With the increasingly strict environmental regulations in China,gas dust removal technology has developed rapidly.Several promising dry and wet dust removal methods were emphatically introduced.The working mechanisms,influencing factors,advantages and limitations of different types of dust collectors were compared.And the research and application of combined dust removal technology were explored.Finally,the future development direction of gas dust removal technology was discussed.The cyclone dust removal technology has been widely applied in many industrial occasions,and the future breakthrough should be fo-cused on increasing the dust removal efficiency of the cyclone separator and reducing the operating pressure drop.The electrostat-ic dust removal technology is mature,but occupies a large area.The future direction of development will be the miniaturization of equipments,and the stability of equipments needs to be further improved.The wet dust removal technology has a high dust re-moval efficiency,but with a low utilization rate of washing water and the great heat energy loss,and there is a problem of second-ary pollution,and the energy conservation and environmental protection should be paid more attention in the future.The single dust removal technology can no longer meet the needs of modern industrial production,and the future development trend of gas dust removal technology will be focused on the development of efficient and economical combination dust removal technology.
