Wire Mesh Demister

The wire mesh demister is mainly composed of a wire mesh and a wire mesh grille to form a wire mesh block and a supporting device for fixing the wire mesh block. The wire mesh is a gas-liquid filter of various materials, and the gas-liquid filter is made of metal wire or Non-metallic wire composition. The non-metallic wire of the gas-liquid filter is made by twisting multiple strands of non-metallic fibers, or it can also be a single strand of non-metallic wire. The wire mesh demister can not only filter out the larger liquid foam suspended in the air flow, but also filter out the small and micro liquid foam. It is widely used in gas-liquid in chemical, petroleum, tower manufacturing, pressure vessel and other industries in the separation device.

Working principle: When the gas with mist rises through the wire mesh at a certain speed, due to the inertia of the rising mist, the mist collides with the filaments of the wire mesh and is attached to the surface of the filaments. 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 droplet larger and larger until the aggregated droplet is so large that its own gravity exceeds the resultant force of the upward force of the gas and the surface tension of the liquid When the droplet falls off the filament. After the gas passes through the wire mesh demister, there is basically no mist. Separation of mist in gas to improve operating conditions, optimize process indicators, reduce equipment corrosion, extend equipment service life, increase processing capacity and recover valuable materials, protect the environment, reduce air pollution, etc. The structure is simple, the volume is small, the foam removal efficiency is high, the resistance is small, the weight is light, and the installation, operation and maintenance are convenient. The pressure drop of the gas passing through the demister is very small, only 250-500Pa, which is beneficial to improve the production efficiency of the equipment.
