Description
The present invention relates to the filler that a kind of tower that carries out material and/or heat exchange is used.
Existing this filler is made of lamellar base material usually, and as the gas-liquid contact medium that the tower that carries out material and/or heat exchange is used, is widely used on destilling tower, absorption tower and the recovery tower.In addition, the article that also have the material beyond the lamellar base material that constitutes by this filler to constitute.For example, the filler that constitutes by the alternative lamellar base material of netted base material.This material that is made of netted base material though function admirable costs an arm and a leg, is difficult to be extensive use of.By comparison, what are weaker on the carrier performance that is formed by lamellar base material, but moderate, knownly easily adopt as filler.Therefore, later desired be the serviceability that improves this lamellar base material.
As everyone knows, in order to improve the performance of this filler, just must improve the contacting efficiency of gas-liquid.Various ways have been adopted for this reason.A kind of method wherein is the capacity that increases the per unit volume filler.This increases the capacity of filler in the hope of increasing the method for gas-liquid contact area for passing through.But this method can produce a problem.This problem is that the pressure loss in the time of can causing the gas rising increases so inappropriate situation.For the operation of the tower that carries out material and/or heat exchange, the fact that the increase of the pressure loss can produce bad influence is well-known.In addition, even increase contact area individually,, just can not realize the raising of contacting efficiency if can not on this surface, make gas-liquid reach enough diffusions.
In actual moving process, liquid is compared with gas, because its viscosity, influence such as surface tension is bigger, therefore, do effort to relevant liquid diffusion especially.For this reason, at existing surface side filler, have much by stressing to consider that the diffusion of liquid solves the such problem of efficient raising of filler.
On the public clear 54-15554 communique of spy, put down in writing a kind of method that whole liquid is incorporated in the ditch of offering on the lamellar substrate surface, yet this method is also just considered the diffusion problem of liquid.
In addition, as known filler, having a kind of is that habitat flatly is set on lamellar base material, so that the liquid horizontal proliferation.
In order so to make the liquid lateral magnification, be provided with on the lamellar base material under the situation of habitat or ditch, though, horizontal proliferation to liquid when the degree of depth of the bending of habitat or the degree of depth of ditch are dark is favourable, but, in being placed on filler in the tower, if the words of inclination are arranged in the horizontal direction, liquid will flow along ditch towards lower because of this tilts, and Here it is has caused the reason of bias current.On the device that uses this filler, bias current is to influence one of the most serious problem of performance performance.For preventing this problem, existing filler can only be offered shallow gathering ditch.For this reason, liquid can't be expanded fully.
Require the foregoing liquid that makes to realize diffusion fully for improving the efficient of gas-liquid contact, being not only, also must consider relation, improve mutual flowing Relationship by gas-liquid.
A kind of method wherein of being considered is by forming certain specific shape at lamellar substrate surface, thereby destroys the boundary layer that exists on the gas-liquid two-phase contact interface.Though to improve contacting efficiency be unusual useful means and be the known fact by destroying the boundary layer, on existing filler, design simultaneously realizes that the filler that strengthens liquid diffusion and destruction boundary layer do not see so far.
In the filler design concept of on the public clear 54-15554 communique of spy, putting down in writing, do not consider to destroy the boundary layer.If consider, obviously be not enough with special public clear 54-15554 number method from the diffusion and destruction two aspects, boundary layer of liquid.
In order to overcome the defective that exists in the prior art, the inventor has carried out concentrating on studies extensively and profoundly.Found that, process into the concavo-convex ditch of waveform at lamellar substrate surface, except on this lamellar base material, forming the waveform folding line, also to make this ditch shape that becomes to crawl, simultaneously, rely on the jog of chase and protruding ditch is mounted to relation corresponding to the tower axle, just can positively strengthen the diffusion and the raising gas liquid contacting efficiency of gas-liquid the while.
