The invention relates to an absorption tower, specifically to a wet flue gas desulfurization absorber tower capable of improving an atomization effect. The wet flue gas desulfurization absorber tower comprises, from top to bottom, a demister, a spraying layer and a slurry tank, wherein a flue gas inlet is arranged between the slurry tank and the spraying layer, a flue gas outlet is arranged above the demister, the demister is connected with a process water conveying pipeline, an atomization nozzle is arranged between the spraying layer and the demister and connected with a water supply pipeline, and the atomization nozzle is a sector nozzle with a jet angle of 60 DEG C. With the wet flue gas desulfurization absorber tower provided by the invention, evaporated water in the absorber tower can be effectively reduced, and a good atomization effect can be obtained.
Description
technical field [0001] The invention relates to an absorption tower, in particular to a wet flue gas desulfurization absorption tower for improving the atomization effect. Background technique [0002] The flue gas emitted by industrial production such as boilers and cement kilns contains a large amount of SO 2 At present, the absorption method of wet flue gas desulfurization and denitrification generally adopts flue gas entering from the bottom of the spray layer in the absorption tower, and countercurrently contacting with the evenly sprayed absorption slurry to remove sulfur dioxide in the boiler flue gas. After washing, the sulfur dioxide in the flue gas is removed, and at the same time, the flue gas also carries a large number of small water droplets. If the flue gas is directly discharged into the air, a large amount of water in the flue gas will be lost, and it will cause damage to downstream equipment. severe corrosion. In addition to installing a mist eliminator i...
