Description

Technical Field

[0001] The utility model relates to the technical field of demisters, in particular to a wire mesh demister. Background Art

[0002] The wire mesh demister is a device used for gas-liquid separation. When the gas with mist passes through the wire mesh, the mist will collide with the wire mesh filaments due to inertia and adhere to the surface of the filaments. As the mist diffuses on the filaments and settles due to gravity, the mist will form larger droplets that flow along the filaments to the intersection of the two filaments. Here, the wettability of the filaments, the surface tension of the liquid and the capillary action jointly cause the droplets to grow and eventually detach from the wire mesh, thereby achieving gas-liquid separation. It is widely used in industries such as petroleum and chemical industry.
