Tapered spiral filling

Abstract

The invention discloses taper spiral stuff. Wherein, the inner side surface of hollow taper has spiral flow groove; the bottom of spiral flow groove has vent holes; and it can be made from variable materials to form integrated or bulk stuffs to apply kinds of industry stuff towers. And said invention can overcome the defects of present industry tower with lower liquid amount, worse operation flexibility, and easy jam. Compared to generate stuff, the operation load is improved 40-60% in same tower pressure; the effective mass transfer area is increased 30-40% in same specific surface area; the mass transfer efficiency is larger; the pressure of stuff layer in unit meter and same spray density is reduced 40-50% generally; and it has stable tower pressure and strong self-washing ability, to apply the operation on high viscous material.

Description

technical field [0001] The present invention relates to packings for industrial packed towers. Background technique [0002] At present, the packing used in industrial packed towers includes bulk packing and structured packing. Bulk packing has the advantages of easy processing, convenient filling, low production cost, and not easy to block; structured packing has large specific surface area, large void ratio, pressure drop, and efficiency. High, small amplification effect, easy to industrialize, etc., but the disadvantages of both are small liquid holding capacity, small operating flexibility, small separation factor, and easy to block. To solve the existing problems, we must first understand its main influencing factors: ① specific surface area and porosity are often a pair of contradictions, if you want to obtain a larger specific surface area, you must increase the number of fillers per unit filling volume, the result It will inevitably reduce the porosity of the packin...

[0002] At present, the packing used in industrial packed towers includes bulk packing and structured packing. Bulk packing has the advantages of easy processing, convenient filling, low production cost, and not easy to block; structured packing has large specific surface area, large void ratio, pressure drop, and efficiency. High, small amplification effect, easy to industrialize, etc., but the disadvantages of both are small liquid holding capacity, small operating flexibility, small separation factor, and easy to block

⑤The gas-liquid two-phases flowing through the packing layer in the tower are in countercurrent contact, so the flow resistance is relatively large; The void ratio of the packing layer will easily lead to liquid flooding in the tower, so the liquid holding capacity is small; ⑦There are a lot of dead angles in the packing layer, the liquid phase flow is disorderly, and the liquid gas is relatively small, so the liquid basically has no self-cleaning effect on the packing surface, so Solid particles are easy to deposit and accumulate on the surface of the filler, which can easily lead to blockage of the filler layer
