Ijenereyitha yeoksijini yeshishiniYamkela i-zeolite ye-molecular sieve njenge-adsorbent kwaye usebenzise i-adsorption yoxinzelelo, umgaqo woxinzelelo we-desorption kwi-adsorption yomoya kunye nokukhulula i-oksijini. I-Zeolite molecular sieve luhlobo lwe-spherical granular adsorbent ene-micropores kumphezulu nangaphakathi, kwaye imhlophe. Iimpawu zayo zokupasa zivumela ukuba kufezekiswe ukuhlukana kwe-kinetic ye-O2 kunye ne-N2. Isiphumo sokuhlukana kwe-zeolite ye-molecular sieve kwi-O2 kunye ne-N2 isekelwe kumahluko omncinci we-kinetic diameters yeegesi ezimbini. I-molecule ye-N2 inesantya sokusasazwa ngokukhawuleza kwi-micropores ye-zeolite molecular sieve, ngelixa i-molecule ye-O2 inezinga eliphantsi lokusasaza. Ukusasazwa kwamanzi kunye ne-CO2 kumoya oxinanisiweyo akufani kakhulu naleyo yenitrogen. Oko ekugqibeleni kuphuma kwinqaba ye-adsorption ziimolekyuli zeoksijini. Uxinzelelo lwe-swing adsorptionukuveliswa kweoksijinikukusetyenziswa kweempawu ze-zeolite ze-molecular sieve zokukhetha i-adsorption, ukusetyenziswa kwe-adsorption yoxinzelelo, umjikelo we-desorption, umoya oxinzelelweyo ngokutshintshela kwi-adsorption tower ukuphumeza ukwahlukana komoya, ukwenzela ukuba uvelise i-oksijini ngokuqhubekayo.
1. Iyunithi yokucoca umoya ecinezelweyo
Umoya oxinanisiweyo obonelelwa sisicinezeli somoya kuqala ugqithiselwe kwicandelo lokucoca umoya, kwaye umoya ocinezelweyo uqala ususwe sisihluzo sombhobho uninzi lweoyile, amanzi kunye nothuli, kwaye emva koko ususwe kwakhona sisisomisi esinomkhenkce, isihluzo esihle. ukususwa kweoli kunye nokususwa kothuli, kunye ne-ultra-fine filter ilandelwa kukuhlanjululwa okunzulu. Ngokwemeko yokusebenza kwenkqubo, i-TCWY yenzelwe ngokukodwa iseti ye-degreaser yomoya ecinezelekileyo ukuthintela ukungena kwe-oyile enokwenzeka kunye nokubonelela ngokhuseleko olwaneleyo lwe-molecular sieve. Amacandelo okucoca umoya ngokucokisekileyo aqinisekisa ubomi benkonzo ye-molecular sieve. Umoya ococekileyo ophathwa yile ndibano ungasetyenziselwa umoya wesixhobo.
2. Itanki yokugcina umoya
Indima yetanki yokugcina umoya yile: nciphisa i-airflow pulsation, dlala indima yesithinteli; Ngaloo ndlela, ukuguquguquka koxinzelelo lwenkqubo kuncitshisiwe, ukwenzela ukuba umoya ocinezelweyo udlule kwindawo yokucoca umoya ngokucokisekileyo, ukuze ususe ngokupheleleyo ukungcola kweoli kunye namanzi, kunye nokunciphisa umthwalo we-PSA elandelayo ye-oksijini kunye nesixhobo sokwahlula i-nitrogen. Kwangaxeshanye, xa i-adsorption tower itshintshelwa, ikwabonelela ngomthamo omkhulu womoya oxinanisiweyo we-PSA oksijini kunye nesixhobo sokwahlula initrogen ukuze inyuse ngokukhawuleza uxinzelelo ngexesha elifutshane, ukuze uxinzelelo kwinqaba ye-adsorption iphakame ngokukhawuleza. uxinzelelo lokusebenza, ukuqinisekisa ukusebenza okuthembekileyo kunye nokuzinza kwezixhobo.
3. Isixhobo sokwahlula ioksijini kunye nenitrogen
Inqaba ye-adsorption exhotywe nge-sieve ekhethekileyo ye-molecular inezimbini, i-A kunye ne-B. Xa umoya ococekileyo ocinezelweyo ungena kwi-inlet end of tower A kwaye uhamba nge-molecular sieve ukuya ekupheleni kokuphuma, i-N2 ibhengezwa yiyo, kwaye i-oksijeni yemveliso iphuma ngaphandle. ukusuka ekupheleni kwe-adsorption tower. Emva kwexesha elithile, i-molecular sieve kwi-Tower A yahluthwa yi-adsorption. Ngeli xesha, inqaba A iyayeka ngokuzenzekelayo iadsorption, umoya ocinezelweyo uqukuqela ungene kwiNqaba B yokufunxa initrogen kunye nemveliso yeoksijini, kunye nesefo yemolekyuli yeNqaba A ihlaziywa. Ukuhlaziywa kwe-molecular sieve kufezekiswa ngokukhawuleza ukulahla i-adsorption tower kwi-atmospheric pressure ukususa i-adsorbed N2. Iinqaba ezimbini zibhengezwa ngokuhlukileyo kwaye zihlaziywa ngokutsha ukuze zigqibe ukuhlukana kwe-oksijini kunye ne-nitrogen kunye nokuphuma okuqhubekayo kwe-oksijini. Ezi nkqubo zingentla zilawulwa yi-programmable logic controller (PLC). Xa ukucoceka kwe-oksijini yokuphela kwe-outlet kumiselwe, inkqubo ye-PLC isebenza, i-valve ye-vent ngokuzenzekelayo ivuliwe, kwaye i-oksijini engafanelekanga ikhutshwe ngokuzenzekelayo ukuze kuqinisekiswe ukuba i-oksijini engafanelekanga ayiqhubeki kwindawo yegesi. Xa igesi iphuma, ingxolo ingaphantsi kwe-75dBA ngokusebenzisa isithulisi.
4. Itanki yesithinteli seoksijini
I-oxygen buffer tank isetyenziselwa ukulinganisela uxinzelelo kunye nokucoceka kwe-oksijini ehlukaniswe kwinkqubo yokwahlula i-nitrogen oksijini ukuze kuqinisekiswe ukuzinza kokunikezelwa kwe-oksijini okuqhubekayo. Ngelo xesha, emva kokuba umsebenzi we-adsorption tower utshintshiwe, uya kugcwalisa inxalenye yegesi yayo emva kwinqaba ye-adsorption, kwelinye icala ukunceda uxinzelelo lwe-adsorption tower, kodwa ludlala indima ekukhuseleni ibhedi, kwaye udlale indima ebaluleke kakhulu yokuncedisa inkqubo kwinkqubo yokusebenza yezixhobo.
