Description

Technical Field

[0001] This invention relates to the field of crude oil dehydration technology, specifically to a dehydration device, method, and storage medium with dynamically adjustable electrode spacing. Background Technology

[0002] This section is intended to provide background or context for the embodiments set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] Crude oil extracted from wells generally contains a certain amount of water and needs to be dehydrated using an electrostatic dehydrator to separate the oil and water. Conventional electrostatic dehydrators typically have vertically or horizontally mounted electrodes. Currently, horizontally mounted electrodes have a fixed height. During the dehydration process, an electric field is created between high-voltage and low-voltage electrodes, causing water droplets in the water-containing crude oil to coalesce under the influence of the electric field, thus achieving dehydration.

[0004] In existing technologies, the distance between the high-voltage electrode and the low-voltage electrode is fixed, meaning the ratio of the electric field strength they form is constant. However, during crude oil dehydration, the lower part of the crude oil has a higher water content than the upper part, requiring a stronger electric field for the upper part and a weaker one for the lower part. Since the ratio of the electric field strength between the high-voltage and low-voltage electrodes is fixed, the dehydration efficiency gradually decreases during the dehydration process. This can even lead to the current exceeding the power supply's capacity, causing a power supply failure and a "reversed electric field," thus affecting the dehydration effect. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a dehydration device, method, and storage medium with dynamically adjustable electrode spacing.

[0048] The present disclosure will be further described below with reference to the embodiments shown in the accompanying drawings.

[0049] This application discloses a dehydration device with dynamically adjustable electrode spacing, such as... Figure 1 As shown, the device includes a container 1, a first electrode 5, a second electrode 2, a movable electrode 3, a spacing adjustment mechanism 10, a controller 12, and a power supply 13. The first electrode 5 and the second electrode 2 are fixed sequentially inside the container 1 from top to bottom. The movable electrode 3 is located between the first and second electrodes and is moved by the spacing adjustment mechanism 10. When the movable electrode 3 moves closer to the first electrode 5, the spacing between the movable electrode 3 and the first electrode 5 decreases, while simultaneously increasing the spacing between the movable electrode 3 and the second electrode 2. The controller 12 is connected to the spacing adjustment mechanism 10 to control the spacing adjustment mechanism 10. The power supply 13 is connected to the container 1, the first and second electrodes, and the movable electrode 3 to provide electrical energy for the electro-dehydration process.

[0050] In some embodiments, the controller 12 and the power supply 13 are integrated in the control cabinet 11, and the controller 12 is connected to the power supply 13 to obtain electrical energy from the power supply 13 for use. The control cabinet 11 is an explosion-proof cabinet, possessing explosion-proof functionality to improve safety during use.

[0051] In some embodiments, container 1 is used to contain crude oil. An inlet pipe is connected to container 1, allowing water-containing crude oil to flow into container 1 through the inlet pipe and undergo dehydration within container 1, resulting in the separated wastewater accumulating at the bottom of container 1. Furthermore, container 1 is a horizontal cylindrical container with a circular cross-section to facilitate the flow of water-containing crude oil within it.

[0052] In some embodiments, container 1 is electrically connected to the low-voltage end of power supply 13 to establish an electric field within container 1 for electro-dehydration. The high-voltage end of power supply 13 is connected to movable electrode 3, and the two output terminals of the low-voltage end are electrically connected to the first electrode 5 and container 1, respectively. The first electrode 5 is fixed inside container 1 by an insulating hanger 6 to prevent electrical connection between the first electrode 5 and container 1, allowing power supply 13 to directly output current to the first electrode 5. The second electrode 2 is electrically connected to container 1, allowing electrical connection between the container 1 and the low-voltage end of power supply 13. That is, after power supply 13 outputs current to container 1, the current is introduced into the second electrode 2 through container 1, causing the second electrode 2 to generate an electric field for dehydration. The second electrode 2 is located at the bottom of container 1 and is immersed in liquid. Introducing the low-voltage current of power supply 13 into the second electrode 2 through container 1 avoids wire connections, thereby preventing leakage and short circuits and improving the stability of electro-dehydration.

