Exploration and research on acoustic imaging technology in gas leakage detection

Acoustic imaging technology is one of the cutting-edge technologies in the field of acoustic testing. There is a very broad market for applying acoustic imaging technology to gas leakage detection, but there are also situations where the detection distance is insufficient and the detection accuracy is insufficient, making it difficult to apply to scenarios with more stringent detection requirements. To improve the application ability of this technology in the detection field, in this paper, some technical improvement measures are described, the design idea of the Microphone array is mainly studied, and some progress in high sampling rate and detection frequency has been made, combined with equipment miniaturization design and comprehensive improvement of a software algorithm. Finally, according to actual measurement data, these technological upgrades have greatly improved the detection range and sensitivity of acoustic imaging technology in the detection process, making it particularly suitable for routine leak detection in large chemical plants.
