Abstract: A pyrolysis apparatus for completely separating an EVA crystal silicon wafer from a waste photovoltaic module includes a heating mechanism controlled by a control system and mounted in a pyrolysis box and being capable of performing telescopic motion in a vertical direction; an overturning assembly for fixedly clamping and driving a photovoltaic module to overturn, the overturning assembly is arranged just under the heating mechanism; and a splitting assembly for separating the photovoltaic module, the splitting assembly is arranged at a left side of the photovoltaic module fixedly clamped by the overturning assembly. A splitting apparatus is provided for assisting in splitting EVA, and isolating glass from the crystal silicon wafer, as well as isolating a back plate from the crystal silicon wafer, and therefore, the pressure generated on the crystal silicon wafer due to large strength of the glass and shrinkage of the back plate is prevented.
