Abstract
The invention relates to a chamfered air extracting opening device of a plate-fin type heat exchanger in a main heat exchanger. The chamfered air extracting opening device comprises a plate bundle body, wherein the plate bundle body comprises a clapboard, fins, seal strips and flow deflectors, and two ends of the clapboard on two sides of the plate bundle body are fixedly connected with the upper end of a fluid inlet and the lower end of a fluid outlet respectively; the flow deflectors are arranged at the upper end and the lower end of the clapboard, the section of each flow deflector is triangular, the two flow deflectors are symmetrically arranged at the upper end and the lower end of the clapboard and are integrally rectangular, and through openings of the flow deflectors at the upper end and the lower end of the clapboards are respectively a guiding outlet and a guiding inlet and respectively correspond to the fluid outlet and the fluid inlet. Through the structure of the invention, a traditional wide flow deflector type is improved; and the area occupied by the whole flow deflectors is reduced and the area occupied by the fins is increased under the same input and output resistance conditions, thus the heat exchange area of a whole heat exchanger in unit volume is increased.
Description
Technical field
The present invention relates to a kind of interchanger air and take out a mouthful device, relate in particular in a kind of main heat exchanger plate fin type heat exchanger hypotenuse air and take out a mouthful device.
Background technology
Plate fin type heat exchanger is since producing; Just since its specific area big, have numerous advantages such as secondary heating surface, heat transfer efficiency height, compact conformation, volume are little, in light weight; And be widely used in industrial departments such as Aero-Space, refrigeration, petrochemical industry, dynamic power machine and superconduction, be considered to one of the most rising novel heat-exchange apparatus.At present, the main heat exchanger of air separation plant adopts this structure more.
Main heat exchanger mainly provides the place that air, pressurized air and oxygen, nitrogen and dirty nitrogen carry out heat exchange; Pass through main heat exchanger; Air is cooled to and approaches the low-temperature liquefaction temperature, then gets into rectifying column, flows out ice chest after oxygen, nitrogen and dirty nitrogen are heated to normal temperature.Therefore the structural shape of main heat exchanger is vital to the influence of whole air separation unit.
Plate-fin heat exchanger is that plate bundle body is equipped with compositions such as necessary end socket, adapter, supporting.And the plate bundle is made up of dividing plate, fin, strip of paper used for sealing, flow deflector; Between adjacent two dividing plates, place fin, flow deflector and strip of paper used for sealing and form an interlayer; Be called passage; Such interlayer is stacked according to the different modes of fluid, soldering just composing plate in aggregates bundle, the plate bundle is the core of plate-fin heat exchanger.Strip of paper used for sealing, dividing plate, fin are numerous in the effect of plate Shu Tizhong, all play important effect.Wherein flow deflector then plays guiding and imports and exports the fluid that the caliber end socket flows into the plate bundle, makes it to be uniformly distributed in the effect of runner, or compiling the fluid that flows out from runner makes it to be discharged by outlet through end socket.Fin then is the basic heat exchange element in the main heat exchanger, and its heat transfer area is approximately 67% ~ 88% of whole heat exchanger total heat conduction area, and the heat that plays a part to strengthen between adjacency channel transmits, and the heat-transfer effect of flow deflector can be ignored than fin.Therefore, if the flow deflector area occupied is excessive, then can cause the heat exchange area of whole heat exchanger to reduce.
Appear at the heat exchanger middle part through regular meeting in the main heat exchanger; A kind of fluid goes out; The situation that one other fluid is advanced, flow deflector width generally speaking is wide, will take into account the resistance problem of outlet simultaneously; The width of single flow deflector again can not be narrow, therefore has the loss of its heat exchange area of heat exchanger of importing and exporting bigger midway.
Summary of the invention
The present invention seeks to provide in a kind of main heat exchanger plate fin type heat exchanger hypotenuse air to take out a mouthful device for the deficiency that overcomes prior art; Can original wide flow deflector pattern be improved; Under identical import and export resistance condition; Reduce the shared area of whole flow deflector, strengthened the fin area occupied, thereby improved the heat exchange area of whole heat exchanger in the unit volume.
For achieving the above object; The technical scheme that the present invention adopts is: plate fin type heat exchanger hypotenuse air is taken out a mouthful device in a kind of main heat exchanger; Comprise plate bundle body, end socket, adapter, supporting etc. are installed, said plate bundle body bag dividing plate, fin, strip of paper used for sealing, flow deflector on the plate bundle body; Place fin, flow deflector and strip of paper used for sealing between adjacent two dividing plates and form an interlayer; Stacked and the soldering just composing plate in aggregates bundle body of a plurality of interlayer different modes, on plate bundle body two side positions, run through each layer channel unit along X-direction and offer that fluid enters the hole and fluid portals, the two ends of dividing plate are connected fixing with the upper end that fluid enters the hole with the lower end that fluid portals respectively;
Said dividing plate upper and lower side is equipped with flow deflector; The cross section of said flow deflector is triangular form; Two flow deflectors are symmetricly set on dividing plate upper and lower side and whole rectangular; The port of the flow deflector of said dividing plate upper and lower side is respectively diversion outlet and water conservancy diversion import, and it is corresponding that said diversion outlet and fluid portal, and it is corresponding that water conservancy diversion import and fluid enter the hole.
Preferably, the length of said flow deflector is identical with the width of fin.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Plate fin type heat exchanger hypotenuse air is taken out a mouthful device in a kind of main heat exchanger of the present invention program, has saved the shared area of flow deflector, has strengthened the fin area occupied, thereby has improved the heat exchange area of whole heat exchanger in the unit volume.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is taken out the preferable structural representation of mouthful device for plate fin type heat exchanger hypotenuse air in the main heat exchanger of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
Said dividing plate 2 upper and lower sides are equipped with flow deflector 5; The cross section of said flow deflector 5 is triangular form; Two flow deflectors 5 are symmetricly set on dividing plate 2 upper and lower sides and whole rectangular, and the length of flow deflector 5 is identical with the width of fin 3, and the port of the flow deflector 5 of said dividing plate 2 upper and lower sides is respectively diversion outlet and water conservancy diversion import; It is 6 corresponding that said diversion outlet and fluid portal, and it is corresponding that water conservancy diversion import and fluid enter hole 7.
Plate fin type heat exchanger hypotenuse air is taken out a mouthful device in a kind of main heat exchanger of the present invention program, has improved the excessive problem of flow deflector area occupied; Improved the heat exchange area in the unit volume; Can be easier to satisfy the requirement of resistance drop.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the present invention, all drop within the rights protection scope of the present invention.
