The mesh demister is a gas-liquid separator that removes entrained mist and moisture when gas passes through the mesh pad of the demister. The HG/T21618-1998 standard was revised based on the original chemical industry standards HG5-1404-81, HG5-1405-81, and HG5-1406-81, incorporating practical usage experience of the mesh demister and technology improvements from the introduced equipment.

The Mist Eliminator is composed of two parts: the gas-liquid filter mat (consisting of several mesh blocks) and the supporting components. The mesh blocks are made up of several layers of corrugated gas-liquid filter mesh, grates, and spacers. The gas-liquid filter mat used in the production of the mist eliminator is woven and supplied by Anping Jiuxin Company according to the mist eliminator standards. The supporting components can also be manufactured and provided by Anping Jiuxin Filter Mesh Co., Ltd., but this should be specified at the time of ordering.

Selection of top-mounted and bottom-mounted mist separators: Choose a top-mounted mist separator when the inlet is located above the mist separator or when there is no inlet but a device flange is present. Select a bottom-mounted mist separator when the inlet is positioned below the mist separator.
