Description
Technical field
The present invention relates to a kind of fluid control devices, particularly a kind of radial gas rectifier, belong 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 designed 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 the traditional axial gas rectifier of layout 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.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of radial gas rectifier that adapts to the radial air inlet mode and can effectively eliminate import distortion flow interference.
The technical solution adopted in the present invention is:
A kind of radial gas rectifier, comprise 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; Have a plurality of rectification hole on the outer wall of the Outer Tube surrounded by outer ring cavity, the gross area of rectification hole is less than the cross-section area of suction port.
Technical characteristics of the present invention also is: when suction port quantity is two when above, suction port is along circumferentially being uniformly distributed; The suction port sectional shape is circular or square.
In technique scheme, described outer ring plate is pipe, square tube or Taper Pipe; The rectification hole sectional shape is circular, square or line of rabbet joint shape.
The present invention has the following advantages with respect to prior art and the technique effect of high-lighting: the present invention can realize 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 present invention is advantage simple in structure, with low cost in addition simultaneously.

Description of reference numerals is as follows: the 1-suction port; The 2-end plate; The 3-outlet; The 4-interior conduit; The outer ring cavity of 5-; Ring cavity in 6-; The 7-Outer Tube; The 8-rectification hole; The 9-outer ring plate; The 10-front screen; The 11-backboard; The 101-inlet stream; 102-stays whirlpool; 103-is through the air-flow of rectification hole; Air-flow after the 104-rectification.
Embodiment
Below in conjunction with the drawings and specific embodiments, structure of the present invention, principle and concrete enforcement are described further.
As shown in Figure 1 and Figure 2, radial gas rectifier provided by the invention 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; Have a plurality of rectification hole on the outer wall of the Outer Tube that ring cavity surrounds outside, 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 two when above, suction port 1 is along circumferentially being uniformly distributed; 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 invention and working procedure are as follows:
At 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 the circumferential flow of less outer ring cavity 5 along resistance at first, thereby reaches at the water conservancy diversion that makes progress in week, improves the function of the circumferential air-flow uniformity.Air-flow radially enters interior ring cavity 6 through rectification hole 8, and the 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 different and variations to some extent of the aerodynamic parameter of the air-flow 103 through rectification hole 8, 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; Simultaneously, the existence of outer ring cavity 5, interior ring cavity 6 and rectification hole 8, make rectifier can play the effect in helmholtz resonance chamber, the function that can play weakening, absorb the vibration of characteristic frequency.
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 the edge, outlet, the core of local high-speed region or close interior conduit outer wall, or near the Outer Tube internal face, and the velocity gradient between adjacent core also has larger zone, the uniformity of whole exit flow field is poor.
Fig. 4 is the outlet speed cloud atlas that the radial gas rectifier is arranged in the present invention.As seen from Figure 4, high velocity concentrates on the 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.
