Product Description

SS304 316 Wire Mesh Mist Eliminator Vane-Type Demister for Industrial Oil Mist Separator 
Metal Demister is an efficient gas-liquid separation device used to remove entrained liquid droplets or mist from gas streams. It is widely applied in industries such as chemical processing, petroleum, environmental protection, and power generation. Its core function is to eliminate fine liquid droplets from gases through physical interception and inertial impaction, ensuring gas purity or meeting downstream process requirements.

1. Structural Types
   

   • Wire Mesh Demister: Made of multiple layers of metal wire mesh (e.g., stainless steel, titanium alloy, copper) compressed together, forming dense pores and tortuous pathways to capture and coalesce droplets.

   • Vane-Type Demister: Consists of parallel corrugated or baffle plates that separate droplets by altering gas flow direction.

   • Hybrid Demister: Combines wire mesh and vane structures for high liquid-load or high-velocity applications.
      

2. Common Materials:

   • Stainless Steel (304/316L): Corrosion-resistant, suitable for most industrial environments.

   • Titanium/Nickel Alloys: Used in highly corrosive media (e.g., chlor-alkali industry).

   • Galvanized Steel or Aluminum: Cost-effective for mild conditions.
     
      

     Working Principle

   • Inertial Impaction: Gas carrying droplets passes through the mesh or vanes, where droplets collide and adhere to the surfaces.

   • Coalescence Effect: Tiny droplets merge into larger ones on the mesh surface and fall due to gravity.

   • Centrifugal Separation (Vane-Type): Repeated changes in gas flow direction force droplets to separate by centrifugal force.

   •  

     Features and Advantages

   • High Efficiency: Removes droplets as small as 1μm, with separation efficiency exceeding 99%.

   • Low Pressure Drop: Optimized design minimizes airflow resistance, reducing energy consumption.

   • High Temperature/Pressure Resistance: Metal construction withstands harsh conditions (e.g., hot flue gas, high-pressure reactors).

   • Long Service Life: Resistant to corrosion and wear, requiring minimal maintenance.
     
      

     Applications

   • Chemical Industry: Gas-liquid separation in distillation towers, absorption columns.

   • Petroleum Refining: Gas treatment, natural gas dehydration.

   • Environmental Engineering: Mist elimination after flue gas desulfurization (FGD).

   • Power Generation: Air filtration for gas turbines.

   • Pharmaceutical/Food Industries: Sterile air purification.

   • Selection Considerations

   • Gas Properties: Flow rate, temperature, pressure, corrosiveness.

   • Droplet Characteristics: Particle size distribution, viscosity, concentration.

   • Installation Space: Layout in vertical or horizontal vessels.

   • Pressure Drop Requirements: Choose structure based on energy constraints.

   •  

     Maintenance and Notes

   • Regular Cleaning: Prevents clogging (especially with solid particles).

   • Corrosion Inspection: Periodic replacement needed in acidic or high-humidity environments.

   • Installation Orientation: Ensure proper alignment with gas flow direction (e.g., vane-type has specific flow requirements).
