Definitions

  • the present invention relates to a plate beat exchanger for three fluids, and more particularly to a plate heat exchanger for three fluids, which allows a first fluid to exchange heat with a second fluid, and then with a third fluid, and also to a method for producing the heat exchanger.
  • a preceding-stage heat exchange section 13A having interplate first fluid paths f1 for passing a first fluid La between the plates 15 and interplate second fluid paths f2 for passing a second fluid Lc between the plates 15 is formed at one side in a plate longitudinal direction of a plate laminate composed of many plates 15 laminated one on another.
  • the interplate first fluid paths f1 and the interplate second fluid paths f2 are positioned alternately in a plate laminating direction.
  • a succeeding-stage heat exchange section 13B having interplate first fluid paths f1 continued from the interplate first fluid paths f1 in the preceding-stage heat exchange section 13A and adapted to pass the first fluid La between the plates 15 and interplate third fluid paths f3 for passing a third fluid Lb between the plates 15 is formed at the other side in the plate longitudinal direction of the plate laminate.
  • the interplate first fluid paths f1 and the interplate third fluid paths f3 are positioned alternately in the plate laminating direction (see Japanese laid-open Patent Publication No. 9-60996).
  • the heat exchanger has a structure in which the preceding-stage heat exchange section 13A for exchanging heat between the first fluid La and the second fluid Lc, and the succeeding-stage heat exchange section 13B for exchanging heat between the first fluid La and the third fluid Lb are located parallel in the longitudinal direction of the plates 15 and integrated together.
  • Such a conventional structure can make the entire heat exchanger considerably compact in comparison with the preceding-stage heat exchange section 13A and the succeeding-stage heat exchange section 13B being composed of separate plate heat exchangers.
  • the conventional heat exchanger still has room for improvement in view of the fact that further downsizing of the equipments and further energy saving have been demanded in recent years.
  • the present invention has been made in view of the above drawbacks. It is therefore an object of the present invention mainly to ensure further compactness and achieve a further decrease in a heat loss, by adopting a rational structure in integrating the preceding-stage heat exchange section and the succeeding-stage heat exchange section.
  • FIG. 1 shows a schematic structure of an absorption refrigerating machine, in which the reference numeral 1 denotes a high temperature regenerator, 2 a low temperature regenerator, 3 a condenser, 4 an evaporator, and 5 an absorber.
  • a low concentration absorption solution La e.g., an aqueous solution of lithium bromide
  • a refrigerant R e.g., water
  • An intermediate concentration absorption solution Lb from which the refrigerant R has been separated in the high temperature regenerator 1 is sent to the low temperature regenerator 2 via a passage r1.
  • a refrigerant vapor R' generated in the high temperature regenerator 1 is sent as a heat source to a low temperature heater 7 in the low temperature regenerator 2 via a passage r2.
  • the intermediate concentration absorption solution Lb is heated by the refrigerant vapor R' as a heat source which has been generated in the high temperature regenerator 1, for thereby further evaporating and separating the refrigerant R from the intermediate concentration absorption solution Lb.
  • the refrigerant vapor R' generated in the low temperature regenerator 2 and the refrigerant vapor R' which has been used as a heat source in the low temperature heater 7 are cooled by a cooler 8 in the condenser 3 to be condensed.
  • the condensed refrigerant R i.e., a liquid refrigerant
  • the condensed refrigerant R sent from the condenser 3 is sprayed onto an interior heat exchanger 11 by a sprayer 10, while the refrigerant R is being circulated by a refrigerant pump 9A, for thereby cooling a fluid C to be cooled (e.g., water or brine) flowing in the interior heat exchanger 11 by evaporating the refrigerant R and utilizing the heat of vaporization thereof.
  • a fluid C to be cooled e.g., water or brine
  • a high concentration absorption solution Lc from which the refrigerant R has been separated in the low temperature regenerator 2 is sent to the absorber 5 via a passage r4.
  • the high concentration absorption solution Lc sent from the low temperature regenerator 2 is sprayed by a sprayer 12, and hence absorbs the refrigerant vapor R' generated in the evaporator 4, forming a low pressure atmosphere for evaporating the sprayed refrigerant R at a low temperature in the evaporator 4.
  • the low concentration absorption solution La which has absorbed the refrigerant vapor R' in the absorber 5 is returned to the high temperature regenerator 1 via a passage r5 by a solution pump 9B, and the step of separating the refrigerant R from the low concentration absorption solution La is conducted again.
  • the reference numeral 13 denotes a heat recovery type heat exchanger for allowing the low concentration absorption solution La having a low temperature which is to be returned to the high temperature regenerator 1 to exchange heat with the high concentration absorption solution Lc having an intermediate temperature which is to be sent from the low temperature regenerator 2 to the absorber 5, and then to exchange heat with the intermediate concentration absorption solution Lb having a high temperature which is to be sent from the high temperature regenerator 1 to the low temperature regenerator 2, for thereby recovering the heat that the high concentration absorption solution Lc and the intermediate concentration absorption solution Lb hold.
  • the heat recovery type heat exchanger 13 is shown only schematically to describe the order of heat exchange of the low concentration absorption solution La with the high concentration absorption solution Lc and the intermediate concentration absorption solution Lb, and does not correspond with its concrete structure to be described later on.
  • the reference numeral 14 denotes a cooler for removing the heat of absorption generated at the time when the sprayed absorption solution Lc in the absorber 5 absorbs the refrigerant.
  • a cooling fluid W e.g., cooling water circulated into a cooling tower
  • W is supplied to the cooler 14 in the absorber 5 and the cooler 8 in the condenser 3.
  • the heat recovery type heat exchanger 13 for exchanging heat among three fluids i.e., the low concentration absorption solution La, the high concentration absorption solution Lc, and the intermediate concentration absorption solution Lb (hereinafter respectively referred to as a first fluid, a second fluid, and a third fluid), is constructed in the following manner:
  • a plate 15 has a corrugated cross-sectional shape, except its portions near both ends thereof, and has holes p1 to p4 for inlet and outlet path at corners thereof.
  • a plurality of the plates 15 are laminated in such a state that the ridges of the corrugations of the plates 15 are contacted with those of the facing plates.
  • FIG. 1 the low concentration absorption solution La
  • Lc high concentration absorption solution
  • Lb intermediate concentration absorption solution Lb
  • a preceding-stage heat exchange section 13A for exchanging heat between the first fluid La and the second fluid Lc is formed at one side of the plate laminate in a plate laminating direction.
  • a succeeding-stage heat exchange section 13B for exchanging heat between the first fluid La which has exchanged heat with the second fluid Lc in the preceding-stage heat exchange section 13A and the third fluid Lb is formed at the other side of the plate laminate in the plate laminating direction.
  • interplate first fluid paths f1 for passing the first fluid La between the adjacent plates 15 and interplate second fluid paths f2 for passing the second fluid Lc between the adjacent plates 15 are positioned alternately in the plate laminating direction. While these fluids are passing through these interplate fluid paths f1 and f2, heat is exchanged between the first fluid La and the second fluid Lc via the plates 15 serving as heat transfer walls.
  • interplate first fluid paths f1 for passing the first fluid La between the adjacent plates 15 and interplate third fluid paths f3 for passing the third fluid Lb between the adjacent plates 15 are positioned alternately in the plate laminating direction. While these fluids are passing through these interplate fluid paths f1 and f3, heat is exchanged between the first fluid La and the third fluid Lb via the plates 15 serving as heat transfer walls.
  • the interplate fluid paths f1 to f3 are finely divided into many segments in the plate width direction perpendicular to the fluid flowing direction. Thus, a larger area of heat transfer can be ensured, and high strength can be obtained.
  • each plate 15 near both ends thereof are in the form of a flat plate without corrugations, headers for the passages finely divided in the plate width direction are formed at both end portions of the interplate fluid paths f1 to f3.
  • the holes p1 among the holes p1 to p4 for inlet and outlet path formed at the four corners of the respective plates 15 constitute a first fluid crossover path m which extends between the headers beside one end of the interplate first fluid paths f1 in the preceding-stage heat exchange section 13A and the headers beside one end of the interplate first fluid paths f1 in the succeeding-stage heat exchange section 13B inside the plate laminate.
  • FIG. 2 represents a vertical cross-sectional view of the heat exchanger 13 with overlaps of these flow paths being developed.

