Abstract

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.
