PP ladder ring

1、 Product Introduction

The materials of plastic ladder rings includePP, PE, PP, PVC, CPVC, PVDF and other materials were invented by MTL company in the UK, so they are also known as CMR. Compared to traditional fillers, polypropylene stepped rings have the characteristics of high flux, reduced pressure, and wide operating elasticity range. Its anti fouling performance is significant, which can effectively reduce material blockage and extend equipment maintenance cycle. Typical cases show that using this packing can reduce the pressure drop of the tower to 30% of traditional packing. This product complies with the standards of the Ministry of Chemical Industry and is mainly made of polypropylene. Different specifications and models correspond to specific specific specific surface area and porosity parameters.

2、 Characteristics

PP ladder ringThe side end of the filler has been added with a flange, which not only increases the mechanical strength of the filler ring, but also increases the directional probability of the filler when it is placed due to the fact that the plastic stepped ring filler has destroyed the symmetry of the filler structure. Due to the influence of flanging, the contact between the gaps of the stepped ring packing during stacking changes from linear contact to point contact.

Product Features

PP ladder ringfillerNot only does it increase the gaps between the packing particles and reduce the resistance of gas passing through the packing layer, but these contact points can also serve as gathering and dispersing points for the liquid flowing along the packing surface, thereby promoting the surface renewal of the liquid film and improving the mass transfer efficiency of the packing.So the plastic ladder ring has reduced pressure, high flux, high efficiency, large load elasticity, and good pollution resistance. There are various sizes of plastic step ring fillers, commonly includingDiameter 25mm, diameter 38mm, diameter 50mm, diameter 76mm, etc. Different sizes are suitable for different tower diameters and process requirements. Generally speaking, when the tower diameter is large, larger sized packing materials can be used to reduce the number of packing layers and pressure drop; Small towers are suitable for small-sized packing materials, which can increase the specific surface area and improve mass transfer efficiency.

Scope of application

Plastic step rings are used in various separation processes such as decarbonization, desulfurization systems, and crude oil separation atmospheric and vacuum distillation units in synthetic ammonia plants, such as methanol separation, organic acid separation, and absorption and desorption towers.
