Ngaba uyazi ukubaluleka kweshishini le-PSA generator yeoksijini?

I-PSA generator ye-oksijini isebenzisa i-zeolite i-molecular sieve njenge-adsorbent, kwaye isebenzisa umgaqo we-adsorption ye-pressure kunye ne-decompression desorption ukuze i-adsorb kwaye ikhulule i-oksijini emoyeni, ngaloo ndlela ihlula i-oksijini kwisixhobo esizenzekelayo.

Isiphumo sokuhlukana kwe-zeolite ye-molecular sieve kwi-O2 kunye ne-N2 isekelwe kumahluko omncinci kwi-diameter eguquguqukayo yeegesi ezimbini.Iimolekyuli ze-N2 zinesantya sokusasazwa ngokukhawuleza kwi-micropores ye-zeolite molecular sieve, kwaye ii-molecule ze-O2 zinezinga eliphantsi lokusabalalisa.Ngokunyuka okuqhubekayo kwenkqubo yoshishino, imfuno yentengiso yeejeneretha ze-oxygen ye-PSA iyaqhubeka nokukhula, kwaye izixhobo zidlala indima ebalulekileyo kwishishini lemizi-mveliso.

1. Ukutsha okutyetyiswe ngeoksijini

Umxholo we-oxygen emoyeni ngu ≤21%.Ukutshiswa kwepetroli kwiibhoyili zemizi-mveliso kunye neekhilni zamashishini nazo zisebenza phantsi kwesi siqulatho somoya.Ukuziqhelanisa kubonise ukuba xa isixa segesi kunye ne-oksijini etshiswe yibhoyili ifikelela ngaphezu kwe-25%, ukugcinwa kwamandla kunokufikelela kuma-20%;ixesha lokufudumeza ukuqalisa kwibhoyili lifutshane ngo-1/2-2/3.Ukutyetyiswa kwe-oksijeni kukusetyenziswa kweendlela eziphathekayo zokuqokelela i-oksijini emoyeni, ukwenzela ukuba umxholo wokutyebisa i-oksijini kwi-gas eqokelelweyo yi-25% -30%.

2. Intsimi yokwenza amaphepha

Ngokuphuculwa kwelizwe kwiimfuno zokhuseleko lokusingqongileyo kwiinkqubo zokwenziwa kwephepha, iimfuno zepulp emhlophe (kuquka i-pulp yeplanga, i-pulp yengcongolo, kunye ne-bamboo pulp) iye yanyuka ngokunyuka.Umgca wokuvelisa i-pulp ye-chlorine yokuqala kufuneka uguqulwe ngokuthe ngcembe ube ngumgca wokuvelisa i-pulp engena-chlorine;Umgca omtsha wokuvelisa i-pulp ufuna ukusetyenziswa kwenkqubo yokucoca i-chlorine-free, kwaye i-pulp bleaching ayifuni i-oksijeni ephezulu.Ioksijini eveliswa yi-pressure swing adsorption oxygen generator ihlangabezana neemfuno, ezinoqoqosho kunye nokusingqongileyo.

3. Intsimi yokunyibilikisa engeyiyo i-ferrous

Ngokuhlengahlengiswa kolwakhiwo lwelizwe loshishino, ukunyibilikiswa kwe-non-ferrous kuye kwaphuhliswa ngokukhawuleza kwiminyaka yakutshanje.Abavelisi abaninzi kwizinyibilikisi ezisebenzisa i-oksijini esezantsi evuthela ilothe, ikopolo, i-zinc, kunye neenkqubo zokunyibilikisa i-antimony kunye ne-oxygen leaching igolide kunye neenkqubo zokunyibilikisa i-nickel sele ziqalisile ukusebenzisa i-pressure swing adsorption generators.Imarike yokusetyenziswa kweejenereyitha ze-oksijini ye-PSA yandisiwe.

Umgangatho we-molecular sieve esetyenziswa kwi-PSA i-oxygen generator ithatha indawo enkulu.Iisefu zemolekyuli zingundoqo woxinzelelo lwe-swing adsorption.Ukusebenza okuphezulu kunye nobomi benkonzo ye-molecular sieves inefuthe elithe ngqo ekuzinzeni kwesivuno kunye nokucoceka.
