Absorption tower exhaust gas absorption principle-Zibo Hangtai Industry and Trade

The gas-liquid two-phase flow pattern in the tail gas absorption tower can be countercurrent or cocurrent. Countercurrent operation is usually used. The absorbent is added at the top of the tower and flows from top to bottom. It contacts the gas flowing from bottom to top. The liquid that has absorbed the absorbent is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower.
The basic requirements that an industrial absorption tower should have
The gas and liquid in the tower should have sufficient contact area and contact time.
There is strong disturbance in the gas and liquid phases, which reduces the mass transfer resistance and improves the absorption efficiency.
, wide operating range and stable operation.
The equipment has small resistance and low energy consumption.
, has sufficient mechanical strength and corrosion resistance.
, simple structure, easy to manufacture and repair.
The tail gas absorption tower is a device that implements absorption operations. It is divided into three categories according to the gas-liquid phase contact form.
One is the packed absorption tower and falling film absorption tower where the liquid contacts the gas phase in a film-like motion.
The second is the plate tower, bubble absorption tower, and stirred bubble absorption tower in which gas is dispersed in the form of bubbles in the liquid phase. The third is the ejector and venturi that the liquid is dispersed in the gas phase in the form of droplets. Pipe, spray tower
