Abstract

The invention belongs to the technical field of hazardous waste treatment, and particularly relates to a device for recovering oil in drilling oil-based mud rock debris. The device comprises a heating kettle, a swirler, a condensing device, an oil liquid storage tank and a solid phase storage tank, wherein a feed port, a discharge port, an oil-containing steam outlet and a gas medium inlet are formed in the heating kettle; the discharge port of the heating kettle communicates with a feed port of the swirler; and the condensing device comprises a cooler, a cooling water unit and a high-speed centrifugal machine. According to the scheme, the swirler and the centrifugal machine are arranged, so that oil-containing solid particles are deoiled twice, additionally, non-condensable gas and gas media which flow out of the condensing device are heated and then are introduced into the high-speed centrifugal machine, so that oil on the oil-containing solid particles is flushed cleanly, the deoiling effect is good, the oil content of solid particles in the finally produced oil-based mud rock debris is low, and additionally, the solid particles with low oil content are fed into a cement kiln to be incinerated and decomposed at high temperature, so that the environment is not polluted.

Description

technical field [0001] The proposal belongs to the technical field of hazardous waste treatment, and specifically relates to a device for recovering oil from drilling oil-based mud cuttings. Background technique [0002] Drilling oil-based cuttings are a kind of solid waste produced during the drilling of oil and gas resources. Since they contain a large amount of oil, direct discharge will seriously pollute the environment. They are hazardous wastes clearly stipulated by the state. The harmless treatment of drilling oil-based mud cuttings has become a pain point and difficulty in the process of green exploitation of oil and gas resources. At present, my country's oil-based mud uses diesel oil, white oil, bio-oil, mineral oil, synthetic oil, etc. The content of aromatic hydrocarbons is high and has significant biological toxicity. If it is not treated effectively, it will have a serious impact on the regional environment. At the same time, if the oil base in the oily waste ...
