Technical field
The utility model relates to a kind of EDI device, particularly relates to a kind of EDI device of water quality auto-control.
Background technology
EDI (Elcctrodeionization) is a kind of pure water manufacturing technology that ion exchange technique, ion-exchange membrane technique and ion-conductance migrating technology are combined.It combines electrodialysis and ion exchange technique, utilizes the two end electrodes high pressure to make that charged ion moves in the water, and cooperates ion exchange resin and selective resin film to move removal with speeding-up ion, thereby reaches the purpose of desalt.In the EDI desalting process, ion is eliminated by ion-exchange membrane under electric field action.Simultaneously, water molecules produces hydrogen ion and hydroxide ion under electric field action, and these ion pair ion exchange resin carry out cyclic regeneration, so that ion exchange resin keeps optimum regime.
Traditional EDI equipment adopts manually control, need when cleaning the EDI individual module complete assembly is out of service, shortcoming such as have operation inconvenience, can not move continuously.
Summary of the invention
At traditional E DI operation of equipment inconvenience, shortcoming such as can not move continuously, the purpose of this utility model is to provide a kind of level of automation height, modular characteristics is obvious, is easy to maintaining, effectively reduces the EDI water quality device for automatically regulating of human cost.
For achieving the above object, technical scheme provided by the invention is: a kind of EDI water quality device for automatically regulating, comprise the pure water case 1 that connects successively by pipeline, topping-up pump 2, EDI system 3, nitrogen-sealed water tank 4, it is characterized in that described EDI system 3 is made up of at least two EDI modules, and every cover EDI module all contains two pairs of inlet channels 8, and it is arranged side by side with pipe blow-through 6, water producing pipe road 7 is connected to nitrogen-sealed water tank 4, resistance meter 11 is installed on the water producing pipe road, dense waterpipe is connected to collects water tank 5, water producing pipe road 7 and dense waterpipe 9 all divide and pick out a pipeline and clean reflux line 10 and link to each other, and valve all is installed on each pipeline, and the employing PLC of system controls automatically;
Branch picks out a pure water reflux line 13 and is back to pure water case 1 on the described water producing pipe road 7, and motorized valve 711,712 is installed on water producing pipe road 7 and the reflux line 13;
In the described nitrogen-sealed water tank 4 liquidometer 12 is installed.
Description of drawings
Fig. 1 is the utility model Patent equipment one-piece construction figure;
Fig. 2 is the single EDI modular structure of the utility model patent figure.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
The pure water case, 2. topping-up pump, 3.EDI system, 4. nitrogen-sealed water tank, 5. collect water tank, 6. pipe blow-through, 7. the water producing pipe road, 8. inlet channel, 9. dense waterpipe, 10. clean reflux line, 11. resistance meters, 12. liquidometers, 13. pure water reflux lines.
Shown in accompanying drawing 1 the utility model one-piece construction figure, a kind of EDI water quality device for automatically regulating comprises the pure water case 1, topping-up pump 2, EDI system 3, the nitrogen-sealed water tank 4 that connect successively by pipeline.As shown in Figure 1, EDI system 3 is made up of at least two EDI modules, and every cover EDI module all contains two pairs of inlet channels 8, and it is arranged side by side with pipe blow-through 6, water producing pipe road 7 is connected to nitrogen-sealed water tank 4, and dense waterpipe is connected to collects water tank 5, and water producing pipe road 7 and dense waterpipe 9 all divide and pick out a pipeline and link to each other with cleaning reflux line 10, valve all is installed on each pipeline, and system adopts PLC to control automatically; Branch picks out a pure water reflux line 13 and is back to the pure water case on the water producing pipe road 7, on water producing pipe road 7 and the pure water reflux line 13 motorized valve is installed; Liquidometer 12 is installed in the nitrogen-sealed water tank 4.
Embodiment 1: when system normally moves, valve A2, A3 on the inlet channel 8, A6 on the water producing pipe road 7, valve A7 on the dense waterpipe 9 opens, valve A1, A4 on the pipe blow-through 6, the A8 on the A5 on the water producing pipe road, the dense waterpipe closes, after pure water in the pure water case 1 enters EDI system 3 and carries out desalination through topping-up pump 2, ultrapure water enters water producing pipe road 7, and dense water enters by dense waterpipe 9 and collects water tank 5.When nitrogen-sealed water tank 4 was in high-water or produces the water deteriorating water quality, motorized valve 711 was opened, and motorized valve 712 cuts out, EDI produces water and returns the pure water case and circulate, if when nitrogen-sealed water tank 4 is in low-water level or produce water water quality when qualified, motorized valve 712 is opened, motorized valve 711 cuts out, and produces water and advances nitrogen-sealed water tank.
When single EDI in the EDI system needs matting (for ease of explanation, with EDI module among Fig. 2 is example), earlier EDI module direct supply cuts out valve A2, A3 on the inlet channel 8, the A6 on the water producing pipe road 7, valve A7 on the dense waterpipe 9 closes, valve A1, A4 on the pipe blow-through 6, the A8 on the A5 on the water producing pipe road, the dense waterpipe opens, and rinse water is through 10 times cleaning water tanks of stream pipeline, carry out matting, after water quality is qualified, can come into operation.
When following situation occurring, the EDI module needs matting: 1) under the constant situation of temperature and flow, producing differential water pressures has increased by 50%; 2) under the constant situation of temperature and flow, dense differential water pressures has increased by 50%; 3) under the constant situation of inflow temperature, flow, specific conductivity, produce quality and descend; 4) under temperature-resistant situation, module resistance has increased by 25%.
In sum, the utility model characteristics are can realize single EDI module on-line cleaning under the non-stop-machine situation of whole EDI system; And when EDI produces the hydration lattice or nitrogen-sealed water tank when being in low liquid level, be delivered to nitrogen-sealed water tank; When EDI produces water when defective or nitrogen-sealed water tank when being in high liquid level, be back to the pure water case, guarantee effluent quality.This device EDI system is in 24 hours uninterrupted recurrent states, prolongs EDI resin work-ing life etc.; And this device good looking appearance, the level of automation height, modular characteristics is obvious, is easy to maintaining, effectively reduces human cost.
The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.
