Description

Technical Field

[0001] This invention relates to the field of polymer rapid stirring, stretching, dispersion and dissolution technology, and in particular to a rapid dissolution integrated device for polymer stirring, stretching and dispersion. Background Technology

[0002] Traditional offshore platform polymer dispensing systems employ a skid-mounted design, comprising four systems: a dry powder conveying system, a dispersion system, a curing system, and an injection system. Among these, components such as the water-powder mixer, dissolving tank, agitator, and curing tank occupy a large area and require substantial lifting capabilities. Therefore, the polymer dispensing unit must be compact and lightweight.

[0003] Furthermore, due to the difficulty in dissolving polymers prepared from wastewater, traditional mixing methods result in slow dissolution rates when using water-powder mixtures. Given the scarcity of freshwater resources at sea, the use of treated wastewater as the polymer preparation method leads to longer dissolution times, necessitating additional curing tanks to ensure sufficient time for dissolution. This further restricts space on offshore platforms. Only by shortening the dissolution time of polymers prepared from wastewater can this problem be fundamentally solved.

[0004] The unique characteristics of offshore oil fields require polymer dispensing units to possess features such as rapid dissolution, large dispensing volume, small size and footprint, light load, and high viscosity retention. Simply replicating existing polymer dispensing equipment used in onshore oil fields is clearly insufficient. Therefore, existing technologies have adopted continuous mixing and rapid dissolution integrated units to solve the polymer dispensing challenges on offshore platforms.

[0005] The continuous mixing and dispersing rapid dissolving integrated device is an enhanced rapid dissolving equipment. Its core components include a motor, an agitator, a shear head consisting of a stator and rotor, and a packed bed rotor. Water and powder are mixed by opposing airflows and simultaneously stirred by the agitator. The shear head, composed of the stator and rotor, features a narrow shear gap and a high linear velocity at the rotor tip. Driven by the motor, a large velocity gradient and strong kinetic energy are generated, subjecting the material to intense shearing, compression, friction, impact, and grinding within the gap between the stator and rotor. Under the influence of the airflow, the material rapidly enters the packed bed rotor for further dissolution and is finally discharged through the outlet. However, the continuous mixing and dispersing rapid dissolving integrated device still has the following shortcomings; (1) Stirring dissolving equipment usually requires a large installation space: the stirring container itself has a certain volume, and in order to ensure the stirring effect, a certain amount of operating space and installation position of auxiliary equipment (such as motors, reducers, etc.) need to be reserved around it. Although jet mixing dissolving equipment is relatively compact, it also requires the installation space of supporting high-pressure pumps, pipelines and spraying devices. In the case of relatively scarce land resources, this is a clear disadvantage.

[0006] (2) The dissolution speed of the stirring type dissolution equipment mainly depends on the rotating speed, shape of the stirring paddle and stirring time: for some high viscosity polymers or polymer particles with large particle size, the traditional equipment can not provide sufficient shear force and mixing effect, resulting in incomplete dissolution or too long dissolution time.

[0007] (3) Some high molecular polymers need to shear the molecular chain during stirring dissolution, and at the same time need to be dispersed into a uniform solution, while the traditional equipment can only complete the stirring and shearing process, and cannot generate the required polymer solution at one time.

[0008] Therefore, there is an urgent need for a polymer stirring, stretching and dispersing rapid dissolving integrated device. SUMMARY

[0016] The beneficial effects are: The liquid enters the rotating stirring unit through the liquid inlet distribution baffle, and is sprayed into the stirring area through the multiple round holes of the liquid inlet distribution baffle, which is similar to the effect of a shower head.

[0017] The material needs to be transported by a certain power, so a fan with a certain power is installed behind the material port, and when the material accumulates in the material hopper, the fan is started to blow the material into the interior of the equipment, and in order to make the material enter the stirring bin uniformly dispersed and mixed with water without agglomeration into blocks, a Venturi jet device is arranged at the material inlet.

[0018] The liquid inlet distribution baffle of the stirring unit can uniformly disperse water, and the liquid outlet distribution baffle has the function of accumulating liquid, so that the stirring is more efficient.

