Description

Technical Field

[0001] The present invention mainly relates to the technical field related to petroleum desulfurization treatment, and specifically, it is a multiphase flow reactor hydraulic power station in petrochemical industry. Background Art

[0002] The high-gravity desulfurization line for petroleum transportation is a device or system used for petroleum processing and treatment. It is mainly used to remove sulfides (such as hydrogen sulfide, organic sulfides, etc.) in petroleum to improve the quality of fuel and environmental friendliness.

[0003] For the high-gravity desulfurization line, it generally includes the following components: Cracker: The raw petroleum first enters the cracker, and undergoes a cracking reaction under high temperature and pressure to convert large molecular hydrocarbons into smaller hydrocarbon compounds; Separator: The cracked products enter the separator, and through pressure reduction and cooling, the gas, liquid and solid phases are separated. The sulfur products in petroleum mainly exist in the liquid phase. Sulfide extraction device: The liquid separator enters through the sulfide extraction device by a circulation method, and desulfurizing agents (such as methanol, aniline, etc.) are added, which react with the sulfides in the liquid petroleum to form sulfide compounds that are easy to separate. High-gravity settler: The petroleum after the desulfurization reaction enters the high-gravity settler, and the centrifugal force is used to accelerate the sedimentation speed, so as to effectively separate the liquid phase containing sulfides. Purification device: The separated sulfide compounds are processed through processes such as washing, dilution, and re-dissolution to obtain products with high purity and low residual sulfur. System control and monitoring: The entire high-gravity desulfurization line also includes system control and monitoring equipment, which is used to control process parameters such as temperature, pressure, and flow rate, and to conduct real-time monitoring and adjustment.

[0004] In the high-gravity desulfurization line for petroleum transportation, since there are many electrical equipment used and the power consumption is large, generally, corresponding power generation equipment needs to be configured to provide power for the entire desulfurization line. In the prior art, the construction cost of the power station is high, and when a failure occurs, it is easy to cause the electrical equipment on-site to stop operating. Summary of the Invention

[0005] To solve the deficiencies of the current technology, the present invention combines the existing technology and starts from practical applications to provide a hydraulic power station for the high-gravity desulfurization line of petroleum transportation, which has the advantages of being modularly combinable and having low requirements for the geographical environment, and can provide the required electrical energy for the electrical equipment in the petroleum desulfurization line.

[0006] The technical solution of the present invention is as follows: An oil transportation high-gravity desulfurization line hydraulic power generation station. The high-gravity desulfurization line includes a cracker, a separator, a sulfide extraction device, a high-gravity settler, a purification device, a system control and monitoring system; the power generation equipment generates electricity and transmits the electricity to the above-mentioned electrical equipment through an electrical control cabinet. The power generation unit includes multiple groups of power generation units. Multiple groups of power generation units can generate electricity independently. Multiple groups of power generation units are arranged at intervals in rows or columns in sequence. Each group of power generation units includes a closed hydraulic circulation pipeline formed by a left vertical pipeline, a right vertical pipeline, an upper horizontal pipeline, and a lower horizontal pipeline. A magnetic lifting device is arranged at the upper part of the left vertical pipeline, a magnetohydrodynamic accelerator is arranged at the upper part of the right vertical pipeline, a turbine is arranged at the lower part of the right vertical pipeline, and a generator is arranged outside the turbine. The hydraulic medium in the circulation pipeline is a conductive hydraulic medium. The hydraulic medium is lifted by the magnetic lifting device, accelerated by the magnetohydrodynamic accelerator, and then impacts the rotor of the turbine to rotate. The rotor of the turbine drives the generator to operate through a magnetic coupling.

[0007] Furthermore, the hydraulic medium is lifted upward in the left vertical pipeline by the magnetic lifting device, enters the right vertical pipeline through the upper horizontal pipeline, is accelerated by gravity and the magnetohydrodynamic accelerator in the right vertical pipeline, and then drives the turbine to operate at the bottom of the right vertical pipeline. After that, it returns to the left vertical pipeline through the lower horizontal pipeline to form a cycle.

