Description
Technical field
The utility model relates to the device field that utilizes waste heat in general stove, kiln, oven or the retort, is specially a kind of thermal stress compensation formula radiation preheater.
Background technology
Industrial furnace with combustion gas acquisition heat can give off the great amount of high-temperature flue gas during work, as directly entering atmosphere, not only wastes heat resource, and environment is also had pollution.Many at present employings are with high-temperature flue gas and treat that preheating gas imports in the heat exchanger jointly, make high-temperature flue gas and treat that heat exchange takes place preheating gas in heat exchanger, thereby reach the purpose of utilizing fume afterheat.The tubular radiation recuperator is to can be used for a kind of heat-exchange device that flue gas heat reclaims; Its structure is as shown in Figure 1; Form by collector 1, collector sleeve 11, fin 12, air inlet pipe 21 and escape pipe 22; Collector sleeve 11 is enclosed within outside the collector 1, and the lateral surface of collector 1 is provided with fin 12, and air inlet pipe 21 all connects with collector sleeve 11 with escape pipe 22 and is connected.During use, mobile in collector 1 from the high-temperature flue gas that industrial furnace is discharged, treat that preheating gas flows along the annular gap between collector 1 and the collector sleeve 11 from air inlet pipe 21 input backs, is exported from escape pipe 22 after the high-temperature flue gas heating again.This structure, flowing to of flue gas is single, so being limited in scope of preheating gas, and applicable situation also is restricted.
The utility model content
In order to overcome the defective of prior art, a kind of residual heat using device of simple in structure, applied widely, long service life is provided, the utility model discloses a kind of thermal stress compensation formula radiation preheater.
The utility model reaches goal of the invention through following technical scheme:
A kind of thermal stress compensation formula radiation preheater comprises collector, collector sleeve and fin, and the collector jacket casing is outside collector; The lateral surface of collector is provided with fin, it is characterized in that: also comprise air inlet pipe, escape pipe, arm, arm sleeve and bellows, arm connects with collector and is connected; Be positioned at bellows of front end series connection of arm and collector perforation place on the arm; The arm jacket casing is outside arm, and the lateral surface of arm is provided with fin, and the arm sleeve connects with the collector sleeve and is connected; The air inlet pipe collector connects and connects, and escape pipe connects with the arm sleeve and is connected.
Described thermal stress compensation formula radiation preheater; It is characterized in that: the collector external diameter is 50%～90% of a collector sleeve diameter; The height of fin is 20%～80% of the annular gap width that forms of collector lateral surface and collector sleeve medial surface, and an external diameter of pipe is 50%～90% of an arm sleeve diameter.
When the utility model uses; The high-temperature flue gas of discharging from industrial furnace flows through arm importing collector; Treat that preheating gas flows along the annular gap between collector and the collector sleeve from air inlet pipe input back; Be imported into the annular gap between arm and the arm sleeve again, treat that preheating gas is heated by high-temperature flue gas, exports from escape pipe at last in flow process.
The utility model has increased the flow of flue gas approach through adding arm, has expanded the scope of application of preheater, and the part as chimney can vertically be installed, and also can be installed on the flue gas arm or flue gas house steward of burner outlet.The utility model is again through adding bellows to prevent that thereby when collector high temperature expands, to arm generation axial force arm being moved vertically touches the collector sleeve, effectively compensated the thermal stress defective, has improved the service life of preheater in the industrial furnace.The beneficial effect of the utility model is: simple in structure, the heat recovery rate is high, long service life.
