Description

Technical Field

[0001] The utility model relates to the technical field of extraction phase separation, in particular to a phase separation tank interface control system. Background Art

[0002] When the desulfurization device or the extraction device is working, the phase separation tank interface control is a key step, which directly affects the quality of the product and the safety of production. The existing phase separation tank interface control technology mainly relies on manual observation and experience judgment. This method has the following technical problems:

[0003] 1. Reliance on manual experience. Traditional phase separation tank interface control is highly dependent on the operator's experience and vision. Workers need to regularly observe the oil-water interface in the phase separation tank to determine whether adjustments are needed. This method is not only inefficient, but also prone to misjudgment due to human subjectivity and fatigue.

[0004] 2. Accuracy issues: It is difficult to accurately determine the specific location of the interface by manual observation, especially when the interface is not obvious or the lighting conditions are poor, which may lead to inaccurate phase separation and affect product quality.

[0005] 3. Insufficient real-time performance. Manual observation cannot achieve real-time monitoring. Interface changes in the phase separation tank may occur rapidly in a short period of time, and the intervals between manual observations may result in missing the best adjustment opportunity.

[0006] 4. The labor intensity is high. Operators need to constantly patrol between the phase separation slots. The labor intensity is high, and in some harsh working environments, such as high temperature, toxic gases, etc., it poses a threat to the health of workers.

[0007] 5. Low production efficiency. Due to the limited efficiency of manual observation and adjustment, the production process may need to be frequently paused or slowed down for phase control, which directly affects the overall production efficiency.

[0041] like Figure 1-3 As shown, a phase-separation slot interface control system comprises:

[0042] At least one camera 1, the camera 1 is used to monitor the phase interface of the desulfurization device 6 in real time;

[0043] At least one interface meter 2, the interface meter 2 is used to measure and feedback the specific position of the interface of the extraction device 7;

[0044] A central processing unit 3, used to receive information from the camera 1 and the interface meter 2, and issue corresponding instructions according to a preset control logic;

[0045] At least one controller 4, the controller 4 is used to execute control actions of the desulfurization device 6 and the extraction device 7 according to the instructions of the central processing unit 3;

[0046] At least one control valve 5 is connected to the controller 4 , and the control valve 5 is used to adjust the phase separation interface height and phase separation speed of the desulfurization device 6 and the extraction device 7 .

[0047] Therefore, a camera 1 is provided around the desulfurization device 6, and the camera 1 is used to monitor the desulfurization device 6 and observe the interface conditions during phase separation. When it is found that the upper and lower layers of the interface are phase-separated, the central processing unit 3 collects this information and sends an instruction to the controller 4. The controller 4 closes the control valve 5 and stops the phase separation, thereby separating the upper and lower layers of liquid in the desulfurization device 6.

[0048] An interface meter 2 is provided on the extraction device 7. The interface meter 2 measures and feeds back the specific position of the interface of the extraction device 7. By detecting the change of the interface density and transmitting the change to the central processing unit 3, when the interface density is stable, phase separation begins; when there is an obvious difference in interface density between the upper and lower layers, especially when an obvious difference in interface density is detected at the bottom of the extraction device 7, the central processing unit 3 collects the information and sends a command to the controller 4. The controller 4 closes the control valve 5, stops the phase separation\ends the phase separation, thereby separating the upper and lower liquid layers in the extraction device 7.

[0049] In one embodiment, the central processing unit 3 includes an image processing element 31 for analyzing image data captured by the camera 1;

[0050] A data processing element 32, used to calculate the measurement data fed back by the interface meter 2;

[0051] A control logic element 33 is used to generate control instructions according to the image and data.

[0052] A user interface element 34 is used to display the real-time image monitored by the camera 1, the measurement data of the interface meter 2 and the status information of the system.

[0053] Specifically, the camera uses a high-definition industrial camera with automatic focus and optical zoom functions, which can adapt to different lighting conditions and distances and capture the phase interface image of the desulfurization device (for external display) in real time.

[0054] Specifically, the interface meter uses a high-precision laser displacement sensor or an ultrasonic level meter to measure and feedback the oil-water interface position of each extraction phase separation tank in the extraction device.

[0055] Specifically, the controller 4 generally refers to a programmable logic controller 4 (PLC) or a distributed control system (DCS). The controller 4 can receive signals from sensors and cameras 1 and control the device according to a preset program logic.

[0056] The control valve 5 can be a variety of valve types, such as a ball valve, butterfly valve, gate valve or diaphragm valve, etc., depending on the required flow control characteristics and the process conditions of the application. The control valve 5 can be automatic, driven by an electric or pneumatic actuator.

[0057] The data processing element 32 refers to the hardware within the central processing unit 3, such as a microprocessor or microcontroller, which is responsible for performing data processing tasks such as data acquisition, conversion and preliminary analysis; for example, using an industrial-grade data acquisition system (DAS) or an embedded computing module such as Raspberry Pi or Arduino.

