Abstract:
1. Manufacturing equipment comprising a reaction chamber in which a process producing exhaust gas containing perfluorinated compounds (PFCs) is executed, and a system for processing the perfluorinated compounds (PFCs), the system comprising: a pumping unit connected to an outlet of the reaction chamber and comprising a pump that pumps out the gas containing the PFCs from the reaction chamber; a decomposition apparatus connected to the pumping unit so as to receive the gas discharged from the reaction chamber by the pump of the pumping unit, the decomposition apparatus including an external electrode unit coupled to a reference voltage, an internal electrode unit supported by the external electrode unit, and a voltage generator connected to the internal electrode unit, the external electrode unit comprising a tubular housing having opposite open ends, the interior of the housing communicating with the pumping unit through one of the open ends of the housing such that the gas containing PFCs discharged from the reaction chamber by the pumping unit flows into the tubular housing through the one of the open ends; the internal electrode unit comprising an electrically conductive shaft, electrically conductive supports connected to the shaft and suspending the shaft within the tubular housing such that the shaft is substantially coaxial with the tubular housing, and a plurality of implanter poles fixed to the shaft so as to be electrically conductively connected to the shaft, the implanter poles protruding radially toward the housing of the external electrode unit and spaced radially inwardly of an inner surface of the housing of the external electrode unit such that a reaction space is defined by and between the implanter poles and the housing of the external electrode unit, and the implanter poles being spaced at regular intervals in a circumferential direction of the housing, and the voltage generator electrically conductively connected to the supports such that electrical energy is applied to the PFCs discharged by the pumping unit to decompose the PFCs into compounds that can be wet processed; and a scrubber connected to the decomposition apparatus via the other end of the tubular housing of the external electrode unit so as to receive and wet process the compounds which have been decomposed by the decomposition apparatus.
