An apparatus for treating gaseous pollutants includes a gas inlet part, a first treatment unit, a second treatment unit and a non-mechanical flow-guiding device. The gas inlet part includes a gas inlet chamber and at least one guide pipe. The guide pipe communicates with the gas inlet chamber and guides an effluent stream from a semiconductor process to the gas inlet chamber. The first treatment unit is coupled to a bottom end of the gas inlet part and is configured to abate the effluent stream. The non-mechanical flow-guiding device is coupled to the first treatment unit. The flow-guiding device is configured to guide the effluent stream to move toward an opening. The second treatment unit is coupled to the flow-guiding device via the opening, receives the effluent stream from the first treatment unit and further abates the effluent stream.
EFFLUENT GAS TREATMENT APPARATUS
Apparatus and methods are disclosed. The apparatus comprises: an abatement chamber of an abatement apparatus which treats an effluent stream from a semiconductor processing tool to provide a combusted effluent stream having effluent particles; and a first atomiser located downstream of the abatement chamber, the first atomiser being configured to produce droplets having a droplet size based on a particle size of the effluent particles to be removed from the combusted effluent stream. In this way, the atomizer may produce droplets which combine with or adhere to the effluent particles which assists in the removal of the effluent particles from the combusted effluent stream.
CATALYTIC DECOMPOSITION DEVICE AND INTEGRATED WASTE GAS TREATMENT SYSTEM
An integrated waste gas treatment system includes an adsorption/desorption device that receives a waste gas that includes an organic compound and an organic nitrogen compound exhausted from a semiconductor manufacturing facility, where the adsorption/desorption device adsorbs the organic compound and the organic nitrogen compound and concentrates and desorbs the organic compound and the organic nitrogen compound, and a catalytic decomposition device disposed adjacent to the adsorption/desorption device, where the catalytic decomposition device includes a catalytic chamber that provides a gas passage through which a gas desorbed from the adsorption/desorption device flows and an oxidation-reduction catalyst disposed in the gas passage that removes the organic compound and the organic nitrogen compound from the desorbed gas. The organic compound and the organic nitrogen compound are subjected to an oxidation treatment by the oxidation-reduction catalyst, and nitrogen oxides generated by the oxidation treatment are removed by a selective reduction reaction.
