Stainless Steel 316l Wire Mesh Demister For Gas Liquid Mesh Filter
Stainless Steel 316L Wire Mesh Demister For Gas Liquid Mesh Filter
1. Wire Mesh Demister Introduction
A wire mesh demister, also known as a mist eliminator or mesh filter, is a type of gas-liquid separation device that is used to remove liquid droplets from a gas stream. It consists of a mesh pad made up of multiple layers of knitted or woven wire mesh, which is designed to capture and hold liquid droplets as they pass through.
The gas-liquid mixture flows through the wire mesh pad, and the liquid droplets are captured on the wire surface due to the mesh's high surface area and capillary action. Once the droplets are captured, they coalesce and form larger droplets that are heavy enough to fall out of the gas stream due to gravity. The gas stream then passes through the wire mesh pad and exits with minimal liquid content.
Wire mesh demisters are commonly used in various industries, including oil and gas, chemical processing, and power generation, where the removal of liquid droplets from gas streams is critical to ensure efficient and safe operation of equipment. They are also used in environmental applications, such as air pollution control, to remove liquid droplets from exhaust gases before they are released into the atmosphere.

3. How does a demister pad work?
(1) A vapor stream carrying entrained liquid droplets passes through a demister pad. The vapor moves freely through the knitted mesh.
(2) The inertia of the droplets causes them to contact the wire surfaces and coalesce.
(3) The large, coalesced droplets formed in the mesh ultimately drain and drop to the vessel bottom.
4. Advantages of PP Demister Pad
1. Various types and diameters.
2. Simple to install and uninstall.
3. Acid and alkali resistance.
4. Corrosion resistance
5. High filtering
6. Light weight
