Definitions

  • the invention relates to a heat transfer plate configured to be arranged in a plate-and-shell heat exchanger. It also relates to a stack of such heat transfer plates and to a plate-and-shell heat exchanger.
  • Plate heat exchangers are used throughout industry as equipment for heating, cooling, heat recovery, condensation and evaporation. Heat exchangers may be of different types and designs, depending on e.g. the type of medium to be heated or cooled and on which application system the plate heat exchanger is part of.
  • plate heat exchanger is the so-called plate-and-shell type of heat exchanger, often referred to as a "plate-and-shell heat exchanger” or as a “circular plate heat exchanger”. This type is well suited for uses that involve high pressures and high temperatures.
  • the plate-and-shell heat exchanger comprises a stack of corrugated, circular or elliptical heat transfer plates that are made of metal and arranged in a vessel.
  • the heat transfer surface of the plate-and-shell heat exchanger is formed by the heat transfer plates, which are welded adjacent each other such that typically two channels are formed between the heat transfer plates.
  • the two channels are accomplished by alternatively welding the heat transfer plates at an outer circumference of the plates and at portholes of the plates, thereby creating alternate fluid channels. Fluid of one of the channels is then led through the stack of heat transfer plates via the portholes in the heat transfer plates, while fluid of the other channel is led through the stack of heat transfer plates via an outer circumference of the plates.
  • the flow of the fluids may be a counter-current, a co-current or a cross flow type.
  • the arrangement of the heat transfer plates renders the plate-and-shell heat exchanger resistant to thermal expansion, which makes it ideal for use at high-pressure and high-temperature conditions.
  • the design of the heat transfer plate must be taken carefully into consideration, even if the principal design of a plate-and-shell heat exchanger per se provides for high-pressure resistance (stress-resistance).
  • the design of the heat transfer plate is also important for how efficiently the plate transfers heat. However, if heat transfer is improved pressure-resistance is generally reduced, and vice versa.
  • the heat transfer plate is configured to be arranged in a plate-and-shell heat exchanger.
  • the heat transfer plate comprises an inlet port and an outlet port arranged at a distance from the inlet port.
  • the inlet port has a first inlet section that faces the outlet port and comprises a first fluid blocker, for distribution of at least a part of a flow of fluid over a second inlet section of the inlet port.
  • the outlet port has a first outlet section that faces the inlet port and comprises a second fluid blocker, for distribution of at least a part of a flow of fluid over a second outlet section of the outlet port.
  • the heat transfer plate comprises corrugations arranged intermediate the inlet port and the outlet port.
  • That the heat transfer plate comprises corrugations means that the heat transfer plate is corrugated, or that it has a corrugated profile.
  • the section of the inlet port that faces the outlet port represents a part of the inlet port that is closest to the outlet port, while the section of the outlet port that faces the inlet port represents a part of the outlet port that is closest to the inlet port.
  • the facing sections comprise a respective fluid blocker, no or a relatively small amount of fluid may flow from the part of the inlet port that is closest to the outlet port. In a corresponding manner, no or a relatively small amount of fluid may flow over a part of the outlet port that is closest to the inlet port.
  • the corrugations may comprise elongated ridges and grooves that are parallel to a first axis that is inclined by an angle of 15-75° in relation to a second axis that extends through a centre of the inlet port and through a centre of the outlet port.
  • Such an arrangement of the corrugations provides an efficient transfer of heat through the heat transfer plate.
  • all ridges and grooves of the corrugations may be parallel to the first axis.
  • the corrugations may surround the inlet port and the outlet port.
  • a first abutment section may be arranged around a periphery of a first side of the heat transfer plate.
  • a second abutment section may be arranged around the inlet port and a third abutment section may be arranged around the outlet port, at a second side of the heat transfer plate that is opposite the first side.
  • the first abutment section is then configured to be joined with a corresponding abutment section of a first, similar heat transfer plate that is arranged at the first side.
  • the second and third abutment sections are configured to be joined with corresponding abutment sections of a second, similar heat transfer plate at the second side.
  • the heat transfer plate may be configured to be joined with the first, similar heat transfer plate and the second, similar heat transfer plate by welding.
  • the first and the second fluid blockers may be arranged on the first side of the heat transfer plate.
  • the heat transfer plate, the inlet port and the outlet port may have circular shapes, and the fluid blockers may have the shape of circular arcs.
  • At least one of the fluid blockers may comprise openings such that an amount of fluid may flow past the fluid blocker.
  • the fluid blockers may be pressed into the heat transfer plate, such they form a respective fluid-blocking ridge.
  • the inlet port may be positioned at least 4 cm from a peripheral edge of the heat transfer plate.
  • the heat transfer plate may be configured to distribute the flow of fluid at a pressure of at least 80 bars.
  • a stack of heat transfer plates which comprises a number of heat transfer plates that include any of the above-described features.
  • a plate-and-shell heat exchanger which comprises a number of heat transfer plates that include any of the above-described features.

