Description
Technical field
The present invention relates to water-treatment technology field, particularly to a kind of industrial water conditioning system.
Background technology
At present, ultra-pure water is initially that scientific and technological circle of the U.S. in order to develop ultra pure materials, (finely make pottery by quasiconductor original paper material, nanometer
Ceramic material etc.) water produced of application distillation, deionization, reverse osmosis technology or other suitable supercritical fine techniques,
Nowadays ultra-pure water is extensively applied in the field such as biology, medicine, automobile.In this water in addition to hydrone (H20), almost without
What impurity, does not more have the Organic substances such as antibacterial, virus, chloride dioxin, does not has the mineral trace unit of needed by human body the most yet
Element, ultra-pure water is without hardness, and mouthfeel is sweeter, the most frequently referred to soft water, capable of direct drinking, it is possible to boils and drinks.Ultra-pure water, is general work
The degree that skill is extremely difficult to, if resistivity of water is more than 18M Ω * cm, is then referred to as ultra-pure water close to 18.3M Ω * cm.
Ultrapure water system refers to the production system that system completely produces from former water to ultra-pure water.General ultrapure water system be through
By multi-filtering, ion exchanges, degasification, reverse osmosis, ultraviolet, ultrafiltration, nanometer rate, and ionic adsorption filters produced ultrapure
Water.
In prior art a lot of for industrial water conditioning system, such as open (bulletin) number: CN103827040A, be used for carrying
For the method and system of ultra-pure water, by utilizing Free-radical ring opening polymerization and free radical to remove system, water is processed.Freely
Base scavenging system can utilize the actinic radiation by free radical original chemical (such as Ammonium persulfate .).Free radical removes system
The use to reducing agent can be included.By utilizing Ion Exchange Medium and depassing unit, ultra-pure water can be carried out further
Process.Control system can be utilized to adjust the interpolation of original chemical, the intensity of actinic radiation and reducing agent adding to water
Add.
The production equipment of ultra-pure water is that comparison is existing as can be seen here, for different equipment, wherein the utilization rate of water and
Pollution discharge capability all has difference, although this system can produce ultra-pure water, but this complex technical process, cost is larger, nothing
Method is popularized, and is unfavorable for promoting.
The most such as Publication No. CN101857329A, a kind of waste water circulation reuse is the process technique of industrial extra-pure water, bag
Include following steps: pretreatment, the absorption of preposition activated charcoal, first-stage reverse osmosis, post active carbon absorption, two-pass reverse osmosis and electricity go from
Son.Preposition activated charcoal can be recycled and reused for by simple operations after reverse osmosis postposition activated carbon adsorption is saturated to adsorb.The present invention
Can will be enriched in organic washing agent, the waste water of heavy metal ion is treated as the qualified ultra-pure water of TOC, and ensures that equipment is stably transported
OK, having simple, efficient, stable, the advantage of low cost, reusing rate reaches more than 60%, can be widely used for using in a large number ultrapure
The waste water that waste water processes and municipal middle water reuse is boiler of power plant make-up water of the industry such as the electronics of water, quasiconductor processes.
This system uses orthoscopic to process technique, and its water source circulation ability need to improve.

All components and parts are sealed off by the housing of envelope, use the mode of magnetic induction to carry out isolating steam and enter, safe and reliable.
It addition, see the structure chart of Fig. 1, industrial fresh water rate of water make-up is 39.54t/h, then disc filter 2 inflow is
39.54t/h, if disc filter 2 and ultrafiltration apparatus 3 flush discharge are 2.8t/h, then has the aquifer yield of 36.74 t/h to arrive
Water tank with strainer 4；Water tank with strainer 4 has the water of 1.45 t/h to get rid of to ultrafiltration apparatus 3, and has the concentrate recirculation amount of 5.87 t/h to return to
Water tank with strainer 4, water tank with strainer 4 is last by the one-level RO inflow of 41.16 t/h, and one-level RO device 5 has the one-level of 10.29 t/h
The dense water yield of RO gives dense water tank, and the denseest water tank can provide 4.22 t/h to be used as alternate source to ultrafiltration apparatus 3 and disc filter
2；By intermediate water tank 6, two grades of RO inflow 30.87 t/h being delivered to two grades of RO devices 7, two grades of RO devices 7 have 3.09t/h
Two grades of RO concentrate recirculations get rid of, two grades of RO devices 7 have two grades of RO aquifer yields of 27.78t/h in RO fresh-water tank 8, EDI device
9 have the EDI concentrate recirculation of 2.78t/h to export, so last EDI device 9 has 25t/h aquifer yield to deliver to sweet-water tank 10, so,
Can draw from circulation above, the Water Sproading rate of system reaches 25/39.54=63.23%.
EDI device 9 discharges without spent acid salkali waste, and the water use efficiency of itself reaches as high as 98%.Use the YYRO-30T in benefit source
Equipment.
A kind of anti-cleaning method of industrial water conditioning system.Mainly ultrafiltration apparatus 3 is carried out.
Step 1: acid cleaning, adds hydrochloric acid mass fraction 1.8%, medicinal liquid consumption 1000L, and following current is straight-through cleans；
Step 2: alkalescence is cleaned, adds sodium hydroxide mass fraction 1%, medicinal liquid consumption 1000L, wash cycles and following current straight-through clear
Wash；
Step 3: sterilizing, ultra violet lamp, continues to use wash cycles and the straight-through cleaning of following current.
Wherein, following current is led directly to cleaning and is included: a1, cleaning pressure: 0.1-0.15Mpa, 2 times repeatedly；A2, flushing pressure:
0.25 Mpa, rinses 0.5 hour；
Wash cycles includes: a1, cleaning pressure: 0.1-0.15Mpa, circulates 25 minutes.
By above-mentioned cleaning method, the Data Comparison table before and after it cleans is as follows:
| Ultrafiltration apparatus parameter | Before cleaning | After cleaning |
| Intake pressure/MPa | 0.35 | 0.33 |
| Produce water pressure/MPa | 0.21 | 0.21 |
| Dense entrance pressure power/MPa | 0.18 | 0.18 |
| Dense go out pressure/MPa | 0.14 | 0.14 |
| Produce discharge/(m/h) | 20.3 | 24.1 |
| Concentrated water discharge/(m/h) | 0.85 | 0.90 |
| Pole water emission flow/(m/h) | 0.82 | 0.86 |
| Produce water resistance rate/(M Ω * cm) | 16.8 | 17.7 |
| Voltage/V | 60 | 60 |
| Electric current/A | 17.9 | 18.0 |
It follows that before and after cleaning, crucial cleaning index does not the most occur significantly to change, cleaning performance is more preferable, right
After cleaning, the resistivity of producing water ratio increases, and the operating current of EDI improves, and effluent quality is more preferable, and electric current is relatively low,
Device desalting ability is then made to reduce relevant.
This specific embodiment is only explanation of the invention, and it is not limitation of the present invention, people in the art
The present embodiment can be made after reading this specification by member as required does not has the amendment of creative contribution, but as long as at this
All protected by Patent Law in the right of invention.
