High efficiency multi hooks vane demister technical specification
1. Hualai vane demister project use,
The scope of the project includes the design of process, electrical, instrument control, water supply and drainage, HVAC and other systems, equipment selection, procurement, manufacturing and transportation, design, installation, construction and commissioning, trial operation, personnel training and final delivery and commissioning of Civil Engineering (structure) for the normal operation of closed coke storage system of delayed coking unit.
2. Advantages of vane demister
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. Working theoty of chevron plate mist eliminator
when the gas containing mist flows through the vane pack mist eliminator 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 diffusion of the mist on the surface of the corrugated plate and the gravity settlement of the mist cause the mist to form large droplets and move forward with the air flow to the turning of the corrugated plate. Because of the centrifugal force of the steering and its friction with the corrugated plate, the adsorption and the surface tension of the liquid, the droplets become larger and larger until the concentrated droplets are larger than the gravity generated by themselves, which exceeds the lifting force of the gas and the surface tension of the liquid. When the force is applied, the droplets are separated from the surface of the wave plate. 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.

5. Hualai experiences of chevron plate mist eliminator:
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.
