Description
Technical field
The invention belongs to reverse osmosis unit technical field, more particularly, it relates to a kind of real estate water yield perseverance response rate is stable
The counter-infiltration system controlling.
Background technology
The basic functional principle of reverse osmosiss is：With high-pressure hydraulic pump, after raw water is added to, make a part of raw water in pressure
Reverse osmosis membrane is penetrated under effect.Chemical ion and antibacterial, funguses, virion can not be passed through, and discharge with concentrated water.Reverse osmosis unit
In running, its operating flux, pressure, the response rate can change with the factor change such as water inlet water temperature, water quality.And with
The contaminated situation of counter-infiltration system itself, operating flux, pressure, the response rate also can change.Its change under normal circumstances
Situation is：When the temperature increases, aquifer yield raises, counter-infiltration system operating pressure reduces, the response rate raises.When water inlet salinity
During rising, counter-infiltration system aquifer yield reduces, operating pressure raises, the response rate raises.When reverse osmosis membrane blocking aggravation, produce water
Amount reduces, operating pressure raises, the response rate is possible to rising and is also possible to reduce.
When designing counter-infiltration system, designer requires according to influent quality, producing water water quality, the class of in-line coagulation
The suitable response rate of the selecting factors such as type, the kind of the antisludging agent adding.Select the suitable response rate, can be effectively sharp
With water resource, can effectively prevent organic fouling and the inorganic scaling on film surface simultaneously again；As the response rate selects too low, then water money
Source is discharged by concentrated water side, causes to waste；As the response rate selects too high, inorganic salt and Organic substance, easily in film surface scale, are led
The cleaning frequency causing film increases, and the service life of film shortens, and operating cost increases.The suitable response rate is therefore selected to be to weigh very much
Want.In sum, in the day-to-day operation of counter-infiltration system, the response rate of real-time control counter-infiltration system is in normal design value
Seem particularly significant.
Aquifer yield with regard to counter-infiltration system generally to be determined by the demand of reverse osmosis produced water, and counter-infiltration system exists
Also a normal aquifer yield scope is had during design.For a set of reverse osmosis to be normally designed according to aquifer yield demand
For permeable system, it not only matches with counter-infiltration system urban water demand, and the aquifer yield of its own just also necessarily be in simultaneously
Often aquifer yield scope.But in actual moving process, the aquifer yield of counter-infiltration system often can be because the temperature of its water inlet, water quality become
Change and film self-pollution situation changes and produces change.When counter-infiltration system aquifer yield raises, the dirt of counter-infiltration system is blocked up
Speed may increase, and service life may shorten；And use discharge, reverse osmosis because counter-infiltration system water acquisition flow is more than
Permeable system will frequent start-stop, thus can lead to counter-infiltration system recycled in its entirety rate reduce, specific yield operating cost increase,
Simultaneously because frequent shutdown can cause the dirty stifled probability of reverse osmosis membrane to increase, reduce the service life of reverse osmosis membrane.And work as reverse osmosiss
When system aquifer yield reduces, the problem of the maximum of generation is system aquifer yield deficiency it is impossible to meet water demand；Therefore control anti-
The aquifer yield of osmosis system seems particularly significant in normal design value.
But, also the aquifer yield and the response rate of counter-infiltration system is not entered in the design of existing counter-infiltration system simultaneously
The design that the row real estate water yield is controlled with the permanent response rate.If Chinese Patent Application No. is 200920191682.3, Granted publication
Day is that the patent document of on 05 19th, 2010 discloses a kind of Anti-permeation constant flow control system, the control system in this patent
System is than more conventional design control method.Its principle is to produce water in counter-infiltration system to install effusion meter, using counter-infiltration system
Produce discharge and reverse osmosis high-pressure pump operation frequency is controlled and then reaches with the purpose that counter-infiltration system produces water constant flow, but should
There is certain defect in the control method of design.Its startup optimization curve is often as shown in Figure 2.Every time due to being during system start-up
System internal pressure is relatively low, and water pump operation frequency can accelerate to higher running frequency always, and meanwhile, the flow of inlet water of system also can be with
Water pump operation frequency rises and steeply rises；And the cushioning effect due to counter-infiltration system itself, raising speed on the pressure in system
The speed that degree rises with respect to water pump operation frequency and flow of inlet water has postponed, and the actual product discharge of counter-infiltration system is relatively
Can there is certain delay in the operating pressure in counter-infiltration system again.Until the reverse osmosis produced water yield rises to normal aquifer yield,
Reverse osmosis high-pressure pump operation frequency, reverse osmosiss operating pressure already far beyond normal operating value, and in subsequent mediation process
The operating pressure of middle water pump frequency system, flow can be less than towards reverse osmosis high-pressure pump operation frequency, reverse osmosiss operating pressure again
The direction of normal operating value is run.System can moving closer to normal operating value in parameters after repeatedly repeatedly adjusting,
But may all can not adjust stable all the time completely.Therefore, as previously described, using effusion meter being used for is installed on water producing pipe road
In the mistake all inherently experiencing an altofrequency, high pressure, super flow when the counter-infiltration system of real estate water rate control starts every time
Journey, and it is stable also to would become hard to adjustment in system normal course of operation.
