Description
Technical field
the boiler flue heat energy exchange device of what the utility model related to a kind of gas-gas formula with firewood is thermal source.
Background technology
firewood boiler is the main Types that existing Zhu Mu processing enterprise uses, and its fuel is bamboo wood industrial wood waste normally, and its use cost lower than coal-burning boiler, and does not have SO
2
deng the gas discharging that harm is larger.But in existing firewood boiler smoke, wood ash content is higher, and the energy recovery in its flue gas is also rare, both pollutes atmospheric environment, does not carry out again the comprehensive utilization of heat energy." the smoke heat energy retracting device " of CN203533592U and " the boiler smoke heat reclamation device " of CN203928802U, is all produce convection current with water and carry out heat exchange by flue in water, belongs to a kind of water-gas heat exchange.For gas-gas heat exchange that flue carries out in atmosphere, because in flue gas, dust burdening is higher, easily make flue inner surface knot grey and plugging, siphunculus ash disposal is inconvenient, and affect the exchange of heat energy, rarely seen have such device.
Utility model content
the technical problems to be solved in the utility model is to provide and a kind ofly adopts the firewood boiler flue heat energy exchange device carrying out heat exchange between gas and gas.
above-mentioned technical problem solves by following technical solution: this gas-gas formula firewood boiler flue heat-exchange device, comprise flue and blower fan, heat smoke inlet tube and warm smoke outlet tube are placed in the top of main body, main body is followed successively by smoke chamber from top to bottom, heat radiation group's body and lower gas ash room, upper smoke chamber and heat radiation group body are for being flexibly connected, there is a rotating shaft between the two, rotating shaft offside has fastening screw, upper smoke chamber and the centre of dispelling the heat in group's body are all in conplane midfeather, heat radiation group body above with have location-plate and lower location-plate on the radiating tube of diaphragm plate effect of having held concurrently below respectively, the hot gas outlet duct of inlet of cold air and opposite side is arranged at heat radiation group's body top, induced-draught fan is had in hot gas outlet duct, the radiating tube of many vertical parallel installations is had in heat radiation group body, every bar radiating tube there is the fin equidistantly tiltedly installed, heat radiation group body is fixedly connected with lower gas ash room, lower gas ash side, room has the ash disposal mouth of band wicket.
described upper smoke chamber, heat radiation group body are consistent with the cross section size and shape of lower gas ash room.
the installation gradient of described fin outside radiating tube is 20 °-35 °, and have radiating tube to bore a hole in the middle of fin, profile is leaf in the Three-blade fan reduced.
the bore of described heat smoke inlet tube and the chimney of shape and boiler supporting, hot gas outlet duct and induced-draught fan blast pipe supporting.
have spacing between midfeather lower side and lower location-plate in described heat radiation group body, this spacing is the air flue of blowing air.
the beneficial effects of the utility model are: this apparatus main body adopts split rotary type heat radiation group body, and in pipe, dust stratification removing is convenient, and heat exchanger effectiveness is high, air current flow parameter stability.Flue gas and the convection current of circulating air Zigzag type, extend the path together that heat exchange is carried out in convection current, in flue gas, ash easily deposition, reduces ash discharge capacity in an atmosphere.Fin is the single fan blade shape of electric fan, and in the outer oblique layout from level to level of radiating tube, area of dissipation is large, and smoothly, heat exchange is more abundant in circulation.
Accompanying drawing explanation
fig. 1 is the utility model agent structure schematic diagram.
fig. 2 is upper and lower positioning plate structure signal (overlooking) figure for square plate.
Detailed description of the invention
the utility model is also described in detail with reference to accompanying drawing below in conjunction with embodiment: see accompanying drawing, this gas-gas formula firewood boiler flue heat-exchange device, comprise flue and blower fan, heat smoke inlet tube 10 and warm smoke outlet tube 9 are placed in the top of main body, main body is followed successively by smoke chamber 8 from top to bottom, heat radiation group body 14 and lower gas ash room 1, upper smoke chamber and heat radiation group body are for being flexibly connected, there is a rotating shaft 5 between the two, rotating shaft offside has fastening screw 11, upper smoke chamber and the centre of dispelling the heat in group's body are all in conplane midfeather 13, heat radiation group body above with have location-plate 7 and lower location-plate 2 on the radiating tube of diaphragm plate effect of having held concurrently below respectively, the hot gas outlet duct 12 of inlet of cold air 6 and opposite side is arranged at heat radiation group's body top, induced-draught fan is had in hot gas outlet duct, the radiating tube 4 of many vertical parallel installations is had in heat radiation group body 14, every bar radiating tube 4 there is the fin 3 equidistantly tiltedly installed, heat radiation group body is fixedly connected with lower gas ash room, lower gas ash side, room has the ash disposal mouth 16 of band wicket.
described upper smoke chamber 8, heat radiation group body 14 are consistent with the cross section size and shape of lower gas ash room 1.
the installation gradient of described fin 3 outside radiating tube 4 is 20 °-35 °, and have radiating tube to bore a hole in the middle of fin, profile is leaf in the Three-blade fan reduced.
the bore of described heat smoke inlet tube 10 and the chimney of shape and boiler supporting, hot gas outlet duct 12 is supporting with induced-draught fan blast pipe.
have spacing between midfeather lower side and lower location-plate 2 in described heat radiation group body 14, this spacing is the air flue 15 of blowing air.
during the work of this device, first plug latch 11 at heat exchange section, shut the wicket of ash disposal mouth 16, then start blower fan, the heat smoke in boiler, on the right side of the upper smoke chamber 8 entering into main body from heat smoke inlet tube 10, the right side heat radiation group pipe of midfeather 13 in heat radiation group body 14, then to lower gas ash room 1, in the heat radiation group turned back on the left of midfeather manages, on the left of straight supreme smoke chamber, discharge through warm smoke outlet tube 9.While this process, cold air enters from inlet of cold air 6 and dispels the heat in group's body on the left of midfeather, fill in the space outside heat radiation group pipe, the installation direction of the fan-type blade outside every bar radiating tube is consistent with the main flow direction of air, namely the fin installation direction of midfeather left and right sides is contrary, the air flue 15 of passing through downwards under induced-draught fan effect above lower location-plate 2, go in the space of dispelling the heat outside group's pipe on the right side of midfeather, cold air is through two large spaces of turning back, manage with heat radiation group and oblique its outer fin that is arranged on fully contacts, the heat of heat smoke reach cold air the latter is become hot-air is sent from the hot gas outlet duct 12 on heat radiation group's body top, carry out heat energy utilization, complete gas-gas heat exchange.
when the more ash of group pipe inner product of dispelling the heat, extract the fastening screw 11 outside main body, heat radiation group body 14 is run up 90 ° together with the lower gas ash room 1 one below it, longitudinally insert in heat radiation group pipe with logical grey bar, disclose dust stratification one by one, dust stratification drops down onto lower gas ash room, dust stratification is discharged from the ash disposal mouth 16 of this room, then shut wicket, reverse 90 °, use again after plugging latch location after reset.
