I-Ultrasonic Degasification neDe-Aeration

I-Ultrasonic degasification kanye ne-deaeration kuyindlela enamandla kakhulu yezindlela zendabuko zokunciphisa uketshezi okubandakanya ukubilisa, ukunciphisa ingcindezi yokuhlanza, noma ukusakaza ngamagesi angenawo amandla. Lezi zindlela zendabuko zokunciphisa zivame ukuza nezinkinga ezifana nokuwohloka okushisayo (ngenxa yokushisa), ukucubungula okudla isikhathi namandla kanye / noma ukukhishwa kwegesi okunganele. I-Ultrasonic degassing isuselwa kumgomo wokusebenza we-acoustic cavitation. Lapho amagagasi e-ultrasound enamandla amakhulu ahlanganiswa abe uketshezi, uketshezi luyacindezelwa futhi lwandiswe phakathi nemijikelezo yengcindezi ephezulu nengaphansi, ngokulandelana. Ngesikhathi semijikelezo enengcindezi ephansi, kudalwa amabhamuza we-vacuum (okuthiwa ama-bubble cavitation), akhula ngaphezu kwemijikelezo eminingana yengcindezi. Phakathi naleyo mizungezo yokukhula kwamabhamuza, amagesi ancibilikile asoketshezi angena kubhamu elingenalutho, ukuze ibhamu elingenalutho liguquke libe amabhamuza egesi akhulayo. Ngaphezu kwalokho, ama-micro-turbulences nama-jets we-liquid abangela ukuphazamiseka okukhulu nokudluliswa okukhulu. Lezi zimo ezikhiqizwe nge-ultrasonically zidala i-gas bubble coalescence, okuwukuhlanganiswa kwamabhamuza amancane ancibilikisiwe egesi abe ngamabhamuza amakhulu egesi, asheshe akhuphukele ngaphezulu kuketshezi, lapho ashiya khona uketshezi.
Izinguquko zokushisa ezibangelwa ukudlidliza kwe-ultrasonic kanye ne-cavitation zigcinwa ezindaweni ezincane kakhulu zendawo futhi izinga lokushisa lenyuka kumthamo ophelele linganakekelwa ngoba aliphazamisi ikhwalithi yomkhiqizo.
Ngokuya ngevolumu, i-viscosity negesi inclusions ye-liquid noma i-slurry, i-ultrasonic de-aeration ingaqhutshwa njengenqubo ye-batch noma emgqeni. Iphenyo enamandla amakhulu e-ultrasonic ikhipha i-acoustic cavitation kulolo ketshezi, ukuze uketshezi lususwe kahle.

Ukwehlukaniswa okuthuthukisiwe kwe-Ultrasonically

Uketshezi okusakazwa ngegesi engena ngaphakathi (okwaziwa nangokuthi ukuhlanzwa kwegesi ngaphakathi) kuyindlela ejwayelekile yokwelapha ukukhipha amagesi angafuneki njenge-oxygen ne-carbon dioxide kulolo ketshezi. Ngokusebenzisa okwehlukanisa, i-nitrogen, i-argon, i-helium namanye amagesi we-inert asetshenziswa kakhulu. Ukugcoba isixazululo nge-high-purity (okujwayelekile okuyi-inert) igesi kungakhipha okungafuneki, amagesi avele ancibilike anjenge-oxygen ne-carbon dioxide. Inqubo yokuncipha incike ekudlulisweni kwenqwaba futhi uqobo iyinqubo ehamba kancane. Ngiyalela ukuqinisa ukusakazeka ngamagesi angenawo amandla, isixazululo segesi eliwuketshezi luvame ukufutheliswa ngamandla futhi liphuphume isikhathi eside. I-Ultrasonication inqubo yokuqinisa i-degasification, ethuthukisa ukudluliswa kwesisindo futhi ngaleyo ndlela ihlukane kakhulu. Lapho amagagasi e-ultrasound enamandla amakhulu ahlanganiswa abe uketshezi noma ama-slurries, kwenziwa amabhamuza e-cavitation. Lawa maqebelengwane e-cavitation aqhekeza amabhamuza egesi amakhulu ahlanza amabhamuza amancane bese ewasakaza ngendlela efanayo, okuholela emiphumeleni yokuhlanza esheshayo nehlanzekile. Ukuyaluza okukhulu nokuxokozela okwenziwe yi-ultrasonication kuthuthukisa ukudluliswa kwesisindo samanzi kagesi futhi ngaleyo ndlela kususwe ngokushesha amagesi angafuneki.
Ukuze kusheshiswe futhi kwenziwe inqubo yokusabalalisa isebenze kahle, i-ultrasonics esebenza kahle kakhulu isetshenziselwa ukwenza ngcono ukusebenza kokudlulisa okukhulu phakathi kwegesi noketshezi. Imiphumela ye-sonomechanical eyenziwe yi-acoustic cavitation ifaka phakathi ingcindezi yendawo kanye nokwehluka kwamazinga okushisa, ama-microturbulence kanye nokuphazamiseka. Le mikhosi ithuthukisa ukusebenza kwe-degassing ngokunikela ekwandeni kokudluliswa kobunzima obungafani ngenxa yokuqhekeka kwamabhamuza, ukusabalalisa kanye nokwanda okulandelayo kwendawo yokuhlangana, okugcina kuholele ekususweni okusheshayo kwamagesi avalelekile kulolo ketshezi.
Ukufeza imiphumela oyifunayo ye-outgassing, i-high-power ultrasonication iyadingeka. Lapho uketshezi lusindiswa ngegesi engena ekugelezeni kwezigaba ezimbili, ukusakazwa okulungisiwe kuyadingeka ukukhulisa isilinganiso sokudluliswa nokususwa kwamagesi ancibilikile. Ukufaka ukusabalalisa okulungisiwe kungaba nzima ngoba amabhamuza egesi abambekile futhi ancibilikile avame ukugwema ukungena enkambeni ye-ultrasonic cavitation ngamandla aphansi. Kodwa-ke, ngamandla aphakeme (angaphezulu kuka-300 W / cm2 ngo-approx. Ama-bubbles kagesi angama-20 kHz) awasayigwema indawo ye-cavitation futhi ahlukaniswa ngamabutho we-sonomechanical.
