海底多金属结核的管道水力输送

Hydraulic Pipeline Conveyance of Seabed Multi-Metallic Nodules

从海洋底部采集多金属结核是人类利用自然资源的可持续发展目标。目前,可行的采矿运输系统乃是将结核与海水混合的浆体通过管道输送到海上的集矿船。本文综述了这一浆体管道输送应用的现况和若干国内外试验研究和技术发展,并重点介绍结核输送系统的主要部分,即硬管装置及其试验研究成果。

Collection of seafloor multimetallic nodules is a target for sustainable development in the field of the utilization of natural resources. The general system in current use is to convey the nodule and seawater mixture onto the ship via pipeline in slurry form. A general survey is made in the paper of the state—of—the—art of the system and the experimental study and technical development made in this respect, with the emphasis placed on the key part, i.e. the hard—pipe unit and its study result.
