Pressure swing adsorption nitrogen / oxygen kupanga mapangidwe
Mfundo Yogwirira Ntchito
Malinga ndi mfundo ya pressure swing adsorption, jenereta ya nayitrogeni imagwiritsa ntchito sieve yapamwamba kwambiri ya carbon molecular monga adsorbent kuti ichotse nayitrogeni mumlengalenga movutikira.Mpweya woyengedwa ndi wowuma woponderezedwa umadyedwa pansi pa kupanikizika ndikuphwanyidwa pansi pa kupsinjika kwafupipafupi mu adsorber.Chifukwa cha mphamvu ya aerodynamic, kuchuluka kwa okosijeni mu ma micropores a carbon molecular sieve ndikokwera kwambiri kuposa nayitrogeni.Oxygen imapangidwa makamaka ndi sieve ya carbon molecular sieve, ndipo nayitrogeni amawonjezeredwa mu gawo la mpweya kuti apange nayitrogeni womaliza.Kenako, pambuyo pa kutsika kwa mphamvu ya mumlengalenga, adsorbent imachotsa mpweya wa adsorbed ndi zonyansa zina kuti zizindikire kusinthika.Nthawi zambiri, nsanja ziwiri za adsorption zimayikidwa mu dongosolo.Nsanja imodzi imadsorbetsa nayitrogeni ndipo nsanja ina imadetsa ndikubwezeretsanso.Woyang'anira pulogalamu ya PLC amawongolera kutsegula ndi kutseka kwa valavu ya pneumatic kuti nsanja ziwiri zizizungulira mosinthana, kuti akwaniritse cholinga chopitiliza kupanga nayitrogeni wapamwamba kwambiri.
Kuyenda kwadongosolo
Dongosolo lonse lotulutsa mpweya wa okosijeni lili ndi zigawo izi:
Air compressor ➜ tank buffer ➜ compressed air purification device ➜ air process tank ➜ oxygen nitrogen separation device ➜ tank process oxygen.
1. Air kompresa
Monga gwero la mpweya ndi zida zamagetsi za jenereta ya nayitrogeni, kompresa ya mpweya nthawi zambiri imasankhidwa ngati makina opangira ma screw ndi centrifuge kuti ipereke mpweya wokwanira woponderezedwa kwa jenereta ya nayitrogeni kuonetsetsa kuti jenereta ya nayitrogeni ikugwira ntchito bwino.
2. Tanki yosungira
Ntchito za thanki yosungiramo ndi: kubisa, kukhazikika kwa kuthamanga ndi kuziziritsa;Kuti muchepetse kusinthasintha kwa kuthamanga kwa dongosolo, chotsani zonse zonyansa zamadzi amafuta kudzera pa valve yotsitsa pansi, pangani mpweya woponderezedwa kuti udutse bwino pagawo loyeretsera mpweya, ndikuwonetsetsa kuti zidazo zikugwira ntchito modalirika komanso mokhazikika.
3. Wopanikizika mpweya kuyeretsa chipangizo
Mpweya wopanikizidwa kuchokera ku tanki ya bafa umalowetsedwa koyamba mu chipangizo choyeretsera mpweya.Mafuta ambiri, madzi ndi fumbi zimachotsedwa ndi degreaser yapamwamba kwambiri, ndiyeno zimakhazikikanso ndi chowumitsira madzi kuti chichotse madzi, kuchotsa mafuta ndi kuchotsa fumbi ndi fyuluta yabwino, yomwe imatsatiridwa ndi kuyeretsedwa kwakukulu.Malinga ndi momwe amagwirira ntchito, kampani ya Hande idapanga mwapadera makina opukutira mpweya kuti apewe kulowa kwamafuta ndikupereka chitetezo chokwanira cha sieve yama cell.Module yokonzedwa bwino yoyeretsa mpweya imatsimikizira moyo wautumiki wa sieve ya carbon molecular.Mpweya woyera womwe umagwiritsidwa ntchito ndi gawoli ukhoza kugwiritsidwa ntchito ngati mpweya wa zida.
4. Tanki yopangira mpweya
Ntchito ya thanki yosungiramo mpweya ndikuchepetsa kugunda kwa mpweya ndi buffer;Kuti kuchepetsa kusinthasintha kwa dongosolo kuthamanga ndi kupanga wothinikizidwa mpweya bwino kudutsa wothinikizidwa mpweya kuyeretsedwa chigawo chimodzi, kuti kwathunthu kuchotsa zosafunika mafuta-madzi ndi kuchepetsa katundu wotsatira PSA asafe ndi mpweya kulekana unit.Pa nthawi yomweyi, pakusintha ntchito ya nsanja ya adsorption, imaperekanso PSA nayitrogeni ndi mpweya wolekanitsa wagawo ndi mpweya wambiri wothinikizidwa womwe ukufunika kuti uwonjezeke mwachangu pakanthawi kochepa, zomwe zimapangitsa kuthamanga kwa nsanja ya adsorption kukwera. kupanikizika kogwira ntchito mwamsanga, kuonetsetsa kuti ntchito yodalirika ndi yokhazikika ya zida.
