Isikhokelo esipheleleyo soMgaqo oSebenzayo weeJeneretha zeNitrogen zePSA

Ijenereyitha ye-nitrogen ye-PSA idla ngokuba sisisombululo sokubonelela rhoqo nge-nitrogen ngaphandle kwesidingo sokuthenga iisilinda rhoqo. Yahlula i-nitrogen ne-oxygen kwindawo, isebenzisa umoya oqhelekileyo, ukuhlangabezana neemfuno zamashishini ukuze kubekho unikezelo olukhuselekileyo lwegesi ukuba kuyimfuneko. Oku kusetyenziswa rhoqo kwiifektri zokupakisha ukutya, iifektri zokusika nge-laser, kwaneefektri ze-elektroniki. Iinkampani zinokukhetha ukuvelisa i-nitrogen xa ifuneka kwaye zingalindeli ukuhanjiswa kwayo. Kulula kodwa ingqiqo engasemva kwayo ikrelekrele kancinci kwaye kunokuba luncedo ukuyihlola inyathelo ngenyathelo.

Ingcamango Esisiseko Yokwahlulwa Komoya Kwimveliso YeNitrogen

Ingcinga ephambili emva kwejenereyitha ye-nitrogen ye-PSA kukukwazi ukwahlula i-nitrogen (N2) kwezinye iigesi emoyeni, ikakhulu ioksijini. Iqala ngomoya oqhelekileyo ovela emoyeni. Umoya uyacinezelwa, okanye ufakwe kwindawo encinci apho iigesi zilawulwa lula kwaye zinokushukunyiswa kwinkqubo. Umoya uyacinezelwa kwaye udlula kwisihluzo se-carbon molecular esikhethekileyo ukuze usicinezele. Iimbobo zale nto zincinci kakhulu kwaye zikhetha kakhulu. Iimolekyuli zeoksijini zincinci kancinci kuneemolekyuli ze-N₂ kwaye zihamba ngendlela eyahlukileyo kancinci, ngoko ke zinokubanjwa lula kwisihluzo. Nangona kunjalo, iimolekyuli ze-nitrogen ziyadlula kwaye ziqhubeke. Ngokwesiqhelo ezimbini zezi tanki ziya kusebenza. Elinye itanki liya kucocwa kwaye liphinde lisetyenziswe kwaye itanki yeoksijini iya kuqokelelwa. Inxalenye "yokujika koxinzelelo" yenkqubo kukutshintshana phakathi kwezi zimbini. Elinye icala liphantsi koxinzelelo oluphezulu ukuze lahlule iigesi kwaye emva koko uxinzelelo luyancitshiswa, ukuze ioksijini isuswe kumgibe. Inkqubo iyaphindwa. Ngale ndlela yokutshintsha, i-nitrogen igcinwa ijikeleza rhoqo. Esi sisizathu sokuba amashishini aqinisekise ukuba iya kusetyenziswa rhoqo. I-nitrogen isetyenziswa kumgca wokupakisha ukutya ukususa ioksijini ngaphakathi kwiipakethe ezivaliweyo ukwandisa ubomi beshelufu yezidlo ezityiwayo kunye nezinye iimveliso zokutya. Kwiiworkshop zokusika nge-laser, i-nitrogen isetyenziselwa ukuzikhusela ekutshisweni okanye ekufakweni kwesinyithi ukuze kucoceke iziqwenga. Imfihlo yokuphila kukuba akukho ziphumo zinzima ezibandakanyekayo kwaye akukho khemikhali zisetyenziswayo. Ifuna kuphela ukusetyenziswa komoya, utshintsho loxinzelelo kunye nezinto zokufunxa. Inkqubo icwangcisiwe kwaye ukusebenza kwayo kugcinwa njengoko kuyimfuneko ngolawulo lokuhamba komoya. Ngamazwi alula, PSA nitrogen jenereyitha sisihluzo esikrelekrele esikwaziyo "ukuthintela" ioksijini kwaye sivumele i-nitrogen ukuba idlule.

