Description
Technical field
The present invention relates to ion exchange resin on-line cleaning technical field, specifically a kind of simple in structure, recovery when
Between the online recovery device of resin cation iron poisoning short, that resuscitation effect is thorough, the wasting of resources is low.
Background technology
It is well known that cation exchange resin is in station boiler demineralized water, Industrial Boiler softened water and pure water production etc.
Go in water removal to widely use in the water treatment facilities of calcium ions and magnesium ions.The device often touches iron content underground in use
Water or caused by the pipeline rust into iron ion is carried in water, cause cation exchange resin to be polluted be subject to iron ion, commonly referred to as
For iron poisoning.Although iron ion content is seldom in water, year in year out operation go down, iron ion it is more long-pending in cation exchange groups more
It is more, most of operating capacity of resin is occupied, causes resin to Ca2+、Mg2+The decline of ion-exchange capacity, water outlet water
Matter is exceeded, and the cycle of operation shortens, and water yield is reduced, a series of problems, such as regenerating agent consumption increase, can be caused when serious device without
Method operation is gone down.
It is difficult by the Fe on resins exchange group with the salt regenerated liquid of conventional low concentration after resin iron poisoning3+Under displacement
Come.People employ different resin iron poisoning method for resuscitation.The visual iron poisoning degree of conventional iron poisoning method for resuscitation it is different and
It is different.Slight iron poisoning can recover in tank.When iron poisoning is deeper, recover using outside tank.
Method in tank：It is inverse with 6 m/h flow velocitys with the 8.0%HCl solution of 3 times of resin volumes thoroughly after backwash resin bed
To flowing through resin bed.The layer is rinsed to water outlet pH >=5.5 with raw water.With the 9.0%NaCl solution of 3 times of resin volumes, with 6 m/
H flow velocitys flow countercurrently through resin bed.5 min of resin bed is rinsed with 9 m/h flow velocitys complete resin transfer moulding with softened water.It is transferred to normal
Soften exchange process.This method is suitable for the recovery of slight iron poisoning resin, but effect is not ideal enough.
The outer method of tank：When resin iron poisoning is extremely serious, some units are more preferable in the hope of obtaining even using the outer recovery method of tank
Resuscitation effect.Thoroughly resin is moved into dedicated cleaner after backwash resin bed.With 3 times of resin volumes
8.0%HCl solution, soaks resin at twice, is slowly stirred 40 min, interval 2 h emptyings waste liquid is once.With 5 times of resin volumes
Raw water embathe resin points for 3 times, be slowly stirred, 5 min emptyings waste water is once.With the 9.0%NaCl solution of 3 times of resin volumes,
Resin is soaked by preceding method and is cleaned.Again with 3 times of resin volume 8.0%NaOH solution, resin and clear is soaked by preceding method
Wash.Finally using the 9.0%NaCl solution of 3 times of resin volumes, after soaking resin by preceding method, resin is returned loaded on exchange
In tank, and 5 min of resin is cleaned with 9 m/h flow velocitys with softened water.Complete the outer recovery overall process of tank, be transferred to normally soften it is exchanged
Journey.

