Embodiment
Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In the embodiment of the present invention, one can suck acid solution automatically, the novel mixed bed device of alkali lye, comprise mixed bed, lye tank 15, acid solution case 16, acid liquid-inlet pipe 17, alkali liquid-inlet pipe 18 and siphon pipe 19, mixed bed is by mixed bed casing 10, water inlet distributor 11, enter alkali device 12, zwitterion layer switching layer 13, baffle plate 14 forms, the inside of mixed bed casing 10 is provided with water inlet distributor 11 from top to bottom successively, enter alkali device 12, zwitterion layer switching layer 13, baffle plate 14, water inlet distributor 11 is on the top of mixed bed casing 10, and by pipeline respectively with air door 1, inlet valve 2 connects, the other end of inlet valve 2 connects siphon pipe 19 by siphon pipe valve 3, and siphon pipe 19 connects sour liquid-inlet pipe 17, alkali liquid-inlet pipe 18 respectively, and another mouth of pipe of sour liquid-inlet pipe 17 is arranged in lye tank 15, and another mouth of pipe of alkali liquid-inlet pipe 18 is arranged in acid solution case 16.The top entering alkali device 12 is also provided with pipeline, and this pipeline connects alkali liquid-inlet pipe 18 by alkali-feeding valve door 4.Mixed bed casing 10 also offers middle water discharging valve 9, middle water discharging valve 9 is also positioned on the separation surface at zwitterion layer switching layer 13 place, the below of mixed bed casing 10 is also respectively equipped with backwashing water valve 5, acid inlet valve door 6, produces penstock 7, compressed air valve 8, and acid inlet valve door 6 is also connected with sour liquid-inlet pipe 17.
The use procedure of preferred embodiment: during normal work, current first continuously enter mixed bed 10 by inlet valve 2, obtain highly purified water after zwitterion layer switching layer 13, flows out from product penstock 7.When zwitterion layer switching layer 13 works certain hour inefficacy, need resin regeneration be carried out, recover zwitterion layer switching layer 13 function.Backwash water is from backwashing water valve 5 by entering mixed bed casing 10 bottom mixed bed, and pressurized air enters from compressed air valve 8 simultaneously, and by the layering of anions and canons resin, backwash water raffinate is discharged from middle water discharging valve 9, and pressurized gas is discharged from air door 1.Anions and canons resin in zwitterion layer switching layer 13 needs to inject acid after leaving standstill, alkali lye regenerates, at this moment siphon pipe valve 3 is opened, water flows down fast from siphon pipe 19, take away the gas in sour liquid-inlet pipe 17 and alkali liquid-inlet pipe 18, alkali, acid solution are inhaled into sour liquid-inlet pipe 17 and alkali liquid-inlet pipe 18 from lye tank 15 and acid solution case 16, enter in mixed bed casing 10 by alkali-feeding valve door 4, acid inlet valve door 6, the liquid level of lye tank 15 and acid solution case 16 declines thereupon.When liquid level drops to sour liquid-inlet pipe 17 and alkali liquid-inlet pipe 18 lower nozzle, gas enters sour liquid-inlet pipe 17 and alkali liquid-inlet pipe 18 from the mouth of pipe, destroy the negative pressure in sour liquid-inlet pipe 17 and alkali liquid-inlet pipe 18, acid, alkali lye stop entering mixed bed casing 10, and anions and canons resin regeneration completes.Close siphon pipe valve 3, open inlet valve 2, start just to wash, mix fat, complete the regeneration of zwitterion layer switching layer 13.Just can re-start the ion exchange process of processed water after having regenerated, start next working cycle.Adjust sour liquid-inlet pipe 17 and alkali liquid-inlet pipe 18 lower nozzle height, with regard to the acid needed for adjustable regeneration, alkali number.Circulation like this achieves zwitterion layer switching layer 13 and exchanges and refresh function.
Mixed bed ion exchange method is placed on anion-cation exchange resin in same interchanger exactly, they are mixed, so can regard as by the multiple bed of the staggered multi-stage type of countless anion-cation exchange resin, in water, the anions and canons of contained salt is by this interchanger, then by resins exchange, and obtain highly purified water.
Because anion-cation exchange resin is mutually uniform, so the permutoid reaction of its anions and canons is almost carried out simultaneously.The cationic exchange of water and anionresin in other words repeatedly interlocks and carries out.H and OH produced through H type clearing house can not accumulate, and substantially eliminates the impact of gegenion, and it is more thorough that exchange is carried out.
Adopt internal regeneration method.Utilize the proportion of two kinds of resins different during regeneration, make the complete separation of anion and cation exchange resin with backwash, resin cation (R.C.) is deposited on down, above resin anion(R.A) floats over, then resin cation (R.C.) hydrochloric acid (or sulfuric acid) regeneration, resin anion(R.A) is with burning regeneration.
Top is provided with water inlet distributor 11, enters alkali device 12, and middle outstanding waste discharge acid, waste lye device, bottom has into acid and water dispensing apparatus.Be from top water distribution during operation, water is produced in bottom; Be enter alkali from top during regeneration, acid is entered in bottom, and middle waste discharge acid, waste lye, the water inlet distributor 11 on zwitterion layer switching layer 13 top, makes be uniformly distributed into water.
Namely anionite-exchange resin regeneration alkali lye sent into by sour liquid-inlet pipe 17.Cation regenerant exchange resin acid solution is entered by bottom alkali liquid-inlet pipe 18, and regenerating acid, alkali wasteliquid are discharged by middle water discharging valve 9.Middle water discharging valve 9 is arranged on the separation surface of zwitterion layer switching layer 13, acid during for draining regeneration, alkali wasteliquid and washing fluid.
Mixed bed regenerative process after efficiency lost resin is two-step approach regeneration, be specially: back flushing, leave standstill (layering), enter alkali, displacement, backwash, layering, enter acid, displacement, just wash, mixed fat, just the step such as to wash, also single stage method can be adopted to regenerate, namely enter acid, alkali simultaneously.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
In addition, be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
