co2 Imitha yokuHamba kweMisa
Umlinganiselo ochanekileyo uquka umqolo wempumelelo, ukuchaneka kunye nokuzinza kwiinkalo ezininzi zoshishino, amacandelo okusingqongileyo kunye neenkqubo zesayensi. Umlinganiselo wokuhamba kwe-CO₂ ngundoqo weenkqubo ezichaphazela ubomi bethu bemihla ngemihla kunye neplanethi, ukupela umahluko omkhulu phakathi kokungasebenzi kakuhle kunye neendleko.
Jikelele States of Carbon Dioxide
Ikharbhon dayoksayidi ikhona kumazwe amane--igesi, ulwelo, i-supercritical kwaye iqinile iyonke kubushushu obahlukeneyo kunye neemeko zoxinzelelo. Nangona kunjalo, la mazwe mane anika imiceli mngeni eyahlukeneyo yokusetyenzwa ukufikelela kwimingeni ethile yokuphatha kunye nokulinganisa.
I-carbon dioxide enegesiisetyenziswa ngokubanzi kwi-greenhouse enrichment, iinkqubo zokucima umlilo kunye nakwipakethe yokutya ukwenzela ukulondolozwa kwexesha elide.Ulwelo carbon dioxideiphunyezwa ngokuphantsi koxinzelelo oluphezulu kunye namaqondo obushushu aphantsi, ayimfuneko kwizicelo ezifana nekhabhoni yesiselo, ifriji kunye nokuthuthwa koxinzelelo oluphezulu.
I-supercritical co2ifunyenwe isetyenziswe ekuphuculweni kwe-oyile ephuculweyo, ukuhluthwa kwekhabhoni kunye nanjenge-solvent kwiinkqubo zokukhutshwa; eqinile co2, eyaziwa ngokuba yiqhwa elomileyo, ngokuqhelekileyo lisetyenziselwa ukupholisa, ukugcinwa, iziphumo ezikhethekileyo kunye nokucoca kwamashishini.
Imingeni kwi-Measuring co2
Ngenxa yokwahluka kwayo okukhethekileyo kwiimeko ezahlukeneyo, kukho imiceli mngeni emininzi yobugcisa kumlinganiselo wokuqukuqela, ngakumbi umlinganiselo ochanekileyo wegesi yegesi.2. Ifuna ukulungiswa rhoqo ukufikelela kwimigangatho yokucubungula ukunyanzeliswa kwayo kunye nobushushu bobushushu. Kwaneempazamo ezincinci kumlinganiselo zinokubangela ukungafani okukhulu.
Iindawo zoxinzelelo oluphezulu kunye nomngcipheko we-cavitation unokunciphisa ukusebenza kweemitha zokuhamba eziqhelekileyo. Ngaphandle koko, ukungcola kunye nokutshintshwa kwesigaba kwizothutho zizizathu zeempazamo kwimeko xa kufakwa imitha yokuhamba engalunganga kumlinganiselo woshishino.
Ukuxinana kunye nokuguquguquka kwe-viscosity kushiya umlinganiselo ochanekileyo onzima kakhulu kwiinkqubo eziphezulu, apho izixhobo kufuneka zilungelelaniswe kwiipropati eziguqukayo kwaye zigcinwe ukuchaneka okufunekayo.
Imisebenzi ye-CO₂ Mass Flow Meters
Iimitha yokuhamba kwegesi yecarbon dioxidesisixhobo esizinikeleyo esilungiselelwe ukujonga ukuhamba kobuninzi be-co2ngenkqubo. Iinjongo zezi mitha zilele ekugcineni ukuchaneka komlinganiselo wokuhamba kumaqondo obushushu ahlukeneyo kunye noxinzelelo. Zisetyenziswa kumashishini amaninzi, ukusuka ekutyeni kunye nesiselo ukuya kwioli kunye negesi. Ngoko ke, abaqhubi bayakwazi ukubeka iliso kunye nokulawula i-CO2ukusetyenziswa, ukunciphisa inkunkuma kunye nokuhlangabezana nemigangatho engqongqo yokusingqongileyo kunye nokulungiswa.
Imigaqo yokusebenza ye-CO₂ Mass Flow Meter
Aimitha yokuhamba kwekharbon dioksideilinganisa ukuhamba okudlulayo kwinkqubo ngokuthe ngqo okanye ngokungathanga ngqo, oko kukuthi, umlinganiselo othe ngqo okanye ongathanga ngqo wobunzima. Kanye njengoko igama layo lisitsho, umlinganiselo othe ngqo wokuqukuqela kobunzima ubeka iliso kwisantya sokuqukuqela ngokweempawu ezibonakalayo zeCO2; umlinganiselo wokuqukuqela ongathanga ngqo ubale ukuhamba kobunzima kusetyenziswa iiparamitha ezingathanga ngqo ezifana noxinaniso lolwelo kunye neemeko zokuqukuqela.
Umzekelo, imitha yokuqukuqela kobunzima beCoriolis kunye nemitha yokuqukuqela kobunzima bobushushu zonke zizixhobo zomlinganiselo othe ngqo wokuqukuqela kobunzima, ukulinganisa inertia kunye nokutshatyalaliswa kobushushu bokudlula okudlulayo. Uxinzelelo oluhlukeneyo (DP) imitha yokuhamba ngumzekelo wokulinganisa okungathanga ngqo, ukunyanzeliswa kokuhamba kobunzima ngokuhla koxinzelelo. Ngokubanzi, umlinganiselo ongathanga ngqo osetyenziswa ekuqhubeni ishishini kufuna imbuyekezo yobushushu kunye noxinzelelo lokuchaneka okuphezulu.
Isishwankathelo, iimitha zokuqukuqela kobunzima obungathanga ngqo zithomalalisa amazinga okuqukuqela ngeeparamitha zesibini ezifana noxinzelelo, ubushushu kunye nomthamo. Ngaphandle kokuguquguquka kwazo kunye nokusebenza kakuhle kweendleko, zincinci ukuba ziqondise iimitha zokuhamba ngobunzima ngokuchanekileyo. Ngokuchasene noko, iimitha zokuhamba ngobunzima obuthe ngqo zilinganisa amanqanaba okuhamba ngokuthe ngqo, akukho mfuneko kuyo nayiphi na imbuyekezo yobushushu. Ke iimitha ze-thermal okanye ze-Coriolis zifanelekile kwizicelo eziguquguqukayo okanye ezichanekileyo.
Iimveliso ezicetyiswayo kuMlinganiselo weCO2
I-Coriolis Flow Meter ye-CO2 Mass Flow Measurement
Imitha ye-Coriolis mass flow meter isebenza kumgaqo we-inertia, oveliswa bubunzima obuhambayo obudlula kwiityhubhu ezingcangcazelayo. Ukutshintshwa kwesigaba ngumsebenzi wesantya sokuhamba kobunzima, ukufikelela kwiinjongo zokulinganisa okuhlakaniphile kunye ngokuchanekileyo.
Iimpawu zeMveliso:
