Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
A kind of NF membrane TDS regulating system as shown in Figure 1, the filter membrane group be formed in parallel by DF90 film 4 and DF30 film 8, total water inlet is connected with the water inlet end of DF90 film 4 with DF30 film 8 respectively by adjustable three-way valve 1, by adjusting adjustable three-way valve 1, controls the inflow of two filter membranes; After its product water end (W.E.) converges, as total product water of water purifier, dense water end (W.E.) is respectively equipped with the dense water valve of DF90 film 5 and the dense water valve 7 of DF30 film, by adjusting dense water valve (5,7), controls the waste water ratio of two filter membranes.With regard to connecting line, running water water inlet pipe is connected with PE flexible pipe 3 by adjustable three-way valve 1, and for ensureing that pipe interface is water-tight further, the bending place of flexible pipe 3 is provided with elbow 2, produces water meet and is provided with threeway 6.
The Principles of Regulation of producing water TDS value are:
Given one can ensure that target produces the original state of water TDS value; When producing water TDS value and rising, regulate the water amount of leading to DF90 film 4 and DF30 film 8 two ends, different TDS is produced water and mixes according to different ratios, make always to produce water demineralizing rate and remain at 60% ~ 70% for ideal range.
Above-mentioned NF membrane regulating system is applied to Domestic water filter, and concrete operations are:
First, first open adjustable three-way valve 1, the pipeline of film periphery is kept clear; Afterwards:
I) original state: regulate the dense water valve of DF90 film 5 and the dense water valve 7 of DF30 film, it is made all to open 1/3, now will always produce the test of water TDS value after system cloud gray model 30min, test result is calculated real-time salt rejection rate according to salt rejection rate computing formula, wherein: salt rejection rate=(1-always produces the TDS of the TDS/ running water of water) × 100%, if salt rejection rate meets the requirement of 60% ~ 70%, then judge now always to produce water TDS value better; If not, then regulate:
Ii) adjustment state: start adjustable three-way valve 1 (as rotated the spanner of adjustable three-way valve 1, or regulate adjustable three-way valve in real time by the mode automatically controlled), regulate the water amount of leading to DF90 film 4 and DF30 film 8 two ends, by the filter effect of two film, different TDS is produced water mix according to different ratios, the total TDS value of producing water of adjustment, finally realizes the ideal range that salt rejection rate controls 60% ~ 70%; Particularly:
1) if salt rejection rate is less than 60%, then judge that the TDS value of now always producing water is higher, need to regulate adjustable three-way valve 1, keep the inflow of DF90 film 4 constant, the inflow of DF30 film 8 is reduced, the aquifer yield of DF30 film 8 decreases, and the product water mixed proportion reducing higher TDS value is adjusted to and meets the requirements;
2) if salt rejection rate is greater than 70%, then judge now always to produce water TDS value lower, need to regulate adjustable three-way valve 1, keep the inflow of DF30 film 8 constant, the inflow of DF90 film 4 is reduced, the aquifer yield of DF90 film 4 decreases, and the product water mixed proportion reducing lower TDS value is adjusted to and meets the requirements;
Along with the growth of system operation time, water amount can increase naturally, by the impact of DF90 film 4 with self service life of DF30 film 8, even if under identical ratio, total product water TDS value is follow-up also can there are some changes, thus, along with running time increases, according to real-time total product water TDS value, need regulate in real time according to aforesaid operations method, guarantee that salt rejection rate remains in 60 ~ 70% scopes, make always to produce water TDS value and be in normal level, ensure that total water that produces both had been heated up water non-scaling, the mineral matter of needed by human body can be kept again here, really realize substituting RO membranous system.
Can find out, NF membrane TDS regulating system of the present utility model adopts control valve to control two film (DF90 and DF30 membrane component) water inlet and the mode of producing discharge, produce water mixing by two film and regulate product water TDS value, two film separately flow of inlet water is adjustable, when self aquifer yield of two film is substantially identical, by regulating two film inflow to control two film aquifer yield, ensure that product water quality.
Why will ensure that the salt rejection rate of two filter membranes is distinguished to some extent, be to ensure by regulating respective inflow can improve total product water demineralizing rate.In addition, in actual applications, be also not only two filter membranes, according to the requirement of degree of regulation, also can extend to the filter membrane group of some Zhi Binglian, often prop up in filter membrane group and can be combined by the mode of some filter membranes series connection and/or parallel connection again.
Below explain embodiment of the present utility model by reference to the accompanying drawings, accompanying drawing is herein used to provide further understanding of the present utility model.Obviously; the foregoing is only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any be to one skilled in the art can expect easily, do not depart from change of the present utility model or replacement in fact, be also all included within protection domain of the present utility model.
