Description
SPECIFICATION
Heat and mass transfer apparatus
The present invention relates to a heat and mass transfer apparatus.
The present invention provides a heat and mass transfer apparatus, comprising a housing in which are arranged tubes the inlet and outlet ends of which are assembled in headers, the top and bottom parts of the housing being provided with elongate, hollow, converging branches the bases of which adjoin the housing, wherein the tubes are assembled in a bank and their header is arranged in one of the branches.
The heat and mass transfer apparatus according to the invention can be used as a heat exchanger for heating liquid and gaseous media or as a cooler for such media. When equipped with palladium alloy tubes, the apparatus of the present invention provides a diffusion action and can be used for high purification of hydrogen and separation of the same from gaseous and liquid mixtures. When equipped with tubes made of a membrane catalyst or another catalyst, for example an alumina-base metal, the apparatus works as a catalyst chamber.
The constructional arrangement of the apparatus according to the invention eliminates stagnant zones and provides uniform distribution of the velocity of the flow of reagents throughout the cross-sectional area of the apparatus as well as uniform exposure of the external surfaces of the tubes to the substances taking part in the process of heat and mass transfer.
The branches can be horn-shaped to provide for unform distribution of the flow velocity, with conical headers contained in the branches.
The branches can also be cone-shaped, in
which case their manufacture is simplified, whereas provision is likewise made for uniform distribution of the flow velocity.
The apparatus can be additionally provided with at least one tube bank located in the same housing. The inlet and outlet ends of the tubes in this bank are also assembled in headers, the
headers being alternately installed in the top and bottom branches. This constructional arrangement
of the apparatus permits the maintenance of
uniform distribution of the flow velocities and
proper exposure of the tubes to the flow.
The apparatus housing and the tube banks can
be made in the shape of a right prism, the tube
banks being arranged with respect to each other
so that the outlet holes of the tubes are disposed
in opposite directions and staggered. This provides
a snug arrangement of the tubes in the apparatus,
which enlarges the active surface of the tubes per
unit volume of the housing, and consequently
increases the working capacity of the apparatus.
The apparatus housing and tube banks can be
in the shape of a cylinder to simplify manufacture.
In addition, the inlet and outlet ends of the
tubes in the bank can be fitted in a conically
shaped header. This permits uniform distribution
of the flow inside the tubes to be effected and assists elimination of stagnant zones.
The tubes of the bank can be coiled together in a helix, which eliminates tube vibration at high velocities of the flow toward the bank and enhances the operational dependability of the whole apparatus.
The same effect is achieved when each tube in the bank is shaped helically, with the bottom coil changing to a straight piece passing inside the helix toward the bank header, there being a ratio of 0.2 to 1.0 between the tube outside diameter and the lead of the helix, while the tubes are assembled in banks so that the convolution of each helix fits into the space between the convolutions of the adjacent helices. This provides for the external surfaces of the tubes inside the bank to be fully exposed to the flow.
The above-mentioned ratio of the tube outside diameter to the lead of the helix is chosen with respect to the following considerations. If the ratio exceeds 1.0, the helix convolution cannot enter the space between the convolutions of the adjacent helices. If the ratio is less than 0.2, the helix convolution fits too loosely between the convolutions of the adjacent helices, which results in undesirable vibration of the tubes during operation of the apparatus.
Alternatively, each tube in the bank can have the shape of a flat spiral and be positioned one on the other, the inlet and outlet ends of the tubes being secured in tubular headers positioned perpendicular to the plane of the spiral. This constructional arrangement enables the apparatus volume to be filled with tubes to a maximum, thereby increasing the working capacity of the apparatus and simplifying the header construction.
The tubes can have the shape of a double-start flat spiral, being positioned one on the other so that each succeeding spiral is in mirror symmetry with the adjacent one. This simplifies the bank assembly and enables the apparatus volume to be filled with tubes to a maximum.
