Abstract

In connection with the rapid development of high-voltage pulse technology, the phenomenon of electrical breakdown in a liquid is of increasing interest. Depending on the purpose of the installation, the working chamber can have various sizes and shapes. To process the waste of pig-breeding complexes, we have developed an electropulse installation, the working chamber of which has a cylindrical shape, which allows us to simplify the modeling of processes that will occur during the breakdown of liquid in the chamber. The nature and sequence of the discharge processes of the installation depends on such parameters as the state of the electrodes, their shape of exacerbation, the length of the interelectrode gap, the viscosity of the liquid in the chamber, and the presence of impurities. The use of a high-voltage spark as a “working tool” became the first stage of a complex technological process in which a liquid-insulating working medium. The article gives a generalized scheme of the experimental setup, the questions of mathematical modeling of the optimal operating modes of the electric pulse installation are considered. The features of constructing a mathematical model of the electropulse conversion of energy in liquid are considered. Considerable attention is paid to the process of operation of an electric pulse installation, where the current technological mechanism is pressure pulses that emit in the channel of high voltage discharges in an organic liquid. The effectiveness of the impact of pulses is spatially limited and decreases sharply with increasing distance from the axis of the channel and therefore it must be adjusted during the processing of the liquid. In the calculation mathematical model it is necessary to take into account factors affecting the parameters of the pressure pulse in the liquid and the position of the electrodes in space. The article presents the equations of a linearized mathematical model of the processes that occur in the discharge channel of the working body of the electric pulse installation.
