Product Description

Wire mesh demister comprises of wire mesh, wire mesh block of wire mesh grill and support device fixing mesh block.
Demister, generally set on top separation column, used for separating the gas entrained droplets in the column to ensure mass transfer efficiency, reduce the loss of valuable materials and improve the operation of the compressor after the separation. It can effectively remove droplet between 3-5μm.
The demister between trays can not only guarantee mass transfer efficiency of the tray, but also reduce the board spacing .So wire mesh demister is mainly used for gas-liquid separation, and also gas separation ingas filter. In addition ,wire mesh can be used as a buffer of various types of instrument in instrument industry, and electronic jammers to protect against electrical interference.

Wire-mesh demister(or mist eliminator)is mainly used to separate drops of the diameter between 3μm to 5μm, 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.
