The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.Following explanation is to adopt the mode of giving an example, but the protection domain of the utility model should not be limited to this.
Present embodiment is to be made up of heating furnace 1`, hot-blast furnace body and chimney 20.
Heating furnace 1` is horizontal coal-fired stove, is to be made up of heating furnace body 1, ashcan 2, burner hearth 3 and grate 4, and the rear end of burner hearth 3 communicates with hot-blast furnace body.
Hot-blast furnace body is a cuboid (other shape can be considered the equivalents of a utility model) cavity; Be to constitute by left wallboard 6, right wallboard 23, front wallboard 27, rear wall plate 26, top board 22 and base plate 25 (all adopting refractory material to make); Have gas approach 5 on the wallboard 6 of a left side; Heating furnace 1` device is in left wallboard 6 outsides, and the rear end of burner hearth 3 promptly communicates with gas approach 5.
In hot-blast furnace body, also be provided with by left side dividing plate 8 with right side partition 19 and (can be one or two or three or other quantity more than one; 20 of this example employings) heat-exchange device that heat exchanger tube 11 constitutes; The left side dividing plate 8 of this heat-exchange device and right side partition 19 with the inner chamber of hot-blast furnace body be separated between the buffering of a left side 7 and right buffering between 21, between the buffering of a left side 7 and right buffering between have left maintenance door 10 and right maintenance door 24 in 21.
On top board 22, have hot-blast outlet 13, and at this device blower fan 12 above hot-blast outlet 13; On base plate 25, the cold wind that has (can be one or two or three or other quantity, this example adopts 30) more than one enters hole 15, and the bottom of entering hole 15 at cold wind also is provided with cold wind air inlet duct 14, and this cold wind air inlet duct 14 enters hole 15 with cold wind and communicates.
Constitute between a left side wallboard 6 and the left side dividing plate 8 left side cushion between 7; Constitute between right buffering 21 between right side partition 19 and the right wallboard 23, chimney 20 devices are at the place, the upper right corner of hot-blast furnace body, and 21 are communicated with between the buffering of the right side.
The right side of dividing plate 8 also is provided with left side insulated wall 9 in the left side, also is provided with right side insulated wall 18 in the left side of right side partition 19, constitutes hot blast chamber 16 between left side insulated wall 9 and the right side insulated wall 18; Device has accumulation of heat thing 17 (accumulation of heat thing 17 can adopt the bigger material of specific heat coefficient, and like cobble etc., accumulation of heat thing 17 is deposited in the hot blast chamber 16, is wrapped in heat exchanger tube 11, but the accumulation of heat thing of piling up 17 can be breathed freely) in the middle and lower part of hot blast chamber 16.
Before the use, the outlet of blower fan 12 is communicated with the hot blast import of the facility that needs heat supply, cold wind air inlet duct 14 is communicated with (also directly be communicated with space outerpace, this example needs the return air inlet of the facility of heat supply with connection be that example describes) with the return air inlet of the facility that needs heat supply.
During use; On the one hand, start blower fan 12, need the cold air in the facility of heat supply to be taken out in cold wind air inlet duct 14 by the return air inlet of the facility that needs heat supply; And then enter hole 15 by cold wind and get in the hot blast chambers 16; And flow to the top of hot blast chamber 16 through the gap of accumulation of heat thing 17, and take out hot blast import by hot-blast outlet 13, blower fan 12 at last to the facility that needs heat supply, entering needs in the facility of heat supply.On the other hand, with burner hearth 3 burning that fire coal places heating furnace 1`, the flue gas of generation is through gas approach 5, gets between the buffering of a left side in 7; Because 7 space is more many greatly than gas approach 5 between left side buffering, thereby, getting between the buffering of a left side flue gas in 7, its flowing velocity reduces many, makes that the most of dust in the flue gas lands on 7 bottom surfaces between the buffering of a left side; Through the flue gas of first sedimentation, get into and flow in the heat exchanger tube 11 between right buffering in 21; Through in the process of heat exchanger tube 11, after high-temperature flue gas carries out sufficient heat exchange through the accumulation of heat thing 17 in heat exchanger tube 11 and the hot blast chamber 16 and the cold air of flowing through, get between right buffering in 21; Further reduce flowing velocity at this; Thereby dust in flue gas is further sedimentation during this time, is discharged by chimney 20 at last; At this moment, dust in flue gas content seldom.
Because accumulation of heat thing 17 in the hot blast chamber 16 and the cold air of flowing through all are heated; Thereby; Take out air themperature to the hot blast import of the facility that needs heat supply than higher by blower fan 12,, improve its temperature inside so can heat to the hot facility of need (like warmhouse booth etc.).Hot blast carries out sufficient heat exchange in the hot facility of need after; Need the return air inlet of temperature is lower in the hot facility the air facility through needing heat supply to get into hot blast chambers 16 and add heat utilization once more through cold wind air inlet duct 14; Between hot blast chamber 16 and the hot facility of need, just form hot air circulation like this, improve the heat energy utilization rate.
After having used a period of time, can by left maintenance door 10 and right maintenance door 24 get between the buffering of a left side 7 and right buffering between in 21, clean, safeguard, and clean the dust in each root heat exchanger tube 11.
Because heat exchanger tube 11, left side dividing plate 8 and right side partition 19 all adopt metal material to make, firm welding has been guaranteed the high-seal of hot blast chamber 16, has stopped the possibility that flue gas gets into hot blast chamber 16, has guaranteed the cleaning of hot blast.
In use, as run into weather forecast and show that temperature obviously rises, and can shift to an earlier date 2-3 days heating furnace 1` is ceased fire; At this moment the accumulation of heat thing 17 in the hot blast chamber 16 has stored great amount of heat, after truce, gos up during this period of time to temperature, promptly by the air in the accumulation of heat thing 17 heat hot air compartments 16; When the hot facility of need needs heat supply; Open blower fan 12, the hot-air in the hot blast chamber 16 is sent into needs hot facility, and carries out hot air circulation.
The heat accumulating type coal-fired hot-blast stove of the utility model both had been applicable to the heat supply in the industrialized agriculture, also was applicable to the heating places that needs in the industries such as medicine, chemical industry, food through the heated-air drying material.
