0.15mm Metal Plate 125Y Structured Packing In Tail Gas Treatment

Product Specification

0.15mm metal plate 125Y structured packing in tail gas treatment

1. Classification of structured packing

Packed tower is a kind of gas-liquid mass transfer equipment with a large number of packings in the tower. Packed column was used in industrial production in the middle of the 19th century. Since then, it has developed with plate column, forming two different types of gas-liquid mass transfer equipment. 

2. The structure of packed tower using structured packing

The body of the packed tower is a vertical cylinder with a supporting plate at the bottom. The packing material is placed on the support plate in a integral way. A packing pressing plate is installed above the packing to limit the movement of the packing with the updraft. The liquid is added from the top of the tower, sprayed onto the packing through the liquid distributor, and flows down the packing surface. The gas is sent from the bottom of the tower and distributed by the gas distribution device (gas distribution device is generally not set for small diameter tower), then it is countercurrent with the liquid and continuously passes through the gap of the packing layer. The gas-liquid two-phase is in close contact with the packing surface for mass transfer. Packed tower is a continuous contact gas-liquid mass transfer equipment, the two-phase composition changes continuously along the tower height. Under normal operation, the gas phase is continuous phase and the liquid phase is dispersed phase.

5. HG/T 21559.2—2005— structured packing standard

Standard No. - year No. - packing model - inner diameter of tower Φ (mm)

For example, the inner diameter of packing tower is Φ 600mm, and p250i type stainless steel orifice corrugated packing is used, which is marked as follows: HG/T 21559.2—2005—P250I—600.

3.2 Specifications and characteristics

3.2.1 Stainless steel orifice corrugated packing is a number of corrugated plates pressed from stainless steel strip, which are vertically stacked and assembled into a disc-shaped structured packing according to the requirements of a certain diameter. The corrugations of the adjacent corrugated plates are inclined in the opposite direction, and the corrugations of the upper and lower adjacent packing plates are 90 ° crossed.

3.2.2 Before the corrugated plate is pressed, it is necessary to punch holes on the plate in advance and press the fine grain, or use the rolling grain equivalent to the fine grain.

3.2.3 Eight types of stainless steel orifice plate corrugated packing are listed in the table. The characteristic parameters of the type selection are the specific surface area of the packing and the angle of the corrugation, which can be selected according to the process design requirements.
