Only the exhaust gas 2 that has passed through the porous thin wall 6 that defines each flow path 5 is discharged to the downstream side, and particulates are collected on the inner surface of the porous thin wall 6. It is made to be done.

- Patent Document 1 The prior art documents relating to the plasma-assisted exhaust gas purification apparatus are also disclosed in, for example, Patent Document 1 below.
- Patent Document 1 Japanese Patent Publication No. 2002-501813
- the conventional plasma-assisted exhaust gas purification apparatus requires a large amount of electric power to regenerate the particulate filter 4, so that the existing vehicle battery cannot provide enough power. Therefore, there is a problem that the fuel consumption becomes poor because a large-capacity power supply is required, and the power needs to be charged according to the consumed power.
- the particulate filter 4 when the particulate filter 4 is regenerated, the particulates are incinerated at a relatively low temperature, and there is a concern that harmful gases such as high-concentration CO and HC are generated and are discharged into the atmosphere. there were.
- the present invention has been made in view of the above-described circumstances, and provides a plasma-assisted exhaust gas purification apparatus that requires less power consumption and does not discharge harmful gases into the atmosphere. It is an object.
- the present invention provides a filter main body made of a porous material that allows exhaust gas to pass therethrough and captures particulates in the exhaust gas, with an electrode capable of generating plasma inside the filter main body.

- the exhaust gas flowing into the filter case can cause the exhaust gas of the preceding stage to become exhausted.
- NO which accounts for the majority of NOx in the exhaust gas, becomes highly reactive NO.
- the filter body is installed when it is estimated that the amount of accumulated particulates is equal to or greater than a predetermined amount (it is sufficient to estimate from the pressure difference between the inlet and outlet sides of the filter body and the operating time). A voltage is applied between the electrodes to discharge inside the filter body.
- the plasma regenerating type particulate filter is divided into a plurality of small filters, and is installed in parallel in the filter case, and a discharge voltage is individually applied to each small unit. It is preferred to be configured to be able to.
- the plasma regeneration type particulate filter can be individually regenerated by the plasma for each small unit, so that it is possible to sufficiently cope with a relatively small power supply.
- the power is also divided into multiple small units, so the unit is As a result, the combustion of the particulates at the engine is improved, and the regeneration by the plasma when the engine is stopped in a vehicle equipped with an idle stop device is also realized.
- the oxidation catalyst is integrally supported on the porous material constituting the filter main body, so that the oxidation of the particulates collected in the filter main body can be achieved.
- the reaction is accelerated, the ignition temperature is lowered, the exhaust temperature is low, and the flammability of the particulates in the operating state is further improved, so that better combustion and removal of the particulates are realized.
- a large number of channels through which exhaust gas flows are formed in a honeycomb shape, and the inlet and outlet ends of each channel are alternately examined. It is possible to use a sealed filter body, and furthermore, when such a filter body is used, a rod-shaped electrode is inserted into the axis of the filter body and a cylindrical shape is formed on the outer peripheral surface of the filter body. It is good to attach electrodes.
- the risk that harmful gas remains in the gas can be avoided beforehand.

NO, which accounts for the majority of NOx, becomes highly reactive NO, and under operating conditions where the exhaust gas temperature is about 250 ° C or higher.
- the oxidation reaction of the particulates is greatly promoted, and the particles are favorably burned off.
- the acid reaction of the particulates trapped in the filter body 7 is promoted by the exhaust gas excitation component, and the particulates are satisfactorily burned and removed even under an operating condition at a low exhaust temperature.

- the temperature of the filter body 7 rises rapidly, which makes it easier to burn the particulates.As a result, the burning of the particulates can be completed in a shorter discharge time than before, and the power consumption is reduced. Will require less Further, since the voltage is individually applied to each of the small units 11 A, 11 B, 11 C, and 1 ID of the plasma regeneration type particulate filter 11 to discharge, a relatively small-capacity power supply 14 is sufficient.
- the force is also divided into a plurality of small units 11A, 11B, 11C, 11D, so that the flammability of particulates in each unit becomes good, and as a result, in vehicles such as those equipped with an idle stop device Regeneration by plasma when the engine is stopped is also realized.
- the particulate matter collected in the filter body 7 is effectively burned with the assistance of the plasma.
- the filter body 7 can be quickly heated by the heat retention effect of the front and rear oxidation catalysts 16 and 17 to create an environment where particulates can be easily incinerated. The burning and removal of the particulates can be completed in the discharge time, and the power consumption can be greatly reduced.
- harmful gases such as high-concentration CO and HC generated by burning the particulates at a relatively low temperature with the help of plasma are passed through the subsequent oxidation catalyst 17 to remove harmful CO and HC. It can be discharged to HO by acid treatment and finally discharged to the atmosphere.
- the risk of harmful gases remaining in the outgoing gas 2 can be avoided beforehand.
- the plasma regenerating particulate filter 11 is divided into a plurality of small units 11A, 11B, 11C and 11D and installed in the filter case 12 in parallel.
- a relatively small-capacity power supply 14 can be used sufficiently. This makes it possible to realize regeneration by plasma when the engine is stopped in vehicles equipped with an idle stop device.
