FIELD: alternate fuels. ^ SUBSTANCE: invention relates to a plant for reusing oil-containing wastes obtained from washing of oil storage tanks to produce secondary fuel. Plant has caisson for stratification of pollutants, waste-supply pumps, conduits with shutoff gate valves to discharge finished product, cleaning solution, and sludge. Plant is further provided with second caisson for purifying spent oil and heated third caisson to prepare stratifying solution, which caisson has bubbling pump, and, connected to both caissons, ejector mixer for mixing stratification agent with water and valve gate positioned between caissons. Bubbling pump is connected to first and second caissons through conduits with shutoff gate valves and first and second caissons are connected through shutoff gate valves to third caisson and to mixer for mixing purified mazut with purified motor oil, which mixer is provided with outlet tube for finished product. ^ EFFECT: achieved high quality of cleaning tanks by repetitive use of cleaning solution and leading to production of secondary fuel. ^ 1 dwg |
