【Abstract】 This paper elaborates a new type of two-stage vertical mobile particulate layer precipitator. The key technologies are originally created outbed ash removal and gas stream transportation and filter-cycle systems.A practical-new type patent has been obtained for the precipitator in 1991 in China.It has wide applications and high collection efficiency and has no secondary pollution.It is adaptable for controlling pollution sources such as dust-lader flue gas and can reduce the pollution to a level under emission control standard.更多还原
