[0002] Oil-based mud is a solid pollutant produced during oil well exploitation. It is a complex multiphase system containing mineral oil, phenolic compounds and heavy metals. Its leachate is highly toxic. Continuous thermal desorption is a method for treating oil-based mud. Its principle is to desorb the combustible and other organic substances that are vaporized from the water components and oil components in oil-containing sludge or oil-based mud under high temperature conditions, and discharge the dry residue of the solid components after dehydration and deoiling, thereby realizing the regeneration and recycling of the mud, meeting environmental impact assessment and related environmental protection requirements, and achieving the effect of harmlessness.

[0003] During the recycling process of waste oil-based mud, since the oil-based mud contains solid particles, the solid particles will condense on the inner wall of the feed pipe during the feeding process of the oil-based mud, causing the diameter of the feed pipe to decrease and thus lead to blockage of the feed pipe.
