Problems solved by technology

[0003] Moreover, when the slurry flow rate is too low, the solid coarse particles in the slurry will stay in the pipeline. If it is not treated for a long time, the pipeline will be blocked, which will seriously affect the safe and stable operation of the pipeline.

Abstract

The invention relates to a method for monitoring the grain diameter of ore pulp transported by a long-distance pipeline in a complex terrain, which is characterized by comprising the following steps of dynamically monitoring whether the coarse grain ore pulp retains in the pipeline or not by detecting and analyzing the change of the grain diameter in the positions of a starting point and a finishing point in the running course of the long-distance pipeline; and monitoring whether the ore pulp is completely transported in the transportation course of the pipeline and whether the overstocking phenomenon of coarse grains in the pipeline appears so as to timely avoid the loss because the ore pulp with coarse grain diameter is overstocked in the pipeline.

Description

technical field [0001] The invention relates to a method for monitoring the safe operation of a transportation pipeline, in particular to a method for monitoring the particle size of ore slurry transported by a long-distance pipeline with complex terrain. Background technique [0002] During the long-distance slurry pipeline transportation of solid materials, the particle size of the solid slurry changes under the action of hydraulic force, pressure and mutual friction, which directly affects the wear and corrosion of the pipeline. [0003] Moreover, when the flow rate of the slurry is too low, the coarse solid particles in the slurry will remain in the pipeline. If left untreated for a long time, the pipeline will be blocked, which will seriously affect the safe and stable operation of the pipeline. Contents of the invention [0004] The present invention designs a method for monitoring the particle size of ore slurry transported by long-distance pipelines with complex te...
