Accompanying drawing explanation
Fig. 1: be this use new structure principle schematic;
Fig. 2: the top view that is Fig. 1.
The specific embodiment
Referring to accompanying drawing, provide the utility model specific embodiment, the utility model is described further.
Embodiment 1
A kind of multiplex square anti-burning energy-saving pollutionless coal-fired, comprise upper combustion chamber 5, lower combustion chamber 3 and water jacket 9, dust-storage chamber 1, lower fire grating 2 and water-cooled grate 4, be arranged on the coal feed point 7 of burner hearth side, be arranged on outer courage 13 around of burner hearth and the mixing being connected with burner hearth and block fire tube group 11 and flue 14, whirlpool wind dirt pocket 15, dust absorption fan 19 and chimney 20, in stove, be provided with inner bag 12 and with the water-cooled grate 4 and the water jacket 9 that cross the inner bag that is connected, by water-cooled grate 4, inner bag 12 bottoms are separated into upper combustion chamber 3, the double combustion chamber of lower combustion chamber 5, in lower combustion chamber, anti-fire tube group 6 is set.The anti-fire tube group 6 that top communicates with combustion chamber, the effect of upper combustion chamber 5 is that aflame roaring flame undershoot is to water-cooled grate 4, Double layer burning after the sufficient air of fuel mix on lower combustion chamber 3 and lower fire grating 2, form the vibration repeatedly of burning up and down, until tiny powder is burnt down, flue dust can be discharged to air.High temperature roaring flame arrives and blocks fire tube group 11 heat releases through anti-fire tube group 6 from lower combustion chamber 3, heat is fully discharged, then enter whirlpool wind dirt pocket 15 through flue 14, by dust absorption fan 19, through chimney 20, cigarette ash is discharged.The water inlet pipe and water outlet pipe 17 being connected with outer courage 13 is connected with heating system, intrasystem water circulation operation, and outer courage top is provided with steam vent 18, the gas leak that boiler is produced, thus whole heating system is normally moved.
The utility model principle:
By combustibles, light upper combustion chamber's 5 bunker coals after igniting as thin timber etc., coal expands flame in natural oxygenation, inner bag temperature improves constantly, and flame rushes at the thinner water-cooled grate of arrangement 4 downwards, and in heat medium, part dust and live charcoal falls into lower fire grating 3 and burn away.The flame that Dual-layer is red-hot makes fuel combustion thoroughly and fully, and when significantly heating up, the cinder after burning is settled down to dust-storage chamber's 1 bottom, in dust-storage chamber, is trapped, and regularly removes.High-temperature flue gas is through anti-fire tube group 6, further after absorption heat, enter to arrive and block fire tube group 11 by Decay heat removal, the part powdery flue dust carried secretly in flue gas is when blocking fire tube group 11 on drop value water jacket 9, by dedusting mouth 10, removed, flue gas enters whirlpool wind dirt pocket 15 through flue 14 again, by whirlpool wind dedusting mouth 16, remove remaining flue dust, then cigarette is discharged through chimney 20 by dust absorption fan 19, complete combustion process.
The utility model flue dust is few, thermal effect plateau because of: aflame coal grain undershoot is to lower combustion chamber 3, in lower combustion chamber 3, form and mix hugging with lower fire grating 2, burning thoroughly, until burn down, flue dust can be discharged to air, and the main heat that burning produces is by inner bag 12, anti-fire tube group 6 and block fire tube group 11, reflecting plate 8 is absorbed by water.
The overall process of burning is close in heat-insulating and sealing and carries out, and it is inevitable outcome that environmental protection and energy saving are better than traditional coal furnace, and Inner Wall of Combustion Chamber adopts bellows, blocks fire tube and mines massively and can strengthen heat transfer area with efficient screwed pipe, delays the flame rate of climb, raising heat conduction efficiency.
The utlity model has following advantage:
1, integral type design, simple in structure.The utility model hot-water boiler changes the burner of plain cylindrical furnace into counter-burning type burner, and capacity is larger, for larger heating area, uses, and the life-span is long, sturdy and durable.
2, energy consumption is low.The utility model boiler adopts Double grate back burning back-fire type combustion system, make fuel combustion fully thorough, heat energy is close under sealing state of thermal isolation fully to be discharged, its energy loss-rate plain cylindrical furnace is low, and the setting of economizer and multitube parallel heat dump can carry out towards periphery second heat transmission in the situation that replacing traditional waste gas exhausting device smoke evacuation, its thermal efficiency is higher than plain cylindrical furnace, fractional energy savings >=27%, and during joint, rate reaches more than 12%.
3, thermal effect is high.The utility model burns from top to bottom at the flame of when burning water-cooled grate, and the flame of lower fire grating burns from bottom to top, and two strands of flame fully burns to converge to enter together after inner bag is heated up in lower combustion chamber and blocks the strong heat release of fire tube group, washes away and blocks fire tube group.This kind of combustion system is stereo burning, sufficient combustion, and thermal effect is high.
4, meet environmental requirement.Under this practical boiler combustion status, be close under sealing state of thermal isolation and fully burn, the coal-fired flue dust producing leaves a part at deduster; At ash storage box, leave major part; In whirlpool, wind deduster is all held back, and only needs periodic cleaning, makes in waste gas that normal combustion discharges the contamination particles such as smoke dust, pollutes few.
