| 针对现有工业领域存在的管道结垢清理成本高、除垢效果不易观察等问题，设计了一种基于红外测温的超声波管道除垢检测系统。首先，设计了应用于管道除垢的超声波电源，其工作频率为21.5kHz，电源最大输出功率500W，并使用YM32A红外阵列传感器检测管道表面温度变化。其次，基于COMSOL Multiphysics仿真软件，结合流体温度、热阻分布和管道形状等，分析了管道及其污垢的热传输特性，建立了管道表面温度和管道内垢层厚度的对应关系。最后，通过模拟产线环境的实验，验证了基于红外传感器检测管道表面温度的在线管道除垢系统的性能。系统对除垢厚度的判断精度达到至少1.2mm，实现平均89.7%的除垢率，平均缩短22%的工作时间。 |

| Aiming at the existing problems in the industrial field, such as the high cost of pipeline scale cleaning and the effect of scale is not easy to observe, an ultrasonic pipe descaling detection system based on infrared temperature measurement is designed. The ultrasonic power used for pipe descaling was designed with an operating frequency of 21.5kHz and a maximum output power of 500W. The YM32A infrared array sensor was employed to detect the temperature changes on the pipe surface. Using COMSOL Multiphysics simulation software, the thermal transfer characteristics of the pipeline and its fouling were analyzed by combining the fluid temperature, thermal resistance distribution and the shape of the pipeline, and the corresponding relationship between the surface temperature of the pipeline and the thickness of the fouling layer inside the pipeline was established. The performance of the on-line pipeline descaling system, based on infrared sensors to detect the pipeline surface temperature, was finally verified through experiments simulating the production line environment. The system measures the descaling thickness to an accuracy of at least 1.2mm, achieving an average descaling rate of 89.7% and an average reduction in working time of 22%. |
