Inqubo yokomisa isomisi esibandayo kanye ne-aftercooler emoyeni ocindezelwe
Wonke umoya osemkhathini uqukethe umhwamuko wamanzi: ungaphezulu emazingeni okushisa aphezulu futhi ube mncane emazingeni okushisa aphansi.Lapho umoya ucindezelwa, ukuminyana kwamanzi kuyanda.Isibonelo, i-compressor enengcindezi yokusebenza ye-7 bar kanye nezinga lokugeleza elingu-200 l/s lingakhulula u-10 l/h wamanzi epayipini lomoya elicindezelwe ukusuka ku-20 ° C emoyeni onomswakama ohlobene no-80%.Ukuze ugweme ukuphazanyiswa ukufiphala kwamapayipi kanye nemishini yokuxhuma, umoya ocindezelweyo kufanele wome.Inqubo yokomisa isetshenziswa ku-aftercooler kanye nemishini yokomisa.Igama elithi “pressure dew point” (PDP) lisetshenziselwa ukuchaza okuqukethwe kwamanzi emoyeni ocindezelwe.Kubhekiselwa ezingeni lokushisa lapho umhwamuko wamanzi uqala ukuminyana ube amanzi ngomfutho osebenzayo wamanje.Inani eliphansi le-PDP lisho ukuthi kunomusi omncane wamanzi emoyeni ocindezelweyo.
Icompressor enamandla omoya angu-200 amalitha ngesekhondi izokhiqiza cishe amalitha ayi-10 ngehora amanzi ajiyile.Ngalesi sikhathi, umoya ocindezelwe ungu-20°C.Ngenxa yokusetshenziswa kwama-aftercoolers kanye nemishini yokomisa, izinkinga ezibangelwa ukufiphala kwamapayipi nemishini ziyagwenywa.
Ubudlelwano phakathi kwendawo yamazolo kanye nendawo yokucindezela
Into okufanele uyikhumbule lapho uqhathanisa okokomisa okuhlukile akukhona ukudida indawo yamazolo esemkhathini nendawo yokucindezela yamazolo.Isibonelo, iphuzu lamazolo okucindezela ku-7 bar kanye no-+2 ° C lilingana nendawo evamile yokucindezela kwamazolo ku -23 ° C.Ukusebenzisa isihlungi ukususa umswakama (ukwehlisa indawo yamazolo) akusebenzi.Lokhu kungenxa yokuthi ukupholisa okwengeziwe kubangela ukuqhubeka kokucinana komhwamuko wamanzi.Ungakhetha uhlobo lwemishini yokomisa ngokusekelwe endaweni yokucindezela amazolo.Uma kucatshangelwa izindleko, lapho imfuneko yezinga lamazolo iphansi, iba nkulu imali etshaliwe kanye nezindleko zokusebenza zokomisa umoya.Kunobuchwepheshe obuhlanu bokukhipha umswakama emoyeni ocindezelwe: ukupholisa kanye nokuhlukanisa, ukucindezela ngokweqile, ulwelwesi, ukumuncwa kanye nokomisa kwe-adsorption.
i-aftercooler
I-aftercooler isishintshi sokushisa esipholisa igesi ecindezelwe eshisayo, evumela umhwamuko wamanzi kugesi ocindezelwe oshisayo ukuthi uminyene ube emanzini abengacinana ohlelweni lwamapayipi.I-aftercooler ipholile ngamanzi noma ipholile emoyeni, ngokuvamile inesehlukanisi samanzi, esikhipha amanzi ngokuzenzakalelayo futhi siseduze ne-compressor.
Cishe u-80-90% wamanzi ahlanganisiwe aqoqwa kusihlukanisi samanzi se-aftercooler.Izinga lokushisa lomoya ocindezelwe odlula ku-aftercooler ngokuvamile lizoba ngu-10°C ngaphezu kwezinga lokushisa lendawo yokupholisa, kodwa lingase lihluke kuye ngohlobo lokupholisa.Cishe wonke ama-compressor amile ane-aftercooler.Ezimweni eziningi, i-aftercooler yakhelwe ku-compressor.
Ama-aftercoolers ahlukene kanye nezihlukanisi zamanzi.Isihlukanisi samanzi singahlukanisa amanzi ajiyile emoyeni ocindezelwe ngokushintsha isiqondiso nesivinini sokugeleza komoya.
Isomisi esibandayo
Ukumisa iqhwa kusho ukuthi umoya ocindezelweyo uyapholiswa, ufihlwe futhi uhlukaniselwe amanzi amaningi ajiyile.Ngemva kokuba umoya ocindezelwe usupholile futhi ujiyile, ushiselwa ekamelweni lokushisa futhi ukuze ukufingqa kungenzeki futhi ngaphandle komgudu.Ukushintshaniswa kokushisa phakathi kokungena komoya ocindezelwe kanye nokukhishwa akukwazi nje ukunciphisa izinga lokushisa lokungenisa umoya ocindezelweyo, kodwa futhi kunciphise umthwalo wokupholisa wesekethe yesiqandisi.
Ukupholisa umoya ocindezelwe kudinga isistimu yesiqandisi evaliwe.I-compressor yesiqandisi enokulawula ukubala okuhlakaniphile inganciphisa kakhulu ukusetshenziswa kwamandla kwesomisi esiqandisi.Imishini yokomisa esiqandisini isetshenziselwa igesi ecindezelwe enephuzu lamazolo phakathi kuka +2°C no +10°C kanye nomkhawulo ophansi.Lo mkhawulo ophansi uyindawo yokubanda kwamanzi ajiyile.Zingaba idivayisi ehlukile noma eyakhelwe ku-compressor.Inzuzo yalokhu yokugcina ukuthi ithatha indawo encane futhi ingaqinisekisa ukusebenza kwe-compressor yomoya efakwe ngayo.
Izinguquko zepharamitha ezijwayelekile zokuminyanisa, ukupholisa ngemva kokupholisa kanye nokomisa iqhwa
Igesi eyisiqandisi esetshenziswa kumshini wokomisa isiqandisi inamandla aphansi okufudumala kwembulunga yonke (GWP), okusho ukuthi lapho i-desiccant ikhishwa ngephutha emkhathini, akunakwenzeka ukuthi ibangele ukufudumala kwembulunga yonke.Njengoba kushiwo emthethweni wezemvelo, iziqandisi zesikhathi esizayo zizoba namanani aphansi e-GWP.
Okuqukethwe kuvela ku-inthanethi.Uma kukhona ukwephulwa komthetho, sicela usithinte
