Description

Technical Field

[0001] This application relates to the field of intelligent identification and precision control technology for phase separation monitoring, and specifically discloses an intelligent phase separation monitoring and control system and method for cyhalofop-butyl. Background Technology

[0002] Cyhalofop-butyl, as a highly effective and selective herbicide, has played a crucial role in weed control in rice paddies in recent years. In the traditional cyhalofop-butyl production process, existing phase separation operations primarily rely on visual observation by operators to determine the interface between the aqueous and organic phases. This manual method has several drawbacks. First, due to the small density difference between the aqueous and organic phases, the interface is often unclear, making it difficult for operators to accurately determine the specific location of the boundary. This inaccurate interface identification directly leads to product loss or impurity residue in subsequent separation operations. Second, during actual dispensing, operators need to manually control the opening and closing of valves based on the visually determined interface position. Due to the instability and reaction delay of manual operation, over-dispensing or under-dispensing often occurs, further exacerbating product loss and quality instability. Furthermore, prolonged settling and frequent manual monitoring not only increase the production cycle but also raise labor costs and reduce overall production efficiency. In complex chemical production environments, emulsification may occur, leading to difficulties in phase separation. Traditional manual monitoring methods often fail to detect and warn of such problems in a timely manner, which can easily result in the scrapping of batches of products and prolonged equipment occupation.

[0003] During the washing process of cyhalofop-butyl, residual bubbles from stirring can interfere with image clarity, resulting in significant interface recognition errors in the cyhalofop-butyl system, which cannot meet the precision requirements of fine processing. Regarding real-time monitoring of the emulsion layer during phase separation, some factories use turbidity sensors to detect emulsification risks. However, the microemulsion layer generated during cyhalofop-butyl washing is extremely thin, and traditional turbidity sensors have poor resolution and cannot distinguish the micron-sized distribution of emulsion droplets. Furthermore, failure to promptly address the microemulsion layer can lead to excessive residual moisture in the organic phase after washing, resulting in downgrading of the entire batch of products. Long-term production practice has revealed that the separation efficiency of cyhalofop-butyl washing is affected by thermodynamic parameters such as temperature and interfacial tension, as well as fluid dynamic conditions such as stirring shear rate and static pressure. However, existing technologies lack a multi-parameter collaborative control model, making them prone to interfacial migration due to temperature gradients and delayed detection of abnormal emulsification due to the lack of threshold correlation between stirring parameters and emulsification warnings.

[0004] Therefore, in view of the problems existing in the above-mentioned technologies, there is an urgent need to develop an intelligent phase separation monitoring and control system and method for cyhalofop-butyl. Summary of the Invention

[0005] This application provides a smart phase separation monitoring and control system and method for cyhalofop-butyl to solve the problems mentioned in the background art.

[0006] This application discloses a smart phase separation monitoring and control system for cyhalofop-butyl, comprising: a visual monitoring unit, a control unit, an execution unit, and an early warning unit;

[0007] The visual monitoring unit is used to acquire real-time images of liquid surface stratification and detect the concentration gradient of cyhalofop-butyl.

[0008] The control unit sets emission thresholds based on visual data;

[0009] The execution unit is used for automatic discharge of stratified liquid;

[0014] Furthermore, the turbidity sensor detection threshold of the early warning unit is 50 NTU, and the AI ​​emulsification analysis module identifies and analyzes the interface ambiguity in real time. When the interface ambiguity is >30%, a three-level intervention measure is triggered. The identification and analysis of interface ambiguity includes: expressing the interface ambiguity as a percentage. The more blurred the interface, the higher the percentage, indicating a higher degree of interface ambiguity, a lower clarity of the phase separation interface, and a less complete phase separation. The more clear the interface, the lower the percentage, indicating a lower degree of interface ambiguity, a higher clarity of the phase separation interface, and a more complete phase separation. Starting from a percentage of 0%, the percentage increases sequentially to 100%, with the corresponding interface boundary line width gradient value increasing progressively.

[0015] A method for intelligent phase separation monitoring and control of cyhalofop-butyl includes:

[0016] S1. Water washing and setting and interface monitoring: Implement a first water wash at 50℃ → a second water wash at 60℃ → a third water wash at 60℃.

