Mkpịsị mmiri molecular sieve dabere na mmiri dị n'ime ngwaahịa ahụ, ntuziaka iwepụ mmiri molecular sieve 4A.
1. ojiji: 4A molecular sieve nwere ike adsorption nhọrọ ma nwee ike wepụ mmiri mmiri na ihe ndị na-edozi ahụ na gas, ma ọ dịghị adsorb ihe mgbaze na gas (dị ka tetrahydrofuran).Usoro izizi na-anabata akpịrị ịkpọ nkụ soda, caustic soda bụ soluble na mmiri, ọ dịghị mfe ikewapụ na tetrahydrofuran mgbe akpịrị ịkpọ nkụ, na-eji caustic soda na-esi ike maka recycling, abawanyela n'ezie na-eri.
2. Usoro ọrụ: Ọrụ nkụda mmụọ nke sieve molecular 4A dị mfe.Enwere ike itinye sieve molekụla ozugbo na mwepụ ihe mgbaze, ma ọ bụ ihe ngwọta na gas nwere ike gafere ozugbo site na ụlọ elu adsorption molecular sieve.
3. Ike adsorption: Molecular sieve 4A nwere ikike mgbasa ozi buru ibu, n'ozuzu 22%.
4. Nhọrọ nke arụmọrụ adsorption: 4A molecular sieve nwere ike ịmịkọrọ mmiri mmiri ngwa ngwa.N'ihi na dayameta nke ụmụ irighiri mmiri dị ntakịrị karịa nke zeolite, enwere ike nweta nguzozi electrostatic mgbe adsorption gasịrị (nkịta molekụla anaghị amịkọrọ ihe ndị nwere dayameta nke buru ibu karịa nke sieves molecular).
5.Analysis na-enweghị na-emepụta mmiri: 4a molecular sieve agaghị ahapụ mgbe ọ na-amịkọrọ mmiri na ụlọ okpomọkụ.
6. Ntughari: Ntughari nke 4A molecular sieve dị mfe.Mgbe otu awa gachara, enwere ike iji nitrogen dị elu karịa 300 Celsius (ihe anaghị ere ọkụ nwere ike ịgbanye ya n'ikuku ozugbo).
7. Ogologo oge ndụ: 4A molecular sieve nwere ike imegharị maka afọ 3-4.
Sives molecular nwere hygroscopicity siri ike na mmiri, yabụ a ga-eji ya mee ka ọ dị ọcha gas ma zere ịkpọtụrụ ikuku ozugbo.Ekwesịrị imegharị sieves molecular nke na-etinye mmiri n'ime mmiri mgbe e debere ya ogologo oge.Sives molekụla na-ezere mmanụ na mmiri mmiri mmiri.Gbalịa izere ịkpọtụrụ mmanụ na mmiri mmiri n'oge eji.The gas maka ihicha ọgwụgwọ na ụlọ ọrụ mmepụta ihe na-agụnye ikuku, hydrogen, argon, wdg abụọ adsorption dryers jikọtara n'otu n'otu, otu na-arụ ọrụ na nke ọzọ nwere ike na-emegharị.Iji kwe ka ọrụ ahụ na-aga n'ihu na-aga n'ihu, ha na-atụgharị na ibe ha.Dryer na-arụ ọrụ na okpomọkụ nkịtị, ma na-arụkwa nrụpụta ikuku ikuku na okpomọkụ karịrị 340 ° C.
Usoro na ụkpụrụ nke molecular sieve akpịrị ịkpọ nkụ
akpịrị ịkpọ nkụ bụ usoro mgbasa ozi anụ ahụ.Mgbasa ozi gas na-abụkarị site na ike ndọda nke Fan ma ọ bụ ike mgbasa.Mgbasa ozi gas dị ka condensation nke gas.Ọ bụghị n'ozuzu ahọpụtara ma bụrụ usoro ntụgharị.Okpomọkụ nke adsorption dị ntakịrị na ike ịgbalite chọrọ maka mgbasa ozi dị ntakịrị, ya mere ngwa ngwa mgbasa ozi ngwa ngwa, dị mfe iji nweta nguzozi.
