Abstract

The invention discloses a separation device for separating oil from oil-containing mud. The separation device comprises a separation tower, an air floating device with a bubble generating device, stirring impellers and a separation unit, wherein the air floating device is fixedly mounted in the separation tower and is capable of producing charged microbubbles, the stirring impellers are mounted in the separation tower, the separation unit is mounted at the upper part of the separation tower and comprises an oil guiding slot, the stirring impellers are used for stirring mud, the oil content in the mud is adsorbed with the microbubbles to float to the mud surface, and the oil content on the mud surface overflows out of an upper opening of the separation tower under the pushing of air and flows into the oil guiding slot. The separation device has the advantages that the oil-mud separation is realized, i.e., the oil is recycled, oil in discharged mud is removed, the secondary pollution is avoided, and the energy is saved during the operation.

Description

technical field [0001] The invention relates to a separation device for separating oil from oily mud. Background technique [0002] Some oily sludge will be produced in the process of drilling, fracturing, production, oil-water separation and transportation in the oil field. The oily sludge seriously pollutes the land and must be deoiled before it can be used as a resource. The existing treatment methods include chemical heat washing method, fuelization method, pyrolysis method, steam injection method, solvent extraction method, and microbial restoration method. Except that the microbial remediation method is suitable for degrading oily sludge with low oil content and has no secondary pollution, all other methods will produce organic waste gas or secondary pollution such as residual chemical components to varying degrees, and the energy consumption is high. The investment is large and the control is complicated, which is not conducive to large-scale promotion and applicatio...
