Research and application of an axial cyclone condensationair filtration device

At present, the coarse and medium-efficiency filtration method commonly used in the process air conditioning system in the cigarette industry has the problems of rapid decline in filtration efficiency and frequent filter cleaning and replacement. In this paper, it is proposed to replace the traditional contact filter with a bipolar ionizer and an axial cyclone dust collector unit. The application results show that the device can improve the filtration efficiency of ultrafine tobacco dust particles such as nicotine and tar, realize online automatic ash cleaning and keep the pressure difference between the two sides of the filter constant, and can truly achieve maintenance-free.
