Wire Mesh Demister Pad

The wire mesh demister pad is a gas-liquid separation device. The gas passes through the wire pad of the demister to remove the entrained mist.
The wire mesh demister pad can not only filter out larger liquid foam suspended in the airflow but also filter out smaller and tiny liquid foam.

Material: Stainless steel wire 304, 304L, 321, 316, 316L, 2205, 2507, pure copper wire, pure nickel wire, pure titanium wire, Monel 400, Inconel, Hastelloy C-276, etc.
Structure: The wire mesh demister pad is mainly composed of a knitted wire mesh, a wire mesh grid, a wire mesh block, and a supporting device for fixing the wire mesh block.
Application: It is widely used in gas-liquid separation devices in chemical, petroleum, tower manufacturing, pressure vessels, and other industries.

How does a wire mesh demister pad work

When the gas with mist rises at a certain speed through the knitted wire mesh demister pad, due to the inertia of the rising mist, the mist collides with the wire mesh filaments and is attached to the surface of the filaments.

The diffusion of mist on the surface of the filaments and the gravity sedimentation of mist makes the mist form larger droplets that flow along the filaments to the intersection of the two filaments.

The wettability of the filaments, the surface tension of the liquid, and the capillary action of the filaments make the droplets larger and larger until the aggregated droplets are so large that the gravity generated by themselves exceeds the combined force of the rising force of the gas and the surface tension of the liquid, and the droplets separate and fall from the filaments.

It has a simple structure, small size, high defoaming efficiency, small resistance, lightweight, and is easy to install, operate, and maintain. The wire mesh demister has a capture efficiency of 98%-99.8% for mist with a particle size of ≥3~5um, and the pressure drop of the gas passing through the demister is very small, only 250-500Pa, which is beneficial to improving the production efficiency of the equipment.

Application of wire mesh demister pad

  • Vacuum distillation towers in refineries: Wire mesh demisters allow operation at higher flow rates and improve the quality of oil and gas when cutting deep into atmospheric heavy oil.
  • Absorption towers: Wire mesh demisters can completely and thoroughly remove various mist absorption oils, glycols, and amine solutions to obtain clean, dry gas.
  • Evaporators: Wire mesh demisters can avoid valuable product entrainment losses and produce high-quality condensate (water) suitable for boiler feed water or use in production processes.
  • Distillation towers: Using wire mesh demisters to treat vegetable oils, tall oils, fatty acids, glycerin, lubricating oils, mineral oils, and extracts from asphalt, organic intermediates, refined chemicals, etc. can improve product performance.
  • Dust collectors: Wire mesh demisters have a significant dust removal effect like wet dust collectors.
  • Electronic shielding pads: If wire mesh demisters are used as pads for electrical parts, radio wave interference can be completely prevented.
  • Buffer: Wire mesh demister used as a buffer will help reduce vibration and keep other mechanical equipment in a completely stable state.
