炭を無害化する設備が別途必要であった。2. Description of the Related Art Heretofore, several organic halogen compound decomposition treatment apparatuses are known. FIG. 3 shows an example. In this solvent recovery apparatus, the activated carbon layer 101 is filled with activated carbon 102, and exhaust gas containing an organic halogen compound is passed through the activated carbon layer 101. Thus, the organic halogen compound was adsorbed on the activated carbon 102. However, in this solvent recovery apparatus, the recovery amount is determined by the equilibrium adsorption amount between the activated carbon and the organic halogen compound, and thus the recovery amount is limited. In addition, since the operating temperature is usually set to a low temperature, energy efficiency is low. Further, equipment for detoxifying the activated carbon containing the collected organic halogen compound was separately required.

That is, the organic halogen compound is treated by passing exhaust gas containing the organic halogen compound through the combustion furnace 201. However, if halogens are present in the molecule, it becomes difficult to burn, so a very high temperature is required for processing, and if necessary, an auxiliary material such as methane is required, which tends to deteriorate energy efficiency. there were.

The alternating voltage applied to the pellet filling layer 5 between 7 causes polarization between the pellets constituting the dielectric 6. As a result, a very high electric field strength is obtained in the vicinity of the pellet, and plasma is generated in a gap between the pellets.
This plasma is a non-equilibrium plasma, and ions having a large mass are not accelerated by an electric field, and only electrons having a small mass are accelerated by an electric field to obtain high energy. Radicals are generated from oxygen and the like in the air by the action of this plasma, and the aerated organic halogen compounds are decomposed by such molecular species. As described above, most of the input energy is used only for accelerating the electrons that contribute to the decomposition of the organic halogen compound, so that the energy efficiency is high. And these actions occur at normal temperature under atmospheric pressure.
That is, the organic halogen compound decomposition treatment apparatus according to the present invention can process an organic halogen compound at room temperature and has high energy efficiency.