[0017] S2. Automatic discharge of layered liquid: Three-dimensional liquid surface modeling is performed to identify the phase interface. After the first water wash and settling, the lower layer containing inorganic salt water phase is discharged. After the second water wash and settling, the upper layer aqueous phase is discharged. After the third water wash and settling, the lower layer organic phase is vacuum-inhaled into the vacuum dehydration kettle.

[0018] S3. Emulsification Risk Identification: The turbidity sensor in the early warning unit monitors turbidity, and the AI ​​emulsification analysis module identifies and analyzes the ambiguity of the interface in real time.

[0019] Furthermore, if turbidity > 50 NTU or interface ambiguity > 30% is detected in step S3, it is determined to be an emulsification risk. The early warning unit will immediately sound an alarm and perform the following operations: extend the settling time and retest the interface clarity every 10 minutes; start the steam heating of the jacket of the water washing kettle to 70°C to accelerate phase separation; record the abnormal data and notify the operator to check.

[0020] Furthermore, the washing vessel is equipped with a high-temperature resistant transparent tilt angle monitoring mechanism to monitor the state of the reactants inside the vessel. This mechanism includes: a top viewing window, a high-temperature resistant tempered glass transparent cylinder, precision depth scale lines, and a cone-shaped fixing point. The monitoring mechanism is located along the edge of the washing vessel. The high-temperature resistant tempered glass transparent cylinder is cone-shaped and has precision depth scale lines on its inclined surface to indicate the depth of the reactants. The top viewing window is located at the top of the high-temperature resistant tempered glass transparent cylinder, allowing visualization of the interior of the cone-shaped cylinder's sidewall. The cone-shaped fixing point secures the cone-shaped bottom of the high-temperature resistant tempered glass transparent cylinder to the water... The bottom of the washing vessel; the transparent sidewall of the conical transparent cylinder displays the state of the reactants from top to bottom inside the washing vessel; the sidewall of the conical transparent cylinder is at an angle to the camera lens; the top camera lens acquires images of the sidewall of the conical transparent cylinder through the top viewing window, forming a circular image. The closer the center of the circular image is to the center, the deeper the depth is indicated by the precision depth scale line, thus acquiring the interface image between the aqueous phase and the organic phase and the liquid surface layer image; the interface and liquid surface layer depth between the aqueous phase and the organic phase are identified according to the precision depth scale line; the infrared spectroscopy sensor acquires the infrared spectrum of the inclined side of the conical transparent cylinder through the top viewing window and performs infrared spectral analysis to intelligently detect the concentration gradient of cyhalofop-butyl in the organic phase.

[0021] Furthermore, S2 includes: intelligent control of the discharge of reactants at any depth via a depth lifting and discharging device; the depth lifting and discharging device includes: an outer spiral lifting inner tube, a lifting controller, a telescopic rotation mechanism, and a telescopic docking outer hose; the lifting controller controls the rotation of the telescopic rotation mechanism; the telescopic rotation mechanism is provided with an inner spiral; the outer spiral lifting inner tube is provided with an outer spiral; the inner and outer spirals interlock; when the telescopic rotation mechanism rotates, the inner spiral drives the outer spiral to rotate, causing the outer spiral lifting inner tube to rise and fall, with the lower end of the outer spiral lifting inner tube rising and falling to any depth, discharging reactants at any depth; the upper end of the outer spiral lifting inner tube is sleeved inside the telescopic docking outer hose; through the telescopic docking outer hose, the upper reactants to be discharged, including the upper aqueous phase containing residual solvent, are exported to a recovery tank for use in the next batch of primary water washing; intelligent control of the discharge of reactants at any depth.

[0023] 1. This application utilizes 3D modeling and multispectral fusion technology to achieve precise phase interface positioning under high-temperature steam interference. Compared to traditional manual visual errors, the system improves interface recognition accuracy and, combined with dynamic edge recognition, effectively solves the problem of low grayscale contrast caused by the equal density of the organic and aqueous phases in cyhalofop-butyl.

