The invention discloses a refined deslagging and drainage
system, and relates to the technical field of operation and maintenance of
coal mine gas pipelines. The
system comprises a multi-
sensor fusion sensing module, a dynamic
adaptive control module, a graded deslagging execution module, an anti-blocking self-cleaning module, a distributed fault self-diagnosis module and a modular extensible control framework. The multi-
sensor fusion sensing module collects working condition data such as
slag particle concentration and pressure in a pipeline, the dynamic self-adaption control module judges working conditions and blocking risks in a grading mode and outputs accurate instructions, and the grading type
slag discharging execution module adapts to different working conditions through main and auxiliary pump grading operation and
energy recovery. The anti-blocking self-cleaning module cooperates with forward and reverse rotation of a pump body to prevent blocking through high-pressure pulse washing, the distributed fault self-diagnosis module monitors and early warns faults in real time, and flexible expansion and
system compatibility are achieved through a
modular architecture. According to the system, accurate deslagging, anti-blocking, energy-saving and stable operation under the high-concentration
slag-containing working condition are achieved, and the operation adaptability and the operation and maintenance convenience are improved.
