[0002] Crude oil is an important resource, playing a vital role in human production and daily life. With the large-scale exploitation of conventional oil, reserves are gradually depleting, highlighting the growing importance of unconventional oil resources. Shale oil, among unconventional oils, is characterized by its large reserves and wide distribution. Currently applied nanofluid flooding technology offers higher recovery rates, more stable pressure, and less formation damage; however, the dehydration process of the produced fluid is challenging, and the separation efficiency of electrocyclone flow field oil-water separators currently used for oil-water emulsion separation still needs improvement.

[0003] Therefore, it is necessary to develop a more efficient oil-water separation device to improve oil-water separation efficiency. Summary of the Invention

This device includes a hydrocyclone system, a rotating electric field system, a magnetic field system, an electric heating and insulation system, and a sealing system, thereby forming an electromagnetic-thermal composite field composed of a rotating electric field, a magnetic field, and a thermal field. This enables deep dehydration and effectively improves the oil-water separation speed and high oil-water separation efficiency.

[0005] The technical solution adopted in this invention is as follows:

The overflow pipe comprises an outer overflow pipe and an inner overflow pipe arranged coaxially, and the outer wall of the overflow pipe is provided with cyclone guide vanes. The hydrocyclone cavity includes a cylindrical section, a large conical section, a small conical section, and an underflow pipe arranged coaxially. The overflow pipe is coaxially placed inside the cylindrical section of the hydrocyclone, and the outer overflow pipe extends into the cylindrical section of the hydrocyclone and is connected in sequence to the cyclone guide vanes and the inner overflow pipe.

[0012] Furthermore, the rotating electric field system includes electrodes and an electrode sleeve. The electrodes include at least four electrode pillars arranged in an array, with the electrode pillars arranged parallel to each other along the axial direction. The electrode sleeve includes at least four electrode sleeve pillars arranged in an array, which wrap around the electrode pillars.

[0013] Furthermore, the electrode post is fully enclosed by the electrode sleeve near the swirl guide vane, and partially enclosed by the remaining electrode sleeve.

[0014] Furthermore, a sinusoidal electrical signal with a phase difference of 2π / N is applied to two adjacent electrode posts, where N is the number of electrode posts arranged in the array. The overflow pipe and the hydrocyclone cavity are grounded, generating a rotating electric field in the flow field within the cylindrical section of the hydrocyclone.

[0015] Furthermore, the overflow pipe, electrode, and electrode sleeve are connected by flanges, and a sealing gasket is installed between adjacent flanges.

[0016] Furthermore, the magnetic field system includes an electromagnet cavity, an electromagnet coil, an electromagnet coil frame, and an electromagnet core. The electromagnet core is located inside the electromagnet cavity, and the electromagnet coil frame is located outside the electromagnet core. The electromagnet coil is located on the electromagnet coil frame, and the electromagnet coil is connected to a DC power supply or an AC power supply.

[0017] Furthermore, the electric heating and insulation system includes an electric heating coil and an insulation layer. The electric heating coil is wound sequentially around the outside of the hydrocyclone inlet pipe, the cylindrical section of the hydrocyclone, the large conical section of the hydrocyclone, the small conical section of the hydrocyclone, and the underflow pipe of the hydrocyclone, and is covered with an insulation layer on the outside of the electric heating coil.

[0018] Furthermore, the cyclone guide vane includes at least four guide vanes, the root of the cyclone guide vane is connected to the outer wall surface of the overflow pipe of the oil-water cyclone separator, and the tip of the cyclone guide vane is in contact with the inner wall surface of the cylindrical section of the oil-water cyclone separator.

[0019] Furthermore, the swirl guide vane is designed using a geometric method, employing circular arc orthogonal blades, with the guideline composed of circular arcs and straight line segments, forming a gradually narrowing flow channel.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention applies a rotating electric field to the cylindrical section of an oil-water hydrocyclone separator using a rotating electric field system. This effectively promotes the coalescence of discrete phase droplets in the cylindrical section of the hydrocyclone and inhibits the breakage of large-diameter droplets.

