Abstract

The invention relates to the treatment of wastewater in the oil and petrochemical industry and improves the performance of the device. The device for purifying oil-containing water includes a chamber in which a layer of contact mass is placed of oil, inclined parallel plates mounted at the oil-water interface, with the upper surface of the plates made hydrophilic and the bottom surface hydrophobic. The proposed device provides a higher rate of filtration through a layer of oil with high cleaning efficiency, which makes it possible to increase the productivity of the device. 1 il.

Description

The invention relates to the removal of oil-containing water and can be used to clean oil-field wastewater from oil and mechanical impurities for use in the reservoir pressure maintenance system.

H, i the drawing shows the device, General view

An oil line contains a chamber 1 in which the contact mass of oil 2 is located. At the interface of oil-water 3, there are pair of inclined plates 4, the upper surface of which is hydrophilic (enameled iron plate) and the bottom hydrophobic (hydrophobizapes were calculated by methylation of the lower surfaces of enameled iron plates with pairs of grimethylchlorosilane at 150–180 ° C for 12 hours) For uniform distribution of the original oily water, the distributor 5, for , Lovlennoy oil - patrchbok 6, and for draining) h i ton water - 7 patrchbok

The device is working with.

The original oily water is evenly distributed over the volume of contact mass from oil. At the three-phase oil – water – hydrophilic surface section, a coalescence of water droplets with a water layer occurs, and at the three-phase oil – water interface,

drops of oil with a layer of oil.

The insertion of plates onto the oil – water interface makes it possible to significantly shorten the life of oil and water droplets, and thus prevent the filter layer from stretching. Stretching the filter bed is the main reason for decreasing the productivity and efficiency of cleaning oily water by passing through no contact masses.

The least stretching of the filtering layer is achieved when it is placed at the interface between oil and water plates, the upper surface of which is made hydrophilic, and the bottom surface is hydrophobic.

A drop of water, wetted by a hydrophilic surface, rolls down the sloping tip
