Description

Technical Field

[0001] This application relates to the field of fluid magnetization treatment technology, and in particular to a fluid magnetization treatment apparatus. Background Technology

[0002] Fluids are widely used in industrial production and daily life, especially in areas involving combustion or reaction, where their state has a crucial impact on efficiency and effectiveness. For example, in the use of fuel oil and combustion-supporting gases, their dispersibility and activity directly affect the completeness of combustion and energy utilization efficiency. With the development of technology, people are paying increasing attention to how to improve fluid performance to achieve more efficient and environmentally friendly production and lifestyles. Better fluid handling can promote combustion or reaction efficiency, reduce energy consumption and pollutant emissions, and is of great significance for promoting sustainable development in various industries.

[0003] In related technologies, invention patent application publication number CN87107681A discloses a fluid magnetization processor. In the fluid channel or storage chamber, a rotating body with a magnetic field generating component is provided, capable of free rotation, and this rotating body is connected to a rotation drive mechanism. By generating a rotating magnetic field in the fluid channel or storage chamber, the fluid is strongly magnetized, thereby effectively activating the fluid.

[0004] Chinese patent application CN107089711A discloses a fluid magnetization method and apparatus. The fluid magnetization apparatus includes an internal magnetic component and a ring-shaped external magnetic component. The external magnetic component surrounds the internal magnetic component, and there is a gap between the two components. A magnetic field is generated between the external and internal magnetic components to act on the fluid. This fluid magnetization method involves introducing the fluid into the magnetization apparatus, allowing it to be magnetized as it flows through a magnetically filled fluid channel formed by the apparatus, thus stimulating its internal energy before flowing out. The fluid channel formed by this magnetization apparatus is curved, so the distance and time for the fluid to flow through it are longer than in a straight-through fluid channel, resulting in more thorough and uniform magnetization and a more significant energy-saving and emission-reduction effect.

[0005] Chinese patent application publication number CN101113039A discloses a magnetized fluid processor, which consists of a magnetic block, a pipe clamp, a fluid pipeline, a shielding sleeve, and a connector. It is applicable to the technical field of magnetizing fluids such as water and liquid fuels. According to the different processing requirements of different fluids, the magnetic poles of the magnetic block are divided into positive and negative magnetic poles facing the fluid pipeline respectively. Two unconnected fluid pipelines are installed for both positive and negative magnetization treatments. The magnetic block is installed in the middle of the two fluid pipelines to obtain the fluid with both positive and negative magnetic pole treatment effects at the same time.

[0006] However, the aforementioned technologies still have certain technical problems. For example, the solution disclosed in patent application publication number CN87107681A requires a rotary drive mechanism, which leads to a complex structure, requires an external energy supply, increases the power consumption of the device, and introduces potential failure points, failing to achieve fluid processing while simplifying the structure and reducing energy consumption. The solution disclosed in patent application publication number CN107089711A uses an internal and external magnetic component enclosure, resulting in a relatively large structure that increases installation difficulty and cost. Furthermore, its fluid channel is curved, which, while extending the action time, fails to achieve the synergistic effect of magnetic field and fluid dynamic turbulence within a single compact component, limiting the improvement in shearing and atomization effects on fluids (especially fuel). The solution disclosed in patent application publication number CN101113039A uses pipe clamps to fix the magnetic block or places the magnetic block in the middle of the pipeline. This method only provides a static magnetic field and lacks active turbulence and shearing design for the fluid. When fluid flows through, the fluid near the boundary layer cannot be sufficiently magnetized and disturbed, resulting in uneven treatment effects and difficulty in achieving significant changes in the physical properties of the fluid. In particular, the effect on improving fuel atomization particle size and promoting molecular activity is limited. Utility Model Content

[0007] In view of the technical problems of high device complexity and poor fluid treatment effect in related technologies, this application provides a fluid magnetization treatment device.

