Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
Embodiment 1
In the embodiment of the present invention, a kind of mixed bed device that can be automatically drawn into acid solution, lye, including mixed bed, lye tank 15, acid
Liquid case 16, sour inlet tube 17, alkali inlet tube 18 and siphon pipe 19, mixed bed by mixed bed cabinet 10, water inlet distributor 11, into alkali device
12, zwitterion layer switching layer 13, baffle 14 form, and the inside of mixed bed cabinet 10 is successively arranged water inlet distributor from top to bottom
11, into alkali device 12, zwitterion layer switching layer 13, baffle 14, water inlet distributor 11 passes through on the top of mixed bed cabinet 10
Pipeline is connect with air door 1, inlet valve 2 respectively；The other end of inlet valve 2 connects siphon pipe by siphon tube valve 3
19, siphon pipe 19 is separately connected sour inlet tube 17, alkali inlet tube 18, and another nozzle of sour inlet tube 17 is located in lye tank 15,
Another nozzle of alkali inlet tube 18 is located in acid solution case 16.It is additionally provided with pipeline into the top of alkali device 12, the pipeline is by into alkali
Valve 4 connects alkali inlet tube 18.Intermediate water discharging valve 9 is also provided on mixed bed cabinet 10, intermediate water discharging valve 9 is also located at yin-yang
On interface at sheath switching layer 13, the lower section of mixed bed cabinet 10 further respectively have backwashing water valve 5, acid inlet valve door 6,
Penstock 7, compressed air valve 8 are produced, acid inlet valve door 6 is also connect with sour inlet tube 17.
The use process of preferred embodiment: when normal work water flow first continuously by inlet valve 2 into
Enter mixed bed 10, obtain the water of high-purity after zwitterion layer switching layer 13, is flowed out from penstock 7 is produced.When zwitterion layer
When the work certain time failure of switching layer 13, resin regeneration need to be carried out, 13 function of zwitterion layer switching layer is restored.Backwash water from
Backwashing water valve 5 enters mixed bed cabinet 10 by mixed bed bottom, while compressed air enters from compressed air valve 8, by yin, yang from
The layering of subtree rouge, backwash water raffinate are discharged from intermediate water discharging valve 9, and compressed gas is discharged from air door 1.Zwitterion layer is handed over
The anions and canons resin changed on layer 13 needed after standing injection acid, lye regenerated, at this moment open siphon tube valve 3, water from
Siphon pipe 19 quickly flows down, and takes away the gas in sour inlet tube 17 and alkali inlet tube 18, and alkali, acid solution are from lye tank 15 and acid solution case
16 are inhaled into sour inlet tube 17 and alkali inlet tube 18, are entered in mixed bed cabinet 10 by alkali-feeding valve door 4, acid inlet valve door 6, lye
The liquid level of case 15 and acid solution case 16 declines therewith.When liquid level drops to sour inlet tube 17 and alkali 18 lower nozzle of inlet tube, gas
Body enters in sour inlet tube 17 and alkali inlet tube 18 from nozzle, destroys the negative pressure in sour inlet tube 17 and alkali inlet tube 18, acid,
Lye stops entering mixed bed cabinet 10, and anions and canons resin regeneration is completed.Siphon tube valve 3 is closed, inlet valve 2 is opened, opens
Beginning is just washed, mixes rouge, and the regeneration of zwitterion layer switching layer 13 is completed.Treated water can be re-started after the completion of regeneration
Ion exchange process has started next working cycles.Adjust sour inlet tube 17 and 18 lower nozzle height of alkali inlet tube, so that it may
Acid, alkali number needed for adjustment regeneration.So circulation realizes the exchange of zwitterion layer switching layer 13 and regeneration function.
Mixed bed ion-exchange method is exactly that anion-cation exchange resin is placed in the same exchanger, they are mixed
It closes, bed is answered by the staggered multi-stag of countless anion-cation exchange resins so can regard as, the yin, yang of contained salt in water
Ion then by resins exchange, and obtains the water of high-purity by the exchanger.
Due to anion-cation exchange resin be it is mutually uniform, so the exchange reaction of its anions and canons almost simultaneously into
Row.The cation exchange and anion exchange of water are repeatedly staggeredly to carry out in other words.Generated H and OH is exchanged all through H-type
It cannot accumulate, substantially eliminate the influence of counter ion, exchange the ratio of progress more thoroughly.
Using internal method of reproduction.It is different using the specific gravity of two kinds of resins when regeneration, make anion and cation exchange resin with backwash
Complete separation, resin cation are deposited on down, and resin anion (R.A.) floats on above, then resin cation with hydrochloric acid (or sulfuric acid) again
It is raw, resin anion (R.A.) burning regeneration.
Top is equipped with water inlet distributor 11, into alkali device 12, the outstanding waste discharge acid in centre, salkali waste liquid device, lower part have into acid and
Water dispensing apparatus.It is from top water distribution when operation, lower part produces water；Be when regeneration from top into alkali, lower part into acid, intermediate row spent acid,
Spent lye, the water inlet distributor 11 on 13 top of zwitterion layer switching layer, enables to be uniformly distributed into water.
Anion exchange resin regeneration lye is sent by sour inlet tube 17.Cation regenerant exchanger resin acid solution by
Bottom alkali inlet tube 18 enters, and regenerated acid, alkali wasteliquid are discharged by intermediate water discharging valve 9.Intermediate water discharging valve 9 is arranged in yin-yang
On the interface of sheath switching layer 13, acid, alkali wasteliquid and flushing liquor when for draining regeneration.
Mixed bed regenerative process after efficiency lost resin is two-step method regeneration, specifically: backwash, stand (layering), into alkali, set
Change, backwash, layering, into acid, displacement, just washing, mixed rouge, just washing, one-step method regeneration can also be used, i.e., simultaneously into acid, alkali.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
