Abstract： |
An electrostatic bag closely hybrid dust remover and the operation method are mainly used for the flue gas disposal in a power plant etc. A grounding collecting plate is placed between a high voltage discharge electrode and the bag inside a dust removing room. An electrostatic dust removing area is formed by two sides of the high voltage discharge electrode and the grounding collecting plate; a filtering and dust removing area is formed by two sides of the bag and the grounding collecting plate. When the bag filters, the grounding collecting plate is closed, and the flue gas enters into the dust removing room and goes through the electrostatic dust removing area to arrive at the end of the grounding collecting plate and then enters into the filtering and dust removing area. When the bag reversely blows and cleans ash, the grounding collecting plate opens, the gas and dust for reverse blowing and ash cleaning pass through the grounding collecting plate directly and reach the electrostatic dust removing area, and the dust for reverse blowing and ash cleaning is collected by static electricity. Compared with the prior invention, the dust removal is separated into two steps: when the bag filters, an electrostatic dust remover is completely used to greatly reduce a dust-containing concentration of the flue gas which enters into the bag; when the bag reversely blows and cleans ash, the electrostatic dust remover is used to effectively remove the dust for ash cleaning. |
