Imitha yokuHamba koMbane weCO2
Ukulinganisa ngokuchanekileyo kusisiseko sokusebenza kakuhle, ukuchaneka kunye nokuzinza kwiindawo ezininzi zoshishino, amacandelo okusingqongileyo kunye neenkqubo zesayensi. Ukulinganisa ukuhamba kwe-CO₂ yeyona nto iphambili kwiinkqubo ezichaphazela ubomi bethu bemihla ngemihla kunye neplanethi yethu, nto leyo ebonisa umahluko omkhulu phakathi kokungasebenzi kakuhle okuphumelelayo nokubiza kakhulu.
Amazwe Jikelele eCarbon Dioxide
I-carbon dioxide ikhona kwiimeko ezine -- igesi, ulwelo, i-supercritical kunye ne-solid iyonke kwiimeko ezahlukeneyo zobushushu kunye noxinzelelo. Nangona kunjalo, ezo meko zine zinemingeni eyahlukeneyo yokucubungula ukufikelela kwimingeni ethile yokuphatha kunye nokulinganisa.
I-carbon dioxide enegesiIsetyenziswa kakhulu ekukhuliseni izityalo eziluhlaza, kwiinkqubo zokucima umlilo kwanakwiipakethe zokutya ukuze zigcinwe ixesha elide.Ikhabhoni dayokhsayidi engamanziIfezekiswa ngokuxhomekeke kuxinzelelo oluphezulu kunye namaqondo obushushu aphantsi, kuba yinto ebaluleke kakhulu kwizicelo ezifana nokufakwa kwekhabhoni kwiziselo, ukubanda kunye nokuthuthwa koxinzelelo oluphezulu.
I-supercritical co2ifunyanwa isetyenziswa ekubuyiseleni ioyile ngcono, ekuthuthweni kwekhabhoni nanjengesinyibilikisi kwiinkqubo zokukhupha;2, eyaziwa ngokuba ngumkhenkce owomileyo, isetyenziswa kakhulu ekupholiseni, ekulondolozeni, kwiziphumo ezikhethekileyo nasekucoceni kwimizi-mveliso.
Imingeni ekulinganiseni i-co2
Ngenxa yokwahluka kwayo okungaqhelekanga kwiimeko ezahlukeneyo, kukho imingeni emininzi yobuchwephesha ekulinganisweni kokuhamba kwamanzi, ingakumbi ukulinganisa ngokuchanekileyo kwegesi.2Ifuna uhlengahlengiso oluqhubekayo ukuze ifikelele kwimigangatho yokucubungula ukucinezeleka kwayo kunye nobuthathaka kubushushu. Neempazamo ezincinci ekulinganisweni zinokubangela umahluko omkhulu.
Iindawo ezinoxinzelelo oluphezulu kunye nomngcipheko wokuqhekeka kwe-cavitation zinokuphazamisa ukusebenza kweemitha zokuhamba zemveli. Ngaphandle koko, ukungcola kunye notshintsho lwesigaba ekuthuthweni zizizathu zeempazamo xa kufakelwa imitha yokuhamba engalunganga ekulinganisweni kwemizi-mveliso.
Ubuninzi kunye nokuguquguquka kwe-viscosity kushiya umlinganiselo ochanekileyo unzima ngakumbi kwiinkqubo ezibaluleke kakhulu, apho izixhobo kufuneka zilungelelaniswe kwiimpawu eziguqukayo kwaye zigcinwe ngokuchanekileyo okufunekayo.
Imisebenzi yeeMeter zeCO₂ Mass Flow
Iimitha yokuhamba kwegesi yekhabhoni dayokhsayidisisixhobo esizinikeleyo esenzelwe ukujonga ukuhamba kobuninzi be-co2ngokusebenzisa inkqubo. Injongo yale mitha ikukugcina ukuchaneka kokulinganiswa kokuhamba kwamanzi kumaqondo obushushu ahlukeneyo kunye noxinzelelo. Zisetyenziswa kumashishini amaninzi, ukusuka ekutyeni naseziselo ukuya kwioyile negesi. Ke ngoko, abaqhubi bayakwazi ukujonga nokulawula i-CO22ukusetyenziswa, ukunciphisa inkunkuma kunye nokuhlangabezana nemigangatho engqongqo yokusingqongileyo kunye nokucubungula.
Imigaqo yokusebenza ye-CO₂ Mass Flow Meter
Aimitha yokuhamba kwekhabhoni dayokhsayidiulinganisa ukuhamba komoya odlula kwinkqubo ngokuthe ngqo okanye ngokungathanga ngqo, oko kukuthi umlinganiselo wokuhamba kobunzima ngokuthe ngqo okanye ngokungathanga ngqo. Kanye njengoko igama layo lisitsho, umlinganiselo wokuhamba kobunzima ngokuthe ngqo ujonga izinga lokuhamba ngokweempawu zomzimba ze-CO2; umlinganiselo wokuhamba ngokungathanga ngqo ubale ukuhamba kobunzima ngeparameters ezingathanga ngqo ezifana noxinano lolwelo kunye neemeko zokuhamba.
