Vertical evaporator

Abstract

Abstract A vertical evaporator has an inner tube containing a heat exchanger for heating water and an outer tube which is coaxial with and surrounds the inner tube, forming a sealed system and defining a peripheral space between the two tubes. The inner tube has bottom outlets through which steam and water droplets generated by heating water by the heat exchanger are ejected. A helical fin is attached to the outer surface of the inner tube for centrifugally separating steam and water droplets moving upward inside the peripheral space in a helical manner. The outer tube has a steam outlet at an elevated position for discharging pure steam separated from water droplets, as well as a channel above the helical fin for collecting water droplets which are centrifugally separated from steam. A discharge pipe is also provided, leading to the channel for discharging water collected therein.
