Kusiyana pakati VPSA mpweya jenereta ndi PSA mpweya jenereta

Kukwera bwino, VPSA (low pressure adsorption vacuum desorption) kupanga mpweya ndi "mitundu" ina yaKupanga kwa oxygen kwa PSA, mfundo yawo yopanga okosijeni imakhala yofanana, ndipo kusakaniza kwa gasi kumasiyanitsidwa ndi kusiyana kwa mphamvu ya sieve ya maselo kuti "adsorb" mamolekyu osiyanasiyana a gasi.Koma njira yopangira mpweya wa PSA ndi kudzera pa Pressurize adsorption, kutsika kwamphamvu kwamlengalenga kuti mulekanitse mpweya.The VPSA ndondomeko kupanga mpweya ndi desorption zimalimbikitsa maselo sieve pansi zingalowe zinthu.

Ngakhale kuti zonsezi zimachokera ku mpweya ngati zipangizo, mfundo yopangira mpweya ndi yofanana.Koma poyerekezera mosamalitsa, pali kusiyana kotere;

1. TheVPSA mpweya jeneretaamagwiritsa ntchito chowombera kuti apeze mpweya wosaphika ndikuupanikiza, pomwe jenereta ya okosijeni ya PSA imagwiritsa ntchito kompresa ya mpweya kuti ipereke mpweya.

2, Pachimake chigawo - zeolite maselo sieve kusankha, PSA mpweya jenereta amagwiritsa sodium maselo sieve ndi VPSA mpweya jenereta amagwiritsa lithiamu maselo sieve.

3. Kuthamanga kwa adsorption kwa PSA mpweya jenereta kawirikawiri 0.6 ~ 0.8Mpa, ndi adsorption kuthamanga VPSA mpweya jenereta ndi 0.05Mpa ndi kuthamanga desorption ndi -0.05Mpa.

4, PSA limodzi chomera mpweya mphamvu kupanga akhoza kufika 200 ~ 300Nm³/h, ndi VPSA limodzi chomera mpweya mphamvu kupanga akhoza kufika 7500 ~ 9000Nm³/h.

5, VPSA wachibale PSA, ndi otsika mphamvu mowa (kupanga 1Nm3 mpweya mphamvu mowa ≤ 0.31kW, mpweya chiyero 90%, popanda psinjika mpweya), ndi zambiri zachilengedwe.

6, Malinga ndi kupanga okosijeni, miyezo yogwiritsira ntchito mphamvu ndi ndalama pakusankha njira ya PSA kapena njira ya VPSA.

VPSA mpweya jenereta ngakhale limodzi chomera mpweya mphamvu kupanga lalikulu, koma akusowa ndi kuti zipangizo dongosolo ndi zovuta, buku la zida ndi lalikulu (poyerekeza ndi chipangizo cryogenic akadali ang'onoang'ono), kuthandiza ndi zofunikira zinthu zofunika kwambiri. , itenga malo okulirapo, nthawi zambiri sangapangidwe kukhala chidebe.Ndipo ikufunika kuyika pamalowo, kuyitanitsa, kuyambira pano kokha.PSA ili ndi zabwino zina.
