Isisefo samangqamuzana, ngenxa yomthamo waso oqinile wokukhangisa nokumelana nezinga lokushisa eliphezulu, sisetshenziswa kabanzi emabhizinisini amaningi ezimboni.Amasefa amamolekyuli asetshenziswa kakhulu akhiqizwa yiJXKELLEYkukhona 3A, 4A, 5A, 13X nezinye izinhlobo zezisefo zamangqamuzana.Ngakho-ke ungayinweba kanjani impilo yesevisi ye-molecular sieve ngokusebenzisa amasu ama-2?
1. Sebenzisa indawo ezungezile
1. Indawo esetshenziswayo ye-sieve yamangqamuzana ihlobene nomswakama wayo wemvelo, ingcindezi yesilingo, ukuminyana kokugcwalisa, njll. Ingasetshenziswa iminyaka engu-2-3 ngaphansi kwezimo ezivamile.Uma indawo yokugcina izinto iyinhle, futhi ingekho ingozi yokukhiqiza, isikhathi sayo sokuphila singasetshenziswa iminyaka engaphezu kwemi-5.
2. Izisefo ezintsha zamangqamuzana, ngaphandle uma kuboniswe ngokucacile ukuthi zenziwe zasebenza futhi zavalwa.Uma kungenjalo, kusadingeka ukuthi kwenziwe kusebenze ukushisa okuphezulu kokubhaka, ngokuvamile ama-degree angu-500 anele.Ukwenza kusebenze kwenziwa esithandweni se-muffle.Kungcono ukudlulisa umoya we-cylinder noma i-nitrogen esithandweni, bese upholisa ngokwemvelo kuze kufike kuma-degrees angaba ngu-100 ngaphansi kwezimo zomoya, uwukhiphe bese uwudlulisela ku-desiccator ukuze ugcine umoya.
2. Isetshenziswa kanjani
1. Ukusetshenziswa kahle kwesisefo samangqamuzana.Ngesikhathi sokusebenza, kufanele sisebenze ngokuhambisana ngokuqinile nenani lokuklama lempahla ye-adsorption, futhi silandele ngokuqinile izinkomba ezibalulekile njengezinga lokugeleza, izinga lokushisa, ingcindezi, isikhathi sokushintsha sokuphakelayo esisethwe uhlelo.Inani elimisiwe alikwazi ukushintshwa ngokuzenzakalelayo.Umshini wokukhangisa we-molecular sieve enomklamo ozwakalayo kanye nokusetshenziswa okufanele kufanele usetshenziselwe amahora angu-24'000-40'000, okungaba iminyaka emi-3 kuya kwemi-5.
2. Isisefo samangqamuzana esisezingeni eliphezulu singanciphisa kakhulu okuqukethwe kwamanzi emoyeni, sivimbele ukungcoliswa kwamafutha okugcoba, ukushisa okulungile nokuvuselelwa kabusha, futhi kususe impushana ngesikhathi.Ngaphezu kwalokho, enqubweni yokuvuselela isihlungo samangqamuzana, kungcono kakhulu ukusebenzisa igesi eyomile yomkhiqizo ephathwa ngesihlungo samangqamuzana noma igesi ephansi yamazolo yezinye izinqubo, futhi akufanelekile ukusebenzisa umoya wegumbi lokushisa ukuze uvuselele umbhede we-molecular sieve.
3. Esigabeni sokupholisa, qaphela ukusebenza okufanele.Ukushisa kwinqubo yokuvuselela kufanele kwenziwe kancane kancane ngezigaba futhi akukwazi ukushiswa ngokuqondile ku-200-300 degrees.Umbhede we-sieve ye-molecular evuselelwe ibuyele emuva ngokuqondile, futhi igesi yokuvuselela kufanele ihlale cishe ngama-degree angu-150 lapho ishisa.Isikhathi sokushisa nokuvuselelwa kabusha siyiphuzu elibalulekile okufanele linakwe.
Indlela yokwahlulela ukuthi i-sieve yamangqamuzana efektri idinga ukushintshwa?Ngokuvamile, singabheka ukuthi siphelelwe yisikhathi ngokwemiyalo yokusetshenziswa.Uma iphelelwa yisikhathi, idinga ukushintshwa.Uma isisefo se-molecular singene emanzini, sidinga ukushintshwa nganoma yisiphi isikhathi.Ngemuva kokucwiliswa kwamanzi, ngisho noma kusetshenziswa ukuvuselelwa okukhethekile, isihlungi se-molecular sizoba ngaphansi komthelela wokugeleza komoya.Ukuholela ekulimazeni, ukuvinjwa kalula isishintshi sokushisa, futhi ukunakekelwa okulandelayo kuba nzima kakhulu.Ngesikhathi esifanayo, kuncike ekutheni umswakama kanye ne-carbon dioxide okuqukethwe kwegesi ehlanzekile kungaphakathi kwenkomba.Uma idlula inkomba, idinga ukushintshwa ngokushesha.Kuphela ngokukhetha indawo enhle yokusebenza, kanye nokugcinwa nokugcinwa, impilo yayo yesevisi inganwetshwa ngokuphumelelayo.
