Description
Technical field
The present invention relates to a kind of cation exchange system, more particularly to a kind of multi-channel intelligent type cation exchange system.
Background technology
Hydrogen conductivity is the important indicator for characterizing Water of Power Plant (vapour) purity and erosion, refers to tested water (vapour) sample cationic
It is removed and (is converted to H+) after its electrical conductivity is monitored gained conductivity value.PH ammonia and amine are adjusted during this all
It is removed, remaining salt impurity is converted into the form of acid, erosion anion (Cl-Deng) detection sensitivity be greatly improved.
But carbon dioxide in actual applications in air is very easy to enter measuring system influence measurement, so a lot
In the case of require measurement water degassing (CO2) hydrogen conductivity, more accurately to reflect erosion anion-content in water.At present
Power plant's method for using of measurement degassing hydrogen conductivity be all by water by ion exchange resin column after, recycle boiling process degassing
(CO2) electrical conductivity is measured afterwards.
The defect of prior art：Using ion exchange column, resin, the numerical value meeting that hydrogen conductivity table is shown are not changed in time such as
Deviate actual value；Regenerated after resin replacement not exclusively or rinse insufficient, positive error can be caused by discharging the foreign ion of trace；
Some cationic ion-exchange resins discharge low polymer impurity, make the increase of background conductance rate, reduce detection sensitivity, cause
Hydrogen conductivity measurement is inaccurate；Power plant, which does not know when resin fails, causes measurement result to produce deviation；Need frequent regeneration tree
Fat, staff's working strength is big；One exchange column can only take up space big to an electrical conductivity table.
The content of the invention
Regenerate resin therein using electric regeneration method it is an object of the invention to provide one kind, without offline with soda acid again
Green resin, is the multi-channel intelligent type cation exchange system for the on-line measurement that real meaning realizes hydrogen conductivity.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：Including several parallel connections are with water inlet and fill
There is the electrically regenerative unit of storng-acid cation exchange resin, and lead in the operating current that each electrically regenerative unit is applied with 5-1000mA
Cross electrolysis water and produce H+, the water outlet of each electrically regenerative unit is connected with respective electric conductivity detector respectively, after electric conductivity detector
Containing H+Water sample return to each electrically regenerative unit the storng-acid cation exchange resin in electrically regenerative unit regenerated.
The present invention utilizes the continuous automatic regeneration cationic ion-exchange resin of electrochemical method, for measuring hydrogen electricity in the steam of power station
Conductance.Designing several passages can make thoroughly to be converted to H into the cation in water while handle some different water samples+, without
Any chemical reagent, available for hydrogen conductivity in on-line determination steam, energy-conserving and environment-protective, performance is stable, easy to operate.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the present invention includes four electricity with water inlet 1 and equipped with storng-acid cation exchange resin in parallel
Regeneration unit 2, and be applied with 5-1000mA operating current by electrolysis water in each electrically regenerative unit 2 and produce H+, it is each electrically regenerative
The water outlet of unit 2 is connected with respective electric conductivity detector 3 respectively, contains H after electric conductivity detector 3+Water sample return it is each electricity again
Raw unit 2 regenerates to the storng-acid cation exchange resin in electrically regenerative unit 2.
Existing single intelligent ion-exchange unit：Cationic ion-exchange resin is loaded in electrically regenerative device, water sample enters electricity
Regenerant ions switch removes cation therein.
NH in Power Plant Water Vapor4 +Content highest, the present invention is with NH4 +The electrically regenerative device of experiment investigation is carried out to remove cation
Except rate, specific test data is shown in Table 1.
Clearance of the present invention of table 1 to cation
The present invention can effectively remove the cation in steam, while a small amount of ion exchange resin therein is in exchange process
It is middle without dissolution, make the result of measurement more accurately and reliably.It relatively sees with conventional hydrogen conductance post water outlet anion measurement result
Table 2.
The comparison of the electrically regenerative device of table 2 and common cationic exchange column water outlet impurity content
As can be seen from Table 2, the common cationic exchange column that power plant's survey hydrogen conductivity is used is pure due to having loaded a large amount of resins
Water, which passes through, contains a small amount of formate, acetate and sulfate radical in exchange column water outlet, cause measurement result to have with actual measured value
Certain deviation；Minimal amount of storng-acid cation exchange resin is filled with the present invention, its water outlet and water inlet anion-content
It is identical, leachable is not measured in water outlet.Show that electrically regenerative ion exchange system can effectively go to remove water cationic, while in water outlet
Will not be with people's leachable.
The present invention is in parallel using multiple electrically regenerative units, and multiple water samples can be handled simultaneously, H is produced by electrolysis water+Regeneration
Storng-acid cation exchange resin in each unit, without changing resin, makes the measurement of hydrogen conductivity more accurate and real meaning
Justice realizes on-line measurement.
This method is compared with routinely degassing hydrogen conductivity detection method, with following technical characterstic：
(1) the micro storng-acid cation exchange resin of filling in electrically regenerative unit, it is ensured that effectively go to remove water cationic
And without any leachable.
(2) electrically regenerative unit persistently provides regeneration of current resin using low power loss constant source (5-1000mA), can make for a long time
Resin keeps Hydrogen, and any acid-base waste fluid is not produced.
(3) without worrying the Problem of Failure of resin, without considering that resin regeneration is incomplete or rinsing sordid problem.
(4) whole design of measuring system is multichannel, multiple water samples can be handled simultaneously, volume letter is small, it is easy to installs, is suitable to
Onsite application, can accurately reflect erosion anion-content size in water.