Indlela ii-Carbon Molecular Sies ezihlula ngayo i-oksijini kunye ne-nitrogen

Kwinkqubo ye-nitrogen ye-PSA, "umsebenzi" wenziwa kwisixhobo esaziwa ngokuba yi-carbon molecular sieve, okanye i-CMS nje. Ifana nee-granules ezincinci ezimnyama, kodwa inee-pores ezininzi ezincinci ngaphakathi kwikhozo ngalinye ukulawula ukuhamba kweegesi. Umoya uqulathe izinto ze-nitrogen kunye ne-oxygen ezineempawu ezahlukeneyo xa zixinzelelwe kwiindawo ezimxinwa. Iimolekyuli ze-oxygen zisebenza kancinci kwaye zihamba ngendlela evumela ukuba zibanjwe kwii-pores ezincinci kakhulu ze-CMS. Nangona kunjalo, iimolekyuli ze-nitrogen "zityibilika", kwaye zinokudlula ngokulula. Ibhedi ye-CMS icinezelwe ngumoya oxinzelelweyo, ngaloo ndlela iqhuba i-oxygen kunye ne-nitrogen ebhedini. Ukuba i-oxygen ayivumelekanga ukuba idlule kwii-pores, iya kuhlala ngaphakathi kwesakhiwo. Oku kubizwa ngokuba yi-adsorption xa iimolekyuli zegesi zinamathela kumphezulu wezinto. Igesi yemveliso ine-nitrogen, eqhubeka idlula kwaye iphume kwinkqubo. Umfanekiso olungileyo ekufuneka uwukhumbule "yipaseji" enabantu abaninzi kuyo kunye nomnyango omncinci. I-oxygen ifana nabantu abaneengxowa ezinkulu phambi kwabo ezinamathele emnyango; I-nitrogen ifana nabantu abaneengxowa ezincinci phambi kwabo kwaye ingena kakuhle. Inkqubo ayixhomekekanga kwibhedi enye yesihluzo. Ibhedi enye isetyenziselwa ukubamba ioksijini kwaye enye ivulwa umoya ukuze ikhulule ioksijini ebanjiweyo kwaye iyisuse. Linqanaba lokuseta kwakhona elibalulekileyo kuba livumela isihluzo ukuba sisebenze kwakhona. Emva koko iyatshintshana phakathi kweebhedi ezimbini. Lo ngumjikelo oqhubekayo obalulekileyo ukugcina imveliso ye-N ezinzileyo. Oku kunokuvela kwindawo yokusika nge-laser apho kufuneka khona ukuhamba kwe-nitrogen ecocekileyo ukuthintela isinyithi ekungcoliseni okusetyenziswayo. I-CMS isusa ioksijini ngaphambi kokuba ioksijini ifike kwizixhobo, nto leyo enegalelo ekugcinweni kwemiphetho yokusika ecocekileyo. I-CMS iyasebenza kakhulu kungekuphela nje kumxholo, kodwa kuba isebenza phantsi koxinzelelo. Iba luhlobo lwesihluzo esizihlaziya rhoqo kwaye sivelise i-nitrogen ngaphandle kokuphazamiseka.

Inkqubo Epheleleyo Yokusebenza kwe-Dual-Tower Pressure Swing Adsorption

Inkqubo yokufunxa i-pressure swing dual tower yenzelwe ukugcina ukuhamba okuqhubekayo kwe-nitrogen. Ineenqaba ezimbini eziqulathe inani elifanayo le-carbon molecular seeve, ezisetyenziselwa ukwenza inkqubo yokwahlula umoya. Umjikelo uqala xa umoya ocinezelweyo ungena kwinqaba yokuqala. Xa uxinzelelo luphezulu, ngaphakathi kwee-molecule ze-oksijini zinamathela kwizinto ezikwisihluzo. I-nitrogen ayibanjwanga lula kwaye idlula kwinqaba kwaye iphume njengegesi yemveliso. Iindima emva koko ziyatshintsha emva kwexesha elifutshane. Inqaba yokuqala iqala ukukhulula uxinzelelo kwaye iqala ukuhlaziywa kwaye inqaba yesibini iqala ukuvelisa i-nitrogen. Olu tshintsho lulawulwa ukuba lwenzeke ngesigqi esilawulwayo, ngokuqhelekileyo ngokulandelelana kwemizuzwana, kwaye ngaloo ndlela imveliso ihlala izinzile. Oku kunokuboniswa njengabasebenzi ababini abaneshedyuli yokutshintsha. Omnye usekwimveliso kwaye omnye uphumle, elungiselela umjikelo olandelayo. Bayatshintshana, ngoko akukho kumiswa kwimveliso.