[0059] The user interface element 34, which may be a touch screen interface, a computer display, or a dedicated control panel, is used to display system status, real-time images and measurement data, and to allow operator interaction and control.

[0060] Image processing element 31 refers to hardware integrated in the central processing unit 3 for performing image capture, processing and analysis tasks. It may include a dedicated image processing unit or a GPU (graphics processing unit). Image processing element 31, for example, uses high-performance image processing hardware, such as NVIDIA Jetson series modules or Intel RealSense depth camera modules.

[0061] In one embodiment, the extraction device 7 includes a plurality of extraction phase separation tanks 71 , and an interface meter 2 is disposed on a plurality of the extraction phase separation tanks 71 ; one end of the interface meter 2 is disposed at the middle and upper part of the extraction phase separation tank 71 , and the other end is disposed at the bottom of the extraction phase separation tank 71 .

[0062] A plurality of the extraction phase separation tanks 71 are provided with glass mirrors 72 for observing the extraction phase separation conditions, and a camera 1 is provided around the glass mirrors 72 .

[0063] At least one control valve 5 is provided on the discharge pipes of the plurality of extraction phase separation tanks 71 .

[0064] In one embodiment, the desulfurization device 6 includes a decalcification phase separation tank 61, a coarse desulfurization phase separation tank 62, and a fine desulfurization phase separation tank 63. The decalcification phase separation tank 61, the coarse desulfurization phase separation tank 62, and the fine desulfurization phase separation tank 63 are all provided with a glass sight glass 72 for observing the phase separation situation, and a camera 1 is provided around the glass sight glass 72.

[0065] At least one control valve 5 is provided on the discharge pipe of the decalcification phase separation tank 61;

[0066] At least one control valve 5 is provided on the discharge pipe of the coarse desulfurization phase separation tank 62; at least one control valve 5 is provided on the discharge pipe of the fine desulfurization phase separation tank 63. By providing a control valve 5 on the discharge pipe of each desulfurization phase separation tank, fine control of the entire desulfurization process is achieved.

[0067] The height of the rough desulfurization phase separation tank 62 is higher than that of the fine desulfurization phase separation tank 63. The height difference between the rough desulfurization phase separation tank and the fine desulfurization phase separation tank facilitates the transfer of materials.

[0068] The glass sight glass 72 is arranged on the discharge pipe of the desulfurization device 6 and the control valve 5 is arranged at the lower end of the glass sight glass 72. By arranging the glass sight glass 72 on the discharge pipe and arranging the control valve 5 at the lower end of the sight glass, the discharge situation of the phase separation tank can be intuitively monitored and accurately controlled. It provides a direct means for the operator to observe the discharge situation of the phase separation tank, which is convenient for real-time adjustment of the control valve 5 to maintain the stability of the phase separation interface.

[0069] like Figure 3 As shown, the specific process of the phase separation tank interface control system controlling the desulfurization device to perform phase separation is: the system first monitors the phase separation interface in real time through at least one camera set around the desulfurization device, and uses at least one interface meter to measure and feedback the specific position of the extraction device interface. After receiving this information, the central processing unit analyzes the image data through its built-in image processing element, the data processing element calculates the measurement data, and the control logic element generates a control instruction according to the analysis result. Subsequently, at least one controller operates at least one control valve connected to it according to the instruction of the central processing unit, adjusts the phase separation interface height and phase separation speed, and realizes automatic phase separation control. When the phase separation interface is clear and stable, the system automatically performs the phase separation operation; when the interface is transferred to the vicinity of the discharge port or the interface density changes significantly, the system will adjust or stop the phase separation operation in time to ensure the accuracy and efficiency of the phase separation process.

[0070] like Figure 2As shown, the specific process of the phase separation tank interface control system controlling the extraction device to perform phase separation is as follows: the system measures and feeds back the specific position of each extraction phase separation tank interface in the extraction device in real time through at least one interface meter, and observes the phase separation situation by using a camera arranged around the extraction phase separation tank. The central processing unit receives the measurement data of the interface meter and the image information of the camera, and after the image processing element analyzes the image data and the data processing element calculates the measurement data, the control logic element generates the corresponding control instructions. According to these instructions, at least one controller executes the control action and operates at least one control valve to adjust the phase separation interface height and phase separation speed of the extraction phase separation tank. When the interface density is stable and reaches the preset conditions, the system starts phase separation; when the interface density changes significantly or reaches the bottom of the extraction phase separation tank, the system stops the phase separation operation, thereby achieving precise liquid separation. The whole process reduces manual intervention, improves the automation level and response speed of phase separation control, and ensures the accuracy and efficiency of phase separation operation.

[0071] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
