The specific embodiment
As shown in Figure 1, the utility model high-efficient energy-saving environment friendly vertical hot furnace comprises body of heater 10, body of heater 10 by furnace body support 20, body of heater shrouding 22 and body of heater before shrouding 34 form, the inboard of body of heater 10 is provided with insulating layer of furnace body 21.Body of heater 10 bottoms are provided with the burner hearth 7 that produces high warm flue gas D27 for fuel combustion, be fixedly installed grate 5 on the furnace base 9 of burner hearth 7 bottoms, and the side are provided with flame-proof thermal insulation material layer 11.
In conjunction with Fig. 2 and Fig. 3, the top of burner hearth 7 is provided with heat-exchanging chamber 31, by fixed head 29, a plurality of staggered fin warm-air pipes 30 are installed in heat-exchanging chamber 31, the hypomere of heat-exchanging chamber 31 is equipped with high-temperature flue gas bend pipe 25, impurities removal outlet 24 and smoke exhaust pipe 18, high-temperature flue gas bend pipe 25 and heat-exchanging chamber 31 communicate, the epimere both sides of heat-exchanging chamber 31 correspondence respectively are equipped with cold air duct 28 and hot-blast outlet 33, thermal output blower fan 23 is installed on hot-blast outlet 33, by hot air furnace hot air output flange 35, output hot blast main 19 is installed on the airduct of thermal output blower fan 23.
Temperature sensor 36 and flue blower fan 37 are installed on smoke exhaust pipe 18, the utility model also comprises control cabinet 15, is provided with the control device that is connected with temperature sensor 36 and the low-temperature warning that is connected with this control device indication 12, high temperature alarm indication 13, variations in temperature digital display meter 7 and power supply indication 14 in control cabinet 15.Control device is fixed on body of heater, controls the electric power system of whole each parts of hot-blast stove, and is connected with control device emergency stop switch 16.
The utility model also comprises outside fuel conveying auger 4 with auger shell 3, the feed end of fuel conveying auger 4 top is provided with fuel reservoir storehouse 1, the below in fuel reservoir storehouse 1 is equipped with baiting valve 2, the feeding end of fuel conveying auger 4 stretches in burner hearth 7, and on this feeding end, frequency control motor 8 is installed also.Fuel is installed on the fire door of burner hearth 7 send oxygen machine 6.
The course of work of the present utility model:
When the good fire of the interior point of burner hearth 7 (automatic or manual), and when the baiting valve 2 in fuel reservoir storehouse 1 is opened and by fuel conveying auger 4, fuel inputted in burner hearth 7 and send at fuel under the effect of oxygen machine 6, fuel is in the interior aerial fully burning of burner hearth 7, and the D that at this moment produces is high, and warm flue gas 27 is transported to the bottom of heat-exchanging chamber 31 through high-temperature flue gas bend pipe 25.At this moment, the bottom that the high warm flue gas 27 of D just heats staggered fin warm-air pipe 30, hot blast passes to the fin on top from the bottom of fin warm-air pipe 30.Meanwhile, C cold wind air 26 enters in heat-exchanging chamber 31 by cold air duct 28 through the aperture of the front shrouding 34 of body of heater of body of heater 10, and at this moment the high warm flue gas 27 of the D of fin warm-air pipe carries out heat exchange with C cold wind air 26.Last oligomerisation just produces to heat-exchanging chamber hot-blast outlet 33 the pure hot blast 32 of E that totally there is no pollution, and this hot blast is transferred to hot blast air main 19 through hot blast conveying fan 23 again.Hot blast air main 19 is connected with the air inlet of foodstuff drying device.
The flue gas that produces in burner hearth 7 and tar are through smoke exhaust pipe 18 and drain into the flue dust dirt pocket under the effect of flue blower fan 37, then drain into atmosphere through dedusting, removal of impurities, water after absorbing.The ash that burner hearth 7 produces in combustion process, impurity reach because the fuel that does not have completing combustion to be taken away by wind will be discharged outside bodies of heater by impurity discharging port 24, prevent from entering heat-exchanging chamber 31, there is no flue gas with the hot blast that guarantees heat-exchanging chamber 31, there is no dust, do not pollute.
Control device is for detection of flue temperature and is used for controlling the temperature of the pure hot blast 32 of output E.That is: 1, when the temperature of the pure hot blast 32 of output E exceeds the temperature that control device arranges, just high temperature alarm indication 13 occurring reports to the police, this timed unit just cuts off the power supply of flue blower fan 37 immediately, also can cut off the power supply that frequency control motor 8 and fuel send the oxygen machine simultaneously, this moment, burner hearth 7 no longer included fuel input and comburant oxygen, burner hearth 7 no longer includes burned flame, thereby reduces the temperature of the pure hot blast 32 of E.During the temperature that 2, arranges lower than control device when the temperature of the pure hot blast 32 of E of output, at this moment, low-temperature warning indicator lamp 12 is reported to the police, control with timed unit and connect the power supply that flue blower fan 37, frequency control motor 8 and fuel send oxygen machine 6, in burner hearth 7, fuel produces flame and produces immediately the high warm flue gas 27 of D, improves the temperature of the pure hot blast 32 of E.