[0008] This application provides a fluid magnetization treatment device, which adopts the following technical solution: A fluid magnetization treatment apparatus, comprising: The pipe has a smooth inner wall with a surface roughness of less than or equal to 3.2 micrometers; A magnetically polarized disruptor is disposed inside the pipe. The magnetically polarized disruptor includes a rugby ball-shaped permanent magnet body, a first disruptor plate group, and a second disruptor plate group. The rugby ball-shaped permanent magnet body has a first inclined surface and a second inclined surface. The first disruptor plate group is disposed on the first inclined surface and includes a plurality of first disruptor plates arranged at intervals in a counterclockwise direction. The second disruptor plate group is disposed on the second inclined surface and includes a plurality of second disruptor plates arranged at intervals in a clockwise direction. A pressurized gap is formed between the first disruptor plate group and the second disruptor plate group.

[0009] By employing the above technical solution, the smooth inner wall of the pipeline reduces the frictional resistance encountered by the fluid during passage. The magnetically polarized turbulent element, installed inside the pipeline, utilizes the opposite tilting directions of its first and second turbulent element groups to create a violently rotating flow field, enhancing the turbulence of the fluid. Simultaneously, the high-intensity magnetic field generated by the rugby ball-shaped permanent magnet magnetizes the fuel fluid. This solution achieves a multiplier effect through the spatiotemporal synergy of the magnetic field and the flow field: when the fuel fluid flows through the magnetically polarized turbulent element, it is first guided by the first turbulent element group (tilted counterclockwise) to form a counterclockwise rotating flow field and undergoes pre-magnetization; subsequently, when flowing through the pressurized gap formed between the first and second turbulent element groups, it is rapidly accelerated and placed in the equatorial region where the magnetic field of the rugby ball-shaped permanent magnet is strongest, experiencing the combined effects of strong magnetization and high-speed shearing; finally, the second turbulent element group (tilted clockwise) forces the fluid to rotate in the opposite direction, generating microscale turbulence through the violent turning of the flow field to achieve uniform mixing. This temporal and spatial coupling of 'pre-magnetization-strong magnetization / shear-reverse rotation mixing' overcomes the limitations of single magnetization or turbulence. Experimental data shows that this device can reduce the Sauter mean diameter (SMD) of fuel by approximately 40.8%, viscosity by approximately 17.1%, surface tension by approximately 16.5%, and fluid conductivity by approximately 172%. Even a 15.4% reduction in long-chain alkanes (C16-C20) content was observed. When applied to engine bench testing, it achieves an approximately 5.3% improvement in combustion efficiency, a 6.9% reduction in fuel consumption, a 39.6% reduction in CO emissions, and a 37.2% reduction in soot emissions. Furthermore, the device is compact, requires no external energy source, and resolves the contradiction between fluid handling efficiency and device complexity in related technologies. It can efficiently promote combustion or improve reaction efficiency, significantly reducing energy consumption and pollutant emissions.

[0010] Optionally, the width of the pressurized gap is set to 0.5 to 2.0 mm.

[0011] By adopting the above technical solution, a pressurized gap with a width of 0.5 to 2.0 mm is formed between the first and second baffle groups. According to fluid dynamics simulation, when the fuel fluid flows through the pressurized gap, the flow velocity can be accelerated to 1.5 to 3.0 times the mainstream velocity, generating a strong high-speed shear effect. This helps to break up fluid clusters, reduce viscosity (about 17.1%), and even promote the breakage of some long-chain alkanes (reducing the content by about 15.4%), further enhancing the turbulence and activity of the fluid.

[0012] Optionally, the number of the first spoiler and the second spoiler is 3 to 12.

[0013] Using the above technical solution, the number of both the first and second baffles is set to 3 to 12. This number setting helps to realize the function of the first and second baffle groups in forming a rotating flow field for the fuel fluid.

[0014] Optionally, the number of the first spoiler and the second spoiler is 5 to 8.

[0015] By adopting the above technical solution, the number of both the first and second baffles is set to a more preferred 5 to 8 pieces, which can increase the turbulence of the flow field by 30% to 50% with only an increase of 5% to 10% in pressure drop, thus achieving the optimal "high disturbance - low resistance" effect.

[0016] Optionally, the aspect ratio of the rugby ball permanent magnet body is set to 1.5 to 2.5.

