Ceramic random packing in packed tower has those advantages
There are many kinds of chemical fillers. At present, the most used tower fillers in industrial production are ceramic fillers, including ceramic structured fillers and ceramic bulk fillers:
Today we will briefly introduce ceramic bulk fillers: ceramic bulk fillers mainly include ceramic Pall rings, ceramic Raschig rings, ceramic ladder rings, ceramic heterosaddle rings, ceramic conjugate rings, ceramic word rings, ceramic cross baffle rings, Ceramic three-girl rings, ceramic plum rosettes, ceramic washing rings, light ceramic fillers, ceramic saddle rings, ceramic gear rings and ceramic flat rings can also be customized according to customer requirements. And with the requirements of industrial development, the structures of these commonly used types of ceramic fillers are also changing accordingly. When we are exploring ceramic fillers, we can choose some process production methods with details and instructions according to actual needs, and produce more useful ceramic fillers according to this form. This use effect will be better.
Bulk ceramic fillers are cheaper due to mature raw materials and production processes, stable performance and good surface wettability. In practical industrial applications, it has strong acid resistance, alkali resistance, corrosion resistance, high temperature resistance, is not easy to penetrate, will not chemically react with materials, and has low water absorption. It can resist the corrosion of various organic acids and alkalis except hydrofluoric acid and silicofluoric acid, and can resist the corrosion of almost all concentrations of inorganic acids and salts and organic media. However, because ceramics contain a large amount of silica and lye is easy to produce silicates, the corrosion resistance of ceramic fillers to phosphoric acid is poor.
Bulk ceramic packing is usually used in washing towers, cooling towers, recovery and regeneration towers, desulfurization towers in industries such as chemical industry, metallurgy, acid production, oxygen production, steel, electric power, papermaking, petroleum smelting, pharmaceuticals, gas, fine chemicals and water treatment. , drying tower, absorption tower, filter tank and reactor as lining material, filter material or packing in tower. It is widely used in gas absorption, gas scrubbing, liquid extraction and other processes.
