VPSAO vakuyumu kuthamanga kugwedezeka adsorption mpweya kupanga zida
Mfundo yogwira ntchito
Zigawo zazikulu mu mlengalenga ndi nayitrogeni ndi mpweya, ntchito yozungulira kutentha, nayitrogeni ndi mpweya mu mpweya zeolite molecular sieve (ZMS) adsorption ntchito ndi osiyana (oxygen akhoza kudutsa ndi nayitrogeni adsorption), kupanga njira yoyenera, ndi kupanga nayitrogeni. ndi kupatukana kwa okosijeni kuti mupeze oxygen.Nayitrojeni pa zeolite molecular sieve adsorption mphamvu ndi yabwino kuposa mpweya (nitrogen ion ndi molecular sieve pamwamba mphamvu yamphamvu), pamene kuthamanga kwa mpweya mu dziko ndi zeolite molecular sieve adsorbent adsorption bedi, nayitrogeni ndi molecular sieve adsorption , mpweya wocheperako potengera, ndende komanso kuyenda kwa bedi la gasi, kupatukana kwa okosijeni ndi nayitrogeni kwa okosijeni. maselo sieve kusinthika ndipo akhoza reused.When awiri kapena kuposa mabedi adsorption kusinthana ntchito nayenso, mpweya akhoza mosalekeza kupangidwa.
Oxygen ndi nayitrogeni ali ndi mfundo zowira zofanana, zomwe zimapangitsa kuti zikhale zovuta kuzilekanitsa, ndipo zimalemeretsedwa pamodzi mumlengalenga.Choncho, zipangizo zopangira mpweya wa psa nthawi zambiri zimangopeza 90-95% ya okosijeni (oksijeni woipa kwambiri ndi 95.6%, ena onse. ndi argon), yomwe imadziwikanso kuti oxygen rich.Poyerekeza ndi mayunitsi olekanitsa mpweya wa cryogenic, omalizawa amatha kutulutsa mpweya woposa 99.5%.
Chipangizo ndondomeko
Bedi la adsorption la psa air separation oxygen plant liyenera kukhala ndi masitepe awiri ogwiritsira ntchito.Adsorption ndi resolution.Kuti mupitirize kupeza mpweya wamagetsi, nthawi zambiri mabedi oposa awiri amaikidwa mu chipangizo chopangira mpweya, komanso kuchokera ku mphamvu yogwiritsira ntchito mphamvu ndi mphamvu. Kukhazikika, masitepe ofunikira othandizira amakhazikitsidwa. Bedi lililonse la adsorption nthawi zambiri limayenera kutsatiridwa, kutulutsidwa kwamphamvu, kuthamangitsidwa kapena kutsitsimukanso, kusinthana m'malo ndi masitepe owonjezera amphamvu, opareshoni yobwerezabwereza nthawi ndi nthawi. masitepe osiyana ntchito, pansi pa ulamuliro wa PLC nthawi lophimba, kuti angapo adsorption bedi kugwirizanitsa ntchito, mchitidwe ndi staggered wina ndi mzake, kuti kuthamanga kugwedezeka adsorption chipangizo akhoza kuthamanga bwino, mosalekeza kupeza mankhwala gas.Other kufufuza zigawo mu mlengalenga. ziyenera kuganiziridwanso pa ndondomeko yeniyeni yolekanitsa.Carbon dioxide ndi madzi mu mphamvu yachizolowezi ya adsorbent adsorbent nthawi zambiri imakhala yokulirapo kuposa nayitrogeni ndi mpweya, imatha kudzazidwa pabedi la adsorption ndi adsorbent yoyenera (kapena kugwiritsa ntchito okosijeni adsorbent yokha) kuti ipange adsorption ndi kuchotsa.
Kuchuluka kwa nsanja za adsorption zomwe zimafunidwa ndi chipangizo chopangira okosijeni zimatengera kukula kwa okosijeni, machitidwe a adsorbent ndi malingaliro opangira.Kukhazikika kwa magwiridwe antchito a nsanja zambiri ndikwabwinoko, koma ndalama zogulira zida ndizokwera kwambiri.Mchitidwe wapano ndikugwiritsa ntchito ma sorbents apamwamba kwambiri a okosijeni kuti achepetse kuchuluka kwa nsanja za adsorption ndikugwiritsa ntchito njira zazifupi zogwirira ntchito kuti ziwonjezeke bwino komanso kuchepetsa ndalama. .
Makhalidwe aukadaulo
1. Njira yosavuta yoyendera chipangizocho
2. Sikelo yopanga okosijeni pansi pa 10000m3/h, kugwiritsa ntchito mphamvu zopangira okosijeni ndikotsika, ndalama zochepa;
3 kuchuluka kwa zomangamanga ndi zazing'ono, unsembe mkombero wa chipangizo ndi wamfupi kuposa chipangizo cryogenic;
4. Mtengo wotsika wa ntchito ndi kukonza chipangizo;
5. mkulu mlingo wa zochita zokha za chipangizo ntchito, yabwino ndi mwamsanga kuyamba ndi kuyimitsa, opareshoni ochepa;
6. ntchito ya chipangizocho ndi yokhazikika komanso yotetezeka;
7. ntchitoyo ndi yosavuta, zigawo zikuluzikulu zimasankhidwa opanga odziwika padziko lonse;
8. kugwiritsa ntchito sieve ya oxygen yochokera kunja, magwiridwe antchito apamwamba komanso moyo wautali wautumiki;
9. kusinthasintha kwamphamvu kwa ntchito (mzere wapamwamba kwambiri, liwiro lotembenuka mwachangu).
