Momwe mungachotsere madzi pambuyo pa 4A molecular sieve dehydration

2022-12-30

Mayamwidwe amadzi a molecular sieve amatengera zomwe zili m'madzi a chinthucho, malangizo ochotsa madzi a molekyulu 4A.

1. Kagwiritsidwe: 4A molecular sieve ili ndi mphamvu yosankha adsorption ndipo imatha kuchotsa chinyezi muzosungunulira zamoyo ndi mpweya, koma sichimasokoneza zosungunulira ndi mpweya (monga tetrahydrofuran).The njira choyambirira utenga caustic koloko madzi m'thupi, koloko ndi sungunuka m'madzi, si kophweka kupatukana ndi tetrahydrofuran pambuyo madzi m'thupi, amagwiritsa caustic koloko kukhala zovuta yobwezeretsanso, kwenikweni kuchuluka mtengo.

2. Njira yogwiritsira ntchito: Kutaya madzi m'thupi kwa 4A molecular sieve ndikosavuta.Sieve ya molekyulu imatha kuyikidwa mwachindunji muzosungunulira zosungunulira, kapena yankho ndi mpweya zitha kudutsa mu cell sieve adsorption tower.

3. Adsorption mphamvu: Molecular sieve 4A ali ndi mphamvu adsorption lalikulu, zambiri 22%.

4. Kusankhidwa kwa adsorption performance: 4A molekyulu sieve imatha kuyamwa mamolekyu amadzi mosavuta.Chifukwa m'mimba mwake mamolekyu amadzi ndi ocheperako kuposa zeolite, mphamvu ya electrostatic imatha kupezeka pambuyo pa adsorption (ma cell sieves samayamwa tinthu tating'onoting'ono tokulirapo kuposa masikelo a maselo).

5.Analysis popanda kupanga madzi: 4a molekyulu sieve sidzatulutsidwa pambuyo kuyamwa madzi kutentha firiji.

6. Kusinthika: Kusinthika kwa 4A molecular sieve ndikosavuta.Pambuyo pa ola limodzi, nayitrogeni wopitilira 300 ° C atha kugwiritsidwanso ntchito (zinthu zosayaka zimatha kuponyedwa mumlengalenga).

7. Moyo wautali wautumiki: 4Sieve ya molekyulu imatha kupangidwanso kwa zaka 3-4.

Masieve a ma molekyulu ali ndi hygroscopicity yamphamvu ku chinyezi, choncho ayenera kugwiritsidwa ntchito poyeretsa mpweya ndipo sayenera kukhudzana mwachindunji ndi mpweya.Sieve ya mamolekyulu yomwe yatenga chinyezi iyenera kupangidwanso pambuyo posungidwa kwa nthawi yayitali.Ma molekyulu sieves amapewa mafuta ndi madzi amadzimadzi.Yesetsani kupewa kukhudzana ndi mafuta ndi madzi amadzimadzi panthawi yogwiritsira ntchito.Mipweya yowumitsa mankhwala muzinthu zamafakitale imaphatikizapo mpweya, haidrojeni, argon, ndi zina zotero. Zowumitsira ziwiri za adsorption zimagwirizanitsidwa mofanana, ntchito imodzi ndi ina ikhoza kusinthidwa.Pofuna kulola kuti zipangizozi zizigwiritsidwa ntchito mosalekeza, zimasinthana wina ndi mzake.Chowumitsira chimagwira ntchito kutentha kwanthawi zonse, ndipo chimachapiranso mpweya pa kutentha pamwamba pa 340 ° C.

The ndondomeko ndi mfundo ya maselo sieve kuchepa madzi m'thupi

Kutaya madzi m'thupi ndi njira yowonetsera thupi.Kukokera kwa gasi kumayambitsidwa makamaka ndi mphamvu yokoka ya Fani kapena mphamvu ya kufalikira.Kutengera kwa gasi ndikofanana ndi kukhazikika kwa gasi.Nthawi zambiri sichisankha ndipo ndi njira yosinthira.Kutentha kwa adsorption ndikochepa ndipo mphamvu yotsegulira yofunikira kuti adsorption ndi yochepa, kotero kuthamanga kwa adsorption Mofulumira, kosavuta kukwaniritsa bwino.
