Definitions
- the invention relates to a tube bundle high pressure heat exchanger according to the preamble of claim 1.
- Tube bundle heat exchangers are well known.
- All these heat exchangers have in common that a working medium to be tempered is passed through a multiplicity of tubes which are combined to form a tube bundle and which are surrounded by a temperature-control medium. Due to the temperature exchange, the working medium flowing through the tubes can be brought to the desired temperature, ie heated or cooled.
- the field of application of such tube bundle heat exchangers is extremely diverse.
- a small field of application is the temperature control of working media in the field of polyurethane processing.
- the two components isocyanate and polyol can be heated to the required temperature, for example, 20 ° C.
- a heat exchanger in a conventional manner either in the return line to the material storage or arranged between the material storage and the high-pressure pump.
- the problem here is that so that the temperature control of the working media can not be performed immediately before the mixing head, since, for example, by the operation of the Pump generated heat is transferred to the working fluid, which is then heated in an undesirable manner supplied to the mixing head.
- Object of the present invention is to provide a
- An essential idea of the present invention is to introduce the tube ends of the individual tube of the tube bundle heat exchanger into precisely executed holes of end plates and to seal them with a seal opposite the tempering space in which the temperature control medium is located. If the two end plates are set against each other, then the pipes arranged therebetween are also fixed and can move, if at all, only in a minimal range in the axial direction. Due to the precise shape of the bore in combination with the seal and pressure requirements of 250 bar and above can be met. Overall, can be Avoid complex welding of the pipe ends with the end plate with this construction. The connection of the individual pipe interiors is made depending on the construction in one or both end plates. Depending on the embodiment of the tube bundle high-pressure heat exchanger, one or more flow spaces may be provided in a closure plate. The arrangement and design of the flow spaces depends on the intended guidance of the working medium as well as the tempering medium. Individual options will be discussed below.
- the flow spaces in the end plates can be produced by a multiplicity of blind bores, with the opening of the blind bore being sealed to the outside environment with grafts.
- the end plates are the most complex to be machined workpieces of the entire workpiece.
- a significant price reduction can also be achieved by a corresponding increase in the number of units.
- the determination of the end plates against each other can for example be done by being supported in the direction of each other by the housing.
- the housing which is preferably formed in a cylindrical shape, are supported on corresponding seats of the end plates.
- the two end plates can be braced for example by the use of tie rods, which in one embodiment radially outside the tube housing, distribute over the outer circumference of the housing and extend parallel to the axis of the tube housing.
- the housing is usually sealed at the transition to the end plates, so that no temperature control can escape from the tempering to the outside environment.
- FIG. 1 is a perspective view of an assembled tube bundle high pressure heat exchanger according to the invention
- FIG. 2 is a side view of the tube bundle high pressure heat exchanger of FIG. 1,
- Tube bundle high pressure heat exchanger according to section A-A of Fig. 4a,
- Tube bundle high pressure heat exchanger is only an alternative of the invention, but is not intended to be limiting since the invention also encompasses many other embodiments that are within the scope of those skilled in the art.
- Fig. 1 shows a tube bundle high pressure heat exchanger according to the invention in a perspective view, with only the two end plates 12 and 14, the interposed housing 16, which is designed in a cylindrical shape, and a plurality of tie rods 18 are shown.
- the cylindrical tube 16 designed as a housing sits on both sides on a corresponding cylindrical seat 42 of the end plates 12 and 14. In this way, the two end plates 12 and 14 are toward each other as well fixed in the radial direction. The two end plates 12 and 14 form together with the housing 16 in the interior of the tempering 15.
- a plurality of tie rods 18 are provided, which are aligned parallel to the axis of the housing 16 and the two end plates 12 and 14 with the interposition of the housing 16 clamp together.
- each tie rod extends at each end through a hole in the end plate 12 and 14.
- Fig. 1 only the threads 20 of the Glasstangenenden are shown on the right side in the picture. Nuts are screwed onto these threads when fully assembled.
- the present tube bundle high-pressure heat exchanger according to FIG. 1, with its end plates 12 and 14, the housing 16 and the tie rods 18, is a very compact form.
- each tube 17 is arranged, as can be seen in particular from Figures 3, 5 and 6.
- the respective pipe ends are accurately received in holes 36.
- seals 40 which seal the flow interior of each tube 17 relative to the temperature control 15.
- Each of the bores 36 has a stepped seat 38 designed as a stop, which prevents an axial displacement of the tube beyond a certain extent.
- the individual tubes 17 are respectively inserted into the respective holes 36 with a precise fit and sealed with the seals 40.
- the length of the tubes with respect to the seats 38 is chosen so that a very small clearance of, for example, 1 mm is possible.
- the seats 38 prevent the tubes from moving too much in the axial direction and, for example, escape from the bores, thereby disengaging the seals 40.
- a first flow space 32 which is also via the holes 36 in the connection plate 12 with a certain number of cooling tubes 17 in conjunction.
- These tubes are called tubes of the first kind below.
- a further, in the present case smaller flow space 31 is formed, which connects the lower three tubes 17 with each other.
- These tubes are called tubes of the second kind below. This flow space is accessible via a connection 29.
- the first larger flow space 32 is accessible via a port 27.
- the flow space 30 of the end plate 14 is not accessible from the outside.
- the flow path of the medium to be tempered by the tube bundle high pressure heat exchanger as follows.
- the working medium flows via the connection 29 into the flow space 31 and from there into the three lower cooling tubes 17 of the second type.
- the working medium flows in the direction of the end plate 14 and is thereby heated in the tempering space in which the tubes from the temperature control medium to be flowed around, influenced by temperature.
- the working medium flows into the flow space 30 and from there it distributes itself into the remaining tubes 17 of the first type, in which it in turn flows in the direction of the end plate 12. On its way through the pipes, it is again influenced by temperature in the temperature control room by the temperature control medium.
- the working medium flows into the common flow space 32 and from there it can be removed via the connection 27 serving as a drain.
- the temperature control can be passed through the temperature control 15 in various ways.
- two connections 24 and 25 are arranged in the end plate 14, which communicate with the temperature control chamber 15 via further bores 33 ', 33 "
- tempering medium in the region of the end plate 12 can be introduced into the temperature control chamber 15 via the tempering medium connections 24 and 25, guided through the tempering space 15 and removed from the tempering space 15 in the region of the end plate 14.
- two sealing plugs 28 'and 28 are arranged in the end plate 12, which close off holes provided in the end plate 12 and pass through them Connection 24 with a stopper too close, however, replace the plug 28 'by a connector.
- the temperature control medium are supplied, which is then discharged via the terminal 25 again. It is also possible - depending on the design of the flow spaces - in the end plates to initiate the working medium on one side of the tube bundle high-pressure heat exchanger and dissipate on the other side again. In this case, only one flow space must be provided on both sides, which connects all the tubes 17 fluidically with each other.
- the present embodiment enables a very simple and cost-effective production of a corresponding tube bundle high-pressure heat exchanger.
- the most complex are the respective end plates 12 and 14 in the manufacture. However, a price reduction can be achieved by producing a corresponding number of end plates.
- the remaining components such as the length of the housing 16, the length of the tubes 17 and the length of the tie rods can be selected accordingly, so that a heat exchanger longer or shorter design can be made. On the end plates 12 and 14, this has no effect.
