Vim li cas Ib qho Ultrasonic Atomizing Nozzle Muaj Lub Cua Ncauj?

Cov cua nkag (tseem hu ua "ejector gas / auxiliary gas inlet") ntawm ib qho ultrasonic atomizing nozzle yog ib qho ntawm nws cov qauv tsim. Nws txoj haujlwm ncaj qha ua haujlwm los txhim kho cov teebmeem atomization, tswj cov qauv tshuaj tsuag, thiab hloov mus rau daim ntawv thov scenarios. Qhov tseem ceeb, nws hais txog cov kev txwv ntawm cov ntshiab ultrasonic atomization los ntawm cov ntsiab lus roj dynamics. Cov hauv qab no yog cov ncauj lus kom ntxaws los ntawm peb qhov loj me: cov qauv kev ua haujlwm, cov haujlwm tseem ceeb, thiab cov ntawv thov scenarios.

Peb Lub Luag Haujlwm Tseem Ceeb ntawm Kev Qhia Gas Inlet (nrog Cov Ntsiab Cai)

1. Secondary Atomization: Droplet Refinement + Tiv thaiv kev sib tsoo

♦ Txoj Cai:Tom qab nkag mus rau hauv lub inlet, cov roj qhia tau ejected ntawm kev kub ceev (ntev npaum li cas mus txog 20-50 m / s) raws cov huab cua sab hauv ntawm lub nozzle, tsim ib tug "shearing nyhuv" nrog cov thawj tee generated los ntawm lub ultrasonic transducer- lub high-ceev airflow ua zoo li txiab, ntxiv rhais li agglomerated poob. Nyob rau tib lub sijhawm, cov roj molecules sib tsoo nrog cov tee dej, rhuav tshem nws cov adhesion.

♦ Cov nyhuv:Droplet loj yog ntxiv refined los ntawm 5-10 μm nyob rau hauv cov ntshiab ultrasound mus rau 1-5 μm (los yog txawm nanometer scale, nyob ntawm seb cov roj siab), thiab cov tee dej yog uniformly dispersed tsis muaj loj droplet nyob.

♦ Qhov tseem ceeb Parameter:Gas siab feem ntau hloov mus rau 0.1-0.5 MPa. Kev kub siab ua rau muaj zog dua theem nrab atomization (tab sis yuav tsum tau muab sib xyaw nrog cov kua dej ntws kom tsis txhob muaj dej ntau dhau).

2. Kev Taw Qhia Kev Txhaum Cai + Nthuav Ntxov Ntau

♦ Txoj Cai:Cov cua guiding muab "thrust," propelling lub atomized droplets tawm nyob rau hauv ib tug predetermined kev taw qhia (xws li, axial los yog radial). Nyob rau tib lub sijhawm, cov cua ntws tawm mus, ua rau cov tee dej los npog thaj tsam loj dua.

♦ Cov teebmeem:Cov tshuaj tsuag ntau ntxiv los ntawm<30cm for pure ultrasonic spraying to 1-5m (adjustable via the nozzle structure), enabling directional spraying (e.g., precise spraying onto the workpiece surface) and fan-shaped spraying (coverage width can reach 0.5-2m).

♦ Daim Ntawv Thov Scenario:Industrial humidification, pre-kev kho mob rau txheej txheej, flue gas desulfurization thiab denitrification (yuav tsum muaj kev sib cuag txaus ntawm cov tee dej thiab cov roj flue), kev tiv thaiv cog qoob loo (ntev- tshuaj tua kab deb), thiab lwm yam.

3. Anti-clogging + Txias Transducer, Txhim kho cov cuab yeej ruaj khov

♦ Txoj Cai:Thaum lub siab -ceev airflow hla saum npoo ntawm ultrasonic transducer, nws nqa tawm cov kua seem thiab cov khoom me me, tiv thaiv clogging ntawm transducer lub orifice. Nyob rau tib lub sijhawm, cov cua ntws muaj qhov ua kom txias, txo cov cua sov uas tsim los ntawm cov khoom siv hluav taws xob vim yog lub sijhawm ntev heev - zaus vibration.

♦ Cov txiaj ntsig:Haum rau siab -cov kua viscosity (xws li cov tshuaj ncua kev kawm uas muaj 10-20% cov khoom, thiab cov roj uas muaj viscosity <50 mPa·s); Transducer kev khiav hauj lwm kub yog tswj hauv qab 60 degree, ncua kev pab cuam lub neej (ntshiab ultrasonic transducers yog nquag rau lub hwj chim attenuation vim overheating).

4. Assisted Droplet Evaporation (rau cov xwm txheej tshwj xeeb)

♦ Txoj Cai:Siv cov roj rhuab (xws li, 60-120 degree) rau kev qhia huab cua tuaj yeem ua kom cov dej ntws tawm sai, tsim nyog rau cov xwm txheej uas yuav tsum tau ziab sai sai (xws li, kho sai ntawm cov txheej nyias nyias, cov khoom siv hluav taws xob humidified).

♦ Daim ntawv thov txuas ntxiv:Ultrasonic atomization humidification ua ke nrog cov cua kub taw qhia tuaj yeem ua tiav "isothermal humidification," tsis txhob poob qis hauv qhov kub thiab txias (piv txwv li, hauv cov khoom siv hluav taws xob hauv kev cob qhia thiab cov chaw soj nstuam).
