Deep-sea mining tail water discharge plume restraining device
The invention relates to a deep-sea mining tail water discharge plume restraining device. The device comprises a mineral tail water discharge pipe, a plume restraining pipeline cover and damping fins, wherein a tail water inlet of the plume restraining pipeline cover is fixedly connected with the mineral tail water discharge pipe, the multiple damping fins are fixedly connected in the plume restraining pipeline cover, and in the direction from a tail water inlet to a tail water outlet, the sizes of the damping fins are gradually increased. According to the deep-sea mining tail water discharge plume restraining device, the flowing speed of discharged tail water is effectively reduced through a unique damping structure (the effective discharge sectional area of the restraining device exceeds the sectional area of the tail water discharge pipeline by at least 30%, such that the tail water discharge efficiency is not affected), the diffusion speed of plume sediment is remarkably reduced, and therefore, the influence of tail water discharge particulate matter on benthic organisms and the marine environment is controlled within the minimum degree.
本发明涉及一种深海采矿尾水排放羽流抑制装置，包含矿物尾水排水管、羽流抑制管路罩、阻尼片，所述羽流抑制管路罩的尾水入口固定连接矿物尾水排水管，所述羽流抑制管路罩内固定连接多个所述阻尼片，且从尾水的入口到出口方向，阻尼片尺寸逐渐增大。本发明的深海采矿尾水排放羽流抑制装置通过其独特的阻尼结构来有效的降低排放尾水的流动速度(因抑制装置的有效排放截面积超尾水排水管路截面积至少30％，尾水排放的效率不会受影响)，显著降低羽状流沉积物扩散的速度，从而将尾水排放颗粒物对海底生物及海洋环境的影响控制在最小程度内。
