Shin kun san mahimmancin masana'antu na PSA janareta na oxygen?

PSA oxygen janareta yana amfani da zeolite kwayoyin sieve a matsayin adsorbent, kuma yana amfani da ka'idar matsa lamba adsorption da decompression desorption to adsorb da saki oxygen daga iska, game da shi raba oxygen daga atomatik kayan aiki.

Sakamakon rabuwa na zeolite kwayoyin sieve akan O2 da N2 ya dogara ne akan ƙaramin bambanci a cikin diamita mai ƙarfi na gas biyu.N2 kwayoyin suna da saurin yaduwa a cikin micropores na zeolite molecular sieve, kuma kwayoyin O2 suna da saurin yaduwa.Tare da ci gaba da haɓaka tsarin masana'antu, buƙatun kasuwa na masu samar da iskar oxygen na PSA yana ci gaba da ƙaruwa, kuma kayan aiki suna taka muhimmiyar rawa a cikin masana'antar masana'antu.

1. Konewa mai wadataccen iskar oxygen

Abun oxygen a cikin iska shine ≤21%.Konewar mai a cikin tukunyar jirgi na masana'antu da kiln masana'antu shima yana aiki ƙarƙashin wannan abun cikin iska.Aiki ya nuna cewa lokacin da adadin iskar gas da oxygen kona ta tukunyar jirgi ya kai fiye da 25%, ceton makamashi zai iya kaiwa 20%;lokacin dumama tukunyar tukunyar jirgi yana raguwa da 1/2-2/3.Isar da iskar oxygen shine aikace-aikacen hanyoyin jiki don tattara iskar oxygen a cikin iska, don haka abun cikin iskar oxygen a cikin iskar da aka tattara shine 25% -30%.

2. Filin yin takarda

Tare da haɓaka buƙatun kare muhalli na ƙasar don aiwatar da takaddun takarda, buƙatun farar ɓangaren litattafan almara (ciki har da ɓangaren itace, ɓangaren reed, da ɓangarorin bamboo) sun zama mafi girma kuma mafi girma.Asalin layin samar da ɓangaren litattafan almara na chlorine ya kamata a canza shi sannu a hankali zuwa layin samar da ɓangaren litattafan almara mara chlorine;Sabon layin samar da ɓangaren litattafan almara yana buƙatar amfani da tsarin bleaching mara chlorine, kuma bleaching ɗin ɓangaren litattafan almara baya buƙatar iskar oxygen mai tsafta.Oxygen da aka samar ta hanyar matsa lamba swing adsorption iskar oxygen janareta ya dace da buƙatun, wanda ke da alaƙa da tattalin arziki da muhalli.

3. Filin narkawa mara ƙarfe

Tare da daidaitawa na tsarin masana'antu na kasa, ba da ferrous narke ya ci gaba da sauri a cikin 'yan shekarun nan.Yawancin masana'antun a cikin masana'antun da ke amfani da iskar oxygen na busa gubar, jan ƙarfe, zinc, da tsarin narkewar antimony da oxygen leaching zinariya da nickel tafiyar matakai na narkewa sun fara amfani da matsa lamba adsorption adsorption oxygen janareto.An faɗaɗa kasuwar amfani da iskar oxygen ta PSA.

Ingancin sieve kwayoyin da ake amfani da su a cikin janareta na oxygen na PSA ya mamaye babban matsayi.Sives na kwayoyin halitta sune tushen tallan jujjuyawar matsa lamba.Mafi kyawun aiki da rayuwar sabis na sieves na ƙwayoyin cuta suna da tasiri kai tsaye akan kwanciyar hankali na yawan amfanin ƙasa da tsabta.
