Wet Electrostatic Precipitator: Advanced Flue Gas Purification Equipment for Industrial Emission Control

The wet electrostatic precipitator(WESP)is a high-end industrial flue gas deep purification equipment,which is specially used for treating ultra-fine particulate matter,acid mist,tar fog,water mist and other pollutants that are difficult to remove by conventional dust removal equipment.It is widely applied in industrial fields with strict flue gas emission standards such as thermal power plants,waste incineration plants,chemical plants,coking plants and biomass power plants.Different from dry dust removal equipment,the wet electrostatic precipitator adopts wet electrostatic adsorption principle for purification.The equipment generates high-voltage electric field between the anode and cathode tubes,making the passing flue gas ionize,and the pollutant particles are charged and adsorbed on the electrode plate.Through the circulating water flushing system,the adsorbed pollutants are washed down into the water tank for centralized treatment,realizing thorough separation of pollutants and flue gas.This working mode avoids the dust re-entrainment problem of dry electrostatic equipment,and the purification effect is more thorough and stable.The equipment has ultra-high purification capacity for ultra-fine dust particles below 1 micron,with a removal efficiency of fine particulate matter,acid mist and tar fog up to 90%,which can effectively help enterprises achieve ultra-low flue gas emission standards.The whole equipment operates stably with low resistance and small flue gas pressure loss,which will not affect the normal operation of the front-end flue gas treatment system.The internal electrode system adopts anti-corrosion and wear-resistant materials,which can adapt to high-temperature,corrosive and high-humidity flue gas working environments,with long service life and strong corrosion resistance.Equipped with automatic water circulation system and intelligent high-voltage power supply control system,the equipment realizes automatic water supply,automatic flushing and voltage automatic adjustment,with high degree of automation and low manual operation cost.The wastewater generated during operation can be recycled after sedimentation and filtration treatment,realizing energy saving and environmental protection,and no secondary waste pollution is produced.The wet electrostatic precipitator has flexible structural design,which can be customized according to different flue gas volume,pollutant concentration and emission requirements.It can be used as terminal deep purification equipment to cooperate with desulfurization and denitrification equipment to form a complete flue gas treatment system,effectively solving the problem of excessive ultra-fine particulate matter and aerosol emissions in industrial flue gas,helping enterprises meet international environmental protection emission standards and reduce environmental pollution pressure.