Umzekelo, imitha yokuhamba kobunzima beCoriolis kunye nemitha yokuhamba kobunzima bobushushu zonke zizixhobo zokulinganisa ukuhamba kobunzima ngokuthe ngqo, ukulinganisa i-inertia kunye nokusasazwa kobushushu bokuhamba kokuhamba. Imitha yokuhamba koxinzelelo oluhlukileyo (DP) ngumzekelo wokulinganisa ngokungathanga ngqo, okuqinisekisa ukuhamba kobunzima ngokuhla koxinzelelo. Ngokubanzi, ukulinganisa ngokungathanga ngqo okusetyenziswayo ekucutshungulweni kwemizi-mveliso kufuna imbuyekezo yobushushu kunye noxinzelelo ukuze kufumaneke ukuchaneka okuphezulu.
Ngamafutshane, iimitha zokuhamba kobunzima obungathanga ngqo ziqikelela amazinga okuhamba ngemilinganiselo yesibini efana noxinzelelo, ubushushu kunye nomthamo. Nangona zisebenza ngeendlela ezahlukeneyo kwaye zisebenza kakuhle, zincinci ekulawuleni iimitha zokuhamba kobunzima ngokuchanekileyo. Ngokwahlukileyo koko, iimitha zokuhamba kobunzima ezithe ngqo zilinganisa amazinga okuhamba ngokuthe ngqo, akukho mfuneko yokuhlawula naluphi na ubushushu. Ngoko ke iimitha zobushushu okanye zeCoriolis zifanelekile kwizicelo ezitshintshayo okanye ezichanekileyo.
Iimveliso ezicetyiswayo zokulinganisa i-CO2
Imitha Yokuhamba KweCoriolis yokulinganisa Ukuhamba Kobunzima beCO2
Imitha yokuhamba kobunzima beCoriolis isebenza ngokomgaqo we-inertia, oveliswa yi-mass ehambayo edlula kwiityhubhu ezingcangcazelayo. Utshintsho lwesigaba ngumsebenzi wesantya sokuhamba kobunzima, ofikelela kwiinjongo zokulinganisa ngobuchule nangokuchanekileyo.
Iimpawu zeMveliso:
✤Ukuchaneka okugqwesileyo ngaphakathi kwe-0.1%
✤Iyasebenziseka xa kulinganiswa i-CO2 elulwelo kunye negesi
✤ Akuxhomekekanga kubushushu kunye nokuguquguquka koxinzelelo
✤ Ukubeka esweni uxinano oluthembekileyo ngexesha langempela
Ukongeza kwezi mpawu zingasentla, isasebenza ekulinganiseni ukuhamba kwe-CO2 okubangelwa yimeko yayo yolwelo kumaqondo obushushu aphantsi, ingakumbi ekumelaneni neemeko ezinzima kakhulu. Ingalinganiswa ukuze ifikelele ekuchanekeni okuthile nangona kukho utshintsho olukhawulezileyo kumaqondo obushushu.
Iimitha zokuhamba kobushushu zisebenza ngokungenisa ubushushu kwigesi kwaye zilinganise umahluko wobushushu phakathi kweesensa ezimbini. Oku kwehla kobushushu kubangelwa yimpendulo ye-endothermic njengoko i-CO2 idlula ukusuka kwesinye isensa ukuya kwesinye. Isantya sokuhamba kwegesi sinokubalwa ngeso sokulahleka kobushushu, esihambelana ngokuthe ngqo nesantya sokuhamba kwegesi.
Iimpawu zeMveliso:
✤Iyasebenza kwiindlela zokulinganisa ukuhamba kwamanzi eziphantsi njengezilingo zelebhu
✤Ukubonelela ngokufundwa okuchanekileyo kwe-CO2 enegesi
✤Ulondolozo oluncinci kwisakhiwo sayo esilula -- akukho zinto zishukumayo
✤Uyilo oluncinci kunye nokusebenza kakuhle okuphezulu
Ngokuqonda imingeni yokulinganisa i-CO₂, ukukhetha imitha yokuhamba kobunzima efanelekileyo, kunye nokusebenzisa iingenelo ezikhethekileyo zobuchwepheshe ezifana neCoriolis kunye neemitha zokuhamba kobushushu, amashishini angenza ngcono iinkqubo zawo, anciphise iindleko, kwaye aqinisekise ukuthotyelwa kwemigangatho yokusingqongileyo. Nokuba ujongene ne-CO₂ yegesi ekujongeni ukukhutshwa komoya okanye i-CO₂ engamanzi ekupholiseni kwemizi-mveliso, imitha yokuhamba kobunzima efanelekileyo sisixhobo esibalulekileyo sempumelelo.
