ULTRASONIC BATH

Designation

The ultrasonic bath is used for treatment of liquids and liquideous substances in ultrasonic fields, as well as of solid surface in liquids under ultrasound.

The bath may be used to prepare suspensions (including those of nanoparticles) or emulsions of different substances, rinsing of small parts from mechanical impurities; extraction and dispersion.

Applications

- chemistry, sonochemicstry;

- acceleration of sonochemical reactions;

- improvement of reactive abilities of metallic surfaces;

- scission of high-molecular compounds (depolymerizing);

- catalytic effect in reactions based on powders (for instance, under ultrasound the catalytic effect of Nickel powder can be intensified by several orders of magnitude);

- cracking of paraffins into minute fragments under room temperature;

- enhancement of the yield rate in Ullmann and Wurtz reactions, as well as in some others.

Medicine:

- fast bacterial breakdown, including such bacteria as Acetobacterxylinum, Actinomyces, Bacillus subtilus, Candida albicans, Erythrozytes, Eukaryotic cells, H. Ep. 2-cells, Helicobacter pylori, Saccharomyces cerecevisae, Lactobacillus, Staphylococcus aureus, Steptococcus;

- cell disruption.

Industrial technologies:

- cleaning and degreasing of surfaces;

- production of stable and fine emulsions;

production of stable and fine suspensions, including nanoparticle suspension;

- degasifying treatment of liquids.

Operation principles

The bath is composed from a container with emitters and a generator.

The emitters are connected to the bath bottom by means of explosive welding, thus ensuring resistance to mechanical effects, increasing the lifetime 10 times, making it possible to use higher sound intensities, and to work with liquids at high temperatures.

The operation principle of the bath is as follows: piezoelectric emitters convert the electrical oscillations, generated by the transistor generator, into elastic mechanical vibrations at a corresponding frequency. These vibrations are transferred to the working medium trough the bath bottom.

The impact on the physico-chemical processes in liquids is achieved mostly by means of secondary acoustic effects, namely cavitation and acoustic flows.
