Kodi mukudziwa tanthauzo la mafakitale la PSA oxygen generator?

PSA mpweya jenereta amagwiritsa zeolite molekyulu sieve monga adsorbent, ndipo amagwiritsa ntchito mfundo ya kuthamanga adsorption ndi decompression desorption kuti adsorb ndi kumasula mpweya mlengalenga, motero kulekanitsa mpweya ku zipangizo basi.

Kupatukana kwa zeolite molekyulu sieve pa O2 ndi N2 kutengera kusiyana kwakung'ono kwa kukula kwa mipweya iwiriyi.Mamolekyu a N2 amakhala ndi kufalikira kwachangu mu ma micropores a zeolite molekyulu sieve, ndipo mamolekyu a O2 amakhala ndi kufalikira pang'onopang'ono.Ndikuchulukirachulukira kwanthawi yayitali kwamakampani, kufunikira kwa msika wamajenereta okosijeni a PSA kukukulirakulira, ndipo zida zimagwira ntchito yofunika kwambiri pamafakitale.

1. Kuwotcha kwa okosijeni

Mpweya wa okosijeni mumlengalenga ndi ≤21%.Kuwotcha kwamafuta m'ma boiler a mafakitale ndi ma kilns a mafakitale kumagwiranso ntchito pansi pa mpweya uwu.Zochita zasonyeza kuti pamene kuchuluka kwa mpweya ndi mpweya wotenthedwa ndi chowotchera kufika kupitirira 25%, kupulumutsa mphamvu kumatha kufika 20%;Kutentha kwa boiler yoyambira kumafupikitsidwa ndi 1/2-2/3.Kuchuluka kwa okosijeni ndikugwiritsa ntchito njira zakuthupi kutengera mpweya mumlengalenga, kotero kuti zopatsa mpweya zomwe zili mu gasi wosonkhanitsidwa ndi 25% -30%.

2. Kupanga mapepala

Ndi kukwezedwa kwa dziko kwa malamulo oteteza chilengedwe popanga mapepala, zofunikira pazamkati zoyera (kuphatikiza zamkati zamatabwa, zamkati za bango, ndi nsungwi) zakwera kwambiri.Mzere woyamba wa klorini wowukitsidwa wa zamkati uyenera kusinthidwa pang'onopang'ono kukhala mzere wopangira zamkati wopanda chlorine;Mzere watsopano wopangira zamkati umafunikira kugwiritsa ntchito njira yothira madzi opanda chlorine, ndipo kuthirira kwa zamkati sikufuna mpweya wabwino kwambiri.Mpweya wopangidwa ndi jenereta ya okosijeni wa adsorption oxygen umakwaniritsa zofunikira, zomwe ndi zachuma komanso zachilengedwe.

3. Malo osungunula opanda chitsulo

Ndi kusintha kwa mafakitale a dziko lonse, smelting yopanda chitsulo yakhala ikukula mofulumira m'zaka zaposachedwa.Ambiri opanga ma smelters omwe amagwiritsa ntchito mpweya wotulutsa mpweya pansi, mkuwa, zinki, ndi njira zosungunulira za antimoni ndi njira zosungunulira za golide ndi faifi wa okosijeni ayamba kugwiritsa ntchito majenereta a okosijeni.Msika wogwiritsa ntchito ma jenereta okosijeni a PSA wawonjezedwa.

Ubwino wa sieve yama cell omwe amagwiritsidwa ntchito mu PSA oxygen jenereta amakhala ndi udindo waukulu.Masieve a mamolekyulu ndiye maziko a kuthamangitsidwa kwa swing adsorption.Kuchita kwapamwamba ndi moyo wautumiki wa masieve a maselo amakhudza mwachindunji kukhazikika kwa zokolola ndi chiyero.
