I-ultrasonic cavitation effect ibhekisela kwi-compression alternating kunye nokwandiswa kwama-molecule e-liquid njengoko i-ultrasound isasaza kumanzi. Xa uxinzelelo lwesandi lufikelela kwixabiso elibalulekileyo, amaqamza amancinci amancinci amaninzi enza i-diesel fuel. La maqamza e-cavitation akhula ngokukhawuleza kwaye adilike ngokukhawuleza ngexesha elifutshane kakhulu (i-nanoseconds), ngokukhawuleza akhulule amaqondo okushisa aphezulu kakhulu asekuhlaleni (ngaphezu kwe-5000K) kunye noxinzelelo (amakhulu e-MPa), ngelixa kwangaxeshanye evelisa amaza othusayo anamandla, ii-microjets, kunye nemikhosi yokucheba. Lo mmandla wendalo ogqithiseleyo uphazamisa ukulingana kwesakhiwo se-molecular yasekuqaleni kwi-diesel fuel, ukufezekisa iziphumo ezininzi zonyango: kwelinye icala, i-shear force force force iphula amaqela amakhulu eemolekyuli, amasuntswana angcolileyo, kunye namanzi kwi-fuel ye-diesel kwi-micron okanye i-nanometer - amasuntswana obungakanani, ukuwasasaza ngokufanayo kwi-diesel; ngakolunye uhlangothi, ukushisa okuphezulu kunye noxinzelelo oluveliswa yimpembelelo ye-cavitation ikhawuleza ukuguqulwa kunye nokuhlukana kwamacandelo ayingozi kwi-diesel fuel, ukudala iimeko ezifanelekileyo zokucoca unyango olulandelayo. Ukongeza kwimpembelelo ye-cavitation, i-mechanical effect ye-ultrasound inokuvelisa ngokuqhubekayo okuphezulu - ukunyakaza kwee-frequency kwi-diesel fuel, ukuphucula i-media mixing kunye nokuphucula ukufana kokucubungula. Impembelelo ye-thermal, ngokuguqulwa kwenxalenye yamandla e-ultrasonic, iphakamisa kancane ukushisa kwe-diesel fuel, inceda ukunyusa ukusebenza kakuhle ngaphandle kokulimaza iipropati ezibonakalayo kunye neekhemikhali ze-diesel fuel, ngaloo ndlela igcina iimpawu zayo ze-fuel kuyo yonke inkqubo.
I-ultrasonic diesel emulsification: Ukuphucula ukusebenza kakuhle kokutsha kunye nokunciphisa ukukhutshwa kokungcola.
I-Ultrasonic emulsification yenye yezicelo eziphambili ze-ultrasonic unyango lwe-diesel fuel. Umgaqo wayo oyintloko kukwenza amanzi alinganayo kunye azinzileyo - i-diesel emulsion (WIDE) phantsi kwesenzo se-ultrasonic cavitation, kunye nomxholo wamanzi ngokuqhelekileyo ukusuka kwi-5% ukuya kwi-25%. Ekubeni amanzi kunye ne-diesel fuel i-immiscible, i-cavitation shear force ye-ultrasound inokuphula amaconsi amanzi kwi-nanoscale particles, ihlakaze ngokufanayo ngaphakathi kwe-diesel fuel ukuze yenze inkqubo ye-emulsion ezinzileyo. Oku kuphelisa imfuno yomthamo omkhulu we-emulsifiers yeekhemikhali, okanye kufuna kuphela isixa esincinci ukuphucula uzinzo.
Le mafutha e-diesel emulsified inika iingenelo ezibalulekileyo ngexesha lokutsha: xa ingena kwigumbi lokutsha, amaconsi amanzi aphuphuma ngokukhawuleza kwaye ayanda kumaqondo okushisa aphezulu, aphule ukunyanzeliswa komphezulu we-droplets ye-diesel kunye nokufezekisa i-atomization yesibini. Oku kwandisa kakhulu indawo yoqhagamshelwano phakathi kwamafutha edizili kunye nomoya, okukhokelela ekutshisweni ngokupheleleyo kunye nokunciphisa ngokufanelekileyo ukusetyenziswa kwamafutha malunga ne-5%. Kwezinye iimeko, ukusebenza kakuhle kwamafutha kungaphuculwa nge-15% - 20%. Kwangaxeshanye, inkqubo yokwenziwa komphunga yamathontsi amanzi ifunxa ubushushu obukhulu, inciphisa iqondo lobushushu le-adiabatic lendawo kwigumbi lokutsha, ngaloo ndlela inciphisa ukukhutshwa kwenitrogen oxide (NOx) ukuya kuthi ga kwi-40% kunye nokukhutshwa kwe-particulate matter (PM) ngaphezulu kwe-30%, kwaye kwanokuphelisa ngokupheleleyo, ukuphelisa umsi omdaka owenziwe ngumsi omdaka oveliswa kakhulu. Ngaphaya koko, idizili e-emulsified inokunciphisa idiphozithi yekhabhoni ngaphakathi kweenjini, inciphise ukunxiba kwezixhobo, kwaye yandise ubomi be-injini, iyenze ilungele iimeko zokusetyenziswa kwedizili ezinje ngeenqwelo zokuhamba, iinjini zeenqanawa, kunye neeseti zejenereyitha.
Okwangoku, iinkampani zasekhaya zifezekisele enkulu-imveliso enkulu ye-ultrasonic emulsified diesel izixhobo, kunye neyunithi yokucubungula enye ukuya kwiitoni ezingama-20 ngosuku kunye nokuzinza kwe-emulsification (akukho stratification emva kweeyure ezingama-48) ukufikelela kwi-99%. Esi sixhobo sisetyenziswe kwiiprojekthi zokuphucula amafutha kwiinkampani ezifana neSinopec kunye nePetroChina, inceda iinkampani ezinkulu ze-logistics ukunciphisa kakhulu iindleko zepetroli.
