Nzira yekuvandudza sei 4a molecular sieve mushure mekutora unyoro

Kana 4a molecular sieve isina kurongedzerwa zvakasimba kana nzvimbo yekuchengetera yakakuvadzwa, maitiro ekuita nekunyura kwayo kwemvura uye unyoro?Nhasi isu tichatsanangura iyo adsorption kugona kwema molecular sieve uye nzira dzekurapa dzekunyudza mvura uye hygroscopicity.

Molecular sieve ine simba rekushambadza rakasimba.Haigoni kungotora mvura chete, asiwo inotora tsvina mumhepo.Naizvozvo, mukugadzirwa kwemaindasitiri, inowanzoshandiswa kune adsorption mashandiro, nekudaro ichiita basa rakanaka mukuparadzanisa uye adsorption.Chii chatinofanira kuita kana 4a molecular sieve yakachengetwa zvisina kunaka kana kunyoroveswa zvakanyanya panguva yekushandiswa?

1. Vharaiyo main tower inlet valve, ingochinja masieve emamorekuru ematangi maviri ekushambadza, uye shandisa mhepo kuseri kwema molecular sieves pasina mvura kudzorera mamorekuru masefa.Zvisinei, kana masefa emokuru asina mvura achinjwa kuti ashande, mvura iri kuseri kwawo inopinda mumasefa mamorekuru pasina mvura.Aya maviri ma molecular sieves ese ane mvura, obva achinjana.Nekuvandudzwa kwe adsorption, iyo yemvura inodzikira, uye pakupedzisira inowana panguva imwe chete adsorption.

2.Directlykupisa uye kuomesa 4a molecular sieve kuti ibvise mvura nokukurumidza sezvinobvira uye kudzorera simba rayo rekudsorption;Zvisinei, mushure mokunge mvura yakawanda inopinda mumusero we molecular, kana uchishandisa nzira iri pamusoro apa kuti idzokezve, mashefu ose e-molecular achaita mvura yakawanda, ose ari maviri achavandudza uye anozopedzisira arasikirwa nekwanisi yeadsorption.Chikonzero ndechokuti: mushure mokunge mvura yakawanda inopinda mu zeolite, mvura inopindirana ne zeolite, uye mvura inoshanduka kubva kune yakasununguka kusvika kune crystal mvura ye zeolite.Kunyange kana kutonhora kwekuzvarwa patsva kuri madhigirii mazana maviri, mvura yekristaro haigone kubviswa, uye basa rekushambadza rezeolite rinogona kudzoserwa chete mushure mekunge radzoserwa muchoto pa400 degrees nemugadziri!

Nokudaro, apo molecular sieve inotora mvura munzvimbo yakakura uye inobatwa nehunyoro, kushanda kuchamiswa pakarepo uye kuberekwa patsva kuchaitwa.Kana iyo adsorption isingakwanise kudzoserwa nemaitiro maviri ari pamusoro, mugadziri anozobatwa nekukurumidza sezvinobvira kuti agadzirise calcination.

4a Molecular sieve activation uye nzira yekuzvarwa patsva:

1. 4a Shanduko yetembiricha yezeolite, iyo "inoshanduka tembiricha"

Iyo adsorbate inobviswa nekupisa iyo molecular sieve.Kazhinji, masefa emamorekuru anoshandiswa muindasitiri anofanopiswa uye anopiswazve, anocheneswa kusvika pa200 ℃, uye desorbed adsorbate inotorwa kunze.

2. Shandura kumanikidzwa kunoenderana kwe4a zeolite

Ndiko kuti, mukuita kwegasi chikamu adsorption, iyo yakakosha nzira ndeyekuchengetedza tembiricha ye adsorbent nguva dzose, uye kubvisa iyo adsorbate kuburikidza ne decompression uye kumashure kuvhuvhuta kweinert gasi.

Muchirongwa chekuvandudzwa kwe4a molecular sieve, kutarisisa kunofanirwa kubhadharwa kudzivirira kuwanda kwemvura inopinda, kupindirana pakati pemvura uye sieve yemamorekuru, uye kushandurwa kwemvura kubva kune yakasununguka nyika kuenda kune crystalline state.Kunyangwe kana tembiricha yekuvandudza inosvika 200 ℃, zvakaoma kubvisa mvura ine crystalline.Kana nguva yekudya ichipfuura maminitsi e10, uye mavara akajeka emvura anogona kuonekwa mushure mokunge gasi rekuvandudza rave richibuda, zvinogona kutongwa kuti molecular sieve inoda kudzorerwa muchoto pasina kuvandudzwa.
