Qhov zoo ntawm Ultrasonic Emulsification Technology hauv Kev Tsim Cov Roj emulsified

Emulsion roj yog ib qho emulsion uas muaj cov dej thiab cov nplaim taws (roj los yog roj). Feem ntau siv emulsion roj hauv kev tsim khoom yog dej emulsion ua los ntawm emulsification ntawm diesel thiab dej. Diesel thiab dej emulsion fuels muab ntau dua combustion thiab kev siv roj ntau dua, thaum tsim cov khib nyiab tsawg los ntawm kev hlawv roj.

Cov khoom siv emulsification

Txij li thaum siv cov roj emulsified tuaj yeem txo cov roj siv, nws kuj ncaj qha txo cov nqi tsim khoom. Nws kuj tseem txo cov roj tsev cog khoom xws li carbon dioxide (CO2), nitrogen oxides (NOx), thiab sulfur oxides (SOx), yog li nyiam cov roj tshiab uas zoo ib puag ncig zoo.

Kev sib piv ntawm diesel thiab emulsion roj combustion

kev cuam tshuam ib puag ncig

Kev sib xyaw ntawm cov roj ib txwm muaj (diesel, roj av, thiab lwm yam) tso tawm ntau cov pa phem xws li nitrous oxide (NOx), hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO2), thiab cov khoom me me (PM. ) thiab cov pa luam yeeb dub. Vim yog kev siv cov cuab yeej siv no, qhov cuam tshuam rau ib puag ncig yog loj heev.

Tib neeg kev noj qab haus huv cuam tshuam

Kev sib xyaw ntawm cov roj ib txwm tso tawm cov tshuaj lom thiab tsis zoo, xws li sulfur dioxide, ozone, sulfate, thiab cov tshuaj lom xws li formaldehyde thiab benzene. Cov kab uas hla ntawm cov tshuaj no yog me me, uas yog ib qho yooj yim rau nqus tau los ntawm tib neeg lub cev thiab muaj feem xyuam rau tib neeg noj qab haus huv.

Qhov zoo ntawm cov khoom siv ultrasonic emulsification

Ultrasonic emulsification yog cov txheej txheem yooj yim thiab siv tau los tsim cov roj emulsions ruaj khov nrog nanoscale droplets (nanoemulsions). Lub zog tsav ntawm phacoemulsification yog acoustic cavitation, uas ua rau muaj kev kub ntxhov thiab asymmetric bursting lub tshuab nqus tsev npuas thaum lub sijhawm ua haujlwm, ua rau microjets thiab muaj zog shear rog uas tawg cov tee rau hauv nanometer qhov ntau thiab tsawg. Ultrasonic emulsification khoom tuaj yeem tau txais ib qho emulsion ntawm cov roj hauv paus (xws li diesel lossis kerosene) thiab dej. Cov emulsions no tuaj yeem txo qis cov pa phem no thaum siv.

Cov txiaj ntsig ib puag ncig

Hais txog cov txiaj ntsig ntawm ib puag ncig, roj emulsions yog ib qho ntawm lwm txoj hauv kev rau cov roj hluav taws xob xws li roj av. Nws tuaj yeem siv rau hauv cov tshuab tsis hloov kho diesel thiab tuaj yeem txo cov pa roj nitrous oxide emissions los ntawm kwv yees li 35 % vim tias cov dej hauv cov roj emulsion txo qhov kub ntawm cov nplaim taws hauv zos. Tsis tas li ntawd, txij li cov roj sonicated kub hnyiab ntau dua, cov khoom me me uas tsim los ntawm cov txheej txheem combustion tuaj yeem txo los ntawm kwv yees li 60 %. Kev siv cov roj emulsified kuj txo qhov ua rau muaj kuab paug ib puag ncig.

Cov txiaj ntsig nyiaj txiag

Tseem muaj cov txiaj ntsig kev lag luam tam sim rau kev siv sonication fuels. Dej hauv emulsified roj txhim kho roj atomization thiab combustion efficiency, yog li txo cov roj noj. Txij li thaum dej boils ntawm qhov kub qis dua li roj, nws evaporates yooj yim thaum rhuab. Ntawm" superheat txwv kub" ntawm txog 270 degree, micro - tawg ntawm cov dej zoo tshwm sim thoob plaws hauv cov roj emulsified. Qhov no tseem tso cai rau kev sib xyaw kom zoo ntawm cov roj thiab cua hauv lub cav. Tsis tas li ntawd, dej kuj tuaj yeem hloov tau ib feem ntawm cov roj, thiab qhov poob ntawm lub zog feem ntau yog them los ntawm kev nce hauv kev sib xyaw ua haujlwm ntawm cov roj seem.

Ua kom muaj kev ruaj ntseg

Lub stability ntawm cov roj emulsified npaj los ntawm ultrasonic emulsification yog siab, yog li tsis muaj surfactant ntxiv yuav tsum tau stabilize lub emulsion. Lub zog shear quab yuam ntawm cov cuab yeej ultrasonic zoo rau kev tsim cov nanoemulsions ruaj khov. Txawm hais tias kev yuav khoom ntawm cov khoom siv ultrasonic ua rau cov nqi tsim khoom ntxiv, cov nqi no feem ntau cuam tshuam los ntawm cov txiaj ntsig ntawm kev txo cov nyiaj surfactant xav tau hauv cov txheej txheem emulsification.