This invention applies a magnetic field to the cylindrical section of an oil-water hydrocyclone separator using a magnetic field system, thereby regulating the movement behavior of droplets, increasing the probability of collisions between droplets, improving droplet coalescence efficiency, suppressing the breakup behavior of large droplets under an electric field, and promoting the coalescence of discrete phase droplets of the oil-water emulsion in the cylindrical section of the hydrocyclone.

[0023] 3. The present invention applies a thermal field to the oil-water hydrocyclone separator through an electric heating and heat preservation system, so that the hydrocyclone operates at the design temperature, reduces the viscosity of the oil-water emulsion, promotes the drainage of the liquid film when the discrete phase droplets in the oil-water emulsion approach each other, promotes the coalescence of the discrete phase droplets, and effectively improves the oil-water separation efficiency.

[0048] Combined with appendix Figure 1-20 This invention discloses a hydrocyclone separator that integrates multiple fields of electric, magnetic, and thermal synergy, comprising a hydrocyclone system, a rotating electric field system, a magnetic field system, an electric heating and insulation system, and a sealing system. The systems are as follows:

[0049] The hydrocyclone system includes an overflow pipe 100 and a hydrocyclone cavity 110. The overflow pipe 100 is equipped with an outer overflow pipe 101, an overflow pipe flange 102, a hydrocyclone guide vane 103, and an inner overflow pipe 104. The hydrocyclone cavity 110 is equipped with a hydrocyclone cavity flange 111, a hydrocyclone inlet pipe 112, an electromagnet connecting platform 113, an electrode sleeve groove 114, a cylindrical section 115 of the hydrocyclone, a large conical section 116 of the hydrocyclone, a small conical section 117 of the hydrocyclone, and an underflow pipe 118 of the hydrocyclone. The specific structure is as follows: Figure 4-5As shown in Figures 13-16, the overflow pipe 100 includes an outer overflow pipe 101, an overflow pipe flange 102, a cyclone guide vane 103, and an inner overflow pipe 104 arranged along the same centerline. The inner diameter of the outer overflow pipe 101 is larger than that of the inner overflow pipe 104 to prevent incompletely separated oil-water mixture from flowing out of the overflow pipe 100 when the overflow outlet is lower than the cylindrical section 115 of the hydrocyclone during installation. The hydrocyclone cavity 110 includes a hydrocyclone cavity flange 111, a hydrocyclone cylindrical section 115, a large conical section 116, a small conical section 117, and a hydrocyclone underflow pipe 118 arranged along the same centerline. The side wall of the cylindrical section 115 is connected to the hydrocyclone inlet pipe 112, which is arranged tangentially to the cylindrical section 115. The inner wall of the cylindrical section 115 is arranged tangentially to the cylindrical section 115. Four axially oriented electrode sleeve grooves 114 are evenly distributed in the circumferential direction to engage the electrode sleeves 212. Each electrode sleeve groove 114 is parallel to the axis of the hydrocyclone cavity 110. The four electrode sleeve grooves 114 are rotated at a certain angle along the circumference of the hydrocyclone cylindrical section 115 so that the hydrocyclone inlet pipe 112 does not pass through the electrode sleeve grooves 114, avoiding fluid flow line disturbance or leakage caused by electrode cutting due to the flow channel passing through the electrode grooves. Four electromagnet connecting platforms 113 are evenly distributed in the circumferential direction on the outer wall of the hydrocyclone cylindrical section 115. The end face of the electromagnet connecting platform 113 is parallel to the axial surface of the hydrocyclone, and the end faces of adjacent electromagnet connecting platforms 113 are perpendicular to each other. Four threaded holes are evenly provided in the circumferential direction of the end face of the electromagnet connecting platform 113 for fixing the magnetic field system 300.

[0050] More preferably, the diameter D of the cylindrical section of the hydrocyclone is calculated by the following formula:

[0051]

[0052] Where, q m For processing volume, m 3 / h;Δp m The maximum actual pressure drop is expressed in MPa; ρ l The density of the liquid phase is t / m³. 3 C w The concentration is the oil phase mass concentration, in %.

