Abstract

The invention discloses an ash water circulation treatment system of a wet electric precipitator. The ash water circulation treatment system comprises an ash water tank for collecting ash water, a spraying device for removing dust, a circulating water system and a process water system, wherein ion exchange equipment is further connected between a sedimentation basin and the spraying device. The ash water circulation treatment system has the following advantages and effects: alkali liquor and a coagulant are respectively added into a circulating water pool and a process water pool, so that slightly soluble matters in water are changed into soluble sodium salt, suspended solids coagulate and settle down, and the content of the suspended solids is reduced; moreover, the PH value of the water is controlled to be 7 or less, the water is in a near-neutral and slightly acidic state, and corrosion to metal can be reduced.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to a gray water circulation treatment system of a wet electric dust collector. Background technique [0002] Wet electrostatic precipitator is a kind of dust removal equipment used to deal with trace dust and fine particles. It is mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM2.5 and other harmful substances in wet gas. It is Ideal equipment for controlling air dust pollution. [0003] The authorized announcement number is CN103056031B, and the authorized announcement date is August 24, 2016. The Chinese patent discloses a gray water circulation treatment system for a wet electrostatic precipitator, including: a gray water tank for collecting gray water discharged from the wet electrostatic precipitator; The supply branch includes the supply water tank and the flushing water pump; the water inlet of the flushing water pump is connected to the supply wa...
