Product Description

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.
