Technical field
The invention patent belongs to water-treatment technology field, especially in reverse osmosis nanofiltration membrane system applied technical field.
Background technique
Reverse osmosis nanofiltration is by development in recent years, and technology reaches its maturity, but reverse osmosis nanofiltration membrane system is in work
Often have that instrument detection error, monitoring be inaccurate, correction runs shape to system caused by problems not in time etc. in journey example
The false judgment of condition is often misled due to false assessment system because false judgment causes to give misleading.
Currently, the measuring instrument of almost all of reverse osmosis nanofiltration system has into water conductivity meter, produces Water Conductance Instrument, production
Water flowmeter, concentrated water flowmeter, by " production water flowmeter numerical value/（Produce water flowmeter numerical value+concentrated water flowmeter numerical value）*100%"
The rate of recovery for obtaining system, by "（1- produces Water Conductance Instrument numerical value/water inlet conductivity meter numerical value）* 100% " the de- of system is obtained
Salt rate.
The numerical value that current conductivity meters many on the market and flowmeter are monitored after for a period of time often exists and actual number
Value has certain deviation, and instrument needs regular calibration, and such as correction frequently can lead to system operatio or administrative staff to being not in time
System erroneous judgement and the guidance of mistake.
Summary of the invention
The present invention aiming at the shortcomings of the prior art, to overcome current reverse osmosis nanofiltration above shortcomings, proposes one kind
Novel reverse osmosis nanofiltration membrane system monitoring technology, it is therefore an objective to improve reverse osmosis nanofiltration membrane system monitoring accuracy, in time warning system
System monitors existing deviation, corrects in time convenient for system operatio or administrative staff, more accurately monitors the operating parameter of system, more
Prepare the operation conditions of control system, it is ensured that system monitoring error is in allowed band.
To achieve the above object, the present invention is achieved through the following technical solutions：
A kind of reverse osmosis nanofiltration system monitoring deviation prompts technology in time, including conductivity meter, reverse osmosis nanofiltration system, produces water power
Electrical conductivity instrument, feed water flow scale, concentrated water conductivity meter, concentrated water flowmeter.On the water inlet conductivity meter installation system inlet pipeline,
The reverse osmosis nanofiltration system water inlet is connect by pipeline with water inlet conductivity meter, the production Water Conductance Instrument, water inlet
Flowmeter is mounted on system water producing pipe road, produces the mouth of a river with reverse osmosis nanofiltration system by pipeline and connect, the concentrated water conductance

Row maintenance and personal management.
Detailed description of the invention
Below according to attached drawing, invention is further described in detail.
Fig. 1 is that the present invention is applied to reverse osmosis nanofiltration processing technology field process flow chart.
In attached drawing：
1, water inlet conductivity meter, 2, reverse osmosis nanofiltration system, 3, production Water Conductance Instrument, 4, feed water flow scale, 5, concentrated water conductivity
Instrument, 6, concentrated water flowmeter.
Specific embodiment
To illustrate that the present invention, implementation column of the present invention are as follows in more detail：
As shown in the picture, a kind of reverse osmosis nanofiltration system monitoring deviation described in present example prompts technology, including water inlet in time
Conductivity meter（1）, reverse osmosis nanofiltration system（2）, produce Water Conductance Instrument（3）, feed water flow scale（4）, concentrated water conductivity meter（5）,
Concentrated water flowmeter（6）.The water inlet conductivity meter（1）On installation system inlet pipeline, the reverse osmosis nanofiltration system（2）Into
The mouth of a river passes through pipeline and water inlet conductivity meter（1）Connection, the production Water Conductance Instrument（3）, feed water flow scale（4）It is mounted on and is
Water producing pipe unite on the road, passes through pipeline and reverse osmosis nanofiltration system（2）Produce mouth of a river connection, the concentrated water conductivity meter（5）, concentrated water
Flowmeter（6）It is mounted on system concentrated water pipeline, passes through pipeline and reverse osmosis nanofiltration system（2）Concentrated water spout connection.
When specifically used：
Be lifted into reverse osmosis nanofiltration system water inlet of the raw water by power-equipment, reverse osmosis nanofiltration system the production mouth of a river, concentrated water
Respectively by piping connection to mutually using water spot, drainage point or storing spot.Water inlet conductivity meter is mounted on reverse osmosis nanofiltration system
On inlet pipeline, Water Conductance Instrument is produced, feed water flow scale is mounted on reverse osmosis nanofiltration system water producing pipe road, concentrated water conductivity
Instrument, concentrated water flowmeter are mounted on reverse osmosis nanofiltration system concentrated water pipeline.
Wherein：
C into=water inlet conductivity value
C produces=produces water conductivity value
C is dense=concentrated water conductivity value
Q produces=produce water flow value
Q is dense=concentrated water flow value
The Y1 system rate of recovery=Q production/(Q production+Q is dense) * 100%
The Y2 correction rate of recovery=（Dense-the C of C into）/ (dense-C of C is produced) * 100%
P deviation=（The 1- Y1 system rate of recovery/Y2 corrects the rate of recovery）* 100%=1- [Q produces/(Q production+Q is dense)]/[（C is dense-
C into）/ (dense-C of C is produced)] } * 100%
The above numerical value C passes through instrument monitoring into, C is produced, C is dense, Q is produced, Q is dense, and the Y1 system rate of recovery, Y2 correct the rate of recovery, P deviation
It is acquired by formula calculating.
By setting P deviation（Such as A%, can be set as needed）.
Such as-A% < P deviation < A%；Then system is normal, and each monitoring index error is in allowed band.
P deviation >=A% or P deviation≤- A%；Then system exception, monitoring index error exceed allowed band, need to stand
Correct.
Any drug such as reducing agent or antisludging agent or foreign ion or substance are not added in this system, if any addition reducing agent
Or the substances such as antisludging agent, then conductivity meter of intaking are mounted on after drug adds.
Specific embodiments of the present invention are described above, it is more specific and detailed, but should not be understood as to this hair
The limitation of bright the scope of the patents.It should be pointed out that not departing from structure of the invention for the general technical staff of this field
Under the premise of think of, various modifications and improvements can be made, these belong to the scope of protection of the patent of the present invention, therefore, this hair
The protection scope of bright patent is determined by the appended claims.