[0017] By adopting the above technical solution, setting the aspect ratio of the rugby ball permanent magnet body to 1.5 to 2.5 helps to optimize the flow field distribution of the fuel fluid, allowing the fuel fluid to flow more smoothly through the magnetically polarized disturbance.

[0018] Optionally, the tilt angle of the first spoiler and the second spoiler is set to 30 to 60 degrees.

[0019] By adopting the above technical solution, setting the tilt angle of the first and second baffles to 30 to 60 degrees can achieve efficient conversion of axial fluid kinetic energy into tangential rotational kinetic energy, ensure that the fluid has sufficient rotational angular velocity, achieve a good turbulence effect, and control a reasonable pressure drop, thus achieving the best trade-off between efficient rotational motion and reasonable pressure drop control.

[0020] Optionally, a plurality of the magnetically polarized spoilers are arranged along the axial direction of the pipe.

[0021] By adopting the above technical solution, multiple magnetically polarized turbulent elements are arranged along the axial direction of the pipeline, which can extend the processing time of the fuel fluid and allow the fluid to be more fully subjected to the magnetic field and turbulence, thereby further improving the processing effect. Optionally, the distance between adjacent magnetically polarized turbulent elements is 3 to 5 times the inner diameter of the pipeline.

[0022] By adopting the above technical solution, the distance between adjacent magnetically polarized turbulent elements is 3 to 5 times the inner diameter of the pipe. Under this preferred arrangement spacing, the turbulence intensity moderately decreases before the fluid enters the next magnetically polarized turbulent element, the flow field tends to stabilize, and the magnetization and activation state of the molecules remains at a high level, thereby achieving a step-by-step accumulation of treatment effects.

[0023] Optionally, the end of the pipe is provided with a nozzle housing, the shape of which is adapted to the shape of the magnetically polarized disruptor to bind and position the magnetically polarized disruptor.

[0024] By employing the above technical solution, a nozzle housing is installed at the end of the pipe. The shape of the nozzle housing is adapted to the shape of the magnetically polarized disruptor, thus tightly securing and positioning the magnetically polarized disruptor. This design achieves stable positioning without requiring additional support structures, thereby simplifying the device structure, making the device more compact, and improving the system's reliability.

[0025] Preferably, the nozzle housing is connected to the pipe via a threaded or snap-fit ​​structure.

[0026] Using the above technical solution, the nozzle housing is connected to the pipeline through a threaded or snap-fit ​​structure, which facilitates installation and disassembly and ensures stable clamping of the magnetically polarized turbulent particles.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the structure of the magnetically polarized turbulent, a spatiotemporal match between the magnetic field gradient and the flow field shear rate is achieved: a process of counterclockwise rotation (pre-magnetization) → pressurized gap acceleration (strong magnetization + shearing) → clockwise reverse rotation (turbulent mixing), enabling the activity of fluid molecules to be excited within microseconds. Experiments show that this design can reduce the fuel atomized particle size (SMD) by approximately 40.8%, improve combustion efficiency by approximately 5.3%, and reduce CO emissions by approximately 39.6%. This compact device requires no external energy source and, compared to related technologies, resolves the contradiction between fluid treatment efficiency and device complexity.

[0028] 2. By forming a pressurized gap with a width of 0.5 to 2.0 mm between the first and second baffle groups, fluid dynamics simulations have verified that when the fuel fluid flows through the pressurized gap, the flow velocity can be accelerated to 1.5 to 3.0 times the mainstream velocity, generating a strong high-speed shear effect, which helps to break up fluid clusters, reduce viscosity (about 17.1%), and even promote the breakage of some long-chain alkanes (reducing the content by about 15.4%), further enhancing the turbulence and activity of the fluid.

[0029] 3. Arranging multiple magnetically polarized turbulent elements along the axial direction of the pipeline, with the distance between adjacent magnetically polarized turbulent elements being 3 to 5 times the inner diameter of the pipeline, can extend the processing time of the fuel fluid, allowing the fluid to be more fully subjected to the magnetic field and turbulence, thereby further improving the processing effect.

