Industrial Bag Filter
The zinc fume during work piece get galvanizing, go into the filter system. In the industrial bag filter, there are a lot of filter mediums inside of it. When zinc smoke air get through, the filter mediums get filled with particles(zinc particles). When the pressure difference in the filter exceeds a certain level, the filter mediums are shaken out by vibration. The zinc powder fall into the container at the bottom of bag filter. Then, the clean filter is ready to absorb zinc particle again.
This zinc powder from zinc fume, can be used as material for ZnCl2 to achieve recycling.
