Abstract
The utility model relates to a hot-air generator, in particular relates to a direct-heating-typed hot-blast stove, and comprises a stove body (1) and a hearth inner container (8) that is arranged inside the stove body (1), and a combustor that is arranged on the stove body (1) to be matched with the hearth inner container (8), and is characterized in that a gap is arranged between the inner surface of the stove body (1) and the outer surface of the hearth inner container (8), so as to form a ring-shaped air passage; a hot smoke outlet (5) is arranged on one end, which is close to the outlet of the hearth inner container (8), of the stove body (1); one end, which is away from the outlet of the hearth inner container (8), of the stove body (1) is provided with a cool-smoke inlet (3). With the technical proposal hereinabove, for the application areas that requires the hot-coal to heat but has low requirement on the cleanliness of the hot air, for example, removing the white smoke of the chimney in a ceramics factory, the indirect heating is changed to be the direct heating, so that the high-temperature smoke is directly mixed with the heated air, thereby not only saving the heat-exchanging equipment, but also greatly improving the heating efficiency.
Description
Technical field
The utility model relates to a kind of hot air generator, in particular for the direct-heating type hot-blast stove of ceramics factory.
Background technology
At present in the hot-blast stove that ceramics factory uses, the overwhelming majority all is the indirect heating type hot-blast stove, mainly form by combustion chamber and cigarette-air heat exchanger, the i.e. high-temperature flue gas that produces by the combustion chamber, come the indirect air by heat exchanger, the high-temperature hot-air of the cleaning that obtains is made heating agent, apply to technical process.
The advantage of indirect heating type hot-blast stove is the high-temperature hot-air that can obtain cleaning; Shortcoming is that the thermal efficiency is relatively low, and has increased huge heat-exchanger rig, the structure relative complex.
The utility model content
The purpose of this utility model provides a kind of heat-exchange apparatus, higher direct-heating type hot-blast stove of the thermal efficiency save.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of direct-heating type hot-blast stove, comprise body of heater and be installed in the interior burner hearth inner bag of body of heater, and be installed in the burner that cooperates with this burner hearth inner bag on the body of heater, its special feature is: form annular air channel thereby be provided with the gap between described body of heater inner surface and burner hearth inner bag outer surface, on the body of heater of described burner hearth inner bag exit one end, be provided with hot exhanst gas outlet, and the end away from this burner hearth inner bag exit is provided with the cold flue gas inlet on body of heater.
Wherein damper is installed in the cold flue gas porch.
Wherein on body of heater, have the combustion-supporting pore that is communicated with the burner hearth inner bag.
Wherein the inner surface at the burner hearth inner bag is equipped with heat-insulating material.
The stokehold gusset plate wherein is installed on body of heater.
Wherein burner is an oil burner.
Further, wherein between body of heater inner surface and burner hearth inner bag outer surface, annular oriffice is installed.
Owing to take technique scheme, for not only needing the heating agent heating but also requirement is not very high application to the hot blast cleanliness factor, as eliminate the white cigarette of ceramics factory's chimney, change indirect into direct heating, high-temperature flue gas is directly mixed with heated air, not only can save heat-exchange apparatus, and improve the thermal efficiency greatly.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Come the utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of direct-heating type hot-blast stove, comprise body of heater 1 and the burner hearth inner bag 8 that is installed in the body of heater 1, and be installed in the burner 2 that cooperates with this burner hearth inner bag 8 on the body of heater 1, thereby between body of heater 1 inner surface and burner hearth inner bag 8 outer surfaces, be provided with the gap and form annular air channel, on the body of heater 1 of burner hearth inner bag 8 exits one end, be provided with hot exhanst gas outlet 5, and the end away from these burner hearth inner bag 8 exits is provided with cold flue gas inlet 3 on body of heater 1.
At cold flue gas 3 places that enter the mouth damper 4 is installed, on body of heater 1, have the combustion-supporting pore 6 that is communicated with burner hearth inner bag 8, inner surface at burner hearth inner bag 8 is equipped with heat-insulating material 10, stokehold gusset plate 7 is installed on body of heater 1, between body of heater 1 inner surface and burner hearth inner bag 8 outer surfaces, annular oriffice 9 is installed.
Burner 2 adopts oil burner 2.Fuel oil is 11 atomizing spray combustions in the combustion chamber, fully mix with the combustion fan air-supply of burner 2, and the high-temperature flue gas of generation and the part of circular passage 13 are heated that cold wet flue gas fully mixes at mixing chamber 12, discharge atmosphere after the drying.The cold wet flue gas of part draws smoke pipe by the ground chimney and introduces circular passage 13, surrounds burner hearth inner bag 8, through flowing after by forward direction after annular oriffice 9 current-sharings, by heat absorption the body of heater 1 radiation loss overwhelming majority is reclaimed, and flows into mixing chamber 12 at last and mixes with combustion product gases.
About body of heater 1 structure: body of heater 1 temperature is higher, circular passage 13 interlayer humidity are bigger, consider that stainless steel has stronger non-oxidizability and good creep strength in hot environment, therefore body of heater 1 inner casing selects for use corrosion resistant plate to make, the shell galvanized sheet, flue is inboard with high temperature thermal insulation material 10 cast-in-sites.In order to keep burner hearth part robustness stokehold gusset plate 7 to adopt QT45-5 cast iron, annular oriffice 9 adopts heat resisting steel to make.Fixed frame welds, paints and form with No. 8 channel-section steels.
The utility model can be used for eliminating the white cigarette of ceramics factory's chimney, eliminates chimney and emits " white cigarette " to take " temperature-raising method ", and flue gas is warming up to 70～90 ℃ of adjustable extents, does not then have white cigarette and produces.The fuel of burner 2 is selected 0# diesel oil for use, and the burn-off rate height can not form secondary pollution basically.
