What is the purpose of chemical fillers? The detailed introduction of chemical packing manufacturers is as follows:


(1) Chemical packing: used in drying towers, absorption towers, cooling towers, washing towers, and regeneration towers in oil refining, metallurgy, gas, and oxygen production industries to support, cover and filter. Chemical packing is divided into ceramics, plastics, Stacked metal material and structured packing.


(2) Porcelain ball: it is also a kind of chemical packing used for covering, supporting, filtering and catalyst carrier in various packing towers; heat storage packing for air separation unit; high wear-resistant grinding media. Ceramic balls include: inert ceramic balls, open-pored ceramic balls, microporous ceramic balls, active ceramic balls, heat storage ceramic balls, and grinding ceramic balls.


(3) Ceramic filler: It has excellent acid and heat resistance, can withstand the corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, can be used in various high and low temperature occasions, and has a wide range of applications. Ceramic packing can be used in drying towers, absorption towers, cooling towers, washing towers, distillation towers, atmospheric towers, synthesis towers, catalytic towers, regeneration towers, etc. in the chemical, metallurgical, gas, and oxygen production industries. Ceramic packing is divided into ceramic random packing (Raschig ring, Pall ring, step ring, cross ring, rectangular saddle ring, different saddle ring, conjugate ring, Haier ring, rosette, multi-faceted hollow ball, covering ball, three Y ring , Continuous ring, flat ring, etc.) and ceramic corrugated structured packing.

Chemical packing

(4) Plastic packing has the characteristics of light weight, heat resistance, chemical corrosion resistance, etc., including tower packing made of PP, PE, RPP, PVC, CPVC, PVDF and other materials. Plastic packing has large porosity, pressure drop and mass transfer The unit height is low, the flood point is high, the vapor-liquid contact is sufficient, and the mass transfer efficiency is high. The operating temperature in various media is 60-280°C. Plastic packing is widely used in packing towers in petroleum, chemical, chlor-alkali, gas, and environmental protection industries. Plastic packing is divided into plastic random packing (multi-faceted hollow ball, rosette, Haier ring, step ring, Pall ring, rectangular saddle ring, different saddle ring, conjugate ring, flat ring, Raschig ring, snow ring, hexagonal ring Ring, rotating ring, pentagonal ring, conical ring, net ring, cross spherical ring, floating ball, liquid surface covering ball, diamond covering ball, etc.) and plastic structured packing.


(5) Metal packing is a tower packing made of carbon steel, stainless steel and combined gold. Metal filler has the advantages of thin wall, cold and heat resistance, large porosity, large flux, reduced pressure, small resistance, good separation effect, and long life. Although the one-time investment is slightly larger, it can fully exert the potential of the equipment. Metal packing is suitable for vacuum distillation towers to process materials that are allergic, easy to decompose, easy to close, and easy to form carbon. Metal packing is widely used in packing towers in petrochemical, fertilizer, chemical, environmental protection and other industries. Metal packing is divided into metal random packing (Pall ring packing, rectangular saddle ring, step ring, conjugate ring, eight-four inner arc ring, flat ring, etc.) and metal structured packing (wire mesh corrugated packing, metal orifice corrugated Packing, calendered perforated plate corrugated packing, metal mesh plate corrugated packing, HT half-pipe structured packing)
