Specific implementation mode
The utility model is further described below in conjunction with attached drawing.
As shown in Figure 1, 2, the utility model specific implementation includes sub-inlet pipeline 3, main inlet pipe 4 and outlet conduit 1,
It is characterized in that：Including the knot type mixing duct 2 being connected between sub-inlet pipeline 3, main inlet pipe 4 and outlet conduit 1,
The knot type mixing duct 2 is arranged to the knot shape of three leaf junction type of the right hand or 8 word junction types.Sub-inlet pipeline 3, master
Inlet duct 4 and knot type mixing duct 2 are connected directly successively with 1 three parts of outlet conduit, constitute the master of knot type mixer
Body.
Main inlet pipe 4 and sub-inlet pipeline 3 are commonly connected to the arrival end of knot type mixing duct 2, knot type mixing
The outlet end of pipeline 2 and outlet conduit 1 connect.
The interface of outlet conduit 1, main inlet pipe 4 and sub-inlet pipeline 3 is respectively provided with mounting base 5, in each mounting base 5
It is respectively provided with there are four bolt mounting holes, mounting base 5 passes through four bolt mounting holes and external input channel and output channel phase
Even.
The centerline collineation of outlet conduit 1 and main inlet pipe 4, main inlet pipe 4 is with sub-inlet pipeline 3 at an angle of 90 degrees
It is arranged vertically.Sub-inlet pipeline 3 and main inlet pipe 4 and 2 junction of knot type mixing duct, knot type mixing duct 2 and go out
The pipeline transient mode of 1 junction of mouth pipeline is continual curvature transition.
The implementation process of the utility model is：
Consider to be under normal circumstances that The faster the better to the requirement of mixing velocity, gives tacit consent to the liquid flow patterns in mixing duct
For turbulent flow.It is time inlet duct that main inlet pipe 4, which is used as main inlet pipe, sub-inlet pipeline 3, and two inlet ducts can be passed through not
Same liquid, the liquid stream Reynolds number after crossing rise, and flowing velocity is accelerated.
Due to the knot shape of mixing duct, liquid back and forth folds in the duct, and the speed field of line of flowing tends to be chaotic, more
Easily enter turbulence state.Enter knot type mixing duct after, the rising due to Lei Luo numbers and pipeline configuration, internal fluid it is disorderly
Stream aggravates, and the degree aggravation mutually blended between liquid, mixed effect rises.If the degree of turbulent flow is higher, in liquid flowing also
Some tiny vortexs are will produce, thus there is further enhancing again to mixed effect.
The utility model is not suitable for flowing the mixing of slow liquid, and Reynolds number of the liquid in inlet at least should be
2000 or more.
The embodiments of the present invention are as follows：
Mixer structure specifically uses the mixer of 8 word junction type shown in FIG. 1.
Emulation experiment situation is that principal inlet passage is passed through water, and sub-inlet channel is passed through alcohol, and the speed being passed through is 1m/s,
The total length of emulation channel is taken as 280mm, internal diameter 12mm.Experiment is distributed shape eventually by the alcohol concentration of examination mixer outlet
Condition judges the mixed effect of mixer, and closer to 0.5, mixed effect is better.
Experimental result is：Fig. 5 is that a kind of passive mixing device of knot type exports alcohol concentration distribution map, it can be seen that wine
Concentration distribution situation of the essence on outlet.At the worst place of mixed effect, a concentration of the 0.495 of alcohol, and outlet
For the uniformity of alcohol concentration by being calculated as 98%, this illustrates that two kinds of liquid mixing of mixing is more abundant.Fig. 6 is a kind of
The passive mixing device inner section polar plot of knot type, each arrow indicates the directional velocity of liquid herein, it is possible thereby to sentence
The generation of disconnected liquid internal eddy flow.
Comparative example is as follows：
Comparative example mixer structure specifically uses common S types mixer shown in Fig. 3, passes through S-shaped between entrance and exit
Pipeline connects, and entrance and exit is connected to the both ends of S-shaped pipeline.
Experimental result is：The mixer outlet alcohol concentration distribution map of common S types is as shown in figure 4, mix the wine at worst place
Essence a concentration of 0.45, differs larger with 0.5, and the uniformity of outlet alcohol concentration is 82%, can be sentenced by comparison
The mixer of disconnected 8 fonts effectively improves mixed effect.
Above-mentioned specific implementation mode is used for illustrating the utility model, rather than limits the utility model,
In the spirit and scope of the claims of the utility model, to any modifications and changes that the utility model is made, all fall
Enter the scope of protection of the utility model.
