Description
Technical field
The present invention relates to a kind of heat-exchanger rig, especially a kind of spiral-plate heat exchanger with three runners.
Background technology
A kind of conventional heat-exchange apparatus of spiral-plate heat exchanger, how spiral-plate heat exchanger of the prior art only has two runners, can not meet some in particular cases needs to the heat exchange simultaneously of three kinds of media, in addition, when cold and hot rate-of flow larger, and ratio is also when large (being greater than 2), and the spiral-plate heat exchanger of common two runners can only meet traffic requirement by strengthening the secondary width of distance between plates or plate.In the time adopting increasing distance between plates to improve rate-of flow, in the body formed process of double helix heat exchange, easily cause spacing column large area to come off because distance between plates is excessive or bending, cause heat exchanger can not meet bearing strength requirement.In the time that employing improves rate-of flow by strengthening the secondary width of plate, in order to ensure heat-transfer effect, need reduce the distance between plates of low discharge medium runner, easily cause the solid particle in low discharge medium that runner is blocked, and cause whole equipment scrapping.CN 1710368A discloses a kind of many spiral-path chasings, this heat exchanger is made up of shell, conveyor screw, sealing and four parts of import and export, the multiple concentric spiral plate that conveyor screw adopts star central division plate (for example bifurcation shape or cross) and quantity to equate with the forking ends of star central division plate forms, on one side surface of every block of spiral plate, be all provided with multiple spaced apart spacing columns or spacing bubble, form the multiple spirality channels that flow through for heat exchanging fluid.Although this many spiral-path chasings have solved runner number problem,, because the length of each runner is identical, when this heat exchanger is under the larger operating mode of cold and hot rate-of flow ratio, heat transfer effect is bad.
Utility model content
The technical problem that utility model will solve is: a kind of three runner spiral-plate heat exchangers are provided, in this three runners spiral-plate heat exchanger, the length of a runner is two other flow channel length sum, in the time that this three runners spiral-plate heat exchanger is used for the two media heat exchange of large flow-rate ratio, just can meet traffic requirement without strengthening the secondary width of distance between plates or plate, good effect of heat exchange, this three runners spiral-plate heat exchanger can also be applicable to three kinds of media be carried out to heat exchange simultaneously.
The technical scheme that technical solution problem is taked: a kind of three runner spiral-plate heat exchangers, comprise housing, in housing, be provided with double helix heat exchange body, the S-type outside curling spiral plate in double helix heat exchange Ti You center forms, between spiral plate, be provided with spacing column, double helix heat exchange body forms the short runner of two equal lengths in housing, on housing periphery and end face, be provided with the short runner import and the short runner exit that are communicated with short runner, described spiral plate is two blocks of sandwich-type spiral plates that equidistant metallic plate forms, between two metallic plates, form a long runner, be provided with long runner suction flange and the long runner exit flange of connection interlayer formula spiral plate two ends runner mouth outward at housing.
As improvement of the present utility model: be provided with in long runner and make two metallic plates that form sandwich-type spiral plate keep equally spaced spacing column.
Beneficial effect: three runner spiral-plate heat exchangers of the present utility model, due in having adopted formed two conventional runners in housing, the sandwich-type spiral plate that adopts described spiral plate to be formed by two equally spaced metallic plates, between two metallic plates, form a long runner, be provided with the long runner suction flange of connection interlayer formula spiral plate two ends runner mouth and the technical characterictic of long runner exit flange outward at housing, between two short runners, increase the long runner that a length is two short flow channel length sums, make the three runner spiral-plate heat exchangers of the present utility model can be for the two media heat exchange of large flow-rate ratio, and just can meet traffic requirement without strengthening the secondary width of distance between plates or plate, good effect of heat exchange, heat exchanger bearing capacity is strong, working stability is reliable, this three runners spiral-plate heat exchanger can also be applicable to three kinds of media be carried out to heat exchange simultaneously, in long runner, be provided with owing to having adopted the technical characterictic that two metallic plates that make to form sandwich-type spiral plate keep equally spaced spacing column, can effectively prevent long runner distortion, further improve the bearing capacity of heat exchanger, made the operation of heat exchanger more stable, reliable, safety.
Brief description of the drawings
Fig. 1 is the cross-sectional view of three runner spiral-plate heat exchangers of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, three runner spiral-plate heat exchangers of the present utility model are described in further detail.
Fig. 1 shows the agent structure of three runner spiral-plate heat exchangers of the present utility model, described three runner spiral-plate heat exchangers comprise housing 1, in housing, be provided with double helix heat exchange body 2, the S-type outwards curling spiral plate 21 in double helix heat exchange Ti You center forms, the curling moulding of double helix heat exchange body is identical with the double helix heat exchange figure modelling in common two runner spiral-plate heat exchangers, between spiral plate, be provided with spacing column, double helix heat exchange body forms the short runner (3 of two equal lengths in housing, 4), on housing periphery and end face, be provided with the short runner import (32 being communicated with short runner, 42) and short runner exit (31, 41), described spiral plate 21 is two blocks of sandwich-type spiral plates that equidistant metallic plate forms, between two metallic plates, form a long runner 22, in long runner, be provided with and make two metallic plates that form sandwich-type spiral plate keep equally spaced spacing column, be provided with long runner suction flange 23 and the long runner exit flange 24 of connection interlayer formula spiral plate two ends runner mouth outward at housing.
Three runner spiral-plate heat exchangers of the present utility model are during for the larger two media heat exchange of flow ratio, large flow medium is assigned in two short runners, low discharge medium is assigned in the long runner between two short runners, in the situation that not increasing the secondary width of distance between plates and plate, just can meet the requirement of large flow medium to flow, meanwhile, also ensure that the residing long runner of low discharge medium has enough distances between plates, prevented that the impurity in low discharge medium from stopping up long runner.In addition, because long flow channel length equals two short flow channel length sums, make low discharge medium can with the abundant heat exchange of large flow medium, heat transfer effect is better.
