Exhaust gas purification system

An exhaust gas purification system for purifying exhaust gas including odor and oil content, comprising:

• a purification exhaust gas passage for transporting the exhaust gas including the odor and the oil content;
• a shower nozzle for dispersing liquid toward the exhaust gas from an upper portion of the exhaust gas transported by the purification exhaust gas passage;
• a tank for storing the liquid dispersed from the shower nozzle;
• a liquid-supply pipe conduit connected between the tank and the shower nozzle for supplying the liquid in the tank to the shower nozzle using a pump;
• and
• an aeration device for supplying gas including oxygen to the liquid in the tank and for oxidatively decomposing organic material included in the exhaust gas;
• wherein
• the shower nozzle disperses the liquid toward the exhaust gas from the upper portion of the exhaust gas, the dispersed liquid is mixed with the exhaust gas and thereafter, the liquid is accumulated in the tank, the odor and the oil content are dissolved by action of microorganism included in the liquid in the tank,
• the shower nozzle is connected to an opening horizontally provided in a nozzle pipe connected to the liquid-supply pipe conduit, the shower nozzle includes a nozzle which is directed in a dispersing downward direction of the liquid, and the shower nozzle is placed in the nozzle pipe such that a lower end of the nozzle is located higher than a bottom of an inner wall of a pipe conduit of the nozzle pipe.
