除去するためのメンテナンスを行う必要性が高い。In a gas treatment device, dust in the gas to be treated is charged to the negative pole, and the dust charged to the negative pole is a force corresponding to the electric field strength according to Coulomb's law, as in the electrostatic precipitator. Is attracted to the positive pole discharge electrode and accumulates on the surface of the positive pole discharge electrode.
Aggregate. The dust thus deposited / aggregated on the surface of the linear discharge electrode acts as an electric resistance between the discharge electrodes, and hinders a desired discharge. Further, in the gas treatment device having the linear discharge electrode as the positive electrode, the surface area of the plus electrode is smaller than that of the gas treatment device having the cylindrical discharge electrode as the positive electrode, and therefore, the obstruction due to dust accumulation / aggregation is prevented. It occurs early. Therefore, in a gas treatment device having a linear discharge electrode as a positive electrode, maintenance for removing dust accumulated / aggregated on the discharge electrode is performed as compared with a gas treatment device having a cylindrical discharge electrode as a positive electrode. There is a high need.

なものになる。However, when the dust removing technique of the electrostatic precipitator is adopted as in the above-mentioned conventional technique, the dust removing technique of the electrostatic precipitator requires that the dust collecting / aggregating discharge electrode (that is, the collecting electrode). It is a means to give off the dust by vibrating the discharge electrode by striking the dust electrode) with a hammer, so not only the linear discharge electrode but also the supporting part of the linear impact electrode is shocked to remove the dust. The structure of the discharge cell is complicated because it is easy to cause insulation failure and it is necessary to incorporate mechanical parts such as a hammer and a mechanism for operating it into the discharge cell so as not to disturb the intended discharge. Therefore, maintenance becomes complicated.
