Abstract
The utility model discloses peak valley piece-lapping type ripple packing, and belongs to the regular packing for the towers of the fields of chemical industry, etc. The utility model is characterized in that the wave peak and the wave trough of the filler ripple plate sheet are regularly and continuously provided with a valley section and a peak section. The shape of the cross sections of the valley section and the peak section forms a triangle shape. The valley section is composed of two valley surfaces. The upper valley surface is a large trapezoid, and the lower valley surface is a small trapezoid. The peak section is composed of two peak surfaces. The upper peak surface is a large trapezoid, and the lower peak surface is a small trapezoid. Two waist line sections of the trapezoid are the straight lines or the curved lines. The utility model has better fluid mechanics and mass transfer performance, and is widely suitable for the gas and liquid mass transfer fields of chemical engineering, petrochemical industry, pharmacy, fertilizer, etc.
Description
The utility model relates to a kind of peak valley butt strip formula ripple packing.It belongs to employed structured packing in the field towers such as chemical industry.
Existing ripple packing has that pressure drop is lower, the mass-transfer efficiency advantage of higher.Such filler offers the aperture of φ 2～φ 5 in order to improve mass-transfer efficiency on corrugated cardboard sheet, its percent opening is 8～10%, improves the horizontal back-mixing of vapour-liquid between plate with this, thereby reaches the purpose that it improves mass-transfer efficiency.This measure weak point is: the manufacturing process that, has increased filler; Two, the position of opening lack of homogeneity on the plate; Three, wasted material.
The purpose of this utility model is to provide a kind of peak, paddy peak valley butt strip formula ripple packing alternately.This filler has the horizontal back-mixing performance of good vapour-liquid, so its mass-transfer efficiency is higher.
In order to achieve the above object, the utility model is realized by following proposal.With sheet metal or sheet plastic, or other nonmetal thin plate, make the corrugated cardboard sheet that cross sectional shape is continuous isosceles triangle, the inclination angle at the crest line of ripple and filler edge is 10 °～90 °, then corrugated cardboard sheet is assembled into plate-like or blocks, it is characterized in that: on the crest of corrugated cardboard sheet, rule is offered cross sectional shape paddy section triangular in shape discontinuously, two paddy faces that constitute the paddy section are up-small and down-big trapezoidal, trapezoidal two stringcourse sections can be straight line, also can be curve, or the paddy face of formation crest upper valley section is shaped as parallelogram; On the trough of corrugated cardboard sheet, it is leg-of-mutton crest segment that rule is offered cross sectional shape discontinuously, and two peak faces that constitute crest segment are up big and down small trapezoidal, and trapezoidal two stringcourse sections can be straight line, also can be curve, or the peak face of crest segment is shaped as parallelogram on the formation trough.The height of crest segment is less than the 1/2 trough degree of depth, and the degree of depth of paddy section is less than 1/2 crest height.
Fig. 1 is the schematic perspective view of peak valley butt strip formula ripple packing;
Fig. 2 is the vertical view of peak valley butt strip formula ripple packing;
Fig. 3 is that A among Fig. 2 is to view.
In above-mentioned figure, (1) is crest, and (2) are the paddy section on the crest, and (3) are the paddy face of paddy section, and (4) are trough, and (5) are the crest segment on the trough, and (6) are the peak face of crest segment.
Below in conjunction with accompanying drawing the utility model is elaborated.The utility model is to adopt corresponding mould to form through stamped.On the crest (1) of corrugated cardboard sheet, rule is offered cross sectional shape paddy section (2) triangular in shape discontinuously, and two the paddy faces (3) that constitute the paddy section are up-small and down-big trapezoidal, and trapezoidal two stringcourse sections can be straight line, also can be curve, each paddy section and crest constitute two four-sided openings.On the trough (4) of corrugated cardboard sheet, it is leg-of-mutton crest segment (5) that rule is offered cross sectional shape discontinuously, and two the peak faces (6) that constitute crest segment are up big and down small trapezoidal, and trapezoidal two stringcourse sections can be straight line, also can be curve, each crest segment and trough constitute two four-sided openings.Therefore on the ripple of former one-period, form peak, paddy peak valley butt strip formula ripple alternately, the four-sided openings that its each crest, trough constitute with paddy section, crest segment has respectively replaced the punching of former ripple packing, this opening is arranged regular, be evenly distributed, therefore the horizontal back-mixing of vapour-liquid is very even between plate and plate, and mass-transfer efficiency is higher.
The utility model is compared with existing ripple packing has that manufacturing process is simple, mass-transfer efficiency is high, save raw-material characteristics.
Claims (2)
1. peak valley butt strip formula ripple packing, it is to adopt sheet metal or sheet plastic, or other nonmetal thin plate, make the corrugated cardboard sheet that cross sectional shape is continuous isosceles triangle, the inclination angle at ripple crest line and filler edge is 10 °～90 °, then corrugated cardboard sheet is assembled into plate-like or blocks, it is characterized in that: on the crest of corrugated cardboard sheet, rule is offered cross sectional shape paddy section triangular in shape discontinuously, two paddy faces that constitute the paddy section are up-small and down-big trapezoidal, trapezoidal two stringcourse sections can be straight line, also can be curve, or the paddy face of formation crest upper valley section is shaped as parallelogram; On the trough of corrugated cardboard sheet, it is leg-of-mutton crest segment that rule is offered cross sectional shape discontinuously, and two peak faces that constitute crest segment are up big and down small trapezoidal, and trapezoidal two stringcourse sections can be straight line, also can be curve, or the peak face of crest segment is shaped as parallelogram on the formation trough.
2. by the said peak valley butt strip of claim 1 formula ripple packing, it is characterized in that: the height of crest segment is less than the 1/2 trough degree of depth, and the degree of depth of paddy section is less than 1/2 crest height.
