The refining apparatus includes a feeding device, a pyrolysis furnace, a chloride-decomposing device, a first condensation device, a temporary storage, a still, a sieve plate tower, a second condensation device, and a receiving tank. The waste plastics are cracked by the pyrolysis furnace to produce plastic gas by heating. The chlorides of the plastic gas are removed by the chloride-decomposing device having the ammonia to produce a first oil gas. The first oil gas is condensed by the first condensation device to produce raw oil. The raw oil is heated by the still to produce a second oil gas. The second oil gas is sieved by the sieve plate tower to produce a third oil gas. The third oil gas is condensed by the second condensation device to produce finished oil received by the receiving tank.
