Abstract

The invention relates to an integrated solar seawater self-circulation desalting device which is used for obtaining fresh water from seawater by utilizing solar thermal energy. A glass through tube solar heater, a flash chamber, a fixed tube plate condenser, a water pump, a water ring vacuum pump and a water reservoir are integrated on a substrate; the upper part of the glass through tube solar heater is communicated with the upper part of the flash chamber; the lower part of the glass through tube solar heater is communicated with the lower part of the flash chamber through a connecting tube; the top part of the flash chamber is communicated with the top part of the fixed tube plate condenser; the bottom part of the fixed tube plate condenser is communicated with an air sucking port of the water ring vacuum pump; an air discharge port of the water ring vacuum pump is communicated with the water reservoir; the upper part of a shell pass of the fixed tube plate condenser is communicated with the bottom part of the glass through tube solar heater through a seawater intake valve; the lower part of the flash chamber and the upper part of the shell pass of the fixed tube plate condenser are gathered together through a thick seawater discharge valve and a seawater discharge valve and are subsequently communicated with the water pump; an anodic sacrifice protection block is installed below the water level inside the flash chamber.

Description

technical field [0001] The invention relates to an integrated solar seawater self-circulation desalination device for obtaining fresh water from seawater by utilizing solar thermal energy, and belongs to the field of seawater desalination equipment manufacturing. Background technique [0002] CN1049643A, titled "Method and device for seawater desalination using natural energy", absorbs natural heat energy from sea surface water and then evaporates, steam drives steam turbine generator to generate electricity, and exhaust steam from turbine is condensed into fresh water. Its characteristics are: a natural energy heater is connected with the inlet of a steam flash evaporator, a recirculation heat recovery device is respectively connected with the inlet of the natural energy heater and the discharge port of the flash evaporator; the outlet of the flash evaporator is connected with the inlet of the steam turbine , the exhaust hole of the steam turbine is closely connected with t...
