The ceramic cross baffle ring filler was also developed based on the idea of increasing the specific surface of the filler to enhance the mass transfer efficiency. Generally speaking, this kind of packing is only suitable for neat stacking due to its large size. At present, it is only used for the distribution layer of support at the bottom of the tower of random packing. Φ cross baffle ring of 80-150 - mm specification can be as support materials, void fraction is more than 60%, the number of the whole number.
● ceramic cross ring because of its high density and excellent resistance to acid and heat resistance, and can withstand except hydrofluoric acid, organic acid and organic solvent corrosion.
Low cross ceramic ring is a modified form, ceramic raschig ring than ceramic raschig ring has a larger specific surface area and better compressive strength, has excellent acid resistance and heat resistance, can and ability of various inorganic acid except hydrofluoric acid, organic acid and organic solvent corrosion, and can be used in high temperature or low temperature environment, so its use range is very wide. Ceramic cross ring can be used in drying tower, absorption tower, cooling tower, washing tower in chemical industry, metallurgical industry, coal and natural gas industry, industrial oxygen production industry, and so on.
