I-Bubbling, indlela ebucayi nesetshenziswa kabanzi ekuhlanganisweni okuphoqelelwe, kunomthelela kakhulu futhi ngokuyinkimbinkimbi ezinqubweni zokucwenga kanye ne-homogenization yengilazi encibilikisiwe. Nakhu ukuhlaziya okuningiliziwe.

1. Isimiso seBubbling Technology

Ukubhubhudla kuhlanganisa ukufaka imigqa eminingi yamabhamuza (imibhobho) ngaphansi kwesithando somlilo esincibilikayo (imvamisa engxenyeni yokugcina yendawo yokuncibilika noma indawo yokuncibilika). Igesi ethile, ngokuvamile umoya ocindezelweyo, i-nitrogen, noma igesi engasebenzi, ijovwa engilazini encibilikisiwe enezinga lokushisa eliphezulu ngezikhathi ezithile noma ngokuqhubekayo. Igesi iyakhula futhi ikhuphuke ngengilazi encibilikisiwe, idale amakholomu amabhamuza akhuphukayo.

2. Umthelela Wokubhubhudla Enqubweni Yokuhlawuliswa (Okuhle Ngokuyinhloko)

Ukubhubhudla kusiza ikakhulukazi ukususa amabhamuza egesi, ngaleyo ndlela kucacise ingilazi.

Iphromotha Ukususwa Kwebhamuza

Umphumela Wokudonsa: Indawo enengcindezi ephansi yakha ngemuva kwamabhamuza amakhulu, akhuphukayo, okudala "umphumela wokupompa." Lokhu kudonsa, kuqoqe, futhi kuhlanganise kahle amabhamuza amancane asuka engilazini encibilikisiwe ezungezile, awayise phezulu ukuze axoshwe.

Ukuncibilika Kwegesi Encishisiwe: Igesi ejovwe, ikakhulukazi igesi engasebenzi, ingancibilikisa amagesi ancibilikisiwe engilazini encibilikisiwe (isb, SO₂, O₂, CO₂), inciphise ukucindezela kwawo okuyingxenye. Lokhu kusiza ukuqedwa kwamagesi ancibilikisiwe kumabhamuza akhuphukayo.

I-Supersaturation Encishisiwe Yasendaweni: Amabhamuza akhuphukayo anikeza isixhumi esibonakalayo esenziwe ngomumo soketshezi lwegesi, okwenza kube lula ngamagesi ancibilike ane-supersaturated ukuthi ancibilike futhi asakazeke kumabhamuza.

Indlela Yokuqeda Efushanisiwe: Amakholomu ebhamuza akhuphukayo asebenza “njengamathrekhi asheshayo,” asheshisa ukuthuthela kwamagesi ancibilikile namabhamuza amancane abheke phezulu.

Ukuphazamiseka Kwesendlalelo Segwebu: Eduze kwendawo, amabhamuza akhuphukayo asiza ukuhlukanisa ungqimba oluminyene lwegwebu olungavimbela ukuxoshwa kwegesi.

Imiphumela Engaba Mibi Engenzeka (Idinga Ukulawulwa)

Ukwethulwa kwamabhamuza amasha: Uma amapharamitha okubhamuza (ingcindezi yegesi, imvamisa, kanye nobumsulwa) kulawulwa ngendlela engafanele noma uma imibhobho ivinjiwe, inqubo ingasethula amabhamuza amasha angafuneki, amancane. Uma lawa mabhamuza engakwazi ukususwa noma ancibilikiswe ekuhlawulisweni okulandelayo, aba amaphutha.

Ukukhetha Okungalungile Kwegesi: Uma igesi ejovwe isabela ngendlela engafanele ngengilazi encibilikisiwe noma amagesi ancibilikisiwe, ingakhiqiza amagesi noma izinhlanganisela okunzima kakhulu ukuwakhipha, okuvimbela inqubo yokuhlawuliswa.

3. Umthelela Wokubhubhudla Enqubweni Ye-Homogenization (Okuhle Ngokuyinhloko)

Ukugwedla kuthuthukisa kakhulu ukuxubana kanye homogenization of theingilazi encibilikisiwe.

I-Convection Ethuthukisiwe kanye Nokuyaluza

Ukujikeleza Okuqondile: Njengoba amakholomu ebhamuza ephakama, ukuminyana kwawo okuphansi uma kuqhathaniswa nengilazi encibilikisiwe kudala ukugeleza okuqinile okuya phezulu. Ukuze ugcwalise ingilazi ekhuphukayo, ingilazi ezungezile nephansi igeleza iqonde kukholamu yebhamuza, idale amandla anamandla.ukujikeleza okuqondilenomai-convection. Le convection ephoqelelwe isheshisa kakhulu ukuhlangana okuvundlile kwengilazi encibilikisiwe.

Shear Mixing: Umehluko wesivinini phakathi kwamabhamuza akhuphukayo kanye nengilazi encibilikisiwe ezungezile udala amandla okugunda, okugqugquzela ukuxutshwa kokusabalalisa phakathi kwezingqimba zengilazi eziseduze.

Ukuvuselela Isixhumi esibonakalayo: Ukuyaluza okuvela kumabhamuza akhuphukayo ngokuqhubekayo kuvuselela ukuxhumana phakathi kwengilazi yezingoma ezihlukene, okuthuthukisa ukusebenza kahle kokusatshalaliswa kwamangqamuzana.

Ukuphazanyiswa Kwe-stratification kanye ne-Striations

I-convection enamandla iphuka ngokuphumelelayoukuhlukaniswa kwamakhemikhali noma okushisayofuthiimigqaokubangelwa umehluko wokuminyana, ukukhuphuka kwezinga lokushisa, noma ukuphakela ngendlela engalingani. Ihlanganisa lezi zendlalelo ekugelezeni okuyinhloko kokuxuba.