[0053] Cyclone section with nominal diameter D 115 c =D / 2.

[0054] Based on the nominal diameter D of the cylindrical section of the hydrocyclone. c And the diameter D of the cylindrical segment, and then the length L of the cylindrical segment are selected sequentially. y1 = 4 × D, length of the C7 segment Underflow tube inner diameter D u =0.33D C Length of small cone segment Underflow tube length L u =50×D u .

[0055] More preferably, in conjunction with appendix Figure 2-5 20. The swirl guide vane 103 comprises four guide vanes. The root of the swirl guide vane 103 is connected to the outer wall of the overflow pipe of the oil-water cyclone separator, thereby fixing the swirl guide vane 103. The tip of the swirl guide vane 103 contacts the inner wall of the cylindrical section 115 of the oil-water cyclone separator. The swirl guide vane 103 is designed using a geometric method, employing orthogonal circular arc blades. The guideline is composed of circular arc lines and straight line segments, forming a gradually narrowing flow channel to achieve fluid acceleration.

[0056] The equation for the root guideline of the swirl guide vane 103 is:

[0057]

[0058] The equation for the tip directrix of the swirl guide vane 103 is:

[0059]

[0060] Where (x, y) are the coordinates of the vortex guide vane root / tip directrix in a plane rectangular coordinate system, ρ is the radius of the arc segment of the vortex guide vane root directrix, (x0, y0) are the coordinates of the intersection point of the arc segment and the straight segment of the vortex guide vane root directrix, β1 and β2 are the angles between the straight segments of the inner and outer directrixes of the vortex guide vane root and the positive x-axis, K1 is the reciprocal of the slope of the straight segment of the vortex guide vane root directrix, R1 is the diameter of the vortex guide vane root, and R2 is the diameter of the vortex guide vane tip.

[0061] The radius ρ of the arc segment at the root guideline of the 103 swirl guide vane can be determined by the following formula:

[0062] ρ=L0 / (1-sinβ1)

[0063] Where L0 is the basic segment envelope arc length and β1 is the inner edge exit angle.

[0064] The basic segments of the inner and outer directrixes of the swirl guide vane 103 are related, but the exit angles β1 and β2 of the inner and outer directrixes of the guide vane are independent. When β2 = tan -1 When the angle is [(R1 / R2)tanβ1], the inner and outer directrixes are completely correlated, and β1 and β2 are not independent. When the exit angle β2 of the outer directrix is ​​greater than the exit angle β1 of the inner directrix, it is beneficial for the separation of the oil-water emulsion. The exit cross-sectional area is:

[0065]

[0066] Where δ1 and δ2 are the minimum thicknesses of the inner and outer edges of the guide vane outlet, respectively, and n is the number of guide vanes.

[0067] The blade envelope length L and h can be determined based on the overlap rate of the outer lines of two adjacent blades. Generally, the overlap rate of the outer lines of adjacent blades is (0.4~0.75)L.

[0068] The rotating electric field system includes an electrode 200 and an electrode sleeve 210. The electrode 200 is provided with an electrode terminal 201, an electrode flange 202, an electrode insulating layer 203, and an electrode post 204; the electrode sleeve 210 is provided with an electrode sleeve flange 211 and an electrode sleeve post 212. The specific structure is as follows... Figure 7-8 As shown in Figures 10-11, the electrode sleeve 210 is made of insulating material. The four electrode sleeve posts 212 of the electrode sleeve 210 are evenly arranged circumferentially, and each electrode sleeve post 212 is parallel to the axis of the electrode sleeve 210. A semi-enclosed electrode groove is formed on the side of the electrode sleeve post 212 near the electrode sleeve flange 211. This semi-enclosed electrode groove opens towards the side facing the overflow pipe 101, thus the electrode inside the semi-enclosed electrode groove is a bare electrode, improving the demulsification effect of the electric field. A closed electrode groove (square hole) is formed on the side away from the electrode sleeve flange 211. This closed electrode groove completely encloses the electrode, and its end face is also closed, insulating the electrode from the hydrocyclone wall and the hydrocyclone guide vane 103, preventing the hydrocyclone cavity 110 and the overflow pipe 100 from becoming energized, and avoiding electric shock accidents. The four electrode posts 204 of the electrode 200 are evenly arranged in the circumferential direction. Each electrode post 204 is parallel to the axis of the electrode 200. The radial thickness of the electrode post 204 is smaller in the section away from the electrode flange 202 to fit the square hole end of the electrode sleeve post 212. The electrode flange 202 of the electrode 200 is provided with four electrode insulating layers 203 evenly distributed in the circumferential direction, which divide the electrode 200 into four unconnected conductive areas. Each conductive area has one electrode post 204 and one electrode terminal 201. The electrode terminal 201 is connected to the outside of the electrode flange 202 and is evenly distributed in the circumferential direction.

