Random packing yog ib qho ntawm 3 cov khoom siv tseem ceeb uas siv rau hauv huab hwm coj thiab kev siv cua sov. (Lwm 2 cov khoom siv yog cov txheej txheem ntim khoom thiab cov tais.) Zoo li lwm yam 2 cov khoom siv, lub hom phiaj tseem ceeb ntawm kev ntim khoom yog tsim kom muaj qhov chaw rau vapor / kua sib cuag kom Niam Xwm (thiab Leej Txiv Thermodynamics) tuaj yeem tsim cov tshuaj sib cais. Kev cais tshuaj muaj xws li distillation, nqus thiab stripping.
Random Packing Applied nyob rau hauv cov txheej txheem cog li cas?
Hauv kev sib cais tshuaj lom neeg feem ntau (aka huab hwm coj hloov pauv) cov txheej txheem, vapor yog tsav mus rau hauv kem los ntawm cov cua sov thiab siab thaum cov kua dej poob rau hauv qab lub zog ntawm lub ntiajteb txawj nqus. Muaj 3 lub hauv paus tseem ceeb hauv kev xaiv cov khoom ntim khoom (lossis lwm yam khoom siv loj) thiab lawv muaj peev xwm / siab poob, kev ua haujlwm thiab cov nqi. Qhov loj dua qhov random packing, lub peev xwm ntau dua, tab sis ntawm tus nqi qis dua. Qhov me me ntawm cov ntim khoom, qhov ua tau zoo dua tab sis ntawm tus nqi qis dua thiab tus nqi siab dua. Tus kws tsim qauv tsim yuav tsum xaiv cov khoom ntim uas tsim nyog uas muab kev sib npaug ntawm kev lag luam thiab kev ua haujlwm zoo tshaj plaws.
Raschig Nplhaib Packing- Lub cim thib ib ntawm kev ntim khoom tsis sib xws yog qhov muaj qhov siab tib yam li nws txoj kab uas hla. Txij li thaum Raschig Ring Packing muaj peev xwm tsawg, kev ua haujlwm qis thiab cov nqi siab (hauv cov hlau), nws cov ntawv thov feem ntau txwv rau cov ntawv siv corrosive qhov twg cov khoom siv yog ceramic lossis carbon / graphite. Thaum tsim cov hlau, cov khoom yuav tsum tuab dua vim Raschig Ring tsis muaj kev txhawb nqa sab hauv xws li "ntiv tes" hauv Pall Ring Packing.
Pall Ring Ntim- Xav txog Pall Ring Packing li Raschig Rings nrog lub qhov rais thiab / lossis ntiv tes. Txoj kev loj hlob ntawm Pall Rings yog ib qho kev nce qib loj hauv kev ntim khoom. Los ntawm kev xuas nrig ntaus hauv phab ntsa ntawm lub nplhaib, nws tsim cov ntsiab lus drip nrog lub peev xwm thiab kev ua tau zoo los ntawm 50 feem pua rau 80 feem pua ntawm Raschig Ring Packing. Zoo li Raschig Ring Packing, Pall Rings yog tus cwj pwm los ntawm qhov siab tib yam li nws txoj kab uas hla. Pall Rings feem ntau siv rau hauv cov kev pabcuam nqus thiab distillation.
High Performance Saddle-Ring- Saddle Ring Packing tuaj yeem hloov Pall Rings kom xa cov txiaj ntsig zoo dua thiab muaj peev xwm hauv tib lub txaj qhov siab thiab txoj kab uas hla. Qhov thib 3 tiam ntawm random packing tau tsim nrog lub hom phiaj los tsim kom muaj qhov sib piv qis packing; piv txwv li muaj qhov siab tsawg dua qhov nominal txoj kab uas hla ntawm lub ntim. Qhov qis nam piv packing txhawb kev txhim kho kom zoo ntawm lub txaj packed vim Saddle Nplhaib nyob rau hauv ib txoj kev uas orients ntau tiaj tiaj tiaj thaum uas tig mus vapor thiab kua khiav. Qhov tshwm sim yog muaj peev xwm nce ntxiv thaum tuav thaj chaw zoo rau vapor / kua sib cuag. Cov "rings" no xa cov peev txheej thiab kev ua haujlwm ntau dua li Pall Ring packing. Cov ntawv thov suav nrog kev siv nyob rau hauv atmospheric thiab high-pressure distillation, dej qaub stripping, demethanizers, deethanizers, acid gas tshem tawm, quench towers, thiab lub ntsiab fractionators.