[0008] Furthermore, the lifting device includes a hydraulic pipeline, a piston, a coupling guide frame, and a drive shaft; Among them, the hydraulic pipeline is used to dock with the left vertical pipeline. The piston is arranged in the hydraulic pipeline and is slidably matched with the hydraulic pipeline. A check valve is arranged in the middle of the piston. When the piston moves downward, the check valve opens to allow the hydraulic medium to enter the hydraulic pipeline above the piston. When the piston moves upward, the check valve closes to lift the hydraulic medium in the hydraulic pipeline above the piston upward; The coupling guide frame is sleeved outside the hydraulic pipeline. The coupling guide frame can reciprocate up and down along the length direction of the hydraulic pipeline under the action of the drive shaft. A first permanent magnet is arranged on the piston, and a second permanent magnet is arranged on the coupling guide frame. When the coupling guide frame moves up and down, the piston is driven to move synchronously through the magnetic force between the first permanent magnet and the second permanent magnet.

[0009] Furthermore, there are multiple first permanent magnets, which are evenly arranged circumferentially along the outer circle of the piston. There are multiple second permanent magnets, which are evenly arranged circumferentially along the coupling guide frame.

[0010] Furthermore, the coupling guide frame is guided and supported by several guide columns, and the coupling guide frame is slidably matched with the guide columns.

[0011] Further, a set of magnetic force pushing members are respectively arranged on both sides of the driving shaft. Each set of magnetic force pushing members includes a plurality of obliquely arranged permanent magnets disposed along the axial direction of the driving shaft. A third permanent magnet is further arranged on the coupling guide frame. The obliquely arranged permanent magnets of the magnetic force pushing members can apply a repulsive force for lifting to the third permanent magnet of the coupling guide frame, and the repulsive forces applied by the magnetic force pushing members on both sides are opposite to each other. The driving shaft is connected with a commutation driving member, and the commutation driving member is used for commuting the driving shaft so that the two sets of magnetic force pushing members act on the third permanent magnet alternately to realize the lifting control of the coupling guide frame.

[0012] Further, two driving shafts are provided and symmetrically distributed on both sides of the coupling guide frame.

[0013] Further, the magnetohydrodynamic accelerator includes an acceleration pipeline. The acceleration pipeline is integrally of a rectangular structure. A plurality of rectangular acceleration channels are arranged in the acceleration pipeline. A penetrating DC power line is applied between two opposite long sides of each acceleration channel, and a penetrating magnetic line is applied between two opposite short sides. The power line and the magnetic line are perpendicular. The conductive medium enters the acceleration channel from one end of the acceleration pipeline and is ejected from the other end of the acceleration pipeline to achieve acceleration.

[0014] Further, the multiple acceleration channels in the acceleration pipeline are arranged in a spaced array in sequence. Electrode plates are arranged on two opposite long sides of the acceleration channel. The electrode plates on one side are connected to the positive pole of the DC power supply, and the electrode plates on the other side are connected to the negative pole of the DC power supply. Magnetic steel is arranged on two opposite short sides of the acceleration channel. The inner sides of the magnetic steel on both sides are N pole and S pole respectively. The DC power line is applied through the electrode plates, and the magnetic line is applied through the magnetic steel.

[0015] Further, the electrode plates are arranged on the inner wall of the acceleration channel in contact with the conductive liquid medium, and the magnetic steel is arranged on the outer wall of the acceleration channel without contacting the conductive liquid medium.

[0016] Advantages of the present invention: 1. The power station of the present invention is mainly used to provide electric energy for the electrical equipment of the oil supergravity desulfurization line hydraulic power station. The power of the power station can reach 1 MW, meeting the electricity demand at the engineering site. The power station adopts a multi-group combination form. In the case of a single unit power of 0.5 MW, a power demand of 1 WM can be formed through a 2-row combination.

[0017] 2. The present invention recycles the hydraulic medium, with less consumption of the hydraulic medium, avoiding waste of the hydraulic medium. Through the arbitrary combination of single units, it is less affected by the geographical environment, is convenient to combine, each unit works independently, and is convenient for maintenance.

[0018] 3. The present invention abandons the traditional method of using a hydraulic pump to achieve the lifting and transportation of hydraulic medium in a pipeline. Instead, it adopts a brand-new mechanical transportation structure. When the coupling guide frame moves, the piston inside the pipeline is driven by magnetic coupling to achieve the lifting and transportation of the hydraulic medium. Compared with the method of using a pump for transportation, it is not limited by the lift and has a long transportation distance. Compared with the traditional mechanical method, the piston inside the pipeline is not directly connected to other mechanical structures. Therefore, the driving part can be entirely arranged outside the hydraulic pipeline, which is convenient for maintenance, disassembly, and assembly.

[0019] 4. The main lifting energy of the present invention is achieved through permanent magnets. Only a small amount of external input energy is required to turn the drive shaft to control the lifting and lowering of the piston inside the pipeline. The structure is stable and the energy consumption is small.

