Application
Demister used to separate liquid droplets carried by gas in the tower to ensure mass transfer efficiency, reduce valuable material loss, and improve the operation of the compressor after the tower, lower moisture content, and extend the lifespan of the compressor. Generally, a demister is installed at the top of the tower. It can effectively remove mist droplets of 3-5 micrometers. If a demister is installed between the tower trays, it not only ensures the mass transfer efficiency of the trays but also reduces the spacing between the plates. Therefore, the wire mesh demister is mainly used for gas-liquid separation. It can also be used for gas separation on air filters.

Operating Principle
As gas laden with droplets rises at a certain speed through the mesh, the inertia of the droplets causes them to collide with and adhere to the fine mesh wires. The spreading of droplets on the fine wire surface and their gravitational settling lead to the formation of larger droplets that flow along the wires to the intersection point between two wires. The wettability of the fine wires, the surface tension of the liquid, and the capillary action of the fine wires cause the droplets to grow until the accumulated droplet's weight exceeds the combined force of the gas's upward force and the surface tension of the liquid, at which point the droplet detaches from the wire and falls. After passing through the mesh demister, the gas is basically free of droplets. Separating droplets from the gas improves operating conditions, optimizes process parameters, reduces equipment corrosion, extends equipment lifespan, increases processing capacity, recovers valuable materials, protects the environment, and reduces air pollution. The simple structure and compact size of the mesh demister ensure high demisting efficiency, low resistance, light weight, and ease of installation, operation, and maintenance. The mesh demister has a collection efficiency of 98%-99.8% for droplets with a particle size of ≥3-5 μm, while the pressure drop across the demister is minimal, only 250-500 Pa, which is beneficial for improving equipment production efficiency.