[0030] 4. By installing a nozzle housing at the end of the pipe, and utilizing the shape of the nozzle housing to match the shape of the magnetically polarized disruptor, the magnetically polarized disruptor is tightly bound and positioned. This design achieves stable positioning without requiring additional support structures, thus simplifying the device structure, making the device more compact, and improving the system's reliability.

Detailed Implementation

[0034] The following combination Figure 1 - Figure 2 This application will be described in further detail.

[0035] This application discloses a fluid magnetization treatment device.

[0036] Figure 1 A schematic diagram of a fluid magnetization treatment device according to an embodiment of this application is shown. Figure 1 The hollow arrow in the image indicates the direction of fluid flow. (For example...) Figure 1 As shown, the fluid magnetization treatment device includes a pipe 10 and a magnetically polarized disruptor 20. The pipe 10 is used to transport fuel fluid (e.g., fuel oil and combustion-supporting gas), and the magnetically polarized disruptor 20 is disposed within the pipe 10 to create a rotating flow field in the fuel fluid flowing through it, generating a magnetic field to magnetize the fuel fluid, thereby improving the dispersion and activity of the fuel fluid and promoting combustion or reaction efficiency.

[0037] In some embodiments, the magnetically polarized spoiler 20 includes a rugby ball-shaped permanent magnet body 21, a first spoiler group, and a second spoiler group.

[0038] The rugby ball-shaped permanent magnet body 21 is made of high-strength permanent magnet materials, such as neodymium iron boron (NdFeB) or samarium cobalt (SmCo) permanent magnet materials, which can generate strong magnetic fields. The rugby ball-shaped permanent magnet body 21 has a first inclined surface 21a and a second inclined surface 21b, with a surface magnetic field strength of 0.5 to 1.5 T and an aspect ratio of 1.5 to 2.5. The shape design of the rugby ball-shaped permanent magnet body 21 helps optimize the flow field distribution of the fuel fluid, allowing the fuel fluid to flow more smoothly through the magnetically polarized disturbance 20. For example, the rugby ball-shaped permanent magnet body 21 can be prepared first by sintering into a cylindrical or approximately spherical blank magnet. Then, precision grinding and polishing are performed using tools such as diamond grinding wheels to process the blank into a rugby ball shape with a precise aspect ratio and the first and second inclined surfaces 21a and 21b.

[0039] Here, the range of surface magnetic field strength (0.5 to 1.5 T) is crucial for achieving the desired technical effect. If the magnetic field strength is below 0.5 T, the polarization effect and Lorentz force on fluid molecules are weak, making it difficult to effectively reduce fluid viscosity (the viscosity reduction rate is positively correlated with the magnetic field strength). If it is above 1.5 T, although the effect may be slightly enhanced, the manufacturing cost of permanent magnet materials (such as high-performance sintered NdFeB) and the difficulty of magnetization will increase dramatically, resulting in diminishing marginal benefits. Experiments using a magnetic field strength of 1.2 T show that the treated fluid conductivity can increase by 172%, the absolute value of the Zeta potential increases by 132%, viscosity decreases by 17.1%, and surface tension decreases by 16.5%. Molecular dynamics simulations also show that a 1.2 T magnetic field can increase the molecular dipole moment by 18.3% and decrease the HOMO-LUMO band gap by 0.15 eV, significantly enhancing molecular activity. Therefore, 0.5 to 1.5 T is the optimal range for balancing treatment effectiveness and economic cost.

[0040] The aspect ratio (length to maximum diameter) of the rugby ball-shaped permanent magnet body 21 is set to between 1.5 and 2.5, a result of hydrodynamic optimization. If the aspect ratio is less than 1.5, the body is too "short and stout," approaching a sphere, resulting in significant form drag when fluid flows through it, leading to substantial energy loss and pressure drop. If the aspect ratio is greater than 2.5, the body is too "slender," which, while improving streamlinedness, results in an excessively long axial distance between the first and second baffle groups, weakening the coupling effect between the shear effect at the pressurization gap 24 and the rotational effect of the two baffle groups. The range of 1.5 to 2.5 ensures good streamlinedness (reducing pressure drop) while maintaining a compact spatial arrangement of the baffle groups and the pressurization gap, achieving optimal synergistic turbulence and shearing effects.

