1. Qhov zoo ntawmmolecular sieve
Precise xaiv adsorption:
Molecular sieve tuaj yeem xaiv adsorb dej molecules yam tsis muaj kev cuam tshuam rau lub neej ntawm acetone molecules.
High adsorption muaj peev xwm:
Molecular sieve muaj peev xwm adsorption siab heev thiab tuaj yeem ua tiav cov dej tshem tawm hauv lub sijhawm luv luv. Tom qab lub molecular sieve tau ua kom tiav, nws cov dej adsorption muaj peev xwm siab dua li lwm cov khoom siv adsorption, thiab cov tshuaj acetone hnyav tuaj yeem ncav cuag ppm qib ntawm cov dej ntsiab lus.
Lub neej ua haujlwm ntev:
Tom qab molecular sieve yog saturated nrog adsorption, nws tuaj yeem rov tsim dua los ntawm lwm txoj kev. Kev pabcuam lub neej ntawm cov khoom zoo molecular sieve tuaj yeem ncav cuag kaum tawm txhiab teev.
2. qauv xaiv ntawm molecular sieve
Txoj kab uas hla ntawm acetone molecule yog hais txog 0.6 nanometers. Nws raug nquahu kom sivChemxin 4A molecular sieve desiccant, uas muaj kev ua haujlwm zoo tshaj plaws.
3. Kev ceev faj rau kev siv molecular sieve
Pretreatment:
Thaum cov tshuaj acetone ntws los ntawm lub tank molecular sieve kom qhuav, nws yuav tsum tau lim ua ntej kom ntseeg tau tias cov tshuaj tau tshem tawm feem ntau ntawm cov dej, tshem tawm cov teeb meem thiab impurities los tiv thaiv kev cuam tshuam rau kev ziab ntawm molecular sieve.
Tswj kub:
Thaum lub sij hawm ob txoj kev ziab thiab cov txheej txheem rov ua dua tshiab, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau kev tswj xyuas qhov kub thiab txias. Qhov kub thiab txias heev yuav cuam tshuam rau cov nyhuv adsorption, thiab qhov kub tsis txaus yuav txo qhov ua kom muaj zog thiab rov tsim dua tshiab.
Xyuas kom lub sijhawm tiv tauj:
Molecular sieve adsorption thiab ziab yog ib qho kev coj cwj pwm ntawm lub cev. Cov tshuaj acetone ntws los ntawm molecular sieve yuav tsum tau tswj lub sijhawm sib cuag kom tsim nyog kom muaj sijhawm txaus.
4. Regeneration txoj kev ntawm molecular sieve
Tom qab molecular sieve yog saturated nrog adsorption, nws muaj peev xwm adsorption tuaj yeem rov qab los ntawm txoj kev tsim dua tshiab.
Ib txoj kev rov tsim dua tshiab yog qhov kub-kub roj desorption, uas yog, cov roj kub kub yog siv los desorb cov acetone molecules adsorbed ntawm molecular sieve, thiab molecular sieve yog regenerated tib lub sij hawm. Tom qab desorption, desorbed acetone tuaj yeem rov qab los ntawm condensation.
