Product Description

Demister pad, also called mist pad, wire mesh demister, mesh mist eliminator, catching mist, mist eliminator. Demister Pads are woven with multi layer knitted mesh in different densities. It is used in gas entrained mist separation column to guarantee the filtering efficiency.

Wire mesh demister,also known as a wire mesh mist eliminator, is a kind of vapor liquid separating device. It is widely used in the chemical, petroleum, medical, light, metallurgy and environmental protection industries.It is most often used to separate liquid drop with diameter of more than 3-5 μm in the separation tower.The operating principle is showed in the fig at the right side. When the gas with liquid drops rises at a certain speed, passing through the wire mesh on the grid bar, the inertia of the rising drops make them collide with the wire and then adhere to the surface of the wire. The drops on the wire will diffuse and subside. It makes the drops form bigger ones and then flow along the wire to the intertexture of the wire. Because the wire can be humidified, and because of the surface tension of liquid and the capillarity effect of the
wire, the drops will become bigger and bigger. They will be separated and fall when their own weight exceed the resultant force of buoyancy of the rising gas and surface tension of liquid. They will flow to the device of the container in the backward position.As long as the speed of the gas is properly controlled and with other proper condition, the efficiency of foam remove will be as high as 97% after the gas pass through wire-mesh demister. The purpose of removing foam will be achieved completely.
