Specific embodiment
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1 and Figure 2, the invention proposes it is a kind of force strained polymer tubular type dissolver, including it is multiple with
The dissolution unit 1 of the removable coaxial parallel connection of mode, each dissolution unit 1 include that hydrostatic column 15, transmission shaft 8 and stretching are ground
Grinding machine structure 9.Wherein, the middle part that hydrostatic column 15 is arranged in grinding mechanism 9 is stretched, by the inner space of hydrostatic column 15 point
It is divided into first chamber 6 and second chamber 7.Be provided on the side wall of hydrostatic column 15 import 4 and outlet 5, wherein import 4 with
First chamber 6 is connected to, and outlet 5 is connected to second chamber 7.Transmission shaft 8 is arranged on the axis of hydrostatic column 15, stretches grinding
Mechanism 9 is mounted on transmission shaft 8.When multiple dissolution units 1 are coaxial in parallel, transmission shaft 8 can drive each dissolution unit 1 simultaneously
Stretching grinding mechanism 9 operate synchronously.Tubular type dissolver of the present invention can drive mother liquor demand according to platform polymerization object
And stage+module condition, neatly the quantity of Selective dissolution unit 1, can also select vertical or sleeping according to actual service conditions
Formula installation, can not only substantially reduce the occupied area of whole device, also have discharge capacity flexibly adjustable advantage, improve in sea
The use scope of upper polymer flooding compounding system.
Further, stretching grinding mechanism 9 is used is made of the first rotor 10, turn 11, the second rotor 12
Fixed-dynamic-stator and rotor sructure.
Further, further include inlet manifold 2 and liquid outlet manifold 3, inlet manifold 2 respectively with each dissolution unit 1
Import 4 connect, liquid outlet manifold 3 respectively with it is each dissolution unit 1 outlet 5 connect.To guarantee that polymer solution can be smooth
Into each import 4, at each import 4 small-displacement screw pump is installed respectively, feeding power is provided.Meanwhile in liquid outlet manifold 3
Converge setting huge discharge screw pump on general pipeline, polymer solution is delivered in curing tank and does further curing.
Further, cleaner 14 is provided in first chamber 6, and cleaner 14 is mounted on transmission shaft 8.It is preferred that
, cleaner 14 is cross shape impeller, which has 4 flabellums, and the inclination angle of flabellum is 60 °, width 4cm.
For Study Polymer Melts mixed dissolution effect, the design shown in carries out the modeling processing of single container tank, such as Fig. 3
Institute's representation model, the inlet flow rate by design are 3.333kg/s (60m3/ h), movable tooth wheel speed is 24rad/s, is counted by simulation
Calculation is shown in Table 1, it can be seen that with the increase of Polymer Solution Viscosity, is gradually decreased by the flow of the device, in solution viscosity
It is that can guarantee that the inflow-rate of water turbine of single model is more than 12.5m when lower than 20mPas3/ h, that is to say, that 5 concatenated containers are
It can satisfy 60m3/h；It is to show the state that one is swollen (to polymerize when hydrophobic associated polymer powder and water initial contact
Object solution viscosity will not rapid increase), this process generally requires 8min or so；It therefore, is that can satisfy after which reduces
Inflow-rate of water turbine carries out forcing strained polymer swellable particles.
The mistake stream calculation of independent model under the conditions of the different viscositys of table 1
| Viscosity mPas | Flow kg/s |
| 1(water) | 12.7164 |
| 5 | 8.2764 |
| 10 | 5.9180 |
| 15 | 4.4000 |
| 20 | 3.4125 |
As can be seen from Figure 3 the entire bipolar rotation bring eddy flow for stretching turn 11 in grinding system promotes fluid
Overcurrent main force channel be in the outside of model, and it can be seen that (revolving speed 24rad/s) from Fig. 4 simulation cleaner flowing, cleaning
Device 14 can form stronger flow regime in the first rotor 10, can scrape polymer swellable particles, the eddy flow of formation makes
Entire second chamber 7 is in a rotation status, and fluid is forced to form a biggish flow regime in outside of containers, promotes whole
The overcurrent of a fluid.
The various embodiments described above are merely to illustrate the present invention, and wherein the implementation steps etc. of method may be changed,
All equivalents and improvement carried out based on the technical solution of the present invention, should not exclude in protection scope of the present invention
Except.
