The tail gas residual heat recycling device comprises a plurality of heat transfer plates, longitudinal baffle plates and transverse baffle plates, wherein trough-shaped concave holes and crest-shaped convex peaks are formed by stamping on the front sides and the back sides of the heat transfer plates respectively; the trough-shaped concave holes and the crest-shaped convex peaks are formed longitudinally and transversely at certain intervals; the heat transfer plates are overlapped at certain intervals in the thickness direction, thereby forming odd interval spaces and even interval spaces; the longitudinal baffle plates are arranged on both longitudinal sides of the odd interval spaces; the transverse baffle plates are arranged on both transverse sides of the even interval spaces, thereby forming longitudinal flow channels and transverse flow channels which are formed longitudinally at certain intervals in a staggered way. The heat energy recycling effect of the residual heat recycling device is improved. Compared with the prior art, the tail gas residual heat recycling device has the advantages that the flow channel resistance is not increased, and the heat transfer efficiency is increased without increasing extra energy consumption.

Description

A kind of exhaust waste heat recovery device for drying equipment
Technical field
The utility model relates to waste-heat recovery device, particularly relates to a kind of exhaust waste heat recovery device for drying equipment.
Background technology
The core component of waste-heat recovery device is heat transfer zone wherein.Shell and tube and board-like heat transfer structure are applied more in waste-heat recovery device at present.Board-like heat transfer structure conducts heat by plate face, by the structure difference of heat transfer plate, can be divided into plate armature, spiral plate structure, plate-fin structure etc.The waste-heat recovery device of board-like heat transfer structure is mainly used in the place that pressure medium is not high, has that heat transfer efficiency is high, heat loss is little, a feature such as advantages of compact and light structure, floor space are little, easy to clean is installed, be widely used, long service life.The high 3-5 of its ratio of heat transfer coefficient shell and tube heat transfer structure doubly.
In the waste-heat recovery device of drying equipment, the waste-heat recovery device application of plate-fin structure is more.Plate-fin structure adopts the mode of dull and stereotyped stack, and the fin of corrugated is set between flat board and flat board.In this board-like heat transfer structure, corrugated fin has increased heat transfer area.But in mobile in the passage that the defect of this structure is fluid to be formed at corrugated fin, corrugated fin can not obviously promote the turbulence of fluid, and this has affected the heat-transfer effect of fluid greatly.
Summary of the invention
The purpose of this utility model is a kind of exhaust waste heat recovery device for drying equipment of design, to promote the energy recovery effect of waste-heat recovery device.
In order to achieve the above object, the technical scheme of employing of the present utility model is: a kind of exhaust waste heat recovery device for drying equipment, it is characterized in that it comprises several heat transfer plates, longitudinal baffle and transverse baffle, at described heat transfer plate just, on anti-two sides, be respectively equipped with trough shape shrinkage pool and the protruding peak of crest shape that punching press forms, described trough shape shrinkage pool and the protruding peak of described crest shape are spaced on described heat transfer plate, form the fluctuating shape medium runner of crisscross shape, described heat transfer plate thickness direction at regular intervals distance be arranged under the overlay, form odd number clearance space and even number clearance space, described longitudinal baffle is arranged on longitudinal both sides of described odd number clearance space, described transverse baffle is arranged on the both lateral sides of described even number clearance space, make described odd number clearance space and the each self-forming way flow of even number clearance space road, thereby in formation, staggered spaced apart longitudinal runner and transverse flow channels down.
The utility model is in order to make gas in turbulent flow optimum state, strengthen heat-transfer effect, technique scheme is further arranged: the spacing between described heat transfer plate is upper and lower is 11-13mm, the distance that the protruding peak of crest shape and trough shape shrinkage pool depart from plate benchmark is 7-10mm, and the spacing of the protruding peak of crest shape and trough shape shrinkage pool is 40-44mm.
Compared with prior art, the beneficial effect having is the utility model:
On heat transfer plate, the contoured trough shape shrinkage pool of crisscross shape and the protruding peak of crest shape have increased heat transfer area effectively, and trough shape shrinkage pool and the protruding peak of crest shape increased the turbulence of gas in runner, make gas in turbulence state, have strengthened heat-transfer effect.
Compared with plate-fin heat transfer structure, flow passage resistance force of waterproof of the present utility model does not increase, and therefore in improving heat transfer efficiency, does not increase extra energy consumption.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is that trough shape shrinkage pool and the protruding peak of crest shape arrange schematic diagram on heat transfer plate.
Fig. 2 is the profile of the present embodiment with A-A direction in Fig. 1.
Fig. 3 is the profile of the present embodiment with B-B direction in Fig. 1.
Fig. 4 is the planform reference diagram at the protruding peak of crest shape of capable of meeting requirements on three-dimensional gauss of distribution function.
Detailed description of the invention
As shown in Figure 1, this figure only represents that trough shape shrinkage pool 4 and the protruding peak 3 of crest shape arrange schematic diagram on heat transfer plate 1.Heat transfer plate 1 is divided into multiple rectangular areas, wherein shows that the position of "+" represents the position at place, the protruding peak of crest shape, shows that the position of "-" represents the position at trough shape shrinkage pool place.The protruding peak of crest shape is identical with the shape of trough shape shrinkage pool, and opposite direction, is spaced.
As Fig. 2, shown in Fig. 3, the present embodiment comprises several heat transfer plates 1, longitudinal baffle 2 and transverse baffle 5, at described heat transfer plate 1 just, on anti-two sides, be respectively equipped with trough shape shrinkage pool 4 and the protruding peak 3 of crest shape that punching press forms, described trough shape shrinkage pool 4 and the protruding peak 3 of described crest shape are spaced on described heat transfer plate 1, form the fluctuating shape medium runner of crisscross shape, described heat transfer plate 1 thickness direction at regular intervals distance be arranged under the overlay, form odd number clearance space 9 and even number clearance space 8, described longitudinal baffle 2 is arranged on longitudinal both sides of described odd number clearance space 9, described transverse baffle 5 is arranged on the both lateral sides of described even number clearance space 8, make described odd number clearance space 9 and the each self-forming way flow of even number clearance space 8 road, thereby in formation, staggered spaced apart longitudinal runner 7 and transverse flow channels 6 down, the logical hot blast of transverse flow channels 6, the longitudinally logical cold wind of runner 7.
As shown in Figure 4, the shape and structure capable of meeting requirements on three-dimensional gauss of distribution function of the protruding peak of crest shape and trough shape shrinkage pool, the protruding peak of crest shape that punching press forms and trough shape shrinkage pool have effectively increased the distance of medium circulation, increase the heat transfer time, increase turbulence when media flow, and smooth convex surface and concave can reduce the resistance of medium circulation.
