Description
The utility model relates to a kind of industrial heat hot wind furnace.
Hot-blast stove is the capital equipment of industry heating.Yet in present widely used industrial hot-blast stove, because employing is the combustion chamber and the three backhaul heat transfer types of cylindrical structural, therefore, the general thermal efficiency is all lower, approximately only is about 50%.In addition, this hot-blast stove is not owing to add waste-heat recovery device and temperature tunable arrangement, thereby thermal loss is more serious, and temperature regulating range is very little, and the scope of application is very restricted.
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of rational in infrastructure, thermal efficiency height, good energy-conserving effect, and the wider negative pressure adjustable high-efficiency energy-saving hot blast furnace of the scope of application.
For achieving the above object, the utility model has been taked following measure: the structure of 1, improving the combustion chamber, the Combustion chamber design of hot-blast stove is become the unequal section bottleneck structure, so not only make fuel in the combustion chamber, to be fully burned, and improved the furnace temperature and the thermal efficiency effectively.2, penetrate the principle of convection current forced friction heat exchange according to two revolution width of cloth, in the heat convection chamber, added the spirality flow deflector, the air-flow that enters in the heat convection chamber is carried out mandatory friction heat exchange, to improve its thermal conversion efficiency.3, added the UTILIZATION OF VESIDUAL HEAT IN retracting device.Improved utilization rate of waste heat.4, set up air intake adjusting device.The user can select different air quantity and temperature for use according to different working conditions, thereby has reached the purpose that enlarges its scope of application.
Specific embodiments of the present utility model is as shown in drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that A-A of the present utility model is to schematic diagram
Fig. 3 is the structural representation of the utility model waste-heat recovery device
Fig. 4 is the structural representation that the utility model adopts the top air intake
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
Negative pressure adjustable high-efficiency energy-saving hot blast furnace includes parts such as body of heater 1, air-intake device 2, UTILIZATION OF VESIDUAL HEAT IN retracting device 3, chimney 4, smoking machine 5, warm-air pipe 6.Be provided with combustion chamber 7 and heat convection chamber 8 in the body of heater 1.The combustion chamber adopts refractory material to make, and it is shaped as the bottleneck structure of unequal section.Bottom in the combustion chamber is provided with grate 11.Heat convection chamber 8 cylindrical structures, and adopt heat conductivility good metal material to make.In order to make the air-flow that enters in the heat convection chamber obtain forced friction heat exchange effect, in heat convection chamber 8, be provided with spiral flow deflector 9.For ease of removing flue dust, the bottom in the heat convection chamber that is connected with smoke discharge pipe is provided with flue dust cleaning hole 10.The air-intake device 2 of hot-blast stove has two kinds of versions, and a kind of is side air inlet; Another kind is the top air intake.On side air inlet or top air-intake device, be provided with volume damper 12.By volume damper 12, can be effectively changing intake and temperature, to adapt to the needs of different operating modes.
UTILIZATION OF VESIDUAL HEAT IN retracting device 3 is arranged between body of heater 1 and the smoking machine 5.UTILIZATION OF VESIDUAL HEAT IN retracting device 3 is made of the columniform sleeve pipe of bilayer.Inner sleeve 13 is a smoke discharge pipe, and inner sleeve 13 constitutes air-inlet cavity 16 with outer tube 14.For the effect that can make the air-flow that enters in the air-inlet cavity 16 and the high-temperature flue gas in the smoke discharge pipe reach the forced friction heat exchange, at inner sleeve 13(smoke discharge pipe) outer rim be provided with spirality flow deflector 15.Like this, not only reduced the exhaust gas temperature in the smoke exhaust pipe effectively, eliminated of the harm of high temperature exhaust gas temperature, and effectively utilized the waste heat of smoke evacuation, improved EAT and heat energy utilization rate smoking machine.
Working method of the present utility model is to produce realization like this: the high-temperature flue gas in the combustion chamber 7 is under the effect of smoking machine, produce negative pressure, enter heat convection chamber 8(IV from the combustion chamber through A, B, three floss holes of C), and enter heat convection chamber 8(II) through floss hole D, motion along clockwise direction then, the inner sleeve 13(flue gas exhaust that enters UTILIZATION OF VESIDUAL HEAT IN retracting device 3 from exhaust opening is put pipe), through smoking machine 5, from chimney 4, discharge.Air intake gas is the air-inlet cavity from the UTILIZATION OF VESIDUAL HEAT IN retracting device 16 then, after the heat exchange of UTILIZATION OF VESIDUAL HEAT IN retracting device convection current forced friction, enter the heat convection chamber 8(I in the body of heater) in, and motion in the counterclockwise direction, enter heat convection chamber 8(III successively) and the 8(V), in heat convection chamber 8(I, III, V) in carry out two revolution width of cloth and penetrate after the heat exchange of convection current forced friction, after warm-air pipe 6 sucking-offs.Flue dust in the heat convection chamber then can be discharged by cleaning hole 10.
11 of volume dampers that are arranged on the air-intake device 2 can carry out step-less adjustment to temperature according to the requirement of operating mode.
The utility model novel structure, rationally, thermal efficiency height, good energy-conserving effect, air quantity, temperature can be regulated arbitrarily according to operating mode, are in a kind of being suitable for, the desirable industry heating facility of the various operating modes of low temperature.
