Thread Content

Chemical equipment has developed greatly in the past ten years. Praise for China's prosperity and strength in the prosperous age. It will be more lively and exciting with everyone's participation. You are welcome to participate in the forum for more exchanges and discussions. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * In March 2023, the "Online Monitoring System for Safe Operation of Hazardous Chemicals Floating Roof Storage Tanks (Major Hazardous Sources)" project of the Hebei Provincial Institute of Emergency Management Sciences passed the expert acceptance organized by the Hebei Provincial Department of Science and Technology. The expert group believes that this project can achieve all-round, fully automatic real-time measurement and further ensure the safe operation of equipment. 　　It is understood that the drift measurement system consists of 8 explosion-proof laser rangefinders and industrial control measurement software. The machine vision component is fixedly installed on the floating roof of the floating roof storage tank and moves with the floating roof of the floating roof storage tank. The visual sensor collects the image of the laser target disk in real time. Through image analysis, the amount of rotation of the floating roof of the floating roof storage tank during operation can be obtained, and real-time online intelligent monitoring of the operating parameters of major hazard sources (storage tanks and gas tanks) can be carried out to achieve rapid perception of safety risks, real-time monitoring, advance warning, and coordinated handling of emergency situations. 　　The acceptance results show that the system can achieve all-round, fully automatic real-time measurement of storage tanks, completely eliminating manual entry into high-risk environments for on-site measurements, and achieving unmanned on-site operations. By establishing mathematical models and big data calculations, it has achieved accurate measurement of the maximum values ​​of inclination, drift and location, improving the level of automated monitoring in the operation of major hazardous sources. When the monitoring parameter index exceeds the limit value of process requirements during the operation of major dangerous sources, the system will issue an alarm in real time and activate the corresponding interlocking mechanism, providing safety guarantee for the operation of major dangerous sources. 　　According to Li Chaobo, director of the Technology Transfer Center of the Hebei Provincial Institute of Emergency Management Sciences, there are many major hazard sources similar to floating roof storage tanks in industrial enterprises, and the monitoring levels are uneven. This project fills the gap in the field of online real-time monitoring of major hazard sources in Hebei Province. While standardizing the content and methods of the online monitoring system for major hazard sources, it also provides software and hardware equipment for online monitoring systems for floating roof storage tanks and gas cabinets. It is a new product for online monitoring of major hazard sources for industrial enterprises. This project has driven the technological progress of online monitoring systems for major hazard sources in industrial enterprises, provided a powerful means for relevant enterprises to improve their safety risk management and control levels, and improved their capabilities in rapid perception, real-time monitoring, advance warning, joint disposal and system assessment of safety risks.
