  • Effects of Double Stage Venturi Scrubber Nozzle on the Liquid Injected Flow

抄録

<p>The Venturi Scrubber is one of the most effective nozzles for the wet-scrubber type Filtered Containment Venting System. The advantage of a Venturi Scrubber nozzle is that it is capable to remove dust particles and radioactive gas materials due to contact with the liquid droplets which are atomized into the throat of the nozzle. Therefore, the efficiency of the venturi scrubber also depends on the atomized water flow rate. In this study, the effects of the double-stage venturi on the on the atomized water flow rate was investigated at several conditions of the air injected flow rate. Two configurations of the venturi scrubber nozzle were used. The velocity of water at the gaps of the nozzle was measured using Ultrasonic Velocity Profiler method. The results showed that the water velocity was decreased as increase of the air injection flow rate.</p>
