I-vacuum pressure swing adsorption (VPSA) iteknoloji yokuvelisa ioksijini yindlela esebenzayo neyonga amandla ukulungiselela ioksijini. Ifezekisa ukwahlukana kwe-oksijini kunye ne-nitrogen ngokusebenzisa i-adsorption ekhethiweyo ye-molecular sieves. Inkqubo yayo ibandakanya ikakhulu ezi khonkco zilandelayo:
1. Inkqubo yonyango yomoya okrwada
Uxinzelelo lomoya: Isivuthelo sicinezela umoya ojikelezayo ukuya malunga ne-63kPa (uxinzelelo lwegeyiji) ukunika amandla kwi-adsorption elandelayo. Inkqubo yoxinzelelo iya kuvelisa ubushushu obuphezulu, obufuna ukupholiswa kwinkqubo efunekayo yobushushu (malunga ne-5-40℃) ngesipholile samanzi.
Ukucocwa kwangaphambili: Isihluzo esinezigaba ezibini sisetyenziselwa ukususa ukungcola komatshini, kwaye isixhobo sokomisa sisetyenziselwa ukususa izinto ezingcolisayo ezifana nokufuma kunye ne-oyile ye-oyile ukukhusela i-molecular sieve adsorbent.
2. Inkqubo yokwahlula i-Adsorption
I-adsorption ye-Dual tower alternating: Inkqubo ixhotyiswe ngeenqaba ezimbini ze-adsorption ezixhotyiswe ngeesefu ze-molecular zeolite. Xa enye inqaba i-adsorbing, enye inqaba iyahlaziywa. Umoya ocinezelweyo ungena ukusuka ezantsi kwinqaba, kwaye i-molecular sieve ibhengeza ukungcola okufana nenitrogen kunye necarbon dioxide, kunye neoksijini (ubunyulu 90% -95%) iphuma phezulu kwinqaba.
Ulawulo loxinzelelo: Uxinzelelo lwe-adsorption luhlala lugcinwa ngaphantsi kwe-55kPa, kwaye ukutshintsha ngokuzenzekelayo kuphunyezwa ngeevalvu ze-pneumatic.
3. Inkqubo yokuncipha kunye nokuhlaziya
I-vacuum desorption: Emva kwe-saturation, impompo yokucoca inciphisa uxinzelelo kwinqaba ukuya kwi-50kPa, i-desorb i-nitrogen kwaye iyikhuphe kwi-exhaust muffler.
Ukuhlanjululwa kwe-oxygen: Kwinqanaba lokugqibela lokuvuselelwa, enye i-oksijini yemveliso yaziswa ukugungxula inqaba ye-adsorption ukuqhubela phambili ukuphucula ukusebenza kakuhle kwe-adsorption yomjikelo olandelayo.
4.Inkqubo yokulungisa imveliso
I-oxygen buffer: Iimveliso ze-oksijini ezingapheliyo zigcinwa kuqala kwi-tank ye-buffer (uxinzelelo lwe-14-49kPa), kwaye emva koko zinyanzeliswa kuxinzelelo olufunekayo lomsebenzisi nge-compressor.
Isiqinisekiso sobunyulu: Ngokusebenzisa izihluzi ezintle kunye nokulawula ukulinganisa ukuhamba, ukukhutshwa kwe-oksijini okuzinzileyo kuqinisekiswa.
5.Inkqubo yokulawula ehlakaniphile
Yamkela i-PLC ukufezekisa ukusebenza okuzenzekelayo ngokupheleleyo, kunye nemisebenzi efana nokujongwa koxinzelelo, i-alarm yempazamo, ukusetyenziswa kokusetyenziswa kwamandla, kunye nenkxaso yokubeka iliso kude.
Inkqubo iqhuba umjikelo we-adsorption-desorption ngotshintsho loxinzelelo. Xa kuthelekiswa nobuchwephesha bePSA bemveli, uncedo lwevacuum lunciphisa kakhulu ukusetyenziswa kwamandla (malunga ne-0.32-0.38kWh/Nm³). Isetyenziswe ngokubanzi kwintsimbi, iikhemikhali, unyango kunye nezinye iindawo, kwaye ifaneleke ngokukodwa kwiimeko zemfuno ye-oksijini ephakathi kunye nenkulu.
IQEMBU le-NUZHUO lizibophelele kuphando lwesicelo, ukuveliswa kwezixhobo kunye neenkonzo ezibanzi zemveliso yegesi yokwahlukana kobushushu obuqhelekileyo bomoya, ukubonelela ngamashishini aphezulu kunye nabasebenzisi bemveliso yerhasi yehlabathi kunye nezisombululo zegesi ezifanelekileyo nezibanzi zokuqinisekisa ukuba abathengi bafezekisa imveliso ebalaseleyo. Ukuba ufuna ukwazi iinkcukacha ezifanelekileyo okanye iimfuno, nceda uzive ukhululekile ukuqhagamshelana nathi
