The reverse osmosis device 2 comprises a permeation tube 21 and an RO membrane 22 arranged in the permeation tube 21; the osmosis pipe 21 is divided into a seawater end 23 and a fresh water end 24 by an RO membrane 22, the seawater end 23 is connected with a osmosis water inlet pipe 25, and the fresh water end 24 is connected with a osmosis water outlet pipe 26; the seawater end 23 is provided with a high-pressure cavity 27 above the liquid level, and the fresh water end 24 is provided with a low-pressure cavity 28 above the liquid level; by increasing the air pressure in the high pressure chamber 27, water molecules in the sea water side 23 are increased to pass through the RO membrane 22 to the fresh water side 24.
The flash evaporation device 3 includes a flash evaporation tank 31, a flash evaporation water inlet pipe 32 connected to the flash evaporation tank 31, a water collecting tank 33 for collecting condensed fresh water, a flash evaporation water outlet pipe 34 for discharging fresh water, and a water outlet pipe 35 for discharging seawater; the flash evaporation water inlet pipe 32 is sequentially connected with a heating pipe 36, a preheating pipe 37 and a pretreatment pipe 38 which are positioned in the flash evaporation box 31, and the flash evaporation water inlet pipe 32 is provided with a pressure relief valve; the water vapor is heated to a specified temperature by a heating pipe 36, the air pressure in the flash tank 31 is regulated to a specified saturated vapor pressure, the seawater at one end of the heating pipe 36 is led into the flash tank by a pressure relief valve, the seawater in the flash tank 31 is rapidly evaporated, and the evaporated water vapor is condensed to form fresh water and enters the water collecting tank 33.
The evaporation water inlet pipe 12, the permeation water inlet pipe 25 and the pretreatment pipe 38 are all filled with pretreated seawater; the pretreatment tube 38 is located at or near the optical focal point of the condenser lens 14 in the evaporation tank 11; the straight line formed by the focal point of the condensing lens 14 coincides with the length direction of the pretreatment tube 38; so that the seawater in the pretreatment pipe 38 can be preheated by the condensing lens, and the seawater temperature is increased; the condensation water outlet pipe 13 is communicated with the low-pressure cavity 28; the water vapor in the condensation water outlet pipe 13 enters the low-pressure cavity 28 and is condensed into water to enter the fresh water end 24; the flash evaporation device also comprises an air pump 4, wherein the air inlet end of the air pump 4 is communicated with the flash evaporation box 31, and the air outlet end of the air pump is communicated with the high-pressure cavity 27; the air pump 4 makes the air pressure in the flash evaporation tank 31 reach the saturated vapor pressure of water, the specific pressure value of the air pump corresponds to the water temperature at the flash evaporation water inlet pipe 32, namely, when the water temperature in the flash evaporation water inlet pipe 32 is 95 ℃, the saturated vapor pressure in the flash evaporation tank 31 is not more than 84.56KPa, so that the heated seawater can be vaporized in the flash evaporation tank 31 to generate steam after the flash evaporation water inlet pipe 32 is opened through the pressure relief valve, and the steam is collected through the water collecting tank 33 after condensation and then is discharged through the flash evaporation water pipe 34.

The pressure in the flash tank 31 is maintained at a value of saturated vapor pressure by providing the intake pressure stabilizing valve 41 to avoid the pressure in the flash tank 31 from being too low; by setting the air outlet pressure stabilizing valve 42, the pressure in the high pressure cavity 27 is at a stable value, so that the influence of the excessive high pressure or the excessive low pressure on the reverse osmosis or the reduction of the service life of the RO membrane is avoided.

The working pressure in the high pressure chamber 27 is 1.5-2MPa. When the air pressure in the low-pressure cavity 28 is too high, the piston rod 53 is pushed to shrink, the whole cavity space is increased, so that the air pressure is reduced, and when the air pressure is further increased, the air pressure in the low-pressure cavity 28 is ensured by exhausting through the pressure limiting valve 55; when the water vapor entering the low-pressure cavity 28 is reduced or the air pressure value in the low-pressure cavity 28 is lower due to the temperature reduction, the air is introduced through the one-way air inlet valve 56 to stabilize the air pressure value in the low-pressure cavity 28, so that the air pressure value in the low-pressure cavity 28 is kept relatively consistent with the atmospheric pressure; by arranging the pressure stabilizing component 5, the water vapor entering the low-pressure cavity 28 from the evaporation tank 11 can be fully condensed and enter the fresh water end 24, and the influence of the excessive air pressure increase caused by the excessive temperature on the reverse osmosis of the reverse osmosis device 2 can be avoided, so that the fresh water is collected to the greatest extent.
The flash tank 31 is communicated with the low-pressure cavity 28, and a condensing cavity 43 is arranged on a pipeline between the flash tank 31 and the low-pressure cavity 28. The water vapor which is not condensed in the flash tank 31 enters the condensation cavity 43 through a pipeline for further condensation and then is gathered into fresh water in the fresh water end 24.
Further, the evaporated seawater in the evaporation tank 11 can be further connected to a specific flash tank 31 via a pipeline.
Further, in order to pre-heat the pretreated seawater, the seawater passing through the drain pipe 35 of the flash tank 31 of the last stage may be heat-conducted to heat the pretreated seawater pipeline, thereby reducing heat loss and improving heat energy utilization rate.
The pretreatment pipe 38 is arranged in the evaporation tank 11, so that the seawater in the evaporation tank 11 is preheated while the seawater in the pretreatment pipe 38 is evaporated, and the heating time of the heating pipe 36 in the subsequent process is saved; the air pressure in the flash tank 31 is reduced and the pressure in the high-pressure cavity 27 is increased by arranging the air pump 4, and the water vapor remained in the flash tank 31 is further transmitted to the seawater end 23 in the reverse osmosis device 2 for supplementing the fresh water after the single flash evaporation process is finished, so that the speed of crystallization accumulation at the RO membrane caused by the increase of the seawater concentration is slowed down; by arranging the combined seawater desalination systems in various forms, all the devices are mutually cooperated and promoted, so that the consumption of energy sources is saved, and the persistence of the seawater desalination process is ensured.
