Emashini okukhiqiza amadivaysi amasha okugcina amandla afana ne-Lithium - I-Ion ne-Sodium - Amabhethri e-Ion, ukulungiswa kwe-battery slurry kuyisinyathelo esingukhiye ekunqumeni ukusebenza komkhiqizo wokugcina. Ibhethri Slurry liqukethe ingxube yezinto ezisebenzayo, ama-ejenti aqhubayo, ama-beinders kanye nama-solvents ngezilinganiso ezithile. Ukuhlakazeka kwayo okufanayo kanye negwebu - Izakhiwo zamahhala zihlobene ngqo nekhwalithi ye-electrode coating. Ukuba khona kwama-bubble ku-slurry kungaholela ekulimaleni okufana nama-mainholes kanye nama-expelos amashidi we-elektrodi, kunciphisa ukuqina kwe-electrode, okuthinta amandla okuphehla ibhethri, futhi ngisho nokuphepha komjikelezo. Izindlela zendabuko ezihlambalazayo, ezinjenge-vacuum decouming kanye nokungezwa kwama-decoamers amakhemikhali, akusebenzi kahle futhi kunamandla - noma kungenisa ukungcola okuthinta ukusebenza kwebhethri. Ngokumelene nalesi sangemuva, ubuchwepheshe be-ultrasonic, ngokusebenza kwayo okuphezulu, ubungane bezemvelo, kanye nokungcoliswa kwezesibili, sekuyisixazululo esisha se-bettery slurry desouming.
II. Umgomo oyisisekelo we-ultrasonic yebhethri le-slurry desouming
Ubuchwepheshe be-Ultrasonic Defenualing bathobela imiphumela embaxambili ye-cavitation kanye nokudlidliza ukudluliselwa ekuqedeni kahle ama-bubble ku-battery slurry. Izimiso zalo ezibalulekile zingahlukaniswa ngezinqubo ezintathu ezibalulekile:
1. I-Cavitation Eccounce: "Micro - ukuqhuma" Ukubhujiswa kwe-Bubble
Lapho amagagasi e-ultrasonic (ngokuvamile avamale kwe-20KHZ - 1MHz) asetshenziswa kuhlelo lwe-slurry yebhethri, akhiqiza ukuguquguquka kwengcindezi yezikhathi ezithile ngaphakathi kwe-slurry - ukushintshanisa phakathi kwezigameko phakathi kwezikhathi zokucindezela kanye nezigaba ze-rarefaction. Ngesikhathi sesigaba se-rarefaction, ingcindezi eseSlurry idonsa kakhulu, yakha inani elikhulu le-tiny vacuum cavities (ama-bubble we-cavitation). Lawa ma-bubble we-cavitation adonsa ngokushesha ama-bubble azungezile (kufaka phakathi i-micron - ngisho ne-nanometer - ama-bubble asayizi), okwenza ivolumu lalo lithuthuke ngokuqhubekayo. Kamuva, ngesikhathi sesigaba sokucindezela, ingcindezi eseSlurry ikhuphuka ngokushesha. Ngaphansi kwengcindezi, ama-bubble e-cavitation asheshe asheshe asebenze futhi afaka, akhiqize ingcindezi ephezulu yasendaweni (kuze kube yizinkulungwane zezulu) kanye namazinga okushisa aphezulu (aze afike ezinkulungwaneni zama-degrees Celsius), ahambisana namagagasi ashaqekile ashaqekile kanye nama-Jets. Lokhu "okuncane - ukuqhuma" - njengenqubo yokuqhuma ngokuqondile kwephula ama-bubble adderbed ku-bubble nuclei omncane kakhulu. Lawa ma-nuclei, abe mancane kakhulu ukuba alondoloze ukuqina, masinyane ahlangane ne-slurry ezungezile noma abalekele ohlelweni, uzuze umphumela wokungcolisa.
2. Ukuhanjiswa okudlidliza: Ukufuduka okuqondisiwe kwe-bubble futhi uphunyuke
Lapho i-ultrasound isakaza ngokusebenzisa ama-slurry, futhi ifaka ukuvezwa okuphezulu - Ukudlidliza imvamisa kuma-molecule nezinhlayiya ngaphakathi kwe-slurry (imvamisa yokudlidliza kufana nemvamisa ye-ultrasound). Lokhu kudlidliza kuphazamisa ukulingana okuzinzile kwama-bubble ngaphakathi kwe-slurry. Ama-Bubble phambilini anamathele ebusweni bezinhlayiya ezibonakalayo ezisebenzayo noma "eboshwe" ngokusobala kwe-slurry ukuthola amandla e-kinetic ngaphansi kwesenzo sokudlidliza, ukugqashula emaphoyinti abo angenalutho. Ngaphezu kwalokho, ukudlidliza kunciphisa ukubonakala kwasendaweni kwe-slurry, ukunciphisa ukumelana nokufuduka kwe-bubble nokusheshisa okuhlangene kwe-bubble futhi kuphunyuke. Lokhu okudlidliza - Umphumela wokufuduka osizayo ubaluleke kakhulu ku-High - I-Viscosity yebhethri Slurries (njenge-Lithium - I-Ion Battery Calloode Slurode, okuvame ukuba ne-viscosity ka-1000 - ama-5000MPA · Ingaxazulula ngempumelelo inkinga ye-bubble yokuphunyuka kusuka ekuphakameni - I-Viscosity Slurries ngesikhathi sokufa kwe-vacuum yendabuko.
