Issues of technological processes’ intensification and increase of technological equipment efficiency are of priority value in the modern engineering. Application of various methods of hydrodynamic drag on the working fluids in rotary-wheel machines allows increasing of processing efficiency to receive finely-dispersed homogeneous mixtures with necessary characteristics. In this article the issues, connected with the liquid flows' formation in the working zone of rotary-cavitating activator are studied and the main principles of energy impact while the usage of rotor with radial channels, supplied with the elements for receiving cavitating effects, are defined. Based on the offered methodology, experimental research was conducted and calculations of the main indexes, defining efficiency of energy impact on the working medium, were held. The substantiated estimation of efficiency of hydrodynamic machines work according to the dissipative power that allows to choose the proportion of hydrodynamic settings, which provide the highest intensity of cavitating processing of processed liquids, was presented. The practical value of the research is in the studying of ways of increasing of equipment efficiency through the possibility of technological process intensification.

In Europe, 3 % of the electricity consumed by industry is spent on the production of compressed air. At the same time, the payment for electricity consumed by the compressor is the largest share in the structure of the factorys costs. In modern production, compressed air requires drying to meet the requirements of the equipment and for various technological processes. In this case, a large amount of compressed air is lost thus, improving the design of air dryers is an important step for improving energy efficiency. In this paper is developing a method for reducing the energy costs of the heated desiccant dryers is developed by mean of regenerating adsorbents using microwave energy.In the process of developing heaters using microwave energy, the main problem is the achievement of a uniform heating of the material. The same problem also arises when using microwave energy to regenerate the adsorbent in the adsorption dryer. Due of above-mentioned, the problem by dynamically changing the configuration of the heater chamber and waveguide systems is solved by using of increasing the uniformity of heating and two opposite waveguides in the heater design with a variable phase of one of them. A specific condition for conducting experiments is obtained. Particularly the adsorption dryer chamber is a cylindrical vessel that is filled with an adsorbent and has predetermined proportions. A significant change of these proportions adversely affect at the adsorption process during the operation of the desiccant.

Energy conservation issues are acute in the world. Compressed air is widely used in the modern industrial production. The production of compressed air is a very energy-intensive process, since most of the energy, which is expended by the compressor, passes into the energy of heating. Compressed air cannot be used in modern production without a prior drying and cleaning. Industrial dryer’s air losses is up to 20% of compressed air additionally. Therefore, the issue of saving air during its drying stage is important. In the presented article, the thermal and aerodynamic processes that occur in the classical adsorption tower with the most modern design are considered. The processes that occur in the adsorption column with the microwave regeneration of the adsorbent are also considered. A comparative analysis of these constructions from the point of view of energy saving is made.
