Copper Metal Orifice Plate Corrugated Packing

Structured Packing is a kind of packing arranged and stacked in accordance with uiform geometry in the tower.The geometry of the whole tower section is regular,symmetrical and uniform, and the gas-liquid flow path is specified ,which reduces the phenomeneon of channel flow and wall flow, and the pressure drop can be very small.Under the same energy cost and pressure drop, it can provide more specific suface area than random packing, and achieve higher mass transfer and heat transfer efficiency in the same volume. In recent decades, structured packing has been widely used in many towers in fine chemical industry,perfume industry,oil refining,fertilizer,petrochemical industry and the other fields. Structured packings are available in two different inclination angles,ie. Type X and Type Y. The type Y packings have an inclination and angle of about 45 from the horizontal axis, and are the most widely used.The type X packings have an inclination angle of 30 from horizontal axis and are used in high capacity and low pressure drop applications.

Wire mesh structured packing has a high specific surface area. At the same time, because of the unique capillary effect of the mesh. The packing surface has better wettability. So it has a high separation efficiency. Compared with other types of packing, it has lower pressure drop and less liquid holding, and it is especially suitable for materials hard to separate and heat sensitive systems. The main materials for making wire gauze packing are stainless steel, copper, aluminum, iron, nickel, etc.   

The geometric structure will provide a large specific surface area. The capillary function of the screen also increases the wettability of the surface area. When filling, the upper and lower packing trays cross 90°, which has the advantages of high efficiency, reduced pressure and large flow. It is used in vacuum distillation, atmospheric distillation and the absorption process of difficult to separate or heat sensitive substances.  

It is formed from corrugated sheets of perforated embossed metal or wire gauze. The result is a very open honeycomb structure with inclined flow channels giving a relatively high surface area but with very low resistance to gas flow. The surface enhancements have been chosen to maximize liquid spreading. These characteristics tend to show significant performance benefits in low pressure and low irrigation rate applications. Metal Structured Packing is manufactured in a wide range of sizes by different crimp altitude. The Packing Surface ranges from 50 m²/m³ (lowest efficiency, highest capacity) to 750 m²/m³ ( highest efficiency, lowest capacity ).
