Chemical filler is the basic component of gas-liquid contact in packed towers. It is widely used in many industries, has excellent acid and heat resistance, and can resist corrosion of inorganic acids, organic acids and organic solvents other than hydrofluoric acid. For various high and low occasions, its performance is the main factor that determines the operating performance of packed towers. Chemical fillers include filling grains, packing open hole ball, alumina filling bead, ceramic raschig ring, ceramic filling gear and so on.
Chemical filler has excellent acid and heat resistance, can resist the corrosion of inorganic acids, organic acids and organic solvents other than hydrofluoric acid, can be used in a variety of high and low occasions, a wide range of applications can be used in chemical, metallurgy, gas Drying towers, absorption towers, scrubbers, and regeneration towers in the oxygen industry. According to the material can be divided into three categories: ceramic fillers, plastic fillers, metal fillers.
