I-industrial oxygen generatorsebenzisa i-zeolite molecular sieve njenge-adsorbent futhi usebenzise i-pressure adsorption, isimiso sokucindezela i-desorption esivela ku-air adsorption futhi ukhulule umoya-mpilo. I-Zeolite molecular sieve iwuhlobo lwe-adsorbent eyindilinga eyindilinga enama-micropores ngaphezulu nangaphakathi, futhi imhlophe. Izici zayo zokudlula ziyenza ikwazi ukuthola ukuhlukaniswa kwe-kinetic kwe-O2 ne-N2. Umthelela wokuhlukanisa we-zeolite molecular sieve ku-O2 ne-N2 usekelwe emehlukweni omncane wamadiamitha we-kinetic wamagesi amabili. I-molecule ye-N2 inezinga lokusabalalisa ngokushesha kuma-micropores we-zeolite molecular sieve, kuyilapho i-molecule ye-O2 inezinga lokusabalalisa elihamba kancane. Ukusatshalaliswa kwamanzi kanye ne-CO2 emoyeni ocindezelwe akuhlukile kakhulu kulokho kwe-nitrogen. Okugcina kuphuma embhoshongweni we-adsorption ama-molecule e-oxygen. I-adsorption ye-pressure swingukukhiqizwa kwe-oxygenukusetshenziswa kwezici ze-zeolite ze-molecular sieve adsorption, ukusetshenziswa kwe-pressure adsorption, umjikelezo we-desorption, umoya ocindezelwe ngokushintshana embhoshongweni we-adsorption ukufeza ukuhlukaniswa komoya, ukuze ukhiqize umoya-mpilo ngokuqhubekayo.
1. Iyunithi yokuhlanza umoya ecindezelwe
Umoya ocindezelwe ohlinzekwa yi-compressor yomoya uqale udlulele engxenyeni yokuhlanza umoya ocindezelweyo, futhi umoya ocindezelwe ukhishwa kuqala ngesihlungi sepayipi ingxenye enkulu kawoyela, amanzi nothuli, bese uqhubeka ukhishwa umshini wokomisa, isihlungi esihle. ukususwa kwamafutha kanye nokususwa kothuli, futhi isihlungi se-ultra-fine silandelwa ukuhlanzwa okujulile. Ngokwesimo sokusebenza kwesistimu, i-TCWY yaklama ngokukhethekile isethi yomshini wokukhipha umoya ocindezelwe ukuze kuvinjwe ukungena okungaba khona kukawoyela wokulandela umkhondo futhi inikeze ukuvikeleka okwanele kwesisefo samangqamuzana. Izingxenye zokuhlanza umoya eziklanywe ngokucophelela ziqinisekisa impilo yesevisi ye-sieve yamangqamuzana. Umoya ohlanzekile ophathwa yilo mhlangano ungasetshenziselwa umoya wezinsimbi.
2. Ithangi lokugcina umoya
Iqhaza lethangi lokugcina komoya lithi: nciphisa ukushaywa komoya, dlala indima yesivikelo; Ngakho-ke, ukuguquguquka kwengcindezi yesistimu kuncishisiwe, ukuze umoya ocindezelwe udlule engxenyeni yokuhlanza umoya ocindezelwe kahle, ukuze ususe ngokugcwele ukungcola kwamafutha namanzi, futhi unciphise umthwalo we-PSA eyalandela idivayisi yokuhlukanisa i-oxygen ne-nitrogen. Ngesikhathi esifanayo, lapho umbhoshongo we-adsorption ushintshwa, futhi uhlinzeka ngenani elikhulu lomoya ocindezelwe we-PSA oksijini kanye ne-nitrogen yokuhlukanisa idivayisi ukuze ikhulise ngokushesha ingcindezi ngesikhathi esifushane, ukuze ingcindezi embhoshongweni we-adsorption ikhuphuke ngokushesha ingcindezi yokusebenza, ukuqinisekisa ukusebenza okuthembekile nokuzinzile kwemishini.
3. Ithuluzi lokuhlukanisa i-oxygen ne-nitrogen
Umbhoshongo we-adsorption ofakwe ngesisefo esikhethekile se-molecular unezimbili, u-A no-B. Lapho umoya ohlanzekile ocindezelwe ungena ekugcineni kwe-inlet yombhoshongo A futhi ugeleza ngesisefo se-molecular uye ekugcineni kokuphuma, i-N2 ikhangiswa yiyo, futhi ioksijini yomkhiqizo iyaphuma. kusukela ekugcineni kokuphuma kombhoshongo we-adsorption. Ngemva kwesikhathi esithile, isisefo samangqamuzana ku-Tower A sasigcwele i-adsorption. Ngalesi sikhathi, umbhoshongo A umisa ngokuzenzakalelayo ukukhangiswa, umoya ocindezelwe ugeleza ungene ku-Tower B ukuze uthole ukumuncwa kwe-nitrogen nokukhiqizwa komoyampilo, futhi isisefo se-molecular of Tower A siyavuselelwa. Ukuvuselelwa kwesisefo samangqamuzana kufinyelelwa ngokuwisa ngokushesha umbhoshongo we-adsorption kungcindezi yasemkhathini ukuze kukhishwe i-adsorbed N2. Imibhoshongo emibili ikhangiswa ngokushintshana futhi ivuselelwe ukuze kuqedelwe ukuhlukaniswa komoyampilo ne-nitrogen kanye nokuphuma okuqhubekayo komoyampilo. Izinqubo ezingenhla zilawulwa isilawuli se-programmable logic (PLC). Lapho ukuhlanzeka kwe-oksijeni kokuphela kwe-outlet kusethiwe, uhlelo lwe-PLC lusebenza, i-valve yokukhipha umoya othomathikhi iyavulwa, futhi umoya-mpilo ongafanelekile uthululwa ngokuzenzakalelayo ukuze kuqinisekiswe ukuthi i-oxygen engafanelekile ayigelezi endaweni yegesi. Lapho igesi ikhipha umoya, umsindo ungaphansi kuka-75dBA ngokusebenzisa isithulisi.
4. I-oxygen buffer tank
Ithangi le-oxygen buffer lisetshenziselwa ukulinganisa ukucindezela nokuhlanzeka komoya-mpilo ohlukaniswe nesistimu yokuhlukanisa umoya-mpilo we-nitrogen ukuze kuqinisekiswe ukuzinza kokunikezwa okuqhubekayo komoya-mpilo. Ngesikhathi esifanayo, ngemva kokushintshwa komsebenzi wombhoshongo we-adsorption, uzogcwalisa ingxenye yegesi yawo emuva embhoshongweni we-adsorption, ngakolunye uhlangothi ukusiza ukucindezela kombhoshongo we-adsorption, kodwa futhi ubambe iqhaza ekuvikeleni umbhede, futhi udlale indima ebaluleke kakhulu yosizo lwenqubo ohlelweni lokusebenza lwemishini.
