Plastic step ring packing has flanges added to the side ends of the step ring packing, which not only increases the mechanical strength of the packing ring, but also increases the probability of orientation when the packing is placed because the axial symmetry of the packing structure is destroyed. Due to the influence of the flanges, the contact between the packing ring gaps during packing stacking changes from linear contact to point contact. In this way, not only the gaps between the packing particles are increased, reducing the resistance of the gas passing through the packing layer, but also these contact points can be the convergence and dispersion points of the liquid flowing along the surface of the packing, thereby promoting the surface renewal of the liquid film and improving the mass transfer efficiency of the packing.

Features of plastic step ring packing:

Plastic step ring packing absorbs the characteristics of Raschig rings, and at the same time makes appropriate improvements to ball ring packing. The height-to-diameter ratio of the ring is 1:2, and a conical flange is added at one end to reduce the resistance of the gas passing through the bed layer. The upper opening is a 45-degree bell mouth.

Due to the unique structure of the plastic step ring, it has the characteristics of large general volume, small pressure drop, high mass transfer efficiency, large load elasticity, good anti-fouling, high cooling efficiency, high filler strength, uniform gas-liquid distribution, high gas-liquid contact area, small resistance, flame retardant, strong load and ice resistance, low minimum spray density, and long life.

Application of plastic step ring filler:

Plastic step ring filler has excellent acid and heat resistance, and can resist corrosion from various inorganic acids, organic acids and organic solvents except hydrofluoric acid. It can be used in various high-temperature occasions and can work and use at pressures as low as 0.1 mmHg. The application range is very wide. It can be used in drying towers, absorption towers, cooling towers, washing towers, regeneration towers, and reaction towers in chemical, petroleum, chlor-alkali, metallurgy, coal gas, environmental protection and other industries.

Actual case:

It can be actually applied to carbon dioxide degassing towers, ozone contact reaction towers, acid mist purification towers, decarbonization and desulfurization systems of synthetic ammonia plants, various separations of crude oil separation and atmospheric pressure reduction devices, methanol separation, organic acid separation, etc.
