The invention relates to a rotary waste cracking device. The rotary waste cracking device comprises a pyrolyzing furnace and a driving mechanism driving the pyrolyzing furnace to rotate. The pyrolyzing furnace comprises a thermal insulation drum, an outer drum and an inner drum which share the axis of rotation, wherein the inner wall of the outer drum is provided with a plurality of decoking mechanisms; each of the decoking mechanisms comprises a fixed part and a rod part connected with the fixed part; and the extending end of each rod part butts against the outer wall surface of the inner drum. During rotation of the inner drum, a point where the outer wall surface of the inner drum contacts with one decoking mechanism is defined as a contact point, and relative to the fixed part of the decoking mechanism, the contact point moves towards a direction away from the fixed part. The rotary waste cracking device with the coke cleaning mechanism in the invention is simple in structure and low in cost; the coke cleaning function of the outer wall surface of the inner drum is realized through the plurality of decoking mechanisms, so heat transfer efficiency and heat transfer uniformity are improved; and thus, the quality of a pyrolysis reaction is ensured.
Description
technical field [0001] The invention relates to the field of pyrolysis mechanical equipment, in particular to a rotary waste cracking device. Background technique [0002] The rotary waste cracking device is used to realize high-temperature pyrolysis of waste organic materials, and produce organic products such as fuel oil, gas and carbon black in the process, so as to realize waste reuse. [0003] In the prior art, due to the high temperature environment of the thermal cracking reaction in the rotary waste cracking device, it is inevitable to cause coking phenomenon. The so-called coking phenomenon is the solidification and adhesion of organic substances in the waste cracking device on the inner wall of the reaction chamber of the waste cracking device. This phenomenon It will lead to uneven heat transfer in the reaction chamber, thereby affecting the progress of the pyrolysis reaction. The coking removal mechanism adopted in the prior art usually has a complex structure, h...