[0020] 5. The accelerator involved in the present invention can significantly increase the speed of the conductive hydraulic medium when it passes through the magnetic field and electric field in the channel by setting mutually perpendicular magnetic field lines and DC power lines. Thus, the efficient acceleration of the conductive hydraulic medium in the closed pipeline is realized. The accelerated hydraulic medium has a relatively high available kinetic energy. The overall structure is simple and the application scenarios are extensive. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0030] Referring to Figure 1 As shown in the embodiment of the present invention, a hydrodynamic power station for an oil transportation high-gravity desulfurization line is provided, which can achieve power generation with a power of 1WM. Specifically, the power station generates electric energy, and the electric energy is distributed through an electric energy control cabinet and then transported to the electrical equipment on the oil desulfurization line for power supply.

[0031] Referring to Figure 2 、 3 As shown, a hydrodynamic power station for an oil transportation high-gravity desulfurization line provided in this embodiment includes multiple groups of power generation units 10. Multiple groups of power generation units 10 can generate electricity independently, and multiple groups of power generation units 10 are arranged at intervals in rows or columns in sequence. This embodiment adopts the form of modular combination of power generation units 10. Each power generation unit 10 has an independent structure. The power of a single power generation unit 10 is 0.5MW or 0.65MW. For each additional group of power generation units 10, the power doubles. Therefore, the number of power generation units 10 used can be selected according to the actual application scenario and power demand, thereby completing a rapid design. In this embodiment, the structures of each group of power generation units 10 are the same. The independent structure is convenient for equipment maintenance and the construction of the power station. The power generation unit 10 has a good compact structure design, occupies a small space and has a high flexibility during assembly.

[0032] In this embodiment, a single group of power generation units 10 mainly includes a closed hydrodynamic circulation pipeline formed by a left vertical pipeline 6, a right vertical pipeline 7, an upper horizontal pipeline 8, and a lower horizontal pipeline 9. A magnetic lifting device 1 is arranged at the upper part of the left vertical pipeline 6, a magnetohydrodynamic accelerator 2 is arranged at the upper part of the right vertical pipeline 7, a turbine 3 is arranged at the lower part of the right vertical pipeline 7, and a generator 4 is arranged outside the turbine 3. The hydrodynamic medium in the circulation pipeline is a conductive hydrodynamic medium. The hydrodynamic medium is lifted by the magnetic lifting device 1, accelerated by the magnetohydrodynamic accelerator 2, and then impacts the rotor of the turbine 3 to rotate. The rotor of the turbine 3 drives the generator 4 to operate through a magnetic coupling 5.

[0033] In this embodiment, the circulating pipeline adopts a closed pipeline, and the pipeline is filled with a flowing conductive hydraulic medium. The hydraulic medium circulates and accelerates in the pipeline, impacts the rotor of the turbine 3 to make the turbine 3 operate, and the rotor of the turbine 3 drives the external vertical-axis permanent magnet generator 4 to operate through the magnetic coupler 5 to generate electric energy. In this embodiment, the flow of the hydraulic medium is mainly realized by the magnetic lifting device 1 and the magnetohydrodynamic accelerator 2 in this embodiment. In the vertical pipeline, the magnetic lifting device 1 can lift the hydraulic medium to generate a first speed. After being lifted, the hydraulic medium enters the upper horizontal pipeline 8, and enters the right vertical pipeline 7 through the end of the upper horizontal pipeline 8. In the right vertical pipeline 7, it moves downward under the first speed and the gravity of the hydraulic medium, and at the same time is secondarily accelerated by the magnetohydrodynamic accelerator. The accelerated hydraulic medium generates a high-speed jet to drive the turbine 3 to operate downward. Finally, it enters the lower horizontal pipeline 9 through the water outlet of the turbine 3, and enters the left vertical pipeline 6 at the end of the lower horizontal pipeline 9. In this way, the high-speed circulation of the hydraulic medium is realized, and the impact jet continuously acts on the turbine 3 to make the generator 4 continuously generate electricity. In this embodiment, due to the adoption of a closed pipeline structure, the turbine 3 and the generator 4 output torque through the magnetic coupler 5, without overload and leakage of the hydraulic medium, and operate smoothly with low noise.

