Description
Technical field
The utility model relates to a kind of reverse osmosis concentrated water recovery devices in purified water preparation process.
Background technique
In conventional purification water preparation process, it is even more that reverse osmosis produced water and discharge of wastewater ratio reach 1:3, and wherein big
Effluent part comes from reverse osmosis link concentrated water discharge, and concentrated water direct emission will cause the waste of water resource, and be introduced directly into softening
Water reprocessing can improve reverse osmosis operation burden again, reduce lifetime of system.
Utility model content
The utility model aim be provide in view of the defects existing in the prior art it is a kind of in purified water preparation process
Reverse osmosis concentrated water recovery device.
The utility model to achieve the above object, adopts the following technical scheme that a kind of in purified water preparation process
First output end of reverse osmosis concentrated water recovery device, including high saliferous reverse osmosis unit, the high saliferous reverse osmosis unit passes through
First pipe enters concentrated water recovery system, and the second output terminal of the high saliferous reverse osmosis unit enters concentrated water by second pipe
Exhaust system；Wherein, first pressure gauge, conductivity analyzer, temperature sensor, first are disposed in the first pipe
Flow sensor and first flow regulating valve；Second pressure gauge, second flow sensor are disposed on the second pipe
With second flow regulating valve；
When conductivity analyzer detects that the conductivity of the concentrated water for flowing through first pipe is raised and lowered, conductivity analysis
The electric signal that instrument will test is sent to PLC controller, is increased or is subtracted by the aperture of PLC controller control second flow regulating valve
It is small, so that the conductivity for flowing through the concentrated water of second pipe is maintained between 70~150 μ s/cm；Wherein, PLC controller pair
The conductivity value that conductivity analyzer uploads carries out conductivity gradient fractionation, and makes the conductivity gradient fractionation and first flow
The preset flow gradients classification of sensor is matched, to control opening for first flow regulating valve by first flow sensor
Degree increases or reduces.
The utility model has the beneficial effects that the high degree of automation of the utility model, control precision is high, concentrated water recyclable device
Only have 40%~50% secondary concentrated water to be discharged after processing, has saved water resource, reduced cost, treated, and concentrated water can be again
It is secondary to enter counter-infiltration system, it not will increase counter-infiltration system operation burden, improve producing water ratio.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Shown in Fig. 1, it is related to a kind of reverse osmosis concentrated water recovery device in purified water preparation process, including high saliferous is anti-
First output end of permeability apparatus 1, the high saliferous reverse osmosis unit 1 enters concentrated water recovery system by first pipe, described
The second output terminal of high saliferous reverse osmosis unit 1 enters concentrated water discharge system by second pipe；Wherein, in the first pipe
First pressure gauge 2, conductivity analyzer 3, temperature sensor 4, first flow sensor 5 and first flow is disposed with to adjust
Valve 6；Second pressure gauge 7, second flow sensor 8 and second flow regulating valve 9 are disposed on the second pipe；
When conductivity analyzer 3 detects that the conductivity of the concentrated water for flowing through first pipe is raised and lowered, conductivity point
The electric signal that analyzer 3 will test is sent to PLC controller (not shown), by PLC controller control second flow regulating valve 8
Aperture increases or reduces, so that the conductivity for flowing through the concentrated water of second pipe remains between 70~150 μ s/cm；
Wherein, PLC controller carries out conductivity gradient fractionation (can be divided into 1,2,3 grade) to the conductivity value that conductivity analyzer 3 uploads,
And make the conductivity gradient fractionation and first flow sensor preset flow gradients classification (can equally be divided into 1,2,3 grade) into
Row matching, to be increased or reduced by the aperture that first flow sensor 5 controls first flow regulating valve 6.
Wherein, the present apparatus is also by the pressure gauge of setting, temperature sensor come detection device each section pressure and temperature value,
Adjust 6~9bar of reverse osmosis pressure that pressure meets RO operation.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
