  • Patent number: 8574504
    Abstract: A plasma scrubber that forms a high temperature atmosphere in a reactor to effectively decompose and remove a non-biodegradable gas and reduce power consumption is disclosed. The plasma scrubber includes: a first reactor to which a non-biodegradable gas is supplied; an electrode installed in the first reactor and protruding in the flow direction of the non-biodegradable gas to generate plasma in the non-biodegradable gas supplied between the electrode and the first reactor by a discharge reaction in the first reactor; a second reactor connected to the first reactor to form continuous arc jets by anchoring the plasma to the electrode; and a third reactor connected to the second reactor to decompose the non-biodegradable gas by forming a reaction section of high temperature that contains electrons and chemical species of high reactivity in the second reactor and thereby increasing the stay time and reactivity of the non-biodegradable gas.

  • Patent number: 8272206
    Abstract: A reduction system for particulate materials in exhaust gas, which is connected to a tailpipe of an engine that burns a hydrocarbon-based fuel supplied from a fuel storage tank, and collects and removes particulate materials within the exhaust gas, may include a plasma reactor having a gas inlet and an outlet, and a DPF (diesel particulate filter) trap having a filter. The tailpipe of the engine may communicate with the gas inlet of the plasma reactor, and the outlet of the plasma reactor may communicate with the DPF trap. The exhaust gas exhausted from the engine may be transferred to the DPF trap after being heated while passing through the plasma reactor.

  • Patent number: 8257455
    Abstract: A plasma burner and a diesel particulate filter (DPF) trap that can effectively oxidize and remove a particulate material (PM) within an exhaust gas by preheating fuel and mixing the fuel with the exhaust gas are provided. The DPF includes: a filter that is connected to an exhaust conduit at a side opposite to that of an engine; a plasma burner that is provided within the exhaust conduit between the engine and the filter, and that includes a fuel inlet that supplies fuel and a flame vent that projects a flame by a plasma discharge, and that heats exhaust gas; and a fuel inflow conduit that connects the fuel inlet and a fuel tank.
