Ukumboza Amathangi Okugcina I-Sludge: I-GFS, I-Epoxy Nensimbi Engagqwali Kuqhathaniswa
Udaka umsebenzi onzima kakhulu esitsheni sokuhlanzwa kwamanzi: lugqinsi, luyagqutheka, lunama-sulfide futhi luyaphila ngokwebhayoloji. Uhlelo lokufaka upende esitsheni sokugcina udaka lunquma ukuthi impahla ihlala iminyaka engu-30 noma yehluleka emgodini wokuqala obangelwa yi-H2S.
Upende lwethangi lokugcina udaka kumele lumelane ne-H2S, ama-asidi e-organic, ukugqutheka kanye nokushintshashintsha kwe-pH ezindaweni ezingamanzi nezingamagesi. I-Glass-fused-to-steel (GFS) enamel — ehlanganiswa ku-820–930°C futhi ihlolwe nge-holiday ku-1500V DC — iyindinganiso, idlula izinhlelo ze-epoxy ezidinga ukufakwa kabusha njalo ngeminyaka engu-8–12.
Yini Ehlasela Ithangi Lokugcina Udaka?
I-Hydrogen sulfide: ikhiqizwa yibhayoloji ye-anaerobic, i-H2S yakha i-sulfuric acid endaweni yegesi futhi igqwala insimbi nopende oluningi.
Izinto eziqinile ezigquthekayo: udaka lunamaphesenti angu-2–8 ezinto eziqinile ezinamatshe agqutheka upende othambile; i-vitreous enamel ku-6.0 Mohs ayinaki ukugqutheka.
Ukushintshashintsha kwe-pH: udaka olugayiwe nezinto zokwelapha ngamakhemikhali ziphusha i-pH ezindaweni ezibanzi, zidinga ukumelana ne-pH 1–14.
I-asidi ye-biogenic: ama-asidi aphilayo avela ekuboleni ahlasela izinto zokugqoka emgqeni wendle — indawo evamile yokwehluleka kokugqoka okufakwa endaweni.
Ziqhathanisa Kanjani Izinhlelo Eziyinhloko Zokugqoka?
I-GFS enamel: ingilazi ehlanganiswe ngamakhemikhali ezinhlangothini zombili, engenazimbobo kuze kufike ekuhlolweni kwe-1500V DC, i-pH 1–14, impilo yeminyaka engu-30+, ukunakekelwa okuncane.
I-epoxy esetshenziswa endaweni: iyonga ekuqaleni kodwa izwela ekulungiseni indawo nomswakama; imijikelezo ejwayelekile yokuphinda ucwebezelise ingu-8–12 iminyaka nokuma kwethangi.
Insimbi engagqwali: ukumelana okususelwa kuma-alloy ngaphandle kokumbozwa, ukuqina okuhle kakhulu kodwa izindleko eziphezulu zempahla, ikakhulukazi emathangini amancane abalulekile.
I-Polyurea / HDPE liners: izinketho eziguquguqukayo zokufaka i-liner, kodwa ukuqina kwemithungo, imikhawulo ye-UV kanye nokuguguleka kukhawulela umsebenzi wesikhathi eside wodaka.
Yikuphi Ukumbozwa Okufanele Ukucacisele Ukugcinwa Kodaka?
Empilweni ende yempahla: I-GFS enamel iwukuphela kwenketho efakwe efektri, ehlolwe ngephaneli ngayinye, efakazelwe eminyakeni eminingi yokusebenza kwe-sludge.
Ngekhwalithi ebhaliwe: funa amarekhodi okuhlolwa kwe-holiday ye-1500V, imibiko yobukhulu bokumboza kanye nokuthobela i-ISO 28765.
Ngokucaca kwezindleko: qhathanisa izindleko zomjikelezo wempilo — impilo yeminyaka engu-30 ye-GFS ivamise ukushaya imijikelezo eminingi yokuphinda kumboze i-epoxy ngezindleko zokunikwa impahla.
