Abstract
High -efficient wind device that mixes of sintering flue gas recirculation, including mixing wind device casing, one side of muddy wind device casing sets up the export of mixed wind, mixes the opposite side and hot -blast main intercommunication of wind device casing, and it has spiral helicine cold wind coil pipe to overlap on the hot -blast main, and cold wind coil pipe both ends are air inlet end and air -out end respectively, and the air -out end communicates with each other with muddy wind device casing is inside through the through -hole. The utility model discloses can make cold wind be high -speed whirl state and get into mix wind device casing, make cold wind can with the quick homogeneous mixing of high temperature flue gas to the purpose of flue -gas temperature is stabilized in the realization, has guaranteed the continuity of sintering production, has improved sintering machine production efficiency, realizes energy saving and emission reduction's effect.
Description
Technical field
The utility model relates to a kind of sinter fume EGR, and specifically a kind of sinter fume circulates efficient air mixing device.
Background technology
Current domestic each sintering plant is more and more higher for the requirement of energy-saving and emission-reduction, new requirement is proposed to sintering technology development, for realizing energy-saving and emission-reduction, high temperature oxygen gas in large flue in sintering machine production process need be circulated in sintering device flue gas circulation cover and participate in sintering process, therefore the temperature of circulating flue gas controls to seem particularly important, and current existing circulating flue gas air mixing device is difficult to guarantee the rapid Homogeneous phase mixing of cold-hot wind, cause the temperature fluctuation range of circulating flue gas larger, often exceed the temperature range of regulation, therefore the continuity ensureing SINTERING PRODUCTION is difficult to, affect the production efficiency of sintering machine and the effect of energy-saving and emission-reduction.
Utility model content
The purpose of this utility model is to provide a kind of sinter fume and circulates efficient air mixing device, can solve the problem.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of sinter fume circulates efficient air mixing device, comprise air mixing device housing, the side of air mixing device housing arranges the outlet of mixing wind, the opposite side of air mixing device housing is communicated with warm-air pipe, on warm-air pipe, cover has spiral helicine cold wind coil pipe, and cold wind coil pipe two ends are respectively air intake and outlet air end, and outlet air end is communicated with air mixing device enclosure interior by through hole.
In order to realize the purpose of this utility model further, can also by the following technical solutions: the inside mounting and fixing support of described air mixing device housing, fixed mount is installed hot blast diversion shell, hot blast diversion shell is conical shell, the tip of hot blast diversion shell is towards warm-air pipe, and the axis of diversion shell overlaps with the axis of warm-air pipe.Arrange kuppe between described air mixing device housing and the outlet of mixing wind, the nearer outside internal diameter in side of kuppe distance air mixing device housing reduces gradually.The diameter of described cold wind coil pipe is reduced to outlet air end gradually by air intake.
The utility model has the advantage of: cold wind can be made to be that high-speed rotational state enters air mixing device housing, cold wind can be mixed with high-temperature flue gas Quick uniform, thus realize the object stablizing flue-gas temperature, ensure the continuity of SINTERING PRODUCTION, improve sintering machine production efficiency, strengthen the effect etc. of energy-saving and emission-reduction.

Mark illustrates: 1 warm-air pipe 3 cold wind coil pipe 4 hot blast diversion shell 5 air mixing device housing 6 kuppe 7 mixes wind and exports 8 fixed mount 9 air intake 10 outlet air end 11 through holes.
Detailed description of the invention
Sinter fume described in the utility model circulates efficient air mixing device, as shown in Figure 1, Figure 2 and Figure 3, comprise air mixing device housing 5, the side of air mixing device housing 5 arranges mixing wind outlet 7, the opposite side of air mixing device housing 5 is communicated with warm-air pipe 1, on warm-air pipe 1, cover has spiral helicine cold wind coil pipe 3, and cold wind coil pipe 3 two ends are respectively air intake 9 and outlet air end 10, and outlet air end 10 is communicated with air mixing device housing 5 inside by through hole 11.Cold wind coil pipe 3 of the present utility model can make cold wind be that high-speed rotational state enters air mixing device housing 5, make cold wind can with high-temperature flue gas rapid mixing, thus realize the object stablizing flue-gas temperature, ensure that the continuity of SINTERING PRODUCTION, improve sintering machine production efficiency, realize the effect of energy-saving and emission-reduction.
The utility model is promote cold-hot wind mixing rate further, can at the inside mounting and fixing support 8 of described air mixing device housing 5, fixed mount 8 is installed hot blast diversion shell 4, hot blast diversion shell 4 is conical shell, the tip of hot blast diversion shell 4 is towards warm-air pipe 1, and the axis of diversion shell 4 overlaps with the axis of warm-air pipe 1.Hot blast is shunted to hot blast diversion shell 4 edge by hot blast diversion shell 4 when hot blast diversion shell 4, and hot blast is initiatively mixed with the cold wind of high-speed rotational state.
The utility model is to mixed circulated air compression polymerization, can arrange kuppe 6 between described air mixing device housing 5 and mixing wind outlet 7, and the kuppe 6 side outside internal diameter nearer apart from air mixing device housing 5 reduces gradually.Kuppe 6 can eliminate the area of low pressure at the circulated air center of eddy flow state, makes to enter the circulated air pressure stability in sintering machine circulation cover.
The utility model is improve wind speed when cold wind enters air mixing device housing 5, is reduced gradually by the diameter of described cold wind coil pipe 3 by air intake 9 to outlet air end 10.This structure can further promote cold-hot wind mixing rate.
