FIELD: machine building.SUBSTANCE: desalination multistage adiabatic plant additionally comprises a thermosoftener (52) which serves for the generation of sludge particles in the feed water heated in a steam heater (26) and taken from a pipeline to supply the feed water to the inlet of a multi-stage adiabatic evaporator (4), as well as a two-section feed water receiver (76) to reduce supersaturation in the sea water being evaporated due to the usage of sludge particles as "seed crystals" in the supersaturated solution volume. The thermosoftener (52) comprises a perforated membrane (56) built-in in the casing (53) under the cover, a dome-shaped horizontal partition (61) installed with a gap in respect to the inner casing wall, vertical cylindrical shells, a manifold to withdraw the vapour (62) under the dome-shaped partition, a branch pipe for water withdrawal is united with the sludge particle removal and is mounted in the casing bottom, and the branch pipe for steam supply is built-in in the casing cover.EFFECT: lower rate of scale formation on working surfaces of the plant elements.2 cl, 9 dwg |
