Technical field
The utility model relates to the equipment, particularly laboratory usefulness of preparation pure water and ultrapure water, adopts reverse osmosis technology and ion exchange technique to produce the ultrapure water machine of pure water and ultrapure water.
Background technology
At present, in laboratory and industrial ultrapure water machine, most of ultrapure water machine all is to adopt single pump single-stage osmosis filtration mode.But up to now, also not having a kind of machine on the market is to adopt single pump twin-stage reverse osmosis system.
The utility model content
The purpose of the utility model provides a kind of single pump twin-stage r-o-ultrapure water machine, makes machine water quality better, and the replacing frequency of consumptive material reduces.
The technical scheme of the utility model is following:
A kind of single pump twin-stage r-o-ultrapure water machine; Include entering water electromagnetic valve, topping-up pump, first-stage reverse osmosis device, two-pass reverse osmosis device, flush valve, waste water proportional valve and ion-exchanger; It is characterized in that: described entering water electromagnetic valve, topping-up pump, first-stage reverse osmosis device, two-pass reverse osmosis device and ion-exchanger are in series through pipeline successively; The wastewater outlet of said first-stage reverse osmosis device and two-pass reverse osmosis device connects the waste water proportional valve after being in series through pipeline, a side bypass flush valve of said waste water proportional valve.
Described single pump twin-stage r-o-ultrapure water machine, it is characterized in that: described topping-up pump is the voltage stabilizing topping-up pump.
Described single pump twin-stage r-o-ultrapure water machine, it is characterized in that: said topping-up pump top hole pressure is 0.56MPa, the operating pressure of first-stage reverse osmosis device, two-pass reverse osmosis device is 0.4Mpa.
Described single pump twin-stage r-o-ultrapure water machine, it is characterized in that: said first-stage reverse osmosis device, two-pass reverse osmosis device all adopt the ultralow pressure reverse osmosis membrane.
Described single pump twin-stage r-o-ultrapure water machine, it is characterized in that: described pipeline is 2 fens PE water pipes.
This novel main configuration flow is: tap water is through the pretreater coarse filtration; Exert pressure by topping-up pump again; Let water advance the first-stage reverse osmosis device, the product water of first-stage reverse osmosis device advances the two-pass reverse osmosis device again, lets its deep desalting; Reach request for utilization again through ion-exchanger, reach the ultrapure water requirement through aftertreatment more at last.
This novel employing voltage stabilizing topping-up pump (DP782414) top hole pressure reaches 0.56MPa; The operating pressure of counter-osmosis device reverse osmosis membrane is about 0.4MPa; Average ratio of desalinization is 98%, leads like the source water power to be 400us/cm, and the product water of first-stage reverse osmosis (300G) just should be 8us/cm; Can not reach three grades of water requirements of the water GB/T6682-2008 of National Laboratory (≤5us/cm); Pass through two-pass reverse osmosis (100G) filtration filter again as producing one-level in water, produce water, reach three grades of water water quality standards just fully less than 5us/cm.By the relatively poor north of water quality is example, is 1500us/cm like source water, and the product water of first-stage reverse osmosis (300G) should be 30us/cm, passes through two-pass reverse osmosis (100G) again and also can reach the three grades of water quality standards in laboratory.
The beneficial effect of the utility model:
(1), the utility model makes the pure water of machine can reach three grades of water quality standards of National Laboratory, satisfies more requirement of experiment;
(2), the utility model can prolong ion-exchanger work-ing life; It is less than 10us/cm that the theory water inlet of ion-exchanger requires; Yet this requirement can not be satisfied in the relatively poor place of water quality; The exchange capacity of ion-exchanger is just had a greatly reduced quality, and this novel pure water can strengthen the exchange capacity of ion-exchanger less than 5 us/cm;
(3), the twin-stage counter-osmosis device of the utility model all adopts single pump type, reduced the use power of machine, also can not account for the machine intimate more space simultaneously.
Description of drawings
Fig. 1 is the utility model structural principle block diagram.
Fig. 2 is the utility model structural representation.
Embodiment
Referring to Fig. 1,2; A kind of single pump twin-stage r-o-ultrapure water machine; Include entering water electromagnetic valve 1, topping-up pump 2, first-stage reverse osmosis device 3, two-pass reverse osmosis device 4, flush valve 5, waste water proportional valve 6 and ion-exchanger 7; Entering water electromagnetic valve 1, topping-up pump 2, first-stage reverse osmosis device 3, two-pass reverse osmosis device 4 and ion-exchanger 7 are in series through pipeline 8 successively; After being in series through pipeline, the wastewater outlet of first-stage reverse osmosis device 3 and two-pass reverse osmosis device 4 connects waste water proportional valve 6, a side bypass flush valve 5 of waste water proportional valve 6; Pipeline 8 adopts 2 fens PE water pipes.
Topping-up pump 2 is the voltage stabilizing topping-up pump, can remain on 0.56Mpa to water feeding pressure (0.1-0.4) MPa always.
