Abstract

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; ribs are arranged on the casing with the heating cavity. Fume inside the flue flashes the casing with the heating cavity, so that the heat can be conducted; due to adoption of the ribs on the casing with the heating cavity, the heat exchange area is effectively increased when being compared with that of the prior art, and the heat exchange efficiency of the thermal decomposition device is improved.

Description

technical field [0001] The invention relates to the technical field of recovery and treatment of oilfield waste, 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 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 ...
