Definitions
- the invention relates to a heat exchanger with at least one Heat exchanger block and an insulation tank surrounding the heat exchanger, fastening means are provided to hang the heat exchanger block in to attach the insulation container and its use in one Cryogenic air separation plant.
- the feed air to be separated When air is decomposed at low temperatures, the feed air to be separated must be on the Process temperature are cooled. This is usually done through indirect Heat exchange of the feed air with that obtained in the air separation plant Product streams.
- the Main heat exchanger In systems in which large amounts of air are processed, the Main heat exchanger through several heat exchanger blocks connected in parallel realized. The individual heat exchanger blocks are usually as Plate heat exchanger trained.
- the main heat exchanger is thermally insulated by inserting the Heat exchanger in a thermally insulated insulation container, a so-called Cold box.
- a thermally insulated insulation container a so-called Cold box.
- Various methods are known for heat exchanger blocks in the insulation container.
- the heat exchanger blocks on stands or supports on the Place the floor or on the foundation of the insulation housing.
- the heat exchanger block is located on two opposite Side profiles attached, which then run across the isolation room Place the support on and hold the heat exchanger block. It is also possible to attach tie rods to laterally attached profiles, with the help of which Heat exchanger is suspended from the ceiling beams of the insulation room.
- WO 99/11990 describes the heat exchanger block on the warm one End, that is to say in the upper area, to be held with support brackets and at the cold end to be braced diagonally in the isolation room using rope-shaped elements.
- the object of the present invention is therefore to develop a heat exchanger which is fixed in the insulation tank so that the piping is as simple as possible and avoided or at least avoided the cable loops for the shrinkage compensation be kept small.
- the heat exchanger block is fastened in such a way that thermally induced Changes in the pipes connected to the heat exchanger block a change in position of the block can be compensated. For example, at Cool down the system's heat exchanger block with the shrinking piping moved.
- the heat exchanger block is preferably fastened in the insulation container in such a way that that its lower end can be moved in at least two spatial directions.
- the heat exchanger block is particularly preferably freely movable above its Focus hung.
- the heat exchanger block at the top end will be the warm one Feed air and the cold product gases are fed in at the lower end.
- Corresponding only experience those with the lower, cold end when starting off or changing loads noticeable changes in length of the pipes connected to the heat exchanger block, since the temperature changes at the warm end are only slight.
- the heat exchanger block can be suspended above its center of gravity its lower end can be deflected relatively easily. On the bottom end connected pipelines, the deflection of the Heat exchanger blocks cause only small forces. A Inadmissibly high stress on the pipes is avoided.
- the invention has proven particularly useful in a heat exchanger which comprises at least two, preferably at least four, heat exchanger blocks.
- the invention is particularly suitable for heat exchangers that have eight or ten Include heat exchanger blocks in two rows of four or five blocks.
- Complex piping is necessary to keep the feed air to be cooled and that in counterflow distribute the guided product flows to the individual heat exchanger blocks.
- the inventive attachment of the heat exchanger blocks simplifies the Piping, reduces the size of the insulation tank and thus leads to a clear one Cost cutting. This is especially true if the individual Heat exchanger blocks have feed and / or discharge lines that are in a common Lead manifold.
- Fastening means are preferably provided which have joints so that the heat exchanger block can be deflected around the hinge axes.
- a such gimbal suspension is relatively inexpensive feasible and has proven to be particularly cheap in practice.
- FIGS 1 and 2 show the upper end of a heat exchanger block 1, which in the Main heat exchanger of a cryogenic air separation plant is used.
- the entire main heat exchanger consists of several such parallel connected Heat exchanger blocks 1.
- the heat exchanger block 1 has a width of up to 240 cm.
- a collector distributor 2 On the Heat exchanger block 1 is a collector distributor 2, a so-called header, attached, from which one or more pipes, not shown, lead away.
- the steel plate 4 is suspended from a double T-beam 8, which is not in the Coldbox shown is attached and carries the heat exchanger block 1.
- the joint 7 allows movement in the plane of the steel plate 4 or around an axis 9 perpendicular to the steel plate 4.
- the heat exchanger block 1 is thus cardanic by two perpendicular to each other horizontal axes 6, 9 rotatably suspended.
- the arrangement of the two aluminum plates 3 and the steel plate 4 is chosen so that the suspension point 10 is perpendicular is located above the center of gravity of the heat exchanger block 1.
- the joint 7 is arranged so that the axis 9 to the project-specific Requirements, that is to say for a specific version of the heat exchanger occurring or calculable pipe tensions is adjusted.
- Pipelines for supply and discharge to each other in heat exchange bringing fluid flows attached At the lower end of the heat exchanger block 1 are one or more, not shown Pipelines for supply and discharge to each other in heat exchange bringing fluid flows attached. With load changes and with warm and Cold running of the system experiences these pipes due to thermal conditions Length changes of about 3 to 4 mm per meter of pipeline length. Through the suspension of the heat exchanger block 1 above his The center of gravity is already relatively low at its lower end attacking forces deflected. The deflection of the heat exchanger block 1 is the same thermally induced changes in pipe length, so that on cable loops for the shrinkage compensation in the pipelines can be dispensed with.
