  • the invention relates to a device for the separation of gaseous or vaporous substances, especially isotopes, with different molecular weights and/or different gas kinetic cross sections. It consists of nozzles equipped with deflection walls to which the substances to be separated are fed by feed lines, if required in a mixture with light additional gases. in the following the mixture of the substances to be separated .and the light additional gas will be named feed gas.
  • Skimmer channels are assigned to the nozzles and equipped with skimmer diaphragms, which channels duct the different substances, separated into a heavy and a light fraction, into a discharge line for the heavy fraction and a line for the light fraction, respectively, adjacent feed and discharge lines having one partition wall in common.
  • A-device of this kind is known (German Patent No. 1 I98 328).
  • the gas mixture fed to the nozzle is separated into a heavy and a light fraction'with an enrichment of the heavy components occurring near the deflection wall.
  • the skimmer diaphragm separates the heavy fraction from the light one and feeds both to separate lines and chambers, respectively.
  • the purpose of the invention is to create a device for the separation of gaseous or vaporous substances, especially isotopes, which permits the application of relatively high gas pressures and in which, under the aspect of capital costs as well as operating costs, economic considerations are brought to bear to an increased extent.
  • fabrication and design methods will be shown which allow the simple fabrication and assembly of the individual components and the erection of individual separation stages or even a whole cascade in a minimum of space.
  • the solution of the problem according to the invention is to arrange the separation units consisting of nozzle, deflection wall, and skimmer channels always on the surface lines of a tube (separation element tube) which is subdivided by one or more partition walls into feed lines for the feed gas and discharge lines for the heavy fraction, and to provide for penetrations in the tube wall which connect the feed lines with the nozzles and the discharge lines for the heavy fraction with the skimmer channels of the heavy fraction.
  • the separation units and the feed and discharge lines are best routed parallel to the longitudinal axis of the tube.
  • the nozzles and the skimmer channels for the heavy fraction are separated from the skimmer channels for the light fraction by means of gas ducting devices attached to the outside of the tube wall, which devices are designed with curved nozzle walls (nozzle lips) and skimmer diaphragm, respectively, on their ends facing the deflection wall.

  • the sector chambers 13 and 15 act as feed lines for the feed gas, chambers 12 and 14 and the-additional channel 114 as discharge lines for the heavy fraction.
  • the feed gas is radially discharged to the outside from the sector chambers 13 and 1s (feed lines) through the penetrations 17 and is fed to the nozzle 19 by gas ducting devices 18.
  • the gas ductingdevices route the heavy fraction from the skimmer channel 111 through the penetrations 112 back into the sector chambers 12 and 14 (discharge lines).
  • the light fraction flows radially to the outside between the gas ducting devices 18 and 110 and is accommodated by a gas tight housing which will be explained in greater detail below.
  • the deflection walls are formed by grooves 118 made along-surface lines of the separation element tube 10.
  • Chambers 12, 14, and the central additional channel 1 14 are unilaterally'closed on one front side, chambers 14 so as to be distributed over the entire length of the channel, a decrease of static pressure resulting from the change in the gas velocity will be superimposed to the pressure loss due to friction. The undesirable pressure differences can be greatly diminished if the gas is withdrawn from this flow channel at both ends.
  • channel 114 is connected with the chambers 12 and 14 in the area ofits closed end via the penetrations 115 so' that the heavy fraction is withdrawn from chambers 12 and 14 through the chamber openings 116 and 1 17 in the front side as well as through the penetrations 115 at the other tube end via channel 114.

  • the massive profile strip 51 is combined with a fitting piece 52 includingthe deflection wall and having penetrations for the feed gas and the heavy fraction.
  • This design makes it 7 possible, as in the exampleshown in FIG. 3, to prefabricate the components 51 and 52, as a stable unit.
  • the tube 53 is provided with seams in whichthe profile strip and the fitting piece, respectively, are glued or soldered with the corresponding lug-shaped extensions 54 and 55.

  • the fitting piece 52' is aligned relative to the profile strip 51 in a similar way as in the example shown in FIG.
  • the alignment surfaces are in the area of the gas ducts.
  • This can be achieved by providing the profile strip or the tube and the fitting piece, respectively, with fins on the feed side as well as the discharge side for the heavy fraction, the fins being arranged like gear racks supported on corresponding contact surfaces of the opposite fitting piece with their free front faces, the contact surfaces being made to such tolerances that the nozzle lip and the skimmer assume a defined position relative to the deflection wall after assembly of the two components (profile strip and tube and fitting piece, respectively).

