Then water supply loop is started to work, i.e. solenoid valve a2 is opened, and fluid level controller 5 is according to raw water in sealing container 14
Level condition, intermittently open the water compensating valve of itself outfit, extraneous raw water allowed to enter sealing container 14 by water supply loop；
Then evaporation-condensation device, purified water output loop and lubrication oil circulation loop starts, i.e. solenoid valve b17
It opens, heater 6, water circulating pump 8, peristaltic pump a15 and peristaltic pump c39 start, and wherein heater 6 is by way of discontinuous operation
Water temperature in sealing container 14 is controlled near setting value.When temperature sensor a34 detects the water temperature in sealing container 14
When reaching setting value, vapour compression machine 11 is started to work.
Last concentrate discharge loop starts, concentrate discharge circuit is available there are two types of operating mode, that is, connects
When continuous operating mode and discontinuous operation pattern, wherein continuous operation mode refer to system work, solenoid valve d26 is normally opened, peristaltic pump b27
Continuous firing continuously discharges concentrate；After discontinuous operation pattern refers to system work, when the water purification and input that sealing container 14 exports
Raw water ratio when reaching design value, solenoid valve d26 is opened, peristaltic pump b27 starts, and the concentrate in sealing container 14 is complete
Portion excludes, and then solenoid valve d26 and peristaltic pump b27 is closed, and water supply loop starts beginning, and into sealing container 14, supplement is former again
Expect water.
When above system works, there are following control logics：
When the measured value of pressure sensor a34 is higher than setting value, vacuum pump 37 starts first, and then solenoid valve f36 is beaten
It opens；When the measured value of pressure sensor a34 is less than setting value, solenoid valve f36 is first closed, and then vacuum pump 37 is shut down.
When the measured value of pressure sensor b44 is higher than one constant of measured value of pressure sensor a34, vacuum pump 37 opens
Dynamic, then solenoid valve g45 is opened；When the measured value of pressure sensor b44 is less than one constant of pressure sensor a34 measured values
When, solenoid valve g45 is closed, and then vacuum pump 37 is shut down.
When the water temperature test value of temperature sensor 7 is less than setting value, heater 6 is started to work；When temperature sensor 7
When water temperature test value is higher than setting value, heater 6 is stopped.
When the test of fluid level controller 5 to the raw water in sealing container 14 is low liquid level, the moisturizing in fluid level controller
Valve automatically opens, and water supply loop starts to sealing container moisturizing；When the test of fluid level controller 5 to the raw water in sealing container 14
During for high liquid level, the water compensating valve in fluid level controller 5 is automatically closed, and water supply loop stops moisturizing.
When it is high liquid level that liquid level sensor a23, which detects the water of clear water tanks 21, system is so equipment is stopped；When net
When liquid level sensor a23 in water tank becomes low liquid level, system restarting is started to work.
When operating personnel, which observe, apparent liquid water sedimentation or lubricating oil significantly muddiness occurs in lubrication oil tank 38,
Manual halt system connects external peristaltic pump in Grease relief mouth 42, then opens hand-operated valve e41, will with external peristaltic pump
The lubricating oil discharge that oil tank 38 fails is lubricated, then inputs new lubricating oil, and restart system again.
When system needs to recycle the solid matter in concentrate, hand-operated valve d29 is opened, closes hand-operated valve c28, opens hand
Dynamic valve e33 makes the concentrate that peristaltic pump b27 is discharged enter solid-liquid separator 30 and carries out separation of solid and liquid, isolated clarified solution
