量を得ることができない。SUMMARY OF THE INVENTION The conventional apparatus described above has the following drawbacks, making it difficult to put it into practical use. (1) Exhaust gas processing amount per electrode set is 100l/mi
n, 100 sets of electrodes are required to obtain a processing capacity of 10,000 l/min. Although alternating current power is used to generate plasma, if there are variations in the capacitance of the electrodes (caused by the temperature distribution of the gas, differences in electrode spacing, etc.), the plasma power of each electrode will become non-uniform. Therefore, with 100 pairs of electrodes, the flow rate is 10,000 l/m.
When it becomes in, NOX, N2 due to plasma non-uniformity
The reduction rate of O and SOX decreases, making it impossible to obtain a satisfactory throughput. (2) In the case of one set of electrodes, increasing the power by increasing the voltage or frequency of the plasma power source improves the reduction rate of NOX, N2O, and SOX, and increases the throughput. However, in the case of 100 pairs of electrodes, when the plasma of each electrode is non-uniform as described in (1) above, increasing the voltage and frequency will further exacerbate the non-uniformity of the power of each electrode. Ru. Therefore, even if an attempt is made to increase the throughput by connecting a plurality of electrodes in parallel, the reduction rate decreases, making it impossible to obtain a satisfactory throughput.

2 O and SOX are activated and rendered harmless. At this time, the plasma power increases with the high frequency component of the applied composite wave voltage, and the removal rate of NOX, N2O, and SOX improves. Further, the low frequency component suppresses power non-uniformity due to capacitance variation between pairs of opposing flat plate electrodes and sawtooth electrodes. As a result, the electric power between each group becomes uniform, and a large amount of exhaust gas can be treated.

力で供給することができる。Since a plurality of electrodes are connected in parallel, the lower the frequency of the applied voltage, the less the influence of variations in capacitance of each electrode, and uniform plasma power is supplied to each electrode. In this respect, it is sufficient to set the applied voltage so that the electron energy of the plasma becomes 9.5 eV with a low frequency voltage. However, at lower frequencies the power is lower;
In particular, the N2O removal effect decreases. On the other hand, if the frequency is increased to improve the N2O removal effect, non-uniformity in plasma power due to variations in the capacitance of each electrode will be promoted, and the throughput across multiple electrode sets will be reduced. . Therefore, as shown in Figure 3(c), by combining high-frequency voltage and low-frequency voltage, that is, by using an AC voltage in which high frequency is modulated by low frequency, the low frequency component suppresses the non-uniformity of plasma power at each electrode. , high frequency can be supplied to each electrode with uniform power.
