Abstract

The invention belongs to the technical field of pipeline slurry conveying, and relates to a pipeline gas adding resistance reduction slurry conveying device. The pipeline gas adding resistance reduction slurry conveying device achieves the technical aims that flowing resistance of slurry in the pipeline is reduced, and hydraulic losses of the slurry along the way are reduced; in order to achieve the aims, the pipeline gas adding resistance reduction slurry conveying device comprises an outer pipe wall, an inner pipe wall, a high-pressure gas way, a high-frequency vibrator, a gas film generation way and a high-pressure air inlet; the high-pressure gas way is arranged between the outer pipe wall and the inner pipe wall, the high-frequency vibrator is arranged in the high-pressure gas way, the gas film generation way is arranged on the inner pipe wall, and the high-pressure air inlet is connected with the high-pressure gas way; the defects that the flowing resistance of the slurry in the pipeline is large, and hydraulic lowering along the way is rapid are overcome, and the effects that the flowing resistance of the slurry in the pipeline is reduced, and the hydraulic losses of the slurry along the way are reduced are achieved.

Description

technical field [0001] The invention belongs to the technical field of pipeline mud transportation, and relates to a pipeline gas-filling and drag-reducing mud transportation device. Background technique [0002] On the dredger for channel dredging, the dredging pump sucks up the cut mud, and transports the mud from the dredging point to the far-distance sludge storage and processing point through the large-diameter and long-distance mud pipeline. Due to the characteristics of the dredged mud, which has many components, high concentration, and large flow rate, the mud is in a multiphase flow state when it is transported in the pipeline, and its flow velocity is greatly disturbed and the flow field is complex. As a result, the flow resistance of mud in the pipeline is large, and the hydraulic pressure drop along the way is fast, which often leads to pipeline wear, blockage, short transportation distance and high energy consumption of the dredger's mud transportation system, w...
