Ceramic Raschig Ring Packing

The outer diameter and height of the packing ring are equal, the structure is simple, and the price is low, but there are strongholds such as uneven liquid distribution and serious wall flow channeling. Nowadays, corrosion-resistant ceramic Raschig rings are generally used in the acid industry. The main function is to provide a sufficient contact surface for the gas-liquid two-phase.

At present, there are many types of tower packing used in water treatment, including liquid surface covering balls, multi-faceted hollow balls, suspension ball packings, Pall ring packings, etc. Today we will introduce Raschig ring packing, which is also very early Fillers used in water treatment. Ceramic Raschig ring packing is a kind of tower filling material, which has acid and heat resistance, high and low temperature resistance, anti-aging characteristics, and can resist corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid (HF). It is used in various high and low temperature occasions, and is widely used in washing towers, cooling towers, acid recovery towers, desulfurization towers, drying towers and absorption towers in metallurgy, chemical industry, fertilizer, acid production, gas, oxygen production, pharmaceutical and other industries. Features: Due to the high porosity of ceramic Raschig ring packing, large gap, large flux and small resistance, the gas and liquid in the packed tower can pass freely, and the distribution of gas and liquid in the packing layer is relatively good, especially the packing The inner surface of the ring is easily wetted by liquid, no matter what its orientation is, some of the liquid sprinkled on the packing will flow along the outer wall, and some will flow along the inner wall. In this way, the degree of dispersion of the liquid is increased, and the utilization rate of the inner surface of the filler is improved. Therefore, it not only has a large passing capacity and a low pressure drop, but also has a high mass transfer and separation efficiency of the tower.
