Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 2, main flow conduit 1,2, two venturi mixers 3 of shunt conduit, venturi mixer introducing pipe 4,
Bus dump 5 and a Venturi tube 6 have collectively constituted a kind of venturi mixing arrangement repeatedly mixed.What this was repeatedly mixed
Venturi mixing arrangement wall thickness is 10mm, and in the axial direction, main pipeline 1 is 200mm long, internal diameter 80mm, shunt conduit 2 and confluence
The length of pipeline 5 is 140mm, which is 1660mm.
As shown in Figure 1, introducing pipe 4 is that a main introducing pipe a splits into two internal diameters and the identical secondary introducing of shape
Pipe b, main introducing pipe a and the secondary pipe b that introduces are circular pipe, and main introducing pipe a internal diameter 40mm, outer diameter 50mm, secondary introduce pipe b
Internal diameter 30mm, outer diameter 40mm, in the axial direction, introducing 4 total length of pipe are 200mm.
As shown in Figures 2 and 3, shunt conduit 2 is identical with the structure of bus dump 5, due to 3 He of venturi mixer
The size of Venturi tube 6 is slightly different, therefore the internal diameter and outer diameter of shunt conduit 2 and bus dump 5 are also slightly different, isocon
The arrival end c internal diameter 80mm in road 2, two outlet end d internal diameters of outer diameter 100mm, shunt conduit 2 are 84mm, and outer diameter is
104mm, the two entrances end e internal diameter of bus dump 5 are 88mm, and outer diameter is 108mm, the outlet end f internal diameter of bus dump 5
84mm, outer diameter 104mm.
As shown in Figure 1, Figure 2 and Figure 3, the identical venturi mixer 3 of two structure snd size is put down in the axial direction
Capable and placed side by side, the axial line distance of two venturi mixers 3 is 124mm, as shown in figure 4, in the axial direction, venturi is mixed
3 entrance segment length 140mm of clutch, internal diameter 84mm, tapered segment length 90mm, the long 100mm of throat, internal diameter 52mm, flaring segment length 110mm,
Export segment length 150mm, internal diameter 88mm, venturi mixer overall length 590mm.
As shown in Figure 1, Figure 2 and Figure 3, the axis of Venturi tube 6 and the axis of entire venturi mixing arrangement are completely coincident,
Fluid-mixing mixes again in the throat of Venturi tube 6, and flows out entire venturi mixing dress in the exit of Venturi tube 6
It sets, as shown in figure 4, in the axial direction, the entrance segment length 140mm of Venturi tube 6, internal diameter 84mm, tapered segment length 90mm, throat head
100mm, internal diameter 52mm, flaring segment length 110mm export segment length 150mm, internal diameter 88mm, and the length of entire Venturi tube 6 is
590mm。
After mainstream fluid is from 1 entrance of main flow conduit into the device, by shunt conduit 2, two structure snd size are flowed into
Identical venturi mixer 3 introduces after pipe 4 shunts and is respectively connected to two 3 throats of venturi mixer, introduces fluid
It realizes in throat and the mainstream fluid of the two venturi mixers 3 and mixes for the first time, then, fluid-mixing is from two venturi
The outlet of mixer 3 outflow is exported by bus dump 5 after the confluence of bus dump 5, second of realization mix and flows into Venturi tube
6, due to the effect of Venturi effect, fluid-mixing is turbulent again in Venturi tube 6, mixes, finally going out in Venturi tube 6
It is flowed out at mouthful.
Since the entrance cross-sectional area of Venturi tube 6 is smaller than the sum of the discharge area of two venturi mixers 3, because
This, in the inlet of Venturi tube 6, the two fluids that is flowed out from two venturi mixers 3 can because sectional area becomes smaller and
Flow velocity increases, so that turbulent flow of the fluid in Venturi tube 6 is more violent, fluid is more fully mixed.
Since co-blended is two strands for the first time three times to fluid-mixing in this venturi mixing arrangement repeatedly mixed
Mainstream fluid in venturi mixer 3 and introduces the introducing fluid mixing that pipe 4 introduces respectively, is two strands for the second time in text
Mixed in mixer 3 in mound, but mix not fully fluid-mixing, in bus dump 5 by confluence, hit, then
Secondary mixing is that the fluid-mixing after confluence mixes again in Venturi tube 6 for the last time, and it is equal to be finally reached two kinds of fluid mixing
Even purpose.Simultaneously as the device increases much compared to length for common venturi mixer, therefore it is more advantageous to
Fluid is sufficiently mixed, to reach production or experiment purpose.
It is the specific design scheme for the venturi mixing arrangement that the utility model one kind repeatedly mixes above.
