Description
Technical field
The utility model relates to eddy current pipeline technical field, is specifically related to a kind of spiral rectification and accelerates pipeline.
Background technique
Pipeline is for carrying the fluids such as gas, liquid or gas-liquid mixed, and the application in the field such as water power, chemical industry is all quite extensive, and the flowing state of fluid in pipeline can be divided into laminar flow, transition flow and turbulent flow according to flow velocity.Laminar flow refers to when flow velocity is very little, and fluid layering flows, and mutual unmixed flowing state, also referred to as current stabilization or sheet stream; Transition flow refers to when flow velocity is larger, and the streamline of fluid starts the flowing state occurring wavy swing, its swing frequency and amplitude flow velocity increase and increase; Turbulent flow refers to when flow velocity is increased to very large, streamline is no longer clear can be distinguished, many little whirlpools are had in flow field, the state that laminar flow is destroyed, at this moment adjacent flow interlayer not only has slip, also has mixing, at this moment fluid does irrgular movement, have the component velocity perpendicular to stream tube axis direction to produce, this motion is called turbulent flow, is also called sinuous flow, flow-disturbing or turbulent flow.Therefore, can lose mechanical energy by the impact of self flowing state when fluid flows in pipeline, especially for the fluid being in turbulence state, its mechanical power loss is larger, causes fluid to produce larger pressure drop in the duct, thus reduces flow velocity.
Traditional, people improve the kinetic energy of fluid by increasing transmission power, thus when keeping fluid to flow to pipe end, still there is larger flow velocity, along with the maturation of this scheme, it is found that continuing through the mode increasing transmission power becomes more and more difficult to the flow velocity improving pipe end fluid, be therefore necessary to provide a kind of newly, easy speeding scheme realized.Patent CN 103277370 A proposes the scheme arranging spiral catch in the duct, and convection cell serves the effect of acceleration, but after adopting its scheme, rate of flow of fluid increase is no more than 5%, and acceleration effect is not obvious.Researcher is studied on this basis, and can expect according to those skilled in the art, researcher finds can not play comparatively significant acceleration effect by increase spiral catch number and this conventional substitute mode of length, therefore, need to realize by other means accelerating largely.
Model utility content
For solving above technical problem, the utility model provides a kind of spiral rectification to accelerate pipeline.
Technological scheme is as follows:
Pipeline is accelerated in a kind of spiral rectification, its key is: comprise pipeline body, be connected with guiding at the inwall of this pipeline body and accelerate sheet, it is internal thread shape that described guiding accelerates sheet, the starting point that described guiding accelerates sheet is positioned at the entrance of described pipeline body, the end that described guiding accelerates sheet is positioned at the outlet section of described pipeline body, and the lead angle of described guiding acceleration sheet from large to small, is provided with rectifier at the entry end of described pipeline body from its starting point.
The remarkable result of above technological scheme is, fluid enters from the entry end of pipeline body, rectifier plays rectified action to the fluid in pipeline, screw-shaped guiding is accelerated sheet and is played guiding acceleration to the fluid in pipeline, it is more regular that rectifier makes fluid flow, and improves the acceleration effect that guiding accelerates sheet convection cell, and rectifier and guiding accelerate sheet coordinated, the acceleration effect of convection cell is obvious, and flow velocity increases by more than 10%.
In order to better realize the utility model, may further be:
Above-mentioned rectifier is made up of four pieces of flow distribution plates, the inner side edge of four pieces of described flow distribution plates is connected, in cross after four pieces of described flow distribution plates connect, center line after four pieces of described flow distribution plates connect overlaps with the tube core line of described pipeline body, and the outer side of four pieces of described flow distribution plates is all affixed with the inwall of described pipeline body.Use this technological scheme, cross rectifier is by fluid well-distributing segmentation in four parts, and the rectification effect of convection cell is best, and the castering action of fluid flow rate is obvious.
The height that above-mentioned guiding accelerates sheet increases by zero s gradually from its starting point, and the inner side of this guiding acceleration sheet is less than or equal to 1/2 radius of described pipeline body to the distance of described pipeline body tube core line.Adopt the program, can improve the flow velocity of fluid further, flow velocity increases about 2% further.

Above-mentioned guiding is accelerated sheet and is at least two, and described guiding accelerates spaced set between sheet.Adopt the program, can improve the flow velocity of fluid further, flow velocity increases about 1% further.
It is one-body molded that above-mentioned guiding accelerates sheet, rectifier and pipeline body.Adopt the program, guiding accelerates the making of sheet, rectifier and pipeline body more for convenience.
Below in conjunction with test example, the utility model is described in further detail.
