【 摘 要 】

The article considers parameters of the influence of a high voltage source (HVS), as a form of the output voltage curve and its influence on the technological parameters of the electron-ion technology (EIT) devices for various purposes, the HVS schematic solutions and their classification. A equivalent circuit a single-zone electrostatic precipitator is developed, differing from the existing ones in that the differential capacitance is moved beyond the key VD, because the volume charge can be neglected until the moment of ignition of the corona discharge when considering the corona-discharge system, i.e. for simplicity, the condition is assumed that volumetric charges are created only by corona discharge. Based on this scheme, an equivalent electrical equivalent circuit for a two-zone electrostatic precipitator was constructed. The analytical expression for calculating the electrical constructive capacity of the most commonly used in the electrostatic precipitator corona-discharge system "a number of wires - a plane," taking into account the additional electric capacity. The article presents the results of the investigation of the effect of the frequency of the output voltage of the HVS and the additional capacitance of the capacitor bank on the volt-ampere characteristic of the corona-discharge system of the electrostatic precipitator-ozonizer. The analytical expression is shown in general form, describing the volt-ampere characteristic of the electrostatic precipitator, taking into account the shape of the HVS output voltage curve. An analytical expression for determining the ozone concentration at the output of the EIT devices in the general case is also shown.
