Abstract
A kind of multilayer furnace wall structure of energy-efficient heating furnace.Multilayer furnace wall structure is followed successively by internal layer furnace wall, middle layer furnace wall, outer layer furnace wall from the inside to the outside, and three layers of furnace wall are cylinder-shaped or rectangular.Flue gas baffling block is set on furnace wall.Burner burns in innermost layer furnace wall generates high-temperature flue gas, and high-temperature flue gas rises in internal layer furnace wall, baffling after rising at the top of the furnace wall of middle layer, and high-temperature flue gas downlink and boiler tube between middle layer furnace wall and internal layer furnace wall exchange heat after baffling；Downlink flue gas, in furnace bottom baffling, is risen by middle layer furnace wall bottom space between outer layer furnace wall and middle layer furnace wall, is exchanged heat in uphill process with boiler tube.The utility model has the energy-efficient heating furnace of multilayer furnace wall structure, can greatly improve the leakproofness of furnace body, keeps furnace body operation more stable；Multilayer furnace wall can reduce the radiation loss of furnace body simultaneously.Since boiler tube is not directly by flame impingement, boiler tube is uniformly heated, and medium is not easy coking in boiler tube.
Description
Technical field
The utility model belongs to heating furnace technical field, is related to a kind of multilayer furnace wall structure of energy-efficient heating furnace.
Background technique
Among petrochemical industry process, heating furnace is most basic, essential equipment.Heating furnace is petrochemical industry dress
Important heating equipment, huge energy consumption in setting.Furnace energy consumption is reduced, improving the thermal efficiency has important economic benefit and environmental protection
Benefit.Existing heating furnace radiation chamber is directly washed away by flame mostly, leads to that boiler tube uneven heating is even, easy coking, serious limitation plus
Hot stove continuous operating time shortens heating furnace service life, endangers heating furnace using safe.
Utility model content
The utility model is intended to overcome the shortage of prior art, and provides a kind of multilayer furnace wall efficient energy-saving heating stove.The heating
Furnace good airproof performance, radiation loss is small, heat transfer efficiency is high, is heated evenly, is not easy coking.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of multilayer furnace wall structure of energy-efficient heating furnace, radiation chamber, the convection cell of energy-efficient heating furnace use more
Layer furnace wall structure.Multilayer furnace wall structure is located at furnace interior, and multilayer furnace wall structure is followed successively by internal layer furnace wall 2, middle layer from the inside to the outside
Furnace wall 3, outer layer furnace wall 4, three layers of furnace wall are cylinder-shaped or rectangular.Flue gas baffling block is set on furnace wall.Internal layer furnace wall 2 is in
It is equipped with boiler tube between layer furnace wall 3, between middle layer furnace wall 3 and outer layer furnace wall 4, for exchanging heat.
2 top opening of internal layer furnace wall, bottom is fixed on furnace bottom.
3 top closure of middle layer furnace wall, bottom are fixed on furnace bottom by supporting element 5；Internal layer furnace wall 2 is located at middle layer furnace
Inside wall 3, there are spaces between the two top, for passing through high-temperature flue gas.
4 top closure of outer layer furnace wall, bottom is fixed on furnace bottom；Middle layer furnace wall 3 is located inside outer layer furnace wall 4, and two
There are space between person top, furnace wall 3 bottom end in middle layer is communicated with the space between outer layer furnace wall 4.
Burner 1 is arranged in the energy-efficient heating furnace bottom of multilayer furnace wall, is connected to internal layer furnace wall 2, burner 1 is most interior
Burning generates high-temperature flue gas in layer furnace wall 2, and high-temperature flue gas rises in internal layer furnace wall 2, rolls over after rising to 3 top of middle layer furnace wall
It flows, flue gas downlink and boiler tube between middle layer furnace wall 3 and internal layer furnace wall 2 exchange heat after baffling；Downlink flue gas passes through 3 bottom of middle layer furnace wall
Portion space rises between outer layer furnace wall 4 and middle layer furnace wall 3 in furnace bottom baffling, exchanges heat in uphill process with boiler tube.
The utility model has the following beneficial effects: the utility model has the energy-efficient heating furnace of multilayer furnace wall structure, energy
The leakproofness for enough greatly improving furnace body keeps furnace body operation more stable；Multilayer furnace wall can reduce the radiation loss of furnace body simultaneously.By
In boiler tube not directly by flame impingement, boiler tube is uniformly heated, and medium is not easy coking in boiler tube.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model；
In figure: 1 burner；2 internal layer furnace walls；3 middle layer furnace walls；4 outer layer furnace walls；Supporting element 5.
Specific embodiment
Below in conjunction with technical solution and attached drawing, in detail narration specific embodiment of the utility model.
A kind of multilayer furnace wall structure of energy-efficient heating furnace, radiation chamber, the convection cell of energy-efficient heating furnace use more
Layer furnace wall structure.Multilayer furnace wall structure is followed successively by internal layer furnace wall 2, middle layer furnace wall 3, outer layer furnace wall 4 from the inside to the outside, and three layers of furnace wall are equal
To be cylinder-shaped or rectangular, three is concentric in arbitrary cross section.Between internal layer furnace wall 2 and middle layer furnace wall 3, middle layer furnace wall 3 and outer layer
Boiler tube is equipped between furnace wall 4, for exchanging heat.
