Abstract
The utility model relates to an air preheating device, and belongs to the technical field of heat energy conversion devices. The air preheating device utilizing boiler smoke heat sufficiently comprises a barrel. A smoke inlet is arranged at the upper end of the barrel, a smoke outlet is arranged at the lower end of the barrel, a heat exchange tube is arranged in the barrel, an air inlet box and an air outlet box are arranged on one side of the barrel respectively, an air inlet hole is connected on the air inlet box, an air outlet is connected on the air outlet box, a middle box body is arranged on the other side of the barrel, and the barrel and the heat exchange tube are made of carbon steel or stainless steel. By adopting a horizontal type structure wholly, the air preheating device is very convenient to utilize the heat of smoke sufficiently, and is more convenient to be maintained in daily life, and thus the working performance is improved, the maintenance cost of an enterprise is reduced, and the economic benefits of the enterprise are improved.
Description
Technical field
The utility model relates to the air preheating apparatus, belongs to the thermal energy conversion device technical field.
Background technology
At present, the flue-gas temperature that boiler is discharged is all higher, in order to utilize the heat of smoke evacuation; Big city is provided with cooling water heater or air heater on boiler, the temperature of water or air is improved being used for other purposes, but also has effectively utilized the waste heat of flue gas; Reduced pollution, but existing on the market air preheating apparatus is lower to the utilization rate of flue gas on the one hand to environment; Because the temperature difference of turnover tracheae is bigger, the internal stress that will cause managing is very big, when the equipment time is used longly on the other hand; Pipe is easy to generate crackle, thereby has also influenced the service life of equipment itself, and need regularly check during use; Otherwise can cause very serious security incident, also pretty troublesome during clean and maintenance in addition.
Summary of the invention
The purpose of the utility model is to solve the weak point that above-mentioned prior art exists, and provides a kind of and can make full use of flue gas heat that boiler discharges, increases operation rate, prolongation equipment service life itself, safeguards the air preheating apparatus that gets up to be more prone to.
The utility model is realized through following technical scheme:
A kind of air preheating apparatus that makes full use of the boiler exhaust gas heat comprises cylindrical shell 1, and its special character is that the upper end of cylindrical shell 1 is provided with smoke air inlet 3; The lower end of cylindrical shell 1 is provided with flue gas gas outlet 5, is provided with heat exchanger tube 2 in the cylindrical shell 1, and cylindrical shell 1 one sides are respectively equipped with inlet box 7 and go out gas tank 9; Be connected with air inlet 6 on the inlet box 7; Go out gas tank 9 and be provided with air gas outlet 8, cylindrical shell 1 opposite side is provided with middle housing 4, and cylindrical shell 1 adopts carbon steel or stainless steel material to process with heat exchanger tube 2.
The air preheating apparatus that makes full use of the boiler exhaust gas heat of the utility model; The whole horizontal type structure that adopts; So more help making full use of the heat of flue gas, and regular maintenance is also convenient, has not only improved operating efficiency; Also reduced maintenance cost, improved economic benefit of enterprises to enterprise.
Description of drawings
Fig. 1: the utility model makes full use of the air preheating apparatus structural representation of boiler exhaust gas heat;
Among the figure: 1: cylindrical shell; 2: heat exchanger tube; 3: smoke air inlet; 4: middle housing; 5: the flue gas gas outlet; 6: air inlet; 7: inlet box; 8: the air gas outlet; 9: go out gas tank.
The specific embodiment
Provide the specific embodiment of the utility model below with reference to accompanying drawing, be used for the formation of the utility model is done further explain.
Embodiment 1
A kind of air preheating apparatus that makes full use of the boiler exhaust gas heat of present embodiment comprises cylindrical shell 1, and the upper end of cylindrical shell 1 is provided with smoke air inlet 3; The lower end of cylindrical shell 1 is provided with flue gas gas outlet 5, is provided with heat exchanger tube 2 in the cylindrical shell 1, and cylindrical shell 1 one sides are respectively equipped with inlet box 7 and go out gas tank 9; Be connected with air inlet 6 on the inlet box 7; Go out gas tank 9 and be provided with air gas outlet 8, cylindrical shell 1 opposite side is provided with middle housing 4, and cylindrical shell 1 adopts stainless steel material to process with heat exchanger tube 2.
In actual use; Outside air gets into from air inlet 6, and flue gas gets into from smoke air inlet 3 simultaneously, behind heat exchanger tube 2 heat-shifts; Air after the heating is discharged by air gas outlet 8 via middle housing 4, and residual flue gas is discharged through flue gas gas outlet 5.
The air preheating apparatus that makes full use of the boiler exhaust gas heat of present embodiment; The whole horizontal type structure that adopts; So more help making full use of the heat of flue gas, and regular maintenance is also convenient, has not only improved operating efficiency; Also reduced maintenance cost, improved economic benefit of enterprises to enterprise.
