Problems solved by technology

If the oil sludge is left unattended, it will cause serious pollution to the soil and groundwater, and the smell will also pollute the air
At present, domestic treatment methods for oil sludge mainly include stacking method, landfill method, incineration method, biological treatment and other means, but due to the respective limitations of the above methods, no better technology has become the mainstream

Abstract

The invention relates to an oil sludge drying treatment system which comprises a drying device, a cyclone separation device, a micro-powder gas-solid separation device, a gas-water separation condensing device, a tail gas adsorption device and a vacuum pump system. The invention also provides an oil sludge drying treatment process using the oil sludge drying treatment system. According to the oilsludge drying treatment system, the drying device is used for heating the oil sludge and separating moisture in the oil sludge, the cyclone separation device is used for separating solids in steam generated by heating the oil sludge, the micro-powder gas-solid separation device is used for carrying out secondary separation on the solids in the steam, the gas-water separation and condensation device is used for spraying tail gas to carry out adsorption and cooling, and the tail gas adsorption device is used for carrying out secondary adsorption. The system and the process are efficient, safe and capable of treating a large amount of oil sludge in a centralized manner so that the economy, safety and efficiency of oil sludge treatment are improved.

Description

technical field [0001] The invention relates to the technical field of oil sludge drying, in particular to an oil sludge drying treatment system and process. Background technique [0002] Oily sludge is oily sludge produced in the process of petroleum exploitation. It is bulky and contains not only complex organic components in petroleum, but also water and sludge. Therefore, it has high oil content, high viscosity, complex components, and many harmful components. features. If the oil sludge is left unattended, it will seriously pollute the soil and groundwater, and the odor produced will also pollute the air. At present, domestic treatment methods for oil sludge mainly include stacking, landfill, incineration, biological treatment and other means. However, due to the limitations of the above methods, no better process has yet become the mainstream. However, from the perspective of economic and environmental protection, the reduction, harmlessness, resource utilization and...
