Title:
METHOD AND APPARATUS FOR PREVENTING SLUDGE SEDIMENTATION IN ELECTRO-DESALTING DRUM BY MEANS OF ULTRASONIC WAVES
Document Type and Number:
WIPO Patent Application WO/2020/238163
Kind Code:
A1
Abstract:
A method and apparatus for preventing sludge sedimentation in an electro-desalting drum by means of ultrasonic waves. Crude oils are mixed and then enter an ultrasonic wave acting apparatus (12). In the ultrasonic wave acting apparatus (12), ultrasonic waves having an acting mode in which parallel through-beam ultrasonic waves (10) and pipe reflective ultrasonic waves (9) are mixed are formed by means of a structure of an ultrasonic acting area. The ultrasonic waves are superimposed to implement a standing wave field effect. Ultrasonic wave reflection produces limitless extension, a combined action of a standing wave field and the thorough-coverage limitless extension performs ultrasonic treatment on the mixed crude oils, and after the treatment is completed, the mixed crude oils enter an electro-desalting drum (15) for electro-desalting. The method and apparatus are used for resolving the production technology problem of sludge sedimentation in an electro-desalting drum, implements continuous production of an electro-desalting drum during a three-year to four-year long-term production process of an oil refinery, avoids the maintenance work of abnormally stopping an electro-desalting drum once a year to clear sludge sedimentation, reduces the number of electro-desalting drum backwashing times, simplifies electro-desalting operations, and improves the electro-desalting effect.
