The specific embodiment three: in conjunction with Fig. 1, present embodiment is described, present embodiment is different from the specific embodiment one or two is that it also increases slag remover 1-14 is arranged, slag remover 1-14 be arranged on fire grate 10 outputs and be positioned at main stove 1 below.The slag that fuel combustion produces is got rid of by slag remover 10.Other composition and annexation are identical with the specific embodiment one or two.
Operation principle of the present invention:
When hot-blast stove of the present invention was connected with a dryer: hot-blast outlet 21 is connected with upper dryer section import on dryer, and upper waste gas air inlet 20 and lower waste gas air inlet 23 were connected with lower dryer section outlet on dryer;
When hot-blast stove of the present invention was connected with two dryers: hot-blast outlet 21 is connected with upper dryer section import on the I dryer, and upper waste gas air inlet 20 and lower waste gas air inlet 23 were connected with lower 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), at first flame and flue gas that fuel combustion produces heat arch heating tube 1-5, flame and flue gas enter in cigarette bridge heat exchanger 2 and with flue gas heat exchange tube 2-4 through smoke pipeline 5 and heat, 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 by flue gas all after heating (be in air heat exchanger 3 natural winds become hot blast) be blown into chimney and enter atmosphere.The first sedimentation in burner hearth expansion chamber 1-4 of a large amount of dust that fuel combustion produces, a small amount 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 air heat exchanger 3 under the suction function of the lower dryer section main air blower of II dryer or I dryer, through just entering lower dryer section or II dryer heating cereal after air heat exchanger 3 heating.The lower dryer section of I dryer or II dryer moisture (waste gas) out, 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 case 1-2 wall in main external box of furnace 1-1 wall and the main stove leaves, and absorbs the heat of case 1-2 wall in 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 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 through inlet box 1-9, and the outlet air end 1-13 by arch heating tube 1-5 after heating enters hot blast mixing chamber 9.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 by hot-blast outlet 9-1 with the cold gas of heating, by the upper 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 dryer to the rear a large amount of steam that produce of cereal heating.
2, the recycling of cooling air: at the cooling section of dryer, the cold gas after the cooling cereal of air-cooler 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, after the heating of repeatedly flowing through commutating in flue gas heat-exchange unit 2, also enters hot blast mixing chamber 9 from cigarette bridge heat exchanger tube 6, together is inhaled into the upper dryer section oven dry cereal of II dryer or I dryer.Even in the winter time usually all higher than zero degree, these heat recovery have reduced the heat that directly heating consumes to outdoor cold air equally, save the energy, have increased the thermal efficiency of hot-blast stove because of cold gas.
