Technical field
The utility model relates to a kind of heat exchanger, is specifically related to a kind of burner hearth multi-stage heat exchanger.
Background technology
Heat exchanger is the process equipment carrying out heat transmission, and it is widely used in oil refining, petrochemical industry and the industry of other vague generalization.Such as cooling, condensation, heating, evaporation and Waste Heat Recovery etc.Heat exchanger, due to the diversity (corrosivity, temperature, pressure, medium, impurity, heat exchange amount etc.) of service condition, also needs rational structure and form.
Nowadays, the heat exchanger for hearth of hot-blast stove is arranged unreasonable due to flue gas backhaul and extraneous cold wind backhaul, causes heat-shift not too fully to cause heat lose greatly and waste; Flue gas through heat exchange directly enters in air without filtration treatment, contaminated environment; Heat exchange pipeline in use for some time, is retained in pipeline and is had lime-ash, be difficult to cleaning; Adopt the heat exchanger of single backhaul design, cold air and the smoke contacts time short, cause heat exchange insufficient.
Summary of the invention
For above-mentioned problem, the utility model provides a kind of burner hearth multi-stage heat exchanger, and this device can improve the heat exchange efficiency of heat exchanger, reduces environmental pollution, reduces production cost, is easy to clear up heat exchange pipeline.
The technical solution of the utility model is:
A kind of burner hearth multi-stage heat exchanger, comprise cylindrical shell, cylindrical shell both sides are respectively equipped with cold wind import and hot-blast outlet, at least two upper smoke box and two lower smoke box are provided with in described cylindrical shell, first order upper smoke box side is provided with gas approach, described upper smoke box is communicated with lower smoke box by many heat exchange pipelines, afterbody lower smoke box side is provided with exhanst gas outlet, several dividing plates are set between described heat exchange pipeline, described upper smoke box top is provided with smoke box door, lower smoke box is provided with cleaning door, and described heat exchange pipeline is provided with heat exchange fin.
Above-mentioned, heat exchange pipeline is divided into multiple chamber by dividing plate, forms the air channel that S shape is bending.
Above-mentioned, heat exchange fin is spirally wound on heat exchange pipeline periphery along the direction of heat exchange pipeline length.
Preferably, cold wind import is provided with air filter.
Preferably, exhanst gas outlet is provided with air filter.
The beneficial effects of the utility model are:
Arrange several dividing plates between the utility model heat exchange pipeline, heat exchange pipeline is divided into a few part by dividing plate, forms the air channel that S shape is bending, extends heat exchange distance, makes heat exchange more abundant, improves heat exchange efficiency; Cold wind import is provided with air filter, treats that the air of heat exchange carries out dust removal and filtration for suction, decreases the dust that air brings into and is attached on heat exchange pipeline wall, affect heat transfer effect; Exhanst gas outlet is provided with air filter, decreases the pollution of waste gas to environment; Due to the raising of heat exchange efficiency, decrease the input of fuel, production cost is reduced; Upper smoke box top is provided with smoke box door and lower smoke box is provided with cleaning door, makes heat exchange pipeline be easy to cleaning, and cleaning thoroughly; Heat exchange pipeline is provided with heat exchange fin, increases heat exchange area.
Accompanying drawing explanation
Fig. 1 is one of structural representation of the present utility model;
Fig. 2 position structural representation two of the present utility model.
Meaning in figure representated by sequence number is: 1. cylindrical shell, 2. cold wind import, 3. hot-blast outlet, 4. upper smoke box, 5. lower smoke box, 6. gas approach, 7. heat exchange pipeline, 8. exhanst gas outlet, 9. dividing plate, 10. smoke box door, 11. cleaning doors, 12. heat exchange fins, 13. chambers.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment one: shown in Figure 1, a kind of burner hearth multi-stage heat exchanger, comprise cylindrical shell 1, cylindrical shell 1 both sides are respectively equipped with cold wind import 2 and hot-blast outlet 3, two upper smoke box 4 and two lower smoke box 5 are provided with in described cylindrical shell 1, first order upper smoke box side is provided with gas approach 6, described upper smoke box 4 is communicated with lower smoke box 5 by many heat exchange pipelines 7, lower smoke box side, the second level is provided with exhanst gas outlet 8, several dividing plates 9 are set between described heat exchange pipeline 7, described upper smoke box 4 top is provided with smoke box door 10, lower smoke box 5 is provided with cleaning door 11, heat exchange pipeline 7 is made to be easy to cleaning, and cleaning thoroughly, described heat exchange pipeline 7 is provided with heat exchange fin 12.
Above-mentioned, heat exchange pipeline 7 is divided into multiple chamber 13 by dividing plate 9, forms the air channel that S shape is bending, extends heat exchange distance, add the time of contact of cold wind and heat exchange pipeline 7, make heat exchange more abundant.
Above-mentioned, heat exchange fin 12 is spirally wound on heat exchange pipeline 7 periphery along the direction of heat exchange pipeline 7 length, adds heat exchange area.
Preferably, cold wind import 2 is provided with air filter, treats that the air of heat exchange carries out dust removal and filtration for suction, decreases the dust that air brings into and is attached on heat exchange pipeline 7 wall, affect heat transfer effect.
