Ukwethulwa kwemikhiqizo yesisefo ye-molecular 3A eyindilinga
I-3A molecular sieve i-alkali metal aluminosilicate, eyaziwa nangokuthi i-3A zeolite molecular sieve.Isefo ye-molecular yohlobo lwe-3A ibhekisela ku-: Uhlobo lwesisefo se-molecular equkethe i-Na+ ichazwa ngokuthi i-Na-A, uma i-Na+ ithathelwa indawo ngu-K+, usayizi wembobo cishe u-3A we-molecular sieve;3Isisefo samangqamuzana sisetshenziselwa kakhulu ukukhangisa amanzi, futhi ayikhangisi noma iyiphi i-molecule enobubanzi obukhulu kuno-3A, iyadingeka i-Desiccant ekomisweni okujulile, ukucwengwa kanye ne-polymerization yezigaba zegesi neziwuketshezi ezimbonini ze-petroleum nezimboni zamakhemikhali.
Ifomula yamakhemikhali: 2/3K2O·1/3Na2O·Al2O3·2SiO2·9/2H2O
Isilinganiso se-Si-Al: SiO2/Al2O3≈2
Usayizi Wembotshana Osebenzayo: Cishe u-3Å
Izici ze-3A uhlobo lwe-molecular sieve desiccant:
3Isisefo samangqamuzana sinesivinini esisheshayo sokukhangisa, amandla okuchoboza aqinile nekhono lokulwa nokungcola, okwandisa ukusebenza kahle kwesisefo samangqamuzana futhi andise impilo yesevisi yesisefo samangqamuzana.
1. 3Isisefo se-molecular sikhipha amanzi: kuncike ekucindezelweni, izinga lokushisa kanye nokuqukethwe kwamanzi egesi.Igesi yokomisa ku-200～350℃ ingu-0.3～0.5Kg/square centimeter, idlula kumbhede we-molecular sieve amahora angu-3～4, futhi izinga lokushisa eliphumayo lingu-110～180℃ ukuze lipholiswe.
2. 3Ukususwa kwesisefo se-molecular of organic matter: buyisela izinto eziphilayo ngomhwamuko wamanzi, bese ukhipha amanzi.
Ububanzi bokusetshenziswa kwesisefo se-adsorbent 3A molecular:
3Isisefo samangqamuzana sisetshenziswa kakhulu embonini yengilazi yezakhiwo, ukucwenga igesi nokuhlanzwa kanye nemboni ye-petrochemical.
1.3A Ukomiswa kwesisefo se-molecular yoketshezi oluhlukahlukene (njenge-ethanol)
2. Ukomiswa komoya
3. Ukomiswa kwesiqandisi
4.3Ukomiswa kwe-molecular sieve yegesi yemvelo kanye negesi ye-methane
5. Ukomiswa kwama-hydrocarbon angacushiwe kanye negesi eqhekekile, i-ethylene, i-acetylene, i-propylene, i-butadiene, ukomiswa kwegesi eqhekekile ye-petroleum nama-olefin
Izinkomba zobuchwepheshe ze-molecular sieve zohlobo lwe-3A:
izinga lokusetshenziswa: GB/T 10504-2008
Abakhiqizi besisefo samangqamuzana 3A ukupakishwa nokugcinwa kwesisefo samangqamuzana:
3A isisefo samangqamuzana Isitoreji: Ngaphakathi endlini enomswakama ongekho ngaphezu kwamadigri angu-90: gwema amanzi, i-asidi, i-alkali, nomoya ongawodwa ukuze ugcinwe.
I-3A yokupakishwa kwesisefo samangqamuzana: 30Kg idramu yensimbi evaliwe, 150Kg isigubhu sensimbi esivaliwe, isigubhu sensimbi esivaliwe esingu-130Kg (umcu).
incazelo yomkhiqizo:
Usayizi wembotshana we-3A yesisefo semolekyuli ngu-3A.Isetshenziselwa kakhulu ukukhangisa amanzi, futhi ayikhangisi noma yimaphi ama-molecule anobubanzi obukhulu kuno-3A.Ngokwezici zezinhlelo zokusebenza zezimboni, izisefo zamangqamuzana esiwakhiqizayo ngu-Gloria anesivinini esisheshayo sokukhangisa, izikhathi ezengeziwe zokukhiqiza kabusha, eziphakeme Amandla okuchoboza nekhono lokulwa nokungcola kukhulisa ukusebenza kahle kokusetshenziswa kwezisefo zamangqamuzana futhi andise impilo yesevisi yezisefo zamangqamuzana.
Izinyathelo zokuzivikela:
Izisefo zamangqamuzana kufanele zivinjelwe ekukhangiseni amanzi, amagesi emvelo noma uketshezi ngaphambi kokusetshenziswa, ngaphandle kwalokho, kufanele zivuselelwe.
