iindaba

I-Bubbling, ubuchule obubalulekileyo kunye obusetyenziswa ngokubanzi kwi-homogenization enyanzelweyo, ngokubonakalayo nangokunzima kunempembelelo kwiinkqubo ze-fining kunye ne-homogenization yeglasi etyhidiweyo. Nalu uhlalutyo oluneenkcukacha.

1. UmGaqo weTekhnoloji yokuBhabhula

Ukubhubhuza kubandakanya ukufaka imiqolo emininzi yamaqamza (imilomo) emazantsi eziko lokunyibilika (ngokuqhelekileyo kwindawo yokugqibela yendawo yokunyibilika okanye indawo yokucolwa). Irhasi ethile, edla ngokucinezelwa umoya, initrogen, okanye igesi engasebenziyo, itofwa kwiglasi enyibilikisiweyo yobushushu obuphezulu ngamaxesha athile okanye ngokuqhubekayo. Irhasi iyanda kwaye inyuka ngeglasi etyhidiweyo, idala iikholomu zamaqamu anyukayo.

2. Impembelelo yokuGqubha kwiNkqubo yokuFina (Kakhulu iNgcono)

Ukubhubhuza ikakhulu kunceda ukususa amaqamza erhasi, ngaloo ndlela kucacisa iglasi.

Ukukhuthaza Ukususwa kweBhabhula

Isiphumo sokutsala: Indawo yoxinzelelo oluphantsi ifom emva kwamaqamza amakhulu, anyukayo, edala "impembelelo yokumpompa." Oku kutsala, kuqokelela, kwaye kudibanisa amaqamza amancinci ukusuka kwiglasi etyhidiweyo ejikelezileyo, iwathwalele phezulu ukuze agxothwe.

UkuNcitshiswa kweGas Ukunyibilika: Igesi ejojowe, ngakumbi igesi ye-inert, inokunciphisa iigesi ezinyibilikileyo kwiglasi etyhidiweyo (umz., SO₂, O₂, CO₂), ukunciphisa uxinzelelo lwabo. Oku kwenza kube lula ukukhutshwa kweegesi ezinyityilisiweyo kumaqamza anyukayo.

Ukuncitshiswa kweLocal Supersaturation: Amaqamza anyukayo abonelela nge-gas-liquid interface esele yenziwe, yenza kube lula kwi-supersaturated dissolved gases ukuba inyibilike kwaye isasazeke kwi-bubbles.

Indlela yokuFina emfutshane: Iintsika zeqamza ezinyukayo zisebenza "njengemizila ekhawulezayo," ekhawulezisa ukufuduka kweegesi ezinyityilisiweyo kunye namaqamza amancinci ukuya kumphezulu.

Ukuphazamiseka koMaleko wegwebu: Kufuphi nomphezulu, amaqamza anyukayo anceda ukwaphula umaleko oshinyeneyo wogwebu olunokuthintela ukugxothwa kwerhasi.

Iziphumo ezinokuthi zimbi (zifuna ulawulo)

Intshayelelo yeeBhabhula eziNtsha: Ukuba iiparamitha zokubhubhuza (uxinzelelo lwerhasi, ukuphindaphinda, kunye nobunyulu) zilawulwa ngokungafanelekanga okanye ukuba imilomo ivaliwe, inkqubo inokwazisa amaqamza angafunekiyo, amancinci. Ukuba la maqamza akanakususwa okanye anyibilike kwisohlwayo esilandelayo, aba ziziphene.

UKhetho lweGesi engafanelekanga: Ukuba igesi etotiweyo iphendula ngokungathandekiyo ngeglasi etyhidiweyo okanye iigesi ezinyityilisiweyo, inokuvelisa i-gases enzima kakhulu ukususa okanye i-compounds, ithintele inkqubo yokucoca.

3. Impembelelo yokuGqubha kwiNkqubo yeHomogenization (Kakhulu iNgcono)

Ukubhubhuza kakhulu kuphucula ukuxubana kunye ne-homogenization yeiglasi etyhidiweyo.

I-Convection eyomeleziweyo kunye nokuKhuthaza

Ukujikeleza okuthe nkqo: Njengoko iikholomu zeqamza zinyuka, ukuxinana kwazo okuphantsi xa kuthelekiswa neglasi etyhidiweyo kudala ukuhamba okunamandla ukuya phezulu. Ukuzalisa iglasi ekhulayo, iglasi ejikelezileyo kunye nesezantsi iqukuqela ngokuthe tye ukuya kwikholamu yebhamu, idala amandla anamandla.ukujikeleza ngokuthe nkqookanyeukuhambisa. Le convection inyanzeliswa ikhawulezisa kakhulu ukuxubana othe tye kweglasi enyibilikisiweyo.

Ukucheba Ukuxuba: Umahluko wesantya phakathi kwamaqamza anyukayo kunye neglasi etyhidiweyo ejikelezileyo ivelisa amandla okucheba, ikhuthaza ukuxubana phakathi kwemigangatho emeleneyo yeglasi.

UHlaziyo lwesiNxulumanisi: Ukuphazamiseka okuvela kumaqamza anyukayo ngokuqhubekayo kuhlaziya ujongano lonxibelelwano phakathi kweglasi yeengoma ezahlukeneyo, ukuphucula ukusebenza kakuhle kwe-molecular diffusion.

Ukuphazamiseka kweStratification kunye neStriations

I-convection eyomeleleyo iqhawula ngokufanelekileyoikhemikhali okanye i-thermal stratificationkwayeiindlelaokubangelwa yiyantlukwano yoxinaniso, ukuthamba kobushushu, okanye ukondla okungalinganiyo. Ibandakanya ezi zingqimba kwi-flow engundoqo yokuxuba.