  • the hole p2 further constitutes a third fluid outlet path o3 which extends between headers beside the one end of the interplate third fluid paths f3 in the succeeding-stage heat exchange section 13B inside the plate laminate.
  • the neck d of the hole p2 extends to the corresponding hole p2 of the next plate 15 in the lamination of the plates 15, and hence each of communications is blocked between the second fluid inlet path i2 and the interplate first fluid paths f1, and between the third fluid outlet path o3 and the interplate first fluid paths f1.
  • the remaining hole p3 constitutes a second fluid outlet path o2 which extends between the headers beside the other end of the interplate second fluid paths f2 in the preceding-stage heat exchange section 13A inside the plate laminate, and constitutes a third fluid inlet path i3 which extends between the headers beside the other end of the interplate third fluid paths f3 in the succeeding-stage heat exchange section 13B inside the plate laminate.
  • the neck d of the hole p3 of the plate 15 extends to the corresponding hole p3 of the next plate 15 in the lamination of the plates 15, as in the case of the other inlet and outlet paths, and hence each of communications is blocked between the second fluid outlet path o2 and the interplate first fluid paths f1, and between the third fluid inlet path i3 and the interplate first fluid paths f1.
  • the first fluid La flows as parallel streams from the first fluid inlet path i1 into a plurality of the interplate first fluid paths f1 in the preceding-stage heat exchange section 13A. Subsequently, the first fluid La having passed as parallel streams through a plurality of the interplate first fluid paths f1 in the preceding-stage heat exchange section 13A is gathered at the first fluid crossover path m, and then flows as parallel streams into a plurality of the interplate first fluid paths f1 in the succeeding-stage heat exchange section 13B. Then, the first fluid La having passed as parallel streams through a plurality of the interplate first fluid paths f1 in the succeeding-stage heat exchange section 13B is discharged in a gathered state from the first fluid outlet path o1.

  • the second fluid Lc having passed through a plurality of the interplate second fluid paths f2 as parallel streams is discharged in a gathered state from the second fluid outlet path o2, and hence the first fluid La (low concentration absorption solution) exchanges heat with the second fluid Lc (high concentration absorption solution) as countercurrent flows at a plurality of the paths in the preceding-stage heat exchange section 13A.
  • the third fluid Lb flows from the third fluid inlet path i3 into a plurality of the interplate third fluid paths f3 as parallel streams.
  • the third fluid Lb having passed through a plurality of the interplate third fluid paths f3 as parallel streams is discharged in a gathered state from the third fluid outlet path o3, and hence the first fluid La (low concentration absorption solution) which has exchanged heat with the second fluid Lc (high concentration absorption solution) in the preceding-stage heat exchange section 13A exchanges heat with the third fluid Lb (intermediate concentration absorption solution) as countercurrent flows at a plurality of the paths in the succeeding-stage heat exchange section 13B.
