Zinc Fume Extraction System

A hot dip galvanizing factory produces white vapours as steel is dipped in molten zinc throughout the operation. Due to the chlorine and dispersed ash particles in the vapours, they are particularly dangerous. It might also be regarded as unhealthy if inhaled. Additionally, they shorten the life of the shed and the overhead cranes. It is obvious to create a system for fume abatement and discharge as a result. To absorb such fumes by help of ducting system and transfer it to fume extraction system. There are two different system to suction zinc fumes Generate at the time of dipping of materials in to Zinc bath. The zinc (white) fumes produced during the dipping process are effectively drawn in through ducting, and after leaving the cyclone, all zinc dust is dropped into a dust collector. The fume is then diverted to the scrubbing unit, where the fumes are neutralised and zinc-fume-free air is released into the atmosphere through the chimney. The technology produces great results to satisfy the pollution control agencies’ standards for emission control.

One is Lip type Ducting system and
Second one is Fully covered fume extraction system

Lip Type Ducting System

Lip type Ducting system will be fabricated with mild steel sheet according to length of Kettle and place near to top of Kettle flange to suck the white fumes.

  • Lip type Ducting system will be fabricated with mild steel sheet according to length of Kettle and place near to top of Kettle flange to suck the white fumes.
  • The lip-type suction ducts are rectangular and mounted on the sides of the kettle. They are laterally positioned over the sides of the furnace using support structures constructed of thick mild steel sheets and sprayed with temperature-resistant paint. The white vapours produced by the kettle are extracted through these ducts. The suction slots’ size is determined by the extraction area and the volume of emitted fumes.

Zinc Furnace Fume Enclosure

A zinc furnace fume containment technology that virtually eliminates fumes, intelligently constructed enclosures from which only the barest amount of fumes can escape. The section is connected to a dust-collecting cyclone. The cyclone is then connected to a wet scrubber or a bag filter, where fumes are cleansed for effective filtering before leaving the enclosure and entering the atmosphere.
