Operation principle of the present invention:
When hot-blast stove of the present invention is connected with a dryer: be connected with the upper dryer section import on dryer by hot-blast outlet 9-1, upper waste gas air inlet 1-6 and lower waste gas air inlet 1-7 export with the lower dryer section on dryer and are connected;
When hot-blast stove of the present invention is connected with two dryers: be connected with the upper dryer section import on No. I dryer by hot-blast outlet 9-1, upper waste gas air inlet 1-6 and lower waste gas air inlet 1-7 export with the lower dryer section on No. II dryer and are connected;
1, the recycling of waste gas: fuel feeds fire grate 10 (handwarmer is by manually feeding) by feeding hopper 8, first the flame that fuel combustion produces and flue gas heat arch heating tube 1-5, flame and flue gas to enter in cigarette bridge heat exchanger 2 through smoke pipeline 5 and are heated by flue gas heat exchange tube 2-4, flue gas after heat exchange is advanced into air heat exchanger 3 before continuing under the effect of external smoke suction machine, and all air heat-exchange pipe 3-2 all heated by flue gas after (natural wind namely in air heat exchanger 3 becomes hot blast) be blown into chimney and enter air.A large amount of dust first sedimentation in burner hearth expansion chamber 1-4 that fuel combustion produces, a small amount of dust is removed by smoke suction machine bottom air heat exchanger 3.The slag that fuel combustion produces gets rid of (handwarmer is removed by fire door 1-8) by slag remover 1-14.
Air, under the suction function of the lower dryer section main air blower of No. II dryer or No. I dryer, is continuously inhaled in air heat exchanger 3, after air heat exchanger 3 heats, just enter lower dryer section or No. II dryer heating grains.The lower dryer section of No. I dryer or No. II dryer moisture out (waste gas), under the effect of blower fan, wherein a part of moisture is blown in lower airway 1-19 by lower waste gas air inlet 1-7, under the effect of median septum 1-3, moisture leaves to case 1-2 wall in main external box of furnace 1-1 wall and main stove, absorb the heat of case 1-2 wall in main stove, internal box wall plate is lowered the temperature, after moisture continues to be forwarded to the front end of main stove 1, enter airway 1-10 from lower waste gas circulation mouth 1-16, then enter hot blast mixing chamber 9; Another part moisture is blown in upper airway 1-18 by upper waste gas air inlet 1-6, enters in arch heating tube 1-5, enter hot blast mixing chamber 9 after heating by the outlet air end 1-13 of arch heating tube 1-5 through inlet box 1-9.Cooling air by cigarette bridge heat exchanger cooling air import 2-7 enter blown into cigarette bridge heat exchanger 2 after heated, hot blast mixing chamber 9 is entered through cigarette bridge heat exchanger tube 6, through hot-blast outlet 9-1 after two parts moisture mixes with the cold gas of heating, sucked the upper dryer section of No. II dryer or No. 1 dryer by No. II dryer or No. 1 dryer hypomere main air blower, hot blast is excluded outside dryer to a large amount of steam produced after heat grain.
2, the recycling of cooling air: at the cooling section of dryer, the cold gas after air-cooler cooling cereal is divided into two parts, and a part is blown at the bottom of hot-blast stove to fuel combustion supporting by cooling air air inlet 1-17; Another part enters flue gas heat-exchange unit 2, and after heating of repeatedly flowing through commutating in flue gas heat-exchange unit 2, also enter hot blast mixing chamber 9 from cigarette bridge heat exchanger tube 6, the upper dryer section being together inhaled into No. II dryer or No. I dryer dries cereal.Even if because cold gas is in the winter time usually all higher than zero degree, these heat recovery, decrease equally and directly heat to outdoor cold air the heat consumed, and save the energy, add the thermal efficiency of hot-blast stove.
