ABSTRACT:
An exhaust gas purifying system and a method for purifying exhaust gas of combustion engines. The system includes a hollow casing, a converter chamber disposed within the casing, spray nozzles for spraying a scrubbing liquid into the converter chamber for forming a moisture-saturated exhaust gas in order to remove pollutants dispersed in the exhaust gas and purifying the exhaust gas, a cooling container disposed within the casing and defining a cooling jacket enveloping the converter chamber for cooling thereof, a primary circulating reservoir fluidly connected to the converter chamber for receiving the moisture-saturated exhaust gas and separating the purified exhaust gas from a 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 the primary circulating reservoir for receiving the cleaned scrubbing liquid and supplying the scrubbing liquid to the liquid spray nozzles.
