Embodiment Construction

[0023] like figure 1 As shown in the figure, a harmless treatment system for tank cleaning sludge includes a tank cleaning sludge storage tank and a heating and homogenizing system (simple filtration of tank cleaning sludge through a grille, heating the sludge to 60°C by turning on the heat conduction oil boiler, stirring evenly It is convenient for the follow-up process after being refined, and the slurry pump is used to introduce the chemical dosing homogeneous system), the heat transfer oil heating system (the heated heat transfer oil is transported to the part that needs to be heated through the pipeline), the chemical dosing homogeneous system (adding heat to the processing system) medicine, adjust the solid-liquid ratio in the homogeneous system to meet the requirements of the subsequent centrifuge), three-phase separation system (the oil, water, and mud in the homogeneous system are separated twice, and the separated oil enters the crude oil tank, the sewage enters the ...

Abstract

A harmless treatment system for tank cleaning oil sludge comprises a tank cleaning oil sludge storage pool, a heating homogenizing system, a heat conduction oil heating system, a dosing homogenizing system, a three-phase separation system, a pyrolysis carbonization system, a sewage temporary storage system, a waste oil tank and a sewage tank. An outlet of the tank cleaning oil sludge storage pool is sequentially connected with the heating homogenizing system, the dosing homogenizing system, the three-phase separation system and the pyrolysis carbonization system through pipelines. An outlet of the dosing homogenization system is connected with the three-phase separation system and is also connected with the waste oil tank and the sewage tank. Similarly, the outlet of the three-phase separation system is connected with the pyrolysis carbonization system and is also connected with the waste oil tank and the sewage tank. According to the invention, manpower and material resources are saved in the tank cleaning oil sludge treatment process. Not only can crude oil in the tank cleaning oil sludge be recycled, but also it can be ensured that the treated solid residues cannot cause harm to the environment. The problems that existing tank cleaning oil sludge is difficult to treat and does not reach the standard after treatment are solved.

Description

technical field [0001] The invention relates to a system and a treatment process for harmless treatment of tank cleaning oil sludge, which is mainly used in the harmless treatment of tank cleaning oil sludge in oil fields. Background technique [0002] Tank clearing sludge is mainly divided into two categories: one is produced in the process of oil production sewage treatment, due to the specific gravity factors such as silt and heavy oil in the sewage itself, a small amount of crude oil sinks to the removal The bottom of the oil tank, and then form black, fine-grained, oily sludge; the second type is produced during crude oil storage. When oil storage tanks store oil, especially crude oil, during long-term storage, the oil A small amount of mechanical impurities, gravel, soil, heavy metal salts, and heavy oil components such as paraffin and asphaltene will naturally settle and accumulate at the bottom of the tank due to the difference in specific gravity, forming a black an...
