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

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

(2) Porcelain balls: They are also one of the chemical packings and are used in various packed towers to play the roles of covering, supporting, filtering and catalyst carriers; heat storage fillers in air separation units; high wear-resistant grinding media. Porcelain balls include: inert porcelain balls, open-hole porcelain balls, microporous porcelain balls, active porcelain balls, heat-storage porcelain balls, and grinding porcelain balls.

(3) Ceramic filler: It has excellent acid and heat resistance and can withstand 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 and has a wide range of applications. Ceramic fillers can be used in drying towers, absorption towers, cooling towers, washing towers, distillation towers, atmospheric towers, synthesis towers, catalytic towers, regeneration towers, etc. in chemical, metallurgical, gas, oxygen and other industries. Ceramic packing is divided into ceramic random packing (Raschig ring, Pall ring, step ring, cross ring, moment saddle ring, heterosaddle ring, conjugate ring, Haier ring, rosette, multi-faceted hollow sphere, covered sphere, triple Y ring , ring, flat ring, etc.) and ceramic corrugated structured 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 the characteristics of large void ratio, pressure drop and mass transfer. It has the characteristics of low unit height, high flooding point, sufficient vapor-liquid contact, and high mass transfer efficiency. The operating temperature in various media is 60-280°C. Plastic fillers are widely used in packed towers in petroleum, chemical, chlor-alkali, gas, environmental protection and other industries. Plastic fillers are divided into plastic random fillers (faceted hollow balls, garlands, Haier rings, step rings, Pall rings, rectangular saddle rings, heterosaddle rings, conjugate rings, flat rings, Raschig rings, snowflake rings, hexagonal rings ring, rotating ring, pentagonal ring, conical ring, mesh ring, cross spherical ring, floating ball, liquid surface covering ball, diamond covering ball, etc.) and plastic structured packing.

(5) Metal packing is tower packing made of carbon steel, stainless steel, composite alloy and other materials. Metal packing has the advantages of thin wall, resistance to cold and heat, large void ratio, large flux, low pressure drop, small resistance, good separation effect, long life, etc. Although the one-time investment is slightly larger, it can give full play to the potential of the equipment. Metal packing is suitable for vacuum distillation towers to handle 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, fertilizer, chemical, environmental protection and other industries. Metal packing is divided into metal random packing (Pall ring, saddle ring, stepped ring, conjugate ring, eighty-four inner arc ring, flat ring, etc.) and metal structured packing (metal mesh corrugated packing, metal orifice plate corrugated packing , calendered perforated plate corrugated packing, metal mesh corrugated packing, HT semi-tube structured packing)

Key words:


With strong technical force and complete testing means, the enterprise has passed the ISO9001 quality system certification. All kinds of tower internals, tower and packing products are widely used in oil refining, chemical industry, telephone fee, caustic soda, sulfuric acid, electric power, sewage treatment, coking gas and pharmaceutical industries, and are well received by users.
