random packing yog siv nyob rau hauv sib cais kem, xws li distillation kab, kom qhov chaw nto rau vapor/kua sib cuag, ua tshuaj sib cais ntau npaum. Cov khoom me me ntawm random packing nyob rau hauv ib kem distillation yog tsim los tsim ib tug loj cheeb tsam uas reactants tuaj yeem cuam tshuam thaum txo qhov nyuaj nyob rau hauv kem. random packing yog tsim los ua kom lub ntsej muag-rau-ntim piv thiab txo qis kev poob siab.
Qhov kev ua tau zoo ntawm kev ntim khoom nyob ntawm ntau yam-kev ua tau zoo, kev poob siab, thiab lub peev xwm. Feem ntau, thaum random packing loj, muaj peev xwm nce, tab sis efficiency txo. Conversely, thaum random packing me me, efficiency nce, tab sis muaj peev xwm txo. Kev poob siab qis yog qhov xav tau, vim tias kev kub siab poob qis txo kev ua haujlwm thiab kev ua haujlwm.
Keeb kwm, random packing yog ua los ntawm ceramic. Vim hais tias ceramics yog nkig, lawv siv tau ploj mus, tab sis lawv tseem siv nyob rau hauv qee daim ntawv thov uas yuav tsum tau muaj zog corrosion kuj. Niaj hnub no, ntau lub hnab ntim khoom yog tsim los ntawm cov hlau thiab yas, nrog rau ob peb lwm cov ntaub ntawv siv rau kev siv tshwj xeeb.
random packing ua haujlwm li cas?
Thaum random packing yog ntsia, cov khoom yog poured rau hauv kem thiab tso cai rau khom. Cov khoom yog randomly sau nyob rau hauv ib lub txaj ntawm packing nyob rau hauv ib lub nkoj sau. Cov kua yuav tsum tau sib cais ces ntws los ntawm cov khoom.
Random packings tuaj nyob rau hauv ntau yam configurations:
1. Raschig Rings
Raschig nplhaib packings siv me me ntawm tubing los tsim lub txaj packing. Cov raj me me no feem ntau yog ntev npaum li lawv qhov dav. Raschig rings yog cov laus, tsis paub tab cov khoom ntim. Lawv yog cov du thiab tsis muaj qhov, grooves, tav, lossis lwm yam khoom siv. Lawv muaj peev xwm qis dua thiab ua haujlwm tau zoo thiab yuav raug nqi ntau dua li lwm hom random packings. Daim ntawv thov rau hom kev ntim khoom no raug txwv vim tias tus nqi ntawm Raschig rings siab dhau lawm piv rau lawv cov txiaj ntsig. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv ntawm kev sib cais cov ntaub ntawv corrosive, ceramic Raschig rings zoo vim lawv cov corrosion kuj siab.
2. Pall Rings
Pall rings zoo ib yam li Raschig rings, tab sis muaj ntau txoj hauv kev. Pall rings suav nrog cov qauv kev txhawb nqa sab hauv thiab sab nraud. Texturing nyob rau hauv lub nplhaib phab ntsa tso cai rau cov ntsiab lus drip sab hauv, uas ua rau kom muaj peev xwm thiab ua tau zoo ntawm cov ntim khoom. Pall rings yog tshwj xeeb tshaj yog pab tau nyob rau hauv distillation thiab nqus daim ntaub ntawv.
3. Saddle Rings
Muaj ob hom eeb rings - Berl eeb rings thiab Intalox ® eeb rings. Raws li lub npe implies, eeb rings yog zoo li tus me me eeb. Saddle rings txawv ntawm Raschig thiab Pob rings nyob rau hauv uas lawv ntev tshaj li lawv txoj kab uas hla. Smooth Berl eeb rings feem ntau luv dua thiab muaj ib lub eeb dua qub. Intalox ® eeb rings yog ntev dua thiab zoo li zoo li macaroni txiav nyob rau hauv ib nrab lengthwise, tsim ib tug ntev, qhib nkhaus seem. Saddle rings kuj muaj qhov me me thiab grooves uas ua rau thaj tsam ntawm qhov chaw thiab kev sib cuag. Saddle rings muaj thaj tsam ntau dua rau cov kua thiab vapor sib cuag, uas ua rau muaj peev xwm ntau dua thiab ua haujlwm tau zoo. Saddle rings yog zoo tagnrho rau tshuaj distillation, stripping, thiab nqus.
4. Lessing Nplhaib
Lesing Rings yog ua los ntawm ceramic. Lawv muaj cov baffles sab hauv los ua kom thaj chaw saum npoo thiab ua kom muaj zog. Zoo li tag nrho cov khoom ntim ceramic, lawv muaj peev xwm tiv taus cua sov thiab corrosion. Cov khoom no ua rau lawv zoo tagnrho rau kev siv xws li cov txheej txheem oxide regenerative.
5. Tri-Packs
Tri-Packs tau tsim thawj zaug hauv 70s lig thiab tam sim no tau siv dav. Tri-Packs muaj ntau yam zoo dua li cov khoom qub. Vim lawv cov duab kheej kheej, lawv tsis tshua muaj zes thiab nyob. Sab hauv ribs kuj ua kom thaj chaw saum npoo av thiab ntub dej. Rau kev poob qis thiab kev hloov pauv loj heev, Tri-Packs yog qhov kev xaiv zoo. Tri-Packs feem ntau yog tsim los ntawm ntau yam yas uas muaj corrosion thiab kub resistant.
Qhov zoo ntawm Random Packings
Kev sib cais feem ntau yuav tsum tau ntim khoom ntim. Lub ntsiab kom zoo dua ntawm random packings yog tias lawv muaj ntau pheej yig dua los siv dua li cov khoom ntim khoom. Lwm qhov zoo ntawm cov khoom ntim tsis sib xws suav nrog thaj chaw sib txuas ntxiv, kev hloov pauv loj, thiab kev ua haujlwm zoo dua li cov thev naus laus zis qub xws li cov cuab yeej thev naus laus zis, txhua yam tsis muaj tus nqi siab.
Ntxiv nrog rau cov ntawv thov uas tau tham saum toj no, cov ntawv thov rau cov ntim khoom sib txawv xws li stripping, distillation, CO2 scrubbing, thiab kua-kua extraction.
