Directly discharging the tail gas containing dust particles into the air is likely to cause air pollution. At the same time, the dust particles contain useful components, and direct discharge is also a waste of resources. Therefore, there is a need for a device that is conducive to recovering the dust particles discharged from the tail of the rotary kiln. Summary of the Utility Model
