Dynamic blender, it is effective to be placed in right position for two-position three-way hand change valve 14 at this time, and open common valve 4, then starting pump 11,
After seawater is via pump 11 at this time, flow into containing in the extremely supersaturated closed container 36 of NaOH.In the initial stage, closed container is utilized
The air of 36 tops transmits the pressure from seawater, by bottom it is hydraulic enter 19 body absorption carbon dioxide of vaporization chamber, when vacuum degree is suitable
It after formation, pumps 11 continuous extracting seawaters of need and is supplemented, until being closed in time after the reading of pressure gauge meets vacuum level requirements
Close common valve 4.Finally close common valve 4 and pump 11.
4. opening pump 12 at this time, and common valve 5 and 7 is opened, under the action of pumping 12, absorbs the vaporization chamber of high-purity
Seawater comes concentration of seawater detection device 29, at this time due to seawater intermediate ion concentration pole via common valve 5,7 and pump 12 in 19
Height can trigger concentration of seawater detection device 29 and issue signal, so that the right position of two-position three way magnetic valve 15 effectively (notes: low concentration
Kingston valve 15 be that left position is effective always), concentrated seawater just smoothly flow into concentrated seawater holding vessel 28 in.In 19 bottom seawater of vaporization chamber
After extraction, common valve 5 and 7 is closed in time, and stop pump 12.
In this way, just foring vacuum environment after above-mentioned steps.
Two, sea water desalination workflow
It is effective that two-position three-way hand change valve 14 is placed in left position, opens pump 11 at this time, and open common valve 3, seawater
Just check valve 8 (another branch is in and blocks state, and compared in the tank of vacuum environment, seawater be may not flow into) is flowed through, and via general
Port valve door 3 enters the spray equipment in tank, and is 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
It crosses electric heating ancillary 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 hot steam of sea water desalination.
When initial hot steam rises to 19 top of vaporization chamber, with the liquid and/or fresh water collecting dress inside loop circuit heat pipe 21
20 carry out heat exchanges are set, are collected after liquefaction as fresh water.
Gasification is gas after liquid absorption inside loop circuit heat pipe 21 latent heat of liquefaction of the outer steam of pipe, in power device 35
Adsorption force under, be transported in the pipeline below solar energy heating tube wall and solar energy heating tube wall be together under spray
The moisture film come is evaporated, and the gas in pipe, which just liquefies, becomes liquid, is transmitted by power device 35 or another power device
It is recycled to top.
Preferably, power device 35 is power-equipment or capillary pump.
When there is enough liquid in 19 bottom set portion of vaporization chamber, stop pump 11, open pump 12, and open common valve 5 and 7,
Concentration of seawater is lower at this time, 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, solenoid valve 15, common valve 3 are recycled into spray equipment.When concentration of seawater is excessively high, seawater passes through Concentration Testing
Information is issued after device, obtains two-position three way magnetic valve 15 electric, is in right position effective status, and such seawater just flows into concentrated seawater storage
Deposit tank.
Preferably, can return to when seawater is approached and drained close to step 4 state for vacuumizing link；In order to facilitate behaviour
Make, 11 work of pump can also be made again, new seawater is added while extracting seawater, when concentration reduces, two-position three way
Solenoid valve 15 can power loss to come back to left position effective, continue cycling through and utilize bottom seawater.
In this way, just can work the repetition period, accent starts when tank interior vacuum degree is undesirable.
