TECHNICAL FIELD

[0001] The utility model belongs to the petroleum drilling oil base rock debris processing technical field, concretely relates to an oil base rock debris thermal desorption device. BACKGROUND

[0002] With the increasing demand for oil and gas resources worldwide, drilling activities are becoming more frequent, and the resulting oil-based rock debris is also gradually increasing. These rock debris not only contains mineral components in the original geological layer, but also carries a large amount of drilling fluid residues, mainly including base oil, emulsifiers and other chemical additives. Since oil-based rock debris has a high pollution risk, how to efficiently and environmentally treat these waste has become an important issue in the field of environmental protection.

[0003] Thermal desorption technology, as an effective pollution control method, has been widely used in oil-based rock debris treatment. This technology converts organic pollutants adsorbed or mixed in solid media into gas through heating, thereby achieving separation and recovery of pollutants. However, the existing oil-based rock debris thermal desorption device still faces many challenges in actual application, one of which is the feeding blockage problem. Because oil-based rock debris usually contains a certain proportion of viscous oil and moisture, these components may cause material clumping or sticking under certain conditions, thereby causing blockage at the funnel inlet.
