Absorption tower with wet type electric demister

Abstract

The invention discloses an absorption tower with a wet type electric demister. The absorption tower comprises a slurry pool (2), an absorption zone (3) and an absorption tower top part (7), which are communicated in sequence from bottom to up along the flowing direction of smoke, wherein the absorption zone (3) is provided with an absorption tower entrance (1), a spraying layer (4) and a mechanical demister (5) in sequence along the flowing direction of smoke; the wet type electric demister (6) is arranged between the mechanical demister (5) and the absorption tower top part (7); a spraying washing device (9) is arranged right above the wet type electric demister (6) and a washing water collection device (8) is arranged right below the wet type electric demister (6). By additionally arranging the washing water collection device below the wet type electric demister, the technical bottleneck that a wet type electric demister with receiving electrodes cannot be arranged in the upper part of a cooling tower is overcome; the site space is effectively utilized and the occupied area is small; washing water is recycled and thus the water resource is saved.

Description

technical field [0001] The invention relates to the field of flue gas desulfurization, in particular to an absorption tower including a wet electric demister. Background technique [0002] In recent years, countries around the world have paid more and more attention to environmental protection, and environmental protection standards have become increasingly strict. Restricted by emission standards, some developed countries have removed SO emissions from flue gas 2 In addition to taking effective control measures for , NOx and smoke, the emission reduction of fine smoke, mercury and other pollutants in the form of aerosols has been put on the agenda. [0003] So far, my country's emission restrictions on soot-type pollutants are mainly SO 2 and soot. Most coal-fired power plant generating units are equipped with dust removal and desulfurization devices, of which wet desulfurization process accounts for about 90% of all desulfurization devices. [0004] Although the wet de...