Promptly, with reference to figure 2 structure of the present invention is described, a first aspect of the present invention is the filler that a kind of tower that carries out material and/or heat exchange is used, the above-below direction of this filler along tower axis is configured in the tower, make from the liquid of top confession and in tower, contact by gas-liquid with the below gas supplied, between two materials, carry out material and/or heat exchange, this packing material is made up of the laminated plate that becomes its Surface Machining of polylith the lamellar base material (2) of a plurality of continuous folding line of the waveform that tilts with respect to tower axis that folding line is reciprocally stacked together, it is characterized in that, on the surface of this lamellar base material, be formed with many and become concavo-convex ditch continuously along extending transversely, at least the upper side of the downside of chase or the protruding ditch shape that becomes to crawl, when the state that filler is arranged in the tower, be positioned at
The chase bottom surface (7) of the top position at the top (5) of the protruding ditch protuberance of lamellar base material, compared with the raised face (RF) (8) of the protruding ditch of the lower position of relevant protruding ditch the lowest point (6), the top position that is in the tower axle forms.
In addition, be the filler that a kind of tower that carries out material and/or heat exchange is used according to a second aspect of the invention, the above-below direction of this filler along tower axis is configured in the tower, make from the liquid of top confession and in tower, contact by gas-liquid with the below gas supplied, between two materials, carry out material and/or heat exchange, this filler is by its Surface Machining of polylith is become the lamellar base material (2) of a plurality of continuous folding line of the waveform that tilts with respect to tower axis the folding line laminated plate that stacks together is formed interlacedly, it is characterized in that on the surface of this lamellar base material, being formed with the concavo-convex snakelike shape of a plurality of continuous one-tenth along the ditch that laterally stretches, the spacing of crawling between the adjacent chase or between the protruding ditch staggers mutually, under the state that packing material is arranged in the tower, the chase bottom surface (7) of the upper section at the top (5) of the protruding ditch protuberance of lamellar base material is compared with relevant protruding ditch the lowest point
The projection of the protruding ditch of below part (6) plays face (8), and the top position that (7) are in the tower axle forms.
In the case, adjacent protruding ditch reaches the mutual spacing of crawling of chase each other, is preferably the half pitch that misplaces respectively.
The following describes effect of the present invention, filler of the present invention is to become skewed folding line by the axis that has with respect to tower, and its surface forms along the concavo-convex ditch of the one-tenth of horizontal expansion on the surface with respect to the lamellar base material with angle of inclination of the axis of tower, and make this ditch shape that becomes to crawl, constitute filler owing to make folding line become to stack mutually by the lamellar base material that multilayer is so constituted with reporting to the leadship after accomplishing a task shape, can realize the gas-liquid expansion, simultaneously, because because of the Liquid Flow destruction in boundary layer that become turbulence, thereby just can improve gas liquid contacting efficiency, and, again because the concavo-convex position of the ditch portion of chase that forms on lamellar substrate surface and protruding ditch becomes certain installation relation with the above-below direction of tower axle, thereby prevented that unwanted liquid is detained, liquid can flow glossily, thus, has further improved the effect of gas-liquid contact.
The present invention is described with reference to the accompanying drawings.Fig. 1 has represented along the filling of tower axle the oblique view of the state behind the filler of the present invention.Wherein, (1) is the tower axle, and (2) are rugose lamellar base materials, and (3) are the protruding ditches that forms on lamellar substrate surface, (4) expression chase.In addition, Fig. 2 is the oblique view of a lamellar base material.Protruding ditch (3) and chase (4) are disposed along the vertical direction interlacedly.Protruding ditch part is playing part (5) and be formed with into shape the lowest point, mountain valley (6) above the tower axle towards being formed with into shape gallery, mountain above the tower axle.In Fig. 2, the summit that part is played in the protruding ditch of (5) expression gallery, the protruding ditch of (6) expression the lowest point.In addition, (7) are to be positioned at the basal surface that the chase of top position, summit is sent out by the protruding ditch gallery portion of rising.(8) expression is positioned at the raised face (RF) of the protruding ditch of the beneath location of protruding cheuch.
At first, the effect of the ditch that becomes snakelike shape is explained, the flowing liquid upper surface (21) of running into the protruding ditch of lamellar base material promptly disperses expansion to the left and right downwards from tower axle top.The liquid of dispersion expansion flows down downwards from the lowest point (6) of protruding ditch.If the width that crawls of protruding ditch is little, and the degree of depth of ditch is big, the lateral magnification meeting of liquid further continues.The liquid that flows to the below is met the upper surface of the protruding ditch under it once more, similarly can be repeatedly to horizontal expansion with flow down downwards.
This occasion, if the width that crawls of protruding ditch is big, will hinder liquid to horizontal expansion, the lowest point because indiffusion can occur from certain falls so inappropriate situation downwards, therefore, in fact, the lowest point of protruding ditch and gallery rise the width that crawls of part be between adjacent bump distance 1/5 with in the interior scope better.
