CY700 stainless steel wire mesh corrugated packing

CY700 stainless steel wire mesh corrugated packingLike plate corrugated packing, the disc-shaped regular packing is composed of vertically arranged corrugated wire mesh strips. The direction of the corrugations is inclined at 30 or 45 degrees to the tower axis, and adjacent two corrugations have opposite directions. The diameter of the packing disc is several millimeters smaller than the tower diameter, tightly filling the tower section. The outer hoop of each packing plate can have a flange to prevent wall flow, and the adjacent upper and lower plates can be rotated 90 degrees for loading. For small towers with a diameter of over 1.5m or towers without flange structures, the filling material can be packed in a whole tray. For large towers with a diameter of over 1.5m or towers without flange structures, they can be assembled in blocks by being loaded into the tower through manholes. The main materials used to make wire mesh corrugated packing include stainless steel, copper, aluminum, iron, nickel, etc. At present, the main specifications of metal wire mesh corrugated packing include 20 types (AX type), 500 types (BX type), and 700 types (CY type). DX type, EX type, small metal wire mesh corrugated packing, and double-layer wire mesh corrugated packing are used for laboratory applications.

CY700 stainless steel wire mesh corrugated packingThere are small holes on the corrugated sheet to enhance liquid distribution and liquid film renewal, reduce dead corners in the packing (especially in small towers), and improve separation efficiency. To enhance the lateral mixing of gas-liquid, it is advisable to have small holes on the corrugated sheet with a diameter of 4-5mm.

Given the geometric structure of corrugated metal wire mesh fillers, the following characteristics are formed:

Firstly, it has a large specific surface area, high porosity, and light weight. The specific surface area of the 500 type filler is equivalent to 4.5 times that of the DN50 metal ball, while the density is only 40% of the ball ring. The high porosity and strong capillary action of the wire mesh make it excellent in wetting performance. Even with a spray density of 0.2m3/(m2 · h), it can achieve full coverageWetting results in high filler efficiency.

Secondly, the gas phase pathway has a small inclination angle, a regular gas phase pathway, less pressure loss, and reduced packing pressure.

Thirdly, good radial diffusion ensures sufficient gas-liquid contact.

Fourthly, avoid blockage, corrosion, and difficulty in cleaning, and only use chemical methods for cleaning.

Fifth, the high cost of unit volume fillers limits their range of use to a certain extent.

Metal wire mesh corrugated packing is a type of metal regular corrugated packing, also known as corrugated wire mesh packing. This regular corrugated packing is also a type of distillation tower wire mesh packing, which we call stainless steel wire mesh corrugated packing, also known as metal wire mesh corrugated packing or stainless steel corrugated packing. The two common models are BX500 metal wire mesh corrugated packing and CY700 regular packing.

The corrugated wire mesh packing produced by Shanghai Environmental Protection New Materials Co., Ltd., also known as stainless steel wire mesh corrugated packing, is a wire mesh regular corrugated packing made of stainless steel material. Stainless steel wire mesh corrugated packing was also a widely used high-efficiency packing material in various countries around the world at that time. The commonly used stainless steel wire mesh standards for wire mesh corrugated packing are: 60 mesh stainless steel wire mesh with wire diameters of 0.15mm and 0.12mm.