Lokhu kuyasiza ikakhulukazi ekuqedeni"izindawo ezifile"ezansi ethangini, kunciphisa ukucwebezela kwekristalu noma ukungakwazi ukuhlangana okunamandla okubangelwa ukuma isikhathi eside.

Ukusebenza Kwe-Homogenization Okuthuthukisiwe

Uma kuqhathaniswa ne-convection yemvelo noma ukugeleza kwe-temperature-gradient, i-convection ephoqelelwe ekhiqizwa ukubhubhuza ine-ukuphakama kwamandla aphezulu kanye nokufinyelela okubanzi. Lokhu kusifinyeza kakhulu isikhathi esidingekayo ukuze kuzuzwe izinga elifiswayo le-homogeneity noma ukuzuza ukufana okuphezulu phakathi nesikhathi esifanayo.

Imiphumela Engaba Mibi Engenzeka (Idinga Ukunakwa)

Ukuguguleka Kwezinto Eziphikisayo: Ukugeleza kwesivinini esikhulu samabhamuza akhuphukayo kanye nokuguquguquka okunamandla akudalayo kungabangela ukuguguleka okunamandla nokugqwala kwephansi lethangi nezinto ezivimba udonga oluseceleni, kunciphise ukuphila kwesithando somlilo. Lokhu kungase futhi kwethule imikhiqizo yokuguguleka engilazini encibilikisiwe, idale imithombo emisha ye-inhomogeneity (amatshe, imigqa).

Ukuphazanyiswa kwamaphethini okugeleza: Uma isakhiwo sephoyinti elibhamulayo, usayizi webhamuza, noma imvamisa yakhelwe kabi, ingaphazamisa izinga lokushisa langempela, elinenzuzo nezinkambu zokugeleza zemvelo ngaphakathi kwethangi elincibilikayo. Lokhu kungadala izifunda ezintsha ezingajwayelekile noma ama-vortices.

4. Imingcele Yokulawula Okubalulekile ye-Bubbling Technology

Isimo sokubhubhudla: Ngokuvamile engxenyeni yokugcina yendawo encibilikayo (ukuqinisekisa ukuthi izinto ezingavuthiwe zincibilika kakhulu) kanye nendawo yokuncibilika. Isikhundla kufanele sikhethwe ukuze kuthuthukiswe izinkambu zokugeleza nezinga lokushisa.

Ukukhetha Igesi: Izinketho zihlanganisa umoya (izindleko eziphansi, kodwa izakhiwo eziqinile ze-oxidizing), i-nitrogen (inert), namagesi angenayo njenge-argon (ukungena kahle kakhulu, kodwa kuyabiza). Ukukhetha kuncike ekubunjweni kwengilazi, isimo se-redox, nezindleko.

Usayizi Webhamuza: Okuhle ukukhiqiza amabhamuza amakhulu (amamilimitha amaningana kuya kumasentimitha ububanzi). Amabhamuza amancane akhuphuka kancane, abe nomthelela obuthakathaka wokumunca, futhi angase angakhiphi kalula, abe amaphutha. Usayizi webhamuza ulawulwa idizayini ye-nozzle kanye nomfutho wegesi.

Imvamisa yokubhubhuza: Ukubhavuza ngezikhathi ezithile (isb, kanye njalo emizuzwini embalwa) kuvame ukusebenza kangcono kunokubhavuza okuqhubekayo. Idala ukuphazamiseka okunamandla ngenkathi ivumela isikhathi sokuthi amabhamuza akhishwe kanye nengilazi ukuthi izinze. Ukuqina (izinga lokugeleza kwegesi nokucindezela) kufanele kuhambisane nokujula kwengilazi kanye ne-viscosity.

I-Bubbling Point Isakhiwo: Ukuhlela imigqa eminingi ngephethini ehlukanisiwe evala bonke ububanzi bethangi kuqinisekisa ukuthi ukuhanjiswa kufinyelela kuwo wonke amakhona, kuvimbele "izindawo ezifile." Isikhala sidinga ukuthuthukiswa.

Ukuhlanzeka kwegesi: Ukungcola okunjengomswakama noma amanye amagesi kufanele kugwenywe ukuze kuvinjelwe izinkinga ezintsha.

Sengiphetha, ukugwedla kuwubuchwepheshe obubalulekile obufaka igesi engilazini encibilikisiwe ukudala ukujikeleza okuqinile okuqondile kanye nokuyaluza. Lokhu akusheshisi kakhulu kuphela inqubo yangaphakathi yokuhlawuliswa, kusiza amabhamuza amancane namakhulu ukuthi ahlangane futhi axoshwe, kodwa futhi ahlephule ngokuphumelelayo izendlalelo ezingenayo amakhemikhali nezokushisa futhi aqede ukugeleza kwezindawo ezifile. Ngenxa yalokho, kuthuthukisa kakhulu ukusebenza kahle kwe-homogenization kanye nekhwalithi yengilazi. Kodwa-ke, ukulawula okuqinile phezu kwamapharamitha angukhiye njengokukhethwa kwegesi, indawo, imvamisa, nosayizi wamabhamuza kubalulekile ukuze ugweme ukwethula ukukhubazeka okusha kwamabhamuza, ukuguguleka okubambekayo okubi kakhulu, noma ukuphazamisa indawo yokugeleza yasekuqaleni. Ngakho-ke, nakuba kunezithiyo ezingase zibe khona, i-bubbling iwubuchwepheshe obuyinhloko obungathuthukiswa ukuze kuthuthukiswe kakhulu ukwenziwa kwengilazi.