5. Oxygen nitrogen separation unit
Pali nsanja ziwiri za adsorption a ndi B zokhala ndi sieve yapadera ya carbon molecular.Pamene mpweya woyera wothinikizidwa ulowa kumapeto kwa nsanja a ndikuyenda mpaka kumapeto kwa sieve ya carbon molecular, O2, CO2 ndi H2O amalowetsedwa ndi izo, ndipo nayitrogeni wa mankhwala amachokera kumapeto kwa nsanja ya adsorption.Patapita nthawi, kutsekemera kwa carbon molecular sieve mu nsanja a kumadzaza.Panthawiyi, nsanja ya a tower imangoyimitsa kutengera, mpweya woponderezedwa umalowa mu Tower B kuti ukamwe okosijeni ndi kupanga nayitrogeni, ndikupangitsanso sieve ya maselo a nsanja a.Kubwezeretsedwa kwa sieve ya maselo kumachitika pochepetsa mofulumira nsanja ya adsorption ku kuthamanga kwa mumlengalenga ndikuchotsa adsorbed O2, CO2 ndi H2O.Zinsanja ziwirizi zimapanga ma adsorption ndi kusinthika mosinthana kuti amalize kulekanitsa mpweya ndi nayitrogeni ndikutulutsa nayitrogeni mosalekeza.Njira zomwe zili pamwambazi zimayendetsedwa ndi programmable logic controller (PLC).Chiyero cha nayitrogeni pamalo opangira mafuta chikakhazikitsidwa, pulogalamu ya PLC idzatsegula valavu yotsegulira yokhayo kuti itulutse nayitrogeni wosayenerera, kudula nayitrogeni wosayenerera kuti asasunthike kupita kumalo ogwiritsira ntchito gasi, ndikugwiritsa ntchito silencer kuchepetsa phokoso lomwe lili pansipa. 78dba panthawi yotulutsa mpweya.
6. Nayitrojeni ndondomeko thanki
Tanki yosungiramo nayitrogeni imagwiritsidwa ntchito kulinganiza kuthamanga ndi kuyera kwa nayitrogeni wolekanitsidwa ndi njira yolekanitsa mpweya wa nayitrojeni kuti zitsimikizire kukhazikika kosalekeza kwa nayitrogeni.Panthawi imodzimodziyo, pambuyo posintha ntchito ya nsanja ya adsorption, imapanganso gawo la mpweya wake mu nsanja ya adsorption, yomwe imathandizira kukwera kwa nsanja ya adsorption, komanso imathandizira kuteteza bedi, ndi kusewera. njira yofunikira kwambiri yothandizira gawo lothandizira pakugwira ntchito kwa zida.
7. Zizindikiro zaumisiri
Kuthamanga: 5-3000nm ³ / h
Chiyero: 95% - 99.999%
Mame: ≤ - 40 ℃
Kupanikizika: ≤ 0.6MPa (zosinthika)
8.Mawonekedwe aukadaulo
1. Mpweya woponderezedwa uli ndi chipangizo choyeretsera mpweya ndi kuyanika.Mpweya waukhondo ndi wowuma umathandizira kukulitsa moyo wautumiki wa sieve ya maselo.
2. Valve yatsopano yoyimitsa pneumatic ili ndi liwiro lotsegula ndi kutseka, palibe kutayikira komanso moyo wautali wautumiki.Itha kukumana ndi kutsegula pafupipafupi komanso kutseka kwa njira yotsatsira ma swing ndipo imakhala yodalirika kwambiri.
3. Njira yabwino yoyendetsera kayendetsedwe kake, kugawa mpweya wofanana, ndi kuchepetsa kuthamanga kwa mpweya.Zigawo zamkati zomwe zimakhala ndi mphamvu zogwiritsira ntchito mphamvu komanso ndalama zogulira
4. Sieve ya molekyulu yokhala ndi mphamvu zambiri, yogwira ntchito kwambiri komanso yochepetsera mphamvu yogwiritsira ntchito mphamvu imasankhidwa, ndipo chipangizo chopanda nayitrogeni chosayenerera chimatsekedwa mwanzeru kuti chitsimikizire mtundu wa nayitrogeni wa mankhwalawa.
5. Zidazi zimakhala ndi machitidwe okhazikika, osavuta, okhazikika, odzipangira okha, osagwira ntchito komanso otsika mtengo pachaka.
6. Iwo utenga PLC ulamuliro, amene angathe kuzindikira zonse basi ntchito.Iwo akhoza okonzeka ndi nayitrogeni chipangizo, otaya, chiyero basi dongosolo malamulo ndi dongosolo lakutali.
5. Munda wofunsira
Makampani amagetsi: Kutetezedwa kwa nayitrogeni kwa semiconductor ndi zida zamagetsi zamagetsi.
Kutentha mankhwala: kuwala annealing, Kutentha zoteteza, ufa zitsulo makina, maginito sintering, etc.
Makampani azakudya: okhala ndi zosefera zosefera, atha kugwiritsidwa ntchito pakudzaza nayitrogeni, kusungirako mbewu, kusunga zipatso ndi ndiwo zamasamba mwatsopano, vinyo ndi kusunga.
Makampani Chemical: nayitrogeni chophimba, m'malo, kuyeretsa, kuthamanga kufala, mankhwala anachita yolimbikitsa, mankhwala CHIKWANGWANI kupanga chitetezo, etc.
Makampani amafuta amafuta ndi gasi: kuyenga mafuta, kudzaza mapaipi amadzi otengera makina otengera nayitrogeni, kuzindikira kutayikira kwa bokosi.Kupanga jakisoni wa nayitrogeni.
Makampani opanga mankhwala: nayitrogeni wodzazidwa ndi yosungirako mankhwala Chinese ndi Western, pneumatic kufala kwa asafe wodzazidwa ndi mankhwala zipangizo, etc.
Makampani opanga chingwe: gasi woteteza popanga chingwe cholumikizira.
Ena: mafakitale azitsulo, mafakitale a mphira, makampani opanga ndege, etc.
Kuyera, kutuluka ndi kupanikizika ndizokhazikika komanso zosinthika kuti zikwaniritse zosowa za makasitomala osiyanasiyana.
