Embodiment 1
[0029] like figure 1 As shown in the figure, the treatment method of oily sludge on the offshore platform includes pretreatment, thermal desorption and desorption treatment, exhaust gas treatment, and wastewater treatment;
[0030] The pretreatment step includes the sorting and crushing of foreign matter, and the sorted oily sludge is transported to the pyrolysis desorption reactor, and the foreign matter is crushed and then transported to the pyrolysis desorption reactor.
[0031] The thermal desorption and desorption treatment is completed in the thermal decomposition and desorption reaction kettle, and the inner wall of the thermal decomposition and desorption reaction kettle and the interior of the thermal decomposition and desorption reaction kettle are heated at the same time. The interior of the pyrolysis and desorption reactor is heated by superheated steam. The superheated steam is introduced from the lower part of the pyrolysis and desorption reactor, and then spraye...

The invention belongs to the technical field of processing of oily sludge and particularly relates to a processing method of oily sludge on an offshore platform. The processing method of the oily sludge on the offshore platform comprises pyrolysis desorption processing, tail gas processing and waste water processing; the pyrolysis desorption processing is completed in a pyrolysis desorption reaction kettle, the inner wall of the pyrolysis desorption reaction kettle and the inside of the pyrolysis desorption reaction kettle are simultaneously heated, the pyrolysis desorption reaction kettle is vertically arranged, and the oily sludge is discharged from the pyrolysis desorption reaction kettle after being subjected to transverse centrifugation and vertical rollover in the pyrolysis desorption reaction kettle; the tail gas processing is used for processing tail gas obtained after a pyrolysis product generated in the pyrolysis desorption reaction kettle is subjected to three-phase separation; the waste water processing is used for processing waste water obtained after the pyrolysis product generated in the pyrolysis desorption reaction kettle is subjected to three-phase separation. According to the processing method of the oily sludge on the offshore platform, when an occupied area of equipment is reduced, processing efficiency of the oily sludge can be improved.
Description
technical field [0001] The invention belongs to the technical field of oily sludge treatment, and in particular relates to a treatment method for oily sludge on an offshore platform. Background technique [0002] With the development of offshore oil, more and more attention has been paid to the pollution of the marine environment caused by the sludge produced in the development of offshore platforms. In 2008, my country formulated GB49142008 "Concentration Limits of Pollutant Discharge Concentration for Offshore Petroleum Exploration and Development", which regulates the treatment and equipment of pollutants produced by offshore oil exploration and development. Commonly used treatment methods are mainly divided into three categories according to different principles: physicochemical method, biochemical method and electrolysis method. At present, the mature technology in China is to use the LRET technology, that is, the mechanical separation of oil-based drilling cuttings - ...
