EDI (Continuous Electro-Deionization) yog cov cuab yeej kho dej uas siv cov tshuab electrodialysis thiab ion exchange technologies. Nws lub ntsiab lus yog nyob rau hauv kev siv cov kev xaiv permeability ntawm ion pauv daim nyias nyias thiab lub siab tsiv teb tsaws kev ua tau zoo ntawm ion pauv resins kom ua tiav cov kev taw qhia tsiv teb tsaws ntawm ions nyob rau hauv dej nyob rau hauv qhov kev txiav txim ntawm ib tug DC hluav taws xob teb. Tib lub sijhawm, H⁺ thiab OH⁻ ions tsim los ntawm dej ionization nyob rau hauv hluav taws xob tsis tu ncua electro-regenerate ion exchange resin, yog li ua tiav synchronous deionization thiab resin regeneration yam tsis tas yuav tsum tau kaw thiab tshuaj regeneration nrog acids los yog alkalis.
1. Cov dej nkag mus rau hauv EDI system, nrog rau feem ntau ntws mus rau hauv cov resin/membrane sab hauv, thaum lwm feem ntws raws sab nrauv ntawm daim nyias nyias los ntxuav cov ions uas tau permeated los ntawm daim nyias nyias.
2. Cov resin khaws cov ions yaj hauv dej.
3. Nyob rau hauv qhov kev txiav txim ntawm cov electrodes, anions txav mus rau qhov zoo electrode, thiab cations tsiv mus rau qhov tsis zoo electrode.
4. Cations permeate los ntawm cation exchange membrane thiab tawm sab nraum lub resin/membrane.
5. Anions permeate los ntawm anion exchange membrane thiab tawm sab nraum lub resin/membrane.
6. Concentrated ions raug tso tawm los ntawm txoj kev dej khib nyiab.
7. Deionized dej ntws tawm ntawm cov resin/membrane.
