At 99.9999% carbon dioxide storage tank access valve 2, and common valve 6 and 5 is opened successively, while carbon dioxide is stored up
The valve for depositing tank is opened, and so, under carbon dioxide gas pressure effect, seawater is just flow back into seawater holding vessel from bottom.
When being full of high-pureness carbon dioxide in vaporization chamber 19, pay attention to closing common valve 2,5 and 6 in time.
3. by enough alkaline matters, such as container 36 of the NaOH inputs containing appropriate bottom liquid, then by container closure and open
Dynamic agitator, it is effective that two-position three-way hand change valve 14 is now placed in right position, and opens common valve 4, then start pump 11,
After now seawater is via pump 11, flow into containing in the extremely supersaturated closed vessels 36 of NaOH.In the starting stage, closed container is utilized
Pressure of the air transmission from seawater of 36 tops, enters the body absorption carbon dioxide of vaporization chamber 19, when vacuum is fitted by bottom hydraulic pressure
After formation, 11 continuous extracting seawaters of need of pump are supplemented, until after the reading of pressure gauge meets vacuum level requirements, are closed in time
Close common valve 4.Finally close common valve 4 and pump 11.
4. now opening pump 12, and common valve 5 and 7 is opened, in the presence of pump 12, absorb the vaporization chamber of high-purity
19 maritime interior waters come concentration of seawater detection means 29, now due to seawater intermediate ion concentration pole via common valve 5,7 and pump 12
Height, concentration of seawater detection means 29 can be triggered and send signal so that 15 right position of two-position three way magnetic valve effectively (pays attention to：Low concentration
Kingston valve 15 be that left position is effective all the time), concentrated seawater is just smoothly flowed into concentrated seawater holding vessel 28.In the bottom seawater of vaporization chamber 19
After extraction terminates, common valve 5 and 7 is closed in time, and stop pump 12.
So, after above-mentioned steps terminate, vacuum environment is just formd.
2nd, desalinization workflow
It is effective that two-position three-way hand change valve 14 is placed in left position, now opens pump 11, and open common valve 3, seawater
Just check valve 8 (another branch road is in and blocks state, and compared in the tank of vacuum environment, seawater may not flow into) is flowed through, and via general
The spray equipment that port valve door 3 enters in tank, and be atomized seawater by spray equipment.
After working medium in pipeline is heated to 80 degrees centigrades by the absorption solar energy of solar thermal collector 30, high temperature refrigerant stream
Cross electrical heating auxiliary equipment 31 and heat exchanger 32 enters inside vaporization chamber 19.In vaporization chamber 19, spray in solar energy heating pipe
The heat of high temperature refrigerant in the moisture film absorption tube of wall and gasify, form the initial vapours of desalinization.
When initial vapours rises to 19 top of vaporization chamber, filled with the liquid inside loop circuit heat pipe 21 and/or fresh water collecting
20 carry out heat exchanges are put, it is collected after liquefying as fresh water.
It is gas to gasify after liquid absorption inside loop circuit heat pipe 21 latent heat of liquefaction of the outer steam of pipe, in power set 35
Absorption affinity effect under, be transported in the pipeline below solar energy heating tube wall, and solar energy heating tube wall is together under spray
The moisture film come is evaporated, and the gas in its pipe just liquefies as liquid, is transmitted by power set 35 or another power set
Recycled to top.
Preferably, power set 35 are power-equipment or capillary pump.
When there is enough liquid in the bottom set portion of vaporization chamber 19, stop pump 11, open pump 12, and open common valve 5 and 7,
Now concentration of seawater is relatively low, and two-position three way magnetic valve 15 is in left position effective status, the seawater of tank bottom by common valve 5 and 7,
Pump 12, magnetic valve 15, common valve 3 are recycled into spray equipment.When concentration of seawater is too high, seawater passes through Concentration Testing
Information is sent after device, obtains two-position three way magnetic valve 15 electric, in right position effective status, such seawater just flows into concentrated seawater storage
Deposit tank.
Preferably, when seawater is approached and drained, can return to close to step 4 state for vacuumizing link；In order to facilitate behaviour
Make, also pump 11 can be made to work again, new seawater is added while extracting seawater, when concentration reduces, two-position three way
Magnetic valve 15 can dead electricity to come back to left position effective, continue cycling through and utilize bottom seawater.
So, just can work the repetition period, when tank interior vacuum is undesirable accent start.

Described intercommunicating pore 41 is circular configuration, along thermal-collecting tube 38 in fluid flow direction, the circular configuration
Radius constantly increases.
Because the flow direction of fluid in along thermal-collecting tube 38, the fluid in thermal-collecting tube 38 constantly even evaporate by heat absorption,
Hence in so that the pressure of thermal-collecting tube constantly increases, and because the presence of intercommunicating pore 41 so that the pressure inside thermal-collecting tube 38
Distribution is more and more uniform, therefore the area needs of intercommunicating pore are very big, constantly becomes big by setting, so that in guarantee heat pipe
In the case of the uniform pressure of internal pressure, increase heat exchange area by connecting the change of hole area, so as to improve heat exchange effect
Rate.
