Ukomiswa komoya ocindezelwe
Ngokucindezela ngaphezulu
Ukucindezela ngokweqile kuyindlela elula yokomisa umoya ocindezelweyo.
Eyokuqala ukuthi umoya ucindezelwa ukucindezela okuphezulu kunokucindezela okulindelekile kokusebenza, okusho ukuthi ukuminyana komhwamuko wamanzi kuyanda.Ngemva kwalokho, umoya uyaphola futhi umswakama uyajiya uhlukane.Ekugcineni, umoya unwebeka ekucindezelweni kokusebenza, ufinyelele ku-PDP ephansi.Kodwa-ke, ngenxa yokusetshenziswa kwayo okuphezulu kwamandla, le ndlela ifaneleka kuphela ukuhamba komoya okuncane kakhulu.
Gcoba owomile
Ukomisa ukumuncwa kuyinqubo yamakhemikhali lapho kudonswa khona umhwamuko wamanzi.Izinto ezimuncwayo zingaba ziqinile noma zibe uketshezi.I-sodium chloride ne-sulfuric acid zivame ukusetshenziswa ama-desiccants futhi kungenzeka ukugqwala kufanele kucatshangelwe.Lezi zindlela azivamile ukusetshenziswa ngoba izinto ezimuncayo ezisetshenziswayo ziyabiza futhi indawo yamazolo yehliswa kuphela.
ukomiswa kwe-adsorption
Umgomo ojwayelekile wokusebenza kwesomisi ulula: lapho umoya omanzi ugeleza ngezinto ze-hygroscopic (imvamisa i-silica gel, ama-molecular sieves, i-alumina ecushiwe), umswakama emoyeni uyakhangiswa, ngakho-ke umoya uyomiswa.
Umhwamuko wamanzi udluliswa usuka emoyeni ocindezelwe onomswakama uye ku-hygroscopic material noma “adsorbent”, okuthi kancane kancane igcwale amanzi.Ngakho-ke, i-adsorbent kufanele ivuselelwe ngezikhathi ezithile ukuze ibuyisele amandla ayo okomisa, ngakho umshini wokomisa uvame ukuba neziqukathi ezimbili zokomisa: isitsha sokuqala somisa umoya ongenayo kuyilapho okwesibili kuvuselelwa.Lapho esinye sezitsha (“umbhoshongo”) sesiphelile, esinye sivuselelwa ngokugcwele.I-PDP efinyelelekayo ngokuvamile ingu -40°C, futhi lezi zomisi zinganikeza umoya owomile owanele ukuze kube nezinhlelo eziqinile.
Isomisi sokuvuselela ukusetshenziswa komoya (esaziwa nangokuthi “isomisi sokuvuselela esingenakushisa”)
Kunezindlela ezi-4 ezihlukene zokuvuselelwa kabusha kwe-desiccant, futhi indlela esetshenzisiwe inquma uhlobo lwesomisi.Izinhlobo ezonga amandla amaningi ngokuvamile ziyinkimbinkimbi futhi, ngakho-ke, zibiza kakhulu.

1. Isomisi sokushintsha i-pressure swing adsorption (esibizwa nangokuthi “isomisi sokuvuselela esingenakushisa”).Le mishini yokomisa ifaneleka kakhulu ekugelezeni komoya okuncane.Ukugcwaliseka kwenqubo yokuvuselela kudinga usizo lomoya ocindezelwe owandisiwe.Lapho ingcindezi yokusebenza ingu-7 bar, isomisi sisebenzisa u-15-20% wevolumu yomoya olinganisiwe.
2. Isomisi sokuvuselela ukushisisa Lesi somisi sisebenzisa isifudumezi sikagesi ukushisisa umoya ocindezelwe onwetshiwe, ngaleyo ndlela sinciphise ukusetshenziswa komoya odingekayo ku-8%.Lesi somisi sisebenzisa amandla angaphansi kwama-25% kunesomisi sokuvuselela kabusha esingashisi.
