2.5Y Metal Corrugated Plate Structured Packing in Distillation Tower
1. Hualai metal corrugated plate structured packing inspection:
1 Each batch of structured packing shall be inspected by the quality inspection department according to the contract before leaving the factory.
2 The appearance of packing plate shall be flat and free of rust.
3 The peak height, wave distance, inclination and tooth angle of the packing shall meet the corresponding standards.
The deviation between the accumulated length of the peak height of every 100 pieces and the accumulated length of the actual product 100 pieces is: the positive deviation is not more than 1h, and the negative deviation is not more than 2h.
4 The diameter, Ovality and levelness of packing disc shall meet corresponding requirements.
5 For the hole diameter d0, hole center distance t and fine grain on the plate, only visual inspection shall be conducted, and the hole shall be free of burr, and the holes and fine grain shall be evenly distributed.
6 the allowable deviation of steel strip thickness shall comply with the provisions of GB / T 4239.
2. Structural dimension and characteristic parameters of stainless steel orifice corrugated packing.

3. Classification of Hualai metal corrugated plate 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.
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.
