MOISTURE SEPARATION DEVICE

摘要

It is intended to provide a moisture separator that is capable of suppressing the performance drop of the moisture separation even with an increased height of a corrugated plate by suppressing increase in thickness of the liquid film formed by the moisture collected by the corrugated plate and by suppressing the re-entrainment of the moisture collected by the corrugated plate. The corrugated plate 43 is provided with a collecting plate 49 formed such as to cover a flat portion 74 and an upstream end of a slope portion 72 disposed on a downstream side of the flat portion 74. The collecting plate 49 has an opening which opens to moist steam flow S1. The collecting plate 49 is fixed to the slope portion 72 at a base end thereof. Between the collecting plate 49 and a body portion of the corrugated plate 43, a pocket section 47 and a drain duct section 48 are formed. The moisture contained in the moist steam S1 turns into droplets and enters the pocket section 47 and the drain duct section 48 from the inlet opening of the collecting plate 49 and flows down inside the pocket section 47 and the drain duct section 48 respectively by gravity.
