APPARATUS FOR REFINING WASTE OIL HAVING DUALISTIC PACKING

摘要

PURPOSE: An apparatus for refining waste oil having a dualistic packing is provided to wash packings easily for a short time, and to reduce workforce which is used for packing washing to remove sludge. CONSTITUTION: An apparatus(1000) for refining waste oil having a dualistic packing includes the following: a furnace(1200) collecting pre-processing refining oil(1220) of a gas state by heating the waste oil(1110) which is transferred through a waste oil inlet(1210); a vacuum distillation column(1300) having a first packing part(1310), a second packing part(1320), and a liquefaction unit(1330); a circulation pump(1400) connected to the vacuum distillation column to flow the refining oil(1350); a cooling heat exchanger(1500) cooling the refining oil; a refined oil tank(1600) receiving a part of the refining oil; and a manhole part(1340) capable of taking out the first packing part.
