Oil sludge pyrolysis treatment system and treatment method thereof

Abstract

The invention discloses an oil sludge pyrolysis treatment system which comprises a super-thermal furnace, a treatment box, an oil-water separation tank and a cooling tower, wherein the super-thermal furnace is communicated with the treatment box; the oil-water separation tank is communicated with the cooling tower; one side of the treatment box is connected with a feed mechanism; a primary gas-solid separation cylinder and a secondary gas-solid separation cylinder are sequentially arranged between the treatment box and the oil-water separation tank; a residue conveying mechanism is arranged below the primary gas-solid separation cylinder; and a residue collection tank is arranged below the secondary gas-solid separation cylinder. The oil sludge pyrolysis treatment system has the beneficialeffects that the device is capable of realizing instantaneous steaming of oil and water by utilizing high-temperature and shock wave dual effects of vapor, gas-solid separation is realized by utilizing vortex dust removal, oil and water separation is realized by utilizing specific gravity, no chemical element needs to be added in the treatment process, and secondary pollution is avoided. Meanwhile, compositional variation is not caused by adopting instantaneous steaming, and the oil recovery utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of sludge treatment devices, in particular to an oil sludge pyrolysis recovery treatment system. Background technique [0002] Oilfield sludge mainly refers to the soil mixture formed by mixing crude oil, soil, sand and water due to various reasons. With the continuous increase of oil production and consumption, the pollution caused by petroleum substances entering the soil is becoming more and more serious. Therefore, solving the problem of oil pollution in oilfield soil has become an important content in the prevention and control of soil pollutants. [0003] The applicant found that there are at least the following technical problems in the prior art: the current oil sludge treatment equipment mostly adopts two methods of adding chemical reagents and heating distillation, adding chemical reagents is likely to cause secondary pollution, and heating and distillation is easy to change the composition of oil ...
