Development Of The Material Level Recognition System Based On The Multi-temperature Sensors

In actual industrial field, the intermittent mixing heating device, such asreactor, flash autoclave, often used for gas-liquid phase separation process ofthe material. However, due to the characteristics of these devices withhigh-pressure high-temperature, it is difficult to directly measure the materiallevel inside. People have to take the observation mostly through theobservation hole artificially. Human observation is labor intensive, but notaccurate enough, and over time, the hole to observe may be blinded by thematerial which causes can not be observed. These reasons will have a directimpact on the planning and control, and threat the production safety. It is veryimportant to get to know how to solve these problems and find the best suitedto the production plant and field environment or a new detection method basedon the specific site conditions.This project is to undertake the Sinopec catalyst Oda branch who wantsto address the problem of technological innovation projects. The solution isusing multi-temperature sensors to collect temperature data of the space in theflash autoclave, achieve the online real-time identification of the level heightin the flash kettle by analyzing the data processing.The article describes the entire design in detail， especially in the techniques and principle in the project. At the same time, the entire project ismade a software for tool. Finally, the article prove that the software can meetthe basic requirements of the identification on the material level with thecompare of actual production of the observation data and the calculated dataobtained by software analysis in the process of normal feed.
