Technical field
The utility model relates to the Environmental-protecting dust-removing field, relates in particular to a kind of efficient wet electrostatic precipitator.
Background technology
At present in metallurgy, chemical industry, papermaking, the field such as bleaching and dyeing, in, arcola generally adopts electrostatic precipitator to purify the waste gas of discharge.Because the limitation that dry electrostatic cleaner is collected fine dust, a large amount of PM10, PM2.5 dust can't capture.Yet the PM2.5 dust is again the major pollutants that cause haze weather.Therefore, be badly in need of a kind of equipment that can effectively collect the PM2.5 dust.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, efficiency of dust collection is high, safeguard simply and easily efficient wet electrostatic precipitator.
For achieving the above object, the utility model is by the following technical solutions:
A kind of efficient wet electrostatic precipitator, it comprises housing, the top of housing is provided with escape pipe, the sidewall below of housing is provided with air inlet pipe, described deduster also comprises sedimentation basin, discharge electrode, dust collecting pole plate, cathode insulation system, described sedimentation basin is arranged on the below of housing, and the bottom of described housing is provided with ash bucket, and the port of export of ash bucket is communicated with sedimentation basin; Described discharge electrode and dust collecting pole plate are arranged on enclosure interior in opposite directions, and are positioned at the top of air inlet pipe; Described cathode insulation system is arranged on the side top of hull outside, and the cathode insulation system is electrically connected with discharge electrode; Described enclosure interior is provided with spray system, and this spray system is positioned at the top of dust collecting pole plate.
Described deduster also comprises water circulation system, and the water inlet end of this water circulation system is communicated with sedimentation basin, and the water side is communicated with spray system, can recycle water in the sedimentation basin by water circulation system, saves cost.
The water inlet end of described water circulation system is provided with filter, and the water in the sedimentation basin becomes again shower water after filtering, continues to recycle, and can not cause secondary pollution.
Be provided with current equalizer in the described air inlet pipe, by current equalizer, the flue gas that enters enclosure interior is more even, stable.
The outer surface of described cathode insulation system is provided with heater, can avoid like this cathode insulation system outer surface dewfall, causes creepage phenomenon.
Described heater is heating tube, and heating-pipe structure is simple, and cost is low.
