Environmental Friendly Hot Dip Galvanizing Furnace Equipment
Production Line Galvanizing White Fume Treatment Supplier
We supply reliable, high-performance, environmentally friendly,
technological, and modern galvanizing factories.
The white fume is produced from the hot dip galvanizing process.
Generally, the molten zinc surface can quickly form an oxide layer,
and the amount of fume is less. But once the workpiece dips in and
takes out of the zinc kettle, the fume increases suddenly because
of the stirring and volatilization of the fluxing agent.
Characteristics of the white Fume
During the pretreatment and galvanizing process, hot-dip
galvanizing projects will produce more dust (zinc) and acid and
alkali gases than other industries, which will have a considerable
impact on the surrounding environment and the health of workers.
The fume generated during the galvanizing process contains a large
amount of zinc and zinc oxide particles and is emitted
intermittently and instantaneously.
White fume bag-type filter
The fume treatment part consists of a shell, filter bag, dust
hopper, dust discharging device, bracket, and pulse dust cleaning
system. When the dust-containing fume enters the air inlet, it
passes through the inner filter bag, and the dust is trapped on the
outer surface of the filter bag. The purified gas enters the clean
air chamber at the upper part of the filter chamber and is
collected in the air outlet pipe for discharge. Each row of filter
bags is cleaned in turn according to a given time interval. Each
row of filter bags corresponds to an electromagnetic pulse valve.
When cleaning, the pulse valve opens and sprays water-free and
oil-free high-pressure clean air into the corresponding row of
filter bags to remove the dust on the outer surface of the filter
bag.
