Window and hole combined flow guide regular filler sheet and filler

Abstract

The invention relates to a window and hole combined flow guide regular filler sheet and a filler. The crest and trough of a corrugated filler sheet are provided with a hole and a window which are communicated to form a window and hole combined structure; an inclination angle is formed between the ripple direction of the corrugated filler sheet and the vertical direction; a regular filler consists of the window and hole combined flow guide regular filler sheets which are parallel to one another and of which the ripple directions are arranged in a staggered mode; and when the tower diameter is larger, a plurality of regular fillers are arranged, and corrugated sheets of the fillers on an upper tray and a lower tray rotate by 15 to 90 degrees. Under the action of fluid velocity and gravity, flowing liquid can be more effectively aggregated due to a hole structure; and a window structure connected with the hole structure is just positioned below the hole structure, so that the liquid flowing down is guided to the crest position on the other side of the filler sheet, the turbulent degree of a gas-liquid phase liquid film between adjacent window bodies is increased, pressure drop is reduced, gas-liquid flux is increased, and the updating of the liquid film and the increase of gas-liquid mass transfer area are more effectively realized.

Description

technical field [0001] The invention relates to a window and hole combined diversion structured packing used in gas-liquid mass transfer processes such as rectification and absorption, in particular to a new type of structured packing that can effectively accelerate liquid film renewal and turbulence. Background technique [0002] Structured packing is a kind of packing that is neatly stacked according to uniform geometric patterns in the tower. This kind of packing artificially defines the gas and liquid flow paths in the packing layer, which reduces the phenomenon of channel flow and wall flow, and greatly reduces the The pressure drop improves the effect of heat and mass transfer. At present, the more classic structured packing is mostly metal plate corrugated structured packing. When this packing is used for gas-liquid mass transfer operations such as rectification or absorption, the gas-liquid two phases in the packing are generally countercurrent contact mass transfer ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a more efficient liquid film diversion structured packing, to improve the structure of the window diversion structured packing and the traditional plate corrugated packing, and to improve the structure of the window diversion structured packing in the liquid film flow process. Due to the influence of surface tension, viscosity and other factors, the diversion window may be sealed, and the liquid cannot be diverted to the other side of the packing sheet, which hinders the realization of liquid film renewal and affects the gas-liquid mass transfer rate. , a further development
