Wet electrostatic precipitator for tail gas desulfurization

Wet electrostatic precipitator for exhaust gas desulfurization has become an important part of exhaust gas treatment. At present, it is in a leading position in the application field of tail gas desulfurization wet electrostatic precipitator equipment such as thermal power plants, smelters, waste incineration plants, coal-fired kilns, etc. The tail gas desulfurization wet electrostatic precipitator solves the problem of flue gas treatment and emission without secondary pollution. , can meet the emission standards.

The contact of the flue gas and water will cause the water to filter the dust and other substances in the flue gas. Using this principle, the wet electrostatic precipitator used for exhaust gas desulfurization can better capture dust particles, so that the dust concentration exceeds 10ml, so as to better remove the dust in the flue gas. The tail gas desulfurization wet electrostatic precipitator is a comprehensive device, including support components, desulfurization components and electrostatic precipitator components.

Wet electrostatic precipitator is a kind of dust removal equipment for tail gas desulfurization. The high-voltage electricity passes through the electrodes to generate a corona discharge, releasing free electrons and ions to charge the dust particles. The charged particles move into the dust collector under the action of the electric field force, and are collected to realize gas-solid separation. The wet electrostatic precipitator used for tail gas desulfurization has the advantages of high dust removal efficiency, low resistance and low energy consumption. Effectively capture dust in flowing, high temperature or corrosive gases.

Wet electrostatic precipitators for tail gas desulfurization can remove more than 85% of fine dust and can effectively remove PM2 5. Waste gas such as SO3, NH3, aerosol, heavy metal plasma, etc., the comprehensive desulfurization efficiency of pollutants is above 80%. Wet electrostatic precipitator is an important equipment for tail gas desulfurization, which plays a very key role in the emission index of high-voltage power supply.

The tail gas desulfurization wet electrostatic precipitator has been used in industrial dust removal for many years. With the improvement of environmental protection requirements, many industrial industries have a certain understanding of tail gas desulfurization wet electrostatic precipitator equipment, and have been more and more widely used. It is an ideal equipment for controlling atmospheric dust pollution.

Exhaust gas desulfurization refers to the removal of sulfur oxides (SO2) from flue or other industrial waste gases. Desulfurization equipment generally refers to a series of equipment used in power industry production to remove sulfur from coal and prevent the production of S02 during combustion.