Intshayelelo kwimisebenzi yeCandelo ngalinye kwiNkqubo yePSA

Inkqubo ye-nitrogen ye-PSA ifana netsheyini, enomxokelelwane ngamnye onomsebenzi wayo othile. Ukusilela kwenxalenye enye ekusebenzeni umsebenzi wayo kuthetha ukuba yonke inkqubo ayizinzanga. Ukwazi ezi nxalenye kukuvumela ukuba uqonde ngokulula imveliso ye-nitrogen xa kufuneka. Ngokwesiqhelo, kuqala ngokungasebenzi kakuhle kwe-compressor yomoya. Le yunithi itsala umoya oqhelekileyo kwaye iwucinezele kuxinzelelo olufanelekileyo. Ukuba eli nyathelo alithathwanga, umoya uya kuba buthathaka kakhulu ukuba ungasetyenziswa kwinkqubo yokwahlula. Umoya ocinezelweyo usashushu kwaye unokuba ngamanzi okanye uthuli. Kulapho icandelo lonyango lomoya lingena khona. Izihluzi kunye nezomisi zicoca umoya ngaphambi kokuba ungene kwinkqubo ephambili. Le nkqubo inceda ukugcina isihluzo se-carbon molecular kunye nokugcina uzinzo lokusebenza ngokuhamba kwexesha ngenxa yokususwa kothuli kunye nomphunga wamanzi. Okulandelayo yitanki ye-Air Receiver. Oku kufana ne-buffer. Isusa naluphi na uxinano ekuhambeni komoya kwiyunithi ye-PSA, iqinisekisa umsinga ozinzileyo womoya ocinezelweyo. Oku kunceda ekugcineni uxinzelelo ngexesha lokusebenza. Okulandelayo, inxalenye ephambili yenkqubo ziinqaba ezimbini zokufunxa ezigcwele ii-carbon molecular sieves. Iinqaba ezimbini zokufunxa eziqulathe ii-carbon molecular sies ke yintliziyo yenkqubo. Ezi nqaba ziyatshintshana ekwahlulweni kweoksijini kwi-nitrogen. Enye inqaba ivelisa iNitrogen kwaye enye iyacocwa kwaye iphinda isetyenziswe. Olu tshintsho luqinisekisa ukuba imveliso ayiphazamiseki.

Izinto Eziphambili Ezichaphazela Ukucoceka KweNitrogen kunye Nezinga Lokuhamba KweeNqanaba

Ubungakanani benitrogen ecocekileyo kunye nesantya ephuma ngaso kwinkqubo yePSA azinakulinganiswa. Ziya kwahluka ngokwendawo ebekwe kuyo kunye nokusetyenziswa kwenkqubo. Kukho iinkalo ezimbalwa ezibalulekileyo ezidlala indima enkulu ekucocekeni kwegesi ye-N2 kunye nokuba ingakanani igesi enokwenziwa ngomlinganiselo othile. Enye yezona zinto zibalulekileyo luxinzelelo lomoya. PSA izixhobo nitrogen generator Inkqubo kufuneka ibe nomlinganiselo ofanelekileyo woxinzelelo ukuqinisekisa ukuba igesi yeoksijini ingena kwisihluzo se-carbon molecular. Uxinzelelo olunganelanga aluncedi ekuhlukaniseni ioksijini kwaye lunciphisa ubunyulu be-nitrogen. Ukuba iphezulu kakhulu, kukho ithuba lokuba inkqubo ilahlekelwe ngamandla ngaphandle kokuvelisa imveliso eninzi. Eyona ndlela ixhaphakileyo kukutshintsha uxinzelelo ukuze ufumane ibhalansi echanekileyo. Enye yindlela umoya oza kuhamba ngayo ngesantya esiphezulu. Izixa zegesi ezininzi kakhulu zifakwa ngexesha elinye, nto leyo enganelanga ukuvumela isihluzo ukuba sisebenze ngokuchanekileyo. Oku kunokubangela ukuba umgangatho we-nitrogen unciphe. Kodwa kwiimeko zomoya ophantsi, ukunqongophala kwemveliso kunye nokungasebenzi kakuhle kunokwenzeka. Naluphi na ulungelelwaniso lobunyulu kunye nesantya.