For make liquid on lamellar base material to horizontal expansion, when being placed on lamellar base material in the tower, making the mask of lamellar base material have with respect to the tower axle one to be subjected to liquid angle (α) is necessary (with reference to Fig. 2).If there is not this angle.That is, if the face of lamellar base material almost becomes plumbness, liquid will vertically fall, and just can not realize lateral magnification.In fact, be preferably between 90 degree-120 degree by liquid angle (α).
In the present invention, be subjected to the liquid angle in order to form this, and lamellar substrate surface is processed into the concavo-convex ditch of undaform, so that liquid is to horizontal expansion.It is passable that the waveform of ditch is made flexure plane, becomes good around curved surface.In addition, the concavo-convex cross sectional shape of ditch can be circle, ellipse, triangle, quadrangle, trapezoidal and other polygonal.
If ditch constitutes in such a manner, even the degree of depth of ditch is darker, liquid is flowed downwards from the lowest point, in addition, because the degree of depth of ditch is darker, just can realize increasing the surface area of filler, will can finish liquid lateral magnification that existing filler can not finish the while, prevent bias current and increase contact area.In addition, owing to make the ditch of the wave mode shape that becomes to crawl, liquid flow has just become turbulent flow, thereby can improve the contact effect of gas-liquid.In addition, to exemplify out a kind of more efficiently method below.This method is to make adjacent protruding ditch reach the mutual spacing of crawling of chase stagger (with reference to figure 3) each other.If by this way, the liquid bump that flows down from the lowest point of protruding ditch bumps against the bump of the protruding ditch that is positioned at its underpart and disperses expansion to the left and right, further flows down, and can collide the bump of protruding ditch repeatedly successively with that and disperses expansion.
The thing relevant with gas is described below.When gas rises below the tower, gas is disperseed to the left and right by bump towards the protruding ditch of tower axle below.This turbulent flow thus, just can make gas become turbulent shape to flow, owing to just can make gas-liquid contact effect increase.With similarly aforementioned, identical under the occasion that the shape spacing of crawling of ditch portion staggers with the situation of liquid, can realize good dispersion, diffusion and gas-liquid contact effect really.
Can make the shape of bump become standing shape, also can be circular-arc.
According to ditch portion being become crawl shape, just can realize the certain good diffusion of gas-liquid, simultaneously,, just can finish the destruction of liquid-gas boundary layer because of producing turbulent flow.
More than be that effect to snakelike ditch portion is described.The following describes the effect that prevents fluid retention.
For this filler, its performance is how much deciding by the contact of gas-liquid in unit volume.For realizing very good performance, be necessary to provide with the more gas-liquid contact area of per unit volume.If use the exchange column operation of the many fillers of gas-liquid contact area, the stuffing operation occasion few with using the gas-liquid contact area compared, and can make more liquid remain on filling surface, can have more liquid to fall again.The liquid that keeps on the filling surface when operation stops that the most important thing is in service at tower all falls downwards.This is because the stagnant liquid that operation remains in when stopping on the filler is known from experience a major reason that becomes the good contacting efficiency of obstruction gas-liquid.Because gas-liquid contact area size is generally ratio with liquid holdup,,, usually, liquid holdup is increased if increased the gas-liquid contact area in order to improve gas liquid contacting efficiency.Thus, just can not seek to raise the efficiency veritably.
Emphasis of the present invention is the delay that prevents that liquid is unnecessary.
Filler of the present invention is because be the folding line that has formed to tilt with respect to tower axis on lamellar base material, so its surface has two.One of them is the face towards the tower axis top, and another is the face towards the tower axis below.These two surfaces are relatively considered with the expansion of liquid and are detained relevant problem, and are special on the surface above the tower axis, can show various about matters significantly.Therefore, below the content put down in writing, be that the surface towards the tower axis top of lamellar base material is explained as object.
