2 lub tswv yim kom ncua lub neej ntawm molecular sieves

Molecular sieve, vim nws muaj zog adsorption muaj peev xwm thiab kub tsis kam, yog dav siv nyob rau hauv ntau lub lag luam.Feem ntau siv molecular sieves tsim los ntawmJXKELLEYyog 3A, 4A, 5A, 13X thiab lwm hom molecular sieves.Yog li yuav ua li cas txuas ntxiv lub neej kev pabcuam ntawm molecular sieve los ntawm 2 cov txheej txheem?
1. Siv ib puag ncig
1. Kev siv ib puag ncig ntawm molecular sieve muaj feem xyuam rau nws cov av noo ib puag ncig, kev sim siab, filling ceev, thiab lwm yam. Nws tuaj yeem siv rau 2-3 xyoos raws li qhov xwm txheej ib txwm muaj.Yog tias qhov chaw cia khoom zoo, thiab tsis muaj kev sib tsoo ntau lawm, nws lub neej yuav siv tau ntau dua 5 xyoos.
2. Tshiab molecular sieves, tshwj tsis yog nws tau qhia meej tias lawv tau qhib thiab kaw.Tsis tas li ntawd, nws tseem yuav tsum tau qhib los ntawm kev kub siab ci, feem ntau 500 degrees txaus.Kev ua kom ua haujlwm yog nqa tawm hauv lub qhov cub muffle.Nws yog qhov zoo dua los hla lub tog raj kheej cua lossis nitrogen rau hauv lub qhov cub, thiab tom qab ntawd txias txias txog li 100 degrees hauv qhov cua, tshem nws tawm thiab hloov mus rau lub desiccator rau airtight cia.
2. Yuav siv li cas
1. Kev siv cov molecular sieve kom raug.Thaum lub sijhawm ua haujlwm, peb yuav tsum ua haujlwm nruj raws li tus qauv tsim tus nqi ntawm cov khoom siv adsorption, thiab nruj me ntsis ua raws li cov ntsuas tseem ceeb xws li tus nqi ntws, kub, siab, hloov sijhawm ntawm cov khoom noj los ntawm lub kaw lus.Cov nqi teeb tsa tsis tuaj yeem hloov pauv tau arbitrarily.Cov khoom siv molecular sieve adsorption nrog tsim tsim nyog thiab siv tau zoo yuav tsum tau siv rau 24'000-40'000 teev, uas yog kwv yees li 3 mus rau 5 xyoos.

2. Cov khoom zoo molecular sieve tuaj yeem txo cov dej hauv cov huab cua zoo heev, tiv thaiv kom tsis txhob muaj kuab paug ntawm cov roj lubricating, kho cua sov thiab rov tsim dua tshiab, thiab tshem tawm cov hmoov hauv lub sijhawm.Tsis tas li ntawd, nyob rau hauv cov txheej txheem molecular sieve regeneration, nws yog qhov zoo tshaj plaws los siv cov khoom qhuav roj kho los ntawm molecular sieve los yog qis qis taw tes roj ntawm lwm cov txheej txheem, thiab nws tsis tsim nyog siv cov cua kub hauv chav tsev kom rov tsim cov molecular sieve txaj.
3. Nyob rau hauv lub caij txias, xyuam xim rau kev ua haujlwm kom raug.Cov cua sov hauv cov txheej txheem rov tsim dua yuav tsum tau ua qeeb qeeb hauv theem thiab tsis tuaj yeem ncaj qha rhuab mus rau 200-300 degrees.Lub txaj ntawm regenerated molecular sieve yog ncaj qha rov qab, thiab cov roj regeneration yuav tsum nyob ntawm li 150 degrees thaum cua sov.Lub sijhawm cua sov thiab rov tsim dua tshiab kuj yog ib qho tseem ceeb uas yuav tsum tau saib xyuas.

Yuav ua li cas txiav txim siab tias molecular sieve nyob rau hauv lub Hoobkas yuav tsum tau hloov?Feem ntau, peb tuaj yeem tshawb xyuas seb nws puas tau tas sijhawm raws li cov lus qhia rau kev siv.Yog tias nws tas sij hawm, nws yuav tsum tau hloov.Yog tias molecular sieve tau nkag mus rau hauv dej, nws yuav tsum tau hloov txhua lub sijhawm.Tom qab dej raus dej, txawm tias siv tshwj xeeb rov tsim dua tshiab, cov molecular sieve yuav raug cuam tshuam los ntawm airflow.Ua rau tawg, yooj yim los thaiv cov cua kub exchanger, thiab kev txij nkawm tom qab yog teeb meem ntau dua.Nyob rau tib lub sijhawm, nws nyob ntawm seb cov dej noo thiab carbon dioxide cov ntsiab lus ntawm cov pa purified yog nyob rau hauv qhov ntsuas.Yog tias nws tshaj qhov ntsuas, nws yuav tsum tau hloov tam sim ntawd.Tsuas yog los ntawm kev xaiv ib puag ncig kev ua haujlwm zoo, nrog rau kev khaws cia thiab kev saib xyuas, tuaj yeem ua rau nws lub neej ua haujlwm tau zoo.
