Abstract

The inventionrelates to the technical field ofsmoke purification and in particular relates to a device for deep purification of wet desulphurization absorption towersmoke. The device comprises an absorption tower, wherein a slurry tank is arranged at the bottom of theabsorption tower; a smoke outlet is formed in the top of the side wall of theabsorption tower; a smoke inlet is formed in the side wall, higher than the liquid level of the slurry tank, of the absorption tower; a spraying layer and a supporting plate are arranged from bottom to up in sequencebetween the smoke inlet and the smoke outletabsorption tower; and themaximum number of deep purifiers are arranged on the support plate.Kinetic energy of the smoke in the absorption towercan be utilized; gas-liquidimpact isgenerated at blades of rotational flow plates andwalls of rotational flowcylinders when the smoke passes through the rotational flow plates of thepurifiers so thattiny particulate matters such asthin liquid drops, tiny dust particles and aerosol in the smoke impact,aggregate andagglomerate with one another to form large liquid drops; the large liquid drops are captured by surface liquid films of therotational flowcylinders, thusremovingthe tiny particulate matters and reachingthe aim of deep purification of the smoke.

Description

technical field

[0001] The invention relates to the technical field of flue gas purification, in particular to a device for deep purification of flue gas in a wet desulfurization absorption tower. Background technique

[0002] At present, there are many domestic flue gas or industrial tail gas pollution control technologies, among which the relatively mature and representative technologies are: treatment of sulfur dioxide (SO 2 ) polluted limestone-gypsum method, ammonia method, double-alkali method and other wet desulfurization technologies, after spraying, washing and purification of wet desulfurization technology, it is necessary to install a demister to remove tiny droplets generated during the spraying process; as far as the actual Whether it is a flat-plate mist eliminator or a roof-type mist eliminator, the sulfate, sulfite, nitrate, nitrite, etc. The removal efficiency of tiny particles is difficult to meet the environmental protection requirements. In order to mee...
