Prospects for the use of cavitation mechanisms in order to reduce the consumption of natural water in municipal energy

The paper discusses the existing methods of neutralizing condensate among which the most effective method of hydrodynamic cavitation is determined. To implement the effects of hydrodynamic cavitation, it is proposed to use the way of discrete - pulsed energy input, which allows neutralization by degassing condensate of natural gas combustion products. Based on the created universal mathematical models of the dynamics of single steam-gas bubbles and the ensemble of bubble dynamics, numerical modeling of the growth of steam-gas bubbles in condensate was carried out. Within the framework of the mathematical model of the dynamics of the ensemble of bubbles, an analytical study of the evolution of the unit of steam-gas bubbles to achieve a critical value of the gas content in them was carried out. It has been experimentally proven, the effectiveness of the proposed method, in particular, has been established that the main amount of carbonic acid from both flue gas condensate and model liquid is removed within two minutes of processing. The obtained data prove that an increase in the pH of the treated condensate corresponds to the pH of distillate, which indicates the complete removal of carbonic acid. The implementation of the proposed method of neutralizing condensate will create conditions for improving the environment. This is achieved by reducing the amount of effluent and rational use of water resources by reducing the need for natural water.
