ABSTRACT

Aiming at the problem of blocked pipe in coal slurry pipeline transportation process, in the two phase of the project of 50MW unit in Shanxi Huangling coal gangue power generation company, the method of pressure wave slime pipeline blockage location is proposed based on wavelet transform, which is the analysis of the pipeline positioning principle based on the pressure wave method, the pressure wave is collected by the pressure sensor installed on the pipeline. Next, the abrupt change of the pressure signal is detected by the wavelet transform, which is integrated into the pressure wave method; Thus the pressure wave velocity and time difference are determined to realize the accurate location of the blockage point. The experimental platform of coal slurry pipeline transportation is built according to the proportion of 100:1, the simulation and experimental results show that the algorithm can be used for the location of the blockage fault in the viscous conveying pipeline system.
