Description
Technical field
The utility model relates to a kind of fluid control devices, and particularly a kind of radial gas rectifier, belongs to fluid flow control apparatus technical field.
Background technique
Traditional gasotron is divided into two kinds of tabular and sheets, these two kinds of rectifiers be widely used in gas water conservancy diversion, eliminate vortex and the distribution of regulating the speed; But current gasotron is the axial rectifier designing for circle or square pipe mostly, and for ring cavity or square lumen road, the gasotron of the cavity that especially inside and outside chamber interplanar distance is less is less.The latter, because inside and outside chamber interplanar distance is less, is difficult to arrange traditional axial gas rectifier in runner on the one hand, and what it adopted on the other hand is scarcely also traditional axial admission mode, but the intake method of one or more radial direction.This one or more radial air inlet mode, the gas that has determined to enter cavity is upwards inhomogeneous in week from the beginning, if each suction port aerodynamic parameter has difference, air-flow upwards even has larger distortion in week.If therefore in the radial direction without gasotron, and pipeline axial length is more in short-term, be difficult to guarantee cavity exit gas aerodynamic parameter evenly.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of radial gas rectifier that adapts to radial air inlet mode and can effectively eliminate import distortion flow interference.
The technological scheme that the utility model adopts is:
A radial gas rectifier, comprises at least one suction port, Outer Tube, interior conduit and end plate, described Outer Tube inwall, and ring cavity in end plate and interior conduit outer wall surround and form, is characterized in that: end plate, outer ring plate, front screen, backboard; Outer ring plate, front screen, backboard and Outer Tube outer wall surround an outer ring cavity jointly; Described suction port is arranged on outer ring plate, and communicates with outer ring cavity; In the outer wall of the Outer Tube being surrounded by outer ring cavity, have a plurality of rectification hole, the gross area of rectification hole is less than the cross-section area of suction port.
Technical characteristics of the present utility model is also: when suction port quantity is when more than two, suction port is uniformly distributed circumferentially; Suction port sectional shape is circular or square.
In technique scheme, described outer ring plate is pipe, square tube or Taper Pipe; Rectification hole sectional shape is circular, square or line of rabbet joint shape.
The utility model has the following advantages with respect to prior art and the technique effect of high-lighting: the utility model can be realized gas water conservancy diversion, rectification function diametrically, can effectively eliminate import distortion flow interference, and have the function of certain weakening, the vibration of absorption characteristic frequency concurrently.The utility model is advantage simple in structure, with low cost in addition simultaneously.

Embodiment
Below in conjunction with the drawings and specific embodiments, structure of the present utility model, principle and concrete enforcement are described further.
As shown in Figure 1 and Figure 2, the radial gas rectifier that the utility model provides comprises suction port 1, Outer Tube 7, interior conduit 4, end plate 2, outer ring plate 9, front screen 10 and backboard 11; Ring cavity 6 in the inwall of Outer Tube, the outer wall of interior conduit and end plate 2 surround and form; The outer wall of outer ring plate 9, front screen 10, backboard 11 and Outer Tube 7 surrounds an outer ring cavity 5 jointly; Described suction port 1 is arranged on outer ring plate 9, and communicates with outer ring cavity 5; In the outer wall of the Outer Tube that ring cavity surrounds outside, have a plurality of rectification hole, the gross area of rectification hole should be less than the cross-section area of suction port.The cross-section area of suction port 1 should be less than the section area of outer ring cavity 5.
Described suction port 1 can adopt one or more, and when suction port quantity is when more than two, suction port 1 is uniformly distributed circumferentially; Suction port 1 sectional shape is circular or square.Outer ring plate 9 can adopt pipe, square tube or Taper Pipe; The sectional shape of rectification hole 8 can adopt circle, square or line of rabbet joint shape.
Working mechanism of the present utility model and working procedure are as follows:
First inlet stream 101 enters outer ring cavity 5 by suction port 1, then through rectification hole 8, radially enters interior ring cavity 6; Because the gross area of rectification hole is less than the cross-section area of suction port, the resistance that air-flow enters interior ring cavity 6 by rectification hole 8 is larger, therefore air-flow is first along the circumferential flow of the less outer ring cavity 5 of resistance, thereby reach at the water conservancy diversion that makes progress in week, improve the function of the circumferential air-flow uniformity.Air-flow radially enters interior ring cavity 6 through rectification hole 8, and part air-flow is forming and staying whirlpool 102 near end plate 2 places, and the air-flow 104 after rectification flows to outlet 3 directions.The intensity of staying whirlpool 102 and action range can be along with the aerodynamic parameter of the air-flow 103 through rectification hole 8 different and variation to some extent, this has just formed a kind of self adaption on pneumatic, further improve air-flow in the circumferential uniformity, and can eliminate the interference of import distortion fluid; Meanwhile, the existence of outer ring cavity 5, interior ring cavity 6 and rectification hole 8, makes rectifier can play the effect in helmholtz resonance chamber, the function that can the vibration of characteristic frequency be played weakening, be absorbed.
Fig. 3 is without the outlet speed cloud atlas of radial gas rectifier in prior art.As shown in Figure 3, circumferentially there are a plurality of local high-speed regions in edge, outlet, the core of local high-speed region or close interior conduit outer wall, or near Outer Tube internal face, and the velocity gradient between adjacent core also has larger region, the uniformity of whole exit flow field is poor.
Fig. 4 is the outlet speed cloud atlas that has radial gas rectifier in the utility model.As seen from Figure 4, high velocity concentrates on ring cavity middle part, less along circumferential velocity gradient, and does not occur as the local high-speed region in Fig. 3, and the uniformity of whole exit flow field is better.
