Kubhubhura, nzira yakakosha uye yakashandiswa zvakanyanya mukumanikidzwa homogenization, zvakanyanya uye zvakaomarara zvinokanganisa mafining uye homogenization maitiro egirazi rakanyungudutswa. Heino ongororo yakadzama.

1. Nheyo yeBubbling Technology

Kubhubhura kunosanganisira kuisa mitsara yakawanda yemabubblers (nozzles) pazasi pechoto chinonyunguduka (kazhinji muchikamu chekupedzisira chenzvimbo yekunyungudika kana nzvimbo yekutsvaira). Gasi chairo, rinowanzo kudzvanywa mweya, nitrogen, kana gasi inert, inobairwa mugirazi rakanyungudutswa rinopisa zvikuru nguva nenguva kana kuti inoenderera. Gasi rinowedzera uye rinokwira kuburikidza negirazi rakanyungudutswa, richigadzira makoramu emabhuru anokwira.

2. Mhedzisiro yeKubhubhura paMaitirwo eFining (Kunyanya Yakanaka)

Kubhubhura kunonyanya kubatsira kubvisa mabubbles egasi, nekudaro kujekesa girazi.

Kukurudzira Kubviswa kweBubble

Suction Effect: Nzvimbo yepasi-kudzvanywa inoumbwa mukumuka kwemabhuru makuru, anokwira, achigadzira "kupomba maitiro." Izvi zvinokwevera mukati, zvinounganidza, uye zvinobatanidza tutubu tudiki kubva mugirazi yakanyungudutswa yakatenderedza, kuatakura kuenda pamusoro kuti adzingwe.

Yakaderedzwa Gasi Solubility: Iro jekiseni gasi, kunyanya inert gasi, rinogona kuderedza magasi akanyungudutswa mugirazi yakanyungudutswa (semuenzaniso, SO₂, O₂, CO₂), kuderedza kudzvinyirira kwavo. Izvi zvinogonesa kunyungudutswa kwemagasi akanyungudika mumabhuru anokwira.

Yakaderedzwa Local Supersaturation: Mabhubhu anokwira anopa gasi-riquid interface yakagadzirira, zvichiita kuti zvive nyore kune supersaturated yakanyungudika magasi kunyungudika uye kupararira mumabhuru.

Yakapfupikiswa Yekuita Nzira: Makoramu ari kusimuka anoita se“nzira dzinokurumidza,” achimhanyisa kutama kwemagasi akanyunguduka uye mabhuru madiki akananga pamusoro.

Foam Layer Kukanganisa: Pedyo nepamusoro, mabhuru anokwira anobatsira kuputsa furo rakakora iro rinogona kutadzisa kudzingwa kwegasi.

Zvinogona Negative Effects (Zvinoda Kudzora)

Kusuma New Bubbles: Kana kubhubhura paramita (gasi kudzvinyirirwa, kuwanda, uye kuchena) zvikadzorwa zvisina kunaka kana kana mhuno yakavharika, maitiro anogona kuunza zvisingadiwe, mabhuru madiki. Kana mabubbles aya asingakwanise kubviswa kana kunyungudutswa mukucheneswa kunotevera, anove akaremara.

Kusarudzwa kweGasi kusina kunaka: Kana gasi rakaiswa jekiseni rikaita zvisina kunaka negirazi rakanyungudutswa kana magasi akanyungudutswa, rinogona kuburitsa mamwe magasi akaomarara kana macompounds, zvichitadzisa kuita fining.

3. Mhedzisiro yeBubbling paHomogenization process (Yakanaka kwazvo)

Kubhubhura kunowedzera zvakanyanya kusanganisa uye homogenization yegirazi rakanyungudutswa.

Enhanced Convection uye Agitation

Vertical Circulation: Sezvo mbiru dzebubble dzichikwira, kudzikira kwadzo kuchienzaniswa negirazi rakanyungudutswa kunogadzira kuyerera kwakasimba kukwira. Kuzadza girazi rinokwira, girazi rakatenderedza uye rezasi rinoyerera rakachinjika richienda kubhavhuro column, richigadzira ine simba.vertical kutendererakanaconvection. Uku kumanikidzwa kutenderedzwa kunomhanyisa zvakanyanya kusanganiswa kwakachinjika kwegirazi rakanyungudutswa.

Shear Mixing: Musiyano wevelocity pakati pemabhubhu ari kusimuka uye girazi rakanyungudutswa rakatenderedza rinogadzira masimba ekugera, zvichikurudzira kusanganisa kusanganisa pakati pemagirazi ari pedyo.

Interface Renewal: Iko kubvongodza kubva kumabhubhu anokwira kunoramba kuchizorodza maratidziro ekubatana pakati pegirazi reakasiyana ekuumbwa, achivandudza kugona kwema molecular diffusion.

Kuvhiringidzwa kweStratification uye Striations

Convection yakasimba inoputsa zvinobudirirakemikari kana kupisa stratificationuyestriationszvinokonzerwa ne density kusiyana, tembiricha gradients, kana kudya zvisina kuenzana. Inobatanidza zvidimbu izvi muhuwandu hwekuyerera kwekusanganiswa.