[0034] This embodiment provides a magnetic lifting device 1, which mainly includes a hydraulic pipeline 11, a piston 12, a coupling guide frame 13, a drive shaft 14, etc. Among them, the hydraulic pipeline 11 is vertically arranged in the hydraulic transmission system. First connectors and second connectors are respectively arranged at both ends of the hydraulic pipeline 11. Through the first connectors and the second connectors, this section of the hydraulic pipeline 11 is butted with the left vertical pipeline 6 to form a closed-circuit hydraulic transmission pipeline. The magnetic lifting device 1 of this embodiment is mainly used to lift and accelerate the hydraulic medium upward in the vertically arranged hydraulic pipeline 11.

[0035] In this embodiment, the piston 12 is used to lift the hydraulic medium in the hydraulic pipeline 11. Specifically, the piston 12 can move up and down in the hydraulic pipeline 11. The piston 12 is made of rubber, and the outer ring fits with the inner wall of the hydraulic pipeline 11 to ensure the sealing performance. A one-way valve 15 is arranged in the middle of the piston 12. The piston 12 can slide up and down along the hydraulic pipeline 11. When the piston 12 moves downward, the one-way valve 15 automatically opens under the action of the liquid pressure in the hydraulic pipeline 11. At this time, the piston 12 moves downward, and the hydraulic medium in the lower hydraulic pipeline 11 enters the upper hydraulic pipeline 11 through the one-way valve 15. When the piston 12 moves upward, the one-way valve 15 is in a closed state. Therefore, when the piston 12 rises, it can push the upper hydraulic medium to lift and accelerate upward along the hydraulic pipeline 11. In this way, the piston 12 moves in a cycle to realize the vertical lifting of the hydraulic medium.

[0036] In this embodiment, the lifting movement of the piston 12 is mainly controlled by the coupling guide frame 13 and the drive shaft 14. To ensure that the hydraulic medium in the hydraulic pipeline 11 is not contaminated and for the convenience of later maintenance, both the coupling guide frame 13 and the drive shaft 14 are arranged outside the hydraulic pipeline 11. The specific connection relationship is as follows: The coupling guide frame 13 is sleeved outside the hydraulic pipeline 11. The coupling guide frame 13 is connected to the drive shaft 14 and can reciprocate up and down along the length direction of the hydraulic pipeline 11 under the action of the drive shaft 14. The coupling guide frame 13 and the piston 12 move synchronously by means of magnetic coupling. An annular mounting groove is circumferentially arranged on the outer periphery of the piston 12, and a plurality of first permanent magnets 16 are evenly arranged at intervals along the circumference in the annular mounting groove. A plurality of second permanent magnets 17 are evenly arranged at intervals along the circumference of the coupling guide frame 13. An attractive force is formed between the first permanent magnets 16 and the second permanent magnets 17. A plurality of magnet embedding grooves are arranged circumferentially on the coupling guide frame 13, and the second permanent magnets 17 are fixedly arranged in the corresponding magnet embedding grooves. In this structure, the piston 12 and the coupling guide frame 13 are respectively arranged inside and outside the hydraulic pipeline 11 and are not directly connected, and the force is transmitted through magnetic force. At this time, when the external coupling guide frame 13 moves upward under the action of the drive shaft 14, the coupling guide frame 13 synchronously drives the piston 12 to move upward through the magnetic force attracting the piston 12. When the coupling guide frame 13 moves downward under the action of the drive shaft 14, it drives the piston 12 to move downward, thus realizing the lifting control of the piston 12.

[0037] As a preferred solution of this embodiment, to ensure that the coupling guide frame 13 can move up and down smoothly, a corresponding guiding structure is provided for it in the vertical direction, and the guiding structure is realized by four guiding columns 18. The four guiding columns 18 are evenly arranged around the coupling guide frame 13. The two ends of the guiding columns 18 are respectively fixed by the first connecting piece and the second connecting piece at both ends of the hydraulic pipeline 11. Corresponding through holes are provided on the coupling guide frame 13 for the guiding columns 18, so that the coupling guide frame 13 can move up and down along the guiding columns 18 to ensure the movement guiding and stable support of the coupling guide frame 13.

[0038] In this embodiment, the coupling guide frame 13 is driven by the drive shaft 14 to move up and down. To ensure the smoothness of the movement, two sets of drive shafts 14 are adopted and symmetrically arranged on both sides of the coupling guide frame 13. The two sets of drive shafts 14 move synchronously to drive the coupling guide frame 13 to move up and down.