[0041] The first set of baffles is disposed on the first inclined surface 21a and includes a plurality of first baffles 22 arranged at counterclockwise angles. The number of the first baffles 22 is 3 to 12 (preferably 5 to 8), and the inclination angle is set to 30 to 60 degrees. The first baffles 22 can be disposed on the first inclined surface 21a of the rugby ball-shaped permanent magnet body 21 by welding or integral molding, thereby ensuring the stability of the baffles.

[0042] The second spoiler assembly is disposed on the second inclined surface 21b and includes a plurality of second spoilers 23 arranged at clockwise angles. The number of the second spoilers 23 is also 3 to 12 (preferably 5 to 8), and the inclination angle is also 30 to 60 degrees. Similarly, the second spoilers 23 are fixed to the second inclined surface 21b by welding or integral molding.

[0043] The number of turbulence deflectors is a key parameter for balancing turbulence effect and flow resistance. Based on computational fluid dynamics (CFD) simulations, if the number of deflectors is less than three, the applied rotational torque to the fluid is insufficient, making it difficult to form an effective rotating flow field. If the number of deflectors is more than twelve, the flow channels between the deflectors become too narrow, leading to a sharp increase in flow resistance (pressure drop) and increased manufacturing costs. Simulation results show that within the preferred range of 5 to 8 deflectors, the device can increase the turbulence intensity of the flow field by 30% to 50% with only a 5% to 10% increase in pressure drop, achieving the optimal "high turbulence - low resistance" effect.

[0044] The tilt angle of the baffles (30 to 60 degrees) determines the conversion efficiency of axial fluid kinetic energy to tangential rotational kinetic energy. If the tilt angle is less than 30 degrees, the tangential component is too small, the fluid rotational angular velocity is insufficient, and the turbulence effect is poor. If the tilt angle is greater than 60 degrees, the frontal "windward" area of ​​the baffles facing the incoming flow is too large, the axial drag increases significantly, and the fluid tends to flow around rather than rotate, which also reduces the processing efficiency. Bench tests using a 45-degree tilt angle achieved significant technical results. Therefore, a tilt angle range of 30 to 60 degrees is the optimal compromise between achieving efficient rotational motion and controlling a reasonable pressure drop.

[0045] A pressurized gap 24 is formed between the first and second baffle groups, and the width of the pressurized gap 24 is set to be between 0.5 and 2.0 mm. When the fuel fluid flows through the pressurized gap 24, it will accelerate the flow and generate a shear effect.

[0046] The width of the pressurized slit 24 (0.5 to 2.0 mm) is crucial for generating the shear effect. The pressurized slit 24 forms the "throat" of the flow channel; according to Bernoulli's principle, the fluid must accelerate when passing through it. If the slit width of the pressurized slit 24 is less than 0.5 mm, the flow channel is too narrow, resulting in extremely high flow resistance and easy clogging by impurities in the fluid. If the slit width is greater than 2.0 mm, the change in the cross-sectional area of ​​the flow channel is not significant, the acceleration effect is weak, and it is impossible to generate sufficient flow velocity (e.g., 1.5-3.0 times the mainstream velocity), leading to insufficient shear rate and difficulty in effectively breaking up fluid clusters and droplets. A slit width of 0.5 to 2.0 mm can generate the maximum shear effect within a controllable pressure drop range. Experiments have shown that this design can reduce the SMD of atomized particles by 40.8%, with a 65% reduction in the proportion of coarse droplets larger than 50 μm, mainly due to the high-speed shearing action generated by the pressurized slit 24.

[0047] The combination logic of the first and second baffle groups is as follows: by using opposite tilt directions, the fuel fluid forms a rotating flow field. When the fluid first passes through the first baffle group, it generates a counterclockwise rotating motion, and when it passes through the second baffle group, it generates a clockwise rotating motion. This rotating flow field can enhance the turbulence of the fluid, and combined with the magnetic field effect of the rugby ball-shaped permanent magnet body, it can better improve the physical properties of the fluid.

