Stainless steel conjugate ring packing is a new type of packing that has been newly developed. It is processed by continuous extrusion. In terms of structure, in addition to retaining the original arc-shaped airway of the saddle-type packing, it also retains the characteristics of the tongue-shaped window blades on the side wall of the open-hole packing. It absorbs the advantages of the ring and saddle-shaped packings and adopts a conjugate curve fin structure, which is equivalent to cutting the step ring along the longitudinal axis, and then moving one half down to form the entire conjugate ring. Its structure is symmetrical, using a conjugate curve fin structure, with external curling at both ends and a suitable aspect ratio. There are point contacts between the packings or between the packings and the tower wall, and there will be no overlapping, uniform pores, and low resistance. When it is randomly piled, it is arranged in a directional manner, so it has the characteristics of regular packing, which helps the liquid to be evenly distributed on the surface of the packing, thereby improving the mass transfer performance. It has better fluid mechanics and mass transfer performance.

Characteristics of stainless steel conjugated ring packing:

Stainless steel conjugated ring is a newly developed new type of packing. It is equivalent to cutting the step ring in half along the axial direction, and then turning one half 108° to connect it. There is a semi-circular fin in the middle of each semicircular component. The function of the fin is to increase the mass transfer surface area, improve the mass transfer performance, and prevent the overlap between the packing bodies when the packing is bulk. The characteristic of this packing is that the inner ribs are conjugated and have high symmetry. When stacked in the tower, it is very uniform and there will be no overlap along the axial direction. Therefore, the liquid can be evenly distributed on the surface of the packing; the inner ribs of adjacent packings have many contact points with the surface, which strengthens the convergence and dispersion of the rib liquid and promotes the surface renewal of gas-liquid contact. These characteristics make the conjugated ring have the characteristics of small pressure drop, large flux, large operating flexibility, large gas-liquid contact surface area, excellent fluid mechanics and mass transfer performance.

The three points are summarized as follows:

① When stacked in the tower, the axial overlap occurs;

② Its inner rib structure is conjugate, which is very uniform in the tower, so the liquid is evenly distributed on the surface of the packing;

③ The inner ribs of adjacent packings have many points of contact with the surface, which can intensify the gathering and dispersion of the liquid and the surface renewal;

These characteristics make the conjugate ring have little resistance to the fluid, and provide a large surface for gas and liquid contact, thereby improving the fluid mechanics and mass transfer performance of the packing. Therefore, the conjugate ring packing is a packing with large flux, low pressure drop, high mass transfer efficiency and high operating flexibility.

Material of stainless steel conjugate ring packing:

The material of metal conjugate ring can be of various types, such as A3 carbon steel, 1Cr18Ni9Ti, stainless steel 304, 304L, 410, 316, 316L, etc., which can be selected by the user.

Application of stainless steel conjugate ring packing:

Stainless steel conjugate rings are widely used in vacuum distillation towers to treat heat-sensitive, easily decomposed, easily polymerized, and easily carbonized materials. Therefore, it is widely used as packing in packing towers in petrochemical, fertilizer, environmental protection and other industries. Such as: gas washing tower, purification tower (large processing capacity, with dirt system). Used in eucalyptus oil fractionation unit, cyclopentane acid recovery unit, platinum reforming unit solvent oil tower, can improve the economic benefits of the unit.
