3D Pyramid Type Demister Mesh Pads, Mist Eliminator, Gas Scrubbing Media to Remove Particulates from Gas Flow

3D ‘pyramid-structured’ mesh demister

3D ‘pyramid-structured’ mesh demister is a reliable material in liquid separation processes, air pollution control or to remove particulates from a gas flow.

We use these ‘pyramid-structured’ meshes, with their 3D interlocked monofilament wires in duties where there is a need for a thermoplastic material with a meshpad strength sufficient to resist the operational duty of gasflow, liquid load and, often, soluble or insoluble particulates. The mesh has a very open structure which allows it to handle particulates for a long time before blockage would occur, and which is then quite easy to wash without damage, and re-use.

When used not as a demister mesh, but as a gas scrubber media, the open structure and mesh geometry facilitate the scrubbing process with irrigation sprays co-current or counter-current. Vertically or horizontally installed, the liquid and captured solids will easily flow off the monofilament wires and maintain the benefits of the low pressure loss that it offers in all cases.

Examples use of 3D ‘pyramid-structured’ mesh demister :

Demisting duty at the exit of a chemical process tail gas scrubber

Demisting duty at the end of a cross-flow or vertical gas scrubber in Phosphate and Nitrogen Fertiliser production

Particulate & gas scrubbing stage duties within a cross-flow or vertical gas scrubber in Phosphate and Nitrogen Fertiliser production (e.g. DAP, NPK, CAN & Urea)

Fume scrubbing of emissions from Chrome VI & other heavy metals processing

Abatement of HCl mist in Electronics industry

Demisting duty in Sulphuric Acid Drying and Absorbing Towers

The meshes can be supplied with support grids, frames or cassette frames in suitable materials such as PP, FRP, PFA, Stainless Steel, 904L & Tantalum.

3D ‘pyramid-structured’ mesh demisters consist of one or more precisely structured media layers. The use of one or multiple layers and the right choice of filament diameters in these layers allow you to achieve the highest efficiency at the lowest pressure drop (Dp) for your specific requirements. 3D ‘pyramid-structured’ mesh demisters are characterized by a large contact surface area and an unbeatable void space up to 97%!
