SS316l York 421 Wire Mesh Demister Pad for Vaper-Liquid Filter 193kg/m3

Wire mesh demister comprises of wire mesh,wire mesh block of wire mesh grill and support device fixing mesh bliock.
Demister,generally set on top separation column,used for separating the gas entrained droplets in the column to ensure mass transfer efficiency,
reduce the loss of valuable materials and improve the operation of the compressor after the separation.It can effectively remove droplet beteen 3—5μm.
usage:Petroleum, chemical, light industry, medicine, metallurgy, aerospace, ship, environmental protection engineering distillation, evaporation, absorption and other processes in the gas-liquid separation, gas separation, mechanical equipment, oil and gas separation.

Key Specifications

• Material: Stainless Steel 304 (SS304). Provides excellent resistance to oxidation and moderate corrosion in various industrial environments.

• Diameter: 600mm. Precision-sized for medium-scale scrubbers or distillation columns.

• Construction: Knitted wire mesh (interlocking loops) supported by top and bottom grids (flat bars and round bars) to ensure structural integrity under pressure.

• Thickness: Standard thickness is usually 100mm to 150mm, though this can vary based on the required separation efficiency.

In a gas scrubber system, the demister is the final stage of treatment. Its primary roles include:

1. Gas Scrubbing & Absorption

In wet scrubbers, liquid is sprayed to neutralize contaminants. The demister sits at the top of the tower to catch the "carry-over" spray, ensuring the exiting gas is dry and the scrubbing liquid is recycled.

2. Equipment Protection

It prevents corrosive liquid droplets from reaching downstream equipment such as blowers, compressors, and turbines, significantly reducing maintenance costs and mechanical wear.

3. Environmental Compliance

By capturing entrained liquids that may contain pollutants or chemicals, the demister ensures that the exhaust gas discharged into the atmosphere meets environmental safety standards.

4. Product Recovery

In processes involving expensive solvents or chemicals, the demister captures these droplets from the vapor stream, allowing them to be returned to the process rather than being lost as waste.