[0053] In some embodiments, the insulating hanger 6 is an insulating rod made of insulating material, such as rubber, plastic, glass, mica, etc. One end of the insulating rod is fixed to the first electrode 5, and the other end is fixed to the inner wall of the container 1, so as to suspend the first electrode 5 inside the container 1.

[0054] In some embodiments, the spacing adjustment mechanism 10 is connected to the power supply 13 to drive it by outputting electrical energy through the power supply 13. Specifically, the spacing adjustment mechanism 10 includes a motor and a lead screw transmission structure connected to the motor. The motor is connected to and controlled by the controller 12 to execute the spacing adjustment signal output by the controller 12. The lead screw transmission structure can perform linear motion under the drive of the motor, and the end of the lead screw transmission structure away from the motor is connected to the movable electrode 3 to drive the movable electrode 3 to move. Thus, the rotational motion is converted into vertical linear motion through the lead screw transmission structure to drive the movable electrode 3 to rise and fall, thereby realizing the spacing adjustment between the movable electrode 3 and the first and second electrodes.

[0055] In other embodiments, the spacing adjustment mechanism 10 may also be a servo electric linear cylinder, or other mechanism that drives the movable electrode 3 to move up and down linearly by electricity, thereby converting electrical energy into power to drive the movable electrode 3 to move up and down, so that the distance the movable electrode 3 is driven by the spacing adjustment mechanism 10 can be controlled by the controller 12.

[0056] In some embodiments, the movable electrode 3 is connected to the spacing adjustment mechanism 10 via an insulating connector 4. The insulating connector 4 provides electrical isolation between the spacing adjustment mechanism 10 and the movable electrode 3, keeps the movable electrode 3 in a horizontal state, prevents energization between the movable electrode 3 and the spacing adjustment mechanism 10, maintains a stable electric field, and ensures that the movable electrode 3 remains horizontal after the spacing adjustment mechanism 10 drives it to move. Both the first electrode 5 and the second electrode 2 are horizontal and parallel to each other, ensuring that the movable electrode 3 remains parallel to the first and second electrodes during its movement, thus guaranteeing the uniformity of the electric field intensity change.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, multiple insulating connectors 4 are provided and symmetrically distributed on the movable electrode 3 to keep the movable electrode 3 in a horizontal state. In this embodiment, there are four insulating connectors 4. The four insulating connectors 4 can be connected to the same spacing adjustment mechanism 10 at the same time for linkage, or they can be connected to multiple spacing adjustment mechanisms 10 respectively. As long as they can synchronously drive the multiple insulating connectors 4 to rise and fall, and the rising and falling distances are consistent, it can be ensured that the movable electrode 3 is always in a horizontal state when moving.

[0058] In some embodiments, when the active electrode 3 is small in size and light in weight, only one insulating connector 4 can be used for connection, making the overall structure simple and easy to install and use.

[0059] In some embodiments, specifically, the insulating connector 4 includes a connecting rod 9 and an insulating hanger 41. One end of the insulating hanger 41 is connected to the movable electrode 3, and the other end is connected to the connecting rod 9. The insulating hanger 41 has the same structure as the insulating hanger 6 of the first electrode 5, and both are made of insulating material. The end of the connecting rod 9 away from the insulating hanger 41 moves through the container 1 and is connected to the spacing adjustment mechanism 10.

[0060] In some embodiments, the dehydration device further includes a plurality of height detection mechanisms 8, each corresponding to one of the insulating connectors 4. The plurality of height detection mechanisms 8 are used to detect the height of the plurality of insulating connectors 4 and feed the results back to the controller 12 to ensure that the heights of the plurality of insulating connectors 4 are consistent. The height detection mechanism 8 includes a height indicator sensor, which can monitor changes in the height of the insulating connectors 4, so that the controller 12 can control the raising and lowering of the movable electrode 3 and ensure that the movable electrode 3 is in a horizontal state.

