Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description so that advantages of the present invention and
Feature can be easier to be readily appreciated by one skilled in the art, to make apparent specific boundary to protection scope of the present invention
It is fixed.
One kind of the present invention can secondary mixed Venturi tube, including it is Venturi tube 1, secondary mixing ejector pipe a2, secondary mixed
Close ejector pipe b3, secondary mixing ejector pipe c4 and secondary mixing ejector pipe d5.By taking secondary mixing ejector pipe a2 as an example, secondary mixing
Ejector pipe b3, secondary mixing ejector pipe c4, secondary mixing ejector pipe d5 are identical with the secondary mixing structure of ejector pipe a2, no
It repeats again.Wherein, secondary mixing ejector pipe a2 includes injection entrance 21, eductor outlet 22, injection-crossing current connecting rod 23, crossing current
Straight tube 24 and crossing current Venturi tube 25；Venturi tube 25 of flowing over includes contraction type ejector pipe a251, contraction type ejector pipe b252, receives
Contracting formula ejector pipe c253 and contraction type ejector pipe d254.
Venturi tube 1 is horizontally arranged such as Fig. 1 and Fig. 2 as the preferred embodiment of the present invention, then by secondary mixing
Ejector pipe a2, secondary mixing ejector pipe b3, secondary mixing ejector pipe c4 and secondary mixing ejector pipe d5 are tightly fixed to text respectively
On four perforations of 1 throat of venturi, the outer tube wall and perforation inner wall of four injection entrances are fitted close, each injection entrance
Straight tube mouth stretch out except 1 throat of Venturi tube for accessing jet media, to reach effect shown in Fig. 1, composition entirely may be used
Secondary mixed Venturi tube.Position of each secondary mixing ejector pipe in 1 throat of Venturi tube is as shown in Figure 3 and Figure 4, secondary
Mixing ejector pipe a2 and secondary mixing ejector pipe c4 is fixed on 1 throat of Venturi tube, correspondingly, secondary mixing along the vertical direction
Ejector pipe b3 and secondary mixing ejector pipe d5 is fixed on 1 throat of Venturi tube, and each secondary mixing ejector pipe in the horizontal direction
On crossing current Venturi tube axial line it is equal away from 1 throat's axle center wire spacing of Venturi tube.
In conjunction with Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, secondary mixing ejector pipe a2, secondary mixing ejector pipe b3, secondary mixing are drawn
It is identical with the secondary mixing course of work of ejector pipe d5 to penetrate pipe c4, as space is limited, is said by taking secondary mixing ejector pipe a2 as an example
The secondary mixed process of crossing current-jet stream in bright entire Venturi tube, the interior crossing current fluid of Venturi tube 1 is through left side divergent segment entrance stream
Low pressure is formed when to throat, Jetstream fluid is acted on by inside and outside differential pressure and being flowed into 1 throat of Venturi tube through injection entrance 21, and through drawing
Exit wound of bullet 22 flows out, and realizes the mixed once with crossing current fluid in Venturi tube 1.It flows over the part of 1 throat's leading portion of Venturi tube
Fluid flow through crossing current straight tube 24 after enter crossing current Venturi tube 25, and flow to crossing current 25 throat of Venturi tube when formed it is low
Pressure, with the mixed once liquid of each contraction type ejector pipe institute injection and crossing current liquid complete it is secondary mix, to realize entire text
The secondary mixing of crossing current fluid and Jetstream fluid, keeps mixed effect more full and uniform in venturi.
As shown in Figure 1, Venturi tube 1 is a conventional circular section Venturi tube, opened up along circumferentially-spaced 90 ° of throat's outer wall
Obtained by four round perforations, position of opening is located at the quartering on throat's outer wall bus close to 1 divergent segment entrance of Venturi tube
At point.
Secondary mixing ejector pipe a2, secondary mixing ejector pipe b3, secondary mixing ejector pipe c4 and secondary mixing ejector pipe d5
Structure is identical.It mainly include that injection entrance 21, injection go out by taking secondary mixing ejector pipe a2 as an example such as Fig. 6,7,8 and 9
Mouth 22, injection-crossing current connecting rod 23, crossing current straight tube 24 and crossing current Venturi tube 25.Injection entrance 21 be straight round tube, end with
Eductor outlet 22 is connected, and eductor outlet 22 is quarter bend round tube, and injection-crossing current connecting rod 23 is solid round rod, eductor outlet 22
Lower end is connected by injection-crossing current connecting rod 23 with crossing current straight tube 24, and crossing current straight tube 24 is straight round tube, end and literary mound of flowing over
In pipe 25 be connected.The throat of crossing current Venturi tube 25 is connected to contraction type ejector pipe a251, contraction type ejector pipe b252, contraction type and draws
Penetrate pipe c253 and contraction type ejector pipe d254；Four contraction type injection tube structures are identical and circumferential etc. (90 °) of angular separation are distributed,
Part outside crossing current Venturi tube 25 is bucket-shaped, is cylindrical tube, each contraction type with the part that connects of crossing current Venturi tube 25
Ejector pipe is connected with crossing current 25 throat of Venturi tube.1 throat's perforation internal diameter of Venturi tube, 21 outer tube diameter of injection entrance,
22 outer tube diameter of eductor outlet, injection -23 outer diameter of crossing current connecting rod, crossing current 24 outer tube diameter of straight tube and crossing current 25 outer tube diameter of Venturi tube
It is all the same；Caliber in injection entrance 21, caliber in eductor outlet 22, caliber and crossing current 25 flaring of Venturi tube in crossing current straight tube 24
Section outlet inner headed face diameter is all the same.
For the industries such as emulsion preparation, agricultural fertilizer, fuel gas decoking, the mixing of Venturi transmission ejector interior fluid mediums
Effect will directly affect production and working efficiency, but conventional injection mixing, the undercompounding of fluid media (medium), uniformly.
And one kind of the present invention can secondary mixed Venturi tube, crossing current fluid and Jetstream fluid are by literary mound in Venturi tube 1
In effects mixed once is completed at throat, but mixed once region flow field turbulence intensity is smaller, crossing current and Jetstream fluid
It is not thoroughly mixed.After crossing current fluid is influenced by Venturi effect, part of fluid is flowing to crossing current 25 throat of Venturi tube
When form low pressure, with mixed once liquid on the outside of 25 throat of crossing current Venturi tube of each contraction type ejector pipe institute injection and crossing current liquid
Body completes secondary mixing, and the throat section for Venturi tube 25 of flowing over is smaller, and Mixed Zone turbulence intensity is larger in throat, outside throat
Each bucket shape contraction type ejector pipe plays the role of spoiler, increases External airflow field turbulence intensity, to realize entire Venturi tube
The secondary mixing of interior crossing current fluid and Jetstream fluid, improves mixed once effect, makes mixing for crossing current fluid and Jetstream fluid in pipe
Dark conjunction is more full and uniform.
In conclusion the present invention is in venturi throat by installing secondary mixing ejector pipe additional, in Jetstream fluid and cross
It flows fluid to complete to carry out secondary injection mixing on the basis of an injection mixing, achievees the purpose that improve mixed effect；Utilize two
Contraction type ejector pipe outside secondary mixing ejector pipe throat increases turbulence intensity in venturi throat, makes to flow over as spoiler
It is with jet mixing more full and uniform.
