This invention relates to the field of petrochemical technology, specifically to a method and system for preventing overheating in a C2 hydrogenation reactor. The method includes: S1, acquiring analytical data of the inlet and outlet of each section of the C2 hydrogenation reactor bed, as well as the inlet temperature; S2, determining alarm values ​​and interlock values ​​for each section of the C2 hydrogenation reactor bed based on the acquired inlet temperature and / or analytical data; S3, if an alarm is triggered based on the alarm value, confirming whether the operating parameters of each section of the C2 hydrogenation reactor bed are normal; S4, if an interlock is triggered based on the interlock value, adjusting the operating parameters of each section of the C2 hydrogenation reactor bed to reduce the inlet temperature of each section of the C2 hydrogenation reactor bed. Using this method, by determining the alarm values ​​and interlock values ​​for each section of the C2 hydrogenation reactor bed based on the acquired inlet temperature and / or analytical data, overheating in the C2 hydrogenation reactor can be effectively prevented in practical applications.

This invention provides a bisphenol A anion regeneration system, comprising an anion bed. The inlet pipes of the anion bed are connected to a demineralized water inlet pipe, a phenol inlet pipe, and a caustic soda inlet pipe. The anion bed is equipped with a top vent pipe and a bottom vent pipe, and a reverse flow pipe connects the inlet pipe and the bottom vent pipe. The upper inlet of the bottom vent pipe is higher than the upper surface of the anion bed. The advantages of this invention are: it extends the service life of the expensive anion catalyst, and through cyclic regeneration, avoids the huge cost of frequent catalyst replacement. The phenol solution used in the regeneration process can be recycled, and the waste alkali solution can be centrally treated or partially recovered, further reducing material consumption and waste disposal costs. Furthermore, during the regeneration operation, the material is introduced into the crystallization system through valve switching, avoiding shutdown of the entire production system, ensuring production continuity, and improving equipment utilization and overall economic efficiency.

This disclosure relates to a dust suppression method, apparatus, electronic device, and storage medium. The method includes: acquiring first location information of a first vehicle, and based on the first location information, acquiring nozzle position information of at least one spraying device installed on both sides of the road on which the first vehicle is traveling; determining, based on the first location information and the nozzle position information, whether there is an intersection between a first detection range of the first vehicle and the current spraying range of the at least one spraying device; and, if it is determined that there is an intersection between the first detection range and the current spraying range, controlling the at least one spraying device to open or close based on its operating state. This disclosure can prevent vehicles from stopping or traveling at low speeds due to the need to avoid obstacles, thus ensuring both dust suppression effectiveness and vehicle operating efficiency.

The invention relates to a U-shaped reinforcing mesh carrying and assembling production line, and relates to the technical field of reinforcing steel bar machining. The connecting frame is installed below the driving assembly, supporting plates which are symmetrically distributed are installed in the connecting frame, and the supporting plates can be connected between straight ribs on the two sides of a U-shaped reinforcing mesh in a lap joint mode so that stable movement of the U-shaped reinforcing mesh can be guaranteed. The driving assembly can control the moving direction of the connecting frame, then the moving direction of the U-shaped reinforcing mesh is controlled, automatic carrying of the U-shaped reinforcing mesh is achieved, the transportation time is greatly shortened, and the production efficiency is high. A bending part is arranged at the bottom of a supporting plate; an air cylinder is fixedly installed below the bottom beam, the top of the supporting plate is rotatably connected with the bottom beam, the air cylinder works to drive the supporting plate to rotate along the top of the supporting plate, then the bending part is controlled to stretch out and draw back, and stable lap joint and release of the U-shaped reinforcing mesh are guaranteed.

This application provides a path planning method and related equipment for dynamically connecting memory-based parking cruise and automatic parking. The method includes: acquiring a target memory path, which includes a cruise trajectory generated during the learning phase and a parking trajectory corresponding to the target parking space; generating a real-time driving trajectory during cruise replication based on the cruise trajectory, and determining the degree of overlap between the real-time driving trajectory and the cruise trajectory; based on the degree of overlap, determining, or re-generating, a target connection trajectory that connects with the parking trajectory and satisfies kinematic continuity constraints, from the real-time driving trajectory; and controlling the vehicle to enter the automatic parking phase from the cruise phase based on the target connection trajectory and the parking trajectory to complete the vehicle parking in the parking space. This application eliminates the physical dependence of pause actions or fixed switching points on the transition from the cruise phase to the automatic parking phase, avoids the parking process introduced by phase switching, and improves the continuity of parking task path connection and parking execution efficiency.