Izvi zvinonyanya kubatsira mukubvisa"nzvimbo dzakafa"pazasi petangi, kuderedza crystallization kana yakanyanya inhomogeneity inokonzerwa nekumira kwenguva refu.

Kuvandudza Homogenization Kubudirira

Kuenzaniswa neakasikwa convection kana tembiricha-gradient inoyerera, iyo yekumanikidza convection inogadzirwa nekupupuma ineyakakwirira simba density uye yakafara kusvika. Izvi zvinopfupisa zvakanyanya nguva inodiwa kuti uwane inodiwa nhanho yehomogeneity kana kuwana yakakwira yunifomu mukati menguva imwecheteyo.

Zvinogona Kuipa Mhedzisiro (Inoda Kutariswa)

Refractory Material Erosion: Kuyerera kwepamusoro-soro kwemabhuru anokwira uye kutenderera kwakasimba kwavanoita kunogona kukonzera kukukurwa kwakasimba nekuora kwepasi petangi uye nemativi-madziro emadziro efractory, kupfupisa hupenyu hwechoto. Izvi zvinogona zvakare kuunza zvigadzirwa zvekukukurwa mugirazi yakanyungudutswa, zvichigadzira zvitsva zveinhomogeneity (matombo, striations).

Kuvhiringidzwa kweMafambiro eKuyerera: Kana iyo inobhubhura nzvimbo, saizi yebubble, kana frequency isina kugadzirwa zvakanaka, inogona kukanganisa yekutanga, inobatsira tembiricha uye minda yekuyerera yakasikwa mukati metangi inonyungudika. Izvi zvinogona kugadzira matunhu matsva asina kukwana kana mavhu.

4. Key Control Parameters yeBubbling Technology

Kubhubhura Position: Kazhinji muchikamu chekupedzisira chenzvimbo yekunyunguduka (kuve nechokwadi chekuti zvigadzirwa zvakanyungudika zvakanyanya) uye nzvimbo yekuchenesa. Nzvimbo yacho inofanirwa kusarudzwa kuti iwedzere kuyerera uye tembiricha minda.

Kusarudzwa kweGasi: Sarudzo dzinosanganisira mhepo (yakaderera mutengo, asi yakasimba oxidizing zvivakwa), nitrogen (inert), uye inert magasi senge argon (yakanakisa inertness, asi inodhura). Sarudzo inoenderana nekuumbwa kwegirazi, redox mamiriro, uye mutengo.

Kukura kweBubble: Yakanakira kugadzira mabhuru akakura (mamirimita akati wandei kusvika masendimita mudhayamita). Mabhuru madiki anosimuka zvishoma nezvishoma, ane simba rekusveta zvisina simba, uye anogona kusadzingwa zviri nyore, achive hurema. Saizi yeBubble inodzorwa nenozzle dhizaini uye gasi kudzvanywa.

Kuputika Frequency: Kubhuroka nguva nenguva (semuenzaniso, kamwe pamaminetsi mashoma ega ega) kunowanzo shanda pane kungoramba uchitubwida. Inogadzira kukanganisa kwakasimba ichibvumira nguva yekuti mabhubhu adzingwe uye girazi rigadzikane. Kusimba (kuyerera kwegasi uye kudzvanywa) kunofanirwa kufananidzwa nekudzika kwegirazi uye viscosity.

Bubbling Point Layout: Kuronga mitsara yakawanda mune yakadzama pateni inovhara hupamhi hwese tangi inoita kuti convection isvike pamakona ese, kudzivirira "nzvimbo dzakafa." Iyo spacing inoda kuvandudzwa.

Gasi Purity: Tsvina yakaita semwando kana mamwe magasi inofanira kudzivirirwa kudzivirira matambudziko matsva.

Mukupedzisa, kubhuroka ndiyo yakakosha tekinoroji inopinza gasi mugirazi rakanyungudutswa kugadzira kutenderera kwakasimba kwakamira uye kubvongodza. Izvi hazvingoiti zvakanyanya kukurumidza kuita mukati mefining process, zvichibatsira mabhuru madiki nemahombe kubatana uye kudzingwa, asiwo zvinobudirira kuputsa kemikari uye inopisa inhomogeneous layers uye inobvisa kuyerera kwakafa nzvimbo. Nekuda kweizvozvo, inovandudza zvakanyanya kugona kwehomogenization uye kunaka kwegirazi. Nekudaro, kudzora kwakasimba pamusoro peakakosha paramita senge gasi kusarudzwa, chinzvimbo, frequency, uye bubble saizi kwakakosha kudzivirira kuunza hutsva hurema hwebubble, kuwedzera kuderera kwekukukurwa, kana kukanganisa iyo yekutanga kuyerera. Naizvozvo, kunyangwe iine zvimhingamupinyi zvinogoneka, kubhuroka ndiyo yakakosha tekinoroji inogona kuvandudzwa kuti iwedzere zvakanyanya kugadzira girazi.