[0069] A sinusoidal electrical signal with a phase difference of π / 2 is applied to two adjacent electrodes of the four electrode posts 204 of the electrode 200. The overflow pipe 100 and the hydrocyclone cavity 110 are grounded, generating a rotating electric field in the flow field within the cylindrical section 115 of the hydrocyclone.

[0070] Electrical signals can be applied to electrode 200 in the following manner: The four electrode posts of electrode 200 are named A, B, C, and D in a clockwise direction. A sinusoidal electrical signal with a phase difference of π / 2 is generated by a dual-channel signal generator and connected to electrode posts A and B respectively. The electrical signal connected to electrode post A is then connected to electrode post C after its phase is shifted by π using an inverter. Similarly, the electrical signal connected to electrode post B is connected to electrode post D using an inverter. Before connecting the electrical signals to each electrode post, the signals are first amplified by a power amplifier.

[0071] The magnetic field system 300 includes an electromagnet cavity 301, an electromagnet coil 302, an electromagnet coil frame 303, an electromagnet core 304, an electromagnet cavity wire hole 305, and an electromagnet cavity wire hole cover 306. The specific structure is as follows: Figure 17-19 As shown, the magnetic field system 300 includes an electromagnet cavity 301, an electromagnet coil frame 303, and an electromagnet core 304 arranged along the same center line. A cylinder connected to the electromagnet cavity 301 is located at the center of the electromagnet cavity 301, and the diameter of the cylinder is the same as the inner diameter of the electromagnet core 304. The electromagnet coil frame 303 is used to wind the electromagnet coil 302. An electromagnet cavity through-hole 305 is provided on the side wall of the electromagnet cavity 301, and the end face of the through-hole 305 is arranged parallel to the axial surface of the electromagnet cavity 301. Four evenly distributed threaded holes are provided on the end face of the through-hole 305. The through-hole 305 is connected to an electromagnet cavity through-hole cover 306 by screws. The through-hole cover 306 has two holes at its center with a diameter slightly larger than the diameter of the lead wire of the electromagnet coil 302. The magnetic field system 300 is connected to the electromagnet connecting platform 113 by screws and fixed to the hydrocyclone cavity 110.

[0072] When using a DC power supply as the electrical signal source for the electromagnet, connect the positive terminal of the DC power supply to terminal A307 of the electromagnet coil and the negative terminal to terminal B308 of the electromagnet coil. Similarly, connect the negative terminal of the DC power supply to terminal A307 of the electromagnet coil and the positive terminal to terminal B308 of the electromagnet coil of the opposite electromagnet. This generates a constant magnetic field in the flow field within the cylindrical section 115 of the cyclone separator. Connect a suitable resistor in series with the electromagnet to limit the current and prevent excessive current from damaging the electromagnet or the power supply. Connect a diode in parallel with the electromagnet leads to provide a path for the induced current in the coil when the power is off, preventing the generated back electromotive force from damaging other components in the circuit.

[0073] Connect the two leads of the electromagnet to the two wires (live wire and neutral wire) of the AC power supply. Generally, there is no need to distinguish the connection order of the live wire and the neutral wire. For the electromagnet, the connection order of the live wire and the neutral wire is reversed, which generates a changing magnetic field in the flow field within the cylindrical section 115 of the hydrocyclone.

