Exhaust gas purifying system

A method for purifying exhaust gas of a combustion engine, said method comprising the steps of:

• (a) passing said exhaust gas into an exhaust gas converter chamber;
• (b) cooling said exhaust gas converter chamber by providing a cooling jacket filled with a coolant and enveloping said exhaust gas converter chamber;
• (c) spraying a scrubbing liquid under pressure into a stream of said exhaust gas in said exhaust gas converter chamber for forming a moisture-saturated exhaust gas in order to remove pollutants dispersed in said exhaust gas and purifying said exhaust gas, said moisture-saturated exhaust gas including a waste liquid and a purified exhaust gas in the form of a substantially cleaned air;
• (d) passing said moisture-saturated moisture-saturated exhaust gas from a downstream end of said exhaust gas converter chamber into a primary circulating reservoir;
• and
• (e) separating said purified exhaust gas from said waste liquid and cleaning said scrubbing liquid from said pollutants dispersed in said waste liquid for reuse, said pollutants including a lightweight pollutants float on a surface of said waste liquid in said primary circulating reservoir and a heavyweight pollutants settle by gravity in a lower section of said primary circulating reservoir.

A combustion engine and exhaust discharge pipe in combination with a system for purifying exhaust gas from said combustion engine, said system for purifying exhaust gas comprising:

• a hollow casing;
• an exhaust gas converter chamber disposed with said casing, said exhaust gas converter in fluid communication with said exhaust discharge pipe of said engine for permitting a flow of the exhaust gas through said exhaust gas converter chamber;
• at least one liquid spray nozzle for spraying a scrubbing liquid into said exhaust gas converter chamber for forming a moisture-saturated exhaust gas in order to remove pollutants dispersed in the exhaust gas and purifying the exhaust gas, wherein the moisture-saturated exhaust gas includes a waste liquid and a purified exhaust gas in the form of substantially cleaned air;
• a cooling container disposed within said casing and defining a cooling jacket enveloping said exhaust gas converter chamber, said cooling jacket filled with a coolant to cool said exhaust converter chamber;
• a primary circulating reservoir fluidly connected to said exhaust gas converter chamber for receiving the moisture-saturated exhaust gas for separating the purified exhaust gas from the waste liquid and for cleaning the scrubbing liquid from the pollutants dispersed in the waste liquid for reuse;
• and
• a secondary circulating reservoir fluidly connected to said primary circulating reservoir for receiving the cleaned scrubbing liquid therefrom and supplying the scrubbing liquid to said at least one liquid spray nozzle.
