Abstract

The invention relates to an arrangement for the treatment of wastewater, mainly oily, and to improve the quality of regeneration. The pressure filter consists of a cylindrical body 1 installed in the body at a distance from its walls of a cylindrical chamber 2 of thin elastic material with an elastic filter charge 8 placed in it. In this device, the regeneration of the load (spin) is carried out as a result of moving the 3, and due to the ordering lateral compression of the chamber 2, which has a rigid ring 10 in the central part. The regenerate is removed by a hollow element 12 having drainage holes 13 in the lower part and provided with a pipe a bout 15 for withdrawing the regenerate, telescopically entering into the branch pipe 16 for withdrawing the regenerate. 2 Il.

The invention relates to wastewater treatment plants, mainly oily, and can be used to clean the washing water of automobiles and railway transport, that filter, as well as to increase dense, ballast and other water.

The purpose of the invention is to improve the quality of regeneration.

FIG. 1 shows a pressure filter, a longitudinal section, at the time of filtration; in fig. 2 - the same at the time of regeneration.

The pressure filter consists of a cylindrical cornea 1, inside of which is a cylindrical chamber 2, the completion of the filter element 2, it is possible to maintain some pressure in the filter housing 1, controlled by valve G. After saturating the filter loading with oil products, valves A and B are closed, O and valve B opens (Fig 2). Due to the external pressure of water regulated by the valve D, pressure is pumped into the filter housing 1, and the filter loading 8 is pressed out, as if by a thin, elastic water-proof by compressing it with a chamber 2 of elastic material (for example, rubber). ) of the material, and due to the interchange, connected to the pistons 3, is fixed — the pistons 3. Regenerate, at the same time,

on the nozzles for the recovery of the regenerator-squeezed out of the load and removed by the 4 and removal of the filtrate 5. the drain holes 13 in the hollow

The nozzles 4 and 5 are arranged in this way through the pipe 15 and the nozzle 16. So that they have the possibility of a free 20. After that, the pressure from the movement relative to the filter housing of the filter housing is relieved and all the taps return to their original position. The filter element under the action of its own elasticity and under the action of water supplied by the load 8 (for example, polyurethane foam). On filtering through the pipe 4, taking Pistons 3 are equipped with distribution and the original form.

The pressing can be repeated several times, after which the filtering can be performed again until the next loading of 8 with oil products. The whole process of filtration and repo guides 6 and removed from the housing 1 through the glands 7. The elastic chamber 2 is filled with elastic filtering

systems 9.

In the central part of the filtering chamber 2 there is a rigid ring 10,

coupled to pistons 3 by flexible couplings, Q generation can be automated, m 11. At the center of the ring 10 is located

Invention Formula The hollow element 12 is streamlined in shape, having drainage holes 13 in the lower part, and is fixed on the ring by adjustable flexible connections 14, which allow it to be centered. The drainage element 12 is provided with a diverter tube 15, which is telescopically included in the nozzle 16 for withdrawing the regenerate. For the purpose of creating pressure on the regenerant. A filter for cleaning oily waste water, containing a cylindrical housing with a lid and a bottom, nozzles for withdrawing regenerate and purified WATER, attached respectively to the bottom and a cap, a nozzle for feeding purified water attached to the nozzle for evacuating the regenerate, the walkie-talkie (squeeze) layer of the elastic filter loading 40 of the elastic filter loading, the casing 1 contains a fitting 17 for a working agent connected to the elastic cylindrical water, for example, water on the shell And a branch pipe for supplying a workers otzhim.go agent into the body during regeneration. The filter also has a lid 18 and characterized in that, in order to increase the bottom 19, the pipes 4 and 5 are attached. neither regeneration quality, it is equipped with a piston, respectively, to the bottom and the lid, and the patrons installed inside the housing on the side 20 for supplying the purified water to the branch pipes attached to the lid and the days are connected to the outlet 4 to drain the regenerated water, and a hollow streamlined element with P-drainage holes secured in The filter works as follows. After the beginning of filtration, the taps A and B, with a rigid ring having diameters, taps B and D are closed. The scoop is equal to the diameter of the shell, while the water being drawn through the nozzle 4 enters the hollow element has a pipe, telescopically a filter through the distribution system 9. connected to the nozzle for removal of the recirculation passage through the elastic filtering gap. load 8, particles of petroleum products are adsorbed on it, and purified water is discharged to the pipe 5.