[0019] The stretching and shearing unit mainly relies on the relative movement between the rotor and the stator to generate high shear force. When the rotor rotates at high speed, it drives the surrounding material to move together, while the stator remains stationary. The material is strongly squeezed, stretched and sheared in the narrow gap between the rotor and the stator. This shear force can break larger material particles into smaller particles, while different materials of different properties are fully contacted and uniformly mixed, which can realize uniform mixing of different materials in a short time, greatly improving the production efficiency. Meet the production demand of high product quality requirement. The product flow after shearing and stretching flows to the lowermost unit.

[0020] The porous filler in the packed bed rotor of the strong dispersion unit is provided with a plurality of holes, and when it is running, the polymer swelling-dissolving heterogeneous system is introduced into the filler area rotating at high speed. Due to the strong centrifugal force (usually tens to hundreds of times of gravity) generated by rotation, the polymer swelling-dissolving heterogeneous system is pulled into an extremely thin liquid film, liquid filament or even liquid droplet on the surface of the filler. The existence of this centrifugal field greatly strengthens the uniform dispersion process, which can significantly improve the efficiency under the same operating conditions.

[0021] Compared with traditional dispersion equipment (such as packed column, plate column, etc.), the present application can significantly improve the efficiency under the same operating conditions, and finally flow out the polymer solution with uniform viscosity from the liquid outlet. The present application has comprehensive functions, occupies small space, and is easy to install. Through the combined action of rotating stirring, shearing and stretching and uniform dispersion, the polymer is quickly dissolved, and the dissolution efficiency is improved.

[0022] The present application can completely complete the process of polymer stirring, shearing and dispersion, has simple structure and installation, can more efficiently complete the rapid dissolution of polymer, and can be more suitable for offshore platform oil exploitation, and solve the problems of large space required by existing devices and dispersed functions.

[0030] The entire technical process is described in detail below with a polymer stirring stretch dispersion's instant integrated device as an example.

[0031] Figure 1 And Figure 2As shown, the present application provides a polymer stirring stretching dispersion instant integrated device, which comprises a shell 4, a stirring unit 1, a stretching shear unit 2, a strong dispersion unit 3, a motor 5 and a feeding unit, the shell 4 is provided with a stirring bin and a stretching shear dispersion bin in communication from top to bottom, the stirring bin is provided with the stirring unit 1, the motor 5 is arranged at the top of the shell 4 and connected with the top of the stirring unit 1, the stretching shear dispersion bin is sequentially provided with the stretching shear unit 2 and the strong dispersion unit 3 from top to bottom, one side wall of the stirring bin is provided with a liquid port 4-1, the other side wall of the stirring bin is provided with the feeding unit, the upper end of the stretching shear dispersion bin is provided with a secondary water inlet 4-2, and the lower end of the stretching shear dispersion bin is provided with a liquid outlet 4-3.

[0032] The secondary water inlet 4-2 can be provided with a standard flange interface and a flange cover with a matching size as an opening and closing execution component, the contact surface of the flange cover and the flange interface is embedded with a sealing ring resistant to medium corrosion, so that the secondary water inlet 4-2 can be selected to open and close according to the specific type of polymer, and when secondary water is needed to increase the instant speed during the stretching and shearing process, a certain flow of water can be added for liquid supplement.

[0033] The stirring bin is provided with a first fixed ring 4-7 and a second fixed ring 4-8 from top to bottom, the stretching shear dispersion bin is sequentially provided with a third fixed ring 4-9, a fourth fixed ring 4-4 and a fifth fixed ring 4-11 from top to bottom, the stirring unit 1 is fixed in the stirring bin through the first fixed ring 4-7 and the second fixed ring 4-8, the stretching shear unit 2 is fixed in the stretching shear dispersion bin through the third fixed ring 4-9, and the strong dispersion unit 3 is fixed in the stretching shear dispersion bin through the fourth fixed ring 4-4 and the fifth fixed ring 4-11.

[0034] The feeding unit comprises a material hopper 4-4, a Venturi jet 4-6, a power delivery inlet 4-5 of a fan and the fan 6, the material hopper 4-4 is connected with the shell 4 through the Venturi jet 4-6, and the air inlet of the Venturi jet 4-6 is connected with the fan 6 through the power delivery inlet 4-5 of the fan.