[0039] As a preferred solution of this embodiment, a magnetic force cooperation structure is adopted between the coupling guide frame 13 and the drive shaft 14. Specifically, both ends of the drive shaft 14 are supported by bearings and installed between the first connecting piece and the second connecting piece of the hydraulic pipeline 11. A set of magnetic force pushing pieces 19 are respectively arranged on both sides of the drive shaft 14. Each set of magnetic force pushing pieces 19 includes a plurality of obliquely arranged permanent magnets arranged along the axial direction of the drive shaft 14. A third permanent magnet mounting seat is arranged on one side of the coupling guide frame 13, and a third permanent magnet 110 is arranged in the third permanent magnet mounting seat. A repulsive force is generated between the obliquely arranged permanent magnets of the magnetic force pushing piece 19 and the third permanent magnet 110 of the coupling guide frame 13. This repulsive force is an oblique force, and the repulsive forces applied by the magnetic force pushing pieces 19 on both sides are opposite. Through the above structure, when one set of magnetic force pushing pieces 19 of the drive shaft 14 faces the position of the third permanent magnet 110, its obliquely arranged permanent magnet generates an obliquely upward repulsive force on the third permanent magnet 110. Through this acting force, the coupling guide frame 13 can be pushed upward. When the drive shaft 14 rotates 180°, the magnetic force pushing piece 19 on the other side applies a force towards the position of the third permanent magnet 110. At this time, the applied repulsive force is an obliquely downward repulsive force. Through this acting force, the coupling guide frame 13 can be pushed downward. In this way, only by controlling the drive shaft 14 to achieve continuous commutation of 180° can the reciprocating linear motion of the magnetic coupling frame be realized. In a specific implementation manner provided in this embodiment, the structure of the commutation drive member 111 for enabling the drive shaft 14 to achieve continuous rotation of 180° adopts motor control. The motor is arranged at the upper end of the drive shaft 14, and the rotation of the drive shaft 14 is driven to commutate by the rotation of the motor.

[0040] This embodiment provides a structure of a magnetohydrodynamic accelerator 2. The accelerator of this embodiment is mainly used to accelerate the conductive hydraulic medium in a closed pipeline. Both ends of the accelerator of this embodiment are connected to the right vertical pipeline 7. When the hydraulic medium passes through the parallel electric field and parallel magnetic field of this accelerator, it can be accelerated and jet out.

[0041] The conductive hydraulic medium accelerator of this embodiment mainly includes an acceleration pipeline 21. The outer shape of the acceleration pipeline 21 is a rectangular structure. A plurality of rectangular acceleration channels 22 are arranged in the acceleration pipeline 21. The acceleration channels 22 are rectangular structures with two long sides and two short sides. The number of acceleration channels 22 can be determined according to the actual medium flow rate. Each acceleration channel 22 is used to accelerate the conductive hydraulic medium. Specifically, penetrating DC power lines are applied between the two opposite long sides of each acceleration channel 22, and penetrating magnetic lines are applied between the two opposite short sides. The DC power lines and the magnetic lines are both arranged in parallel, and the DC power lines and the magnetic lines are at 90°. At this time, after the conductive hydraulic medium enters the acceleration channel 22 from one end of the acceleration pipeline 21, under the action of the electric field and magnetic field in the acceleration channel 22, it can be accelerated according to the Lorentz force principle. The accelerated conductive hydraulic medium jets out from the other end of the acceleration pipeline 21 to generate available kinetic energy.

[0042] In a specific arrangement provided in this embodiment, a plurality of acceleration channels 22 in the acceleration pipeline 21 are arranged in a spaced array in sequence. The acceleration pipeline 21 is processed and manufactured from a non-conductive nylon material. Electrode plates 23 are provided on both opposite long sides of the acceleration channel 22. The electrode plate 23 on one side is connected to the positive pole of a DC power supply, and the electrode plate 23 on the other side is connected to the negative pole of the DC power supply. The electrode plate 23 can be made of a steel plate and is arranged on the inner side wall of the acceleration channel 22 by means of inlaying or attaching. The electrode plate 23 is in direct contact with the conductive hydraulic medium. At the same time, the electrode plate 23 covers the entire inner wall along the length direction of the acceleration channel 22. Magnetic steels 24 are provided on both opposite short sides of the acceleration channel 22. The inner sides of the magnetic steels 24 on both sides are the N pole and the S pole respectively. The magnetic steels 24 on both sides are arranged on the outer wall of the acceleration channel 22 by means of inlaying or attaching and are not in direct contact with the conductive hydraulic medium, and the magnetic steels 24 cover the entire outer wall along the length direction of the acceleration channel 22.

[0043] In the above structure of this embodiment, an electric field is provided by the electrode plate 23, and a magnetic field is provided by the magnetic steel 24. The combined electric field and magnetic field formed by the two can accelerate the conductive hydraulic medium passing through.
