Stainless steel wire mesh is often used as chemical packing mesh. Widely used in petrochemical, fine chemicals, fertilizers, pesticides, environmental protection, spices and other occupations in the tower as a filler. The stainless steel packing net is a necessary part of the packing tower in the chemical industry. Its basic function is to increase the mass transfer coefficient by adding the touching area of gas-liquid two-phase, and to improve the turbulence degree of liquid so as to facilitate the mass transfer and heat transfer. The packing tower is a mass transfer equipment which uses the packing in the tower as the touching component between gas and liquid. The tower body of packed tower is a vertical cylinder, the bottom of which is equipped with packing support plate. The basic requirements of stainless steel packing net tower for packing: 1. High Mass transfer efficiency requires that packing can supply large gas-liquid contact surface. That is, require a large specific surface area, and require the packing surface is easy to be wet by the liquid. Only wet, the appearance is the gas and liquid touch the appearance. Production capacity, gas pressure drop is small. Therefore, it is required that the vacancy rate of the packing layer is large. Do not move causing drift and furrow flow. 2, durable with outstanding corrosion resistance, higher mechanical strength and necessary heat resistance; 3, selection of simple, cheap.