  • the inlet port 11 and the outlet port 12 for the first flow of fluid F1 are arranged at the first end plate 3, relatively close to an outer edge of the first end plate 3 and at opposite sides of a centre of the first end plate 3.
  • the inlet port 13 and outlet port 14 for the second flow of fluid F2 are arranged on the shell 5, at opposite sides of the shell 5.
  • the end plates 3 and 4 are rigidly joined to the shell 5, such that the end plates 3, 4 and the shell 5 have a cylindrical shape that allows a high pressure within an enclosure formed by the joined end plates 3, 4 and shell 5.
  • the end plates 3, 4 may be welded to the shell 5 or fixed to the shell 5 by means of bolts (not shown).
  • Two supports 17, 18 are attached to the end plates 3, 4 for allowing the plate-and-shell heat exchanger 1 to be placed on a foundation.
  • FIG. 2 a cross-section of the plate-and-shell heat exchanger 1 is illustrated.
  • the first flow of fluid F1 and the second flow of fluid F2 is led through a stack 10 of heat transfer plates that is arranged within the enclosure formed by the end plates 3, 4 and the shell 5.
  • the stack 10 of heat transfer plates typically includes 10-300 or even a greater number of heat transfer plates.
  • the first flow of fluid F1 and the second flow of fluid F2 are conveyed via two channels that are accomplished by alternatively welding the heat transfer plates in the stack 10 at an outer circumference of the plates and at inlet and outlet ports of the plates, thereby creating alternate fluid channels.
  • the first flow of fluid F1 is then led through the stack 10 of heat transfer plates via the ports in the heat transfer plates while the second flow of fluid F2 is led through the stack 10 of heat transfer plates via an outer circumference of the plates.
  • the heat transfer plates of the stack 10 are typically similar or even identical and are joined to each other by welding, even if other methods of joining may be used, such as brazing.
  • an inlet channel 111 for the flow of the first fluid F1 is formed through a first set of ports (inlet ports) in the heat transfer plates.
  • An outlet channel 121 for the flow of the first fluid F1 is formed through a second set of ports (outlet ports) in the heat transfer plates.
  • the inlet channel 111 and the outlet channel 121 extend along a respective axis A7, A8 that are parallel to a main axis A6.
  • the flow of the first flow of fluid F1 passes into the inlet channel 111 and further in between heat transfer plates that are welded to each other at an outer circumference, such as between heat transfer plate 2 and an adjacent, similar heat transfer plate 101.
  • the first flow of fluid F1 may be seen as divided into different fluid flow parts that pass between every second heat transfer plate in the stack 10, such as fluid flow part F11 that passes between plate 2 and plate 101.
  • fluid flow part F11 that passes between plate 2 and plate 101.
  • the flow of the second flow of fluid F2 reaches the stack 10 of heat transfer plates via the inlet 13 and passes further in between heat transfer plates that are welded to each other at ports (inlet and outlet ports) of the plates.
  • the second flow of fluid F2 passes between heat transfer plate 2 and an adjacent, similar heat transfer plate 102. A heat exchange between the first flow of fluid F1 and the second flow of fluid F2 may then take place.
  • the second flow of fluid F2 may also be seen as divided into different fluid flow parts that pass between every second heat transfer plate, such as fluid flow part F21 that passes between plate 2 and 102. When these fluid flow parts exit the heat transfer plates they "aggregate” into the second flow of fluid F2 and exit via the outlet port 14.
  • the heat transfer plate 101 may be seen as a first adjacent heat transfer plate 101 that is arranged at a first side 21 of the heat transfer plate 2, while the heat transfer plate 102 may be seen as a second adjacent heat transfer plate 102 that is arranged at a second side 22 of the heat transfer plate 2.

  • a so-called compensation plate stack 19 may be positioned between the first end plate 3 and the stack 10 of heat transfer plates.
  • the compensation plate stack 19 allows the heat transfer plates in the stack 10 to expand or shrink due to temperature changes, without imposing thermal fatigue to joints between the stack 10 of heat transfer plates and the end plates 3, 4.
  • the exemplified heat transfer plate 2 in the stack 10 of heat transfer plates is illustrated as seen from its first side 21. Most or even all of the heat transfer plates in the stack 10 may be identical with the heat transfer plate 2, including the first 21 and the second 22 adjacent heat transfer plates.
  • the heat transfer plate 2 has an inlet port 7 and an outlet port 8 that is arranged at a distance from the inlet port 7.
  • the inlet port 7 forms in combination with inlet ports of similar heat transfer plates the inlet channel 111 discussed above, while the outlet port 8 forms the outlet channel 121 together with outlet ports of similar heat transfer plates.
  • the inlet port 7 has a first inlet section 71 that faces, i.e. is closest to or is directed towards, the outlet port 8.
  • the first inlet section 71 comprises a first fluid blocker 74 that distributes at least a part F11 of the first flow of fluid F1 over a second inlet section 72 of the inlet port 7.

In this embodiment where the is only one inlet port and one outlet port, the flow over the second inlet section 72 has the same rate as the flow over the second outlet section 82.
