◎ ceramic ball: used for covering, supporting, filtering and catalyst support in various packed towers; Heat storage packing of air separation unit; High abrasion resistant grinding medium. Ceramic balls include: inert ceramic balls, open hole ceramic balls, microporous ceramic balls, active ceramic balls, heat storage ceramic balls and grinding ceramic balls.
◎ chemical packing: used for supporting, covering and filtering in drying tower, absorption tower, cooling tower, washing tower and regeneration tower in oil refining, metallurgy, gas, oxygen production and other industries. Chemical packing is divided into ceramic, plastic, metal stacking and regular packing.
◎ ceramic filler: it has excellent acid and heat resistance, and can resist the corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid. It can be used in various high and low temperature occasions, with a wide range of applications. Ceramic packing can be used in drying tower, absorption tower, cooling tower, washing tower, distillation tower, atmospheric tower, synthesis tower, catalytic tower, regeneration tower, etc. in chemical industry, metallurgy, gas, oxygen production and other industries. Ceramic packing is divided into ceramic bulk packing (Rasch ring, Bauer ring, step ring, cross ring, rectangular saddle ring, different saddle ring, conjugate ring, tower internals, Haier ring, wreath, polyhedral hollow ball, covering ball, three y ring, connecting ring, flat ring, etc.) and ceramic corrugated regular packing.
◎ plastic packing has the characteristics of light weight, heat resistance and chemical corrosion resistance, including tower packing made of PP, PE, RPP, PVC, CPVC, PVDF and other materials. Plastic packing has the characteristics of large porosity, low pressure drop and mass transfer unit height, high flooding point, sufficient vapor-liquid contact and high mass transfer efficiency. The service temperature in various media is 60-280 ℃, and plastic packing is widely used in packed towers in petroleum, chemical industry, chlor alkali, gas and environmental protection industries. Plastic packing is divided into plastic bulk packing (polyhedral hollow ball, wreath, Haier ring, stepped ring, Bauer ring, rectangular saddle ring, different saddle ring, conjugate ring, flat ring, rassier ring, snowflake ring, hexagonal ring, rotating ring, pentagonal ring, conical ring, mesh ring, cross spherical ring, floating ball, liquid surface covering ball, diamond covering ball, etc.) and plastic regular packing.
◎ metal packing is tower packing made of carbon steel, stainless steel and composite gold. Metal filler has the advantages of thin wall, cold and heat resistance, large porosity, large flux, low pressure drop, low resistance, good separation effect and long service life. Although the one-time investment is slightly large, it can give full play to the potential power of the equipment. Metal fillers are suitable for vacuum distillation columns to deal with materials that are allergic, easy to decompose, easy to tighten and easy to form carbon. Metal packing is widely used in packed towers in petrochemical, chemical fertilizer, chemical industry, environmental protection and other industries. Metal packing is divided into metal bulk packing (ball ring, rectangular saddle ring, step ring, conjugate ring, 84 inner arc ring, flat ring, etc.) and metal regular packing (metal mesh corrugated packing, metal orifice corrugated packing, calendered perforated plate corrugated packing, metal mesh corrugated packing and HT semi tubular regular packing).