Shape to the ditch of lamellar base material describes, as filler of the present invention, usually, because lamellar base material processing is rolled into the embossment shape and forms ditch, the protruding ditch upper side (21) that is subjected to the liquid angle of forming with respect to the datum level of lamellar base material, have the above opening angle (β) (with reference to Fig. 2) of 90 degree.Here, if not crooked and be used in the tower being formed with into the lamellar base material of the ditch that is subjected to the liquid angle more than 90 ° with vertical configuration, the liquid bump that then flows down bump against protruding ditch above, and the expansion back falls from the lowest point to the left and right.Therefore, under situation like this, even the liquid angle that is subjected to of ditch is 90 degree, in addition, even the degree of depth of ditch is darker, because of the ditch shape that becomes to crawl, liquid still can flow downwards from the lowest point of protruding ditch.
But,, can occur and the mobile different phenomenon of aforesaid liquid and the phenomenon of generation liquid holdup for filler of the present invention because the lamellar wave mode that is processed into respect to the inclination of tower axle.At thin plate plate face this phenomenon is described towards tower axle top, for example, even the opening angle (β) with respect to the datum level of lamellar base material is designed to 90 degree, because the relative tower axle of lamellar base material becomes skewed, when being arranged on this filler in the tower, the liquid angle that is subjected on this part has just become the following angle of 90 degree.If the datum level gradient of lamellar base material is big more, this part be subjected to liquid angle (α) more little, under the less occasion of the trench depth width that crawls dark and/or ditch, liquid will remain in the chase., be under the upright occasion at lamellar base material unit inclination angle, the liquid that flows down glossily is the inappropriate like this phenomenon of its constricted flow to occur because of the gradient of lamellar base material for this reason.
In the present invention, adopted following structure for solving above-mentioned inappropriate situation.Promptly, the feature of filler of the present invention is under the state that it is arranged in the tower, the bottom surface (7) of the upper section chase at the top of the protuberance of the protruding ditch of lamellar base material (5) should form in this wise, make its raised face (RF) (8) that is higher than the protruding ditch of below part of relevant protruding ditch the lowest point (6), and be positioned at the top of tower axle.Promptly, as shown in Figure 3, bigger in gradient with respect to the tower axis (1) of lamellar datum level, in addition under the darker occasion of trench depth, protruding ditch raised face (RF) (8) compared with the below part of the lowest point (6) of relevant protruding ditch will appear in the bottom surface (7) of the upper section chase at the bump top (5) of the protruding ditch of lamellar base material, is positioned at the occasion of tower axle lower position.Also have Fig. 3 center line 20 expression horizontal lines.Having under the occasion of this relation, is liquid can take place be trapped in inappropriate like this situation in the chase.Based on this, in the present invention, the position relation of above-mentioned ditch is made qualification.
By so limiting the position relation of ditch, even the datum level of lamellar base material is with respect to also having under the big occasion of the gradient change of tower axle, even the degree of depth of lamellar substrate surface ditch becomes under the big situation liquid is flowed down glossily, be subjected to the liquid angle by adjustment, keep the liquid of necessary amount to become possibility when making the gas-liquid contact.
As mentioned above, the present invention reduced since make ditch become to crawl shape and because of the datum level of lamellar base material with respect to the delay of liquid in ditch that the inclination of tower axle produces, therefore can improve gas liquid contacting efficiency greatly.
Below, other various states of the present invention are described.
Fig. 4 is the oblique view of the another kind of lamellar base material of the present invention.Represented the state that the spacing between adjacent protruding ditch staggers mutually.In this figure, though being the half pitch shape, the spacing of crawling between protruding ditch staggers, the half pitch that staggers not is to be necessary condition of the present invention.In addition, as shown in Figure 5, can bore the hole (9) of size arbitrarily in any position of lamellar base material.
Also have,, be provided with between the lamellar base material of folding line, the lamellar base material that can one or more no folding line of clamping or the woven wire of netted thin plate or stretching, extension or by these materials that is combined into (10) by shown in Figure 6.
Also have, also can be by making the overlapping lamellar base material that forms the band folding line of the lamellar base material of polylith.
In addition, can form ditch concavo-convex of lamellar base material by the other lamellar base material of liner on a lamellar base material.
Further, filler of the present invention, the available metal manufacturing, also available plastics or glass or pottery are made.
As above said, filler of the present invention, when the state that filler is arranged in the tower, though the chase bottom surface (7) of the upper section at the top (5) that the protruding ditch of lamellar base material rises, should be positioned at tower axle top compared with the raised face (RF) (8) of the protruding ditch of below part of the lowest point (6) of relevant protruding ditch and be necessary condition, but, know that fully this relation on the thin sheet surface of the direction above the tower axle is set up for those skilled in the art.
