GAS SCRUBBER FOR REMOVING AMMONIA FROM WASTE GAS

摘要

The present invention relates to a gas scrubber, comprising: a pyrolysis unit which heats waste gas containing ammonia to decompose a portion or the entirety of the ammonia contained in the waste gas into nitrogen and hydrogen; and a combustion unit which injects air into the waste gas passed through the pyrolysis unit to burn the waste gas. The gas scrubber according to the present invention performs a pyrolysis process and a combustion process on the ammonia contained in the waste gas or a mixture of the ammonia and hydrogen without generating waste water, and easily exchanges the heat of the thermal energy of the combustion unit generated during the combustion of the ammonia with the pyrolysis unit.
