Wet type electrostatic precipitator

Abstract

The invention discloses a wet type electrostatic precipitator. A shell is internally divided into an air inlet chamber, an electrode chamber and an air outlet chamber, wherein the air inlet chamber is internally provided with a water spray pipe head which is provided with a nozzle; the electrode chamber is internally provided with a dust collection pipe, and an electrode pipe passes through the interior of the dust collection pipe; a support frame is hung at the upper end of the electrode pipe; the outer end of the support frame and an electrical insulating tube chamber are supported with by an electrical insulator; the outer end of the support frame is connected with a high voltage end negative pole of a transformer / rectifier; a low voltage end external power supply shell of the transformer / rectifier is connected with a power supply shell to be in ground connection; and the cleaning water spray is controlled by the electric field change in the electrode chamber. The wet type electrostatic precipitator has the PM 2.5 removal rate being more than 99%, and has the capability of effectively removing multiple pollutants such as acid mist, various heavy metals and aerosol, thus being widely applied to waste gas treatment in the petro-chemical, chemical industry, pharmacy, war industry and incineration industry.

Description

technical field [0001] The invention relates to a wet electrostatic precipitator for gas purification treatment. Background technique [0002] "PM2.5" in the air quality index is an ultrafine particle with a particle size equal to or less than 2.5 microns, which can be further inhaled into the alveoli, enter the cardiovascular system, and even induce cancer, seriously endangering health. This kind of fine solid and liquid particles is also the "culprit" of haze weather. [0003] The composition of PM2.5 is very complex, including solid particles (fine dust), condensable liquid compound particles, aerosols and heavy metal vapors. Due to the wide sources and complex components of PM2.5, the treatment technology is difficult and the removal methods are various. For the reduction of PM2.5 in industrial waste (combustion) gas, targeted "dust removal" measures should be taken according to the characteristics of PM2.5 in waste (combustion) gas. The most effective device for ...

AI Technical Summary

Problems solved by technology

[0010] 1) The distribution of the airflow among the electrodes is uneven, and there are even "dead angles", which reduces the dust collection efficiency

[0011] 2) The corona intensity of traditional plate electrodes, wire electrodes, and rod electrodes is not high enough, and it is necessary to increase the voltage to obtain high dust collection rate and prevent arc extinguishing effects

[0012] 3) The traditional circular electrode tube has the problem that it is difficult to maintain the concentricity accurately, which makes the electric field uneven, easily causes frequent electric sparks, and affects the overall dust collection effect

[0013] 4) The purified gas and the flushing wastewater are discharged from the same outlet in the same direction, which may easily cause the purified gas to carry dirty wastewater, which seriously reduces the purification efficiency
