Tower is a commonly used equipment in chemical processes, used for material separation, purification, reaction, and other operations. According to its structure and function, chemical equipment towers can be divided into the following categories: Column Category,Extraction Tower,Distillation Tower,Absorption Tower,Drying Tower Yangzhou Tongyang Chemical Equipment Co., Ltd. , https://www.tyceqt.com
1. Distillation Tower: used to separate different components in a mixture through distillation, commonly used in fields such as petrochemical and fine chemical industries.
2. Absorption Tower: used to absorb harmful components from gases into liquids, commonly used in the field of environmental protection.
3. Reaction tower: used for chemical reactions, commonly used in the production of chemicals, pharmaceuticals, and other fields.
4. Extraction tower: It is used to separate organic or inorganic compound substances in the mixture by solvent extraction, and is commonly used in petrochemical, fine chemical and other fields.
5. Drying Tower: used to remove moisture or other volatile components from liquid or solid substances, commonly used in fields such as food and medicine.
6. Crystallization tower: used to crystallize substances from a solution, commonly used in fields such as chemistry and medicine.
[ China Instrument Network Instrument R&D ] A few days ago, the world's first elevator warning and rescue vehicle independently developed by Hebei Prospecting and Optoelectronic Technology Co., Ltd., Qinhuangdao Economic and Technological Development Zone, passed the appraisal of the expert group and was formally put into production and market application.
China is the country with the largest number of elevators in the world. As of the end of 2017, China’s elevator installations exceeded 5 million, accounting for one-third of the world’s total. Every day, 110 cities across the country received more than 1,000 requests for help from the elevators, and the city’s elevator accidents. The death toll has increased year by year. Therefore, timely warning and rescue become very important.
The newly-developed world's first elevator rescue vehicle transforms elevator management from post-processing to early prevention, and comprehensively uses Internet of Things, big data, and cloud computing, and is a breakthrough in the design of elevator maintenance and early warning and rescue.
The elevator early-warning rescue vehicle contains 5 smart units, 18 precision inspection instruments and 31 emergency disposal tools. Through the space vector data acquisition technology and GPRS wireless communication, it can control the “health status†of urban elevators at the first time. The alarm rescue signal was immediately detected and the door was rescued at the first time.
The main functions of the elevator early-warning rescue vehicle are the comprehensive use of high-precision gyro acceleration sensing technology, high-definition video, Internet of Things, cloud computing, infrared imaging, life detection, environmental monitoring, and big data analysis management technologies, and data on elevator operation in the domain. Acquire, analyze, and process, intelligently predict and predict potential elevator failures, send elevator maintenance reminders, elevator annual inspection due reminders, emergency elevator emergency treatment, and emergency rescue for people trapped in elevator accidents.
The range of detection and warning of rescue vehicles can reach 5 kilometers, and the total number of monitoring elevators can reach 3000-8000 units. The rescue speed will be guaranteed within 15-30 minutes. In addition, the elevator early-warning rescue vehicles can run on the road and can do “health checkups†for all elevators equipped with “black boxes†in the city, analyze the operating parameters and current status of the elevators, intelligently analyze and troubleshoot hidden dangers, and Timely visits provide maintenance and rescue services.
At present, the elevator early-warning rescue vehicle has obtained one national invention patent and one utility model patent. Experts from the China Elevator Association, National Elevator Quality Supervision and Inspection Center and related research institutes spoke highly of the scientific and technological achievements. They believed that the project was innovative and the overall technology reached the international advanced level. It was the first in the world and filled the blanks at home and abroad. .
