Abstract

An energy-saving seawater distilling method and a device thereof utilize solar energy and vacuum generated by the device in itself to boil seawater, generated steam is subjected to condensation to generate needed distilled water. The device comprises a seawater overflow pool and an evaporator, wherein a seawater inflow pipe, a seawater outflow pipe are arranged between the seawater overflow pool and the pipe ends are provided with valves, the seawater overflow pool is thereon provided with an overflow port; the device further comprises a fresh water overflow pool and a condenser, wherein the fresh water overflow pool is thereon provided with an overflow port communicated with fresh water pool, and the condenser comprises a shell and a condensing coil, the shell is thereon connected with aseawater inlet pipe, a seawater outlet pipe; two ends of the condenser is connected with the evaporator and the fresh water overflow pool; the space of the upper half part of the inner chamber of theevaporator is a first vacuum chamber, the space between an inner chamber of the upper end of a fresh water pipe and an inner chamber of an external pipeline of the upper end of a condensation pipe isa second vacuum chamber; the two vacuum chambers are communicated with each other by a pipeline; the seawater inlet pipe is thereon connected with an initial seawater inlet branch pipe and an inlet valve thereof, and is communicated with seawater pumps; fresh water pumps are arranged above the fresh water pool, an inlet end and an outlet end thereof are communicated with each other by a fresh water outlet pipe, and the fresh water outlet pipe is thereon provided with a fresh water supply port.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and relates to a seawater desalination device, in particular to an energy-saving seawater desalination device. Background technique [0002] In the prior art, there are various methods for desalination of seawater, such as boiling method, flash evaporation method and reverse osmosis method. [0003] The boiling method mainly uses the principle of boiling distillation to produce fresh water from seawater, and the seawater is converted into fresh water through boiling, evaporation, separation and condensation in the device. [0004] The flash evaporation method is usually multi-stage, and its main principle is: under a certain pressure, the preheated seawater is heated to a certain temperature, introduced into the first flash chamber, and the pressure is reduced to make the seawater flash evaporate, resulting in The steam condenses outside the heat exchange tube to form fresh water, ...
