2. Description of the Related Art Conventionally, by heating water containing salt such as seawater to evaporate water and condense the water vapor,
A salt water desalination apparatus for obtaining fresh water which is water free of salt is a well-known apparatus. The apparatus usually employs the generated steam to heat and evaporate the salt water in the low-pressure section, which is often a so-called multiple effect. At this time, by degassing the salt water to be introduced, corrosion of the salt water desalination apparatus can be suppressed, and deterioration of heat transfer in the steam condensing section can be prevented. That is,
Since the non-condensable gas collects in the condensed portion, when the steam reaches the heat transfer surface, it must pass through the non-condensable gas layer by diffusion, and the heat transfer is significantly deteriorated. In the deaeration of salt water, the use of an oil vacuum pump sucks water vapor, so that maintenance of oil is frequently required, which is not preferable. In addition, since the dry rotary vacuum pump sucks water vapor, there is a problem of corrosion, and a simple structure has a difficulty in reaching a degree of vacuum.
