高含水油泥热干化处理设备研究与应用进展OA北大核心CSTPCD

High-water-content oil sludge is a stable multiphase emulsification system,and its dehydration and drying treatment is the bottleneck of its subsequent treatment and disposal.The paper provided an overview of the sources,composition,and characteristics of high-water-content oil sludge,summarized the research and application of oil sludge thermal drying treatment equipment,compared the advantages and disadvantages of different thermal drying equipment,and analyzed the main problems and corresponding reasons in the oil sludge thermal drying process and proposes corresponding solutions to the problems.It pointed out that demulsification,oil removal and tempering pretreatment are the main means to reduce the oil content of oil sludge and reduce the molecular weight of large organic compounds.On this basis,the advantages,disadvantages,and adaptability of various methods for demulsification,oil removal,and tempering pretreatment were compared,and the future research directions and development trends of thermal drying technology and equipment were discussed.
