Abstract
The utility model belongs to the technical field of fluid control equipment, and relates to the technical field of equipment for controlling flowing patterns of gas, in particular to an air current rectifier. The air current direction at an outlet of the air current rectifier is adjusted, the air current speed at the outlet of the air current rectifier is adjusted at the same time, and pressure loss caused by overlarge flow resistance can also be avoided. According to the technical scheme, the air current rectifier comprises a pipeline and the outlet, wherein an inlet end board is arranged at an inlet of the pipeline, a plurality of air inlet pipes are evenly distributed on the inlet end board in an annular mode, a cocurrent cone is arranged on the inner side of the middle of the inlet end board and is of a cone structure, the bottom end of the cocurrent cone is fixedly connected to the inlet end board, the inlet pipes are located on the periphery of the bottom end of the cucurrent cone, and a rectifying board is arranged in the middle of the pipeline and is provided with small holes. The air current rectifier reduces gas flow in the center of the rectifier, and avoids multi-path currents from being mixed and producing the vortex street phenomenon.
Description
Technical field
The utility model belongs to the control apparatus technical field of fluid control apparatus technical field, particularly gas flow form, specifically is a kind of air-flow rectifier.
Background technique
The air-flow rectifier is used for import is entered the flowing gas state of gasotron to be adjusted, and obtains satisfied stream condition in the outlet of gasotron.Existing air-flow rectifier generally all is made up of a pipeline, one or two water conservancy diversion unit, a gas outlet and a gas inlet.The air-flow rectifier of this structure is only adjusted the direction of air-flow, distribution to exit flow is not adjusted, find in actual the use, owing between tube wall and the gas friction is arranged, and gas has the characteristic of certain viscosity, so a problem has appearred in existing air-flow rectifier, the middle flow velocity maximum of exit flow, more slow the closer to the tube wall gas flow rate, and at pipe diameter more hour, this phenomenon is more obvious.In order to address this problem, the way that damping net is set at pipeline is arranged, though this solution can solve air-flow and even problem, but bring the very big pressure loss because of meeting.Increased the energy consumption of system so on the one hand, the pressure loss increases the demand that needs higher inlet pressure could satisfy outlet pressure on the other hand, possibly can't satisfy the demand of outlet pressure under the limited condition of the inlet pressure upper limit.
The model utility content:
The utility model will provide a kind of air-flow rectifier, adjusts the distribution of air-flow rectifier exit flow speed when adjusting air-flow rectifier exit flow direction, simultaneously the pressure loss that also can avoid excessive flow resistance to cause.
For overcoming the problem that prior art exists, the technological scheme that the utility model provides is: a kind of air-flow rectifier, comprise pipeline and outlet, it is characterized in that: the inlet of described pipeline is provided with sheet inlet, ring is established and is evenly equipped with some suction tude on the sheet inlet, and inboard, sheet inlet middle part is provided with the interflow awl, and described interflow awl is cone structure, its bottom is fixed on the sheet inlet, and suction tude is positioned at awl periphery, bottom, interflow; The middle part of described pipeline is provided with current plate, and current plate is provided with aperture, and the thickness of current plate is greater than 2 times of hole diameter, and is solid construction corresponding to the circumference at place, some suction tude center of circle.
The cone-apex angle of above-mentioned interflow awl is between 20-50 °.
Above-mentioned current plate is near sheet inlet one side.Can eliminate current plate to the bad interference of air-flow.
The distribution form of above-mentioned aperture is that equilateral triangle is arranged.
Compared with prior art, the utility model has the advantages that:
1, a plurality of airflow inlets of even distribution type have reduced rectifier central gas flow, and the interflow awl because arranging avoids the multichannel air-flow to mix and generation vortex street phenomenon simultaneously; Current plate can further be adjusted and mixing air-flow.
2, air-flow and even: exit flow speed ratio of minimum flow velocity and Peak Flow Rate in the radius of outlet size 1/2 can reach more than 75%.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the structural representation of current plate.
Description of reference numerals is as follows:
1-pipeline, 2-current plate, 3-collaborate awl, 4-airflow inlet, 5-sheet inlet, 6-outlet, 7-aperture.
Embodiment:
Describe in detail below in conjunction with 1 pair of the utility model of accompanying drawing.
A kind of air-flow rectifier, comprise pipeline 1 and outlet 6, the inlet of described pipeline 1 is provided with sheet inlet 5, ring is established and is evenly equipped with some suction tude 4 on the sheet inlet 5, inboard, sheet inlet middle part is provided with interflow awl 3, described interflow awl 3 is cone structure, and its bottom is fixed on the sheet inlet, and suction tude 4 is positioned at awl periphery, 3 bottom, interflow; The middle part of described pipeline is provided with current plate 2, and current plate 2 is provided with aperture 7, and the distribution form of described aperture 7 is that equilateral triangle is arranged.The thickness of current plate 2 for example is 2.2 times of hole diameter greater than 2 times of hole diameter, and is solid construction corresponding to the circumference at place, some suction tude 4 center of circle, and that is to say on the imaginary line corresponding to place, some suction tude 4 center of circle circumference does not have aperture 7 to arrange.The cone-apex angle of described interflow awl 3 is 30 degree.
During use, the suction tude 4 of air-flow on sheet inlet 5 enters pipeline 1, because the barrier effect of interflow awl 3, air-flow can progress into the central position, just can not produce the vortex street phenomenon yet, and then air-flow is passed by the aperture 7 on the current plate 2, because the rectified action of 7 pairs of air-flows of aperture, the further adjustment of air-flow and mixing are also discharged from exporting 6.
