Isebenza njani ingcinezelo Umsebenzi we-adsortion?
Xa uvelisa eyakho i-nitrogen, kubalulekile ukwazi kwaye uqonde inqanaba lokucoceka ofuna ukufezekisa. Ezinye izicelo zifuna amanqanaba acocekileyo acocekileyo (phakathi kwe-90 ne-99%), njengokunyuka kwamandla etay kunye nokuthintelwa komlilo okanye ukubumba kweplastiki, kufuna amanqanaba aphezulu (ukusuka kwi-97 ukuya kwi-99.999%). Kwezi meko iTekhnoloji ye-PSDA yeyona ndlela ifanelekileyo yokuhamba.
Eyona nto iphambili i-nitrogen generage isebenza ngokwahlula-hlula iimolekyuli ze-nitrogen kwiimolekyuli zeoksijini ngaphakathi komoya oxinzelelweyo. Ingcinezelo ye-swing adsorction iyona ngokuhamba ngeoksijini evela kumthombo womoya ophumileyo usebenzisa i-adlorption. I-Adsorvoction yenzeka xa iimolekyuli zizibophelela kwi-adsorblen, kule meko iimolekyuli zeoksijini zinamathela kwi-carbon moleth sieve (i-CMS). Oku kwenzeka kwiinqanawa ezimbini ezahlukeneyo zoxinzelelo, nganye izaliswe yi-CMS, etshintshela phakathi kwenkqubo yokwahluka kunye nenkqubo yokuphinda ihlaziyiwe. Okwangoku, mayibize i-Torce A neyeker B.
Abaqaqambileyo, abacocekileyo kwaye bomile i-Air Adter Engey tower A kwaye kuba iimolekyuli zeoksijini zincinci kunemolekyuli ze-nitrogen, ziya kungena kwi-pores ye-carbon sieve. Iimolekyuli ze-nitrogen kwelinye icala azinakulunga kwiipores ukuze zidlule i-scerbon moleve. Ngenxa yoko, uphela nge-nitrogen yococeko olufunwayo. Eli nqanaba libizwa ngokuba yiSigaba se-adsortion okanye isigaba sokwahlulahlula.
Ayimisi apho. Uninzi lwe-nitrojeni ye-nitrogen eveliswe kwinqaba i-Trace Aff Inkqubo (ilungele ukusetyenziswa ngqo okanye ukugcinwa), ngelixa inxenye encinci ye-nitrogen ye-nitrogen iflethi (ukusuka phezulu ukuya ezantsi). Oku kuhamba kuyafuneka ukukhupha ioksijini eyathinjwa kwisigaba se-Adch B. Ngokukhupha uxinzelelo kwiNqaba le-Borct B, i-carbon molersul ilahlekelwe yimolekyuli yeoksijini. Ziya kuhlasela kwizikhuselo kwaye zithathwe ngokupheliswa kukuhamba kwe-nitrogen A. Ngokwenza ukuba inkqubo yenze igumbi leemolekyuli zeoksijini ezintsha. Siyibiza ngokuba yi 'Ukucoca' i-oxygen ye-oxygen ye-oxygen egcweleyo.
Okokuqala, itanki a ikwisigaba se-Arsorvo ngelixa itanki iphinde yenziwa. Kwinqanaba lesibini zombini iinqanawa ezilinganayo ukuba zilungiselele ukutshintshela. Emva kokutshintsha, itanki iqala ukuphinda iphinde iphinde iphinde idlule ngelixa itanki ivelisa initrogen.
Okwangoku, uxinzelelo kuzo zombini iitora luya kulingana kwaye baya kutshintsha isigaba soku-adyving ukuvelisa kwakhona kunye ne-vice verda. I-CMS ye-CMS As toweli i-And iya kugcwala, ngelixa inqaba b, ngenxa yoxinzelelo, iya kuba nakho ukuqalisa inkqubo ye-adsen. Le nkqubo ikwabizwa ngokuba 'kukutshintshwa koxinzelelo', oko kuthetha ukuba ivumela iigesi ezithile ukuba zifakwe kuxinzelelo oluphezulu kwaye zikhutshwe ngoxinzelelo olusezantsi. Inkqubo yesibini ye-PASTA ivumela ukuveliswa kwe-witrogen eqhubekayo kwinqanaba lokucoceka okufunwayo.
