Operation principle of the present utility model:
When hot-blast stove of the present utility model linked to each other with a dryer: hot-blast outlet 21 is linked to each other with last dryer section import on the dryer, and last waste gas air inlet 20 and following waste gas air inlet 23 linked to each other with following dryer section outlet on the dryer;
When hot-blast stove of the present utility model linked to each other with two dryers: hot-blast outlet 21 is linked to each other with last dryer section import on the I dryer, and last waste gas air inlet 20 and following waste gas air inlet 23 linked to each other with following dryer section outlet on the II dryer;
1, the recycling of waste gas: fuel is by feeding hopper 8 feeding fire grates 10 (handwarmer is by artificial feeding), flame and flue gas that fuel combustion produces at first heat arch heating tube 1-5, flame and flue gas enter in the cigarette bridge heat exchanger 2 and with flue gas heat exchange tube 2-4 through smoke pipeline 5 and heat, flue gas after the heat exchange is advanced into air heat exchanger 3 before continuing under the effect of external smoke suction machine, and all air heat exchanger tube 3-2 are all heated back (be in the air heat exchanger 3 natural winds become hot blast) by flue gas and are blown into chimney and enter atmosphere.A large amount of dust sedimentation in burner hearth expansion chamber 1-4 earlier that fuel combustion produces, a spot of dust is removed by smoke suction machine in air heat exchanger 3 bottoms.The slag that fuel combustion produces is got rid of (handwarmer is removed by fire door 1-7) by slag remover 10.
Air continuously is inhaled in the air heat exchanger 3 under the suction function of the following dryer section main air blower of II dryer or I dryer, through just entering down dryer section or II dryer heating cereal after air heat exchanger 3 heating.The moisture (waste gas) that the following dryer section of I dryer or II dryer come out, under the effect of blower fan, wherein a part of moisture is blown into down among the airway 1-19 by following waste gas air inlet 1-7, under the effect of median septum 1-3, moisture case 1-2 wall in main external box of furnace 1-1 wall and main stove leaves, and absorbs the heat of case 1-2 wall in the main stove, make the cooling of internal box wall plate, after moisture continues to be forwarded to the front end of main stove 1, enter airway 1-10, enter hot blast mixing chamber 9 again from following waste gas circulation mouth 1-16; Another part moisture is blown among the airway 1-18 by last waste gas air inlet 1-6, enters among the arch heating tube 1-5 through inlet box 1-9, and the heating back enters hot blast mixing chamber 9 by the outlet air end 1-13 of arch heating tube 1-5.Cooling air is entered by cigarette bridge heat exchanger cooling air import 2-7 and is heated after being blown into cigarette bridge heat exchanger 2, enter hot blast mixing chamber 9 through cigarette bridge heat exchanger tube 6, two parts moisture mixes with the cold gas of heating after hot-blast outlet 9-1, by the last dryer section of II dryer or No. 1 dryer hypomere main air blower suction II dryer or No. 1 dryer, hot blast is excluded outside the dryer to a large amount of steam that cereal heating back produces.
2, the recycling of cooling air: at the cooling section of dryer, the cold gas after the air-cooler cooling cereal is divided into two parts, and a part is given fuel combustion supporting at the bottom of being blown into hot-blast stove by cooling air air inlet 1-17; Another part enters flue gas heat exchange device 2, after the heating of repeatedly flowing through commutating in flue gas heat exchange device 2, also enters hot blast mixing chamber 9 from cigarette bridge heat exchanger tube 6, together is inhaled into the last dryer section oven dry cereal of II dryer or I dryer.Because of even cold gas all is higher than zero degree in the winter time usually, these heat recovery have reduced the heat that directly heating is consumed to outdoor cold air equally, save the energy, have increased the thermal efficiency of hot-blast stove.
