The present invention relates to a dust collection and incineration device that collects and incinerates fine carbon particles contained in exhaust gas and the like. Diesel engine exhaust gas contains gas-phase deposited carbon particles, and most of these particles are
It is minute, less than 1μ. For this reason, a ceramic filter having fine pores is used as a dust collector for this exhaust gas. As shown in FIGS. 1 and 2, this ceramic filter has gas channels 2 1 and 2 2 formed between a large number of porous thin walls 1, and the outlet side of the gas channels 2 1 is sealed with ceramic plugs. 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 2 1 whose outlet side is sealed is not sealed at its inlet side, and the gas flow path 2 2 whose inlet side is sealed is not sealed at its outlet side, so that the exhaust gas A is 1 through the porous thin wall 1 and into the gas flow path 2 2 . This ceramic filter collects and purifies the exhaust gas A when it passes through the porous thin wall 1, but since it is a mechanical purification method, it quickly becomes clogged, resulting in extremely high pressure loss. For this reason, there is a problem that it cannot withstand long-term use. The present invention was made in view of the above circumstances, and
The purpose is to incinerate and gasify accumulated dust using arc discharge.
The purpose is to obtain a dust collection and incineration device that can be operated continuously for a long period of time. That is, the present invention arranges a plurality of electrodes for arc discharge at intervals on the dust collection side surface of an insulating porous filter that collects dust by passing a dust-containing gas,
This dust collection and incineration device is characterized in that a pulsed high voltage is applied between electrodes at both ends, and the collected dust is incinerated by arc discharge. The present invention will be described below with reference to illustrative embodiments. FIG. 3 is a schematic sectional view of the dust collection and incineration device according to the present invention. This device includes an insulating porous filter 11, a plurality of rod-shaped electrodes 12, and a plurality of rod-shaped conductors 20. This filter 11
has a structure similar to that shown in FIGS. 1 and 2, with gas channels 14 1 ,
14 2 , and ceramic sealing materials 15 , 16 are provided on the outlet and inlet sides of the gas channels 14 1 , 14 2 .
is provided so that the exhaust gas A flows from the gas flow path 14 1 through the porous thin wall 13 into the gas flow path 14 2 . Examples of its structure include those shown in Table 1 below.

, that is, the dust collecting side surface of the insulating porous filter 11, are arranged at intervals on both ends and upper and lower surfaces by baking or the like. Further, conductors 20 made of the same material as the electrodes are arranged between the electrodes 12 at predetermined pitches. In this case, the width a of the conductor 20 is approximately 0.5 to 2 mm to ensure good arc discharge, and the interval d is approximately 0.5 to 2 mm.
The thickness is preferably about 0.5 to 5 mm. Note that a porous metal plate 17 that allows gas to pass through may be provided on the back surface of the insulating porous filter 11, as shown in FIG. When exhaust gas A containing carbon particles is passed through this dust collection and incineration device, the carbon particles are mechanically collected by the porous thin wall 13. The collected carbon particles C are deposited in the gap between the electrode 12 and the conductor 20 that are adjacent to each other in the left-right direction of the drawing, and between the conductors 20, as shown in FIG. A certain amount accumulates,
When a pressure loss begins to occur, a voltage is applied between the electrodes 12 at both ends. The applied voltage is a pulse voltage or an alternating pulse voltage, and is preferably about several kV to about 10 kV. By depositing carbon particles C in the gap between the electrodes 12, the lower electrode 12 and the conductor 2
0, and the upper electrode 12 and the conductor 20 are electrically connected, so if a voltage is applied at this time, a pulsed arc discharge occurs on the surface of the electrode and conductor adjacent in the left and right direction of the drawing. .
Then, the collected carbon particles are oxidized (burned) and gasified by arc discharge. Note that it is more effective to apply the pulse voltage in synchronization with the rise in exhaust gas temperature (approximately 600°C to 700°C). In addition, a fifth porous metal plate 17 is placed on the back side.
When provided as shown in the figure, a capacitance is formed between the electrode 12 and the pulsed arc can be propagated more reliably. As explained above, according to the present invention, when dust accumulates to a certain extent and the pressure drop increases, arc discharge occurs, incineration, and gasification occur, resulting in the remarkable effect of being able to operate continuously for a long time. play.
