Description
Technical field
The present invention relates to filler field, is specifically a kind of dumped packing.
Background technology
Filler is the core internals of packed tower, it contacts progress mass transfer for vapor-liquid two phases and heat exchange provides surface, with filling out
Other internals in material tower have together decided on the performance of packed tower.Filler can be generally divided into dumped packing and structured packing two is big
Class, dumped packing refer to filler of the installation based on huddling, and existing dumped packing can be divided mainly into annular, saddle type in shape
With ring saddle type, shape, the specification of dumped packing determine its pressure drop, flux, mass-transfer efficiency, intensity and mechanical property etc..Pall ring
Filler, is the height perforate ring packing equal with diameter, and rectangular opening window is provided with its side, and each hole window is equipped with curved to ring heart
Bent ligule, this filler have the following disadvantages：（1）Intensity is low, poor mechanical property；（2）The filler contact mutual in accumulation
Predominantly line contacts, and voidage is small and discontinuous, causes that pressure drop is big, gas is by the way that the resistance of packing layer is big, film forming is poor, mass transfer
Efficiency is low.Saddle packing is similar to horse-saddle, the predominantly fluid passage of arc in this packing layer, the voidage in packing layer
Continuous compared with ring packing, main arcuately passage flows gas upwards, therefore gas-liquid flows situation is preferable, but due to adjacent
Saddle packing be also easy to produce intussusception and overhead phenomenon, prevent a part of filler surface from being wet, that is, can't be effective
Mass transfer surfaces, therefore mass-transfer efficiency is relatively low.For improve dumped packing performance, generally take at present perforate on wall, internal structure,
The measures such as flat surface, design flange are avoided, but effect is still bad.In addition, existing dumped packing generally existing surface
The problem of utilization rate is low, causes its mass-transfer efficiency low.
The content of the invention
The purpose of the present invention is to solve above-mentioned the deficiencies in the prior art, there is provided a kind of dumped packing, solves existing dissipate
The shortcomings that filling material surface utilisation is low, mass-transfer efficiency is low, gas-liquid flows situation is poor, pressure drop is big, film forming is poor, and intensity
Height, mechanical property are good.
The technical problems to be solved by the invention are realized using following technical scheme：A kind of dumped packing, including fixation
The first Mobius Strip and the second Mobius Strip of connection；First Mobius Strip is thickeied by the first Moebius curved surface
Form, second Mobius Strip is thickeied by the second Moebius curved surface to be formed, the first Moebius curved surface and second
Moebius curved surface geometry mirror image each other, the Gaussian curvature at any point is zero on the first Moebius curved surface；First than crow
There is the first center circle of its width of decile on this curved surface, the second center circle for having its width of decile on the second Moebius curved surface,
The plane where plane and the second center circle where first center circle is orthogonal, the first center circle and the second center circle
With one heart；There is unique point A in first center circle, the first center circle is located at the first Moebius curved surface in the section at point A；
There is unique point B in second center circle, the second center circle is located at the second Moebius curved surface in the section at point B；Point A exists
In second center circle and point B is in the first center circle, and the distance of point A and point B is the first center diameter of a circle.
Technical scheme also has：The girth of first center circle is the nine of the first Moebius curved surface width
Times.Multiple is bigger, inlay card, foaming, specific surface area more easily occurs（Total surface area of the filler of unit space accumulation）Reduce,
Mass-transfer efficiency is caused to reduce.Multiple is smaller, and easier stagnant liquid, blocking, and voidage and flux reduction occur, pressure drop increase, leads
Mass-transfer efficiency is caused to reduce.
Relative to the prior art, dumped packing of the present invention has the beneficial effect that：（1）Utilize the unilateral surface of Mobius Strip
Characteristic, surface utilisation is high, and mass-transfer efficiency is high；（2）It is mainly curved channel in packing layer, therefore gas-liquid flows situation is good
And good film-forming property；（3）First Mobius Strip and the second Mobius Strip are connected according to certain morpheme, its structure is not likely to produce
Intussusception and overhead phenomenon, mass-transfer efficiency are high；（4）Filler predominantly point contact in accumulation, pressure drop is small, mass-transfer efficiency is high；（5）
First Mobius Strip and the second Mobius Strip junction form reinforcement structure, during manufacture without perforate on wall, internal structure,
Flange, intensity is high, mechanical property is good.

Embodiment
In order to clarify the technical characteristics of the invention, the specific embodiment of the invention is made below according to attached drawing further
Explanation.
The embodiment of the present invention one shown in Fig. 1 ~ Fig. 5, as shown in the figure, a kind of dumped packing, including be fixedly connected
One Mobius Strip 1 and the second Mobius Strip 2.
First Mobius Strip 1 is thickeied by the first Moebius curved surface 3 to be formed, and the second Mobius Strip 2 is not compared by second
This black curved surface 4, which thickeies, to be formed, and the first Moebius curved surface 3 and the second Moebius curved surface 4 geometry mirror image each other, first than crow
The Gaussian curvature at any point is zero on this curved surface 3.As it can be seen that edge on the first Moebius curved surface 3 and the second Moebius curved surface 4
The curve of width is straightway.
There is the first center circle 5 of its width of decile on first Moebius curved surface 3, the first center circle 5 is first not than crow
A plane circular curve on this curved surface 3；There is the second center circle 6 of its width of decile on second Moebius curved surface 4, in second
