SS316L OEM Knitted Mesh Demister Foam Separator for Gas Liquid Separation

Wire mesh demister pad: (also known as wire mesh defogger, bubble trap) is a highly efficient gas-liquid separation device widely used in chemical, petroleum, sulfuric acid, pharmaceutical, light industry, metallurgy, machinery, construction, aviation. In the industries such as maritime transport and environmental protection, in the production equipments such as ethylene, synthetic ammonia and chemical fiber imported from abroad, the use of wire mesh defoaming as a gas-liquid separation device is also used. It is mainly used to separate droplets having a diameter of more than 3 μm to 5 μm.
Features of wire mesh demister: 1. Simple structure, light weight, large void ratio, small pressure drop 3. Large contact surface area and high defoaming efficiency 4. Easy installation, operation and maintenance 5. Long service life . It is a special wire mesh demister in the sulfuric acid industry.

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.
