High gas speed and high efficiency wet-type electrofiltration device for deep treatment of PM2.5

Abstract

The invention relates to a high gas speed and high efficiency wet-type electrofiltration device for deep treatment of PM2.5, which mainly comprises a main shell and an electrode separation device arranged in the main shell, wherein a lower air chamber is arranged at the lower part of the main shell and an upper air chamber is arranged at the upper part of the main shell; an exhaust inlet and a pollution discharge port are formed in the lower air chamber; a gas distribution device is arranged at the connecting part of the lower air chamber and the main shell; an exhaust port is arranged at the top of the upper air chamber; the electrode separation device comprises a cathode device, an anode device and a power supply device; the anode device is honeycomb-shaped conductive composites tube bundle; the cathode device comprises a cathode connecting board positioned in the upper gas chamber and a plurality of cathode wires hung on the cathode connecting board; cathode wires penetrate the honeycomb-shaped conductive composites tube bundle in one-to-one correspondence; a heavy hammer is connected with the lower end of each wire. The high gas speed and high efficiency wet-type electrofiltration device has good collection effects to tiny / viscous / high resistance ratio PM2.5 particulates, aerosol, tiny metal particles, dioxin and the like.

Description

technical field [0001] The invention relates to the technical field of electric dust removal equipment, in particular to high-gas-velocity and high-efficiency wet electric filter equipment for PM2.5 deep treatment. Background technique [0002] "China is currently one of the areas with the most serious PM2.5 pollution in the world." The PM2.5 index of London, which has the worst air pollution in history, is about 10 to 20 micrograms per cubic meter, while Beijing reached 90 micrograms per cubic meter at its peak. About 50 micrograms per cubic meter in Guangzhou and other cities. PM2.5 fine particles are carriers of viruses, bacteria, and harmful substances. The physiological structure of the human body determines that there is no ability to filter or block PM2.5. After desulfurization and denitrification in petroleum, chemical, electric power, metallurgy, cement, textile, biology, pharmaceutical and other industries, the wet flue gas contains a large amount of fine dust, a...
