Ezimbonini ezifana nokudla kanye nemithi, ukuhlunga isitashi ngempumelelo kusuka koketshezi kuyisinyathelo esibalulekile ukuqinisekisa ikhwalithi yomkhiqizo. Ngezansi kunesingeniso esiningiliziwe solwazi olufanele lokuhlunga isitashi kusuka koketshezi.
Izixazululo Zokuhlunga Ezisebenzayo
• Indlela Yokuthulula Inhlabathi:Lena indlela elula kakhulu esebenzisa umehluko wobuningi phakathi kwesitashi noketshezi ukuze kuvunyelwe isitashi ukuthi sihlale ngokwemvelo ngaphansi kwamandla adonsela phansi. Ngesikhathi senqubo yokusila, ama-flocculant angangezwa ngokufanele ukuze kusheshiswe ukuhlanganiswa kanye nokusila kwezinhlayiya zesitashi. Ngemva kokusila, i-supernatant isuswa ngokuyikhipha noma ukuyikhipha, kushiye i-starch sediment phansi. Le ndlela ilula futhi ishibhile kodwa idla isikhathi, futhi ubumsulwa besitashi bungathinteka.
• Ukuhlunga Imidiya Yokuhlunga:Khetha imidiya yokuhlunga efanele njengephepha lokuhlunga, izikrini zokuhlunga, noma izindwangu zokuhlunga ukuze kudlule uketshezi, ngaleyo ndlela kubanjwe izinhlayiya zesitashi. Khetha imidiya yokuhlunga enobukhulu obuhlukene bemigodi ngokusekelwe kusayizi wezinhlayiya zesitashi kanye nokunemba kokuhlunga okudingekayo. Isibonelo, iphepha lokuhlunga lingasetshenziswa ekuhlungeni kwelebhu encane, kuyilapho imininingwane ehlukahlukene yezindwangu zokuhlunga ivame ukusetshenziswa ekukhiqizweni kwezimboni. Le ndlela ingahlukanisa isitashi ngempumelelo, kodwa kufanele kuqashelwe ukuvaleka kwemidiya yokuhlunga, okudingeka ishintshwe noma ihlanzwe ngesikhathi.
• Ukuhluzwa kwe-membrane:Kusetshenziswa ukuvuleka okukhethiwe kwama-membrane angangeni kahle, kuvunyelwe kuphela izinyibilikisi nama-molecule amancane, kuyilapho kugcinwa ama-macromolecule esitashi. Ama-membrane e-Ultrafiltration kanye ne-microfiltration asetshenziswa kabanzi ekuhlungeni isitashi, okufeza ukuhlukaniswa okuqinile noketshezi olunembile kakhulu kanye nokuthola isitashi esihlanzekile kakhulu. Kodwa-ke, imishini yokuhlunga i-membrane iyabiza, futhi izimo ezifana nokucindezela kanye nokushisa kudingeka zilawulwe ngokuqinile ngesikhathi sokusebenza ukuze kuvinjelwe ukungcola kwe-membrane kanye nomonakalo.
Izinhlobo Zemishini Efanelekile
• Ukucindezela Isihlungi Sepuleti Nohlaka:Ngokuhlela amapuleti nezihlungi ngokushintshana, isitashi esikuketshezi sigcinwa endwangu yokuhlunga ngaphansi kwengcindezi. Ifanele ukukhiqizwa okuphakathi nendawo, ingamelana nengcindezi ephezulu futhi isebenza kahle ekuhlungeni. Kodwa-ke, imishini inkulu, iyinkimbinkimbi ukuyisebenzisa, futhi indwangu yokuhlunga idinga ukushintshwa njalo.
