Corrugated metal wire mesh packing consists of vertically arranged corrugated wire mesh strips to form a disk-shaped regular packing, each disk of packing is 40-300mm high, the corrugated direction and the tower axis inclination angle of 30 ° or 45% of the neighboring two pieces of the corrugated direction of the opposite direction, the diameter of the packing disk than the tower diameter of a few millimeters smaller than the tower, depending on the diameter of the tower, the packing disk precision filled with the tower cross-section. Each disk packing outside the hoop can have flange to prevent wall flow, up and down the two neighboring disk rotation 90 ° filling. For small tower diameter, packing the whole disk filling, diameter of 1.5m above the tower or can not Lan structure of the tower, can be used in the form of sub-pieces from the manhole installed in the tower and then assembled. Made of wire mesh corrugated packing of the main materials are stainless steel, copper, aluminum, iron, nickel and so on.

Wire mesh corrugated packing mass transfer performance is directly determined by the specific surface area of the packing. According to the different specific surface area, Jinlian wire mesh packing can be divided into 250, 500, 700 type. As the metal wire mesh packing belongs to the liquid film mass transfer type, in the corrugated packing sheet on the open hole or made of double-layer wire mesh packing to strengthen the liquid in the wire mesh corrugated sheet on the uniform distribution, especially in the low density of spray, whether to ensure that the liquid in the wire mesh sheet uniformly distributed into a film is to maintain a high separation efficiency is the key.

Wire mesh corrugated sheet with small holes to strengthen the liquid distribution and liquid film renewal, reduce the dead space in the packing (especially the small tower), improve the separation efficiency. In order to strengthen the gas-liquid lateral mixing, the corrugated sheet of small holes in the diameter of 4 ~ 5mm is appropriate.

In view of the geometric structure of the wire mesh corrugated packing, the formation of the following characteristics:

1, large specific surface area, high porosity, heavy children light. 500-type filler than the surface area equivalent to Dg50mm metal Bauer ring 4.5 times (Bauer ring specific surface area of 110m2/m3, density of SSOkg/m3), while the density of Bauer ring is only 40%, the porosity is high, the wire mesh has a strong capillary effect so that the wetting performance is excellent, even if the density of the spray for the 0.2m3/( m2 - h), but also the density is very high, and the density is very high, so the density of the spray is 0.2m3/( m2 - h). Even if the spray density is 0.2m3/( m2 - h), it can achieve complete wetting, so the packing efficiency is high.

2、Gas phase pathway inclination angle is small, there are rules of the gas phase pathway, less pressure loss, packing pressure reduction.

3, radial diffusion is good, gas-liquid contact is sufficient.

4, avoid clogging, afraid of corrosion, difficult to clean, can only be cleaned by chemical methods.

5, unit volume packing high cost, so that its scope of use is somewhat limited.
