It crosses after water pump heats the water in finished product water tank 51 by electric heater 53 and refills to finished product water tank 51, then pass through finished product
Water tank 51 provides warm water to feed water inlet 14；And by feed water inlet 14, waterpipe 16, water return pipeline 16 will be returned once with water lines
Water is sent to the entrance of the first ultraviolet sterilizer 52, is injected in finished product water tank 51 after being sterilized again, is moved up water transport.
When needing to clean system, the first step cleans route by CIP and carries out CIP cleaning, passes through the first cleaning
Pipeline 17 is added CIP cleaning solution and is passed through to preposition water tank 101, passes sequentially through the first connecting pipe 7, active carbon filter later
21, the second connecting pipe 8, the first cartridge filter 22, third connecting pipe 9, the second ultraviolet sterilizer 23, the 4th connecting pipe
10, it is discharged after ultrafilter 31, the 5th connecting pipe 11, nanofiltration device 41, finished product water tank 51；Wherein, when only to preposition water tank 101 with
And active carbon filter 21 is directly drained from active carbon filter 21 when being cleaned；When only being carried out clearly to ultrafilter 31
When washing, CIP cleaning solution is input to by the 5th connecting pipe 11 by the first cleaning pipeline 17 and the second cleaning pipeline 18, is passed through
5th connecting pipe 11 reversely send CIP cleaning solution to being cleaned in ultrafilter 31 to it；When only to the progress of finished product water tank 51
When cleaning, CIP cleaning solution is passed through into finished product water tank 51 by the first cleaning pipeline 17, is discharged later；Second step passes through
Clear water backwash lines are washed, by the first backwash pipeline 20 of 51 bottom of finished product water tank by pure water send at modules into
Row cleaning, wherein the first backwash pipeline 20 cleans pipeline 17 with heating pipe 55, first and the second cleaning pipeline 18 shares one
Pipeline；Since in water-washing process, nanofiltration device 41 does not need to clean, therefore nanofiltration device 41 is connected to from the outlet of ultrafilter 31 and is exported
The second backwash pipeline 19 get around nanofiltration device 41, can also directly be drained on the second backwash pipeline 19.
To sum up, by above system, the function of supply cold water and hot water is realized, while directly being passed through and real with pipeline
Existing CIP cleaning and the effect with water backwash, no dead angle and ponding；The system treated water can be sanitation-grade direct drinking, protect
The mineral element that calcium and magnesium is beneficial to human body has been stayed, stagnant water is not had, has improved water quality.
It is emphasized that: the above is only presently preferred embodiments of the present invention, not make in any form to the present invention
Limitation, any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention,
All of which are still within the scope of the technical scheme of the invention.