• Isihlungi Sesigubhu Somshini Wokuhlanza:Ivame ukusetshenziswa ekukhiqizweni kwesitashi esikhulu, ubuso besigubhu bumbozwa ngendwangu yokuhlunga, bese uketshezi lumuncwa yi-vacuum, kushiye isitashi endwangu yokuhlunga. Inezinga eliphezulu lokuzenzakalela, amandla okukhiqiza aqinile, futhi ingasebenza ngokuqhubekayo, okwenza ifaneleke ekukhiqizweni kwezimboni ezinkulu.
• Isihlukanisi Sediski:Ukusebenzisa amandla e-centrifugal akhiqizwa ukujikeleza okusheshayo ukuze kuhlukaniswe ngokushesha isitashi noketshezi. Ezinhlelweni ezidinga ikhwalithi ephezulu yesitashi, njengokukhiqizwa kwesitashi sezinga lemithi, abahlukanisi bediski basebenza kahle kakhulu, besusa ukungcola okuncane kanye nomswakama ngempumelelo. Kodwa-ke, imishini iyabiza futhi inezindleko eziphezulu zokulungisa.
Indlela Yokusebenzisa Okuzenzakalelayo
• Uhlelo Lokulawula Oluzenzakalelayo:Sebenzisa izinhlelo zokulawula ze-PLC (Programmable Logic Controller) ezithuthukisiwe ukuze usethe kusengaphambili amapharamitha okuhlunga njengokucindezela, izinga lokugeleza, kanye nesikhathi sokuhlunga. I-PLC ilawula ngokuzenzakalelayo ukusebenza kwemishini yokuhlunga ngokuya ngohlelo oluhleliwe, iqinisekisa inqubo yokuhlunga ezinzile nephumelelayo. Isibonelo, ekucindezelweni kwesihlungi sepuleti nohlaka, i-PLC ingalawula ngokuzenzakalelayo ukuqala nokuma kwephampu yokuphakelayo, ukulungiswa kwengcindezi, kanye nokuvulwa nokuvalwa kwamapuleti okuhlunga.
• Ukuqapha Izinzwa kanye Nempendulo:Faka izinzwa zezinga, izinzwa zokucindezela, izinzwa zokuhluza, njll., ukuze uqaphe amapharamitha ahlukahlukene ngesikhathi sangempela ngesikhathi senqubo yokuhlunga. Lapho izinga loketshezi lifinyelela inani elibekiwe, ingcindezi ingavamile, noma ushintsho lokuhluza kwesitashi, izinzwa zidlulisela amasignali ohlelweni lokulawula, olulungisa ngokuzenzakalelayo amapharamitha okusebenza kwemishini ngokusekelwe kulwazi lwempendulo ukuze kufezwe ukulawula okuzenzakalelayo.
• Uhlelo Lokuhlanza Nokulungisa Okuzenzakalelayo:Ukuqinisekisa ukusebenza okuqhubekayo nokusebenza kahle kwemishini yokuhlunga, yihlomise ngohlelo lokuhlanza nokulungisa oluzenzakalelayo. Ngemva kokuphothulwa kokuhlunga, uhlelo lokuhlanza luqalwa ngokuzenzakalelayo ukuhlanza indwangu yokuhlunga, isikrini sokuhlunga, nezinye izingxenye zokuhlunga ukuvimbela insalela nokuvaleka. Ngesikhathi esifanayo, uhlelo lungahlola njalo futhi lulondoloze imishini, luhlonze futhi luxazulule izinkinga ezingaba khona ngesikhathi esifanele.
Ukwazi izixazululo ezisebenzayo zokuhlunga isitashi kusuka koketshezi, izinhlobo zemishini ezifanele, kanye nezindlela zokusebenzisa ngokuzenzakalela kubaluleke kakhulu ekuthuthukiseni ikhwalithi kanye nokusebenza kahle kokukhiqizwa kwesitashi. Kuthenjwa ukuthi okuqukethwe okungenhla kunganikeza izinkomba ezibalulekile kubasebenzi abafanele futhi kufake isandla ekuthuthukisweni komkhakha.
