1. Incazelo yenqubo Amanzi aluhlaza angamanzi omthombo, anokuqukethwe okuphezulu okuqinile okulenga kanye nobulukhuni obuphezulu.Ukuze kwenziwe amanzi angenayo ahlangabezane nezidingo zokungena kwe-osmosis ehlehlayo, isihlungi somshini sifakwa esinesihlabathi se-quartz esicolekile ngaphakathi ukuze kukhishwe okuqinile okumisiwe kanye nenhlabathi emanzini.Nokunye ukungcola.Ukwengeza uhlelo lwe-scale inhibitor lungangeza i-scale inhibitor nganoma yisiphi isikhathi ukunciphisa ukuthambekela kokuqina kwe-ion scaling emanzini futhi kuvimbele ukwakheka kwamanzi agxilile.Isihlungi esinembayo sifakwe isici sokuhlunga ikhekheba lezinyosi esinemba ngama-microns angu-5 ukuze siqhubeke sikhipha izinhlayiya eziqinile emanzini futhi sivimbele ubuso bolwelwesi ukuba lungaklwebheki.Idivaysi ye-osmosis engemuva iyingxenye eyinhloko yokukhipha usawoti emanzini.I-osmosis ehlanekezelayo enesigaba esisodwa ingasusa u-98% wama-ion kasawoti emanzini, futhi ukungcola kwe-osmosis ehlehlayo yesigaba sesibili kuhlangabezana nezidingo zabasebenzisi.
2. Ukusebenza kokuhlunga ngomshini
- I-Exhaust: Vula i-valve yokukhipha ephezulu kanye ne-valve yokungena ephezulu ukuze uthumele amanzi esisefweni ku-valve yokukhipha ephezulu ukuze uthole ukungena kwamanzi okuqhubekayo.
- Ukugeza kahle: Vula i-valve yokukhipha amanzi engezansi kanye ne-valve yokufaka ephezulu ukuze wenze amanzi adlule kungqimba lokuhlunga ukusuka phezulu ukuya phansi.Izinga lokugeleza kokungena ngu-10t/h.Kuthatha cishe imizuzu eyi-10-20 kuze kube yilapho amanzi ehlanzekile futhi esobala.
- Ukusebenza: Vula i-valve yokukhipha amanzi ukuze uthumele amanzi ezintweni ezisebenza ezansi nomfula.
- Ukuwashwa ngemuva: Ngemva kokuba imishini isisebenze isikhathi eside, ngenxa yokungcola okuvalelekile, amakhekhe okuhlunga akhiwa phezulu.Uma umehluko wengcindezi phakathi kokungena nokuphuma kwesihlungi umkhulu kuno-0.05-0.08MPa, ukuwashwa ngemuva kufanele kwenziwe ukuze kuqinisekiswe ukugeleza kwamanzi okushelelayo.Vula i-valve yokudonsa engaphezulu, i-backwash valve, i-valve yokudlula, shayela ngokugeleza kwe-10t / h, cishe imizuzu engu-20-30, kuze kube yilapho amanzi ecacile.Qaphela: Ngemva kokuwashwa ngemuva, okokusebenza okuwasha phambili kufanele kwenziwe ngaphambi kokuthi kuqale ukusebenza.
3. Ukuhlanza ukushintsha izinto ezithambile Umgomo wokusebenza kwesithambile ukushintshanisa i-ion.Isici se-ion exchanger ukuthi i-resin kufanele ivuselelwe njalo.Naka lezi zinkinga ezilandelayo uma usebenzisa:
- Uma ubulukhuni bekhwalithi yamanzi angcolile budlula izinga (imfuneko yokuqina ≤0.03mmol/L), kufanele kumiswe futhi kuvuselelwe;2. Indlela yokuvuselelwa kwe-resin ye-cationic ukucwilisa i-resin emanzini anosawoti cishe amahora amabili, uvumele amanzi anosawoti ome, bese uwasebenzisa.Amanzi ahlanzekile ayahlehla, ungaqhubeka nokuwasebenzisa;
4. Ukwengeza uhlelo lwe-antiscant Iphampu yokulinganisa kanye nephampu yomfutho ophezulu iqala futhi ime ngesikhathi esisodwa, futhi inyakaze ngokuvumelanisa.I-scale inhibitor yi-MDC150 ekhiqizwa e-United States.Umthamo we-scale inhibitor: Ngokobunzima bamanzi aluhlaza, ngemva kokubala, umthamo we-antiscaant ungama-3-4 amagremu ngethani lamanzi aluhlaza.Ukungena kwamanzi kwesistimu kungu-10t / h, kanti umthamo ngehora ungama-30-40 amagremu.Ukucushwa kwe-scale inhibitor: engeza amalitha angama-90 amanzi ethangini lamakhemikhali, bese wengeza kancane kancane u-10 kg we-scale inhibitor, uhlanganise kahle.Lungisa ububanzi bephampu yemitha kusikali esihambelanayo.Qaphela: Isilinganiso esincane se-scale inhibitor akufanele sibe ngaphansi kuka-10%.
