Abstract

PURPOSE: To recover oil contents effectively as fuel oil by extracting the oil contents in oily sludge by the extracting agent composed of the oil of the same nature, coarsening the particles of the water contents in the extracted oil after having been removed of solids and separating these from the oil contents.
CONSTITUTION: Oil A1 of the same nature as that of the oil A1 in oily sludge A is supplied into an oil extracting unit 1, where it is heated and stirred 1i, to which the sludge A is charged 1b with heating and stirring. This results in the extraction of the oil A1 in the sludge A into the same nature oil A1 and sedimentation of coarse solids A2-1, which are then scraped up by transport vanes 1i and are discharge 1d to the outside of the unit 1. On the other hand, the extracted oil A1is overflown via overflow weir 1k and underflow weir 1l and is further sent to an oil tank 2. Next, part of the oil A1 in the tank 2 is sent to the unit 1 and the rest to a solid- liquid centrifuge 6, respectively. In the centrifuge 6, the oil A1 and fine solids A2-2 are separated and the oil A1 is passed through a water drop coasening unit 8, whereby the micro water droplets contained are gathered to coarser particles, which are further sent to a liquid-liquid centrifuge 9 to be separated to the oil A1 and water content A3. The oil A1 is recovered.
