there are only two layers of swirl plates, and there are no leak-proof measures

Existing gas purification devices, such as flue gas desulfurization devices, are bulky, resulting in huge investment. The reason is that the efficiency of the absorption process in the equipment is low, which can only be compensated by increasing the number of stages or increasing the equipment
