Wet Electrostatic Precipitator
Wet Mist Eliminators
High concentration of acid mist gas, dust-containing sulfur-containing gas, after neutralization, absorption and purification, will produce a large amount of smoke, such as triacid, chromic acid, hydrofluoric acid, sulfur dioxide, etc.
If the air volume and wind speed are large, the situation will be aggravated, and some of the exhaust gas may not be completely neutralized, thus failing to meet the emission standards. At this time, we need to carry out defogging treatment.
Wet electrostatic precipitator is also called wet electrostatic precipitator, wet electrostatic precipitator. It is widely used in industrial production such as acid mist treatment, desulfurization and dust removal, and has a history of application for hundreds of years.
Scope of application:
After acid mist neutralization treatment; smoke removal after wet dust removal and desulfurization device. It is widely used in acid-base, dust- and sulfur-containing waste gas demisting treatment in the process of pickling, electroplating, aluminum, metallurgy, brick factory, power generation, boiler, chemical industry, electronics, machinery manufacturing and other industries.
The main shell is made of stainless steel 316L plate, with built-in cathode rods, anode plate bundles, insulating boxes, and clean water systems; below the main shell is a sedimentation collection chamber: there are observation windows and discharge ports, and a waste water collection tank made of cement, plastic or FRP can be used.
The principle is to send a DC negative high voltage to the electric field space, and through the ionization of the space gas, the dust particles and droplet particles in the flue gas are charged and move to the electrode plate under the action of the electric field force, and the droplets become larger and larger. Gravity flows into the sediment collection chamber.
1. The defogging efficiency is more than 95% higher, and the gas suspended particles and mist diameter are within 0.01–100um
It can be removed, and it has a wide range of applications for smoke and smoke, and the process is mature, safe and reliable;
2. Corrosion resistance, no wear, long service life, and can be used for a long time under the condition that the electrode is well maintained;
3. Small resistance, low energy consumption, low noise, simple and convenient maintenance.
