Abstract

Provided is a reflector topological structure-based acoustochemical treatment device for attenuating the standing wave effect. The acoustochemical treatment device includes an acoustochemical reactionvessel, wherein ultrasonic arrays are adhered to a bottom surface A of the acoustochemical reaction vessel and two side surfaces B and C, which are arranged perpendicular to the bottom surface A andintersect the bottom surface A, of the acoustochemical reaction vessel; ultrasonic radiation surfaces are formed by the bottom surface A and the two side surfaces B and C, and reflectors are installedon three ultrasonic reflection surfaces F, D and E which are arranged opposite to the three ultrasonic radiation surfaces A, B and C; the reaction vessel can be made according to the height of the reflector topological structure so as to radiate waves with an integral multiple of a quarter of the wavelength of ultrasonic waves, so that the wave loop of a standing wave which spreads in the direction of the ultrasonic radiation is overlapped with the wave; a liquid level sensor is installed inside the reaction vessel, and a single-chip microcomputer is used for controlling switching valves of aliquid inlet and liquid outlet of the reaction vessel and controlling the volume of reaction liquid in the sealed reaction vessel and the ultrasonic processing time. Through the reflector topologicalstructure-based acoustochemical treatment device for attenuating the standing wave effect, the intensity and distribution of a sound field in the reaction vessel can be improved obviously, the standing wave effect can be attenuated effectively, and the efficient treatment of the reaction liquid or to-be-processed products can be achieved.
