Cov nyhuv thiab mechanism ntawm ultrasonic demulsification ntawm roj av

1. Cov roj uas muaj dej hauv cov roj ultrasonic demulsification yog ib qho tshwm sim nyob rau hauv kev loj hlob ntawm cov roj thiab roj av, thiab cov dej uas muaj cov roj crude yuav tsum tau dehydrated thiab desalted ua ntej ua. Ultrasonic roj demulsification yog ib txoj kev demulsification tshiab uas tuaj yeem daws cov teeb meem zoo li no.

2, ultrasonic yoj yog ib hom elastic mechanical yoj propagating nyob rau hauv nruab nrab, nrog txhua yam kev co, cavitation thiab thermal ua. Lub suab ntawm ultrasonic crude roj demulsification yuav tsum tau qis dua qhov pib cavitation.

3, yog li ntawd, ultrasonic crude roj demulsification yog tsuas yog siv ultrasonic mechanical vibration thiab thermal ua.

4, ultrasonic yoj yog ib hom elastic mechanical yoj propagating nyob rau hauv nruab nrab, nrog txhua yam kev co, cavitation thiab thermal ua. Theoretical derivation thiab visualization sim ua pov thawj tias lub suab ntawm ultrasonic demulsification yuav tsum tau qis dua qhov pib ntawm cavitation. Yog li ntawd, ultrasonic demulsification ntawm cov roj crude tsuas yog siv ultrasonic mechanical vibration thiab thermal ua.

5, vibration nyhuv los txhawb lub condensation ntawm dej "particles". Thaum lub ultrasonic nthwv dej dhau los ntawm cov roj av nruab nrab nrog cov dej tshem tawm "particles", nws ua rau cov dej tshem tawm "particles" vibrate nrog cov roj crude. Vim tias cov dej "particles" ntawm ntau qhov sib txawv muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, cov dej "cov khoom" yuav sib tsoo nrog ib leeg thiab kev sib raug zoo, ua rau lub ntim thiab qhov loj ntawm cov khoom nce, thiab tom qab ntawd txiav thiab sib cais.

6, cov nyhuv vibration tuaj yeem ua rau paraffin, cov pos hniav, asphalt thiab lwm yam ntuj emulsifiers hauv cov roj crude dispersed tusyees, nce nws cov solubility, txo cov neeg kho tshuab degree ntawm cov roj-dej interface zaj duab xis, yog qhov zoo rau kev sib haum xeeb thiab kev sib cais ntawm cov dej theem. Thermal action txo qhov degree ntawm roj - dej interfacial zaj duab xis thiab roj viscosity.

7. Ntawm ib sab: ciam teb kev sib txhuam ua rau kom qhov kub thiab txias ntawm cov roj-dej ciam teb, uas yog conducive rau tawg ntawm lub interface zaj duab xis.

8, ntawm qhov tod tes: cov roj crude absorbs ib feem ntawm lub zog acoustic rau hauv lub zog hluav taws xob, tuaj yeem txo cov viscosity ntawm cov roj crude, yog qhov zoo rau cov dej "particle" ntawm cov roj thiab dej nqus dej sib cais. Summary: Lub luag hauj lwm ntawm ultrasonic roj demulsification thiab mechanism ntawm me me tsim los qhia qhov no, tom qab nyeem ntawv no koj yuav tsum muaj ib tug yooj yim to taub thiab nkag siab Kuv ntseeg hais tias peb sawv daws to taub nws! Zuag qhia tag nrho, kuv vam tias nws yuav pab tau.
