Metal perforated plate corrugated packing
Metal perforated plate corrugated packing
LiandaFiltration metal porous plate corrugated packing is a high-performance mass transfer element widely used in various tower equipment. It is made of punched stainless steel sheets, which are stacked after precision corrugation to form regularly arranged gas-liquid contact channels. This product has the characteristics of high separation efficiency, low pressure drop, and resistance to fouling and clogging. It is an ideal structured tower packing in separation processes such as distillation, absorption, and desorption.
Compared with traditional packing, the perforated plate structured packing design adopted by this product not only improves the operational stability, but also significantly improves the mass transfer efficiency per unit volume. Its robust structure and modular design are suitable for large towers or revamp projects, allowing for quick installation and maintenance.
High-efficiency perforated plate corrugated structured packing, various surface treatment methods, widely used
Metal perforated plate corrugated packing is a structured packing with the advantages of large theoretical plate number, high flux, low pressure drop and low load. It is made of neatly arranged mesh sheets pressed into a corrugated shape with a corrugation angle of 30° or 45°, and the corrugation directions of two adjacent sheets are opposite. When the packing tower is filled, the metal perforated plate corrugated packing on the two trays is staggered at 90°.
Metal perforated plate corrugated packing is generally used for atmospheric distillation, vacuum distillation and the absorption process of heat-sensitive or difficult-to-separate substances.

Product Features and Benefits
High-efficiency separation performance
The ripple direction is staggered and superimposed, which increases the liquid wetting area and gas-liquid disturbance. It is suitable for precision separation process and is a typical high-efficiency distillation packing.
Low pressure drop energy-saving structure
The large porosity and regular channels ensure that the resistance during operation is extremely low, which is particularly suitable for vacuum towers and is an ideal low pressure drop tower internals.
Corrosion-resistant and high-temperature resistant materials
Corrosion-resistant metals such as 316L and Inconel can be selected, which are suitable for complex environments such as organic solvents, acidic gases, and high-temperature reactions.
Strong anti-clogging ability
The perforated sheet does not hang liquid and is easy to wash. It can maintain a good operating state even in systems containing solid or sticky materials.
Modular and easy-to-assemble design
The use of standardized modules can achieve rapid stacking and assembly, shorten the installation cycle, and facilitate later maintenance and replacement.

FAQ
Wire mesh packing is suitable for high-purity separation but has poor anti-clogging ability; porous plate packing has a stronger structure and a larger flux, and is suitable for scenes containing impurities or with large processing volumes.
According to the relative volatility and processing volume requirements of the separation system, a corrugation angle of 30° is suitable for high separation efficiency occasions, and 45° is suitable for high load scenarios; we can provide CFD simulation and selection recommendations.
Yes. LiandaFiltration can customize the module shape and combination according to tower diameter, support structure and inlet method.
