Electrostatic Deashing Technique for Pitch Smoke Emitted from Carbon Roaster

Aiming at low density and high temperature pitch smoke with dustemitted from carbon roaster, dry and wet pre-handling and thenelectrostatic depurating are used to eliminate bigger size dust particle,lower temperature of smoke and reduce resistance firstly, then depuratepitch smoke with static electricity, which has advantage of automaticcontrol, saving energy with high deashing efficiency.
