Exporting Stainless Steel Chevron Plate Mist Eliminator, Vane Pack Demister, Desulfurization Tower Droplet Eliminator

Chevron plate demister is mainly used for flue gas desulfurization and separation of droplets in waste gas. It has the advantages of simple structure, high capture efficiency for medium size and large size droplets, low pressure drop, easy flushing, open structure, easy maintenance and low cost.

Mainly there are two types of plates, 2 pass type (170mm net height and 200mm total height with frame), 3 pass type (230mm net height and 250mm total height with framesm).  The shape and size of mist eliminator can both be customized as per order. Square shape, round shape, etc.

The 3 pass type has higher de-misting efficiency. It is always used in less solid fouling circumstances because of a little harder washing than 2 pass type.

A method to estimate weight of stainless steel vane pack demister

For example, if the required plate distance is 25mm, it takes about 37 pcs of 1m length corrugated plates and necessary frames to build a 1m*1m chevron mist eliminator. Then the mist eliminator unit weight =37*single plate weight+frame weight (properly estimated).

Working principle of vane pack demister: 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 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.