5. isihlungi esinembayo Isihlungi esinembayo sinokunemba kokuhlunga okungu-5μm.Ukuze kugcinwe ukunemba kokuhlunga, isistimu ayinawo ipayipi lokuwasha ngemuva.Isici sokuhlunga kusihlungi esinembayo ngokuvamile sihlala izinyanga ezingu-2-3, futhi singanwetshwa sibe izinyanga ezingu-5-6 ngokuya ngevolumu yangempela yokwelashwa kwamanzi.Ngezinye izikhathi ukuze kugcinwe ukugeleza kwamanzi, isici sokuhlunga singashintshwa kusengaphambili.
6. Ukuhlanzwa kwe-osmosis ehlehlayo Izakhi zolwelwesi lwe-osmosis ezihlehlayo zijwayele ukukala ngenxa yokunqwabelana kokungcola emanzini isikhathi eside, okuholela ekwehleni kokukhiqizwa kwamanzi kanye nokuncipha kwezinga lokukhipha usawoti emanzini.Ngalesi sikhathi, i-membrane element idinga ukuhlanzwa ngamakhemikhali.
Uma okokusebenza kunomunye wale mibandela elandelayo, kufanele kuhlanzwe:
- Izinga lokugeleza kwamanzi omkhiqizo liwela ku-10-15% yenani elivamile ngaphansi kwengcindezi evamile;
- Ukuze kugcinwe izinga elijwayelekile lokugeleza kwamanzi omkhiqizo, ukucindezela kwamanzi okuphakelayo ngemva kokulungiswa kwezinga lokushisa kuye kwanda ngo-10-15%;3. Izinga lamanzi lomkhiqizo lehliswe ngo-10-15%;ukungena kukasawoti kukhuphuke ngo-10-15%;4. Ingcindezi yokusebenza inyuswe ngo-10- 15%.15%;5. Umehluko wengcindezi phakathi kwezigaba ze-RO ukhule kakhulu.
7. Indlela yokugcina ye-membrane element:
Isitoreji sesikhathi esifushane sifanele amasistimu e-osmosis ahlehlayo avaliwe izinsuku ezingu-5-30.
Ngalesi sikhathi, isici se-membrane sisafakwe emkhunjini wokucindezela wesistimu.
- Sula isistimu ye-osmosis engemuva ngamanzi okuphakelayo, futhi unake ukususa ngokuphelele igesi ohlelweni;
- Ngemva kokuba umkhumbi wokucindezela kanye namapayipi ahlobene nawo agcwaliswe ngamanzi, vala amavalvu afanele ukuvimbela igesi ukuthi ingangeni ohlelweni;
- Njalo ezinsukwini ezi-5 Geza kanye njengoba kuchazwe ngenhla.
Ukuvikelwa kokuvala ukusebenza kwesikhathi eside
- Ukuhlanza izakhi ze-membrane ohlelweni;
- Lungiselela uketshezi olubulala amagciwane ngamanzi akhiqizwe yi-osmosis ehlehlayo, futhi usule isistimu ye-osmosis ehlehlayo ngoketshezi olubulala amagciwane;
- Ngemva kokugcwalisa i- reverse osmosis system ngoketshezi olubulala amagciwane, vala amavalvu afanele Gcina uketshezi olubulala amagciwane ohlelweni.Ngalesi sikhathi, qiniseka ukuthi uhlelo lugcwaliswe ngokuphelele;
- Uma izinga lokushisa lesistimu lingaphansi kwama-degree angu-27, kufanele lisetshenziswe ngoketshezi olusha olubulalayo njalo ezinsukwini ezingu-30;uma izinga lokushisa lingaphezu kuka-27 degrees, kufanele lisetshenziswe njalo ezinsukwini ezingu-30.Shintsha isixazululo sokuvala inzalo njalo ezinsukwini eziyi-15;
- Ngaphambi kokuthi uhlelo lwe-osmosis oluphambene luphinde lusetshenziswe, sula uhlelo ngamanzi okuphakelayo anengcindezi ephansi ihora elilodwa, bese uhlanza uhlelo ngamanzi okuphakelayo anengcindezi ephezulu imizuzu emi-5-10;kungakhathaliseki ukucindezela okuphansi noma ukucindezela okuphezulu, amanzi omkhiqizo wesistimu Wonke ama-valve okukhipha amanzi kufanele avuleke ngokugcwele.Ngaphambi kokuthi uhlelo luqale futhi ukusebenza okujwayelekile, hlola futhi uqinisekise ukuthi amanzi omkhiqizo awanawo ama-fungicides
