Description

The invention relates to devices. for continuous separation from water solutions of oils, greases and oil products and can be used in automobiles in special centers for technical maintenance of vehicles and in other industries.

Closest to the invention according to. the technical essence and the achieved effect is a device for the continuous separation of oils from aqueous solutions, comprising a housing for emulsion inlet and oil outlet pipes, a cylindrical container with purified water outlet pipe 15 and a septum in the form of an inverse cone [1].

However, the additionally installed reverse cone does not provide from -20 the separation of light phases from the aqueous solution and they partially penetrate the heavy phase through the opening of the truncated cone.

The purpose of the invention is to increase the separation efficiency and the quality of purified water.

This goal is achieved by the fact that the oil drain pipe is placed in a cylinder-conical tank, while 30 the device is equipped with an inclined partition placed between the pipes for cleaned water and oil drain, an additional cylinder-conical tank and a partition in the form of a reverse truncated cone, placed under the additional tank, with a valve stem and ring air ducts located in the bases of the conical parts of the cylindrical tanks and partitions.

The drawing shows a device, General view.

The device includes a housing 1 with a conical bottom and a hatch 2, in the upper part of the housing there is a cylinder-conical tank 3. The tank 3 is divided by an inclined partition 4 into two tanks 5 and 6. The upper of them is connected to the pipe 7 of the oil drain, and the lower one to the pipe 8 of the drain purified water.

Reverse truncated cones 9 and 10 with valves> panes are located under the lower tank. 11 and 12, the Device is equipped with an additional cylindrical tank with a cylindrical 13 and conical .14 parts.

A pipe 15 connected to the atmosphere is fixed on an inclined partition 4 in its center, through which a rod 16 passes, connected to the actuator 17 and valves 11 and 12.

In the middle part of the device there is a pipe 18 for supplying air to the pipelines 19 connected to the truncated cones. The device also includes a louvre grille 20 and a pipe 21 for supplying emulsion with a perforated pipe 22.

The walls of the housing 1, the cylindrical part 13 of the tank and cylindrical. tanks 3 form oil traps 23 and 24.

The device operates as follows.

Through pipe 21, an aqueous solution with 15 emulsified organic phases is fed into pipe 22 and passes through its openings.

The heavy organic phase under the influence of gravity is deposited on the conical bottom of the housing 1 and is periodically removed through the hatch 2.

When an aqueous solution passes through the louvre grille 20, the speed decreases and the direction of flow changes, which contributes to the coalescence of droplets of the light organic phase.

Particles of oil, grease, and oil products, falling under the lower truncated: 10 ° C 10, float, and the aqueous solution, 30 passing through the labyrinth formed by the reverse truncated cones 9, 10 and the conical part 14, is completely freed from organic phases, and the tank enters 6 and through pipe 35 8 by gravity (or due to vacuum) is discharged into the collection.

The light phases, emerging, fill the oil traps 23 and 24, which enter the tank 5 and are discharged through the pipe 7.

In order to accelerate the separation of organic phases from the aqueous solution and to prevent them from entering the tank through the pipe 18, compressed air is supplied into the annular pipes with openings 19, which are fixed around the perimeter of the upper part of the inverse truncated cones.

In order to remove possible solidification of ί solid particles in the lower part of the truncated cones 9 and 10, the clagans 11 and 12 connected to the rod 16 passing through the pipe 15 fixed on the inclined partition 4 are periodically opened by the drive 17.

The invention can significantly improve the quality and efficiency of the separation of light phases from aqueous solutions.
