A pressure vessel leak detection system

Abstract

The invention discloses a pressure vessel leakage detection system, including a pressure sensor group provided with a GPS positioning module, a temperature sensor group provided with a GPS positioning module, a gas leakage detector, a central processing unit, a man-machine operation module, a physical model establishing module, a virtual actuator, a virtual sensor and a data processing module. The system performs analysis and evaluation on detected data through various data analysis methods, thereby greatly improving pressure measurement sensitivity and measurement accuracy, real-time observation of environmental conditions inside a pressure vessel is realized through establishment of a physical model, and each temperature sensor and each pressure sensor are equipped with the GPS positioning module, thereby further improving detection accuracy.

Description

technical field [0001] The invention relates to a leakage detection device, in particular to a pressure vessel leakage detection system. Background technique [0002] A pressure vessel is a closed container that bears a pressure load. Its main function is to store and transport high-pressure gas or liquid, or to provide a closed space for heat exchange and material reaction. It is widely used in petrochemical, pharmaceutical, metallurgy, aviation, etc. Aerospace, light industry and textile industries. [0003] Because pressure vessels often work in high-temperature and high-pressure environments, and the media they carry are mostly flammable, highly toxic or corrosive media, pressure vessels are special equipment with high risks. Once leakage, explosion and other accidents occur, it will cause casualties and heavy property losses. Through the analysis of the causes of pressure vessel safety accidents, the overpressure caused by operational errors or abnormal chemical react...
