Background technology
Boiler is widely used in production and life.Existing boiler is medium small boiler especially, and its heat exchange efficiency is lower, causes carrying a large amount of heats in flue gas, and the flue gas of existing boiler is directly discharged in atmosphere often, thereby has caused heat loss, energy waste.Owing to needing to pass into air in boiler furnace, the intensification of air needs consume fuel, if there be a kind of device and to be used for preheating cold air by the heat recovery in flue gas, can significantly save energy resource consumption.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, easy to use, boiler smoke-gas residual-heat recovering device that can effective recycling flue gas heat.
For solving the problems of the technologies described above, boiler smoke-gas residual-heat recovering device of the present invention comprises casing, its design feature is that the inner chamber of described casing is by upper, lower two tanks diaphragm plate is separated into the flue gas chamber on top, the heat exchanging chamber at middle part and the dust-collecting cavity of bottom, in flue gas chamber, be provided with the smoke chamber midfeather that is divided into smoke input chamber and smoke output chamber, the top of casing offers the mouth that enters being communicated with smoke input chamber, the outlet flue being communicated with smoke output chamber, in the two opposite side walls of casing, offer respectively the air inlet and the gas outlet that are communicated with heat exchanging chamber, the bottom of casing offers the dust-exhausting port being communicated with dust-collecting cavity, dust discharge door is installed on dust-exhausting port, the part connection smoke input chamber being interval with in heat exchanging chamber in many heat exchanger tubes and heat exchanger tube is communicated with dust-collecting cavity and smoke output chamber with dust-collecting cavity another part.
Adopt said structure, enter mouth and connect boiler smoke outlet, outlet flue connects chimney, and gas outlet connects the inlet end of boiler, and air inlet connects air blast.In heat exchanging chamber, under the heat exchange effect of the tube wall of heat exchanger tube, the heat that flue gas carries, by the absorption of air in heat exchanging chamber, is passed into the inlet end of boiler again through the air of preheating, realized the recycling of flue gas heat, has saved the energy.In addition, due to the effect of gravity, the flue dust carrying in flue gas drops in dust-collecting cavity, by dust-exhausting port, can in time flue dust be discharged, visible, and this device also has the effect of purifying smoke.
In space between described each heat exchanger tube, interval is provided with the blast fence of polylith cross arrangement, and each blast fence is divided into the space between heat exchanger tube the roundabout runner flowing through for air.The speed that blast fence can slow down Air Flow in heat exchanging chamber is set, makes air through fully flowing out after preheating, improved heat exchange efficiency.
The border of described heat exchanger tube outer wall is installed with radiating fin.Radiating fin is set, has increased the heat exchange area of heat exchanger tube, be more conducive to heat exchange.
The bottom of described casing is back taper, and described dust-exhausting port is opened on cone point.Dust storage chamber is arranged to back taper, and flue dust can glide along the inwall tilting, and is convenient to flue dust collecting and focuses on.
Described bottom half offers for observing the transparent windows of dust-collecting cavity.By the flue dust thickness in transparent windows observable dust storage chamber, when flue dust is saved bit by bit certain thickness, open dust discharge door, flue dust is discharged, avoided flue blockage.
In sum, the present invention has advantages of simple in structure, easy to use and can effective recycling flue gas heat.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
Fig. 1 is the structural representation of one embodiment of the present invention.
The specific embodiment
With reference to accompanying drawing, boiler smoke-gas residual-heat recovering device of the present invention comprises casing 1, the inner chamber of casing 1 is separated into the flue gas chamber 2 on top by upper box dividing plate 11 and lower box dividing plate 12, the heat exchanging chamber 3 at middle part and the dust-collecting cavity 4 of bottom, in flue gas chamber 2, be provided with the smoke chamber midfeather 5 that is divided into smoke input chamber 21 and smoke output chamber 22, the top of casing 1 offer be communicated with smoke input chamber 21 enter mouth 23, the outlet flue 24 being communicated with smoke output chamber 22, in the two opposite side walls of casing 1, offer respectively the air inlet 31 and the gas outlet 32 that are communicated with heat exchanging chamber 3, the bottom of casing 1 offers the dust-exhausting port 41 being communicated with dust-collecting cavity 4, dust discharge door 42 is installed on dust-exhausting port 41.Wherein, the bottom of casing 1 is back taper, and dust-exhausting port 41 is opened on cone point.The part connection smoke input chamber 21 being interval with in heat exchanging chamber 3 in many heat exchanger tubes 6 and heat exchanger tube 6 is communicated with dust-collecting cavity 4 and smoke output chamber 22 with dust-collecting cavity 4, another part.Wherein, enter mouth 23 and connect boiler smoke outlet, outlet flue 24 connects chimney, and gas outlet 32 connects the inlet end of boiler, and air inlet 31 connects air blast.In heat exchanging chamber 3, under the heat exchange effect of the tube wall of heat exchanger tube 6, the heat that flue gas carries, by the absorption of air in heat exchanging chamber 3, is passed into the inlet end of boiler again through the air of preheating, thereby realizes the recycling of flue gas heat.In addition, in the effect of gravity, the flue dust carrying in flue gas drops in dust-collecting cavity 4, by dust-exhausting port 41, can in time flue dust be discharged.Dust storage chamber 4 is arranged to back taper, and flue dust can glide along the inwall tilting, and is convenient to flue dust collecting and focuses on.
