Demulsifier is added in reactor tank, heated constant temperature, and being then turned on supersonic generator, mixed liquor is transferred to settling tank by treated,
Constant temperature is stood, until oil, water, mud three-phase layering.This method combines supersonic treatment with foam metal, enhances super
The cavitation of sound accelerates demulsification process.The problems such as that there are pharmaceutical quantities is big for the method, and energy consumption is high, and dehydration rate is low.
CN207330856U discloses a kind of aging Method for treatment of oil, and this method process flow includes sequentially connected microwave
Heating device, ultrasonic response device, elevator pump and centrifuge etc.；It can be realized under the premise of not needing other ancillary equipments
It is stable to ageing oil, efficiently handle, effectively remove the water and solid impurity in ageing oil.There are equipment investment costs for the method
It is high, take up a large area, the problems such as ageing oil treating capacity is low, process flow is not easy to control.
CN102533581A discloses a kind of ageing oil biological desulphurization microbial inoculum and the method using microbial inoculum processing ageing oil,
Culture, addition and the desulfurization of ageing oil of ageing oil biological desulphurization microbial inoculum are carried out using ageing oil biological desulphurization reactor；Solution
Certainly sulfide bring environmental pollution in ageing oil improves the efficiency of ageing oil taking back and process.The method processing ageing oil is deposited
The problems such as Spawn incubation condition is harsh, biological desulphurization reactor is not easy to control, ageing oil treatment effeciency is low.
It is above-mentioned for aging oil treatment process, either traditional thermochemical method, centrifugal treating method, sedimentation,
Or new type ultrasonic method, microbial treatment method；All exist ageing oil treatment effeciency is low, dosing is big, long processing period,
Process flow is complicated, the problems such as taking up a large area.
Summary of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of a kind of methods of microwave treatment ageing oil, by adding
