Abstract

See full text

Provided is an apparatus for treating waste gas of the electronics industry, and the apparatus includes: a reaction chamber in which an inlet and an outlet are formed and an inner space for purifying waste gas is formed; a first partition plate extending from an inner wall of the reaction chamber facing the inlet in a direction toward the inlet, dividing the inner space into a pre-treatment zone for collecting dust in the waste gas and a remaining purification zone; a second partition plate extending vertically downward from a ceiling of the reaction chamber, dividing the purification zone into a thermal decomposition zone for heating and thermally decomposing waste gas and a post-treatment zone; and a heater installed at the ceiling of the reaction chamber so as to be located in the thermal decomposition zone to thermally decompose a perfluorinated compound by heating waste gas introduced into the thermal decomposition zone; and a dry scrubber unit including one or more catalysts to collect at least one of the dust, a fluorine compound, and nitrous oxide (N2O) in waste gas introduced into the post-treatment zone.
