Izici zomkhiqizo we-PSA nitrogen generator

Ngokuthuthuka okusheshayo kwezimboni, i-nitrogen isetshenziswe kabanzi emkhakheni wamakhemikhali, i-electronics, i-metallurgy, ukudla, imishini, njll. Isidingo se-nitrogen ezweni lami sikhula ngezinga elingaphezu kuka-8% njalo ngonyaka.I-nitrogen ayisebenzi ngamakhemikhali, futhi ayisebenzi kakhulu ngaphansi kwezimo ezijwayelekile, futhi akulula ukusabela ngamakhemikhali nezinye izinto.Ngakho-ke, i-nitrogen isetshenziswa kabanzi njengokuvikela igesi kanye negesi yokuvala embonini ye-metallurgical, imboni ye-electronics, kanye nemboni yamakhemikhali.Ngokuvamile, ukuhlanzeka kwegesi evikelayo kungu-99.99%, kanti ezinye zidinga i-nitrogen ehlanzekile engaphezu kuka-99.998%.I-nitrogen ewuketshezi iwumthombo obandayo ofaneleka kakhudlwana, futhi isetshenziswa kakhulu embonini yokudla, embonini yezokwelapha, kanye nokugcinwa kwesidoda sokufuywa kwezilwane.Ekukhiqizeni i-ammonia yokwenziwa embonini yomanyolo wamakhemikhali, uma igesi eluhlaza ye-synthetic ammonia-hydrogen negesi exutshwe ne-nitrogen igezwa futhi icwengwe nge-nitrogen ewuketshezi ehlanzekile, okuqukethwe kwegesi ye-inert kungaba kuncane kakhulu, futhi okuqukethwe yisulfure. i-monoxide ne-oxygen ayidluli ama-20 ppm.

I-nitrogen ehlanzekile ayikwazi ukudonswa ngokuqondile emvelweni, futhi ukuhlukaniswa komoya kusetshenziswa kakhulu.Izindlela zokuhlukanisa umoya zihlanganisa: indlela ye-cryogenic, indlela ye-press swing adsorption (PSA), indlela yokuhlukanisa ulwelwesi.

Isingeniso senqubo kanye nemishini ye-PSA nitrogen generator

Isingeniso sokugeleza kwenqubo

Umoya ungena ku-compressor yomoya ngemva kokukhipha uthuli nokungcola kwemishini ngokusebenzisa isihlungi somoya, futhi ucindezelwe kungcindezi edingekayo.Ngemuva kokwelashwa okuqinile kokwehlisa amafutha, ukususa amanzi, nokususa uthuli, kuphuma umoya ocindezelwe ohlanzekile ukuze kuqinisekiswe ukusetshenziswa kwezisefo zamangqamuzana kumbhoshongo we-adsorption.ukuphila.

Kunemibhoshongo emibili ye-adsorption ene-carbon molecular sieve.Lapho umbhoshongo owodwa usebenza, omunye umbhoshongo uyacindezelwa ukuze unciphe.Umoya ohlanzekile ungena embhoshongweni we-adsorption osebenzayo, futhi lapho udlula esisefweni samangqamuzana, umoya-mpilo, i-carbon dioxide namanzi kukhangiswa ngawo.Igesi eligeleza ekugcineni yi-nitrogen futhi lilandele amanani e-argon ne-oxygen.

Omunye umbhoshongo (umbhoshongo we-desorption) uhlukanisa i-oksijini ekhangayo, i-carbon dioxide namanzi ezimbotsheni ze-molecular sieve futhi ikhiphe emkhathini.Ngale ndlela, le mibhoshongo emibili yenziwa ngokushintshana ukuze iqedele ukuhlukaniswa kwe-nitrogen ne-oxygen futhi iqhubeke nokukhipha i-nitrogen.Ukuhlanzeka kwe-nitrogen ekhiqizwa i-pressure swing (_bian4 ya1) i-adsorption ingu-95% -99.9%.Uma kudingeka i-nitrogen ehlanzekile, imishini yokuhlanza i-nitrogen kufanele yengezwe.

I-nitrogen engu-95% -99.9% ephuma ku-pressure swing adsorption generator i-nitrogen ingena emishinini yokuhlanza i-nitrogen, futhi ngesikhathi esifanayo inani elifanele le-hydrogen lengezwa nge-flowmeter, futhi i-hydrogen kanye ne-trace oxygen ku-nitrogen kusabela ngendlela enamandla umbhoshongo we-deoxygenation wemishini yokuhlanza ukuze ususe I-oksijeni bese ipholiswa yi-condenser yamanzi, isihlukanisi samanzi esimusi sichithwa, bese somiswa ngokujulile ngesomisi (imibhoshongo emibili yokumisa i-adsorption isetshenziswa ngokushintshana: eyodwa isetshenziselwa ukukhangisa futhi ukomisa ukuze kukhishwe amanzi, enye iyashiswa ukuze i-desorption kanye ne-drainage ukuze ithole i-nitrogen ehlanzekile kakhulu ingafinyelela ku-99.9995%.
