Abstract

The invention relates to a high-efficient demisting device in a wet desulfurization tower, belongs to the technical field of demisters, and aims at solving the problems that an existing demisting device in a wet desulfurization tower is poor in demisting effect and attachments attached to a demister are hard to wash. The demisting device comprises a desulfurization tower body, an alkaline water mixing plant, a spraying device, a folded-plate demister and a spraying drive device; the alkaline water mixing plant is installed on the outer wall of the desulfurization tower body and provides a water source for the spraying device, the spraying device and the folded-plate demister are arranged in the desulfurization tower body from top to bottom, and the folded-plate demister is rotatably installed in the desulfurization tower body. In the high-efficient demisting device in the wet desulfurization tower, 'mist' produced in an absorption tower during wet desulfurization is processed through the spraying device and the folded-plate demister, the demisting process is accelerated, there is no need to arrange a long buffer path for the smoke, and the occupied area of a wet desulfurization system is reduced.

Description

technical field [0001] The invention relates to a demister device in a high-efficiency wet desulfurization tower, which belongs to the technical field of demisters. Background technique [0002] In wet desulfurization, during the operation of the absorption tower, it is easy to produce "fog" with a particle size of 10-60 microns. "Fog" not only contains water, but also dissolves sulfuric acid, sulfate, sulfur dioxide, etc. , Heat exchangers and flue contamination and severe corrosion, therefore, the wet desulfurization process requires demisting of the absorption equipment, and the purified gas must be demisted before leaving the absorption tower. [0003] The mist eliminators in the prior art have poor demisting effect, and a large amount of mist in the exhaust gas has not been removed. If the mist carrying corrosive substances is not removed, it will cause corrosion of subsequent processing equipment. If the mist is directly discharged to the outside , will cause serious ...
