The foam metal demister is used to separate the liquid droplets entrained by the gas in the tower to ensure mass transfer efficiency, reduce the loss of valuable materials and improve the operation of the compressor after the tower. Generally, a demister is installed at the top of the tower. It can effectively remove 3-50m droplets. If a room end device is installed between the trays, it can not only ensure the mass transfer efficiency of the trays, but also reduce the plate spacing. Therefore, the foam metal mesh credit device is mainly used for gas-liquid separation. It can also be used as an air filter for gas separation.

Working Principle
When the gas with the mist rises through the metal foam at a certain speed, due to the inertia of the rising mist, the mist collides with the intricate wire wall of the metal foam wire and is attached to the surface of the filament. The diffusion of the mist on the surface of the filament and the gravitational sedimentation of the mist make the mist form larger droplets and flow along the filament to the junction of the two filaments. The wettability of the filament, the surface tension of the liquid, and the capillary action of the filament make the rehearsal increase until the aggregated droplets are so large that their own gravity exceeds the resultant force of the upward force of the gas and the surface force of the liquid. When the droplet is separated from the filament, the falling gas passes through the foam metal demister, and basically does not contain mist and mist in the separated gas, so as to improve operating conditions, optimize process indicators, reduce equipment corrosion, and prolong equipment use. life, increase processing capacity and recover valuable materials, protect the environment, reduce air pollution, etc.
Advantages of mist eliminators over wire mesh demisters
1. The pores are more uniform and the pressure drop is smaller;
2. Larger specific surface area, higher capture rate and higher efficiency
3. Good strength, no need for additional brackets and other devices, which can reduce the volume of the product, and is more suitable for gas-liquid separation devices that require high-efficiency dust removal and mist removal and require a smaller volume.
