深海多金属硫化物集矿罩的流场分析和参数优化
Flow field analysis and parameter optimization of deep-sea collector of SMS
摘要
Abstract
On the basis of a new deep-sea polymetallic sulfide mining device, the fluid under the double spiral drum collecting hood was used to study the complex multiphase flow which may be formed during the sulfide collection process and the possible impact on the surrounding marine environment pollution and other issues, coupled SIMPLE algorithm and RNGk?ε turbulence model of the CFD software Fluent were used to simulate and analyze, a number of physical parameters were chosen for optimization, such as the center distance between two spiral drums, drum speed, rotation direction, mineral accumulation height, the ore diameter, pumping velocity and so on. The results show that the distance of two drums has the optimum value to reach the optimal pumping effect. Seawater at the entrance of the speed is not the faster the better, when the speed reaches 2 m/s, shortening the pumping time effect is not obvious. The opposite direction of drums can reduce the time of pumping. Mineral particle size also has slight impact on pumping time.关键词
