Abstract
The utility model discloses a hot air circulation device of a boiler. The hot air circulation device comprises the boiler, wherein the boiler is provided with a smoke outlet, the smoke outlet is connected with a chimney pipeline, the chimney pipeline is connected in series with a water tank for heating liquid water in the water tank, cooled smoke is divided into two branches, one branch of smoke is discharged outside through a chimney after being subjected to dust removal, and the other branch of smoke is introduced to the boiler through a recycling pipeline. The hot air circulation device provided by the utility model can be used for effectively increasing the energy utilization ratio through recycling higher-temperature hot air or smoke and directly introducing the smoke or hot air to the boiler and has the advantages of reasonable structure, realization of waste heat recycle and the like.
Description
Technical field
The utility model discloses a kind of boiler heated air circulation device, divides by International Patent Classification (IPC) (IPC) to belong to boiler smoke recycle device technical field.
Background technology
Boiler is to utilize fuel combustion to release energy; And be bound to produce flue gas during boiler combustion, it is reported that by statistical number the flue gas that boiler produces belongs to 170 degree~180 degree high-temperature gases; But existing boiler often directly is discharged into high-temperature flue gas in the air, waste flue gas energy stored.
Application number is that 201110089986.0 document discloses a kind of boiler afterheat recovery system; Include boiler, chimney is from the boiler outlet flue with to the flue collector of outlet of chimney; And the residual heat from boiler fume recover that wherein is provided with cooling water tank; Be connected with a bypass flue on the said flue collector, on this bypass flue, be serially connected with air-introduced machine and said residual heat from boiler fume recover, said boiler smoke is selected the switch valve that passes through being provided with on the said flue collector between said flue collector and said bypass flue; This recovery system complex structure becomes cost higher.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of rational in infrastructure, boiler heated air circulation device that waste heat recovery utilizes again.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of boiler heated air circulation device; Comprise boiler, this boiler has outlet flue, and outlet flue connects a chimney breast; Serial connection one water tank is to heat the liquid water in it on the chimney breast; The flue gas of cooling is divided into two branch roads, wherein discharges through chimney after the branch road dedusting, and another branch road is reclaim line and is passed in the boiler.
Further, described reclaim line is provided with air-introduced machine and enters into boiler raising fuel availability with guiding flue gas hot blast.
The utility model boiler heated air circulation device is that hot blast or the flue gas that temperature is higher recycled, and the supply boiler is to increase its efficiency of combustion.Traditional boiler; Generally be air blast to be set, directly be incorporated into outside air in the boiler combustion-supportingly that but outside air is when being cold wind at air inlet; Be unfavorable for effective utilization of boiler energy; And directly feed the flue gas hot blast, and can effectively improve capacity usage ratio in the time of combustion-supporting, have advantages such as rational in infrastructure, that waste heat recovery utilizes again.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 1, a kind of boiler heated air circulation device comprises boiler 1; This boiler has outlet flue, and outlet flue connects a chimney breast 2, and serial connection one water tank 3 is to heat the liquid water in it on the chimney breast; The flue gas of cooling is divided into two branch roads; Wherein discharge through chimney 5 after the branch road dedusting, another branch road is reclaim line 4 and is passed in the boiler that described reclaim line is provided with air-introduced machine and enters into the combustion rate that boiler improves fuel with guiding flue gas hot blast.
The utility model boiler heated air circulation device is that hot blast or the flue gas that temperature is higher recycled, and directly feeds the flue gas hot blast, can effectively improve capacity usage ratio in the time of combustion-supporting.
The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
