Abstract
A kind of annular ring wave-shaped filler, it is circular-arc it is characterized in that perforated plate corrugated, and has one group of ring plate on described every section ripple, the ring plate on per two adjacent wave lines is staggered.
Description
The present invention relates to a kind of novel structured packing.Especially a kind of annular ring wave-shaped filler.
At present, widely used in the world perforated plate corrugated filler is garden plate-like (referring to a Russian Patent 1301470).Every dish filler assembles by being pressed into undulatory thin slice, the axis of ripple direction and tower angled (being called the inclination angle).The ripple direction of adjacent corrugated plate is opposite.The inner inclinations that form many mutual intersection symmetries of filler are led to like this.Adjacent packing box fits tightly mutually, and becomes 90 ° of staggered being installed in the tower body mutually.
Fig. 1 is the ripple schematic diagram of corrugated plate in the prior art.δ is the dihedral angle between corrugated surface and the horizontal plane among the figure, and β is the angle of drop flow trace and ripple rib on corrugated surface.ψ is the ripple inclination angle, and ζ is the inclination angle between the adjacent corrugations inclined-plane.Corrugated plate can be woven wire or calendering plate, and its material also can be plastics or pottery.Fig. 2 is to be the geometry of corrugated plate on the normal section vertical with the ripple direction in the prior art.T is a sheet thickness, and h is a crest height.Crest is apart from representing with 2B, and it is by the drift angle ζ decision of peak height and adjacent corrugations face, and drift angle is generally 78～90 °, and every dish packed height H is generally 160 to 300mm with pattern and tower diameter and different.Perforated plate corrugated filler is used widely in commercial plant as the tower packing of function admirable, but owing to himself more structural weakness, following weak point is arranged still:
1. the ripple drift angle is 78～90 ° angle, and liquid is easy to gather herein, influences the gas-liquid contact, reduces mass-transfer efficiency, and the ripple rib has also increased flow resistance simultaneously.
2. tetragonal geometry passages causes the specific area of filler less.
Purpose of the present invention is exactly the above-mentioned weakness at perforated plate corrugated, under the prerequisite that keeps structured packing garden disk-shaped structure, provides a kind of wave forms sheet-garden (or ellipse garden) corrugated sheet to replace perforated plate corrugated, thereby a kind of new annular ring wave-shaped filler is provided.
The object of the present invention is achieved like this: annular ring wave-shaped filler of the present invention can adopt common used materials such as metal, plastics, pottery.For sheet metal, through perforating by punching, be squeezed into waveform, strike out easy steps such as ring-type, promptly can be made into the orifice ring wave plate.Then the staggered bonding of orifice ring wave plate is made packing box together, staggered 90 ° are installed in the tower body.
Because the superior structural of annular ring wave-shaped filler, the present invention has the following advantages:
1. whole wave plate is more level and smooth, and no corner angle help liquid and evenly distribute, and have improved vapour-liquid mass, and then have improved mass-transfer efficiency, simultaneously, has also reduced flow resistance.
2. because the symmetry of its structure, almost there is not an enlarge-effect as long as tower internals is reasonable in design.
3. compare with existing perforated plate corrugated filler, under voidage condition much at one, specific area has increased 10～15%.
4. make annular mass transfer unit regularly arranged, eliminated the contact phenomena on granular filler surface substantially, contact point seldom is a contact, thereby has improved the utilization rate of filler specific surface, has improved mass-transfer efficiency.
5. by above-mentioned analysis, filler of the present invention is compared with perforated plate corrugated filler, can improve mass-transfer efficiency about 15%.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof, and Fig. 1 is the ripple schematic diagram of corrugated plate in the prior art.
Fig. 2 is the geometry schematic diagram of prior art corrugated plate.
Fig. 3 is the geometry schematic diagram of corrugated plate on the normal section vertical with the ripple direction of the annular ring wave-shaped filler that proposes according to the present invention.
Fig. 4 is the schematic diagram of the orifice ring corrugated plate filler of a kind of structure of the present invention.
Fig. 5 is the schematic diagram of the annular ring wave-shaped filler of another kind of structure of the present invention.
Describe the details and the working condition of the concrete device that proposes according to the present invention in detail below in conjunction with accompanying drawing.
Filler of the present invention is discoid, and every dish filler assembles by being pressed into undulatory thin ring plate.Ripple direction and tower axis at an angle, the ripple direction of adjacent wave ring plate is opposite.Adjacent packing box fits tightly mutually, and is mutually 90 ° of staggered being installed in the tower body.
As shown in Figure 3, A, B are respectively half gardens (ellipse garden) of symmetry, and h is a crest height of wave, equals the diameter D in half garden, and crest is apart from being 2D, and t is a sheet thickness.Because change the ripple corner angle into the garden ring-type, thereby can two and half gardens (or ellipse garden) section be processed into symmetrical various rings, saddle ring as shown in Figure 4 etc. also can punch percent opening about 10% on two symmetrical wave bands of A.B.Linkage section C between adjacent two rings can perforate (as shown in Figure 5), to improve the mass transfer effect of linkage section.
The present invention utilizes the saddle ring filling-material structure of function admirable, and constitutive character can better structured packing.Shown in Figure 4 and 5, A.B is respectively half garden (or ellipse garden) of symmetry, and C is the linkage section between adjacent two rings, and D is a ring plate, and E is the ring core sheet.Owing to change perforated plate corrugated corner angle into the garden arcuation, perforate on the linkage section C between adjacent two rings simultaneously is to improve the mass transfer effect of linkage section.
Filler of the present invention is easy to processing, can adopt common used materials such as metal, plastics, pottery, for sheet metal, through perforating by punching, is squeezed into waveform, strikes out easy steps such as ring-type, promptly can be made into the orifice ring wave plate.Then the staggered packing box that is bonded to of orifice ring wave plate is installed in the tower body for staggered 90 °.
Because the superior structural of annular ring wave-shaped filler, the present invention has the following advantages:
1. whole wave plate is more level and smooth, and no corner angle are conducive to uniform liquid and distribute, and improve vapour-liquid mass, and then have improved mass-transfer efficiency, have reduced flow resistance.
2. compare with Russian Patent 1301470, the perforate at D ring and C place makes filler have open structure, thereby reduces the gas flow resistance under the prerequisite that guarantees filling intensity, improves disposal ability; Help simultaneously liquid to form eddy current, improve mass-transfer efficiency.
3. compare with existing perforated plate corrugated filler, under the almost identical condition of voidage, specific area has increased about 15%.
4. annular mass transfer unit is regularly arranged, and (contact point seldom is a contact, thereby has improved the utilization rate of filler specific surface basically to eliminate the contact phenomena on granular filler surface.
5. owing to the symmetry of its structure, almost do not have than big effect as long as tower internals is reasonable in design.
6. by above-mentioned analysis, filler of the present invention is compared with perforated plate corrugated filler, can improve mass transfer effect about 15%.
