Metal wire mesh corrugated structured packing is a disc-shaped high-efficiency packing composed of vertically arranged corrugated metal wire mesh sheets, which is an important branch of structured packing. Its core structural features include:

Corrugated design: The inclination angle of the corrugated sheet is 30° or 45°, the two adjacent corrugations are in opposite directions, and the upper and lower plates of fillers are rotated 90° and stacked to form a fluid cross-mixing channel.

Material diversity: The main material is stainless steel (304, 316L, etc.), and some products use copper, aluminum, titanium or duplex steel to adapt to corrosive or high temperature conditions.

Precision processing: The wire mesh sheet is pressed, punctured or perforated to enhance wettability, with a pore size of 0.4-0.5mm, which reduces dead angles and improves separation efficiency.

Corrugated Structured Packing  Performance Advantages

Efficient mass transfer

Large specific surface area: The specific surface area of ​​500 type packing is 500m²/m³, which is 4.5 times that of traditional ball rings, providing more gas-liquid contact surface per unit volume.

Low pressure drop: The gas phase passage has a small inclination angle, and the regular arrangement reduces the pressure loss by 30%-50%, which is especially suitable for vacuum distillation (pressure <7KPa).

Large operating flexibility: There is no low load limit, and the number of theoretical plates increases with the decrease of gas load, which adapts to fluctuating conditions.

Optimized fluid distribution

The corrugated structure forces the air flow direction to change frequently, and the liquid is evenly redistributed, reducing wall flow phenomenon and improving mass transfer efficiency.

The capillary action of the wire mesh ensures that it can still be fully wetted at low spray density (0.2m³/m²·h) to avoid dry areas.

Energy saving and capacity expansion

The flux is large, and the new tower design can reduce the diameter by 20%-30%; the transformation of the old tower can increase the processing capacity by more than 50%.

The pressure drop is reduced, the energy consumption of the compressor is reduced, and the long-term operating cost advantage is significant.
