Commonly used tower packing can be divided into two categories: bulk packing and regular packing
Plastic packing materials include: polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF) and so on. It has good corrosion resistance, large void, large flux, low resistance, low energy consumption, low operating costs, light weight, easy loading and unloading, and can be reused. Especially suitable for petroleum, chemical, chlor-alkali, gas, environmental protection and other industries in the low and medium temperature (60-150 degrees) distillation, absorption and washing tower. There are Bauer ring, rectangular saddle ring, iso-saddle ring, step ring, Hale ring, **** yoke ring, flat ring, wreath, hollow floating ball, multi-faceted ball, mesh cage ball and cover ball.
Ceramic packing has excellent acid and heat resistance, can withstand the corrosion of all kinds of inorganic acids, organic acids and organic solvents other than fluorine oxygen acid, suitable for a variety of high, low temperature and strong corrosive occasions, can be used in chemical, metallurgical, gas, oxygen and other industries, such as drying towers, absorber towers, cooling towers, scrubbing towers, regeneration towers and so on. Metal packing materials include carbon steel and stainless steel. Because of its thin processing wall, large void ratio, large flux, low resistance, and heat-resistant, corrosion-resistant, separation efficiency and other characteristics, especially suitable for vacuum distillation tower, dealing with heat-sensitive, easy to decompose, easy to polymerize, easy to carbonize the material, which is widely used in petrochemical, chemical fertilizer, environmental protection and other industries in the packing tower.
Metal bulk packing has *** yoke ring, eight four internal arc ring, rectangular saddle ring, double arc ring, flat ring, ladder ring and Bauer ring, Interlocks and so on.
There are many types of tower equipment, tower equipment is one of the most important equipment in chemical, petrochemical and refinery production. It can make gas-liquid or liquid-liquid two-phase close contact between the two phases, to achieve the purpose of interphase mass transfer and heat transfer. Common unit operations that can be accomplished in tower equipment are: distillation, absorption, desorption and extraction. In addition, the cooling and recovery of industrial gases, gas wet purification and drying, as well as both gas-liquid two-phase mass transfer and heat transfer increase
