摘要

摘要: 為解決小倍線充填管道局部壓力過大、管路磨損嚴重等問題,本文提出用螺旋管增阻調壓的結構與實施方案.結合計算流體力學（computational fluid dynamics,CFD）對增阻調壓結構與實施方案進行模擬分析,基于模擬計算的結果提出增加螺旋管道增阻調壓結構后計算充填倍線的修正公式.研究結果表明,在2 m·s^-1的模擬流速下,螺旋管增阻調壓結構所產生的阻力可達同等高度直管的10.1~16.8倍,在保證料漿連續輸送的前提下可以有效的起到增阻降壓的作用.結合數值模擬的充填倍線修正公式能夠較為完善地計算增阻降壓后的有效充填倍線.

Abstract: In order to solve the high pressure and serious worn problems at some sections in a low stowing gradient backfilling pipeline, this article introduces a new solution of spiral pipes to regulate the resistance and pressure. The regulator of increasing resistance and its implementation plan are analyzed by using the CFD technique. An amended formula for calculating the stowing gradient is presented by adding spiral increasing resistance based on the simulation. It is shown that, when the transportation speed is 2 m·s^-1, the unit-height resistance of the spiral pipe can be 10.1 to 16.8 times that of the straight pipeline. This apparatus can fully guarantee the continuous conveying of slurries, and it can also increase the resistance and reduce the pressure effectively. The amended formula can figure out the effective stowing gradient of the backfilling pipeline with spiral apparatus more accurately.
