Geometrical characteristics of double-layer wire mesh corrugated packing

There are two types of corrugated packing: wire mesh corrugated packing and plate corrugated packing. Wire mesh corrugated packing is further divided into metal wire mesh and plastic wire mesh. They are all disc-shaped regular packings composed of vertically arranged corrugated mesh strips. The corrugations of two adjacent pieces are in opposite directions and are separated by a certain distance on the corrugated sheet. The main materials are stainless steel, copper, aluminum, monel, iron, nickel, plastic, etc. The following editor will introduce you to double-layer wire mesh corrugated packing, which means adding another layer of wire mesh on the basis of single-layer wire mesh.

The geometric structure characteristics of the double-layer wire mesh corrugated packing: The double-layer wire mesh corrugated packing has basically the same geometric structure as the single-layer wire mesh corrugated packing. It is a disc-shaped regular packing composed of corrugated mesh sheets arranged parallel to each other and vertically. It is made of double-layer 80-100 mesh stainless steel wire mesh overlapped and rolled into corrugated sheets. It is believed that the corrugation directions of the corrugated sheets are opposite, and it is made into a cylinder of a certain height. After decontamination treatment, the adjacent two discs are staggered 90 degrees and loaded into the tower.

The scope of application of double-layer wire mesh corrugated packing: Double-layer wire mesh corrugated packing is developed for the poor wetting performance of stainless steel to certain systems and the immature surface treatment strengthening technology. Therefore, for some towers with special requirements, although the material used is doubled compared to the single-layer, the separation efficiency is doubled. For example, the reactor dilution heavy water re-enrichment device must improve the separation efficiency and reduce the tower height and volume. The use of this packing can reduce the height and floor space of the plant. In addition, in the absence of high-mesh wire mesh materials and the need to improve the separation efficiency, the corrugated packing made of double-layer mesh stacking is also very desirable. It has been applied in separation in China and achieved good results.

The thickness of the corrugated mesh or plate is mainly determined by the strength of the material and the rigidity of the molded packing. Generally speaking, the thickness is as thin as possible, so that the pressure drop is small, the flux is large, the material is saved, and the weight is light. Depending on the material, the thickness of the corrugated packing mesh or plate is usually between 0.1-1.5mm.
