Welding smoke electrostatic precipitator performance parameters

Welding smoke electrostatic precipitator performance parameters of the welding smoke electrostatic precipitator main parameters including electric field the flue gas flow rate, the effective cross-sectional area, than the dust collection area, electric field, electric field length, plate spacing, line spacing, the critical voltage, drive into the speed, the efficiency of dust collection, etc. Drive into the speed: dust particles with airflow movement in the welding smoke electrostatic precipitator, electric field force, fluid resistance, air dynamic pressure and the combination of gravity dust particles called subsidence by gas flooding to the electrode. Settling velocity is under the effect of electric field force between dust particles and fluid resistance after reaching balance of speed. Settling velocity is often called flooding into the speed, the size of its load obtained by the power to decide. Welding smoke precipitator flue gas temperature gas temperature can also change the electrical resistance of the dust, and the direction of change but there are several possible: surface resistivity increases with temperature rise, This only in the low temperature section) ; After reach a certain temperature, volume resistance, by contrast, in the junction temperature has a period of transition region, namely, surface and volume resistivity of interaction area. The electric working temperature can be selected by dust resistivity gas temperature curve. Flue gas temperature is performed in the gas viscosity influence. Gas viscosity increases with the rising, this will affect the speed drive into the decline of gas temperature is higher, its density is lower, strengthen the ionization effect, breakdown voltage drop, spark discharge voltage is falling.
