Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
As shown in the figure, body of heater 17 bottoms are provided with combustion chamber 6, cold wind import 4, hot-blast outlet 5, exhaust opening 1, fire door 2 respectively, the heat exchange wall of 6 outsides, combustion chamber and top body of heater 15 is provided with center heat exchange layer 9, interior heat exchange layer 12, outer heat exchange layer 11 and furnace body outer wall 18 from the inside to the outside, constitute hot-flow flue 10, flue 8, cold air duct 7 respectively, what body of heater 17 tops were provided with dark concave structure takes one's place thermosphere 16 and the adjustable air inlet 15 of corresponding connection, takes one's place thermosphere 16 outside top and communicates with hot-flow flue 10.Body of heater 17 bottoms of present embodiment are provided with base 20, the cold wind import 4 that communicates with cold air duct 7 is set between body of heater 17 and the base 20, corresponding flue 8 bottoms are provided with dust chamber 3 and corresponding dust mouth 21, exhaust opening 1 on the base 20, respective combustion chamber 6 bottoms are provided with ash hole 19 on the base 20, make its smoke evacuation, go out dirt, ash discharge is convenient.Cold wind import 4 is connected with cold air duct 7, hot-flow flue 10, hot-blast outlet 5, takes one's place thermosphere 16 and communicates with flue 8 upper ends with the interlayer of center heat exchange layer 9, and the lower end is connected with exhaust opening 1 by dust chamber 3.Center heat exchange layer 9, take one's place on the thermosphere 16 by on air one sidewall flow deflector 13 is set.Flow deflector 13 has been strengthened heat-transfer effect, has increased heat transfer area, reduces the volume of equipment relatively, has saved manufacturing cost, and plays the air conducting effect, reaches energy-saving effect.Be equipped with dust arrester 14 in the flue 8, this dust arrester 14 is the dedusting semicircular ring of two symmetries, on each dedusting semicircular ring pull bar connected vertically is set.Dust arrester 14 can carry out timely ash disposal to it in hot-blast stove operation or any period of stopping transport, and prevents that flue 8 from stopping up, strengthen heat exchanger effectiveness, reduce the flue resistance and the dust exhausting concentration of hot-blast stove, further reached energy-conservation and effect environmental protection, and prolong the service life of hot-blast stove.Cold wind mainly enters hot-blast stove from cold wind import 4, through cold air duct 7, hot-flow flue 10, behind outer heat exchange layer 11, interior heat exchange layer 12, center heat exchange layer 9 absorption heat, leaves hot-blast stove from hot-blast outlet 5.In addition, enter the part cold wind of hot-blast stove, enter hot-flow flue 10 through after taking one's place thermosphere 16 preheatings from adjustable air inlet 15.Take one's place thermosphere 16 by what 6 the positive top in the combustion chamber was provided with, can be in time and absorb the radiant heat of fuel combustion flue gas fully, hot side is long-pending to be reduced relatively because the comparison of radiant heat transfer area is spread, and has dwindled the volume of whole hot-blast stove, has also just saved the hot-blast stove manufacturing cost.And the setting of taking one's place thermosphere 16 also makes grit in the flue gas be clashed into and drops, and reaches the rough dusting effect.By regulating the air quantity of air inlet 15, can regulate the temperature of control hot-air, and improve the efficient of heat exchange.
