Description
Technical field
The invention belongs to chemical agent field, and in particular to the formula and preparation method of a kind of oily sludge demulsifier.
Background technology
At present, no matter the conventional method of international or domestic oily sludge include burning method, bioanalysis, hot water washing,
The methods such as pyrogenic process, Thermal desorption is a kind of more advanced method during the oil-sludge treatment of reality, and it can be reclaimed containing sludge
Heat and other using component, but the maximum shortcoming of Thermal desorption technology is dangerous waste to be produced in construction, so can more be improved
The financial cost of improvement.The processing of current China oily sludge also larger gap compared with using with Foreign Advanced Lerel：Place
Reason device technique falls behind, technology is not matched, it is not enough to handle infusion of financial resources, can cause the huge waste of environmental pollution and resource.
The characteristics of this patent is maximum be by Chemical cleaning can recovery section oil, so as to bring economic benefit.
The content of the invention
It is an object of the invention to the defect for overcoming prior art, there is provided a kind of formula of oily sludge demulsifier and preparation
Method, the formulation ratio science, technique is simple, low manufacture cost, and can be used for oil-sludge treatment, it is possible to reduce greasy filth is dirty
Dye, can greatly improve the effective rate of utilization of petroleum hydrocarbon, can provide technological reserve for soil remediation from now on.
To achieve these goals, technical scheme is as follows：
The formula and preparation method of a kind of oily sludge demulsifier, the oily sludge demulsifier include following components:Citric acid,
