Jenereta wa okosijeni wa Plateau - jenereta wa oxygen

Kufotokozera Kwachidule:

Pressure swing adsorption oxygen jenereta ndi chida chodziwikiratu chomwe chimagwiritsa ntchito zeolite molekyulu sieve ngati adsorbent ndipo amagwiritsa ntchito mfundo ya kuthamanga kwa adsorption, kuchepetsa kupanikizika ndi desorption kuti adsorb ndi kutulutsa mpweya kuchokera mlengalenga, kuti alekanitse mpweya.Zeolite ndi mtundu wazinthu zaporous adsorption zokonzedwa ndiukadaulo wapadera.Pamwamba ndi mkati mwake zimakutidwa ndi ma microporous spherical granular adsorbent, omwe ndi achikasu chowala.Maonekedwe ake a pore amamuthandiza kuzindikira kupatukana kwa mpweya ndi nayitrogeni.Kulekanitsa kwa zeolite molekyulu sieve pa okosijeni ndi nayitrogeni kutengera kusiyana pang'ono kwa kinetic diameter ya mipweya iwiriyi.

Mamolekyu a nayitrogeni amakhala ndi kufalikira kwachangu mu ma micropores a zeolite molekyulu sieve, ndipo mamolekyu a okosijeni amakhala ndi kufalikira pang'onopang'ono.Kufalikira kwa madzi ndi mpweya woipa wa carbon dioxide mu mpweya wopanikizidwa ndi kofanana ndi kwa nayitrogeni.Pomaliza, mamolekyu okosijeni amalemeretsedwa kuchokera ku nsanja ya adsorption.Pressure swing adsorption adsorption oxygenation imagwiritsa ntchito mawonekedwe osankhidwa a zeolite molecular sieve, imatenga kuzungulira kwa kutengeka kwamphamvu komanso kutsika kwapang'onopang'ono, ndikupanga mpweya woponderezedwa kulowa munsanja ya adsorption mosinthana kuti izindikire kulekanitsidwa kwa oxygen ndi nayitrogeni, kuti mosalekeza kutulutsa mpweya wambiri. - chiyero ndi mpweya wabwino kwambiri.

Jenereta ya okosijeni ya PSA imatenga zeolite yapamwamba kwambiri ngati adsorbent molingana ndi mfundo ya kuthamanga kwa adsorption.Pansi pa kupanikizika kwina, mpweya umachotsedwa mumlengalenga, woyeretsedwa ndi wowumitsidwa mpweya, ndipo kutengeka kwapanikizidwe ndi decompression desorption kumachitika mu adsorber.Chifukwa cha mphamvu ya aerodynamic, kufalikira kwa nayitrogeni mu ma micropores a zeolite molekyulu sieve ndikokwera kwambiri kuposa mpweya.Nayitrojeni amalowetsedwa ndi zeolite molekyulu sieve, ndipo mpweya umalemeretsedwa mu gawo la mpweya kuti apange mpweya womaliza.Ndiye, pambuyo decompression kwa mpweya kuthamanga, maselo sieve desorbed nayitrogeni ndi zonyansa zina kuzindikira kusinthika.Nthawi zambiri, nsanja ziwiri za adsorption zimayikidwa mu dongosolo, imodzi ya adsorption ndi kupanga mpweya, ndipo ina ya desorption ndi kusinthika.Woyang'anira pulogalamu ya PLC amawongolera kutsegula ndi kutseka kwa valve ya pneumatic kuti nsanja ziwiri zizizungulira mosiyanasiyana, kuti akwaniritse cholinga chopitiriza kupanga mpweya wabwino kwambiri.
