The invention provides a combined ex-situ thermal desorption treatment system for oil sludge. The system comprises a low-temperature preheating module configured to preheat the oil sludge, desorb and volatilize petroleum hydrocarbon in the oil sludge step by step, reduce the viscosity of the oil sludge and form a preheated oil sludge material for conveying the preheated oil sludge to a high-temperature thermal desorption module; a petroleum recovery module configured to be connected with the low-temperature preheating module and used for condensing and recovering the petroleum hydrocarbon-containing gas exhausted by the low-temperature preheating module so as to realize the function of recovering petroleum in the oil sludge; and the high-temperature thermal desorption module configured to perform thermal desorption and thermal remediation on the preheated oil sludge and recycle waste heat of the heating kiln body, so that the heat utilization rate is increased, wherein the preheating temperature is lower than the temperature of the thermal desorption additional heat.
Description
technical field [0001] The invention relates to the technical field of soil remediation, in particular to a combined ex-situ thermal desorption treatment system for oil sludge. Background technique [0002] At present, the problem of soil pollution in my country is becoming more and more prominent, among which organic pollutants, especially petroleum pollutants, have become one of the important factors leading to the problem of safe use of soil. The composition of petroleum pollutants is complex, containing teratogenic, carcinogenic, and mutagenic substances (such as halogenated hydrocarbons, benzene series, anilines, phenanthrene, benzo[a]pyrene, etc.), once entering the soil, it will be harmful to human health and ecology. serious harm to the environment. Therefore, the treatment of oil sludge has attracted great attention from the public and scientific and technological workers. At present, the remediation technologies of oil sludge mainly include extraction and elution...
