MSF desalination apparatus with heat-pipe heat dissipater

摘要

Disclosed is a MSF seawater desalination apparatus with a pipe-type heat dissipater (50), which allows fresh water, extracted by a heat recovery unit, to be cooled by the pipe-type heat dissipater and be discharged to the outside without passing through a heat dissipation unit. The MSF seawater desalination apparatus, which heats seawater by heat exchange with steam of a high temperature, allows the heated seawater to sequentially pass through a heat recovery unit (20) and a heat dissipation unit (30) so as to produce fresh water through evaporation and condensation, and has a vacuum system provided with a plurality of condensers (41) achieving heat exchange between the seawater and the high-temperature and high-pressure steam so as to maintain a vacuum state in the heat recovery unit. The MSF seawater desalination apparatus significantly reduces the amount of cooling seawater supplied to the heat dissipation unit so as to decrease ecosystem destruction in the coast due to heated seawater.
