The concentration of plume caused by hydraulic collecting system during deep-sea polymetallic nodules mining under different working conditions were analyzed. Test results show that the concentration of discharged plume from conveying system is much higher than that of sediment plume caused by the disturbance of capture system, which is one of the main causes of turbidity current in the sea. In the test, the curve of slurry concentration presented a steep upward trend line followed by a steep downward line. Increasing oil pressure of the pump of capture system will lead to higher concentration of slurry. However, the oil pressure of the pump of conveying system won't result in obvious variation in slurry concentration.

研究了海底多金属结核水力式集矿系统在不同工况条件下产生的污泥浓度。结果表明,海底多金属结核水力式集矿系统中输送系统脱泥排放产生的污泥浓度远高于捕捉系统扰动底质淤泥产生的污泥浓度,是产生水体浑浊的主要原因之一。试验过程中污泥浓度变化曲线呈现先迅速上升后快速下降的变化趋势,随着捕捉系统水泵油压增大,污泥浓度增大;输送系统水泵油压对污泥浓度影响不明显。

研究了海底多金属结核水力式集矿系统在不同工况条件下产生的污泥浓度。结果表明,海底多金属结核水力式集矿系统中输送系统脱泥排放产生的污泥浓度远高于捕捉系统扰动底质淤泥产生的污泥浓度,是产生水体浑浊的主要原因之一。试验过程中污泥浓度变化曲线呈现先迅速上升后快速下降的变化趋势,随着捕捉系统水泵油压增大,污泥浓度增大;输送系统水泵油压对污泥浓度影响不明显。

The concentration of plume caused by hydraulic collecting system during deep-sea polymetallic nodules mining under different working conditions were analyzed. Test results show that the concentration of discharged plume from conveying system is much higher than that of sediment plume caused by the disturbance of capture system, which is one of the main causes of turbidity current in the sea. In the test, the curve of slurry concentration presented a steep upward trend line followed by a steep downward line. Increasing oil pressure of the pump of capture system will lead to higher concentration of slurry. However, the oil pressure of the pump of conveying system won't result in obvious variation in slurry concentration.