[0035] When the device is started, the liquid enters the device through the liquid port 4-1, is evenly dispersed and sprayed into the stirring unit 1 through the liquid inlet shunt partition plate 1-1, at the same time, the polymer solid particles are stored in the material hopper 4-4, and the fan 6 located behind the material port is operated to blow the polymer solid particles into the Venturi jet 4-6 when the device is started.

[0036] The polymer particles with certain pressure enter the converging section of the Venturi injector 4-6, the pipe diameter of the converging section gradually decreases, and the flow rate of the material gradually increases. At the same time, the increase of the material speed will cause the pressure to decrease. After the material accelerates through the converging section and enters the throat section, the speed reaches the highest and the pressure drops to the lowest. The pressure at the throat is lower than the ambient pressure, so a negative pressure area is formed around the throat. Due to the negative pressure at the throat, the material particles are sucked into the Venturi injector 4-6 and enter the throat. The working fluid and the sucked fluid are fully contacted and mixed in the throat. Under the action of high-speed flow and turbulence, uniform mixing can be quickly realized.

[0037] As shown in Figure 2 The stirring unit 1 includes a liquid inlet flow separation baffle 1-1, a stirring screw shaft 1-2, a liquid outlet flow separation baffle 1-3, a plurality of first screws 1-4 and a plurality of first nuts 1-5. The upper part of the stirring screw shaft 1-2 is connected with the motor 5 through the liquid inlet flow separation baffle 1-1, and the stirring screw shaft 1-2 is provided with spiral stirring blades 1-6. The lower part of the stirring screw shaft 1-2 passes through the liquid outlet flow separation baffle 1-3. The liquid inlet flow separation baffle 1-1 is fixed with the first fixed ring 4-7 through the first screws 1-4 and the first nuts 1-5. The liquid outlet flow separation baffle 1-3 is fixed with the second fixed ring 4-8 through the first screws 1-4 and the first nuts 1-5. The liquid inlet flow separation baffle 1-1 and the liquid outlet flow separation baffle 1-3 are provided with a plurality of liquid outlet holes.

[0038] When the polymer solid particles are ejected out of the Venturi injector 4-6 and contacted with water and fully mixed by the high-speed series stirring screw device, the rotating power is provided by the motor 5. At this time, the polymer particles will swell to form a mixture of polymer large particles and water, which enters the stretching and shearing unit 2 through the liquid outlet holes of the liquid outlet flow separation baffle 1-3. The liquid outlet flow separation baffle 1-3 mainly plays a role of uniformly dispersing the fluid flowing out. The wall surface coagulates into blocks and falls into or flows into a direction, which causes the next unit to be unable to fully play a role. At the same time, the liquid outlet flow separation baffle 1-3 can play a role of accumulating liquid, so that the stirring screw shaft 1-2 can stir in the liquid accumulated to a certain height, which can fully mix and make the stirring more efficient.

[0039] As shown in Figure 3As shown, the tensile shear unit 2 comprises a first coaxial transmission 2-1, a first connecting shaft, a shear stator 2-2, a shear rotor 2-3, a plurality of second screws 2-4 and a plurality of second nuts 2-5, the shear stator 2-2 and the shear rotor 2-3 are sequentially arranged on the first connecting shaft from top to bottom, the first connecting shaft is connected with the stirring screw shaft 1-2 through the first coaxial transmission 2-1, a plurality of liquid inlet holes are arranged on the shear stator 2-2, the shear stator 2-2 and the shear rotor 2-3 are both double-tooth disc structures, the shear stator 2-2 is fixed with the third fixed ring 4-9 through the second screw 2-4 and the second nut 2-5, the tooth ring of the shear stator 2-2 and the tooth ring of the shear rotor 2-3 are mutually embedded, and a gap is left between the tooth disc of the shear stator 2-2 and the tooth disc of the shear rotor 2-3 to realize the high-speed rotation of the shear rotor 2-3 for tensile shear of the material.

