摘要

摘要: 水域漂浮垃圾污染治理,是水域生态建设的重要方面。水上漂浮垃圾收集器可通过负压产生吸力自主收集水面漂浮垃圾。目前漂浮垃圾收集器的负压产生方式由水泵排水产生,介绍了一种自主研发的基于漩涡吸力与螺旋桨排水现象,以及伯努利定常流定理的涡吸式收集器,利用CFD仿真对收集器处于不同水流状态下的排水能力进行模拟分析,并通过室内水池漂浮物收集实验进行了补充验证。结果表明:涡吸式收集器在0~2.5 m/s的流速以及在-10°~10°的水流入射夹角范围内,其排水效率均高于泵压式收集器,但在水流入射角度在-15°和15°情况下,涡吸式收集器受模型规格限制,无法正常工作。进一步通过室内水池漂浮物收集实验,验证了涡吸式收集器可快速完成收集,适用性良好。

Abstract: Pollution control of floating garbage is an important part of water area ecological construction. The floating garbage collector on the water can collect floating garbage on water surface by generating suction through negative pressure. At present, the negative pressure of the floating garbage collector is generated by water pump drainage. This paper introduced a vortex suction collector based on the vortex suction and propeller drainage phenomenon, and Bernoulli’s steady flow theorem. The drainage capacity of the collector under different flow conditions was simulated and analyzed by CFD simulation, and verified by the indoor pool floating object collection experiment. The experimental results showed that the drainage efficiency of the vortex suction collector was higher than that of the pump pressure collector under the flow velocity of 0 m/s to 2.5 m/s, and the incidence angle of -10° to 10°. However, the vortex suction collector was limited by the model specification and couldn’t work normally under the incidence angle of -15° and 15°. Furthermore, in the indoor pool floating object collection experiment, the vortex suction collector quickly completed the collection, which proves its good applicability.
