At present, Yuyuan oil separation and lifting equipment mainly uses the function of pressure. The sewage that needs to be separated enters the oil-water separator through the pressure of the pump, the sewage diffuses through the nozzle, and the larger oil will enter the oil collection chamber on the left and reach the top. At the same time, the sewage containing small oil droplets will enter the corrugated plate coalescer, where the small oil droplets will coalesce into large oil droplets and enter the right oil collection chamber. The smallest oil drop sewage will pass through a filter, and the impurities in the sewage will be removed, and then it will reach the fiber polymerization kettle. In the fiber polymerization kettle of Jinyuan oil separation and lifting equipment, fine oil droplets gather into large oil droplets as mentioned above, where they are separated from water. After separation, the washing water will be discharged. The oil droplets previously accumulated in the left oil collecting chamber and the right oil collecting chamber will also be discharged through the solenoid valve, and the oil on the fiber polymerizer will be discharged manually.
