Description

The invention relates to the technique of separation treatment of large volumes of wastewater containing oil products emulsified in them in low concentrations, and can be used in wastewater treatment plants before their physicochemical treatment.

The purpose of the invention is to increase productivity.

To separate emulsified oil from large volumes of wastewater, it is necessary to adhere it to the material of the inner shell, which is achieved by vibrating it with weights, and rings of elastic material are used to separate the water from the oil; increasing the inertia of the separation products.

Figure 1 shows a device, a longitudinal section; figure 2 - node I in figure 1.

The wastewater treatment device comprises a housing 1 with a sewage supply pipe 2 mounted in a housing 1 on a drive shaft 3, a rotor comprising two disks 4 and 5 mounted one above the other with the formation of a chamber 6 connected to the sewage supply pipe 2 and having partitions 7 with windows 8 for overflowing the latter, and two cone-shaped non-rigid shells - the outer 9 and inner 10, freely suspended by a smaller base on the disks 4 and 5 with the formation of an annular gap 11 connected with the chamber 6 between the disks 4 and 5, and so that it is free chrome and 12 non-rigid inner shell 10 is located lower than the free edge 13 of the outer. On the outer surface of the portion of the inner shell 10, located under the free edge 13 of the outer shell 9, rings 14 are made of elastic material, and on the inner surface of the inner shell 10 there are loads representing pockets 15 filled with bulk material 16. The housing 1 is made with a pipe 17 of the outlet of the iodine and a pipe 18 of the drain of petroleum products.

A wastewater treatment device operates as follows.

Wastewater containing oil products emulsified therein, through a pipe 2 enters the chamber 6 between the disks 4 and 5, rotating on the drive shaft 3, and flows through the windows 8 between the partitions 7 with rough separation into water and oil products and enters the annular a gap 11 between the outer 9 and the inner 10 shells, where density separation occurs. Petroleum products having a lower density are located on the surface of the inner shell

10, and water in the outer layer under the shell 9 .. Under the action of vibrations that create loads from pockets 15 filled with bulk material 16, oil products enter

in adhesion with the material of the inner shell 10, and the use of goods with. filling the pockets 15 with bulk material 16 makes it possible to control the vibration effect on the wastewater. Upon exit

from under the edge 13, water having a traction force with oil less than the traction force of the latter with the material of the shell 10 is torn off and is discharged from the housing 1 through the nozzle 17 in the spray torch.

water is promoted by rings 14 made of an elastic material which does not prevent deformation of the shell 10 under the influence of loads, in the form of pockets 15 with bulk material 16. Oil products are not

retagagate under tangential

component of the centrifugal force to the free edge 12, and on the rings 14, their mass accumulates and when the inertia force of the oil mass 5 is reached. of the products more than the cohesive force of the petroleum products with the material of the shell 10, they are torn off and they are withdrawn from the housing 1 to the tangential pipe 18 in the spray torch.

0 The technical and economic effect is that the device provides high productivity, in the absence of conditions for clogging and the need for disassembly.
