Description
Technical field
The utility model, which belongs to, prepares ultra-pure water technical field, more particularly to a kind of ultrapure water preparation device.
Background technology
Pure water is also known as pure water, refer to meet the water of standards for drinking water quality as raw water, by electric dialyzator method,
Ion-exchanger method, hyperfiltration, the way of distillation and its processing method appropriate, obtained pure water are sealed in container, and are free of and are appointed
What additive, water white transparency, water capable of direct drinking, space water, the distilled water sold in the market belong to pure water.
Ultra-pure water be further the conducting medium in water is almost removed on the basis of pure water, and by water not from
Colloidal substance, gas and the organic matter of solution are removed to the water of very low degree, and resistivity is more than 18M Ω/CM, or close to 18.25M
Ω/CM limiting values；Ultra-pure water is the degree that general technology is extremely difficult to, can be by micro-filter technology, hyperfiltration technique, reverse osmosis skill
Art, EDI technologies, two kinds or more of technology in ion exchange technique, by rational technological design, lectotype selection can
Ultra-pure water at manufacture, and it is stringenter in requirement of the field of medicaments to ultra-pure water.
But the process equipment used in the prior art is most of all using softening plus reverse osmosis such technique, leads in this way
Cause is only capable of removing a part of salinity and other impurities in water, it is desirable to obtain ultra-pure water that high quality is up to state standards also far from
It is enough, it is therefore desirable to propose a kind of scheme to solve the problems, such as this.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of ultra-pure water preparation dress
It sets.
To achieve the goals above, the utility model is realized using following technical scheme：
A kind of ultrapure water preparation device, including sequentially connected raw water box, quartz filter, the first cartridge filter,
Water tank with strainer, first-stage reverse osmosis system, pure water tank, two-stage reverse osmosis system, EDI systems and the smart mixed bed of polishing.
Further, it is provided with raw water pump between the raw water box and the quartz filter.
Further, it is provided with high-pressure pump between the water tank with strainer and the first-stage reverse osmosis system.

The utility model has the beneficial effects that：
A kind of ultrapure water preparation device provided by the utility model, first-stage reverse osmosis system and two-stage reverse osmosis system it
Before, quartz filter is set and first security personnel's filter ensures equipment as pretreatment system to ensure system run all right
Stable operation reliably and with long-term and producing water water quality are stablized；Setting first-stage reverse osmosis system and two-stage reverse osmosis system it can stop it is all
Dissolubility salt and relative molecular mass are more than the organic matter of 100 dalton, but hydrone is allowed to penetrate, reverse osmosis composite membrane desalination
Rate is generally higher than 98%, and the smart mixed bed of setting polishing swaps the various ions in fluid, removes.

Specific implementation mode
To keep the purpose of this utility model, feature, advantage more apparent and understandable, with reference to the utility model
Attached drawing in embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that institute below
The embodiment of description is only the utility model a part of the embodiment, and not all embodiments.Based on the reality in the utility model
Example is applied, the every other embodiment that those skilled in the art is obtained shall fall within the protection scope of the present invention.
The present embodiment provides a kind of ultrapure water preparation devices, as shown in Figure 1, including sequentially connected raw water box 1, quartz sand
Filter 3, the first cartridge filter 4, water tank with strainer 5, first-stage reverse osmosis system 7, pure water tank 8, two-stage reverse osmosis system 10,
EDI systems 12 and polishing essence mixed bed 13.
One as the present embodiment is preferably provided with raw water pump 2 between raw water box 1 and quartz filter 3.
One as the present embodiment is preferably provided with high-pressure pump 6 between water tank with strainer 5 and first-stage reverse osmosis system 7.
One as the present embodiment is preferably provided with pure water pump 9 between pure water tank 8 and two-stage reverse osmosis system 10.
Quartz filter 3 and first is set and ensures public security filter 4 as pretreatment system, pretreatment main purpose is that removal is former
Suspended matter, colloid, coloration, turbidity, organic matter in water etc. interfere the impurity of subsequent technique system normal operation.
Quartz filter 3, as filler, removes the impurity in water removal using quartz sand.Setting filter in quartz filter 3
Material and filter body, realize the self-adapting operation of filter body, filtrate is to influent density, operating condition, pretreatment technique
Deng have very strong adaptivity, i.e., filtering when filter body automatically form it is upper dredge under close state, be conducive in various operations
Under the conditions of ensure effluent quality, filtrate fully scatters when backwash, and cleaning performance is good.Quartz filter 3 can effectively remove in water
Suspended matter, and there is apparent removal to act on the pollutants such as colloid, iron, organic matter, pesticide, manganese, bacterium, virus in water.
First-stage reverse osmosis system 7 and two-stage reverse osmosis system 10 are a kind of embrane method liquid separation technologies of precision, it can be hindered
It keeps off all dissolubility salt and relative molecular mass is more than the organic matter of 100 dalton, but hydrone is allowed to penetrate, it is reverse osmosis compound
Film salt rejection rate is generally higher than 98%.They are widely used in seawater and brackish water desalination, and boiler feedwater, industrial pure water and electron level are super
Pure water preparation, the processes such as drinking pure water production, wastewater treatment and special separation.
The smart mixed bed 13 of polishing is exactly that a certain proportion of cationic, anionic exchange resin is mixed loaded in same switch
In, the various ions in fluid are swapped, are removed.Hydrogen type cation exchange resin is used to remove the cation in water；Hydrogen
Oxygen type anion exchange resin is used to remove the anion in water.Since the density of positive resin is usually bigger than negative resin density, institute
With general negative resin is above in mixed bed, and positive resin is below.The ratio of positive and negative resin filling is 12, also there is filling ratio
Example is 115, can take the circumstances into consideration to consider selection by different resins.This system uses synchronizing regeneration formula mixed bed, runs and entirely regenerated
Cheng Jun is carried out in mixed bed, and resin need not remove other than equipment when regeneration, and positive and negative resin regenerates simultaneously, therefore required attached
It is few to belong to equipment, it is easy to operate.This experiment uses polishing resin to the further advanced treating of prime ED I ultra-pure waters, to ensure terminal
Water outlet reaches quality requirement.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but not to this practicality newly
The limitation of type protection domain, those skilled in the art should understand that, based on the technical solution of the present invention, ability
Field technique personnel need not make the creative labor the various modifications or changes that can be made still in the protection model of the utility model
In enclosing.