[0048] It should be understood that the technical effects of the embodiments of this application do not stem from the simple superposition of the aforementioned individual technical features, but rather from the synergistic effect of the magnetic field and the complex flow field. Its working mechanism is specifically as follows: (1) First-stage rotation and magnetization: The fuel fluid first flows through the first turbulence plate group (e.g., tilted counterclockwise) and is forced to generate counterclockwise rotation. While rotating, the fluid is pretreated by a strong magnetic field on the first inclined surface 21a of the rugby ball-shaped permanent magnet body 21.

[0049] (2) Accelerated Shearing and Strong Magnetization: The rotating fluid then enters the narrow pressurized slit 24. Here, the fluid is rapidly accelerated (the flow rate can reach 1.5-3.0 times the mainstream velocity), generating extremely high shear rates. At the same time, this pressurized slit 2 is located in the region of the strongest magnetic field of the rugby ball (usually near the "equator"). Under the dual action of high-speed shearing and strong magnetic field, the molecular clusters of the fluid are torn apart, the viscosity and surface tension decrease significantly, the molecular chains are stretched or even broken, and the electrical conductivity soars.

[0050] (3) Second-order reverse rotation and turbulent dissipation: The sheared fluid then impacts the second set of turbulent vanes. This set of vanes applies a torque in the opposite direction to the fluid, forcing it to rotate from counterclockwise to clockwise. This dramatic reversal of rotation direction generates strong vortex shedding and microscale turbulence in the wake region, resulting in extremely uniform mixing and dispersion of the magnetized and sheared fluid molecules, thereby achieving a significant reduction in atomized particle size and a substantial increase in activity.

[0051] This "rotation-shearing-reverse rotation" flow field design is highly coupled in space with the "pre-magnetization-strong magnetization-hybrid magnetization" magnetic field layout, achieving a synergistic enhancement effect of 1+1>2, which is something that related technologies (such as simple magnetization or simple turbulence) cannot achieve.

[0052] In some embodiments, the pipe 10 may be a pressurized pipe for transporting fuel fluid, typically a metal pipe (e.g., steel or copper) with good pressure resistance and sealing properties. The inner wall of the pipe 10 may be smoothed to form a smooth inner wall. Here, the term "smooth inner wall" refers to the inner surface of the pipe in contact with the fluid having a low roughness to reduce frictional resistance experienced by the fluid. For example, the surface roughness of the smooth inner wall is less than or equal to 3.2 micrometers. A nozzle housing 11 may be provided at the end of the pipe 10. The nozzle housing 11 is fitted and positioned to fit the shape of the magnetically polarized disruptor 20, thus simplifying the device structure, eliminating the need for additional support structures, and achieving stable positioning of the magnetically polarized disruptor 20 while making the device more compact. The nozzle housing 11 is connected to the pipe 10, for example, by a threaded or snap-fit ​​structure to ensure uniform clamping force. This connection method facilitates installation and disassembly while ensuring stable clamping of the magnetically polarized disruptor.

[0053] Optionally, a plurality of magnetically polarized turbulence generators 20 are arranged along the axial direction of the pipe 10. The distance between adjacent magnetically polarized turbulence generators 20 is preferably 3 to 5 times the inner diameter of the pipe 10. This can extend the processing time of the fuel fluid and allow the fluid to be more fully subjected to the magnetic field and turbulence.

[0054] When multiple magnetically polarized turbulence disruptors 20 are arranged axially along the pipe 10, a distance of 3 to 5 times the pipe's inner diameter (3D-5D) is crucial for achieving synergistic effects. If the distance is less than 3D, the wake turbulence generated by the previous disruptor has not yet fully developed and dissipated, and the fluid enters the next disruptor in a highly turbulent state, leading to poor flow stability and excessively high total pressure drop. If the distance is greater than 5D, the turbulence effect generated by the previous disruptor has largely attenuated, and the magnetization "memory" effect of fluid molecules (i.e., the time spent maintaining the polarized state) begins to decline, resulting in the inability to effectively synergize the treatment effects and losing the significance of "relay" enhancement. A distance of 3D-5D allows the turbulence intensity to moderately decrease before the fluid enters the next disruptor, the flow field to tend to stabilize, and the magnetization and activation state of the molecules to remain at a high level, thereby achieving a step-by-step accumulation of treatment effects.