[0040] The upper surface of the shear rotor 2-3 is designed as a guide slope surface with an inclination of 20°. The angle parameter is optimized to form a directional thrust force, which cooperates with the centrifugal force generated by high-speed rotation to efficiently guide the mixed liquid to flow from the cavity chamber to the shear gap, reducing liquid flow resistance; the inner surfaces of the shear stator 2-2 and the shear rotor 2-3 are precisely matched to form a uniform shear gap, ensuring that the fluid receives stable shear action when passing through. This structure design integrating the functions of guiding and shearing not only improves the efficiency of liquid flow introduction, but also guarantees the consistency of shear processing.

[0041] The shear stator 2-2 comprises a first tooth ring and a second tooth ring 2-7, the second tooth ring 2-7 is sleeved outside the first tooth ring, the shear rotor 2-3 comprises a third tooth ring 2-8 and a fourth tooth ring 2-9, the fourth tooth ring 2-9 is sleeved outside the third tooth ring 2-8, the second tooth ring 2-7 is embedded with the third tooth ring 2-8, and the second tooth ring 2-7 is embedded with the fourth tooth ring 2-9.

[0042] The space enclosed by the first tooth ring and the third tooth ring 2-8, and the space enclosed by the second tooth ring 2-7 and the fourth tooth ring 2-9 form a cavity chamber.

[0043] The first tooth ring, the second tooth ring 2-7, the third tooth ring 2-8 and the fourth tooth ring 2-9 each comprise a plurality of shear teeth 2-6 arranged adjacently, and a gap exists between adjacent shear teeth 2-6, the gap forms a narrow gap.

[0044] When the mixture mixed by the stirring unit 1 flows into the tensile shear unit 2, the fluid enters the cavity chamber through the liquid inlet hole above the shear stator 2-2, the fluid is guided to flow into the narrow gap, and the motor 5 drives the shear rotor 2-3 to rotate at high speed through the first coaxial transmission 2-1.

[0045] Due to the guide slope on the shearing rotor 2-3 and high-speed rotation, strong centrifugal force and suction force will be formed around it. Under the action of this suction force, the material located in the mixing container is sucked from all directions into the area where the shearing rotor 2-3 is located, providing a basis for subsequent shearing, mixing and other operations. After the material enters the narrow gap between the shearing stator 2-2 and the shearing rotor 2-3, due to the very small gap, the linear speed generated by the high-speed rotation of the shearing rotor 2-3 is extremely high, so that the material in this gap is subjected to strong shearing force. Just like cutting something with scissors, the material is continuously divided and refined under the action of this powerful shearing force, and the originally larger particles or lumps are gradually sheared into smaller particles, thereby increasing the dispersion degree and specific surface area of the material. At the same time, the rotation of the shearing rotor 2-3 also produces a squeezing effect on the material. Under the joint action of the shearing stator 2-2 and the shearing rotor 2-3, the material is confined in a narrow space and subjected to squeezing force from all directions. This squeezing force causes changes in the molecular structure of the material, further promoting the mixing and dispersion of the material, and also helps to break the agglomeration phenomenon that may exist in the material, making the material more uniformly distributed. And the surface of the shearing stator 2-2 and the shearing rotor 2-3 has a low roughness, generally controlled in the range of Ra1.6-Ra3.2um, when the material passes through the gap between the shearing stator 2-2 and the shearing rotor 2-3, it will rub against their surfaces. This friction can enhance the interaction between the materials and improve the mixing effect. When the shearing rotor 2-3 rotates at high speed, the material moves at high speed in the gap, and when the material collides with the shearing stator 2-2 or other obstacles, it will collide. This impact can produce strong impact force, further breaking and dispersing the particles of the material, and also promoting the mixing and reaction between the materials.

[0046] When the material passes through the stretching and shearing unit 2, the high molecular chains between the polymers are forced to stretch and shear, the swollen particles are crushed and expanded to form smaller swollen particles, and at the same time, the shearing rotor 2-3 rotates at high speed and flows into the lower flow distribution baffle 3-1 through the flow liquid cavity. Similarly, the upper baffle has the same effect of uniform liquid distribution and liquid accumulation. When the stretching area forms a certain amount of liquid, the swollen particle solution is repeatedly ground in the liquid accumulation by the centrifugal force of the shearing rotor 2-3 and the shearing stator 2-2, forming a polymer swelling-dissolution heterogeneous system flowing into the strong dispersion unit 3. After uniform distribution through the porous distribution baffle 3-1, it flows into the packed bed rotor 3-4 in the strong dispersion unit 3.

