There is. Even when a falling discharge type is adopted, since the discharge itself is an unstable phenomenon, in an industrial-scale device, the desired discharge field 7 is formed by using a plurality of pairs of electrodes.

In this case, if each electrode is directly connected to a power source, it may not be possible to perform an even and stable discharge in each discharge gap due to the fact that the state of the fluid to be treated in each discharge gap is not necessarily uniform or due to slight differences in discharge gap length. It's not easy.

Furthermore, there is a risk that the electric current will suddenly increase instantaneously due to the discharge, and the electrodes may be damaged. For this reason, in conventional devices, an electric resistor is interposed in the circuit connecting the electrode and the power source (for example, Japanese Patent Publication No. 54-23147).

Since an electrical resistor is normally provided for each electrode, as the number of electrodes used increases, it is necessary to use a corresponding number of electrical resistors. In addition, during discharge, electricity is consumed by these electrical resistors, but there is also the problem that all of this electrical energy is dissipated as heat and does not contribute to the discharge. Conditions for discharging! As a result of various studies, we found that the flow velocity of the airflow in the discharge gear knob influences the stability of discharge. Heading This is what led to the completion of the present invention.
