Description

Technical field [0001] The invention relates to an iron concentrate slurry pipeline accelerated flow energy dissipation and energy feedback device and a control method thereof, and belongs to the technical field of fluid acceleration flow energy dissipation energy feedback equipment. Background technique [0002] Long-distance slurry pipeline transportation systems are often laid in mountainous areas with rugged terrain. Due to the difference in elevation between the starting point and the end point or the difference in the proportion of slurry and water during batch transportation, a common problem in slurry hydraulic analysis will be caused, that is, slurry pipeline acceleration flow. The generation of this accelerated flow is actually caused most by the excess energy, which usually forms a dissatisfaction flow similar to an open channel when the pipe is full and is automatically consumed. The speed of this accelerated flow may exceed the flow rate of the normal full pipe flow...

Problems solved by technology

This method is an ideal method for energy dissipation, but this method wastes most of the energy, and the energy of energy dissipation is not recovered well, which is an uneconomical way

[0006] In the long-distance pipeline slurry transportation project, the pipeline works 24 hours under normal working conditions, and the accelerated flow energy dissipation of the pipeline is carried out 24 hours without interruption. The energy dissipation of the traditional method for many years wastes a lot of energy.