[0061] In some embodiments, to facilitate the movement of the insulating connector 4 on the container 1, a sealing structure 7 is provided on the container 1; the end of the insulating connector 4 away from the movable electrode 3 moves through the sealing structure 7 and is connected to the spacing adjustment mechanism 10. Specifically, the sealing structure 7 includes a sealing hole opened on the container 1 and an O-ring fitted inside the sealing hole. The insulating connector 4 moves through the O-ring, thereby allowing the insulating connector 4 to move while achieving a seal to prevent leakage of high-pressure fluid inside the container 1.

[0062] In some embodiments, to facilitate accurate control of the adjustment of the spacing between the electrodes, a first current sensor 14 for real-time detection of the output current of the power supply 13 is connected between the movable electrode 3 and the power supply 13; a second current sensor 15 for real-time detection of the current between the movable electrode 3 and the first electrode 5 is connected between the first electrode 5 and the power supply 13; both the first and second current sensors are connected to the controller 12 to feed back the current signal to the controller 12; the controller 12 determines the state of the two electric fields based on the current signal, and outputs a spacing adjustment signal or a voltage adjustment signal according to the state of the electric fields.

[0063] In some embodiments, the controller 12 is used to calculate the current between the active electrode 3 and the second electrode 2 based on the first and second current sensors, so as to analyze whether there is a risk of electric field breakdown in the state of the two electric fields based on the current between the active electrode 3 and the first and second electrodes respectively.

[0064] Specifically, the current between the movable electrode 3 and the first electrode 5 is the current value fed back by the second current sensor 15. When calculating the current between the movable electrode 3 and the second electrode 2, the current between the movable electrode 3 and the second electrode 2 can be obtained by subtracting the current value fed back by the second current sensor 15 from the current value fed back by the first current sensor 14. Based on the current situation, the electric field dehydration state can be analyzed, and the risk of electric field breakdown between the upper and lower electric fields can be judged. If the shunt current is relatively small, it indicates that there is potential to increase the electric field strength, and the electrode spacing can be reduced. Conversely, the electrode spacing needs to be increased. When a risk occurs, on the one hand, the output voltage of the power supply 13 is controlled, and on the other hand, the position of the movable electrode 3 is adjusted to prevent a significant increase in the current between the movable electrode 3 and either the first or second electrode, thus preventing the problem of "reverse electric field" from occurring. This ensures that the first and second electrodes maintain a high voltage, allowing both the upper and lower electric fields to function effectively, thereby achieving optimal dehydration.

[0065] In some embodiments, the controller 12 employs a PID control method to automatically tune parameters, thereby achieving automated control and regulation of the active electrode 3 and the output voltage of the power supply 13, improving the degree of automation. Specifically, the control target can be set to ensure that the current between the first electrode 5 and the active electrode 3 is equal to the current between the second electrode 2 and the active electrode 3, and the parameters can be automatically tuned accordingly. Alternatively, the ratio of the two currents can be set as the control target. When the ratio is 1:1, the two currents are equal, thus ensuring that dehydration is in the optimal state.

[0066] In some embodiments, the controller 12 adjusts the voltage of the power supply 13 by using a certain value of the total current as the voltage output adjustment target of the power supply 13. For example, when the total current detected by the first current sensor 14 is greater than one-third of the rated current, the voltage output value of the power supply 13 is reduced to achieve automatic parameter setting and automatic control of the voltage output of the power supply 13.

[0067] The dehydration device with dynamic electrode spacing adjustment provided in this embodiment can monitor the dehydration situation in real time and adjust the position of the movable electrode 3 according to the changes in the dehydration state to dynamically adjust the spacing between the movable electrode 3 and the first and second electrodes, thereby adjusting the intensity of the two electric fields. Moreover, by simply controlling the movable electrode 3 to move in one direction, the spacing between the movable electrode 3 and the first and second electrodes can be adjusted simultaneously, which has synchronicity and timeliness. This allows the electric field to be dynamically adjusted even when the water content of the crude oil in the upper and lower parts of the container 1 changes as dehydration progresses, providing a reasonable electric field intensity for dehydration operations, so that dehydration is always in the optimal state and improving the dehydration effect of the entire electric field.

