Abstract
The utility model relates to a direct-mixing hot blast stove, which is composed of a closed casing, a combustion chamber arranged in the casing, a mixing chamber on the front end of the combustion chamber, an air inlet, a hot blast outlet, etc. The utility model is characterized in that fume with high temperature is mixed with air directly to produce hot blast. The utility model solves the problems of high steel consumption, big volume, and the burn of the metal heating surface generated by high temperature oxidation in indirect heat exchanging hot blast stoves. The utility model can be used for drying materials, baking, mine ventilation, etc. The utility model is suitable for high temperature production processes which are used for heating with high temperature and need large quantity of moisture discharging.
Description
The utility model belongs to industrial ventilation equipment, is specially a kind of hotblast stove that is used to produce hot blast.Existing hotblast stove adopts the indirect heating mode more, promptly with thermal-flame or flue gas by metal heated indirect heating air, to produce hot blast, be used for dry materials, mine ventilation etc.Its subject matter is the heated metal local overheating, and the easy oxidation of overtemperature place metal distortion even burn out causes air to leak to fume side, makes hotblast stove reductions of exerting oneself, the heat loss due to exhaust gas increase; Secondly, because the gas one gas heat-transfer surface coefficient of heat transfer is little, metal heated big, and steel consumption is many, and is bulky, and manufacturing cost is higher.For addressing this problem, can adopt heat-resisting alloy steel as easy overtemperature place heating surface, hotblast stove is prolonged work-ing life.But the limit heat resisting temperature of general heat-resisting alloy steel is about 600 ℃, when tube wall temperature surpasses under this temperature long-time running, also heat-resisting alloy steel can be burnt out, and heat-resisting alloy steel costs an arm and a leg, for plain carbon stool about 10 times are multiplied the hotblast stove cost.
The purpose of this utility model is intended to fundamentally solve the problem that has metal heated local overheating of hotblast stove now and oxidation takes place even burn out, and can reduce manufacturing cost, reduces volume.
The technical solution of the utility model is: adopt the directly mixing type hotblast stove, this hotblast stove contains heat exchanger, described heat exchanger contains parts such as the housing of sealing, the mixing section that is installed in the intravital combustion chamber of shell, chamber front end, gas inlet, hot-blast outlet, gas inlet is arranged on the housing and outer and air communication, in communicate with mixing section, the combustion chamber also communicates with mixing section, and mixing section communicates with hot-blast outlet.In described housing, be provided with equal wind annular plate and annular air channel between gas inlet and the mixing section, annular air channel just in time be arranged in the combustion chamber around.It is temperature required that the high-temperature flue gas that the combustion chamber produces and the freezing air that enters from gas inlet directly are mixed at mixing section, sent by hot-blast outlet.
Owing to adopted the mixing section structure, directly mix to come the heats cold air with high-temperature flue gas with freezing air, saved metal heated, therefore the problem that does not exist metal heated oxidation to burn out; Simultaneously can save great deal of steel, both reduce cost, reduce volume again; The annular air channel preheating that is provided with air, reduced thermosteresis.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is the utility model sectional view.
As shown in the figure, enclosed housing 7 outer bread the soft lagging material 8 of one deck, combustion chamber 1 is arranged in the housing 7 and with mixing section 9 and communicates.Around the combustion chamber is annular air channel 2, is provided with equal wind annular plate 6 on the passage 2.Gas inlet 5 is opened on the housing 7 and by annular air channel 2 and communicates with mixing section 9.Mixing section 9 communicates with hot-blast outlet 10 again.Freezing air enters in the housing 7 from gas inlet 5, through passing through annular air channel 2 preheatings behind the equal wind annular plate 6 equably, arrives mixing section 9 and mixes after hot-blast outlet 10 is sent with the high-temperature flue gas that combustion chamber 1 produces, and can be used for dry materials, mine ventilation etc.Hot blast temperature can be controlled by the size that adjusting is installed in the aperture of the air door 4 on the gas inlet 5 or regulates the burner load, to satisfy the requirement of user to hot blast temperature.
Claims (2)
1, a kind of directly mixing type hotblast stove, contain heat exchanger, it is characterized in that described heat exchanger contains the housing of sealing, is installed in the part such as mixing section, gas inlet, hot-blast outlet of the intravital combustion chamber of shell, chamber front end, gas inlet is arranged on the housing and outer and air communication, in communicate with mixing section, the combustion chamber also communicates with mixing section, and mixing section communicates with hot-blast outlet.
2, directly mixing type hotblast stove according to claim 1 is characterized in that being provided with equal wind annular plate and annular air channel between the gas inlet and mixing section in described housing, annular air channel just in time be arranged in the combustion chamber around.
