Zida zopangira mpweya wa VPSA

①: Chiyambi cha zida ndi mfundo zogwirira ntchito
VPSA (Vacuum Pressure Swing Adsorption) chipangizo chopanga okosijeni, Chitchaina chotchedwa low pressure adsorption vacuum desorption oxygen kupanga zida.Pansi pa kupsinjika kwapansi, nayitrogeni ndi okosijeni mumlengalenga zimayamwa. Pambuyo pakukhutitsidwa kwa adsorption, sieve ya molekyulu imaphwanyidwa pansi pa vacuum mikhalidwe, ndipo nayitrogeni amachotsedwa padoko lotayira.Mpweya umalowa m'dongosolo loyeretsa.Sieve ya molekyulu imatulutsidwa mosalekeza ndikuphwanyidwa kuti izungulira kuti ipange mpweya wabwino kwambiri (90-95%).
③: Kupanga zida ndi zizindikiro zaukadaulo
VPSA zida mpweya kupanga makamaka wapangidwa ndi blower, vacuum mpope, ozizira, dongosolo adsorption, mpweya chotchinga thanki, ndi dongosolo kulamulira.
Zizindikiro zaukadaulo ndi izi:
◆ Mulingo wazinthu: 100-10000Nm3/h
◆ Kuyera kwa oxygen: ≥90-94%, ikhoza kusinthidwa mumtundu wa 30-95% malinga ndi zofunikira za wogwiritsa ntchito.
◆ Kugwiritsira ntchito mphamvu ya okosijeni: pamene kuyera kwa okosijeni ndi 90%, mphamvu yogwiritsira ntchito mphamvu yosinthidwa kukhala mpweya wabwino ndi 0.32-0.37KWh/ Nm3
◆ Kuthamanga kwa okosijeni: ≤20kpa (akhoza kupanikizidwa)

◆ Mphamvu yotsegulira pachaka: ≥95%

Zida zopangira mpweya wa PSA

①: Chiyambi cha zida ndi mfundo zogwirira ntchito
PSA (Pressure Swing mayamwidwe) mpweya m'badwo chipangizo, Chinese dzina ndi kuthamanga swing adsorption mpweya m'badwo.Mfundoyi ndikulekanitsa kusakaniza kwa gasi pogwiritsa ntchito kusiyana kwa "adsorption" ya sieve ya maselo ku mamolekyu osiyanasiyana a gasi.Imagwiritsa ntchito mpweya ngati zopangira, ndipo imagwiritsa ntchito mphamvu yapamwamba, yosankha bwino kwambiri kuti iwononge nayitrogeni ndi mpweya kuti ilekanitse nayitrogeni ndi mpweya mumlengalenga.Pansi pa kutentha ndi kupanikizika, PSA yapadera ya molecular sieve imagwiritsidwa ntchito posankha zonyansa monga nitrogen, carbon dioxide ndi madzi mumlengalenga kuti apeze mpweya wabwino kwambiri.
③: Kupanga zida ndi zizindikiro zaukadaulo
Zida zopangira mpweya wa PSA zimapangidwa makamaka ndi kompresa mpweya, chowumitsira firiji, deoiler, adsorption system, tanki ya oxygen buffer, ndi dongosolo lowongolera.
Zizindikiro zaukadaulo ndi izi↓↓
Chiyero: 93% + 2% (93% ya mtundu wamba)
Kupanikizika: ≥0.2Mpa
Mame point: <-40 ℃ (kupanikizika wamba)
Kutulutsa: 3 ~ 200Nm3/h
