Stream direction is sequentially provided with flowmeter, conductivity gauge, pressure gauge and pressure difference switch.It is anti-that the water that second high-pressure pump 11 is extruded enters the second level
Permeability apparatus 12, is provided with flowmeter, conductivity gauge and pressure difference switch after second level reverse osmosis unit 12.Jing second level counter-infiltration dress
After putting 12 process, remaining the first return lines of water Jing 16 flow back into water tank, it is also possible to any bit flowing back in pretreatment module
Put.Current excess of imports pure water tank 15 Jing after the process of EDI modules 14, is provided with flow on the pipeline between EDI and ultrapure water tank 15
Meter and conductivity gauge, Jing after EDI process, remaining the second return lines of water Jing 17 flow back into raw water box 1, it is also possible to flow back into pre- place
Any position in reason module.
Why first order reverse osmosis unit 10 adopts two reverse osmosis membrane assemblies in parallel, is because such as reverse osmosis above
Permeable membrane because the reason such as pressure instability, breakage, blocking or fouling is destroyed, will soon cause reverse osmosis membrane below with
EDI modules 14 are destroyed.Two reverse osmosis membrane assemblies in parallel are adopted in first order reverse osmosis unit 10, one is acted primarily as and is delayed
Punching is acted on.If on the one hand a reverse osmosis membrane assembly is broken, the electrical conductivity below of first order reverse osmosis unit 10 can be caused to occur
Change, Jing conductivity gauges are detected, it is possible thereby to rapidly fix a breakdown；If on the other hand a reverse osmosis membrane assembly is broken, also
There is an energy normal work, very big impact will not be caused to rear production.It should be noted that the present invention adopts two, this area
Technical staff can be extended as needed, using the reverse osmosis that two or more is in parallel such as in first order reverse osmosis membrane apparatus
Permeable membrane component.
The present invention is at the system failure by the first order reverse osmosis unit 10 of two counter-infiltration membrane module compositions in parallel
Reason provides a buffer time, and in handling failure, system can also be run, and thereby ensure that the stability of system.By many
Increase on medium filter 3, active carbon filter 4 and softening filter 5 and automatically control 18 and realize itself clean, extend
The service life of pretreatment system.By the first return line 16 is set after the second reverse osmosis unit, is set after EDI modules 14
Two return lines 17, remaining water backflow after the second reverse osmosis unit and EDI modules 14 are processed improve water utilization rate.
In one embodiment of the invention, the production procedure of the ultra-pure water process units is specially：Raw water is by original
Water pump continuously enters the first filter mechanism, the second filter mechanism and the 3rd filter after milipore filter carries out first time filtration
Structure, first filter mechanism, the second filter mechanism and the 3rd filter mechanism are controlled by Full-automatic flushing valve, Neng Goushi
Now backwash, the purpose of backwash is, in order to wash away the filter residue remained in filter mechanism, to make filter medium in filter mechanism again
It is raw.There is the salting liquid containing potassium, sodium ion in salt box in addition, for living again to the medium of the 3rd filter mechanism.Pass through
Pretreated raw water enters cartridge filter, Jing after cartridge filter removing turbidity is more than 1 particle, is entered by high-pressure pump
Entering reverse osmosis unit carries out osmosis filtration, and less than after preset value, water is separated detection electrical conductivity into EDI modules,
Pole water, concentrated water and fresh water separate, and pole water and concentrated water enter wastewater treatment equipment by the second return line, and fresh water passes through resistivity
It is up to standard after detection, obtain ultra-pure water.
The above is only the preferred embodiment of the present invention, it is noted that it is right that above-mentioned preferred embodiment is not construed as
The restriction of the present invention, protection scope of the present invention should be defined by claim limited range.For the art
For those of ordinary skill, without departing from the spirit and scope of the present invention, some improvements and modifications can also be made, these change
Enter and retouch also to should be regarded as protection scope of the present invention.
