ISO 9001-2015 431 Wire Mesh Demister Mist Eliminator For Chemical Columns
431 Demister Mist Eliminator Wire Mesh Demister Pad For Chemical Columns
Demister Pad Description
Wire mesh demister is a kind of vapor-liquid separating device, It is used to remove the steam, entrained droplets in the processing equipment when the gas go through demister wire pad, with big surface, high demisting efficiency, and long working life, good resistance.
* Wire Mesh Demister Material : Stainless Steel 304L, 316L, Monel, Nickle, ect.
* Wire Diameter: 0.08--0.50mm, But 0.2mm-0.25mm are the most common wire diameter specifications.
* Width: 40mm, 80mm, 150mm, 200mm, 300mm, 400, 500mm, 600mm, 800mm, 1000mm, 1200mm, 1400mm, etc. Less than 1000mm width are the most common width and are easy to make. Also available upon customers' request.

Feature of demister pad (mist eliminator)
· Most cost effective solution when equipment sizes are set by other requirements
· High efficiency with low drop pressure
· Easy to install in all types of process equipments
· Emergency delivery available
The demisting process of Demister pad
The operating principle behind the mist eliminator is simple. As the wet vapour stream rises through layers of contracting surfaces within the knitted and crimped wire matrix, entrained as they continuously impact each surface. The gas within the vapour stream continues to rise as the heavier liquids separate, attach and coalese into droplets within a mesh. as the droplets grow, so does their weight until they fall to the bottom of the vessel due to gravity. Liquid accumulations can then be drained out of the bottom as, the gas is routed through the top of the Vessel.
