Galvanizing line exhaust air purification
The animation shows the schematic sequence of hot-dip galvanizing and the associated air purification system:
3. Immersion of the workpiece
As the workpiece begins to be immersed in the zinc bath a lot of smoke and dust are produced and minute particles of metallic zinc can also splash up. The exhaust air over the zinc bath contains up to 1 g of particles per cubic metre. The exhaust system is running at full speed. The exhaust air is sucked through the filter at a very high volume flow rate.
