Problems solved by technology
Among them, the high-voltage electrostatic dust removal method has a better dust removal effect, but the electric field must be strengthened externally, and there is also the fact that the adsorbed dust particles accumulate on the dust removal net and cannot be self-cleaning, which affects the dust removal effect.
Dust particles can be effectively removed by activated carbon filtration and adsorption, but there is a problem that the adsorption performance is reduced due to the saturation of the adsorption material, and it is difficult to popularize and use it in large-scale dust removal due to cost issues

The invention discloses an air dust removing method and a dust removal device based on piezoelectric characteristics of a material. A dust removing rod made of a piezoelectric material is fixedly mounted on an insulating support in a dust removing chamber, and dust-containing air is blown from an air inlet to the dust removing rod at a certain pressure, so that the dust removing rod generates an electric field through the material piezoelectric effect to adsorb dust particles in the air so as to achieve the purpose of dust removing and purification on the air, and the air subjected to dust removing and purification is discharged from the air outlet. Through utilizing the characteristic that the piezoelectric material generates mechanical vibration after being subjected to voltage, after the performance of the dust removing rod is reduced, the voltage with a certain frequency is applied to the dust removing rod to enable the dust removing rod to generate mechanical vibration so as to shake off dust particles on the dust removing rod, and the performance of the dust removing rod is recovered. By means of the mode, the dust removing performance can be automatically adjusted, when thedust removing performance is reduced, the dust removing performance can be conveniently and rapidly recovered without replacing dust removing materials, and the dust removing device has very practicalvalue and market application.
Description
technical field [0001] The invention relates to the field of air dust removal and purification methods and dust removal equipment, in particular to a method for air dust removal and purification using piezoelectric characteristics and a dust removal device using piezoelectric characteristics. Background technique [0002] With the rapid development of my country's economy and the excessive development of environmental resources by human beings, the natural environment continues to deteriorate and air pollution is serious, especially some harmful particles in the air, which have caused serious damage to people's lives and health. At present, in order to control the emission of particulate matter in my country, in addition to measures such as strengthening legislation and standardizing production, there is still a lack of effective and economically feasible methods for removing dust particles. [0003] At present, the common methods of air dust removal include dry dust removal...
