Abstract
It is a kind of efficiently more backhaul hot air boilers be related to boiler.Including furnace body, insulating layer, flue, burner hearth, coal filling hole, fire grate, cinder chamber, air inlet, hot-blast outlet and heat-exchanger rig.The heat-exchanger rig is multilayer sleeve between insulating layer of furnace body inner wall and flue, within sleeve, the outer wall of outer wall and flue be equipped with several radiating fins, sleeve upper and lower side is equipped with backhaul mouth.The utility model has the advantages that the utility model is additionally arranged inside and outside 2 layers of sleeve around flue caused by the utility model, sleeve inside and outside wall is equipped with several radiating fins, air blower is through air inlet air blast, heat exchanging interlayer first between outer sleeve 16 and insulating layer inner wall 3 rises, it is turned back to top by top backhaul mouth 18 into the heat radiation sandwich layer between inner and outer sleeves, enter the heat exchanging interlayer constituted between inner sleeve and flue through bottom backhaul mouth 19 to bottom, it turns back through multiple backhaul and generates heat exchange with radiating fin, path length, heat exchange is abundant, and the energy saving thermal efficiency is high.
Description
Technical field:
The utility model relates to hot air boilers.
Background technique:
Existing hot air boiler majority is the furnace gall periphery periphery for allowing cold air to flow through equipped with radiating fin, the combustion of flue combustion chamber
Burn the heat generated, by flue and its welding several radiating fins thereon, carry out heat exchange with cold air, by cold air plus
Heat is blown out in the form of hot wind at hot-air, provides external air heating.Its defect is that heat exchange path is short, and heat exchange is not
Sufficiently, waste of energy.
Utility model content:
The purpose of the utility model is to provide a kind of efficiently more backhaul hot air boilers, its heat exchange path is long, energy-efficient,
Using effect is good.
The utility model is so to implement: a kind of efficiently more backhaul hot air boilers, including furnace body 1, insulating layer 2, insulating layer
Inner wall 3, flue 4, burner hearth 5, coal filling hole 8, fire grate 6, cinder chamber 7, cinder chamber's door 7 ', air blower 13, air inlet 12, hot-blast outlet
14 and heat-exchanger rig.The heat-exchanger rig is multilayer sleeve 9 between insulating layer of furnace body inner wall 3 and flue 4, sleeve 9 it
The outer wall of inside and outside wall and flue 4 is equipped with several radiating fins 10, and sleeve upper and lower side is equipped with backhaul mouth.
The utility model is it may further be preferable that the multilayer sleeve 9 includes outer sleeve 16 and 17 2 layers of inner sleeve set
Cylinder, outer sleeve top are equipped with upper backhaul mouth 18, and inner sleeve bottom end is equipped with lower backhaul mouth 19.Between inner and outer sleeves, outer sleeve
It is configured to heat exchanging interlayer 11 between 16 and insulating layer inner wall 3, between inner sleeve 17 and flue 4.Air inlet 12 connects outer sleeve 16
Heat exchanging interlayer bottom end between insulating layer inner wall 3.
Caused by the utility model the utility model has the advantages that
The utility model is additionally arranged inside and outside 2 layers of sleeve around flue, and sleeve inside and outside wall is equipped with several radiating fins, air blast
Machine is through air inlet air blast, and the heat exchanging interlayer first between outer sleeve 16 and insulating layer inner wall 3 rises, until top is by top backhaul
Mouthfuls 18 turn back into the heat radiation sandwich layer between inside and outside sleeve, until bottom through bottom backhaul mouth 19 enter inner sleeve 17 and flue 4 it
Between heat exchanging interlayer, so through multiple backhaul turn back and radiating fin generate heat exchange, path length, heat exchange is abundant, energy conservation heat
It is high-efficient.
Detailed description of the invention:
1 the utility model of attached drawing constructs main view
Specific embodiment:
It is described further below in conjunction with aufbauprinciple of the attached drawing to the utility model.
Efficiently more backhaul hot air boilers, including furnace body 1, insulating layer 2, insulating layer inner wall 3, flue 4, burner hearth 5, coal filling hole
8, fire grate 6, cinder chamber 7, cinder chamber's door 7 ', air blower 13, air inlet 12, hot-blast outlet 14 and heat-exchanger rig.Heat-exchanger rig is
Multilayer sleeve 9 between insulating layer of furnace body inner wall 3 and flue 4, within sleeve 9, the outer wall of outer wall and flue 4 is equipped with
Several radiating fins 10, sleeve upper and lower side are equipped with backhaul mouth.The multilayer sleeve 9 includes outer sleeve 16 and 17 2 layers of inner sleeve set
Cylinder, outer sleeve top are equipped with upper backhaul mouth 18, and inner sleeve bottom end is equipped with lower backhaul mouth 19.Between inner and outer sleeves, outer sleeve
Between 16 and insulating layer inner wall 3, heat exchanging interlayer 11 is constituted between inner sleeve 17 and flue 4.Air inlet 12 connect outer sleeve 16 with
Heat exchanging interlayer bottom end between insulating layer inner wall 3.For this hot-blast stove by 8 coal of coal filling hole, flue is slightly tapered, the cigarette for generation of burning
Gas rises, and is discharged through furnace roof portion chimney.
