Heating is just gradually eliminated due to economy and the reason such as practicality is poor, and although heat-conducting oil heating mode has
The characteristic of high-temperature low-pressure, but there is complex structure in heat-conducting oil heating mode, and auxiliary equipment is more, and conduction oil
Easy decomposition, easy coking, maintenance cost are higher, the shortcomings of go back existence and stability and poor reliability.Tube type hot air
Stove heat is general with coal, oil, gas as fuel, produces high-temperature flue gas, and air is heated by tubular heat exchanger,
This kind of hot-blast stove is the gas of gas one due to heat exchange medium, and the coefficient of heat transfer is relatively low, and this results in hot-blast stove metal consumption
Material amount is high, bulky, and the reason such as the high-temperature oxydation of tubulation, abrasion, overheating deforming and low-temperature corrosion can be led
Pipe break is caused, flue gas and air insertion not only decline heat exchange efficiency, can also pollute, have a strong impact on
What is produced is normally carried out and product quality, or even can cause great to hot air cleaning degree requirement industry higher
Loss.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of heat exchanger for hot-blast stove, its safety
Good, the simple structure of property, heat exchange efficiency is high, and long service life can make full use of the efficient heat transfer of heat pipe
Energy and design feature, improve utilization efficiency of heat energy, realize energy-saving, reduction production cost.
The present invention solve above-mentioned technical problem technical scheme be：Including：Heat pipe (1), radiating fin (2),
Bobbin carriage (3), exhaust gases passes (4) and flange (5)；The heat pipe (1) is made up of two groups of heat pipes, heat pipe
(1) it is horizontally set mode on bobbin carriage (3), axis and the horizontal direction of heat pipe there are certain angle,
Radiating fin on heat pipe (1) tends to plumbness；The evaporator section of heat pipe is arranged on the casing of bobbin carriage (3)
Inside, the radiating segment of heat pipe is the opening radiator structure of naked state in the outside of bobbin carriage (3).
The evaporator section of bobbin carriage (3) gas approach region heat pipe for become length light pipe, bobbin carriage (3) middle part and
The evaporator section of upper area heat pipe is provided with radiating fin, and the radiating segment of the outside heat pipe of bobbin carriage (3) is provided with
Radiating fin.
The both sides of bobbin carriage (3) bottom are respectively arranged with the exhaust gases passes (4) with mounting bracket function,
Exhaust gases passes (4) are connected by flange (5) with combustion furnace.
Bobbin carriage (3) top is additionally provided with the exhanst gas outlet (6) being connected with chimney.
The technical effects of the invention are that：The present invention uses the heat pipe with Thermal conductivity as heat transfer unit
Part, makes full use of the efficient heat transfer performance and its design feature of heat pipe, is rolled up using radiating fin and radiated
Area, realizes enhanced heat exchange, so that fundamentally solve the problems, such as that the gas-gas coefficient of heat transfer is low, therefore can
So that hot-blast stove compact conformation, the reduction of metal consumptive material, volume and weight reduction；Bobbin carriage bottom gas approach area
The evaporator section of domain heat pipe is set to become length light pipe, can reduce the heating surface area of high-temperature area heat pipe, alleviates
The operating pressure of high-temperature area heat pipe, ensures that heat pipe being capable of stable operation；The evaporator section of heat pipe is arranged on bobbin carriage
In vivo, heat pipe heat radiation section forms cold and hot fluid and is separated from each other, solely in the middle of the air outside bobbin carriage
Vertical circulation, the clean hot blast of production, prevents contamination of products；Heat pipe takes horizontally set mode, the axis of heat pipe
With horizontally arranged low-angle inclination angle, the resistance that working medium evaporation is produced with backflow can be reduced, improve heat transfer
Efficiency, while spiral heat dissipation fin can also be made to tend to plumbness, can not only solve radiating fin dust stratification difficult
Topic, and hot air furnace hot air flow path resistance can be reduced, increase the coefficient of heat transfer, improve heat exchange efficiency.This hair
Bright heat-pipe elements are independent working condition, and flue gas and air flow outside pipe, even if certain root heat pipe
The reason rupture such as abrasion, oxidation, corrosion, will not cause to produce a very large impact hot-blast stove.With existing skill
Art is compared, and the present invention also with easy for installation, safeguards simple, and auxiliary equipment is few, and reliability is high, uses the longevity
The advantages of ordering long.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention will be further described.
Accompanying drawing 1 is a kind of heat exchanger schematic diagram for hot-blast stove that the present invention is provided.
