Composite-method oil removing apparatus

Abstract

The invention provides a composite-method oil removing apparatus which employs composite principles of aggregation and oleophobicity, belonging to the technical field of oil-water separation and filtration. The apparatus comprises a water inlet, a water inflow chamber, an oil collecting chamber, a floating oil chamber, an oil outlet, an oleophobic chamber, a shell, a drain outlet, a clear water chamber and a water outlet, wherein raw water enters into the water inflow chamber from the water inlet, impurities in the water deposit on the bottom of the water inflow chamber and are discharged from the drain outlet, then the water enters into the oil collecting chamber, an oleophylic and oil-accumulating material is disposed in the oil collecting chamber, dispersed oil in the water is aggregated to form large-grained oil droplets which enter into the floating oil chamber, the water in the lower part of the floating oil chamber enters into the oleophobic chamber, an oleophylic and oil-separating material is disposed in the oleophobic chamber to further obstruct residual oil in the water, obtained clear water enters into the clear water chamber and is discharged from the water outlet, and floating oil is discharged from the oil outlet. The composite-method oil removing apparatus provided by the invention can realize backwashing, removes impurities and oil without addition of additives and guarantees that the properties of original liquid maintain invariable; and usage of a plurality of the oil removing apparatuses in series connection enables oil to be thoroughly removed, so the oil removing apparatus has wide market prospects.

Description

【Technical field】 [0001] The invention relates to a complex degreasing device, which is a degreasing device using a composite method of aggregation and oleophobicity, used for oil-water and impurity separation, and belongs to the technical field of oil-water separation and filtration. 【Background technique】 [0002] Traditional oil-water separation is generally handled by a single method, such as walnut shell oil-water separator, ceramic filter element filter, etc. Walnut shell oil-water separator only uses the oleophobic properties of the material to achieve oil-water separation, and the oil-water separation effect is poor. Frequent material replacement, high cost, ceramic filter elements are easy to block, high operating costs, and narrow application range. 【Content of invention】 [0003] The object of the present invention is to provide a compound degreasing device, which uses the oleophobic and oleophilic properties of materials to achieve the purpose of oil-water sepa...
