The technical scheme that its technical problem that solves the utility model adopts is: a kind of hot-blast stove, has body of heater, be provided with furnace wall in the body of heater, have combustion chamber and heat-exchanging chamber in the furnace wall, the front end of combustion chamber is provided with coaling machine, coaling machine top is provided with coal feeding bucket, the two side air compartment connection of combustion chamber is provided with combustion fan, combustion chamber and heat-exchanging chamber communicate in body of heater, has heat exchanger in the heat-exchanging chamber, heat exchanger two sides connection up and down is provided with the cigarette air channel, one end in cigarette air channel is communicated with effluxing, the sidewall of heat-exchanging chamber is provided with hot air outlet that is communicated with the heat exchanger first road heat exchanger tube and the inlet of cold air that is communicated with heat exchanger tail road heat exchanger tube, and the inlet of cold air place is furnished with main air blower.
In order to prevent that heat scatters and disappears, and is provided with heat-insulation layer between inboard wall of furnace body and furnace wall outer wall.
For the flue gas in the combustion chamber is fully burned, be staggeredly equipped with firebreak in combustion chamber upper inside wall and bottom one, promptly firebreak plays the effect of second-time burning.
In order to discharge flue gas easily, be provided with air-introduced machine at the end that effluxes that is communicated with the cigarette air channel.
The beneficial effects of the utility model are: the utility model Combustion of Hot Air Furnace chamber communicates in body of heater with heat-exchanging chamber, be indirect between high-temperature flue gas and air in the body of heater, flue gas and air are respectively walked its road, hot-air cleanliness without any pollution after the heating, heat exchange is fast, the thermal efficiency is up to 65-80%, compact conformation, processing ease, volume is little, and is safe and reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. body of heater, 2. furnace wall, 21. heat-insulation layers, 3. combustion chamber, 31. firebreaks, 4. heat-exchanging chamber, 5. coaling machine, 51. coal feeding buckets, 6. heat exchanger, 7. cigarette air channel, 71. air-introduced machines, 8. hot air outlet, 9. inlet of cold air.
The specific embodiment
As Fig. 1, shown in 2, a kind of hot-blast stove, has body of heater 1, be provided with furnace wall 2 in the body of heater 1, have combustion chamber 3 and heat-exchanging chamber 4 in the furnace wall 2, the front end of combustion chamber 3 is provided with coaling machine 5, coaling machine 5 tops are provided with coal feeding bucket 51, the two side air compartment connection of combustion chamber 3 is provided with combustion fan, combustion chamber 3 and heat-exchanging chamber 4 communicate in body of heater 1, has heat exchanger 6 in the heat-exchanging chamber 4, heat exchanger about in the of 6 two sides be communicated with and be provided with cigarette air channel 7, an end in cigarette air channel 7 is communicated with effluxing, the sidewall of heat-exchanging chamber 4 is provided with hot air outlet 8 that is communicated with heat exchanger 6 first road heat exchanger tubes and the inlet of cold air 9 that is communicated with heat exchanger 6 tail road heat exchanger tubes, inlet of cold air 9 places are furnished with main air blower, combustion fan, main air blower does not draw in the drawings.
As shown in Figure 1, 2, be provided with heat-insulation layer 21 between body of heater 1 inwall and furnace wall 2 outer walls, in case heat scatters and disappears; Combustion chamber 3 upper inside wall and bottom one are staggeredly equipped with firebreak 31, and flue gas is carried out second-time burning, make burning more abundant; The end that effluxes that is communicated with cigarette air channel 7 is provided with air-introduced machine 71, is convenient to the flue gas after the heat exchange is discharged.
The operation principle of hot-blast stove is: coaling machine 5 is sent into combustion chamber 3 from coal feeding bucket 51 and is burnt, main air blower sucks air from cold air air inlet 9 and blows to heat exchanger 6, because combustion chamber 3 communicates in body of heater with heat-exchanging chamber 4, the cold air of the heat of combustion chamber 3 and heat exchanger 6 exchanges, flue gas 7 is discharged from the cigarette air channel by air-introduced machine 71, and the hot-air after the exchange blows out from hot air outlet 8 and delivers to each and use hot equipment.
