POWER CONDITIONING OF INSERTING BANDGAS TO AN ELECTROSTATIC POWER FILTER

摘要

Disclosed herein is a system for improving dust collection efficiency at a sinter band device, the system comprising a sinter band with material handling stations and auxiliary equipment, operative to sinter a metal or metal ore; a primary electrostatic precipitator operative to remove primary dust from a primary gas stream that has passed through a bed of sintering material on the sinter band; a secondary dust collection device operative to remove secondary dust from a secondary gas stream emanating from one or more suction points at the material handling stations and the sinter band; where the secondary dust has a lower electrical resistivity than the primary dust; and a dust transportation line that is operative to transport secondary dust to the primary gas stream downstream of the sinter band, and injecting it at a position upstream of the primary electrostatic precipitator and/or directly into the precipitator itself.
