    Bag Filters

    Corrotech supplies most advanced industrial bag filters that are used in the Zinc Fume Extraction system. The zinc fumes enter uniformly by the side distribution chamber from the bottom, where heavier particles drop immediately into the hopper. Lighter particles rise and are collected on the outer side of the tubular bags while clean air passes through the fabric and is collected to the fan by the filter top plenum and outlet side chamber.

    Bag cleaning is automatic by means of compressed air emitted by solenoid valves. Solenoid valves periodically emit a burst of compressed air into the bags. This pulse of air rapidly expanding down into the filter bags sets up a shock wave, which flexes the felt. Dislodged dust drops into the hopper, where it is discharged. The cleaning cycle is automatically repeated by an adjustable timer.

    The bag filter unit consists
    • Series of suction ducts with lateral slot suction hoods, located along the pickling tanks walls and under the walking grids, Polypropylene made
    • Main ducts connecting the previous suction ducts to the fans, Polypropylene made
    • Electric driven fan, Centrifugal and acid proof type
    • Turbulent contact scrubber for hydrochloric acid gas neutralization, Polypropylene made. In this scrubber the packing consists of two beds of low density spheres, free to move between upper and lower retaining grids.
