IMPROVEMENT OF CAVITATION HEAT GENERATOR DESIGN

Abstract

The main problems in the heat industry for many years remain low energy efficiency, reliability and inefficiency of thermal energy devices. Widespread use of electricity for electrification of thermal processes is not always determined by a competent solution for the use of electric heating, which does not allow to obtain the maximum economic effect. The solution of this issue has been in the center of attention of heat and energy specialists for a long time. However, their approaches to improving the energy efficiency of engineering systems differ significantly.
Scientific and technological progress is determined by the development of high technologies, which provide, on the one hand, the production of new materials and products, and on the other - reduce energy and resource consumption, increase environmental performance. One of the devices, the operation of which is based on the new principle of obtaining thermal energy, is a cavitation heat generator. Cavitation heat generator - a special device that uses the effect of heating the liquid by cavitation. That is, it is an effect in which microscopic vapor bubbles are formed in areas of local reduction of water pressure. Recently, the production of such units is mastered by many manufacturers and they are increasingly appearing on the domestic market. In order to make a technological breakthrough in this area - it is necessary to dramatically reduce electricity losses in known cavitation heat generators. Unlike traditional technologies of cavitation bubbles based on continuous power consumption, electropulse technology allows to increase the parameters of electrical influences (field strength, current density, instantaneous power) and, consequently, significantly intensify processes, reduce energy consumption.
