The sonic cleaner generates a sound wave with a certain energy to offset the accumulation force or surface adhesion of dirt floating in the air flow to prevent them from combining with each other to form a hard layer. The dust cleaning device is mainly composed of a sound wave generator, a sound conduit and the corresponding pipeline system and control system. It is widely used in various dust removal equipment, storage silos and pipelines in petroleum, chemical, electric power, metallurgy and other industries, as well as in places where dust accumulation, accumulation and poor circulation are easy to occur. It can effectively remove dust and debris on the surface of various dust accumulation bodies. , bridge or block.
The special sonic dust cleaner for the handpiece electrostatic precipitator can loosen the dust accumulated on the surface of the machine head electrostatic precipitator, so that the air flow can take away the dust. Its sound wave frequency is much higher than the resonant frequency of the equipment structure, and will not damage the machine head electrostatic precipitator. Frequently turning on the sonic cleaning device can prevent the machine head electrostatic precipitator from clogging and improve heat exchange efficiency. By rationally arranging acoustic wave cleaning, During the ash cycle, the amount of ash is at a stable low level.
◆ Working Principle
The sonic cleaner uses compressed air as the power source, causing the compressed air to flow through the metal diaphragm and other sound wave generating components to generate specific low-frequency, high-energy sound waves. Resonant propagation in the sound field of the medium causes the dust particles in the gas medium to vibrate synchronously, and periodically changes the longitudinal pressure gradient of the dust boundary layer. Under the repeated cumulative action of acoustic vibration and fatigue, it is difficult for tiny dust particles to approach the dust surface or The dust deposited on the surface of the dust is destroyed and peeled off, thereby achieving the purpose of removing the dust (as shown in Figure 1).
◆ Principle of dust cleaning
Sonic cleaning technology mainly relies on low-frequency sound waves propagating inside the equipment. Through the movement of the sound wave field, the sound wave energy is transmitted to all directions around, and the pulsation is used to accumulate dust, making it Being subjected to alternating pressure and tension, the purpose of dust cleaning is actually achieved by acoustic oscillation and acoustic fatigue. The function of acoustic oscillation is to prevent dust from adhering to the surface of dust-covered objects, and the function of acoustic fatigue is to make the dust adhere to the surface. The dust on the surface of the dusty object is peeled off from the surface of the dusty object through fatigue (as shown in the figure).
◆ Product Features
Sonic cleaning is a preventive cleaning method.
Sonic cleaning is a preventive cleaning method that prevents ash from accumulating on the surface of the machine head electrostatic precipitator, keeps the machine head electrostatic precipitator continuously clean, and achieves the highest heat exchange efficiency.
Sonic cleaning does not have any toxic or side effects on the machine head electrostatic precipitator.
Sonic cleaning does not have any toxic or side effects on the machine head electrostatic precipitator, and long-term operation will not cause corrosion or blockage of the machine head electrostatic precipitator.
Non-contact cleaning method.
The sonic dust cleaner is a non-contact dust cleaning method that does not wear the machine head electrostatic precipitator and can effectively extend the service life of the machine head electrostatic precipitator.
The equipment cost is much lower than that of traditional dust collectors.
The structure of the equipment is simple. Once the sound waves enter the electrostatic precipitator on the machine head, they can automatically propagate to the space where dust removal is required through reflection, diffraction, transmission and refraction. There is no need for large and complex telescopic and rotating mechanisms, so Equipment costs are much lower than traditional dust collectors.
Low operation and maintenance costs.
The sonic cleaner has no rotating parts. The equipment body is made of stainless steel and has a service life of more than one year. The titanium diaphragm of the sounder generally has a service life of more than one year.
No harm to equipment and human health and safety.
The sound wave frequency range avoids the inherent vibration frequency of the machine head electrostatic precipitator equipment structure. The vibration of the equipment structure caused by the sound wave excitation is very small and will not cause mechanical wear.
