As shown in FIGS. 1 and 2, this ceramic filter has gas channels 21 and 22 formed between a large number of porous thin walls 1, and the outlet side of the gas channels 21 is covered with a ceramic sealing material 3. At the same time, the inlet side of the gas flow path 22 is sealed with a ceramic sealing material 4. In this case, the gas flow path 21 whose outlet side is sealed is not sealed at its inlet side, and the gas flow path 2□ which is sealed at its inlet side is not sealed at its outlet side, so that the exhaust gas A is From the channel 21 through the porous thin wall 1 to the gas flow channel 2

, is inserted into the gas flow path 151 on the gas inflow side, that is, on the dust collection side. The electrode 13 is made of the same material and has the same dimensions as the electrode 12, and is inserted into the gas flow path 152 on the gas outlet side. Therefore, the electrode 151
.. 152 are opposed to each other with the porous thin wall 14 interposed therebetween. In this case, the electrodes 12.13 do not all need to be arranged in the gas flow path '5x+152, but may be inserted every other electrode or every other electrode. Further, the electrode 13' arranged in the gas flow path 152 on the gas outlet side is not limited to a thin metal wire, but may also be one in which a porous conductor is arranged along the porous thin wall 14, as shown in FIG. −.

に電圧を印加する。Thus, in the method of the present invention, the exhaust gas A containing fine carbon particles is passed through and the fine carbon particles are mechanically collected by the porous thin wall 14. During this collection, a voltage is applied between the electrodes 12 and 13.

大化するため集塵率が向上する。In this case, the applied voltage is a direct current, an alternating current, or a pulse voltage thereof, and is set to a relatively low voltage that does not cause the carbon particles to become heated and oxidized. By applying a voltage, fine carbon particles are aggregated and coarsened mainly by the action of alternating current, and a deposited dust layer with a thick porosity is formed mainly by the action of direct current. Therefore, since the porosity is large, an increase in pressure drop is prevented, and the particles are aggregated and coarsened, so that the dust collection rate is improved.

、ガ゛ス什する。In this case, the applied voltage is set to a high voltage to generate a streamer discharge, and the carbon particles are oxidized and burned by this discharge, thereby gassing them.
なお、ダスト焼却のだめの高電圧印加は、ガス温度が6

なうのが好ましい。In addition, when applying high voltage to the dust incineration tank, the gas temperature is 6.
It is preferable to carry out the process in synchronization with the temperature when the temperature rises to 00 to 700°C or higher.

In addition to increasing the porosity of the deposited particle layer to improve the dust collection rate, when dust accumulates and the pressure drop increases, the carbon particles are removed using electrical discharge. It has the remarkable effect of preventing incineration, gasification, and clogging, allowing continuous operation for long periods of time.
