PURPOSE: A post treatment equipment of exhaust gas is provided, which can completely remove harmful matter contained in exhaust gas by using plasma discharge. The system can also increase purifying efficiency by reducing soot accumulation that causes insulation breakage between anode and cathode. CONSTITUTION: The post treatment equipment comprises a plasma generator(2); a sealed outer housing(4) which is electrically connected to each positive and negative poles of the plasma generator, and an exhaust gas inlet(4a) and an exhaust gas outlet(4b) are respectively formed thereto; a cathode bar(12) which is electrically connected to the negative pole of the plasma generator, and installed along the central axis inside the sealed outer housing; a plurality of primary separators(14) which are installed at the cathode bar to compartment inner space of the sealed outer housing; a perforated cylindrical cathode(16) which is supportingly connected to the primary separator, and exhaust gas passes through a plurality holes formed thereon; a plurality of pin electrodes(18) which are installed at the center of every hole formed on the perforated cylindrical cathode to be electrically connected; a perforated cylindrical anode(6) which is supportingly connected to a secondary separator(8) inwardly installed against the sealed outer housing, and exhaust gas passes through a plurality holes correspondingly formed to holes of the perforated cylindrical cathode.
