Embodiment Construction

[0028] The invention relates to a method for treating oily sludge. First, the oily sludge is diluted from a viscous state to a fluid state by the first quenching and tempering treatment, followed by heating and ultrasonic treatment to initially separate water, oil, and mud into three phases , To obtain separated oil and solids, and then use the second quenching and tempering treatment for deep oil-solid separation, and finally, the oil is separated by a horizontal screw centrifugal machine, the sludge solids are dried, standing for precipitation, oil-water layer separation, crude oil Recycle and complete the treatment of oily sludge. In the whole process, two quenching and tempering treatments are carried out according to the characteristics of the sludge, the efficiency of oil washing is higher, and the utilization rate of the medicament is higher. Ultrasonic and mechanical centrifugal methods are also used to speed up the process, further improve the efficiency of oil washing...

Abstract

The invention provides a method for treatment of oily sludge. The method includes the steps of primary conditioning and tempering treatment, namely adding sludge, water, a demulsifier and a flocculantin a certain proportion, and diluting the sludge to the flow state from a viscous state via full mixing with mechanical stirring; ultrasonic treatment, namely heating a sludge and water mixture subjected to primary conditioning and tempering into 45-55DEG C for ultrasonic treatment; secondary conditioning and tempering treatment, namely adding an alkaline dispersing agent and a dehydrating agentto carry out secondary conditioning and tempering treatment on depth-level oil which is not completed separated in the previous treatment for further oil-solid separation; centrifugal separation; drying and oil-water layer separation.

Description

Technical field [0001] The invention relates to an oily sludge treatment method, which combines the advantages of extraction method and ultrasonic method, gives full play to the residual value of oily sludge, achieves the dual goals of environmental protection and energy recovery, and realizes the reduction of oily sludge Less, harmless and resourceful. The invention has the advantages of scientific and reasonable design, simple operation, easy realization, low energy consumption, low investment, high oil washing efficiency and large economic benefits, and is a highly innovative oily sludge treatment method. Background technique [0002] As the world’s demand for oil and minerals continues to increase, soaring prices of oil and minerals have stimulated the development of new resources and new technologies in oil resource countries, and the mixing of crude oil or refined oil in the process of oil extraction, transportation, refining and oily sewage treatment A mixture of various ...