[0074] Opposite electromagnet coils can be connected to the same DC power supply. When using a series connection, the negative terminal of the first coil is connected to the positive terminal of the next coil, and so on, until the positive terminal of the first coil is connected to the positive terminal of the power supply, and the negative terminal of the last coil is connected to the negative terminal. In this connection method, the current through each coil is the same, but the voltage across each coil is distributed according to factors such as the number of turns, and the total voltage is equal to the sum of the voltages of all coils.

[0075] When using a parallel connection, the positive terminals of all coils are connected together to the positive terminal of the power supply, and the negative terminals of all coils are connected together to the negative terminal of the power supply. In a parallel connection, the voltage across each coil is equal to the power supply voltage, and the total current is equal to the sum of the currents in each coil. When using a parallel connection, the power supply's output current capability must be sufficient to meet the current requirements of all coils.

[0076] For a DC-powered electromagnet, the current I of a long, straight solenoid electromagnet (when the solenoid length is much greater than its radius) can be calculated by the following formula:

[0077]

[0078] Where H is the magnetic field strength in A / m, and n is the number of turns. Ignoring the transient effects of the electromagnet's inductance, the voltage can be calculated using the following formula:

[0079]

[0080] The coil resistance R can be calculated using the following formula:

[0081]

[0082] ρ is the resistivity of the coil material (in Ωm), l is the total length of the coil (in m), and s is the cross-sectional area of ​​the coil wire (in m²). 2 ).

[0083] For an AC-powered electromagnet, the current I can be calculated using the following formula:

[0084]

[0085] Voltage can be calculated using the following formula:

[0086]

[0087] Where f is the AC frequency in Hz and L is the coil inductance in H.

[0088] The electric heating and insulation system includes an electric heating coil 400 and an insulation layer. The specific structure is as follows: Figure 1-3 As shown, the electric heating coil 400 is wound sequentially around the outside of the hydrocyclone inlet pipe 112, the cylindrical section 115 of the hydrocyclone, the large conical section 116 of the hydrocyclone, the small conical section 117 of the hydrocyclone, and the underflow pipe 118 of the hydrocyclone, and is covered with an insulation layer on the outside of the electric heating coil 400.

[0089] Connect the two terminals of the electric heating coil to the live wire and neutral wire of a single-phase power supply, respectively. Typically, the live wire is connected to one end of the heating coil, and the neutral wire to the other end. Install a switch and fuse on the live wire to cut off the power supply when necessary and prevent accidents.

[0090] The power P of the electric heating coil is calculated according to the following formula:

[0091] P = P1 + P2

[0092] Where P1 is the power required to heat the oil-water emulsion to the preset temperature, which is determined by the flow rate Q, the inlet temperature of the oil-water emulsion T1, and the preset temperature T2:

[0093] P1=cρQ(T2-T1)

[0094] P2 is determined by the thermal conductivity λ of the insulation layer, the thickness d of the insulation layer, the convective heat transfer coefficient h, the surface area A of the insulation layer, the ambient temperature T0, and the preset temperature T2.

[0095]

[0096] The sealing system includes gasket A500, gasket B510, and gasket C520. The specific structure is as follows: Figure 6 , 9 As shown in Figure 12, gaskets A500, B510, and C520 have the same inner and outer diameters. A groove is cut into the corresponding area on the inner side of gasket B510 to allow for electrode insertion, and a corresponding groove is cut into gasket C520 to allow for electrode sleeve insertion. The gaskets and flanges work together to form an effective seal between the rotating electric field system and the hydrocyclone system. The flange bolts are covered with an insulating layer to prevent short circuits caused by the electrodes or to charge the outer wall of the hydrocyclone, thus preventing electric shock.

The protection scope of the present invention is not limited to the above embodiments. Therefore, all equivalent changes or modifications made based on the principles and design ideas disclosed in the present invention are within the protection scope of the present invention.
