Description
Technical field
The utility model relates to a kind of hot-blast stove.
Background technology
The bottom that existing hot-blast stove comprises hot-blast stove side is provided with combustion furnace, and opposite side arranges heat-exchanger rig and comprises heat exchange pipeline, cold wind import, air exhauster.Air outside hot-blast stove is with this by air exhauster, and cold wind import enters heat exchange pipeline; The hot flue gases that combustion furnace burning produces contacts with heat exchange pipeline and carries out heat exchange, and the flue gas outlet of flue gas above shaft completing heat exchange is discharged, and the cold air through heat exchange leaves from hot-blast outlet.
The deficiencies in the prior art are, due to hot flue gases and heat exchange pipeline shorter for time of contact, the insufficient heat transfer effect that causes of heat exchange is bad, there is the problem of the wasting of resources.In addition enter in the air of heat exchange pipeline and be mingled with dust, easily in heat exchange pipeline, make dust be attached to inner-walls of duct, thus affecting heat transfer effect.
And hot flue gases is also with volume of smoke, can be attached to heat exchanger tube outer wall in heat transfer process affects heat transfer effect, and the flue gas of simultaneously discharging with dust also can be pollute for environment.
Utility model content
Technical problem to be solved in the utility model is to provide one and can extends the comes into heat transferring contact time thus make heat exchange more abundant, greatly improves heat exchange efficiency, reduces the hot-blast stove for heat transfer effect and atmosphere environment impact of dust in gas simultaneously.
In order to solve the problem, the hot-blast stove that the utility model provides, the bottom being included in hot-blast stove side is provided with combustion furnace, and combustion furnace burning produces high-temperature hot flue gas.Above combustion furnace, a dividing plate is set at a distance of a segment distance, the space above combustion furnace is divided into substantially equal two parts.Hot-blast stove opposite side vertically arranges some heat exchange pipelines, alternately between heat exchange pipeline arranges several dividing plates, substantially shining right pipeline is divided into uniform a few part, forms the S shape gas circuit of above-below direction, thus extend heat exchange distance.On the right side of heat exchange pipeline port successively with cold wind import, air exhauster be connected.Hot-blast stove shaft top and bottom are respectively arranged with cleaning door.Shaft back side is provided with flue gas outlet, and above combustion furnace, shaft front arranges hot-blast outlet.
Preferred scheme is that cold wind import is provided with air filter further, treats that the air of heat exchange carries out dust removal and filtration for suction, and the dust that minimizing air is brought into is attached to heat exchange pipeline inwall, affects heat transfer effect.
Preferred scheme arranges air filter at flue gas outlet further, carries out filtering reduce its impact for environment to the flue gas of discharging.
Further preferred scheme is that shaft top arranges a cleaning door, the width of described cleaning door be slightly less than the projection of air refreshing tube in bottom surface with guarantee with when water flush clean heat exchange pipeline and hot-blast stove inwall substantially without dead angle, clean thorough.The cleaning door arranged below shaft with the sewage of dust after completing deashing flows out.
The technique effect of utility model: (1) adds the time of contact of high-temperature flue gas and cold air, makes its abundant heat exchange, improves heat utilization ratio.(2) decrease the dust that cold air brings into and be attached to inner-walls of duct, thus improve heat transfer effect.(3) flue gas outlet arranges filter and will lack the pollution of waste gas for air.
Accompanying drawing explanation
Below in conjunction with Figure of description, the utility model is described in further detail:
Fig. 1 is the vertical section structure schematic diagram of hot-blast stove of the present utility model.
Fig. 2 is the cross-sectional structure schematic diagram of hot-blast stove of the present utility model.
Shaft 1, combustion furnace 2, dividing plate 3, air exhauster 4, cold wind import 5, heat exchange pipeline 6, flue gas outlet 7, hot-blast outlet 8, the first baffle plate 9, second plate washer 10, third gear plate 11, fourth speed plate 12, cleaning door 13.
Detailed description of the invention
Embodiment 1 as Fig. 1, the hot-blast stove of the present embodiment, it comprises: the bottom of hot-blast stove shaft 1 side is provided with combustion furnace 2, arranges a dividing plate 3 at a distance of a segment distance, the space above combustion furnace is divided into substantially equal two parts above combustion furnace; Hot-blast stove opposite side vertically arranges some heat exchange pipelines 6, alternately between heat exchange pipeline arranges four dividing plates, substantially shining right pipeline is divided into uniform four parts; On the right side of heat exchange pipeline port successively with cold wind import 5, air exhauster 4 is connected; Hot-blast stove shaft 1 top and bottom are respectively arranged with cleaning door 13, described in be arranged on the cleaning door 13 at shaft 1 top width be slightly less than the projection of air refreshing tube in bottom surface; Shaft back side is provided with flue gas outlet 7; Above combustion furnace 2, shaft front arranges hot-blast outlet 8; Cold wind import 5 is provided with air filter; At flue gas outlet 7, air filter is set.The side, bottom of the first baffle plate 9 is provided with the neutral entered for flue gas, and top is provided with the outlet passed through for hot blast.Second plate washer 10 top is provided with the neutral of supplied gas flowing.Third gear plate 11 fourth speed plate 12 size is all less than shaft sectional dimension and circulates to make flue gas.
During work, cold air is successively by air exhauster 4, and cold wind import 5 and air filter, wriggle in the middle part of cold wind import side to shaft along heat exchange pipeline about 6; The high-temperature flue gas that combustion furnace 2 burning produces enters from the neutral below the first plate washer 8 heat-exchanger rig arranging intensive heat exchange pipeline 6, flue gas is due to the effect of four pieces of baffle plates, the S shape gas circuit flowing of above-below direction is pressed in shaft, extend heat exchange distance, thus add the time of contact with heat exchange pipeline 6, make heat exchange more abundant.Complete the flue gas of heat transfer process successively through air cleaner, flue gas outlet 7 discharges out of the furnace.Air through heat exchange is left by the hot-blast outlet 8 being arranged on shaft front.
During deashing, open the cleaning door 13 at shaft top, with scour without sediment motion heat exchange pipeline 6 and shaft inwall, the sewage of band dust is flowed out by two cleaning doors 13 being arranged on restoration of lower stack subsequently, completes deashing.
