Noise controller for falling water - has overflow weir close to side wall of drain trench to raise pool level and has cover over trench

摘要

The noise controller is for a vaporising device of the open frame type with a water spray unit to spray sea water from a water spray pipe on the tip of the heat exchanger onto the surface of the heat exchanger in film form. There is a pool to accept the sea water from the surface of the heat exchanger and for draining the sea water into a drain trench. Specifically, there is an overflow weir (9) close to the side wall of the drain trench (8) to raise the water level of the pool (7). Further, the distance from the bottom of the bottom collection - or distributor tank (2) of the heat exchanger up to the water surface of the pool (7) is less than 500 mm.
