Abstract

The invention relates to devices for purifying water from petroleum products. Purpose of the invention is to reduce the cost of operating the device. The device comprises a housing, an oil collection pipe for supplying source water, removal of oil products and clarified water, an elastic-elastic load placed by two perforated partitions, the bottom of which is foamed, and the top is provided with a drive of its vertical movement in the form of an annular chamber of variable volume, connected to a pipe for supplying raw water. During regeneration Loading the t it is produced forced off by feeding untreated water into the variable volume chamber. When the load is lowered down during compression, the clarified water, which is located beneath it in the cavity, squeezes the oil products out of the load up, the latter is then passed into the oil tank, 1 sludge.

Description

The invention relates to equipment for the separation of liquids and can be used to purify water from oil-containing impurities.

The purpose of the invention is to reduce the service life of a liquid separator,

The drawing shows a liquid separator

The liquid separator comprises a housing 1, an oil tank 2 with a pipeline 3 for discharging oil products, pipes 4 and 5 for supplying the source water and withdrawing the primary water and filtering the load to 6,

1 At the entrance of the pipeline 3 of the tank 2, guides 7 are installed with pop-8 spherical shapes placed between them serving as a shut-off valve. The density of the float is lower than the density of the oil and less dense.

{The filtering load 6 is made of an elastic plastic material (porous rubber, foam rubber and ToPo) and is placed between two perforated partitions 9 and 10, made with the possibility of vertical movement. Lower the partition 10 rests on the shelves 11 of the housing 1 through the compression springs 12. Upper the partition 9 it is driven by its vertical movement, which is made in the form of an annular chamber 13 formed by the housing wall, a horizontal ring 14 fixed on the housing wall, and a corrugated cylindrical shell 15 in The upper part of which is attached to the ring 14, and the lower - to the partition 9o

The annular chamber 13 is connected to the nozzle-4 of the feed water supply through the valve 16,

The pipe 4 is equipped with a valve 17, and the pipe 5 - valve 18o

The partition 9 is provided with a sealing lip 19, reinforced along the perimeter,

Between overcrowding 10 and the bottom of the housing 1 there is a cavity 20 for clarified water.

Liquid separator works in the following way.

Water 4 вода spe3 polluted with oil products пат pipe 4 enters housing 1. Large droplets of oil products populate in the oil tank 2 and accumulate in it, and fine particles are retained.

watered by filtering load 6 when filtering water from top to bottom. Purified water is discharged through the nozzle. As the liquid separator works, oil products accumulate in the oil tank 2, and the pores of load 6 are filled with coagulated drops of oil products

To regenerate the load 6, it is released. To do this, the valves 17 and 18 are closed. The valve 16 is opened and the initial water under pressure enters the chamber 13o.

The baffle 9 is lowered downward, and the corrugated shell 15 is expanded. The load 6 is compressed, as a result of which the partition 10 is lowered down and compresses the springs 2o

Due to a decrease in the pores of the load, the oil products are squeezed and lifted upwards by a stream of clarified water, which is formed due to the displacement of water from the cavity 20 as a result of lowering the load with the partition 10. At the same time, the water flow washes the load pores. load 6, rise to the oil collector 2o. Then open the valve 17 °. The water pressure in the housing 1 increases and the oil products are forced out into the pipeline 3 until the float 8 rises up along the guides 7 and closes the inlet The opening of the pipeline G In this case, the oil products are completely removed from the oil tank 2, however, water does not flow into the pipeline 3.

Next, the valve 18 is opened, the water pressure in the housing 1 drops, as a result of which the water from the chamber 13 is displaced through the nozzle 4 in the housing 1 under the action of elastic loading forces b, restoring the initial volume of the corrugated shell 5 n of the spring 12

Next, the filter cycle is repeated.

The technical and economic efficiency of the proposed liquid separator consists in reducing the cost of its operation up to 35-40% as compared with the known by eliminating washing the filter with fresh water from an additional source by replacing it with the release of the initial energy of the liquid and displacing upwardly detained oil products. clarified water under load at

lowering the latter in the direction of the bottom of the body during compression. This is ensured by installing a filter made of elastic material made of elastic material between two perforated partitions made with the possibility of vertical movement under the action of the drive of the upper partition.
