nkhani

Kubowoleza, njira yovuta komanso yogwiritsidwa ntchito kwambiri pakukakamiza homogenization, kwambiri komanso movutikira kumakhudza ma fining ndi ma homogenization agalasi losungunuka. Pano pali kusanthula mwatsatanetsatane.

1. Mfundo ya Bubbling Technology

Kuwombera kumaphatikizapo kuyika mizere ingapo ya ma bubblers (nozzles) pansi pa ng'anjo yosungunuka (makamaka kumapeto kwa malo osungunuka kapena malo osungunuka). Mpweya wina wake, womwe nthawi zambiri umakhala woponderezedwa, nayitrojeni, kapena gasi wolowera, amabayidwa mugalasi losungunuka lotentha kwambiri nthawi ndi nthawi kapena mosalekeza. Mpweyawo umakula ndikukwera kudzera mu galasi losungunuka, ndikupanga mizere ya thovu lokwera.

2. Zotsatira za Kubowoleza pa Njira Yopangira Malipiro (Kwabwino Kwambiri)

Kubowoleza makamaka kumathandiza kuchotsa thovu gasi, potero kumveketsa galasi.

Kulimbikitsa Kuchotsa Mabubu

Kuyamwa Zotsatira: Malo omwe ali ndi mphamvu yotsika amapangika pambuyo pa kuphulika kwakukulu, komwe kukukwera, kumapanga "kupopera mphamvu." Izi zimakoka bwino, kusonkhanitsa, ndi kuphatikiza tinthu ting'onoting'ono ting'onoting'ono kuchokera pagalasi losungunuka, kuwatengera pamwamba kuti awatulutse.

Kuchepetsa Kusungunuka kwa Gasi: Mpweya wobayidwa, makamaka mpweya wa inert, ukhoza kusungunula mpweya wosungunuka mu galasi losungunuka (mwachitsanzo, SO₂, O₂, CO₂), kuchepetsa kupanikizika kwawo pang'ono. Izi facilitates exsolution wa kusungunuka mpweya mu kukwera thovu.

Kuchepetsedwa Kwa Supersaturation Yamaloko: The kukwera thovu kupereka okonzeka zopangidwa gasi-zamadzimadzi mawonekedwe, kupangitsa kukhala kosavuta kuti supersaturated kusungunuka mpweya kusungunuka ndi kufalikira mu thovu.

Njira Yofupikitsa Yomaliza: Mizati yokwera yomwe ikukwera imakhala ngati "njira zothamanga," zomwe zimafulumizitsa kusamuka kwa mpweya wosungunuka ndi tinthu tating'onoting'ono tomwe timayang'ana pamwamba.

Kusokonezeka kwa Chithovu: Pafupi ndi pamwamba, thovu lokwera limathandizira kuswa chithovu chowundana chomwe chingalepheretse kutuluka kwa gasi.

Zomwe Zingachitike Zoyipa (Zikufunika Kuwongolera)

Kuyambitsa New Bubbles: Ngati kuphulika kwa magawo (kuthamanga kwa gasi, mafupipafupi, ndi chiyero) sikuyendetsedwa bwino kapena ngati ma nozzles atsekedwa, ndondomekoyi ikhoza kuyambitsa thovu losafunikira, laling'ono. Ngati thovuli silingachotsedwe kapena kusungunuka mumalipiro otsatila, amakhala ndi zilema.

Kusankha Gasi Molakwika: Ngati mpweya wobayidwayo uchita molakwika ndi galasi losungunuka kapena mpweya wosungunuka, ukhoza kutulutsa mpweya wovuta kwambiri kuchotsa kapena mankhwala, zomwe zimalepheretsa kupukuta.

3. Kukhudzidwa kwa Kubowoleza pa Homogenization Process (Positive)

Kubowoleza kwambiri kumawonjezera kusanganikirana ndi homogenization wagalasi losungunuka.

Kuwonjezeka kwa Convection ndi Agitation

Kuzungulira Kwambiri: Pamene mizati ya buluu ikukwera, kachulukidwe kake kakang'ono poyerekeza ndi galasi losungunuka kumapangitsa kutuluka kwamphamvu m'mwamba. Kuti muwonjezere galasi lokwera, galasi lozungulira ndi lapansi limayenda mozungulira molunjika kugawo la thovulo, ndikupanga mphamvu yamphamvu.kuzungulira kolunjikakapenaconvection. Kusuntha kokakamiza kumeneku kumafulumizitsa kwambiri kusakanikirana kopingasa kwa galasi losungunuka.

Kumeta ubweya Kusakaniza: Kusiyanasiyana kwa liwiro pakati pa magalasi okwera ndi magalasi osungunuka ozungulira kumapangitsa kukameta ubweya, kulimbikitsa kusakanikirana kosakanikirana pakati pa zigawo zoyandikana za galasi.

Kusintha kwa Chiyankhulo: Kusokonekera kwa thovu lokwera limatsitsimula mosalekeza kulumikizana pakati pa magalasi amitundu yosiyanasiyana, kumapangitsa kuti ma cell afalikire bwino.

