UPPER FLOW DRAINAGE APPARATUS FOR SUSPENDED SEDIMENT FLOATATION REMOVAL TYPE APPROACHING CHANNEL OF THERMAL POWER PLANT

摘要

The present invention relates to an upstream selective discharge device for removing floating sand floating by a bubble in a floating sand floating type access channel of a thermal power plant such as a nuclear power plant or a thermal power plant. It consists of a traversing upper barrier plate and an overflow channel provided on the side wall of the access channel.;Through the present invention, it is possible to effectively discharge the upper layer flow while maintaining the tranquility of the access water to the maximum, thereby minimizing the destruction of bubbles and foam formed in the upper layer flow to obtain the effect of improving the removal performance of the floating sand.
