φ1000 mm Round Shape SS304 Vane Pack Mist Eliminator
1. How does Hualai vane pack mist eliminator works?
when the gas containing mist flows through the demister at a
certain speed, because of the inertial impact of the gas, the mist
and wave plate collide and are attached to the wave plate surface.
The multi fold structure of the wave plate of the mist eliminator
increases the chance of catching and gathering the mist, and the
undeleted mist will catch and gather at the next turn through the
same function, so it will work repeatedly, thus greatly improving
the efficiency of mist eliminator. After the gas passes through the
chevron mist eliminator, there is basically no mist.
2. Advantages of vane pack demister / mist eliminator
1. Lower pressure drop.
2. Resistance to fouling.
3. High tensile strength.
4. Durable and long service life.
5. Custom-made design available.
6. High filtering and separating efficiency.
7. High capacity. It has 30% to 100% more capacity than the wire
mesh mist eliminator.
3. Applications of vane pack demister
Vane pack demister is widely used to separate entrained liquid
droplets from gas stream, in which the liquid droplets are 8 μm or
larger. When the gas stream passes through the vane pack demister
and change direction, the liquid droplets are unable to change
direction as quick as the gas due to their momentum. So the liquid
droplets impact on the chevron blade and then coalesce and form
large droplets until drain away.
In the special environment, where there is some small solid
particles, vane pack mist eliminator is the better choice for
liquid and gas separator than the wire mesh demister.
4. When to use vane type mist eliminator instead of mesh pad?
Larger droplets;
Surge Buffeting;
Foam Problems
Severe Corrosion;
High Liquid Load;
High Gas Velocity;
Low Pressure Drop;
Clogging Particulates;
Accumulated Residues;
Extremely Viscous Liquid.

Removal of very small droplets can be achieved using a two stage
mist eliminator by fitting a mesh pad to the upstream face of the
unit to coalesce droplets as small as 4 to 5 microns into droplets
in the size range which are easily removed by the vane separator.
