Thanks to a new ultrasound method, material defects can now be displayed in three dimensions.

Ultrasound Application In Air Purification

Ultrasound is used in a wide array of non-standard treatment cases based on other physical principles of action. Such manufacturers like Hilsonic provide an opportunity of building custom ultrasound solutions and ultrasonic cleaner equipment in particular, allowing businesses and governmental organisations solve the most sophisticated tasks.

One of the major technical problems of today is the purification of polluted air from dust, smoke, fumes, mists, metal oxides, and so on. The smallest particles of matter from factory chimneys factory direct upwards, and then carried by wind over long distances. For example, the gray-fly on the leaves of trees and on surrounding objects is the sign of a cement plant somewhere around. Thousands of tons of cement plants exhale the smallest particles sputtered during firing. The same thing happens on the chemical, alabaster, gas and other enterprises.

So is this this problem solvable? For a long time technologists have been using the dust collecting units, which operation is based on different principles, consisting of dust chamber, rotary dust collectors, centrifugal separators, electrostatic precipitators, and so on. However, all these devices are cumbersome and not always effective enough. Therefore, scientists continue to look for new ways to speed up and improve the quality of air purification and gas pollution. Since 1967 symposium in Poland, scientists are working on reducing air pollution. Some scholars are noting in their reports promising ultrasonic method of air purification, due to an extensive set of noteworthy features. It does not depend on the temperature and humidity environment and can be easily automated as ultrasonic devices are totally easy to use.

To deal with air pollution issues a control device that has been gathering dust in a clever way has been discovered. Its action is based on the ability of sound and, in particular, ultrasonic waves affect the tiny particles of dust. So if equipped smokestacks ultrasonic sirens, they will affect the solids smoke besiege in certain places and prevent their spread.


What is the essence of ultrasonic cleaning the air? Dust that randomly fly in the air, under the influence of ultrasonic vibrations more and more collide with each other. As a result, they coalesce and increase in size. The process of enlargement of particles called coagulation. Enlarged particles settle faster, easier captured by conventional filters and, therefore, better to clean the air.

Ultrasonic cleaning methods of air pollution are now implemented in many industries, and get constantly being improved. Experts believe that establishing multi-ultrasonic dust precipitators, and powerful, yet fuel-efficient power supplies is a totally cost-effective solution that pays for itself in the long run. Perhaps, the only fact that the currently slows down the development of the niche is a relatively high power consumption. Therefore acoustic precipitators are mostly used for collecting very valuable and fine dust, such as lead and bronze smelting plants.