3. Ukuhlakazeka kwesibili: Ukuvimbela ukubuyekezwa kwe-bubble
Ngokungafani nama-decoamers amakhemikhali, ubuchwepheshe be-ultrasonic hhayi kuphela ama-degoams kodwa futhi nama-spression amabanga aphansi izinhlayiya eziseleni. I-Ultrasonic Vibration kanye ne-Cavitation Effect Break up noma yiziphi izinto ezisebenzayo ezisebenzayo kanye nama-acent acent aggregates ku-slurry, edala ukuhlakazeka okufanayo. Lokhu kudluliswa kunciphisa "ama-voids" akhiwa yizinhlayiyana angglomeration. Lezi void zingabamba kalula umoya futhi zithole ama-bubble amasha. Ukuhlakazeka okufanayo kwezinhlayiya kugcwalisa lezi zikhala, kunciphisa amathuba okuba yisizukulwane se-bubble sesibili emthonjeni. Lokhu kufezekisa imiphumela emibili yokuhlakazwa okuthi "ukungcolisa +," ngcono kakhulu ukuthuthukisa ikhwalithi ye-slurry.
III. Izinzuzo ezibalulekile zobuchwepheshe be-Ultrasonic defoaling
Uma kuqhathaniswa nezindlela zendabuko zokuhlambalaza, ubuchwepheshe be-ultrasonic bukhombisa izinzuzo zezobuchwepheshe ezibalulekile kubhethri le-slurry desouming, ezingafingqiwe ngamaphuzu amane alandelayo:
1. Ukusebenza okuphezulu okuchazayo kanye nobubanzi bokusebenza
I-Ultrasonic Devoaming inesikhathi esifushane (imvamisa ukwelashwa okukodwa kuthatha imizuzu embalwa kuphela kuze kube yimizuzu eyishumi, ngaphansi kwamashumi amaminithi amaminithi adingekayo ku-vacuum decouming) futhi angasusa ama-bubble amancane (kufaka phakathi ama-bano ama-bubble) okunzima ukuwakhipha ngezindlela zendabuko. Noma ngabe kuphansi - I-viscosity anode slurry (efana ne-graphite slurry ye-lithium - ukuphakama okuphezulu) Ama-slurries asebenzayo avela kusuka ku-100 kuye ku-10,000 mpla, emboza ama-slurry ama-slurry wamabhethri okugcina amandla e-Maveam. 2. Luhlaza nokungcola - Mahhala, ukuqinisekisa ukusebenza kwebhethri
I-Ultrasonic Devoaming yindlela yokungcolisa ngokomzimba edinga ama-ejenti amakhemikhali okuhlanza, ngokuyisisekelo ukugwema umthelela omubi wokuhlehlisa ama-agent desigue ekusebenzeni kwebhethri. Izakhi ze-organic kuma-decoamers endabuko zamakhemikhali zingasabela ngezinto zokwakha ezisebenzayo ze-electrode noma ukubola ngesikhathi sokuhamba ngebhayisikile, ukukhiqiza amagesi futhi kuholele ekuwohlokeni kwamakhono. Ngokwesinye ubuchwepheshe be-Ultrasonic, ngakolunye uhlangothi, kuphela ama-bubble ngokomzimba ngaphandle kokuguqula ukwakheka kwamakhemikhali kwe-slurry, ngaleyo ndlela kwandise ukusebenza kwebhethri nokuphepha kwebhethri. Ngaphezu kwalokho, lobu buchwepheshe bungawukhiqizi amanzi amdaka noma igesi yokuqeda amandla, ukuhambisana ne- "Green Delited" Development Development of the New Energy Favolic.
I-3. Ukuhambisana okuqinile kwenqubo nokuhlanganiswa okulula emigqeni yokukhiqiza
Imishini yokungcolisa ye-ultrasonic iyinkimbinkimbi futhi ingahlanganiswa nezimo emigqeni yokukhiqiza yebhethri ekhona ye-Slurry yokulungiselela. Ingasetshenziswa njengeyunithi ye-standalone defoaling, efakwe phakathi kwethangi lokuxuba le-slurry kanye nomshini wokuhlanganisa. Ingahlanganiswa nedivaysi yokuxuba ukuze kwakhiwe uhlelo oluhlanganisiwe "lokuxuba +" uhlelo ", ukunika amandla ukulungiselela okufingqiwe okukodwa kanye nokuklanywa. Ngaphezu kwalokho, amapharamitha we-ultrasonic wemishini (efana nokuvama, amandla, kanye nesikhathi sokucubungula) angashintshwa ngokunembile ngohlelo lokulawula okuzenzakalelayo, okuvumela ukuncibilikisa ukuncibilikisa ngokususelwa ku-slurries ahlukile (njengohlobo olusebenzayo, ukuvumelanisa kanye nokuqukethwe kwe-solids).
4. Yehlisa izindleko zokukhiqiza kanye nokuqina okuthuthukile kokukhiqiza
Mayelana nende - Izindleko zokusebenza kwethemu, ukungcola kwe-ultrasonic kudla amandla amancane kunokuthi i-vacuum desoum (edinga izinga eliphakeme eliphakeme futhi lisebenzisa amandla amaningi), bese liqeda izindleko zokuthengwa kwezimpahla zamakhemikhali. Ngokuya ngokuqina kokukhiqizwa, ukungcola kwe-ultrasonic kunikeza umphumela ozinzile wokungcolisa, okuthintwe okuncane ngokuhlukahluka kwe-slurry batch kanye nezinguquko ekushiseni okukhona kanye nomswakama. Lokhu kunciphisa isilinganiso se-electrode scrap esibangelwa ukungcola okungaphelele, ukuthuthukisa isivuno nokuqina komugqa wokukhiqiza. Idatha yohlelo lokusebenza evela kwabakhiqizi bebhethri ibonisa ukuthi ukusetshenziswa kobuchwepheshe be-ultrasonic defoaling kuncishisiwe amanani entengo kagesi nge-30% - Impilo yebhethri yebhethri (i-1c yokuphuma) ngo-10% - I-12%.