[0024] 2. A turbidity sensor (threshold 50 NTU) and an AI emulsification analysis module are used to monitor the interface ambiguity in real time. When a risk is detected, a three-level intervention is triggered. The three-level intervention includes: Level 1 intervention: extending the settling time and retesting the interface; Level 2 intervention: heating to 70°C to accelerate phase separation; Level 3 intervention: audible and visual alarm and simultaneous recording of abnormal data.

[0025] 3. Through vacuum-temperature coupling control (a 10°C increase in temperature corresponds to a 0.01MPa decrease in vacuum during the dehydration stage) and gradient distillation management (heating to 90°C at 5°C / min), the moisture content can be recovered in stages (>50%, 2-50%, <2%).

[0026] 4. The system integrates an electric regulating valve and a vacuum dehydration pipeline (-0.08MPa) to automatically discharge the aqueous / organic phase in stages, shortening the time of a single water washing operation.

[0027] 5. Based on a 3D liquid surface point cloud model and anomaly data recording function, full-cycle data traceability for production batches is achieved. By analyzing historical data and interface judgment, water washing and settling time can be saved; through intelligent sensing, multi-parameter collaborative control, and data closed-loop management, the problems of low precision, high emulsification risk, and high energy consumption in cyhalofop-butyl phase separation are overcome, significantly improving product quality and production efficiency, and making it suitable for large-scale industrial production.

The high-temperature resistant transparent tilt angle monitoring mechanism includes: a top viewing window (901), a high-temperature resistant tempered glass transparent cylinder (902), precision depth scale lines (903), and a cone-shaped bottom fixing point (904). The high-temperature resistant transparent tilt angle monitoring mechanism is located on the edge of the washing vessel. The high-temperature resistant tempered glass transparent cylinder is a cone-shaped transparent cylinder with precision depth scale lines on its inclined surface to indicate the depth of the reactants. The top viewing window is located at the top of the high-temperature resistant tempered glass transparent cylinder, at the top of the washing vessel, to allow viewing of the interior of the cone-shaped transparent cylinder's side wall. The cone-shaped bottom fixing point secures the cone-shaped transparent cylinder to the water. The bottom of the cone-shaped transparent cylinder is fixed to the bottom of the washing vessel; the side wall of the cone-shaped transparent cylinder is transparent, showing the state of the reactants from top to bottom inside the washing vessel; the side wall of the cone-shaped transparent cylinder is at an angle to the camera lens; the top camera lens acquires the image of the side wall of the cone-shaped transparent cylinder through the top viewing window, and the image of the side wall of the cone-shaped transparent cylinder forms a circular image. The closer the center of the circular image is to the center, the deeper the depth is marked by the precision depth scale line, thus acquiring the interface image of the aqueous phase and the organic phase and the liquid surface layer image; the interface and liquid surface layer depth of the aqueous phase and the organic phase are identified according to the precision depth scale line; the infrared spectroscopy sensor acquires the infrared spectrum of the inclined side of the cone-shaped transparent cylinder through the top viewing window and performs infrared spectral analysis to intelligently detect the concentration gradient of cyhalofop-butyl in the organic phase.

5. The intelligent phase separation monitoring and control method for cyhalofop-butyl according to claim 4, characterized in that, S2 includes: The deep lifting and discharging device intelligently controls the discharge of reactants at any depth. The device includes an outer spiral-patterned lifting inner tube (1001), a lifting controller (1002), a telescopic rotation mechanism (1003), and a telescopic docking outer hose (1004). The lifting controller controls the rotation of the telescopic rotation mechanism. The telescopic rotation mechanism has an inner spiral pattern. The outer spiral-patterned lifting inner tube has an outer spiral pattern. The inner and outer spiral patterns interlock. When the telescopic rotation mechanism rotates, the inner spiral pattern drives the outer spiral pattern to rotate, causing the outer spiral-patterned lifting inner tube to rise and fall. The lower end of the outer spiral-patterned lifting inner tube rises and falls to any depth, discharging reactants at any depth. The upper end of the outer spiral-patterned lifting inner tube is connected to the telescopic docking outer hose. Through the telescopic docking outer hose, the upper reactants to be discharged, including the upper aqueous phase containing residual solvent, are discharged to a recovery tank for use in the next batch of primary water washing. The device intelligently controls the discharge of reactants at any depth.
