Metal Perforated Plate Corrugated Packing

Metal Perforated Plate Corrugated Packing is made from perforated plate with channel corrugation on surface, and remains structure feature of metal wire gauze packing. It strengthens uniform liquid distribution and surface wetting ability, which increases mass transfer efficiency. The unit height is 50-200mm per coil, and the packing is prepared in blocks when diameter is larger than 1.5m.

It is formed from vertical sheets of corrugated metal with the angle of the corrugation reversed in adjacent sheets to form an open structure with inclined flow channel. Its structure can not only change the distribution of liquid, but also increase the transfer efficiency.

Product characteristics:

It has characteristics such as small resistance, even gas and liquid distribution, high efficiency, large flow rate and unremarkable magnifying effects etc. It\'s applied to negative pressure, normal pressure and pressurization operation.

Application fields:

The packing has advantages such as high capacity, low resistance, high mass-transfer efficiency and strong resistance to fouling. It is widely used in unit operations like rectification, absorption and extraction. According to packing types, the applicable minimal tower diameter is 80-200mm while maximal tower diameter reaches 13m, liquid spray density ranges from 0.2 to 200m3/(m2?h) and pressure ranges from vacuum to high pressure. For these reasons it is a type of all-purpose efficient structured packing suitable for chemical industry, chemical fertilizer industry, oil refining, petrochemical industry and natural gas industry, etc.
