Wire Mesh Demister - Sp/hp/dp/hr Mesh Types , High Efficiency Foam Removal At 97%

Wire Mesh Demister is mainly used to separate drops of the diameter between 3I M to 5I M, 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 inter texture 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.
HG/T21618-1998
The new standard unites the three installing modalities of ascension pipe type, reduction diameter type and full diameter type, puts forward four types of meshwork, namely SP\HP\DP and HR, expands the variety of the material to be used. It increases more types in size.
