Transfer of material over belt conveyors often involves transfer points where dust is dropped from one point to the other.
Venting on top of Bins / Hoppers / Silo’s calls for a design which is customized for that particular application.
Specifically for such applications a Flush Mounted BagFilter is designed which is devoid of a Hopper, Support Structure and Dust Evacuation System.
Casing is directly mounted on top of the venting point, dust collected through the opening is dropped into the system below i.e. Directly into the Silo / Hopper / Bin or onto the conveying belt below.
An offline cleaning pulse jet bag filter consists of a number of chambers. Each chamber acts as an online pulse jet bag filter. The uniqueness of the design is in thefact that the supply of inlet gas to the chamber is stopped during cleaning temporarily. Dust falls into the hopper after the bagsare purged with compressed air, since there are no incoming gases into the chamber the dust collection is faster. Dust is evacuated using a rotary airlock valve. Remaining chamber’s continue toremain in operation and continue the filtration process.One after the other each chamber is made offline for bag filter cleaning & the process continues in cycles. Each chamber is made online or offline by operating pneumatically operated poppet dampers at the inlet & outlet of the chamber.
