The specific embodiment
As shown in Fig. 1,2, lay heating furnace in the middle of the Heat Room inner bottom part of hot blast stove for flue-cured tobacco of the present utility model, be provided with the vertical pipe type heat exchanger of three double as chimneys in the heat transfer space of heating furnace body 1 top, Heat Room is gone along with sb. to guard him by brick wall 23 all around and concrete roof 16 and is formed, heating furnace is fixing by brick base 5 supporting, has formed air channel 4 at the bottom of the circulated air simultaneously between each bearing.Heating furnace is made up of body of heater 1, fire grate 2, cinder chamber 3, shoot door 6, fire door 7, burner hearth 8, furnace roof steel plate 9 and critical pieces such as the butt joint collar 25, furnace bottom blast pipe 24.Body of heater 1 is the steel plate weldment, and fire grate 2 is combined by some cast iron stove strips; As shown in Fig. 3,4, furnace roof steel plate 9 is the thick steel plate of 5mm, diameter, quantity according to difunctional vertical pipe type heat exchanger 17 pipelines that will dock have been cut corresponding hole with the position on this steel plate, burn-on around in each hole again steel pipe pipe nipple of two different-diameters, just formed the stove roof plate butt joint collar 25, can be installed in heat exchanger 17 pipelines in the collar easily; The size of furnace bottom blast pipe 24 should match with supporting blower outlet size, and air outlet should be installed non-return valve.
Heat-exchange system in the Heat Room is mainly the vertical pipe type heat exchanger 17 of double as chimney, according to the heating demand demand, this heat exchanger 17 is by three, the steel pipe of four or some is formed, the heat exchanger tube bottom is by the 25 butt joint location of the butt joint collar on the furnace roof steel plate, the top is by refractory concrete top board 16 location, a shape frame is installed at the standpipe upper port place of heat exchanger 17, pulley 15 is installed in the stull of shape frame 14, the top of door shape frame is equipped with umbrella 13, on the body of rod that flow-disturbing string 18 is suspended by heat exchanger 17 standpipe internal riser central axis positions and the body of rod thereof from top to bottom the fixing spoiler of string dress constitute, around each spoiler and leave flue gas between the standpipe inner tubal wall and pass through the gap, the top of flow-disturbing string 18 is provided with a location cross bar 11, location cross bar 11 can move up and down along the flow-disturbing string moving guide rail 10 that the perpendicular support in the both sides of door shape frame forms, the upper end of stay cord 12 is walked around on the location cross bar 11 that pulley 15 tightly ties up to flow-disturbing string 18 tops, when the needs deashing, can spur stay cord lower end 22 by the operator, flow-disturbing string 18 is moved up and down carry out deashing, pulley also is housed in concrete roof 16 1 edges that are provided with stay cord.
Brickwork separating wall top in hot-blast stove and cigarette-filling house, be provided with circulated air air outlet 20, and ventilating fan 21 is installed at this, this partition wall bottom is provided with circulated air return air inlet 19, during ventilating fan 21 runnings, hot-air is sent into cigarette-filling house from air outlet, and the wet air that again the cigarette-filling house bottom turned cold is withdrawn into hot-blast stove, enters cigarette-filling house's baking tobacco leaves again thereby make air constantly be recycled heating.
Operation principle: the difunctional vertical pipe type heat exchanger 17 that the utility model has adopted chimney to combine with heat exchanger, sufficient heat exchange area is not only arranged, and higher heat transfer coefficient is arranged, so they are good heat exchanger, have the function of chimney again concurrently, flue gas is discharged under higher draft and very little resistance smoothly, therefore have higher draft than transverse tube type heat exchanger, the flow of flue gas resistance is less simultaneously; In the vertical pipe type heat exchanger 17 of double as chimney, dispose flow-disturbing string 18, the high-temperature flue gas of flowing through there is very strong perturbation action, strengthened flow perturbation greatly, can obviously improve flue gas flow rate and heat transfer coefficient, so the heat exchange efficiency height has significantly been strengthened heat exchange, simultaneously, flow-disturbing string 18 is again fabulous dust remover, can be in operation to spur up and down at any time to remove the dust stratification in the pipe; Under at the bottom of the heating-furnace, be provided with air channel, the end 4, heating furnace and heat exchanger and reasonable, the layout compactness in the gap between the wall simultaneously on every side, improved air velocity, make the equipment surface in the hot-blast stove all become heat-transfer surface, so this hot-blast stove is with low cost, it is simple to make, heat exchange efficiency is high, deashing is convenient; Air channel, the end 4 force behind the humid air transversal flow furnace bottom that flows back to from the flue-cured tobacco chamber again along around the parallel baffled furnace wall rise, not only make full use of furnace bottom and the furnace wall area carries out heat exchange, and ascending air be evenly distributed, strengthened heat exchange; The lime-ash that draws off from fire grate 2 is temporarily stored in the cinder chamber, but warm-up combustion-supporting air, and whole steel plate body of heater of while also can be used as radiator and adds hot-air; Ventilating fan 21 can be sent hot-air to the flue-cured tobacco chamber from air outlet 20 and remove to dry tobacco leaf, makes the humid air that returns from return air inlet 19 be heated output by heating furnace and heat exchanger once more again simultaneously, so moves in circles, and finishes the production and the conveying function of hot blast.
When the utility model uses, earlier by adding fuel on the fire grate 2 of fire door 7 in burner hearth 8, after the fuel combustion fully, produce a large amount of high-temperature flue gas, high-temperature flue gas removes to add hot-air by body of heater 1 as radiator on the one hand, upwards flow on the one hand in the heat exchanger 17 of many steel standpipes compositions, with the outer air of higher heat transfer coefficient heating tube, send hot-air to the flue-cured tobacco chamber from air outlet 20 by ventilating fan 21 and remove to dry tobacco leaf, the humid air that produces during baking tobacco leaves returns hot-blast stove from return air inlet 19 after descending, be heated output by heating furnace and heat exchanger once more, so move in circles, finish the production and the conveying of hot blast.
For enhanced heat exchange, enhancing heat transfer can in time be removed the dust stratification in the heat exchanger 17 at this hot-blast stove flow-disturbing string 18 that spurs up and down at any time in service.
