Abstract
The utility model discloses a contraflow heat exchanger for a fuel-fired and gas-fired hot air rotary furnace. The contraflow heat exchanger comprises a burning machine (1) and a heat exchange pipe (2), wherein an inlet (3) and an outlet (4) of the heat exchange pipe are respectively formed at the upper end of the heat exchanger, and the burning machine (1) is arranged at the inlet (3) of the heat exchange pipe. The utility model has a simple, reasonable and compact structure, and has the advantages of longer exchange line of the heat exchanger, longer hot air retention period and remarkable heat energy utilization rate in comparison with the prior art.
Description
Technical field
The utility model relates to fuel oil, combustion gas hot blast revolving burner, particularly, relates to a kind of fuel oil, combustion gas hot blast revolving burner contraflow heat exchanger.
Background technology
Along with socioeconomic fast development, people's living standard improves constantly, and all kinds of leisure food such as bread have entered average family, and bread industry has also arrived fast-developing chance.In a large amount of appearance in the wholesale factory of food, bread chain store and supermarket, the machinery that cures of this employing car load turnover of hot blast revolving burner cures ability efficiently, cures the good advantage of versatility by a large amount of uses curing in the process at products such as French baguette, toast, meal bag, guang-type moon cake, cookie, Denmark's bread, the little meal bag of French, bubble cottonrose hibiscus, heavy oil cakes because of it.
As shown in Figure 1, heat exchanger heat energy load mode schematic diagram for present fuel oil and gas type hot blast revolving burner, as seen this technology has adopted heat energy transmission means from bottom to top, the exit exhaust temperature is higher, explanation still has many heats to be discharged from the exit of heat exchanger when combustor is worked, and has wasted the energy greatly.
Summary of the invention
The purpose of this utility model is, at the problems referred to above, proposes a kind of fuel oil, combustion gas hot blast revolving burner contraflow heat exchanger, the advantage simple with implementation structure, that cost is low, the heat conversion ratio is high.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of fuel oil, combustion gas hot blast revolving burner contraflow heat exchanger comprise combustor and heat-exchange tube, and the import of described heat-exchange tube and outlet are separately positioned on the heat exchanger upper end; Described combustor is arranged at the import department of heat-exchange tube, topmost has been mentioned from foot in the position of the seedling that makes a fire in original technology, make heat exchanger internal combustion hot blast that produces and the wind to be heated that will enter roasted chamber reverse and go, do the temperature difference that can effectively guarantee between the hot and cold air like this and remain on a desirable position, improved exchange heat efficient.
Further, described heat-exchange tube adopts coiled pipe near import one side, increases the heat exchange area of heat exchanger.
Further, described heat-exchange tube adopts straight tube near outlet one side.
Job step:
Fuel oil, when combustion gas hot blast revolving burner contraflow heat exchanger is started working, the hot blast that combustor produced enters heat-exchange tube from import, described hot blast passes through the coiled pipe part from top to bottom, passes through straight-tube portion from bottom to top, discharges from outlet then.Circulated air to be heated in the stove is also carried by circulating fan, and from bottom to top through over-heat-exchanger, these two kinds of hot and cold airs are reverse and go, and make the temperature difference between the hot and cold air remain on a desirable position from start to finish, improved exchange heat efficient greatly.The utility model is simple and reasonable for structure, compact, and the exchange line of heat exchanger increases compared with prior art, and the hot blast time of staying also increases thereupon, and the heat energy rate improves with rate.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As Fig. 2,3,4 is the embodiment schematic diagram of the utility model fuel oil, combustion gas hot blast revolving burner contraflow heat exchanger, comprises combustor 1 and heat-exchange tube 2 as can be seen, and the import 3 of described heat-exchange tube and outlet 4 are separately positioned on the heat exchanger upper end; Described combustor 1 is arranged at import 3 places of heat-exchange tube, topmost has been mentioned from foot in the position of the seedling that makes a fire in original technology, make heat exchanger internal combustion hot blast that produces and the wind to be heated that will enter roasted chamber reverse and go, do the temperature difference that can effectively guarantee between the hot and cold air like this and remain on a desirable position, improved exchange heat efficient.
Described heat-exchange tube 2 adopts coiled pipe near import 3 one sides, has increased the heat exchange area of heat exchanger.Described heat-exchange tube 2 adopts straight tubes near outlet 4 one sides, the hot blast of the similar heat exchanger of the equal volume of comparing the route length overall of process want many more than 20%.
Fuel oil, when combustion gas hot blast revolving burner contraflow heat exchanger is started working, the hot blast that combustor 1 is produced enters heat-exchange tube 2 from import 3, described hot blast passes through the coiled pipe part from top to bottom, passes through straight-tube portion from bottom to top, discharges from exporting 4 then.Circulated air to be heated 8 in the stove is also carried by circulating fan, and from bottom to top through over-heat-exchanger 9, these two kinds of hot and cold airs are reverse and go, and make the temperature difference between the hot and cold air remain on a desirable position from start to finish, improved exchange heat efficient greatly.The utility model is simple and reasonable for structure, compact, and the exchange line of heat exchanger increases compared with prior art, and the hot blast time of staying also increases thereupon, and the heat energy rate improves with rate.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
