Introduction to the types of metal mesh materials used in wire mesh demister products
Wire mesh demister is also called wire mesh demister, demister, mist collector, which is used to separate the mist entrained by the gas in the tower to ensure the efficiency of filtration and increase the production capacity by 5%.
The main materials of wire mesh demister are: B2, B3, C-276, 2205, 2507, F46, titanium, nickel, N5, N6, titanium wire mesh, etc.
Wire mesh demister is generally installed on the top of the tower. If a wire mesh demister is installed between the tower plates, it can not only ensure the mass transfer efficiency of the tower plates, but also reduce the distance between the plates. The wire mesh demister standard is suitable for use as a vapor-liquid separation device for vertical cylindrical equipment in chemical, petroleum, medicine, light industry, metallurgy and other industrial production. At present, wire mesh demisters are used in imported ethylene, synthetic ammonia and chemical fiber production equipment.
Material selection
The wire mesh used in wire mesh demister products has three types of materials to choose from: metal, non-metal, and metal and non-metal interlaced:
