The alumina content of corundum raschig ring packing is generally 90%-95%, and the high-aluminum corundum raschig ring reaches more than 90% by increasing the aluminum oxide content. Corundum raschig ring contains a large number of corundum crystals, the strength is much higher than the ordinary raschig ring, and the high temperature resistance is also higher (using more than 1430℃. Generally, the use temperature of ordinary raschig ring is 1000 ° C), which can withstand rapid temperature changes when used above 1200°C, and has excellent thermal shock resistance, which is not easy to break and cause blocking bed.
Corundum raschig ring packing has high mechanical strength, high temperature resistance, wear resistance, acid and alkali chemical corrosion resistance. It solves the problems that common ceramics are brittle and easy to crack in case of high temperature and temperature change. And because there is a straight round hole in the middle of the raschig ring, it has large and uniform voidage, strong steam and liquid distribution ability, large flux, small resistance drop and small pressure drop. Loved by users.
Inert alumina corundum raschig ring is widely used in petroleum, chemical, natural gas, nitric acid oxidation furnace, natural gas and environmental protection and other industries of high temperature occasions and thermal shock occasions, such as drying tower, absorption tower, cooling tower, scrubber, recycling tower and so on.
Corundum raschig ring is used as the covering support material of catalyst in the reactor. In addition to the above-mentioned physical and chemical properties such as high temperature resistance, resistant to acute heat and cold, wear resistance and non-crushing, it also increases the distribution point of gas and liquid, it can support and protect catalysts with low strength but high catalytic activity.
