Abstract
The utility model relates to a mixing device for gas pipeline delivery, which belongs to the technical field of fluid delivery mixing devices. The mixing device comprises an inner pipe and an outer pipe which are nested with each other, an outlet of the inner pipe is arranged in the outer pipe, and a cone expanding along the flowing direction of gas is arranged at the outlet. Flowing direction and flow rate of a gas flow jet from the inner pipe are changed by the cone arranged in the mixing device, and resistance loss of the gas flow is minimized, so that uniform mixing of gas in the inner pipe and gas in the outer pipe is realized and operation efficiency of equipment utilizing mixed gas is increased and operation cost thereof is reduced.
Description
Technical field
The utility model relates to a kind of the fluid of carrying is carried out the blended device in two pipeline, belongs to fluid and carries the mixing device technical field.
Background technology
In the actual production, often need the fluid of carrying in two pipelines be mixed.For example in iron and steel enterprise, adopt the hotblast stove of gas-fired will be in blast furnace gas blending coke-oven gas (also can be coal gas of converter), the characteristics of utilizing the coke-oven gas high heating value are to improve the efficiency of combustion and the ventilation temperature of hotblast stove.
Existing hotblast stove blending coke-oven gas in blast furnace gas generally is directly coke-oven gas to be sent into blast furnace gas pipeline by the air inlet adjustment valve, because blast furnace gas and coke-oven gas do not have abundant mixing in leading to the pipeline of Combustion of Hot Air Furnace chamber, cause that combustion gas causes that than unbalanced the Combustion of Hot Air Furnace chamber produces vibrations in combustion processes on the unit surface of combustion chamber.This vibrations make blast furnace gas (comprising coke-oven gas) pipeline and valve damage easily, cause serious consequence.
The producer that also has adopts so-called labyrinth type gas evenly mixing device, but the complex structure of this device, invest bigger, and maintenance cost height.
The utility model content
The technical problems to be solved in the utility model is to propose a kind of suiting the fluid of carrying in two pipelines (as gas) is carried out mixed uniformly device.
The technical solution of the utility model is: a kind of gas pipeline is carried evenly mixing device, comprises nested each other interior conduit and Outer Tube; The outlet of described interior conduit is positioned at Outer Tube, and is provided with along the cone of gas flow direction expansion in this exit.
So in use, when respectively by interior conduit and Outer Tube delivering gas, when the gas in the interior conduit during from the ejection of the exit of interior conduit, will be by the guiding of the cone in this exit and to evenly diffusion all around, just can be mixed fully by gas in the interior conduit that spreads, thereby realize gas uniform mixing in the inside and outside pipeline with the gas carried in the Outer Tube.
The beneficial effects of the utility model are: utilize hydromechanical principle, by using cone to change air motion direction and the flow velocity after the gas ejection in the pipeline, and make the drag losses minimum of air-flow, thereby realize in the pipeline uniform mixing of gas in the gas and another pipeline, and then improve the operational efficiency of the equipment that uses mixed gas and reduce running cost.
Improvement of the technical scheme is: described cone is a cone.
Further improvement in the technical proposal is: the awl point of described cone is 200～250cm apart from the distance of interior conduit outlet, and its maximum outside diameter is than the big 6～8cm of external diameter of interior conduit, and its cone angle is 120 °～130 °.
The further improvement of technique scheme is: the end of described cone maximum outside diameter is provided with flanging, is shaped on screw on the described flanging, and described cone is fixed on the periphery in interior conduit exit by the screw rod that passes described screw.
The perfect of technique scheme is: described interior conduit and Outer Tube remain on the same medullary ray.
Description of drawings
Carry evenly mixing device to be described further below in conjunction with accompanying drawing to gas pipeline of the present utility model.
Fig. 1 is that the gas pipeline of the utility model embodiment is carried the evenly mixing device structural representation.
Fig. 2 be among Fig. 1 A-A to sectional view.
Fig. 3 is the structural representation of cone among Fig. 1.
Embodiment
Embodiment
The gas pipeline of present embodiment is carried evenly mixing device as shown in Figure 1, comprises nested interior conduit 1 and Outer Tube 2; The outlet 3 of interior conduit 1 is positioned at Outer Tube 2, and exports 3 places at this and be provided with cone 4 along gas flow direction expansion.Interior conduit 1 and Outer Tube 2 remain on the same medullary ray.
As shown in Figure 1 and Figure 2, cone 4 is cones, and the awl of cone 4 point is relative with interior conduit 1 outlet 3, this awl sharp apart from interior conduit 1 export 3 be 200～250cm apart from S, so, best to the mixing effect of the gas channeling in the interior conduit 1 and interior conduit 1 gas and Outer Tube 2 gases.The maximum outside diameter of cone 4 has more 6～8cm than the external diameter of interior conduit 1, and helping in the interior conduit 1 gas like this derives by direction initialization.The end of cone 4 maximum outside diameters is provided with the wide flanging 6 of circle a 3～4cm, so that make screw 7 positions that are used for fixing cone 4 on flanging 6; Cone 4 is fixed on interior conduit 1 outlet 3 peripherys by three screw rods 5 that pass screw 7.
As shown in Figure 3, the cone angle of cone 4 (angle of α shown in Fig. 4) best results when being controlled at 120 °～130 °.
Obviously, the variation of carrying evenly mixing device to infer of the gas pipeline of present embodiment has: 1) cone 4 also can be triangle cone, square cone or other shape cones; 2) cone 4 also can directly be welded on interior conduit 1 outlet 3 peripherys, saves screw rod 5, flanging and screw; 3) interior conduit 1 and Outer Tube needn't remain on the same medullary ray; 4) screw rod 5 also can be two or many, is two at least.
Gas pipeline of the present utility model carries evenly mixing device to be not limited to the various embodiments described above, and all employings are equal to replaces the technical scheme that forms, and all drops on the protection domain of the utility model requirement.