[0055] The following is a detailed description of the comparative verification experiments of some core parameters of the embodiments of this application. The test objects and parameters are shown in Table 1.

[0056] Table 1 The fluid medium used in this experiment was #0 diesel oil, with a density of 830 kg / m³. 3The initial viscosity was 3.2 mPa·s, and the initial Sauter mean diameter (SMD) was 85 μm. The SMD was measured using a Mastersizer 3000 laser particle size analyzer, with a testing range of 0.1-3500 μm and an accuracy of ±2%. Viscosity was measured using a Brookfield DV2T rotational viscometer, with a test temperature set at 40℃ and a rotation speed of 60 rpm. The engine bench test equipment used a WP10.336 diesel engine with a rated power of 247 kW and a rotation speed of 1900 rpm. Carbon monoxide (CO) concentration was measured using a Horiba MEXA-7100DEGR emission analyzer, and soot emissions were measured using an AVL 415S smoke meter. The test conditions were set as follows: diesel flow rate 20 L / h, pipe inner diameter 20 mm, test duration 2 hours, and each test was repeated 3 times with the average value taken. The test results are shown in Table 2.

[0057] Table 2 Comparative experiments show that in Comparative Example 2, when only a static magnetic field is applied, the Sauter mean diameter (SMD) and viscosity decrease slightly (9.9% and 6.2%, respectively), with limited emission improvement. This indicates that a single magnetic field has a weak effect on altering the physical properties of the fluid. Comparative Example 3, by generating a rotating flow field through mechanical turbulence, shows a greater reduction in SMD and viscosity (20.0% and 9.4%, respectively), with a more significant emission improvement. This demonstrates that turbulence promotes atomization and combustion better than a single magnetic field. In the embodiments of this application, the SMD decreased by 40.6% (far exceeding the 30.0% of Comparative Examples 2 and 3), viscosity decreased by 17.2% (far exceeding the 15.6% of Comparative Examples 2 and 3), and carbon monoxide (CO) and soot emissions decreased by 39.3% and 37.2%, respectively (significantly higher than the 36.6% and 32.9% of Comparative Examples 2 and 3, respectively). This application achieves a synergistic effect of 1+1>2 by utilizing the high-intensity magnetic field (1.2T) generated by the rugby ball-shaped permanent magnet body and the dynamic flow field of "counterclockwise rotation-pressure shearing-clockwise reverse rotation". The coupling effect of magnetic field polarization of fluid molecules (reducing surface tension and promoting the breaking of long-chain alkanes) and turbulent mixing enhanced by turbulence (breaking droplets and improving atomization uniformity) is the core factor that makes its performance superior to that of a single magnetic field or a single turbulence.

[0058] In summary, the embodiments of this application resolve the contradiction between effect and complexity through a technical contradiction matrix: the flow field design applies the principle of asymmetry (counterclockwise / clockwise tilt) and the principle of dynamism (flow field reversal), the magnetic field layout applies the principle of segmentation (pre-magnetization-strong magnetization-mixing), and realizes the feedback of the force flow (shear stress) and electron flow (magnetic field polarization) to achieve the proof process of the force flow (shear stress) and electron flow (magnetic field polarization), and the shear rate feedback of the pressurized gap reduces viscosity.

[0059] The implementation principle of the fluid magnetization treatment device in this application embodiment is as follows: Through the special structural design of the magnetically polarized turbulence generator 20, the fuel fluid forms a rotating flow field and is subjected to shearing effects when flowing through it. Combined with the magnetic field effect of the rugby ball-shaped permanent magnet body 21, the dispersion and activity of the fuel fluid can be effectively improved. The passive clamping design of the nozzle housing 11 simplifies the device structure and improves reliability. The arrangement of multiple magnetically polarized turbulence generators 20 extends the processing time and further improves the processing effect. Compared with related technologies, this device solves the contradiction between fluid treatment effect and device complexity, and has the advantages of compact structure, high processing efficiency, and low energy consumption. It can significantly improve combustion or reaction efficiency and reduce energy consumption and pollutant emissions.

