The ntchito mfundo vakuyumu kuthamanga kugwedezeka adsorption mpweya Plant (VPSA O2 Chomera) ndi ntchito lifiyamu maselo sieve kusankha adsorb nayitrogeni mu mlengalenga, kuti mpweya wolemera pamwamba pa nsanja adsorption monga mankhwala linanena bungwe mpweya. Njira yonseyi imaphatikizapo masitepe awiri a adsorption (kutsika kochepa) ndi desorption (vacuum, ndiko kuti, kupanikizika koipa), ndipo ntchitoyi imabwerezedwa mozungulira. Kuti mosalekeza kupeza mankhwala okosijeni, dongosolo adsorption wa VPSA mpweya wagawo kupanga wapangidwa ndi nsanja ziwiri adsorption okonzeka ndi maselo sieve (ndikuganiza nsanja A ndi nsanja B) ndi payipi ndi mavavu.
Mpweya woponderezedwa umasefedwa ndikulowa mu nsanja A, ndiye mpweyawo umasonkhanitsidwa pamwamba pa nsanja ya adsorption A monga kutulutsa kwa gasi. Pa nthawi yomweyo, Tower B ali mu siteji kusinthika, pamene nsanja A ali mu ndondomeko adsorption amakonda adsorption machulukitsidwe, pansi pa ulamuliro wa kompyuta, mpweya gwero akutembenukira ku Tower B ndi kulowa adsorption mpweya kupanga ndondomeko. Zinsanja ziwirizi zimagwirizana pozungulira kuti akwaniritse kupanga mpweya wokwanira.

(1) VPSA O2 Chomera Adsorption Njira
Pambuyo polimbikitsidwa ndi chowombera mizu, mpweya wodyetsa udzatumizidwa mwachindunji kwa adsorber momwe zigawo zosiyanasiyana (mwachitsanzo H.2O, CO2ndi N2) adzalowetsedwa motsatizana ndi ma adsorbents angapo kuti apitirize kupeza O2(kuyera kumatha kusinthidwa kudzera pakompyuta pakati pa 70% ndi 93%). O2zidzatulutsidwa kuchokera pamwamba pa adsorber, ndiyeno zidzaperekedwa mu thanki yosungiramo zinthu.
Malinga ndi zomwe makasitomala amafuna, mitundu yosiyanasiyana ya ma compressor okosijeni atha kugwiritsidwa ntchito kukakamiza mpweya wocheperako kuti ufikire kukakamiza komwe mukufuna.
Pamene m'mphepete kutsogolo (kutchedwa adsorption kutsogolera m'mphepete) kwa malo osamutsira misa ya zonyansa zomwe zakhala zikufika pamalo enaake pamalo osungiramo bedi, valavu yolowera mpweya ndi valavu yotulutsa mpweya wa adsorber idzatsekedwa. kusiya kuyamwa. Bedi la adsorbent limayamba kusinthira ku kuchira kofanana ndi kukonzanso.
(2)VPSA O2 Plant Equal-Depressurize Process
Imeneyi ndi njira yomwe, ikatsirizika kwa njira yotsatsira, mpweya wochuluka wa okosijeni wowonjezera mpweya mu absorber umayikidwa mu vacuum pressure adsorber ndi kubadwanso kumatsirizidwa mu njira yomweyo ya adsorption Iyi si njira yochepetsera kuthamanga koma komanso njira yotsitsimula mpweya kuchokera kumalo akufa a bedi. Chifukwa chake, mpweya ukhoza kubwezeretsedwanso bwino, kuti uwongolere kuchuluka kwa mpweya.
(3) VPSA O2 Plant Vacuumizing Njira
Pambuyo pomaliza kufananiza kuthamanga, pakukonzanso kwakukulu kwa adsorbent, bedi la adsorption litha kutulutsidwa ndi pampu ya vacuum mbali imodzi ya adsorption, kuti muchepetse kupanikizika pang'ono kwa zonyansa, kuwononga kwathunthu zonyansa za adsorbed, ndikusinthanso kwambiri. adsorbent.
(4) VPSA O2 Plant Equal- Repressurize Process
Pambuyo pomaliza kupukuta ndi kukonzanso, adsorber idzakulitsidwa ndi mpweya wowonjezera wa okosijeni wochuluka kuchokera ku zotsatsa zina. Njirayi ikugwirizana ndi kukakamiza kufananitsa ndi kuchepetsa ndondomeko, zomwe sizingowonjezera njira yowonjezera komanso njira yochepetsera mpweya kuchokera kumalo akufa a adsorbers ena.
(5) VPSA O2 Chomera Final Product Gasi Repressurizing Njira
Pambuyo pa Equal-depressurize process, kuwonetsetsa kusinthika kokhazikika kwa adsorber kupita kumayendedwe otsatirawa, kutsimikizira chiyero cha mankhwala, ndikuchepetsa kusinthasintha kwanjira iyi, ndikofunikira kukulitsa kukakamiza kwa adsorber kukakamiza mayamwidwe ndi mankhwala okosijeni.
Pambuyo pa ndondomeko yomwe ili pamwambayi, kuzungulira kwa "mayamwidwe - kusinthika" kumatsirizidwa mu adsorber, yomwe ili yokonzekera ulendo wotsatira wa kuyamwa.
Ma adsorbers awiriwa azigwira ntchito mwanjira ina motsatira njira zina, kuti athe kuzindikira kupatukana kwa mpweya kosalekeza ndikupeza okosijeni wazinthu.