The tubes can alternatively have the shape of an Archimedean spiral, which allows the number of soldered joints between the tubes and the headers to be reduced, thereby enhancing the operational dependability of the apparatus.
The tubes can be made of a material possessing catalytic properties, which enables the heat and mass transfer apparatus to be used for performing various catalytic processes. For example, when tubes having a surface catalyst layer of nickel or palladium are employed, the processes of hydrogenation of dehydrogenation can be performed in the apparatus, in which case cooling or heating of the apparatus can be effected by feeding a heat transfer medium inside the tubes.
The tubes can be made of a membrane catalyst selectively permeable to hydrogen, which adapts the apparatus for performing one or two catalytic processes, utilizing the heat liberated in one process for effecting an endothermic process. In such an apparatus decomposition of catalytic conversion of substances can also be effected for the purpose of obtaining highly clean hydrogen.
The tubes can be made of a palladium alloy permeable to hydrogen, which enables the heat and mass transfer apparatus to be used as a diffusion apparatus for producing highly clean hydrogen intended for enriching gaseous and liquid products, or for cleaning various substances of hydrogen.

The heat and mass transfer apparatus shown in the drawings comprises a housing 1 equipped with converging branches 2 of the larger ends of which have the shape of the centre part 3 of the housing 1, and further comprises banks 4 of tubes 5 the ends of which are assembled in a header 6.
The branches 2 can be horn-shaped as shown in
Figure 1 or cone-shaped as shown in Figure 2.
The tube banks 4 can be in the shape of a right prism, in which case the header 6 is cone-shaped and has a partition 7 and a tube sheet 8 into which the tubes 5 are fitted as shown in Figures 3 and 4.
In this case the housing 1 of the apparatus also has the shape of a right prism, the tube banks 4 are positioned in the housing 1 in the opposite directions, and the headers 6 are installed in the top and bottom branches 2 as shown in Figures 1 and 5.
If the tubes 5 are coiled together in a helix, the tube bank 4 has the shape of a cylinder and the ends of the tubes are secured in the header 6 (Figures 6 and 7).
When each tube 5 forms a helix 9 (Figure 9), the tube ends are secured in the tube sheet 8 of a conical header 10 having an inlet pipe 1 With this construction, the inlet ends 12 of the tubes 5 are united by the pipe 11, whereas the outlet ends 13 are united by the conical header 10. In this case the tube bank 4 has the shape of a cylinder (Figures 8, 9, 10 and 11).
The lead of the helix 9 is so dimensioned that the space 14 between the helix convolutions is equal to or greater than the diameter of the tubes 5 and the ratio of the tube outside diameter to the lead of the helix is 0.2 to 1.0, which provides for a snug arrangement of the tubes 5 in the bank 4 due to the fact that the convolutions 1 5 of the helices 9 fit into the spaces 14 between the convolutions of the adjacent helices (Figures 10 and 12).
If the tube banks 4 are in the shape of a cylinder, the housing 1 is also cylindrically shaped and the banks 4 are positioned in the housing 1 in opposite directions, for example in a hexagonal arrangement (Figures 1 and 13).
The tubes 5 can be formed into double-start flat spirals 16 (Figure 14) and assembled in banks 4 so that each succeeding spiral 1 7 is turned through 1 80O in mirror symmetry with the preceding one, the spirals being placed one on the other. In this case the inlet and outlet ends of the tubes 5 are fitted in headers 1 8 constructed in the form of tubes positioned perpendicular to the plane of the spiral (Figures 1 5 and 16).
The location of the inlet and outlet ends of the tubes 5 is determined by the number and position of the headers 1 8. Thus the headers can be positioned at an angle of 180 , 900 and 600 (Figures 18 and 20). Figures 17, 19 and 21 illustrate the construction of the tube banks and the assembly of the tubes 5 in the headers 18.