Kusokonezeka kwa Stratification ndi Striations

Convection yamphamvu imasweka bwinomankhwala kapena kutentha stratificationndimaulendochifukwa cha kusiyana kwa kachulukidwe, kutentha kwa kutentha, kapena kudyetsa kosagwirizana. Zimaphatikizapo zigawozi mumayendedwe akuluakulu osakanikirana.

Izi ndizothandiza makamaka pakuchotsa"Dead zones"pansi pa thanki, kuchepetsa crystallization kapena inhomogeneity kwambiri chifukwa cha Kusayenda kwa nthawi yaitali.

Kuchita bwino kwa Homogenization

Poyerekeza ndi ma convection achilengedwe kapena mafunde a kutentha-gradient, kusuntha kokakamiza kopangidwa ndi kuwira kumakhala ndikuchulukirachulukira kwamphamvu komanso kufalikira kwamphamvu. Izi zimafupikitsa kwambiri nthawi yofunikira kuti mukwaniritse mulingo wofunikira wa homogeneity kapena kukwaniritsa kufanana kwakukulu mkati mwa nthawi yomweyo.

Zovuta Zomwe Zingachitike (Ndimafunika Chidwi)

Refractory Material kukokoloka: Kuthamanga kwambiri kwa thovu lokwera kwambiri komanso kugwedezeka kwakukulu komwe kumapangitsa kungayambitse kukokoloka kwamphamvu ndi dzimbiri la pansi pa thanki ndi zinthu zomangira m'mbali mwa khoma, kufupikitsa moyo wa ng'anjo. Izi zitha kuyambitsa kukokoloka kwa magalasi osungunuka, ndikupanga magwero atsopano a inhomogeneity (miyala, mizere).

Kusokonezeka kwa Njira Zoyenda: Ngati masanjidwe a malo opumira, kukula kwa kuwira, kapena ma frequency sanapangidwe bwino, amatha kusokoneza kutentha koyambirira, kopindulitsa komanso malo oyenda achilengedwe mkati mwa thanki yosungunuka. Izi zitha kupanga madera atsopano osasinthika kapena ma vortices.

4. Zofunika Kulamulira Magawo a Bubbling Technology

Malo Obwebweta: Nthawi zambiri kumapeto kwa malo osungunuka (kuwonetsetsa kuti zinthu zopangira zimasungunuka kwambiri) komanso chigawo chowongolera. Malowa ayenera kusankhidwa kuti akwaniritse bwino mayendedwe ndi kutentha.

Kusankha Gasi: Zosankha zikuphatikizapo mpweya (wotsika mtengo, koma wamphamvu oxidizing katundu), nayitrogeni (inert), ndi mpweya inert monga argon (bwino inertness, koma mtengo). Kusankha kumatengera kapangidwe ka galasi, mawonekedwe a redox, ndi mtengo wake.

Kukula kwa Bubble: Choyenera ndikutulutsa thovu lalikulu (mamilimita angapo mpaka masentimita awiri). Ma thovu ang'onoang'ono amawuka pang'onopang'ono, amakhala ndi mphamvu yoyamwa yofooka, ndipo sangatulutsidwe mosavuta, kukhala zilema. Kukula kwa bubble kumayendetsedwa ndi kapangidwe ka nozzle ndi kuthamanga kwa gasi.

Kubwebweta pafupipafupi: Kubwebweta kwanthawi ndi nthawi (monga kamodzi mphindi zingapo zilizonse) kumakhala kothandiza kuposa kungobwebweta mosalekeza. Zimapanga zosokoneza zamphamvu pamene zimalola nthawi yotulutsa thovu ndi galasi kuti likhale lokhazikika. Kuchuluka (kuthamanga kwa gasi ndi kuthamanga) kuyenera kufanana ndi kuya kwa galasi ndi kukhuthala.

Bubbling Point Layout: Kukonza mizere ingapo motsatizana yomwe imakwirira m'lifupi mwake mwa thanki kumawonetsetsa kuti ma convection afika pamakona onse, kuteteza "madera akufa." Kutalikirana kuyenera kukonzedwa bwino.

Gasi Purity: Zonyansa monga chinyezi kapena mpweya wina ziyenera kupewedwa kuti tipewe mavuto atsopano.

Pomaliza, kuphulika ndi ukadaulo wofunikira kwambiri womwe umalowetsa gasi mugalasi losungunuka kuti liziyenda molunjika komanso kugwedezeka. Izi osati kwambiri Iyamba Kuthamanga mkati fining ndondomeko, kuthandiza thovu ang'onoang'ono ndi lalikulu kuphatikiza ndi kuthamangitsidwa, komanso mogwira amaswa mankhwala ndi matenthedwe inhomogeneous zigawo ndi kuthetsa otaya madera akufa. Choncho, izo kwambiri bwino homogenization dzuwa ndi khalidwe la galasi. Komabe, kuwongolera mosamalitsa magawo ofunikira monga kusankha gasi, malo, ma frequency, ndi kukula kwa kuwira ndikofunikira kuti tipewe kuyambitsa zolakwika zatsopano za kuwira, kukulitsa kukokoloka koyipa, kapena kusokoneza gawo loyambira. Chifukwa chake, ngakhale ili ndi zovuta zina, kuphulika ndiukadaulo wofunikira womwe ungathe kukonzedwa kuti upititse patsogolo kupanga magalasi.
