The invention discloses a pyrolysis system for oil slit of a plasma hot-blast stove. The pyrolysis system comprises a plasma heat release system, an oil slit heat absorption system and a waste heat recycling system, wherein the oil slit heat absorption system comprises an oil slit pipeline inlet (1), an oil slit pipeline heating section (15), a screw propeller (2), a pyrolysis product extracting pipeline (3) and a waste material outlet (4); the plasma heat release system comprises a plasma generator (5), an air distributing chamber (6), air caps (7) and a hot-blast stove (8); the waste heat recycling system comprises a hot air extracting pipeline (9), an induced draft fan (10), a heat exchanger (11), a hot air circulating pipeline (12), the pyrolysis product extracting pipeline (3), the heat exchanger (11), a separator (13) and a non-condensable gas ignitron (14). The pyrolysis system can be used for continuously processing a large number of oil slit and has the advantages of zero discharge, high waste heat recovery efficiency and relatively high economic and environment-friendly benefits.
