Description

Composite demister for absorption tower

Technical Field

The utility model belongs to waste gas and waste water clarification plant field especially relates to a compound defroster of absorption tower.

Background

Absorption towers or spray towers are often used in the field of waste gas purification, and liquid mist is sprayed in the towers to increase the purification effect of adsorption packing. To avoid the liquid being discharged with the exhaust gas, it is usually necessary to recover, i.e. demist, the spray liquid. The demister is used as one of the components of the countercurrent absorption tower, the design and the selection of the demister play an important role in the stable operation of the absorption tower, the flue gas treated by the absorption tower carries a large amount of slurry fog drops, particularly, the flow rate of the flue gas of the absorption tower is continuously improved, the amount of the flue gas carrying liquid drops is increased, if the liquid drops are not removed, the liquid drops can be deposited on the surface of equipment at the downstream of the absorption tower to form gypsum scale, the corrosion of the equipment is accelerated, and if the liquid drops are directly discharged outwards, the environmental pollution can be caused. How to design a corrosion-resistant, wear-resistant, easy-to-maintain and high-efficiency demister suitable for an absorption tower is a technical problem to be solved urgently at present.
