Demulsifier storage tank 300 is and demulsifier can be transported to tank body 210 by pipeline for storing demulsifier
It is interior, demulsifier can be stirred with waste emulsified mixture and be mixed by the work of blender 220.
Ratio between waste emulsified mixture and demulsifier is 1:0.5~2.
Distillation still 400 is connect with tank body 210, and the waste liquid being stirred in tank body 210 can be by Pipeline transport to distillation
Kettle 400, distillation still 400 can carry out heating distillation to waste liquid, realize that demulsifier and waste emulsified mixture carry out azeotropic.
Condenser 500 is arranged above distillation still 400, and is connect by pipeline with distillation still 400, and distillation still 400 produces
Raw steam can be flowed into condenser 500, and condenser 500 can carry out condensation cooling to steam and form aqueous.
Liquid liquid Separation tank 600, is separately connected condenser 500 and distillation still 400, and condensed aqueous can be flowed into liquid liquid
Liquid liquid Separation is carried out in knockout drum 600, at this moment water phase can sink to the tank bottom of Liquid liquid Separation tank 600, and demulsifier can be suspended in liquid
The top of liquid knockout drum 600, and reflowable in distillation still 400, and is recycled in distillation still 400, until will be in distillation still 400
Waste liquid separation it is clean.
Wastewater collection tank 610 is connected on Liquid liquid Separation tank 600, the waste water for sinking to 600 bottom of Liquid liquid Separation tank can be discharged into
Unified recycling is carried out in wastewater collection tank 610.
And the bottoms in distillation still 400 after distillation can be used as waste lubricant oil regeneration raw material or carry out burning disposal.
In addition, realize the automatic control of the application to improve working efficiency, settling tank 100 and agitating device 200 it
Between pipeline, the pipeline between agitating device 200 and demulsifier storage tank 300, agitating device 200 and distillation still 400 it
Between pipeline on be respectively equipped with control valve, and the application further includes a control switch, and control switch is separately connected each pipeline,
It is closed for controlling the logical of each pipeline.
Here is the specific work process of the application:
(1) waste emulsified mixture is uniformly flowed into settling tank 100 first and is settled and is filtered, removed solid in waste emulsified mixture
Body impurity；
(2) the useless cream after sedimentation filtration is then transported to agitating device 200, and will be broken in demulsifier storage tank 300
