工业水力旋流器预处理疏浚含泥海水模拟试验研究

Simulation Experiment of Industrial Hydrocyclone Pretreatment for Dredging Muddy Seawater

采用水力旋流器开展疏浚含泥海水处理模拟试验研究,结果表明其对粒径约30μm的颗粒去除率可达76%以上,对粒径约40μm的颗粒去除率可达83%以上,混合粒径更有利于小粒径颗粒去除率的提高。研究结果为海上疏浚船舶海水淡化预处理系统运行存在的问题提出了新的解决思路,但如何达到更高的去除率需要进一步深入研究。

The hydrocyclone was proposed for the simulation test of ocean dredged sediment treatment.The results showed that the removal rate of particles about 30μm can reach more than 76%,the removal rate of particles about 40μm can reach more than 83%.Mixing particles of different sizes together is more beneficial to improving the removal rate of small particles.The research results provided a new solution to the problems existing in the operation of seawater desalination pretreatment system for dredged ships.However,how to achieve higher removal rate need further study.
