APPARATUS FOR ULTRASONIC PROCESSING OF DISPERSED MATERIAL IN FLUID Russian patent published in 2012 - IPC B03B5/62 B08B3/12 

FIELD: process engineering.

SUBSTANCE: invention relates to cleaning of dispersed materials of impurities in fluid flow. Proposed apparatus comprises cylindrical casing with reagent feed branch pipes arranged at different height, conical part arranged under cylindrical casing and discharge branch pipe. Cylindrical section with initial material feed branch pipe is arranged above cylindrical casing and provided with slime discharge cavities arranged concentrically over its height. Additionally, reagent feed branch pipes are arranged in said conical part. Perforated nozzles are arranged inside cylindrical casing distributed over its height while ultrasound transmitters are secured on its outer surface. Conical an cylindrical sections are acoustically isolated from cylindrical casing that makes resonant cavity of ultrasonic oscillations. Reagent feed branch pipes and perforated nozzles are arranged inside cylindrical casing so that, at preset reagent feed pressure, reagents are fed in counter-current with flow of material being cleaned.

EFFECT: higher efficiency, reduced consumption of reagents.
