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.
  • a first abutment section is arranged around a periphery of a first side of the heat transfer plate.
  • a second abutment section is arranged around the inlet port and a third abutment section is 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 configured to be joined by welding 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 by welding with corresponding abutment sections of a second, similar heat transfer plate at the second side
  • the heat transfer plate comprises corrugations arranged intermediate the inlet port and the outlet port.
  • the heat transfer plate is configured to distribute the flow of fluid at a pressure of at least 80 bars
  • 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.
  • 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.
