Problems solved by technology

For example, Chinese patent document CN104310734A discloses a kind of oily sludge treatment agent, which can effectively reduce the oil-water interfacial tension at room temperature, and the treatment effect of oily sludge is relatively good, and the oil phase recovery rate can reach more than 96%, but Biological enzymes such as protease and lipase are added to the formulation of the oily sludge treatment agent, which makes it more sensitive to temperature changes, which is not conducive to the performance of the agent
Chinese patent document CN106277709A discloses an environmentally friendly cleaning agent for treating oily sludge. When the amount of the cleaning agent is 2 wt% of the oil sludge, the final oil recovery rate reaches 95.9%, and the treatment effect is relatively good. The disadvantage is that there are many substances added to the cleaning agent, and there are as many as three types of surfactants, and the ratio between water and sludge is relatively large, which increases the difficulty of the treatment process to a certain ex

Abstract

The invention relates to an emulsion-type water-based cleaning agent for oily sludge and a preparation method and an application method thereof. The emulsion-type water-based cleaning agent comprises the following components by mass: 2-10 parts of a surfactant, 3-10 parts of an oil soluble component and balance of a water phase. The preparation method is that the surfactant, the oil soluble component and the water phase are stirred and mixed evenly at room temperature to obtain the uniform and stable emulsion-type water-based cleaning agent. When in use, the oily sludge is first mixed with the emulsion-type water-based cleaning agent, and stirred at certain temperature, after the cleaning is completed, oil, water and solid three phase separation is performed on the mixture, and finally the solid phase is washed with hot water of the same temperature for one time. The emulsion-type water-based cleaning agent for the oily sludge has high safety and high efficiency, the preparation method is simple, and the treatment effect of the oily sludge is satisfactory.

Description

technical field [0001] The invention relates to an emulsion-type water-based cleaning agent for cleaning oily sludge, and at the same time relates to a preparation method and a use method of the water-based cleaning agent, belonging to the technical field of cleaning oily sludge. Background technique [0002] Oily sludge is a solid waste produced during the process of oil exploitation, storage and transportation, refining and oily sewage treatment. It contains not only petroleum hydrocarbons, but also toxic and harmful substances such as benzene series, phenols and heavy metal salts. Not only Occupies land and space, and if it is discharged directly without treatment, it will seriously pollute air, soil and groundwater. It has been included in the "National Hazardous Waste List", which restricts the development of domestic oil field production to a certain extent. At the same time, oily sludge is a resource. If a treatment technology can be developed that can eliminate the e...
