Brief description
Fig. 1 is the sectional view of the utility model static mixer.
Fig. 2 is the top view of the utility model static mixer.
Reference is as follows: Venturi tube the 1st, throat the 2nd, second liquid entrance the 3rd, second liquid distribution rings the 4th, second liquid divides
The 5th, cloth hole is fixed axle the 6th, impeller inducer the 7th, guide vane and the 8th, is reflected pallet the 9th, deflector the 10th, connecting plate 11.
Detailed description of the invention
Presently in connection with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, 2, new type static mixer of the present utility model includes Venturi tube the 1st, second liquid entrance the 3rd,
The 4th, two liquid distribution rings are fixed axle the 6th, impeller inducer and the 7th, are reflected pallet the 9th, deflector 10 and connecting plate 11.
First liquid (i.e. main flow liquid) vertically flows into blender by Venturi tube 1, is provided with throat in the middle part of Venturi tube 1
2, first liquid flows into from Venturi tube 1 upper end open, through throat 2, then flows out from lower ending opening.Second liquid entrance 3 with
Second liquid distribution rings 4 vertical connection is arranged, and second liquid vertically flows into second liquid distribution rings 4 from second liquid entrance 3,
Second liquid distribution rings 4 closely surrounds throat 2 and arranges.Throat 2 is provided with plural second liquid distribution hole 5, second liquid
Distribution hole 5 connects second liquid distribution rings 4 and throat 2 so that the second liquid in second liquid distribution rings 4 passes through second liquid
Distribution hole 5 mixes in throat 2 with first liquid.
Being provided with fixing axle 6 below Venturi tube 1, fixing axle 6 faces the lower part outlet of Venturi tube 1, and fixing axle 6 is vertical
It is arranged on the reflection pallet 9 of circular arc bowl-type, as it is shown in figure 1, Venturi tube the 1st, fixing axle 6 and reflection pallet 9 are all coaxially disposed.
Wherein, fixing axle 6 is from top to bottom installed in series and has more than one impeller inducer 7, and each impeller inducer 7 is provided with two or more
Guide vane 8, the guide vane 8 of two impeller inducers 7 of arbitrary neighborhood possesses contrary direction of twist.On reflection pallet 9
Being provided with plural deflector 10, deflector 10 is vertically mounted on reflection pallet 9, forms certain bending, its bending
Direction is contrary with the direction of twist of the guide vane 8 of hithermost impeller inducer 7.
It is also uniformly connected with multiple connecting plate 11, traditional civilian mound between second liquid distribution rings 4 and reflection pallet 9
In in static mixer connecting plate be all radially to install, as in figure 2 it is shown, connecting plate 11 and reflection pallet 9 in the utility model
Radius is the angle of 0～90 °, and connecting plate 11 is radially formed certain deflection, the bending side of its yawing moment and deflector 10
To on the contrary.
In mixed process, first liquid flows through the throat 2 of Venturi tube 1, and circulation area reduces, and flow velocity increases, pressure
Reduce.Second liquid vertically flows into second liquid distribution rings 4 from second liquid entrance 3, by second liquid distribution hole 5 and first
Liquid mixes in throat 2；Mixing liquid produces with the guide vane 8 of the impeller inducer 7 being arranged on fixing axle 6 downwards and clashes into,
Owing to the guide vane 8 on two impeller inducers 7 of arbitrary neighborhood possesses contrary direction of twist, the flow direction of mixing liquid can not
Change disconnectedly and produce disturbance, completing second time and mix；Mixing liquid continues to produce with reflection pallet 9 downwards to clash into, because of
It is mounted with the vertical baffle contrary with the direction of twist of the guide vane 8 on the impeller inducer 7 being close on reflection pallet 9
10, due to the change again in direction, level of disruption aggravates, and makes third time mixed effect more preferable；Owing to reflecting the circular arc of pallet 9
Bowl-type designs, and mixed liquor is rotated upwards by reflecting pallet 9, produces with the connecting plate 11 of deflection and clashes into, inclined due to connecting plate 11
Turning direction contrary with the bending direction of deflector 10, direction changes again, produces violent disturbance, completes the 4th time and mixes
Close.Whole process is very of short duration, and mixing liquid changes continuously, rapidly and flows to so that the mixing velocity of liquid faster, effect more
Good.
The utility model can be used for the production of caprolactam, in the production process of caprolactam, cyclohexanone oxime be fuming
Sulfuric acid carries out Beckmann rearrangement at 120 DEG C, and this reaction is quick a, strong exothermal reaction, the reaction after rearrangement reaction
Circulation fluid must be sufficiently mixed with cyclohexanone oxime within the time the shortest, and mixed effect difference can cause hot-spot, and side reaction adds
Play, will directly affect the quality of rearrangement reaction.
When using new type static mixer of the present utility model, first liquid is reaction cycle liquid, and second liquid is hexamethylene
Ketoxime, reaction cycle liquid is respectively 200m with the flow of cyclohexanone oxime3/ h and 8m3/h；The throat 2 of Venturi tube 1 is a diameter of
60mm, a diameter of 3mm of second liquid distribution hole 5, hole count is 30, fixing axle is provided with 3 impeller inducers, each water conservancy diversion leaf
Being provided with 5 guide vanes on wheel, reflection pallet 9 being mounted with 5 deflectors 10, the height of deflector 10 is 50mm, connects
Plate 11 quantity is five pieces, and connecting plate 11 is 45 ° with the angle of reflection pallet 9 radius.
Reaction cycle liquid and cyclohexanone oxime are after throat 2 carries out mixing for the first time, downwards and the guide vane of impeller inducer 7
8 clash into, and complete second time and mix；Continue to clash into reflection pallet 9 downwards, complete third time and mix；Finally and even
Fishplate bar 11 clashes into, and completes the 4th mixing.
The quality rearrangement product indexing lipid amount of rearrangement reaction is weighed, and indexing fat titration value is to weigh indexing lipid amount
Simply, the index of easily measurement.Titration value is the KM by 0.1mol/LnO4Indexing fat is titrated by solution, and normal titration value exists
About 1.7ml/mg, in titration value bigger explanation indexing fat, reducing impurity content is higher, and side reaction during rearrangement reaction is got over
Many.
Use this new type static mixer and above setup parameter to be prepared, after stable process conditions, record rearrangement product
Indexing fat titration value is dropped to 0.8～1.0ml/mg, follow-up caprolactam refining process gained by original about 1.7ml/mg
Impurity greatly reduces, and caprolactam per ton consumes cyclohexanone oxime and is decreased obviously.
Below being only preferred embodiment of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonging under the utility model thinking belong to protection domain of the present utility model.It is right to it should be pointed out that,
For those skilled in the art, some improvements and modifications under the premise of without departing from the utility model principle,
Should be regarded as protection domain of the present utility model.
