Abstract

The invention relates to a synergic bypassing and electrocoagulation device for trapping fine particulate matters and heavy metals, the device comprises a shell (1), baffling dust collector plates (2), positive corona electrodes (3), negative corona electrodes (4) and tabulator bars (5); the plurality of baffling dust collector plates (2) are arranged in the shell (1), a flue gas channel in the shell (1) is separated into multiple shunt channels, the positive corona electrodes (3) and the negative corona electrodes (4) are respectively arranged in adjacent shunt channels to charge particles respectively passing through the adjacent shunt channels with different charges, and the multiple tabulator bars (5) are dispersed in the shunt channels. Compared with the prior art, the synergic bypassing and electrocoagulation device can achieve synchronous deep capture of the fine particulate matters and the heavy metals by means of a spoiler and an electrocoagulation by combined with a subsequent high-efficiency dust collector.

Description

technical field [0001] The invention belongs to the non-ferrous metal smelting flue gas fine particle and heavy metal discharge control technology in the field of environmental protection, and in particular relates to a device and method for bypassing flow and electrocoagulation and coordinating fine particle and heavy metal capture. Background technique [0002] The output of non-ferrous metals in my country has ranked first in the world for many years, making important contributions to the national economy. However, the industrial flue gas and environmental flue gas collected in the non-ferrous metal smelting process will contain a large amount of dust and heavy metals, which will cause great harm to human health and the environment. At present, the direction of my country's air pollution control has changed from the electric power industry to the non-electric power industry. The Ministry of Environmental Protection has issued emission standards with special limits for th...
