Abstract
The invention discloses an efficient air mixing device for sintering flue gas circulation. The efficient air mixing device comprises an air mixing device shell. A mixed air outlet is formed in one side of the air mixing device shell, and the other side of the air mixing device shell is communicated with a hot air pipe. The hot air pipe is sleeved with a spiral cold air coil, and the two ends of the cold air coil are the air inlet end and the air outlet end respectively. The air outlet end is communicated with the interior of the air mixing device shell through a through hole. According to the efficient air mixing device for sintering flue gas circulation, cold air can enter the air mixing device shell in a high-speed rotational flow state so that the cold air can be rapidly and evenly mixed with high-temperature flue gas. Thus, the purpose of stabilizing the temperature of the flue gas is achieved, continuity of sintering production is ensured, the production efficiency of a sintering machine is improved, and the effects of energy conservation and emission reduction are achieved.
Description
Technical field
The present invention relates to a kind of sinter fume EGR, 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.
Summary of the invention
The object of this invention is to provide a kind of sinter fume to circulate efficient air mixing device, can solve the problem.
The present invention 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 object of the present invention 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 invention has the advantages that: 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.

Detailed description of the invention
Sinter fume of the present invention 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 invention 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 stablizing the object of 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 present invention promotes 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 present invention 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 present invention improves 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.
