Abstract

The utility model relates to corrugated structured packing with edge holes, and belongs to the technical field of gas-liquid mass transfer equipment in the oil refining industry, the petrochemical industry and the chemical industry. The structured packing is formed by parallel corrugated plates which are laminated; the directions of the crests of every two adjacent corrugated plates are opposite, and the corrugated plates are laminated to form the structured packing; small holes are formed in the surfaces of the corrugated plates; and one or two rows of edge holes are formed at the two ends of each corrugated plate. The structured packing provided by the utility model reduces the wave vertex angles and wave pitches of the corrugated plates, so as to reduce the friction and collision of crosscurrents between every two adjacent corrugated plates, decrease the pressure drop, improve the treatment capacity of a tower and prevent liquid from forming channels at the troughs; and the gas holes at the two ends of the corrugated plates enable gas to flow in multiple directions at the joint of every two vertically-adjacent corrugated plates, so as to greatly reduce the local resistance at the joint, and effectively avoid local flooding.

Description

The corrugated regular filler that a kind of edge is with holes

Technical field

The utility model relates to a kind of edge corrugated regular filler with holes, belongs to gas-liquid contact mass transfer equipment technical field in oil refining, petrochemical industry and the chemical industry.

Background technology

At present, the metal structured packing of extensive use in oil refining, petrochemical industry and the chemical industry is a perforated plate corrugated filler, as Mellapek filler etc.It is made up of some metal corrugated plates that are parallel to each other, and the ripple section is a zigzag, and the ripple drift angle is about 75～90 °, the pitch of waves is about 2 times of crest height, and the ripple inclination angle is 45 ° or 60 °, and the crest direction of adjacent corrugated plate becomes opposed alignment, during installation, two layers of filler half-twist are stacked up and down.

Though such filler of prior art has good performance, as will further improve production capacity, still have then that pressure drop is higher, the shortcoming of easy liquid flooding.There are two problems specifically:

The one, about 90 ° of ripple drift angle, the pitch of waves is about 2 times of crests.This configuration makes two strands of air-flows of cross flow one in adjacent two corrugated plating passages form phase mutual friction and collision near contact-making surface, produce violent eddy current loss, thereby the pressure drop that produces is big, and production capacity is not high.

The 2nd, the edge on the adjacent two layers corrugated plating is interlaced, and fluid forms zig zag when flowing through two-layer filler intersection, thereby causes bad flowing, and then causes the generation of local liquid flooding.

Summary of the invention

The purpose of this utility model is to propose a kind of edge corrugated regular filler with holes, changes the structure and the shape of prior art, with further reduction pressure drop, improves the production capacity of structured packing, prevents the generation of channel and local liquid flooding.

The corrugated regular filler that the edge that the utility model proposes is with holes, be formed by stacking by the corrugated plating that is parallel to each other, the crest direction of adjacent two corrugated platings is opposite, superimposed and form structured packing, on, the angle of two dish corrugated platings is 45 °～90 ° down, the crest of each corrugated plating and trough and plate length direction constitute the ripple inclination angle, the ripple angle of inclination beta is 45 °～60 °, the ripple drift angle is α=45 °～75 °, peak height h=5～30mm, the corrugated plating surface is with holes, and the diameter of aperture is 4～5mm, the corrugated plating two ends have single or double edge hole, and the diameter of edge hole is 6～15mm.

The corrugated regular filler that the edge that the utility model proposes is with holes, compared with the prior art, the wave crest angle and the pitch of waves of corrugated plating have been reduced, this structure can reduce the friction and the collision of crosscurrent between adjacent two corrugated platings, thereby reduce the packing layer resistance, reduce pressure drop, make corresponding being improved of disposal ability of tower, simultaneously, the ripple drift angle reduces also can avoid forming at the trough place channel; Two ends at corrugated plating have pore, gas is flowed to a plurality of directions when flowing through the intersection of two dish corrugated platings up and down, and needn't can reduce local resistance herein so greatly, thereby effectively contain the generation of local liquid flooding according to original racing flow passage.

The specific embodiment

The corrugated regular filler that the edge that the utility model proposes is with holes, be formed by stacking by the corrugated plating that is parallel to each other, the crest direction of adjacent two corrugated platings is opposite, superimposed and form structured packing, on, the angle of two dish corrugated platings is 45 °～90 ° down, as shown in Figure 1, the crest 2 of each corrugated plating 1 and trough 3 constitute the ripple angle of inclination beta with the plate length direction, and the ripple angle of inclination beta is 45 °～60 °, as shown in Figure 2, it is characterized in that the ripple drift angle is α=45 °～75 °, peak height h=5～30mm, corrugated plating 1 surface is with holes 4, the diameter of aperture is 4～5mm, and the corrugated plating two ends have single or double edge hole 5, and the diameter of edge hole 5 is 6～15mm.

Below in conjunction with accompanying drawing, the characteristics and the operation principle of the corrugated regular filler that the edge that detailed description the utility model proposes is with holes:

Corrugated regular filler of the present utility model has reduced the wave crest angle and the pitch of waves of corrugated plating, and has pore at the two ends of corrugated plating.When gas flows in the passage of filler, when resistance mainly comes on-way resistance due to the self-friction and gas to flow through two-layer filler transition region because of changing the local resistance due to the direction, on-way resistance main with the two strands of crosscurrents in adjacent two corrugated plating interface places friction, collide relevant; Interlaced on the two dish corrugated platings up and down, when gas is flowed through herein, can form zig zag at this intersection, cause local resistance to increase sharply, form local liquid flooding.Reduce the wave crest angle and the pitch of waves of corrugated plating, can reduce the friction and the collision of crosscurrent between adjacent two corrugated platings, thereby reduce the packing layer resistance, reduce pressure drop, make corresponding being improved of disposal ability of tower, simultaneously, the reducing of ripple drift angle also can avoid forming at the trough place channel; Two ends at corrugated plating have pore, gas is flowed to a plurality of directions when flowing through the intersection of two dish corrugated platings up and down, and needn't can reduce local resistance herein so greatly, thereby effectively contain the generation of local liquid flooding according to original racing flow passage.