Oku kunceda ngokukodwa ekupheliseni"indawo ezifileyo"ezantsi itanki, ukunciphisa crystallization okanye inhomogeneity kakhulu okubangelwa stagnation ixesha elide.

Ukuphucula ukusebenza kakuhle kwe-Homogenization

Xa kuthelekiswa nokuhamba kwendalo okanye ukugeleza kweqondo lobushushu, ukuhanjiswa okunyanzeliswayo okuveliswa kukubhubhuza kuneukuphakama kwamandla aphezulu kunye nokufikelela ngokubanzi. Oku kunciphisa kakhulu ixesha elifunekayo ukufezekisa inqanaba elifunekayo le-homogeneity okanye ukuphumeza ukufana okuphezulu ngexesha elifanayo.

Iziphumo ezinokuthi zimbi (Funa Ingqalelo)

Ukhukuliseko lweMathiriyeli oluLawulayo: Ukuhamba ngesantya esiphezulu samaqamza anyukayo kunye noguqulo olunzulu abalubangelayo kunokubangela ukhukuliseko olunamandla kunye nokuhlwa komphantsi wetanki kunye nezixhobo ezichasayo ezisecaleni eludongeni, zicuthe ubomi beziko. Oku kunokwazisa iimveliso zokhukuliseko kwiglasi etyhidiweyo, ukudala imithombo emitsha ye-inhomogeneity (amatye, i-striations).

Ukuphazamiseka kweePatheni zokuHamba: Ukuba ubume bendawo yeqamza, ubungakanani beqamza, okanye ukuphindaphindeka ayilwanga kakuhle, inokuphazamisana noqobo, ubushushu obuluncedo kunye neendawo zokuqukuqela kwendalo ngaphakathi kwetanki yokunyibilika. Oku kunokudala imimandla emitsha engalinganiyo okanye i-vortices.

4. Iiparamitha eziPhambili zoLawulo lweTekhnoloji yeBubbling

Isikhundla sokuGqamza: Ngokuqhelekileyo kwinxalenye yokugqibela yendawo yokunyibilika (ukuqinisekisa ukuba izinto ezikrwada zinyibilika ubukhulu becala) kunye nommandla wokucoca. Isikhundla kufuneka sikhethwe ukwandisa ukuhamba kunye neendawo zokushisa.

Ukukhetha igesi: Izinketho ziquka umoya (ixabiso eliphantsi, kodwa iimpawu ze-oxidizing ezinamandla), i-nitrogen (inert), kunye neegesi ezingenayo njenge-argon (i-inertness engcono kakhulu, kodwa iyabiza). Ukhetho luxhomekeke kukwakheka kweglasi, imeko ye-redox, kunye neendleko.

Ubungakanani bebhabhula: Eyona nto ilungileyo kukuvelisa amaqamza amakhulu (iimilimitha ezininzi ukuya kwisentimitha ububanzi). Amaqamza amancinci anyuka kancinane, anesiphumo sokufunxa esibuthathaka, kwaye asenokungakhutshwa lula, abe sisiphene. Ubungakanani beBubble bulawulwa yi-nozzle design kunye noxinzelelo lwegesi.

UkuBhabhuza rhoqo: Ukubhubhudla ngamaxesha athile (umzekelo, kanye ngemizuzu embalwa) kudla ngokusebenza ngakumbi kunokuqhwiza rhoqo. Idala ukuphazamiseka okunamandla ngelixa ivumela ixesha lokuba i-bubbles ikhutshwe kunye neglasi ukuzinza. Ukuqina (izinga lokuhamba kwegesi kunye noxinzelelo) kufuneka lihambelane nobunzulu beglasi kunye ne-viscosity.

UYilo lweNdawo yokuGqamza: Ukulungelelanisa imiqolo emininzi kwipatheni edibeneyo egubungela yonke ububanzi betanki iqinisekisa ukuba i-convection ifikelela kuzo zonke iikona, ukuthintela "imimandla efileyo." Isithuba kufuneka siphuculwe.

Ukucoceka kwegesi: Ukungcola okufana nokufuma okanye ezinye iigesi kufuneka kuphetshwe ukunqanda iingxaki ezintsha.

Ukuqukumbela, ukubhubhuza bubuchwephesha obubalulekileyo obufaka irhasi kwiglasi enyibilikisiweyo ukwenza ukujikeleza okuthe nkqo kunye nokuphazamiseka. Oku akukhawulezi ukukhawuleza inkqubo yangaphakathi yokucolwa, ukunceda amaqamza amancinci namakhulu adibane kwaye agxothwe, kodwa aphinde aphule ngokufanelekileyo imichiza kunye ne-thermal inhomogeneous layers kunye nokuphelisa imimandla efileyo. Ngenxa yoko, iphucula kakhulu ukusebenza kakuhle kwe-homogenization kunye nomgangatho weglasi. Nangona kunjalo, ulawulo olungqongqo kwiiparamitha eziphambili ezinjengokukhethwa kwegesi, indawo, ukuphindaphinda, kunye nobukhulu beqamza kubalulekile ukunqanda ukungenisa iziphene ezintsha zeqamza, ukhukuliseko olubi lwe-refractory, okanye ukuphazamisa indawo yokuhamba. Ke ngoko, ngelixa inemiqobo enokuthi ibekho, i-bubbling yitekhnoloji ephambili enokuthi yenziwe ukuba iphucule kakhulu ukwenziwa kweglasi.
