wet electrostatic precipitatorBody structure:

Wet electrostatic precipitatorThe external components are made of ordinary carbon steel, and the inner surface is coated to prevent corrosion. During installation, attention should be paid to controlling the damage to the inner surface, especially at welding points, component connections, etc. The exterior of the shell does not require insulation because the flue gas temperature is below the saturation temperature, so the flue gas at the shell also hardly cools down. Overall, tubular dust collectors are more efficient, easier to arrange, and occupy more space than plate collectors.

Wet typeElectrostatic precipitatorMainly composed of import and export fluesdust collectorComposed of shell, guide plate, rectifier grille, anode dust collection plate, cathode wire, insulation box, flushing water system, power supply and control system. In terms of structural types, it is generally divided into two categories: plate type and tube type. The plate type dust collector has a flat plate shape, good water film formation, and evenly distributed corona wires between the plates. The main body is similar to a dry electrostatic precipitator and can handle horizontally or vertically flowing flue gas; The tubular dust collector is generally composed of multiple parallel circular or polygonal metal tubes, with corona wires distributed in the middle, and can only handle vertically flowing flue gas.

Weifang Luteng Dust Collector's WebsiteAdvantages and disadvantages:

Strong adaptability to dust, able to achieve high dust removal efficiency, and also suitable for handling high-temperature and high humidity flue gas; The problem of reducing the total carried water in the flue gas and decreasing the probability of gypsum rain formation is that the exhaust temperature needs to be lower than the adiabatic saturation temperature of the flushing liquid; It is difficult to use wet electrostatic precipitators at high dust and SO2 concentrations; No secondary dust; No vulnerable components such as hammering equipment, high reliability; It can effectively remove submicron particles, SO3 aerosols, and gypsum micro droplets, and has an effect on controlling PM2.5, blue smoke, and gypsum rain; Due to the high airflow velocity of the electric field in the electrostatic precipitator, the inclination angle of the ash hopper is reduced, and the equipment layout is compact; Necessary anti-corrosion measures; Although the flushing water of wet electrostatic precipitator adopts closed circulation, it needs to maintain balance with the desulfurization water system; Multiple components require corrosion-resistant materials and have not been mass-produced, resulting in high investment costs for individual products; The new unit needs to occupy a separate site behind the furnace, and there will be site layout issues for the renovation of the old unit.
