Description
Technical field
The utility model is related to a kind of venturi mixer, and in particular to the literary mound of streamlined deflector is contained in a kind of throat
In blender.
Background technology
Venturi mixer is generally used for the injection of two kinds of fluids with mixing, and mainstream fluid sequentially passes through inflow segment, tapered
Section, throat's pipeline, divergent segment and outflow section, introduce throat's pipeline that fluid enters mainstream fluid via introducing pipeline.Main current flow
Body enters in throat's pipeline when flowing, and its flow velocity is very fast, pressure is relatively low, using being introduced into fluid and mainstream fluid in throat's pipeline
Pressure differential is introduced into fluid introducing, realizes the mixing of two kinds of different fluids.Venturi mixer be widely used in chemical industry, irrigate with
And in the industrial circle such as the energy.
There is mainstream fluid with introducing the problem of fluid mixes uneven in existing venturi mixer.In mainstream fluid stream
Go out on the outlet of section, the concentration for introducing the introducing fluid of the introduction point side of pipeline is higher, and the introducing fluid of opposite side
Concentration is relatively low.The reason for above-mentioned phenomenon occur is that the flow velocity for introducing fluid is relatively low, when throat's pipeline is introduced, in introducing
The flow behavior of reunion shape is presented in throat's pipeline near wall region of point side, does not fully carry out mass exchange with mainstream fluid.
Above-mentioned phenomenon flows through divergent segment after fluid-mixing and outflow Duan Shiwei is effectively improved, so as to finally cause the mixed of outflow
Collaborate body mixing uneven.
The content of the invention
To solve above-mentioned problems of the prior art, the purpose of this utility model is that providing a kind of throat contains stream
The venturi mixer of line style deflector, the initial stage that can be introduced in introducing fluid is to be prevented effectively from introducing fluid near wall area
There is the flow behavior of reunion shape in domain, strengthens the disturbance of throat region fluid, so as to lift the mixed effect of venturi mixer.
In order to achieve the above object, the technical scheme that the utility model is used is：
The venturi mixer of streamlined deflector is contained in a kind of throat, including inflow segment 1, converging transition 2, throat's pipeline 3,
Divergent segment 4, outflow section 5 and pipeline 6 is introduced, the introducing pipeline 6 is connected with throat pipeline 3, it is characterised in that：Also include stream
Line style deflector 7, the streamlined deflector 7 is that cross sectional shape is fairshaped column solid member, and the axial direction of throat's pipeline 3 is long
Degree is designated as L, and the axis of the introducing pipeline 6 is located at away from the outlet L/4 of converging transition 2, the streamlined stagger arrangement cloth of deflector 7
It is placed in the interior zone of throat's pipeline 3 introduced between the axis of pipeline 6 and the entrance section of divergent segment 4, the two ends of streamlined deflector 7
By the internal face for being fixedly welded on throat's pipeline 3.
Compared to the prior art, the utility model has advantages below：
1st, the venturi mixer of streamlined deflector is contained in a kind of throat that the utility model is provided, using introducing fluid
The streamlined deflector that throat's conduit region after introducing is staggered in arrangement, enhancing introduces the mass exchange of fluid and mainstream fluid.
Throat's pipeline is rate of flow of fluid most fast region, is also to introduce the region that fluid is introduced, streamlined water conservancy diversion is set in this region
Plate, the initial stage that can be introduced in introducing fluid is to be prevented effectively from introducing fluid to occur the flowing spy of reunion shape near wall region
Property.
2nd, the streamlined deflector that the utility model is used is compared to cylindrical spoiler, and its flow resistance is relatively low, so that
Reduce the power of fluid delivery pump.
3rd, the utility model is introducing the setting streamline of the fluid mixing region between conduit axis and divergent segment entrance section
Type deflector, and be introduced into the axis of pipeline and be arranged at away from the L/4 of converging transition outlet, expand streamlined deflector and exist
The zone of action in throat's pipeline.
Brief description of the drawings
Fig. 1 is the sectional view for the venturi mixer that streamlined deflector is contained in a kind of throat of the utility model.
Fig. 2 is the top view for the venturi mixer that streamlined deflector is contained in a kind of throat of the utility model.
Fig. 3 is the left view for the venturi mixer that streamlined deflector is contained in a kind of throat of the utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The venturi mixer of streamlined deflector is contained in a kind of throat of the utility model, including inflow segment 1, converging transition 2,
Throat's pipeline 3, divergent segment 4, outflow section 5, and pipeline 6 is introduced, the introducing pipeline 6 is connected with throat pipeline 3, in addition to is flowed
Line style deflector 7.
As shown in Figure 1, Figure 2 and Figure 3, the streamlined deflector 7 is that cross sectional shape is fairshaped column solid member, wrong
Row are arranged in the interior zone of throat's pipeline 3 between the axis and the entrance section of divergent segment 4 for introducing pipeline 6, streamlined deflector 7
Two ends by being fixedly welded on the internal face of throat's pipeline 3.The rate of flow of fluid of throat's pipeline 3 is most fast, while being also to introduce fluid
The position being initially charged into.Streamlined deflector 7 is set in this region, can introduce fluid introduce earlier damage its in larynx
The reunion shape fluid micellar that the near wall region of portion's pipeline 3 occurs, strengthens the disturbance of fluid, it is to avoid mixed fluid is in throat
Occurs serious mixing in the region of pipeline 3 uneven.Afterwards, mixed mainstream fluid is with introducing fluid by divergent segment 4 and stream
Go out section 5 and carry out further mass exchange, finally obtain more uniform fluid-mixing in the outlet of outflow section 5.This practicality is new
Type uses streamlined deflector 7, and compared to cylindrical spoiler, its flow resistance is relatively low, so as to reduce fluid delivery pump
Power.Meanwhile, streamlined deflector 7 is staggered in arrangement, and enhances the disturbance effect of fluid.
As shown in figure 1, the axial length of throat's pipeline 3 is designated as L, the axis for introducing pipeline 6 is located at away from the outlet section of converging transition 2
At the L/4 of face.Mainstream fluid is when entering throat's pipeline 3, and because cross section of fluid channel product diminishes, flow velocity is accelerated, according to Bernoulli's theorem,
Now the pressure of mainstream fluid is relatively low, and injection is carried out using mainstream fluid and the pressure differential for introducing fluid.Experiment discovery, main current flow
The pressure of body has kept stable after throat's pipeline 3 is entered after of short duration adjustment, and in other words, this practicality is introduced into a position
Put move forward to the axis for introducing pipeline 6 be located at away from the outlet L/4 of converging transition 2 to the injection performance of venturi mixer script
Influence is little.But, above-mentioned arrangement expands the zone of action of the streamlined deflector 7 in throat's pipeline, enhances stream
The facilitation effect that line style deflector 7 is mixed to fluid.
