Abstract
The utility model relates to a graphite pipe turbolator type air preheater. The graphite pipe turbolator type air preheater comprises a preheater body, an air inlet, an air outlet, a smoke inlet and a smoke outlet, wherein the preheater body consists of a steel frame and a wall plate, the air inlet and the air outlet are arranged at two sides of the preheater body correspondingly, the smoke inlet and the smoke outlet are arranged at two ends of the preheater body correspondingly, pipe plates are arranged at two ends inside the preheater body, at least two turbolator graphite pipes are arranged between the two pipe plates, air enters from the air inlet and is discharged from the air outlet through the turbolator graphite pipes, and smoke enters from the smoke inlet and is discharged from the smoke outlet through the turbolator graphite pipes; the turbolator graphite pipes are of graphite light pipes in which spoilers are arranged evenly, and two ends of the turbolator graphite pipes are hermetically arranged on the pipe plates by flexible graphite rings. For the graphite pipe turbolator type air preheater, non-metal graphite is as a heat exchange element, the spoilers are additionally arranged in the graphite heat exchange pipes so as to increase flowing turbulence in the pipes, the heat exchange coefficient in the pipes is improved, and the application range is wide.
Description
Technical field
The utility model relates to air preheater, refers in particular to a kind of inside of adopting and is provided with the graphite-pipe turbolator regenerative air heater that the spoiler graphite-pipe is done heat exchange element.
Background technology
In the petroleum chemical industry residual neat recovering system, want on the one hand the reduce exhaust gas temperature at present, improve heating furnace, boiler thermal output, reduce energy consumption.On the other hand, owing to contain sour gas in the flue gas, cross when low when exhaust gas temperature, can cause the low-temperature flue gas dew point corrosion, decrease ring apparatus.
Summary of the invention
The purpose of this utility model is for the defective that exists in the background technology and problem improvement and bring new ideas in addition, provides a kind of withstand corrosion, heat exchange efficiency height, compact conformation, the life-span is long, cost is low, the significant graphite-pipe turbolator of energy-saving effect regenerative air heater.
The technical solution of the utility model is a kind of preheater body that is comprised of steelframe and wallboard that comprises of structure, correspondence is arranged on air intake and the air outlet slit of preheater body both sides, reach correspondence and be arranged on the smoke inlet at preheater body two ends and the air preheater of exhanst gas outlet, wherein:
Preheater internal body two ends are provided with tube sheet, at least two turbolator graphite-pipes are set between two tube sheets, air is entered by air intake and by being discharged by air outlet slit in the turbolator graphite-pipe, flue gas is entered by smoke inlet and discharged by exhanst gas outlet by the turbolator graphite-pipe is outer;
Described turbolator graphite-pipe is the graphite light pipe, is provided with uniformly spoiler in the pipe, and turbolator graphite-pipe two ends are seal-installed on the tube sheet by the soft graphite ring.
Advantage of the present utility model and beneficial effect:
1, the utility model with nonmetal graphite as heat exchange element, graphite anti-corrosion, thereby can solve steel tubular air heater cold end corrosion, Air Leakage.
2, the utility model is set up spoiler in Graphtic heat exchanging pipe, increases flow disturbance in the pipe, improves the intraductal heat exchange coefficient, and its Coefficient K has largely than general tubular air preheater to be increased.
3, the utility model applied range except petrochemical industry, can also be widely used in the industries such as boiler, metallurgy, cement, food medicine as equipment such as corrosion resistant air preheaters.
Description of drawings
Fig. 1 is one of the utility model structural representation.
Fig. 2 is two of the utility model structural representation.
The specific embodiment
By Fig. 1,2 as can be known, the utility model comprises the preheater body that is comprised of steelframe 3 and wallboard 4, correspondence is arranged on air intake 1 and the air outlet slit 2 of preheater body both sides, and corresponding smoke inlet 7 and the exhanst gas outlet 8 that is arranged on preheater body two ends, wherein:
Preheater internal body two ends are provided with tube sheet 5, at least two turbolator graphite-pipes 6 are set between two tube sheets 5, air is entered by air intake 1 and by being discharged by air outlet slit 2 in the turbolator graphite-pipe 6, flue gas is entered by smoke inlet 7 and passes through and discharged by exhanst gas outlet 8 outside the turbolator graphite-pipe 6;
Described turbolator graphite-pipe 6 is the graphite light pipe, is provided with uniformly spoiler in the pipe, and turbolator graphite-pipe 6 two ends are seal-installed on the tube sheet 5 by the soft graphite ring.