[0047] As Figure 4As shown, the strong dispersion unit 3 includes a flow distribution baffle 3-1, a second coaxial transmission 3-2, a second connecting shaft, a packed bed cover plate 3-3, a packed bed rotor 3-4, a bearing 3-5, a plurality of third screws 3-6, and a plurality of third nuts 3-7. The flow distribution baffle 3-1, the packed bed cover plate 3-3, and the packed bed rotor 3-4 are provided with a plurality of liquid holes. The packed bed rotor 3-4 is internally filled with porous filler. The flow distribution baffle 3-1, the packed bed cover plate 3-3, and the packed bed rotor 3-4 are arranged from top to bottom through the second connecting shaft. The second connecting shaft is connected with the first connecting shaft through the second coaxial transmission 3-2. The bottom of the second connecting shaft is fixed to the bottom of the shell 4 through the bearing 3-5 after passing through the packed bed rotor 3-4. The flow distribution baffle 3-1 is connected with the fourth fixed ring 4-4 through the third screw 3-6 and the third nut 3-7. The packed bed cover plate 3-3 is connected with the fifth fixed ring 4-11 through the third screw 3-6 and the third nut 3-7.

[0048] The three shafts are connected in sequence through the internal gear set / transmission unit of the coaxial transmission to form an integrated power transmission system. Unlike a single rigid series, the coaxial transmission has a multi-stage transmission function - by configuring gear sets with different transmission ratios, the stirring screw shaft, the shearing rotor shaft, and the packed bed rotor shaft can be driven by the same power source to output different rotational speeds.

[0049] After the polymer swelling-dissolution heterogeneous system enters the strong dispersion unit 3, the packed bed rotor 3-4 is internally filled with a large amount of porous filler. The porous filler has a high specific surface area and a good pore structure. The pore structure and shape of the porous filler affect the flow path and velocity distribution of the fluid. The presence of the porous filler provides a large contact area for the polymer swelling-dissolution heterogeneous system, enabling sufficient contact and thus improving mass transfer efficiency. When the gel flows in the pores of the porous filler, it is hindered and guided by the porous filler, making the fluid flow more complex and turbulent. This complex flow state is beneficial to increasing the contact time and frequency, further improving the mass transfer dispersion effect. When the rotor rotates, a strong centrifugal field is generated. Under the action of the centrifugal force, the gel is thrown to the outer edge of the filler. The presence of the centrifugal force causes the liquid to form an extremely thin liquid film, liquid filament, or even liquid droplet on the surface of the filler, increasing the liquid surface renewal rate and reducing the thickness of the liquid film, thereby greatly strengthening the mass transfer dispersion process.

[0050] Working process: After being uniformly dispersed by the liquid inlet flow distribution baffle 1-1, the water contacts the material and is mixed by the stirring screw shaft 1-2 at high speed to swell, and then enters the stretching and shearing unit 2 after being dispersed by the liquid outlet flow distribution baffle 1-3. The mixture flow is obtained after stirring in the stirring unit 1. The mixture flows into the stretch-shear unit 2, which generates high shear force by the relative movement between the shear rotor 2-3 and the shear stator 2-2. When the shear rotor 2-3 rotates at high speed, it drives the surrounding material to move together, while the shear stator 2-2 remains stationary. The material is strongly extruded, stretched and sheared in the narrow gap between the shear rotor 2-3 and the shear stator 2-2, so that the larger material particles are broken into smaller particles, and the materials of different properties are fully contacted and uniformly mixed. In addition, the secondary water inlet 4-2 can be used for secondary water addition according to the need. The polymer swells and dissolves in the heterogeneous system in the stretch-shear unit 2; The polymer swells and dissolves in the heterogeneous system in the stretch-shear unit 2;

[0051] Finally, it should be pointed out that the above examples are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions described in the foregoing examples can still be modified, or some technical features can be replaced by equivalent features.
