Description

Technical Field

[0001] The present application relates to the technical field of phase separation monitoring, intelligent identification and precision control, and specifically discloses a cyhalofop-butyl intelligent phase separation monitoring and control system and method. Background Art

[0002] As a highly effective and selective herbicide, cyhalofop-butyl has played an important role in rice field weed control in recent years. In the traditional cyhalofop-butyl production process, the existing phase separation operation mainly relies on the operator's visual observation to determine the interface position between the aqueous phase and the organic phase. This manual judgment method has many disadvantages. First, due to the small difference in density between the aqueous phase and the organic phase, the interface is often not clear enough, and it is difficult for the operator to accurately determine the specific position of the dividing line. This imprecise interface identification directly leads to product loss or impurity residue in subsequent separation operations. Secondly, in the actual discharge process, the operator needs to manually control the opening and closing of the valve according to the visual judgment of the interface position. Due to the instability and reaction delay of manual operation, over-discharge or insufficient discharge often occurs, further exacerbating the problem of product loss and unstable quality. In addition, long periods of static waiting and frequent manual monitoring not only increase the production cycle, but also increase labor costs and reduce overall production efficiency. In complex chemical production environments, emulsification may occur, leading to abnormal situations where phase separation is difficult. Traditional manual monitoring methods are often unable to detect and warn of such problems in a timely manner, which can easily lead to the scrapping of batches of products and long-term occupancy of equipment.

[0003] During the cyanogen bromide washing process, residual bubbles from stirring will interfere with image clarity, and the interface recognition error in the cyanogen bromide system is large, which cannot meet the precision requirements of fine process. For real-time monitoring of the emulsion layer during phase separation, some factories use turbidity sensors to detect emulsification risks, but the thickness of the microemulsion layer produced during cyanogen bromide washing is very thin, and traditional turbidity sensors have poor resolution and cannot distinguish the particle size distribution of emulsion droplets at the micron level. In addition, if the microemulsion layer is not treated in time, the residual moisture in the organic phase after washing may exceed the standard, causing the entire batch of products to be downgraded. In long-term production practice, it has been found that the separation efficiency of cyanogen bromide washing is affected by thermodynamic parameters such as temperature and interfacial tension, and fluid mechanics conditions such as stirring shear rate and static pressure. However, the existing technology has not established a multi-parameter coordinated control model, which is prone to interface migration caused by temperature gradients and delayed detection of abnormal emulsification due to the lack of threshold association between stirring parameters and emulsification warning.

[0004] Therefore, in view of the above difficulties in the prior art, it is urgent to develop an intelligent phase separation monitoring and control system and method for cyhalofop-butyl. Summary of the Invention

The cyhalofop-butyl intelligent phase separation monitoring and control method according to claim 7, characterized in that: The water washing kettle is provided with a high temperature resistant transparent tilt monitoring mechanism, through which the state of the reactants in the water washing kettle is monitored; The high-temperature resistant transparent tilt monitoring mechanism comprises: a top perspective window (901), a high-temperature resistant tempered glass transparent cylinder (902), a precision depth scale line (903) and a cone bottom fixing point (904); the high-temperature resistant transparent tilt monitoring mechanism is arranged at the edge of the water washing kettle; the high-temperature resistant tempered glass transparent cylinder is a conical transparent cylinder and a precision depth scale line is arranged on the inclined surface of the cylinder wall for marking the depth of the reactant; the top perspective window is arranged at the top of the water washing kettle at the top of the high-temperature resistant tempered glass transparent cylinder for viewing the inside of the side wall of the conical transparent cylinder; the cone bottom fixing point fixes the conical bottom end of the high-temperature resistant tempered glass transparent cylinder to the bottom of the water washing kettle; the side wall of the conical transparent cylinder is transparent Display the status of the reactants in the water washing kettle from the top to the bottom; the side wall of the conical transparent cylinder is at an inclined angle to the camera lens; the top camera lens collects the image of the side wall of the conical transparent cylinder through the top perspective window, and the image of the side wall of the conical transparent cylinder forms a circular image. The closer the central circular image is to the central precision depth scale line, the deeper the depth is, and the interface image and liquid surface stratification image of the aqueous phase and the organic phase are obtained; the interface and liquid surface stratification depth of the aqueous phase and the organic phase are identified according to the precision depth scale line; the infrared spectrum sensor collects the infrared spectrum of the side oblique surface of the conical transparent cylinder through the top perspective window and performs infrared spectrum analysis to intelligently detect the concentration gradient of cyhalofop-butyl in the organic phase.

9. The cyhalofop-butyl intelligent phase separation monitoring and control method according to claim 6, characterized in that: S2 includes: The discharge of reactants at any depth is intelligently controlled by a depth lifting and discharging device; the depth lifting and discharging device comprises: an outer spiral lifting inner tube (1001), a lifting controller (1002), a telescopic rotating mechanism (1003) and a telescopic docking outer hose (1004); the rotation of the telescopic rotating mechanism is controlled by the lifting controller; the telescopic rotating mechanism is provided with an inner spiral; the outer spiral lifting inner tube is provided with an outer spiral; the inner spiral and the outer spiral engage with each other; when the telescopic rotating mechanism rotates, the inner spiral drives the outer spiral to rotate so that the outer spiral lifting inner tube is lifted and lowered, and the lower end of the outer spiral lifting inner tube is lifted and lowered to any depth, thereby discharging reactants at any depth; the upper end of the outer spiral lifting inner tube is sleeved in the telescopic docking outer hose; the upper layer reactants to be discharged, including the upper aqueous phase containing residual solvent, are led out to a recovery tank through the telescopic docking outer hose for use in the next batch of water washing; the discharge of reactants at any depth is intelligently controlled.
