Description

Technical Field

[0001] The utility model relates to the technical field of waste oil sludge pyrolysis, in particular to a harmless waste oil sludge pyrolysis treatment device. Background Art

[0002] During the oil field exploitation process, a large amount of oily sludge is generated, which requires environmental protection care. Usually, the sludge needs to be pyrolyzed at high temperature to remove the oil in the sludge. The existing pyrolysis device can only penetrate and heat the sludge from the side to the middle of the sludge, and cannot quickly heat the sludge in the middle of the sludge heating barrel, resulting in slow overall heating speed of the sludge, and then resulting in slow sludge pyrolysis efficiency.

[0003] A Chinese patent discloses a periodic pyrolysis treatment device for waste oil sludge (authorization announcement number CN220351951U). The patent technology can drive the hollow shaft, heating tube and crushing heat-conducting parts to rotate simultaneously by starting the motor, and the hot gas can heat the middle and outer parts of the waste oil sludge through the hollow shaft, heating tube and heated crushing heat-conducting parts at the same time, thereby improving the heating efficiency of the waste oil sludge and thus improving the pyrolysis efficiency of the waste oil sludge.

[0004] However, it has certain disadvantages: after the pyrolysis is completed and the material is discharged, the residual oily sludge will inevitably adhere to the inner wall of the oily sludge heating barrel. Over time, these residues will gradually accumulate and dry, forming a hard and difficult to remove scale layer, which greatly increases the difficulty of subsequent cleaning. Utility Model Content
