Patent ID: 8414289

Claim:
A whirlwind-type oxidation combustion apparatus for processing a semiconductor fabrication exhaust gas, an inlet head being set in between an exhaust gas supply terminal and a combustion gas supply terminal, the inlet head being located on the top of an exhaust gas processing tank, an outer water screen forming on the inner wall of the exhaust gas processing tank, the inlet head comprising: an exhaust gas passage, interconnecting the exhaust gas supply terminal and the exhaust gas processing tank, for guiding the exhaust gas into the exhaust gas processing tank; an upper partition and a lower partition, lying in between the surrounding of the exhaust gas passage and the inner wall of the inlet head, an ignition chamber being formed in between the surrounding of the exhaust gas passage, the inner wall of the inlet head, and the upper and lower partitions; a plurality of upper inclined holes, scattering in a vortex pattern on the upper partition and encircling the surrounding of the exhaust gas passage, the upper inclined holes interconnecting the combustion gas supply terminal and the ignition chamber and guiding the combustion gas to swirl into the ignition chamber; an igniter planted in the ignition chamber, for igniting the combustion gas in the ignition chamber to form a vortex flame to heat up the exhaust gas in the exhaust gas passage; and a plurality of lower inclined holes, scattering in a vortex pattern on the lower partition and encircling the surrounding of the exhaust gas passage, the lower inclined holes interconnecting the ignition chamber and the exhaust gas processing tank, the lower inclined holes guiding the flame to swirl into the exhaust gas processing tank to combust the exhaust gas entered from the exhaust gas passage into the exhaust gas processing tank, the lower inclined holes further causing the exhaust gas to swirl onto the water screen.
