Definitions

  • the invention is in the field of plate heat exchangers for drying a gaseous Medium, especially air.
  • Gaseous media such as air
  • the gaseous medium usually has certain Meet properties for the production process, for example, a predetermined Purity or have a minimum moisture content.
  • plate heat exchangers which are used to a gaseous medium, For example, compressed air to dry, so that the gaseous Medium only has a predetermined moisture content.
  • the gaseous medium is introduced into the plate heat exchanger through an input port fed. Subsequently, the thus fed moist incoming gas stream flows through a Gas-gas heat exchanger.
  • the gas-gas heat exchanger is in the plate heat exchanger in formed a portion of a stack of plates, which are used to form flow areas between the plates are interconnected.
  • the incoming moist gas flow away from the input port and a dried one Output gas stream, which are then fed back into the production process can, to an output terminal through separate flow areas in the plate stack.
  • the moist input gas stream and the dried starting gas stream flow in countercurrent, on the one hand to pre-cool the moist incoming gas stream.
  • the dried starting gas stream by heat transfer from the wet inlet gas stream heated to the previously dried starting gas stream.
  • the moist input gas stream passes from the gas-gas heat exchanger in this case Gas-refrigerant heat exchanger in the plate stack, which also has several flow areas between the plates of the stack.
  • the gas-refrigerant heat exchanger flow the precooled input gas stream and a countercurrent refrigerant, so that the moist incoming gas stream is cooled, resulting in the subsequent convection of the moisture particles the input gas stream leads, so that the input gas stream is dried.
  • the dried starting gas stream formed in this way flows through an overflow component from the outlet of the gas-refrigerant heat exchanger to the gas-gas heat exchanger, where it is reheated by absorbing heat from the incoming input gas stream.
  • the thus heated starting gas stream flows through the output port of the plate heat exchanger for further use.
  • the object of the invention is therefore to provide a plate heat exchanger for drying a gaseous Specify medium, which under operating conditions, a high pressurization allowed and holds this state, so that the safety standards are guaranteed.
  • the invention includes the idea of using a plate heat exchanger for drying a gaseous medium, in particular air, which in a stack of plates, a gas-gas heat exchanger and a gas-refrigerant heat exchanger, an overflow component in a flow connection between the outlet of the gas-refrigerant heat exchanger and the gas-gas heat exchanger by means of a stack of adjacent ones Form plates, which form to overflow areas between the adjacent Plates are interconnected, wherein between facing side surfaces of the adjacent Plate contact areas are formed, in which the facing side surfaces connected to each other.
  • a direct contact between the produced facing side surfaces of the adjacent plates of Matterströmbauteils wherein the contact may optionally be mediated by a suitable connecting means.
  • An expedient embodiment of the invention provides that the adjacent plates at the deflecting component are soldered together, whereby on the one hand a reliable solid connection the adjacent plates is guaranteed.
  • this way can Connecting the adjacent plates of Matterströmbauteils the same manufacturing technology used, as it is commonly used for connecting the plates of the stack in which the gas-gas heat exchanger and the gas-refrigerant heat exchanger are formed.
  • the contact areas in the Kochströmbauteil edge contact areas include, in which, optionally mediated by a connecting material, edge portions of the facing side surfaces of the Touch adjacent plates. In this way, a peripheral on the edge of Kochströmbauteils pressure-resistant connection between the adjacent plates of the stack in the Overflow component allows.
  • the contact areas in the overflow component comprise surface contact areas in which, optionally mediated by a connecting material in each case in a central region of adjacent plates of a plate plane projecting portions of the facing Touch side surfaces of adjacent plates.
  • the strength of the adjacent plates of Matterströmbauteils is at a favorable Embodiment of the invention improved by the fact that the adjacent plates of the Kochströmbauteils have an embossed surface structure at least in some areas. hereby In particular, the surface stability of the adjacent plates of the overflow component optimized.
  • a space-saving arrangement of Matterströmbauteils in the formation of the plate heat exchanger is achieved in a preferred embodiment of the invention in that the Kochströmbauteil arranged on an outer plate of the stack of plates surface resting is. In this way, as short as possible overflow connection between the Output promoted the gas-coolant heat exchanger and the gas-gas heat exchanger.
  • FIG. 1 shows a plate heat exchanger 1 for drying a gaseous medium, in particular Air, in longitudinal section.
  • the plate heat exchanger 1 comprises a stack 2 of a plurality of plates 3, which in the embodiment in the brazed plate heat exchanger are soldered together in the usual way, so that between the several plates 3 more Flow regions 4 are formed in a channel shape.
  • a gas-gas heat exchanger In an upper section 5 of the plate heat exchanger 1 is a gas-gas heat exchanger with the aid of the plurality of plates 3 and the flow areas 4 6 formed.
  • the gas-gas heat exchanger 6 flows a humid inlet gas stream 7, which is fed via an input terminal 8a, in the flow areas 4 down in countercurrent to an upwardly flowing output gas stream.
  • the moist input gas stream flows 7 between the plates 3 in a lower portion 10 of the plate heat exchanger 1, in which a gas-refrigerant heat exchanger 11 is formed.
  • a gas-refrigerant heat exchanger 11 is a coolant 12 via a coolant connection 13 between the plates. 3 fed so that the coolant 12 flows upwards between the plates 3, d. H. downhill flowing, moist incoming gas stream 7 against.
  • Via a coolant outlet 14 the coolant 12 leaves the plate heat exchanger 1 and is itself a cooling again fed.
  • the humid input gas flow 7 cooled below the predetermined dew point for each gaseous medium, so that Moisture components condense and in a separator 15 in the lower portion 10 of the Plate heat exchanger 1 are deposited. About an exit port 16, the condensed moisture particles are then removed.
  • the thus cooled and dried gaseous medium flows after the condensation process via an overflow connection 17 back into the gas-gas heat exchanger. 6
  • an overflow component 18 is arranged, in which overflow areas 19 are formed through which the dried starting gas stream is passed.
  • the Mathströmbauteil 18 is formed by means of a stack 20 of a plurality of plates 21 at which facing side surfaces are connected to each other by means of contact areas.
  • the contact regions include edge contact regions 22 and / or surface contact regions 23, in which, optionally mediated by a suitable bonding agent, for example Lot, the facing side surfaces touch. In this way, a pressure-resistant Kochströmbauteil 18 created.
  • the surface contact regions 23 in particular Sections are used in the central area of the plurality of panels 21 in which the plurality Plates have 21 embossments, so that sections of the imprints adjacent Touch plates.
  • the plate heat exchanger 1 may be lined internally with a suitable material, For example, a plastic which is resistant to the gaseous to be dried Medium is.
  • moist compressed air can be dried which arises in different manufacturing processes.
  • the dried compressed air or dried in other cases gaseous starting medium before leaving of the plate heat exchanger 1 through an output port 8b in the gas-gas heat exchanger 5 in the upward flow by heat transfer from the wet inlet gas stream 7 heated again, so that with the aid of the plate heat exchanger 1 a the process conditions adapted to a predetermined minimum temperature, heated Gas flow can be returned.
