Tubular ultrasonic separation cavity

Abstract

The invention relates to a tubular ultrasonic separation cavity. The tubular ultrasonic separation cavity comprises a columnar ultrasonic vibration source and a tubular reflector, and is characterized in that the columnar ultrasonic vibration source is arranged in the tubular reflector, an annular cavity is formed between the columnar ultrasonic vibration source and the tubular reflector, and an acoustic reflection material is arranged on the inner wall of the tubular reflector. By the arrangement of the tubular ultrasonic separation cavity, the defects of a traditional solid-liquid separation method are overcome, for example, the problem of filter screen blockage in a filtration method is solved; the problem of low treatment capacity of an existing ultrasonic solid-liquid separation device is solved, and thus the industrial application range of the ultrasonic solid-liquid separation technology is further broadened.

Description

technical field [0001] The invention relates to a tubular ultrasonic separation chamber. Background technique [0002] In many industrial applications, the concentration or separation of suspended matter in fluid media is an important and indispensable process, and methods that can achieve concentration or separation of suspended matter, such as filtration, sedimentation, centrifugal separation and coagulation, It has been relatively mature application in many industrial fields. However, with the advancement of science and the continuous expansion of people's practice fields, the inherent defects of traditional methods have greatly restricted their application range, such as the filter method is prone to blockage of the filter, and the coagulation treatment is likely to cause secondary pollution. [0003] The use of ultrasound for the concentration or separation of suspended matter in fluid media was proposed in the 1930s. Ultrasonic concentration or separation technology h...

AI Technical Summary

Problems solved by technology

[0004] Due to the limitation of size and the influence of acoustic flow, the processing capacity of micro-nano-scale ultrasonic concentration or separation devices is greatly limited

In the conventional size range, ultrasonic concentration or separation technology also has certain applications, but either discontinuous processing, or the processing capacity cannot meet the demand

In the high-frequency ultrasonic range, it is mainly limited by acoustic flow and sound attenuation, and the size of the device cannot be excessively increased; in the low-frequency ultrasonic range, it is mainly limited by acoustic cavitation, and the acoustic energy density of the fluid medium cannot be excessively increased, thereby affecting Processing efficiency
