Pyrolysis recycling treatment system for oil sludge

Abstract

The invention discloses a pyrolysis recycling treatment system for oil sludge. The system comprises a superthermal furnace, a treatment box, an oil-water separation box and a cooling tower, wherein the superthermal furnace is communicated with the treatment box, and the oil-water separation box is communicated with the cooling tower; a feeding mechanism is connected with one side of the treatmentbox, and a first-stage gas-solid separation cylinder and a second-stage gas-solid separation cylinder are arranged between the treatment box and the oil-water separation box in sequence; a residue conveying mechanism is arranged below the first-stage gas-solid separation cylinder; a residue collecting box is arranged below the second-stage gas-solid separation cylinder. The system has beneficial effects as follows: instant evaporation of oil and water is realized under the dual actions of high temperature and impact wave of steam, gas-solid separation is realized by swirling dedusting, oil-water separation is realized by specific gravity, no chemical elements are needed in the treatment process, secondary pollution can be avoided, and with adoption of instant evaporation, compositional change can be avoided, and the oil recycling 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 ...
