Background
The industrial waste oil recovery process produces oily sewage which must be properly treated before being discharged. The oily wastewater treatment method has various treatment methods and treatment equipment types, the oil separation is performed by adopting an oil separation tank which is most commonly used for oil separation, the oil separation tank performs oil-water separation by using density difference between oil and water, the method is widely applied to a water treatment process of an oil refinery, plays an important role in removing oil in wastewater, and the gravity separation method is a method for separating by using the density difference of water. The method can be used for removing oil particles with the particle size of more than 60 mu m and most of solid particles in wastewater. The most common apparatus for gravity separation is the oil interceptor. It utilizes the characteristic that oil drops are lighter than water to separate oil to the water surface and skimming. The oil separation tank is mainly used for removing floating oil.
The emulsified oil can be effectively separated after demulsification, and besides the demulsifier, the demulsifying agent is added in the demulsifying of the emulsified oil, so that the small oil drops in part of the emulsified oil can be promoted to be converged into large oil drops by increasing the temperature.
The industrial waste oil recovery production line needs to use a boiler, and the flue gas of the boiler can be emptied after being properly treated.

One specific design is as follows.
The separating box 2 is divided into a first bin 6 and a second bin 11 through a bin partition plate 9 with a through hole 10, so that the cleaning is relatively divided, and drainage, oil outlet and sludge discharge are facilitated.
A plurality of oil separation plates are arranged in the separation box 2 at intervals and comprise an oil separation plate A3A, an oil separation plate B3B and an oil separation plate C3C, the oil separation folded plate 8 basically plays the same role, and the through holes 10 are water passing channels basically.
Oil barriers employing such techniques can of course be used, but still suffer from the following disadvantages:
a, only floating oil can be treated, and emulsified oil which is not demulsified cannot be treated.
And B, the oil separation device needs to be heated additionally to prevent freezing in winter.