The tubes 5 can have the shape of a double
Archimedean spiral 1 9 which forms two spirals arranged one upon the other (Figures 22 and 23).
Two headers 1 8 suffice for assembling the tubes 5 in banks 4 (Figure 24).
The bank 4 of the tubes 5 coiled in flat
Archimedean spirals has the shape of a cylinder and is located in the housing 1 either singly (Figure 2) or in an assembly (Figure 13).
The tubes 5 of the banks 4 can be located both in the centre part 3 of the housing 1 and in the branches 2 (Figure 25) for the interior of the apparatus to be used to the full.
The heat and mass transfer apparatus of the present invention operates as follows.
Depending on the heat and mass transfer process to be performed in the apparatus, the tubes 5 are made of either a structural material for the apparatus to work as a heat exchanger, a catalyst or a membrane catalyst for the apparatus to work as a chamber for performing one or several catalytic processes, or else a palladium alloy permeable to hydrogen for the apparatus to work as a mass transfer diffusion cell to clean and separate hydrogen.
When the apparatus is used for heat exchange, a heat transfer medium is fed through the branches 2 into the housing 1. The substance to be heated is fed into the tubes 5 through the header of the tube banks 4. As the heat transfer medium passes down through the housing, it gives up heat through the walls of the tubes 5 to the substance being heated. The waste heat transfer medium is discharged from the apparatus through the bottom branch 2, whereas the heated substance is let out through the headers of the tube banks 4. It is also possible to feed the heat transfer medium into the tubes 5 and the substance into the housing of the apparatus.
If the tubes 5 are made of a catalyst or coated therewith, a reagent is fed into the housing 1 through one of the branches 2. As the flow reaches the surface of the tubes, the reagent undergoes conversion. The products of the reactions are discharged through the other branch 2. To heat or cool the apparatus, a heat transfer medium is pumped through the headers of the tube banks 4.
Tubes made of a membrane catalyst are used for the apparatus to work as a heat and mass transfer apparatus.
A substance which, for example, is to be dehydrogenized is fed into the housing 1 through the top branch 2.
Another substance which, for example, is to be hydrogenized, if fed through the headers of the tube banks 4.
During the dehydrogenation reaction hydrogen is evolved on the outside surface of the tubes of the membrane catalyst. This hydrogen diffuses into the tubes 5 and on the interior surface thereof undergoes a hydrogenation reaction with the substance contained in the tubes. The product of the dehydrogenation reaction is discharged through the bottom branch 2, whereas the product of hydration is discharged through the headers of the tube banks 4. It is also possible to arrange the process so that the substance to be dehydrogenized is fed into the tubes and the substance to be hydrogenized is fed into the housing.
For the apparatus to work as a mass transfer apparatus, for example for producing highly clean hydrogen, the tubes 5 are made of palladium alloy (80 percent of palladium, 20 percent silver). A mixture containing hydrogen (for example water gas) is fed into the housing 1 through the top branch 2 and the hydrogen passing through the walls of the tubes 5 is discharged through the headers of the tube banks 4. The mixture deplete of hydrogen is discharged through the bottom branch 2.
In the heat and mass transfer apparatus of the present invention the tubes 5 are shaped according to various embodiments. All of them ensure efficient exposure of the tube walls to the flow, improved heat rejection in exothermic reactions, and improved contact of reagents with the tube surfaces, whereby the yield of the desired products and the working capacity of the apparatus are substantially increased.
Due to the fact that the tubes 5 are assembled in banks 4, replacement thereof is case of malfunctioning is facilitated.
The use of the tubes 5 in the shape of flat and
Archimedean spirals makes in possible to use tubing as long as 4 meters and more, whereby the number of soldered joints is decreased, assembly technology simplified and operational dependability enhanced.
Furthermore, these embodiments provide a high ratio of the tube surface area to the volume of the apparatus, which produces a 1.5 to 2 times increase in the working capacity per unit volume of the apparatus.