Effect, its online recovery step are as follows：（1）Analysis detection iron poisoning degree：10 mL colors are taken to change, be tentatively judged as
The resin of iron poisoning is placed in 100 mL beakers, adds the HCl solution of 30 mL 8.0%, mixes slowly 15 min, stands 0.5
H, takes supernatant to measure total iron content, judges resin iron poisoning degree with this；（2）Determine reduction recovery method technological parameter：A. also
Former agent dosage：The dosage of sodium sulfite should be determined with the number of iron content in measured resin, be calculated by reaction equation
Theoretical amount, considers that it is that reducing agent uses total amount, reducing agent solution concentration to be multiplied by 1.2 times of regeneration specific consumption after reducing agent purity
It is advisable with 5.0%~6.0%, to prevent the generation of bulky ferric hydroxide precipitate, when preparing reducing solution with hydrochloric acid by reducing solution pH value
5.5~6.5 are adjusted to be allocated；（3）On-line cleaning is carried out：The above-mentioned liquid calculated is added in molten medicine-chest, is then opened
Into medicine valve and liquid valve, blowdown valve, backwash liquid valve, backwash valve and outlet valve are closed, then opens circulating pump, cleaning solution passes through
Cleaning solution in molten medicine-chest is entered ion exchange by the effect of circulating pump along cleaning inlet tube by the outlet pipe of ion-exchanger
Then device is discharged into cleaning outlet tube by water inlet pipe and eventually enters into molten medicine-chest progress wash cycles, waste water is arranged through blow-off pipe
Go out；（4）Resin regeneration：Use Na2SO3After reduction, substantial amounts of Fe is generated2+, when a large amount of functional groups and Fe on resin2+From
After son combines, the softening power of resin declines, it is therefore desirable to the resin regeneration of routine is carried out with NaCl solution, 9% NaCl is molten
Liquid is added in molten medicine-chest, then uses the flow velocity for flowing countercurrently through resin bed to be advisable with 10 m/h, using reverse circulation technique, reduction
The time of contact of liquid and resin should reach 2.0 more than h, and the sodium ions content in solution is high, and functional group can discharge Fe2+From
Son and combined with sodium ion, such resin has just recovered exchange capacity, carries out the regeneration of resin；（5）Backwash：Cleaning solution is clear
Need to be rinsed with water after the completion of washing, at this moment close into medicine valve, liquid valve, outlet valve and open backwash valve and backwash liquid valve, so
After open backwashing pump, the soft water in softened water tank entered in ion-exchanger along backwash tube by the effect of backwashing pump carry out it is clear
Wash, the final cleaning of ion-exchanger, the liquid cleaned on inlet tube are finally realized by the backwash outlet tube discharge of top
Body flow velocity is 8 ~ 12 m/h, ensures that cleaning is thorough.
Backwash in the present invention is first with the softened water back flush of 3 times of cation exchange resin volumes, with 3 times
The softened water of cation exchange resin volume is positive to be rinsed, and subsequent cation exchange resin can put into production use, and make flushing thorough
Bottom.
Mechanism is implemented in the cleaning of the present invention：Na2SO3In SO32-Fe3+It is reduced into Fe2+, so as to reduce resin to Fe3+
Combination, part Fe2+It can also further be reduced agent Na2SO3In sodium ion displacement, and react generation H+It can promote again
Fe2O3Dissolving, ferric hydroxide precipitate will not be produced in resuscitation process.
Reaction equation is: 2Fe3++ Na2SO3+ H2O = 2Fe2++ Na2SO4+ 2H+
The regeneration of routine is finally carried out with NaCl solution, you can iron poisoning resin is recovered, after softened water cleaning,
It is transferred to normal softening exchange process.
Since ion exchange resin is a kind of polymer, with corresponding functional group, under normal circumstances, conventional sodium from
Sub-exchange resin carries substantial amounts of sodium ion, and when the calcium ions and magnesium ions content in water is high, ion exchange resin can discharge sodium
Ion, functional group are combined with calcium ions and magnesium ions, and the calcium ions and magnesium ions content in such water reduces, and the hardness of water declines.Hard water just becomes
For soft water, this is the course of work of softened water equipment, same reason, the iron poisoning cation tree in present apparatus ion-exchanger
Fat, uses Na2SO3After reduction, substantial amounts of Fe is generated2+, when a large amount of functional groups and Fe on resin2+After ions binding, resin
Softening power decline, resin can be flowed through with sodium chloride solution, sodium ions content in solution is high at this time, and functional group can be released
Release Fe2+Ion and combined with sodium ion, such resin has just recovered exchange capacity, realizes the regeneration of resin, the present invention due to
Using the above structure and cleaning method, there is simple in structure, the recovery time is short, resuscitation effect is thorough, the wasting of resources is low etc..