[0068] At least some embodiments of this disclosure also provide a dehydration method with dynamically adjustable electrode spacing, such as... Figure 3 As shown, a dehydration method for controlling the dehydration device in any of the foregoing embodiments includes: acquiring the total output current of the power supply and the first component current between the movable electrode and the first electrode; calculating the second component current between the movable electrode and the second electrode based on the total output current and the first component current; determining the state of the two electric fields between the movable electrode and the first and second electrodes based on the first and second component currents; and outputting a spacing adjustment signal based on the state of the two electric fields to drive the movable electrode to move and adjust the spacing using a spacing adjustment mechanism. This method enables real-time dynamic adjustment of the spacing between the electrodes according to the electric field conditions, ensuring that the spacing between the movable electrode and the first and second electrodes is in the optimal position, maintaining the best electro-dehydration state, and improving the electro-dehydration effect.

[0069] This disclosure provides at least one embodiment of a dehydration method with dynamic adjustment of electrode spacing. This dehydration method can be implemented in the form of software, hardware, firmware, or any combination thereof. It is loaded and executed by a processor in a device such as a mobile phone, tablet computer, laptop computer, desktop computer, or network server, thereby realizing real-time dynamic adjustment of the spacing between each electrode according to the electric field conditions, ensuring that the distance between the active electrode and the first and second electrodes is in the optimal position, always maintaining the best electro-dehydration state, and improving the electro-dehydration effect.

[0070] The following is for reference. Figure 3 As shown, a dehydration method for dynamically adjusting the electrode spacing provided in at least one embodiment of the present disclosure is described, the control method including steps S1 to S4.

[0071] S1. Obtain the total output current of the power supply and the first component current between the active electrode and the first electrode;

[0072] S2. Calculate the second component current between the active electrode and the second electrode based on the total output current and the first component current;

[0073] In some embodiments, before performing step S2, such as Figure 4 As shown, the dehydration method also includes the following steps:

[0074] S201, Preset total output current value of the power supply;

[0075] S202. Compare the total output current with the rated total output current value to determine whether the power supply output voltage needs to be adjusted.

[0076] S203. If yes, output a voltage adjustment signal to adjust the output voltage of the power supply, and cycle back to step S1 until the output voltage of the power supply no longer needs to be adjusted.

[0077] In some embodiments, step S202 includes: when the total output current is greater than one-third of the rated total current value, determining that the output voltage of the power supply needs to be adjusted, that is, the voltage output value of the power supply needs to be reduced.

[0078] In some embodiments, step S2 includes: subtracting the first current from the total output current to calculate the second current between the dehydration method and the second low-voltage electrode.

[0079] S3. Determine the state of the two electric fields of the active electrode and the first and second electrodes based on the first and second currents.

[0080] S4. Output a spacing adjustment signal according to the state of the two electric fields, so that the spacing adjustment mechanism drives the dehydration method to move to adjust the spacing.

[0081] In some embodiments, step S4, such as Figure 5 As shown, it includes:

[0082] S41. Determine whether the two electric fields have a risk of electric field breakdown based on the state of the two electric fields.

[0083] S42. If so, with the goal of controlling the ratio of the first current to the second current to be equal to a preset value, determine the adjustment value of the distance between the active electrode and the first electrode and the second electrode.

[0084] S43. Output a spacing adjustment signal according to the spacing adjustment value.

[0085] In some embodiments, in step S42, when the preset value of the ratio of the first current to the second current is 1:1, that is, with the goal of controlling the first current to be equal to the second current, the adjustment value of the distance between the active electrode and the first and second electrodes is determined. Specifically, the control target can be selected as the first current equal to the capacitor current, or the first current to the second current being in other preset ratios, depending on the water content of the crude oil, so that the dehydration is in the optimal state.

[0086] In some embodiments, the control method operates in real time throughout the electro-dehydration process until electro-dehydration is completed, thereby dynamically adjusting the distance between the active electrode and the first and second electrodes according to the real-time status, and improving the electro-dehydration effect.
