Pressure Swing Adsorption e sebetsa joang?
Ha u iketsetsa nitrogen ea hau, ho bohlokoa ho tseba le ho utloisisa boemo ba bohloeki boo u batlang ho bo fihlela.Likopo tse ling li hloka maemo a tlase a bohloeki (pakeng tsa 90 le 99%), joalo ka theko ea lithaere le thibelo ea mollo, athe tse ling, joalo ka likopo tsa indasteri ea lijo le lino kapa ho bopa polasetiki, li hloka maemo a holimo (ho tloha ho 97 ho isa ho 99.999%).Maemong ana theknoloji ea PSA ke tsela e nepahetseng le e bonolo ka ho fetisisa ea ho tsamaea.
Ha e le hantle jenereithara ea naetrojene e sebetsa ka ho arola limolek'hule tsa naetrojene ho limolek'hule tsa oksijene ka har'a moea o hatelitsoeng.Pressure Swing Adsorption e etsa sena ka ho hula oksijene ho tsoa moeeng o hatelitsoeng ka ho sebelisa adsorption.Adsorption e etsahala ha limolek'hule li itlama ho adsorbent, tabeng ena limolek'hule tsa oksijene li hokela ho sieve ea carbon molecular (CMS).Sena se etsahala ka likepe tse peli tse arohaneng tsa khatello, e 'ngoe le e' ngoe e tletse CMS, e fetohang pakeng tsa ts'ebetso ea karohano le ts'ebetso ea ho nchafatsa.Hajoale, a re ba bitseng tora A le tora ea B.
Ha u qala, moea o hatelitsoeng o hloekileng le o omileng o kena tora ea A 'me kaha limolek'hule tsa oksijene li nyane ho feta limolek'hule tsa naetrojene, li tla kena masobeng a sieve ea carbon.Ka lehlakoreng le leng, limolek'hule tsa naetrojene ha li khone ho kena ka har'a li-pores kahoo li tla qoba sieve ea carbon molecular.Ka lebaka leo, u qetella u e-na le naetrojene ea bohloeki bo lakatsehang.Karolo ena e bitsoa adsorption kapa karohano.
Leha ho le joalo, ha e felle moo.Bongata ba naetrojene e hlahisoang tora ea A e tsoa ka har'a sistimi (e loketse ho sebelisoa kapa ho bolokoa ka kotloloho), ha karolo e nyane ea naetrojene e hlahisoang e fofela tora ea B ka lehlakoreng le fapaneng (ho tloha holimo ho ea tlase).Phallo ena e hlokeha ho sutumelletsa oksijene e neng e hapiloe karolong e fetileng ea adsorption ea tora ea B. Ka ho lokolla khatello ea tora ea B, li-sieve tsa carbon molecular li lahleheloa ke matla a tsona a ho tšoara limolek'hule tsa oksijene.Li tla ikhula ka har'a li-sieve 'me li tlosoe ka mokelikeli ke phallo e nyenyane ea naetrojene e tsoang tora ea A. Ka ho etsa joalo tsamaiso e etsa sebaka sa hore limolek'hule tse ncha tsa oksijene li khomarele li-sieve mokhahlelong o latelang oa adsorption.Re bitsa ts'ebetso ena ea ho 'hloekisa' ho nchafatsa tora e tletseng oksijene.
Taba ea pele, tanka A e mokhahlelong oa adsorption ha tanka ea B e ntse e nchafala.Mokhahlelong oa bobeli lijana ka bobeli li lekana khatello ea ho itokisetsa switjha.Kamora ho chencha, tanka A e qala ho inchafatsa ha tanka ea B e hlahisa naetrojene.
Nakong ena, khatello ea litora ka bobeli e tla lekana 'me e tla fetola mekhahlelo ho tloha ho adsorbing ho ea ho tsosolosoa le ka tsela e fapaneng.CMS e tora ea A e tla tlala, ha tora ea B, ka lebaka la khatello ea maikutlo, e tla khona ho qala ts'ebetso ea adsorption hape.Ts'ebetso ena e boetse e bitsoa 'swing of pressure' , e bolelang hore e lumella hore likhase tse itseng li tšoaroe ka khatello e phahameng 'me li lokolloe ka khatello e tlaase.Sistimi ea tora e 'meli ea PSA e lumella tlhahiso e tsoelang pele ea naetrojene boemong bo lakatsehang ba tlhoeko.