  • the upper part 61 may be a special profile strip which is put on the bottom part 66, which is either a profile strip or, respec tively, attached ,to the'separation element tube, or else the upper part 61 with its alignment section is part of the tube; wall of the separation element proper, while the bottom half 66 is a component of the chamber separation wall and the spider of the separation wall, respectively.
  • a special advantage of the latter integrating measure is the fact that no gas tight connections are required within the entire separation element unit and assembly is possible by merely pushing one part into' other. A particularly positive and frictional connection of these two parts is enabled by simply shrinking the tube wall on the spider of the separation wall.
  • the gas tight connection of the profile strip'61 with part 66 is made by soldering or gluing in this case, and the connection is secured by bent clampsor clampingstrips 611 before or after the connection is made.
  • Each separation stage and the separation cascade built up of such stages should have the smallest possible material content because the time required to attain product concentration in a cascade is directly proportional to the time of sojourn of the material in the individual stages and thus to the material content. For this reason, the plant volume should be as small as possible and the gas velocities attained in it should be as high as possible.
  • Rational design and economic operation of a plant must be safeguarded by a cost saving concept of the components and by a minimum requirement of floor space while leaving the possibility to repair cases of maloperation as speedily as possible.
  • the arrangement of the separation units on the surface line of separation element tubes is a particularly simple way of fulfilling the requirements of a specially compact and thus technically and economically advantageous design of the vseparation stages.
  • a multitude of separation element tubes 71 are arranged in parallel and are contained in a common container 72 accomodating the light fraction which is discharged from the separation element tubes.
  • the container72 has two opposite wall elements'725 and 726 which are penetrated by ends of the separation element tubes, the tube sector chambers 73 for the gas fed in being closed unilaterally on side of wall element 726 and the tube sector chambers 74 for removal of the heavy fraction being closed on side of wall element 725.
  • These wall components 725 and 726 are followed by one collection chamber each 76 and 78 having a tube connection 741 and 79, respectively, for feeding in the feed gas and removing the heavy fraction, respectively.
  • the container 72 holding the light fraction is connected with the suction pipe 71 l of a compressor system'with intermediate and final cooling (compressor with cooling devices 712, drive 713) by means of suction line 710 penetrating centrally through the collection chamber 76.
  • the compressed and re-cooled gas flows back into a collection chamber 77 concentrically envelopping the suction line 710.
  • This collection chamber 77 is equipped with a lateral discharge pipe 715 and has a common partition wall 75 with the collection chamber 76.
  • connection 715 is connected with connection 741, connection 716 with connection 79.
  • the marking gas flows from the compressor through the collection chamber 77 of the distributor section 780, through connections 715 and 741 into the collection chamber 76 and from there into the individual sector chambers 73 of the separation element tubes 71.
  • the light fraction is captured in the container 72 between wall sections 725 and 726 and the separation element tubes 71 and fed back to the compressor via the central line 710.
  • the heavy fraction reaches the upper collection chamber 78 and flows back to the container 72 via connections 79 and 716.
  • the tube 716 taking the heavy fraction back to the container is carried down to the vicinity of the lower wall section 725.
  • Its orifice 717 is nozzle shaped and penetrated into the suction pipe 718 for the light fraction.
  • the suction opening of the pipe 718 acts as a diffuser andthus forms a jet pump together with the orifice 717 of the tube 716.
  • the static pressure in the gas ducts of the heavy fractions can be increased to about 1.5 times the pressure in the gas ducts of the lighter fraction without resulting in noticeable reduc tion in separative work. At the same time, this increases the strength of the isotopic stream getting into the light fraction, as a clear function of the acting back pressure.
  • This characteristic of the separation nozzles can be utilized advantageously for fine regulation of the value of stream separation between light and heavy fraction of the mixture of isotopes (cut), which governs the optimum operation of a separation-cascade (cf., e.g.-) Atom oceantechnik 13, 359 1968)).
  • the cross section of nozzle 717 has been made variable so that the optimum operating conditions for the separation stages according to the invention can be established practically free of loss.
  • a regulating needle 719 shaped with respect to favorable flow characteristics is installed in the area of the orifice and can be moved in the direction of the axis of the nozzle; it can be shifted axially by means of a rod 720, penetrating to the outside through a gas tight seal 721..
  • the compact structure provides further special advantages for instal lation and assembly, checking and maintenance of separation stages. Especially a vertical arrangement of the separation stages results in very simple assembly and a particularly small space requirement. Since operational disturbances, especially when their causes are not'known exactly, are removed most rapidly and safely by replacing complete functional groups, the arrangement according to the invention of the single stage and of its line connections has been selected so that after four process lines have been disconnected, either the whole single stage can be replaced. as a complete unit by an operational replacement unit or,
  • connection of several separation stages in a separation cascade must be carriedoutin a well-known way so that the gas streams mixing at the connection points have the same isotopic compositions.
  • Such cascade is brieflyexplained on the basis of the example shown in FIG. 8 for stages with an isotopic stream separation ratio of l 1.
  • the figure shows separation stages 81 85 in a view looking in the directionof the axes of the separation element tubes towards the inlet lines 86 (corresponding to tube connection 716 in FIG. 7)and the discharge lines 87 of the heavy fraction (corresponding to tube 79 of FIG. 7).
  • Stage 83 e.g., is fed the initial mixture by the line connection 88 visible between'the stages (corresponding to connection 74l of FIG. 7) from the compressor of stage 82.
  • the light fraction produced in stage 83 is sucked in by the compressor of stage 83 after having been mixed with the heavy fraction coming from stage 85 via line 86, 87 and is taken to the next stage, 84, through line 89 (corresponding to cennection 715 in FIG. 7).
  • stage 83 flows through line 87 (corresponding to connection 79 in FIG. 7) to stage 81 where it is mixed with the light fraction of that stage, sucked in by the compressor of that stage and fed to stage 82 through connection 810.