Ngama-mixer namakhava: cacisa ama-shaft ama-mixer ahambisana nokumboza namakhava angangeni umoya (aqondile noma ama-membrane) avikela indawo yegesi.
I-Matrix Yokuqhathanisa: Izinhlelo Zokumboza Amathangi Okugcina I-Sludge
Ipharamitha Yokuhlola | I-GFS Enamel | I-Epoxy Yendawo | Insimbi Engagqwali | I-HDPE Liner |
Ukumelana ne-H2S / i-asidi | Kuhle kakhulu — i-pH 1–14 | Kulingene — kufanele kugqokwe kabusha | Kuhle kakhulu | Kuhle |
Ukumelana nokugqokwa | I-Mohs engu-6.0 | Kuthambile — ingozi yokuguguleka | Kuhle kakhulu | Kulingene |
Ukuqinisekiswa kwekhwalithi | I-1500V ngephaneli ngalinye | Ukuhlolwa kwendawo | Izitifiketi zezinto zokwakha | Ukuhlolwa kwemithungo |
Impilo yesevisi | Iminyaka engu-30–40 | Iminyaka engu-8–12 ngongqimba ngalunye | Iminyaka engu-30+ | Iminyaka engu-10–15 |
Izindleko zokunakekela | Okuncane kakhulu | Okuphindaphindayo | Okubiza kakhulu ekuqaleni | Ukushintshwa |
Ukucwebezeliswa, hhayi insimbi, kunquma impilo yangempela yethangi lokugcina udaka — i-GFS enamel ene-fused enamel iletha ukumelana ne-H2S, ukubekezelela ukugqokwa kanye nomnotho weminyaka engu-30 okungenakwenziwa izinhlelo ze-epoxy nezase-liner.
Imibuzo Ejwayelekile (FAQ)
Umbuzo 1: Iyiphi into engcono kakhulu yokucwebezelisa ithangi lokugcina udaka?
I-Glass-fused-to-steel (GFS) enamel iyindinganiso yemboni: ifakwe emazingeni okushisa angu-820–930°C, ihlolwe nge-holiday test ku-1500V DC, futhi imelana ne-pH 1–14, i-H2S nokugqokwa iminyaka engu-30+ — uma kuqhathaniswa nemijikelezo yokuphinda ucwebezelise nge-epoxy engu-8–12 iminyaka.
Umbuzo 2: Kungani udaka lubhubhisa ukucwebezeliswa kwethangi?
Udaka luqukethe i-hydrogen sulfide, ama-organic acid kanye nezinhlayiya ezilimazayo ezihlasela ukumbozwa kwezindawo eziketshezini noma ezigazini. I-Fused enamel imelana nakho kokuthathu; ukumbozwa okuthambile okwenziwa endaweni kuyaguguleka, kuvuvukala, futhi kudinga ukuphinda kumbozwe.
UMBUZO 3: Kufanele kuminyene kangaki ukumbozwa kabusha kwamathangi odaka ane-epoxy lining?
Ngokuvamile njalo eminyakeni engu-8–12, kuye ngokuqukethwe kwezinto eziqinile namazinga e-sulfide. Ukumbozwa kabusha ngakunye kudinga ukukhipha, ukuqhuma kwendawo, ukumbozwa nokwelapha — amasonto okuma kanye nezindleko ezinkulu, okugwenywa yi-GFS enamel.
UMBUZO 4: Yikuphi ukuhlolwa kwekhwalithi okufanele kudlule ukumbozwa kwamathangi odaka?
Ku-GFS, wonke amaphaneli namathambo adlula ukuhlolwa kwe-holiday ye-1500V DC kanye nokuqinisekiswa kobukhulu bokumboza nokunamathela ngokuya nge-ISO 28765. Cela lawa marekhodi ebatch ngayo yonke i-oda.
