Abstract

The embodiment of the invention discloses a thermal decomposition device of oil field wastes. The thermal decomposition device comprises a casing, wherein a flue and a heating cavity are formed inside the casing; the heating cavity is isolated from the flue. The oil field waste thermal decomposition device is characterized in that a plurality of partitioning plates are arranged on the inner wall of the casing; the flue is of a snakelike structure through the adoption of the partitioning plates. Through the adoption of the partitioning plates on the inner wall of the casing of the thermal decomposition device disclosed by the invention, the flue inside the casing is of the snakelike structure, so that the flowing direction and the flowing speed of fume are changed, the turbulent flow effect is improved, the retention time is prolonged, and the heat exchange efficiency of the heating cavity and the fume is improved.

Description

technical field [0001] The invention relates to the technical field of oilfield waste treatment, in particular to a thermal decomposition device for oilfield waste. Background technique [0002] As the country intensifies the development of unconventional energy sources such as shale gas, waste oil-based mud and oily cuttings are continuously produced and accumulated in large quantities. The oily cuttings produced by a single well during the drilling stage are about 300-500 tons, of which oily substances Accounted for 25-30%. [0003] In oil and gas exploration, development and production, improper disposal of waste oil-based mud and oily drilling cuttings will cause serious pollution of water resources, soil, etc., and restrict development progress. Therefore, the harmless treatment of oil-based mud and oily drilling cuttings has generally received attention. Countries around the world have done a lot of work on the toxicity analysis, environmental impact assessment and tr...
