A kind of mixed ion exchanger
Technical field
The utility model relates to a kind of water treating equipment, is specifically related to a kind of mixed ion exchanger.
Background technology
At present, ion-exchanger has broad variety, main adopt have fixed-bed ion exchanger, thermopnore ion-exchanger and a float bed type ion-exchanger, wherein, float bed type ion-exchanger has many advantages, but in backwash, because its expansion space is little, big reverse washing need to arrange special rinser, and cost is high, complicated operation; Fixed-bed ion exchanger is also due to complicated operation, and resin is " disorderly layer " and have the shortcoming that regeneration effect is poor, soda acid waste is more serious easily; Thermopnore ion-exchanger requires that raw water quality is stable, softening water is exerted oneself changes little, the condition such as uninterrupted operation continuously.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of mixed ion exchanger, and the pipeline circulating system that this interchanger adopts is regenerated under without top pressure condition, has improved regeneration effect, has saved soda acid consumption.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of mixed ion exchanger, comprise cylindrical shell, in this cylindrical shell outside, be provided with pipeline circulating system and gas exhaust duct, described pipeline circulating system is mainly by input duct, inlet channel, acid inlet tube, alkali inlet tube road, enters compressed air line, backwash drainage pipeline, cleans outlet conduit and just washing drainage pipeline to form; Described inlet channel, acid inlet tube, alkali inlet tube road, enter compressed air line, backwash drainage pipeline, clean outlet conduit and just washing drainage pipeline and be all communicated with input duct; Described inlet channel, acid inlet tube, alkali inlet tube road, enter compressed air line, backwash drainage pipeline, clean outlet conduit and just washing and on drainage pipeline, be equipped with valve.
Described pipeline circulating system also comprises top drainage pipeline and the regenerated liquid discharge line being connected with input duct.
On described top drainage pipeline and regenerated liquid discharge line, be equipped with valve.
The beneficial effects of the utility model are: ion-exchanger described in the utility model, in the pipeline circulating system adopting, set up the pipeline of difference in functionality, and make one-piece construction arrangement reasonable, treatment effect is better; The alkali inlet tube road and the acid inlet tube that adopt, not only improved processing efficiency and regeneration effect, saved soda acid consumption, and make each operation of components convenient, alleviated the workload of routine maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
A kind of mixed ion exchanger, as shown in Figure 1, comprise cylindrical shell 1, in this cylindrical shell outside, be provided with pipeline circulating system 2 and gas exhaust duct 3, this pipeline circulating system 2 is connected to the bottom of cylindrical shell 1 from the top of cylindrical shell 1, this recycle system 1 by input duct 20, inlet channel 21, acid inlet tube 22, alkali inlet tube road 23, enter compressed air line 24, backwash drainage pipeline 25, clean outlet conduit 26, just wash drainage pipeline 27, top drainage pipeline 28 and regenerated liquid discharge line 29 and form; This inlet channel 21, acid inlet tube 22, alkali inlet tube road 23, enter compressed air line 24, backwash drainage pipeline 25, clean outlet conduit 26, just wash drainage pipeline 27, top drainage pipeline 28 and regenerated liquid discharge line 29 and be all connected with input duct 20; In inlet channel 21, acid inlet tube 22, alkali inlet tube road 23, enter compressed air line 24, backwash drainage pipeline 25, clean outlet conduit 26, just wash on drainage pipeline 27, top drainage pipeline 28 and regenerated liquid discharge line 29 and be equipped with valve.
Wherein, inlet channel 21 is two, is connected respectively with input duct 20, on these two inlet channels, is respectively equipped with valve A and C.During use, open the water intaking valve A on inlet channel 21 and clean the cleaning outlet valve B on outlet conduit 26, former water enters cylindrical shell 1 inside by input duct 20, exchanged when in former water, contained salt yin, yang ion is through anion and cation exchange resin, remove, the clear water after processing is discharged by cleaning outlet valve.When zwitterion resin in cylindrical shell 1 is saturated, need to carry out resin regeneration, now close water intaking valve A and clean outlet valve B, open into the alkali-feeding valve G on alkali lye pipeline 23 or enter acid inlet valve F and the compressed air valve E on acid line 22, pass into alkali lye or acid solution, the pH value detecting respectively in water by top water discharge valve H, regenerated liquid outlet valve I is determined regeneration situation, and by backwash water discharge valve D, waste water is discharged in tank.When needs clean cylindrical shell 1, open former water water intaking valve C and just washing water discharge valve J, close other valves, cylindrical shell 1 is carried out to clean-drain.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
