An Oblique Incidence Ultrasonic Standing Wave Dynamic Scanning Dusty Air Purification Device

Abstract

The invention relates to an obliquely incident ultrasonic standing wave dynamic scanning dusty air purification device, which includes an air supply pipeline, an ultrasonic standing wave system and an atomization system. Wave incident section, spray condensation section and air outlet section; above the ultrasonic standing wave incident section, an ultrasonic standing wave system is arranged obliquely, and the ultrasonic standing wave system is used to emit ultrasonic waves, so that ultrasonic waves can The ultrasonic standing wave field is formed after reciprocating reflections on the upper and lower planes of the pipeline are superimposed; the ultrasonic system realizes moving up and down the standing wave plane formed in the air supply pipeline by continuously adjusting the incident angle of the ultrasonic waves in real time; the atomization system is set In the spray condensation section, it is used to form mist droplets in the spray condensation section, so that the air fine particles can be efficiently condensed and settled in the ultrasonic standing wave field. The invention improves the agglomeration effect of ultrasonic standing waves combined with mist droplets on fine particles, and enhances the purification ability of dusty airflow.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an oblique incident ultrasonic standing wave dynamic scanning dusty air purification device. Background technique [0002] According to relevant studies, particulate pollutants in the air—especially fine particles with a particle size less than or equal to 2.5 μm—not only pose a great threat to human health, but also can cause serious damage in high-tech fields such as chip manufacturing and precision instruments. How to efficiently and energy-savingly remove fine particle pollutants in air-conditioning supply air has always been a technical difficulty. At present, the common purification methods in air conditioning systems, such as filtration and electrostatic dust removal, have been applied, but due to their respective technical characteristics, their optimal use conditions are different, and there are obvious technical limitations. For example, the filter technology ...

AI Technical Summary

Problems solved by technology

[0004] But at present, the technology of acoustic agglomeration to purify air still has obvious deficiencies, because most of the airflow carrying fine particle pollutants does not actually pass through a fixed standing wave layer and cannot be reunited, and its actual purification effect is relatively weak. It is generally believed that the cause is caused by the original performance of sound waves

However, the inventors of the present invention have found that the weaker reason for the above-mentioned effect is because the commonly used ultrasonic wave is a fixed emission angle, and in the layered steady-state ultrasonic standing wave, only the particles in the fixed ultrasonic standing wave layer have an agglomeration effect. However, the technology to realize the purification of the dust-laden airflow in the air supply pipeline without dead ends has not been reported yet.
