Steel sintering machine cartridge filter at this stage, China's large steel sintering machine in the sintering process will emit large amounts of smoke, which contain nitrogen, sulfur dioxide, dioxins, dust and other substances. 280 square meters sintering machine, for example, material discharged to the atmosphere, including dust concentration 150mg / Nm3, this calculation, it will cause great pollution to the environment, at present, China's energy conservation to develop a detailed requirements and standards, environmental regulations in the continuous improvement of environmental protection put forward higher requirements, according to our current standards, the concentration of dust into the atmosphere must be less than 50mg / Nm3, and add a source of the company's steel plant sintering machine cartridge filter is an important part in fulfilling this requirement. Steel sintering machine flue gas cartridge filter works because the role of the induced draft fan is drawn through steel sintering machine and cartridge filter, and the role of negative pressure evenly and slowly through the cartridge. Flue gas passes through the filter bag, solid dust particles trapped on the outside of the cartridge, clean filtered air through the net gas collection chamber after the exhaust flue efflux. Using a pulse of compressed air which has been trapped in the cartridge from the cartridge and dust peel it falls within the hopper bottom, and then by transport equipment from the dust out of the hopper conveyor.