[0060] This application also discloses a fluid magnetization treatment method, which is mainly based on the fluid magnetization treatment device in the above embodiments.

[0061] Figure 2 A schematic flowchart of a fluid magnetization treatment method according to an embodiment of this application is shown. Figure 2 As shown, the fluid magnetization treatment method includes the following steps: S1. A magnetically polarized spoiler 20 is provided, the magnetically polarized spoiler 20 including a rugby ball-shaped permanent magnet body 21, a first spoiler plate group, and a second spoiler plate group. The rugby ball-shaped permanent magnet body 21 has a first inclined surface 21a and a second inclined surface 21b; the first spoiler plate group is disposed on the first inclined surface 21a and includes a plurality of first spoiler plates 22 arranged at intervals in a counterclockwise direction; the second spoiler plate group is disposed on the second inclined surface 21b and includes a plurality of second spoiler plates 23 arranged at intervals in a clockwise direction; a pressurized gap is formed between the first spoiler plate group and the second spoiler plate group.

[0062] In step S1, it is necessary to prepare a magnetically polarized turbulent 20 that meets the requirements, ensure that the material and magnetic field strength of the rugby ball-shaped permanent magnet body 21 meet the standards, and that the number, tilt angle and other parameters of the first turbulent plate 22 and the second turbulent plate 23 are also within the specified range.

[0063] S2. Place the magnetically polarized disruptor 20 inside the pipe 10.

[0064] In step S2, multiple magnetically polarized deflectors 20 can be arranged along the axial direction of the pipe 10, with the distance between adjacent magnetically polarized deflectors 20 being 3 to 5 times the inner diameter of the pipe 10. Furthermore, a nozzle housing 11 is provided at the end of the pipe 10, the shape of which is adapted to the shape of the magnetically polarized deflectors 20, allowing the magnetically polarized deflectors 20 to be positioned and tightened at the nozzle housing 11. During installation, it is essential to ensure the accurate positioning of the magnetically polarized deflectors 20 and a tight connection between the nozzle housing 11 and the pipe 10 to ensure uniform tightening force.

[0065] S3, transport fuel fluid through pipeline 10.

[0066] In step S3, the pipe 10 is generally a metal pipe 10, which has good pressure resistance and sealing performance, ensuring stable transportation of the fuel fluid. During the transportation process, the flow rate and pressure of the fluid must be controlled to ensure the subsequent treatment effect.

[0067] S4. The first and second turbulence plate groups make the fuel fluid flowing through the magnetically polarized turbulence generator 20 form a rotating flow field, and the fuel fluid is magnetized by the magnetic field generated by the rugby ball-shaped permanent magnet body 21.

[0068] In step S4, when the fuel fluid first passes through the first set of turbulence vanes, it generates a counterclockwise rotational motion, and when it passes through the second set of turbulence vanes, it generates a clockwise rotational motion. This rotating flow field enhances the turbulence of the fluid. At the same time, the magnetic field of the rugby ball-shaped permanent magnet acts on the fuel fluid, thereby improving the dispersion and activity of the fuel fluid, promoting combustion or increasing reaction efficiency.

[0069] The implementation principle of this embodiment is as follows: This fluid magnetization treatment method, through a reasonable arrangement of steps, utilizes the cooperation of magnetically polarized disruptors 20 and pipes 10 to create a rotating flow field and subject the fuel fluid to a magnetic field during flow, thereby improving the fluid's dispersibility and activity. The arrangement of multiple magnetically polarized disruptors 20 and the clamping and positioning design of the nozzle housing 11 extend the treatment time and improve the stability of the treatment. Compared with related technologies, this method resolves the contradiction between treatment efficiency and energy consumption, requires no external energy source, and achieves highly efficient fluid treatment through passive design. It has advantages such as simplicity, low cost, and good results, and can effectively improve combustion or reaction efficiency while reducing energy consumption and pollutant emissions.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
