摘要
A seawater deaerator has a large reservoir through which seawater slowly flows. Gas is injected into the bottom of the reservoir through porous aeration stones forming bubble nuclei. The seed bubbles move upward through the seawater in the reservoir expanding but not coalescing, and withdrawing dissolved gas from the seawater. The deaerated seawater flows out of the reservoir and subsequently flows through spouts into a flash evaporator. Gas is withdrawn from a low pressure gas chamber at the top of the reservoir by a vacuum pump. The exhaust of the vacuum pump supplies gas to the air injectors.
