Bag filters of FR type
Bag filters are widely widespread and effective devices for dust collecting. They are used for dust separation from gases air in various industries: in ferrous metallurgy, chemical and petroleum industry, industry of construction materials, etc.
Bag filters represent devices with a body of the rectangular form. Bags with a filtering fabric are mounted in the body. Air filtration is carried out due to passage of the dusty environment through a fabric of the bag. In the process of accumulation (fine particles) on a filtering surface of a material pneumoresistance increases.
For regeneration (discharging of the collected layer in the bunker) process of autopurification due to the vibrations created by shaker is used. The unloading from the bunker is carried out through the gate. If customer wishes it is possible to establish dosing out (unloading) device for convenience of unloading process.
