FIELD: process engineering.
SUBSTANCE: invention may be used in oil and oil processing industries for cleaning oil-contaminated soils and accumulating oil sludge spilled on water surface. Proposed device using recirculated water allows cleaning practically all soils, bottom depositions and whatever sludges, and increasing cleaning quality. Circulation and recover of recirculated water by preparing oil-contaminated soil pulp with heated recirculated water and by continuous extraction of larger inclusions, including soil fine and light particles and oil product, allows increasing cleaning quality.
EFFECT: increased efficiency of cleaning.
