NOVELTY - Swill-cooked dirty oil methyl esterification device comprises waste oil storage tank, pre-reaction kettle, a bag-type filter, pre-esterification electric heating reaction kettle, transesterification electric heating reaction kettle, centrifuge, fatty acid methyl ester distillation tower, glycerol distillation tower and a methanol refining tower. The waste oil storage tank, pre-reaction kettle and the bag-type filter through the pipeline and pump are in turn connected. The outlet end of the bag type filter is connected to the electric heating reaction kettle feeding port through the pipeline.    USE - Used as a swill-cooked dirty oil methyl esterification device.    ADVANTAGE - The device is safe, environmental friendly, and has high efficiency; and produces high quality biodiesel with improved production efficiency and reduced production cost.    DETAILED DESCRIPTION - Swill-cooked dirty oil methyl esterification device comprises waste oil storage tank, pre-reaction kettle, a bag-type filter, pre-esterification electric heating reaction kettle, transesterification electric heating reaction kettle, centrifuge, fatty acid methyl ester distillation tower, glycerol distillation tower and a methanol refining tower. The waste oil storage tank, pre-reaction kettle and the bag-type filter through the pipeline and pump are in turn connected. The outlet end of the bag type filter is connected to the electric heating reaction kettle feeding port through the pipeline. The pre-esterified electric heating reaction kettle material outlet through the pipeline and pump is connected to the transesterification electric heating reaction kettle feeding port. The transesterification electrically heating reactor through the pipeline and pump is connected to the inlet end of the centrifuge. The lighter liquid outlet end of the centrifuge is connected to the lower part of fatty acid methyl ester distillation tower inlet end, and the heavier liquid outlet end of the centrifuge is connected to the lower part of the glycerol distillation tower inlet end. The upper part of the glycerol distillation tower outlet end through the pipeline is connected to the lower part of the methanol tower inlet end, and the methanol refining tower upper outlet end is connected to the transesterification electric heating reactor feed inlet through the pipeline.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the swill-cooked dirty oil methyl esterification device.
