Imisebenzi yezimboni ivame ukubhekana nezimo ezimanzi ezicindezela amamitha okugeleza endabuko emikhawulweni yazo—cabanga ngamanzi amdaka agcwele udaka, uketshezi olupholisa olunamabhamuza, amakhemikhali aqothulayo, noma uwoyela oqinile. Sekungamashumi eminyaka, amamitha okugeleza e-ultrasonic elwela ukugcina ukunemba kulezi zimo, ephazanyiswa ukuphazamiseka kwesignali, ukuguguleka kwezingxenye, kanye nokuzivumelanisa nezimo okulinganiselwe. Kodwa-ke, ukuthuthuka kwamuva kwezobuchwepheshe kuguqule la madivayisi aba izixazululo ezinokwethenjelwa ngisho nasezimweni ezinzima kakhulu, kubhekana namaphuzu abalulekile obuhlungu ngokusebenzisa izinto ezintsha ekwakhiweni, ekuzweleni nasekucutshungulweni kwedatha.
Enye yentuthuko enomthelela omkhulu ukushintshela ekucushweni kwe-transducer enezindlela eziningi. Amamitha amadala e-ultrasonic ayethembele endleleni eyodwa yesignali phakathi kwama-transducer amabili, ehluleka kalula uma ivinjwe yizinto eziqinile noma iphazanyiswa yi-turbulence. Amamodeli esimanje anezindlela eziningi—ahlonyiswe ngama-transducer angu-4 kuya kwangu-8 ahlelwe ngamaphethini anqamulayo noma ajikelezayo—anqoba lokhu ngokuthatha idatha yokugeleza kusuka kuma-engeli amaningi. Isibonelo, isitshalo samakhemikhali esicubungula amanzi angcolile anezinto eziqinile ezimiswe ngo-15% sabona ukunemba kuthuthuka kusuka ku-±3% (ngamamitha anezindlela eyodwa) kuya ku-±0.8% ngemuva kokuthuthukela kumitha ye-ultrasonic enezindlela eziyisithupha. Ngisho noma indlela eyodwa ifihliwe yi-sludge, amanye ayaqhubeka nokunikeza ukufundwa okunembile, okususa isidingo sokulungiswa kabusha njalo.
Enye intuthuko ebalulekile ukucubungula isignali eguquguqukayo, enikwe amandla yi-algorithms eqhutshwa yi-AI. Amabhamuza noma igesi eqediwe ngaphambili kwakuyinto ebalulekile kumamitha e-ultrasonic, njengoba ebonakalisa amaza omsindo futhi ehlanekezela izibalo zokugeleza. Amamitha anamuhla asebenzisa ukuhlaziywa kwesignali yesikhathi sangempela ukuhlukanisa phakathi kwamabhamuza adlulayo (angenangozi) kanye namaphakethe egesi aqhubekayo (ayinkinga). Alungisa ngokuzenzakalelayo imvamisa yesignali—ashintshela kumaza aphansi (0.5–1 MHz) ukuze angene emanzini anomswakama, isibonelo—noma akhulise izimpawu ezibuthakathaka ukuze alondoloze ukuvumelana. Uhlelo lwamanzi okupholisa lwesitshalo sikagesi, olwalubhekene namaphutha ahlobene namabhamuza angaphezu kuka-20 ngenyanga, manje luqopha ngaphansi kwamabili ngemva kokufaka amamitha ngalobu buchwepheshe.
Ukusungula izinto ezintsha zesayensi yezinto ezibonakalayo nakho kuqinise amamitha e-ultrasonic ngokumelene nokugqwala nokuklwebheka. Ama-transducer endabuko, enziwe ngensimbi engagqwali ejwayelekile, agqwala ngokushesha kuketshezi olune-acid noma olubangela ukungcola (isb., i-pH 2 yokumba amanzi angcolile). Amamodeli amasha asebenzisa ama-transducer e-ceramic noma e-Hastelloy C-276: i-ceramic imelana nokugqwala nokuklwebheka kusuka ezintweni eziqinile eziklwebhekayo, kuyilapho i-Hastelloy iphatha amakhemikhali aqine njenge-sulfuric acid. Ngokufanayo, ama-linings emitha ashintshe kusuka enjolobeni kuya ku-PTFE noma ku-ETFE, izinto ezimelana namazinga okushisa afinyelela ku-150°C futhi zimelana nokuwohloka okuvela ezinyibilikisini ezinzima. Umsebenzi wokumba ubike ukuthi amamitha e-ceramic-transducer ahlala isikhathi eside kathathu kunalawo ensimbi engagqwali emigqeni yawo yamanzi angcolile ane-acid.
Uketshezi oluhamba kancane kanye nolunamandla aphezulu, olwake lwabangela amamitha e-ultrasonic ukuthi abhalise ukufundwa okungamanga "okungu-zero", manje seluzuza ekusebenzeni kahle kwejubane eliphansi. Ubuchwepheshe be-Micro-pulse—okuthumela ukuqhuma kwe-ultrasound okufushane nokuvame kakhulu—buvumela ukutholakala kwamazinga okugeleza aphansi njengo-0.01 m/s, okubalulekile ezinqubweni zeqembu njengokukhiqiza imithi. Kuketshezi olunamandla aphezulu (isb., uwoyela wemoto ongu-10,000 cP), amamitha manje afaka ama-algorithms okunciphisa i-viscosity alungisa izibalo ngokusekelwe kudatha yokushisa yesikhathi sangempela (njengoba i-viscosity yehla ngokushisa). Isitshalo sokugcoba sithole leli phutha lokulinganisa elincishisiwe lamafutha asindayo kusuka ku-±4% kuya ku-±1.2%.
Okokugcina, izici zokuzihlola kanye nokuqapha kude zinciphise imithwalo yokulungisa. Amamitha e-ultrasonic anamuhla aqhubeka nokulandelela izilinganiso zokusebenza—amandla esignali, impilo ye-transducer, izinga lokushisa—futhi athumela izexwayiso zezinkinga ezifana nokungcola noma ukuguguleka kwezingxenye. Amanye afaka ngisho nokuzihlanza nge-ultrasonic: ama-pulse amafushane, anamandla aphezulu akhipha amadiphozithi okukhanya kuma-transducer. Isitshalo sokwelapha amanzi amdaka esisebenzisa la mamitha sinciphise isikhathi sokulungisa ngo-60%, njengoba ochwepheshe bebhekana nezinkinga ngendlela efanele esikhundleni sokusabela ekwehlulekeni.
Lezi zintuthuko zichaze kabusha lokho okungenziwa amamitha okugeleza e-ultrasonic, ziguqula izindawo zoketshezi ezazike zaba yinselele zaba yizindawo ezilawulekayo. Ngokuhlanganisa ukuzwa ngezindlela eziningi, ama-algorithms aguquguqukayo, izinto ezihlala isikhathi eside, kanye nokuqapha okuhlakaniphile, amamitha e-ultrasonic anamuhla aletha ukunemba, isikhathi eside, kanye nokusebenza kahle lapho amadivayisi endabuko ehluleka khona. Ezimbonini ezithembele ekulinganisweni kokugeleza okunembile—kusukela ekucutshungulweni kwamakhemikhali kuya ekuphathweni kwamanzi angcolile—lobu buchwepheshe abugcini nje ngokuthuthukiswa, kodwa buyithuluzi elibalulekile lokusebenza okuthembekile.