3. Umoya ozungeze isomisi esivuthela kabusha uphephezela ku-heater kagesi bese uthinta i-adsorbent emanzi ukuze ukhiqize kabusha i-adsorbent.Lolu hlobo lwesomisi alusebenzisi umoya ocindezelwe ukuze luvuselele i-adsorbent, ngakho-ke lusebenzisa amandla angaphezu kuka-40% ngaphezu kwesomisi sokuvuselela kabusha esingashisi.
4. Isomisi sokuvuselela ukushisa kokucindezelwa I-adsorbent ekomisweni kokuvuselela ukushisa kokucindezela ivuselelwa ngokusebenzisa ukushisa kokucindezela.Ukushisa kokuvuselela akususiwe ku-aftercooler kodwa kusetshenziselwa ukukhiqiza kabusha i-adsorbent.Lolu hlobo lwesomiso lunganikeza iphuzu lamazolo elicindezela -20°C ngaphandle kokutshalwa kwezimali kwamandla.Amaphuzu amazolo anomfutho ophansi nawo angatholakala ngokungeza izifudumezi ezengeziwe.
Isomisi sokuvuselela ukuqhuma komoya.Ngenkathi umbhoshongo wesokunxele womisa umoya ocindezelwe, umbhoshongo ongakwesokudla uvuselela.Ngemuva kokupholisa nokulinganisa ingcindezi, le mibhoshongo emibili izoshintsha ngokuzenzakalelayo.
Ngaphambi kokumiswa kwe-adsorption, i-condensate kufanele ihlukaniswe futhi ikhishwe.Uma umoya ocindezelwe ukhiqizwa i-compressor ejovwe ngamafutha, isihlungi esikhipha uwoyela kufanele futhi sifakwe phezulu komshini wokomisa.Ezimweni eziningi, isihlungi sothuli siyadingeka ngemva kwesomisi se-adsorption.
Imishini yokomisa yokuvuselela ukushisa yokucindezela ingasetshenziswa kuphela ngama-compressor angenawo uwoyela ngoba ukuvuselelwa kwawo kudinga umoya ophakeme kakhulu wokuvuselela izinga lokushisa.
Uhlobo olukhethekile lokomisa ukushisa okucindezelwayo kokuvuselela umshini wokomisa izigubhu.Lolu hlobo lwesomisi lunesigubhu esijikelezayo ne-adsorbent enamathele kuso, futhi ingxenye yesine yesigubhu ivuselelwa futhi yomiswe umoya oshisayo ocindezelwe ku-130-200 ° C kusuka ku-compressor.Umoya ovuselelwe ube usupholiswa, amanzi okujiya ayakhishwa, bese umoya ubuyiselwa emgudwini oyinhloko womoya ocindezelwe nge-ejector.Enye ingxenye yendawo yesigubhu (3/4) isetshenziselwa ukomisa umoya ocindezelwe ku-compressor aftercooler.
Akukho ukulahlekelwa komoya ocindezelwe endaweni yokomisa ukushisa kabusha kokucindezelwa, futhi imfuneko yamandla ukushayela isigubhu kuphela.Isibonelo, umshini wokomisa onesilinganiso sokugeleza kokusebenza okungu-1000l/s sisebenzisa ugesi ongu-120W kuphela.Ukwengeza, akukho ukulahlekelwa komoya ocindezelwe, asikho isihlungi sikawoyela, futhi asikho isihlungi sothuli esidingekayo.
Isitatimende: Lesi sihloko senziwa kabusha kusukela ku-inthanethi.Okuqukethwe yi-athikili okwezinjongo zokufunda nokuxhumana kuphela.I-Air Compressor Network ihlala ingathathi hlangothi mayelana nemibono ekusihloko.I-copyright ye-athikili ingeyombhali wokuqala kanye nenkundla.Uma kukhona ukwephulwa komthetho, sicela usithinte ukuze ukususe.
