Abstract

The invention can be used to purify natural, waste and recycled water. The elastic body 1 of the device is conical in shape and has a two-thread conical auger 2 with variable pitch, the blades are connected to a current source 9. Between the blades there is a filtering load 3 of elastic material. The housing is connected by the discharge nozzles of the contaminated load 6 and the supply of the regenerated load 7 with a capacity of 8, in which the loading is regenerated. The container 8 is provided with a hollow perforated piston I1. Due to such an implementation, the filter is continuously operated without stopping it to regenerate the load, and the combined electrical and hydrodynamic effects on. soil particles provide an increased effect of their deposition. 1 hp f-ly, I ill. €

Description

placed in housing 1. Between the loop-15 between the blades of the electrodes, the intensity of the electric field decreases and the effect of electrical effects on the particle retention decreases. Thus, the efficiency increases.

The screw auger 2 has a filter loading 3 (e.g., pieces of foam rubber). To the housing 1 attached nozzles 4 supply and outlet 5 of the liquid. Cor

Pus 1 is connected by water purification nozzles.

A known filtering load 6 and supplying the regenerated filtering load 7 with a capacity of 8, in which the loading is regenerated. The surface of the blades of the screw 2 is made of conductive material and each surface is connected to the opposite pole of the current source 9. The container 8 is made in the form of a cylindrical housing 10, in which a hollow piston 11 with openings 12 and a discharge pipe 3 is located. A supply nozzle 6 for supplying contaminated filter media is attached to the container

through the valve 15. In addition, a tap 16 is connected to the tank 8 from the nozzle 5 of purified water through the valve 17 to flush the regenerated load.

The device works as follows.

Contaminated water through pipe 4 is fed into the device. When moving from the smaller base of the housing to the larger one, the water is filtered through the load 3, spiraling between the blades of the screw 2 connected to the current source 9. Contaminants are retained in the pores under the action of a sum of electrical effects and hydrodynamic forces.

When the water moves in a cone in a spiral, the filtration rate decreases and the effect of arresting cr particles increases. Purified water is discharged from the device through a pipe 5 located at the larger base of the housing 1. At. auger rotation 2 loading50

The proposed device is characterized by high efficiency due to continuous operation without stopping the washing of the filter loading, which is ensured by the presence of a conical auger with variable pitch, which is placed in an elastic conical body, as well as a filter loading between the screw blades and the regeneration device.

Due to the complex electrical and hydrodynamic effects and the continuous operation of the device, energy efficiency is increased by; with a prototype.

Claims (2)

1. A device for water purification, including a housing with nozzles of flow. Regeneration of an elastic load is carried out as follows. The most contaminated layers of the loading are injected by screw 2 through pipe 6 through valve 14 into container 8. The piston I1 is in the lower position. When the piston moves upwards, the load is compressed and the contaminated water is drained with sediment through the opening 12 through the pipe 13 of the piston. When the piston moves downward, the load in the tank is again saturated with water, and when the piston moves upward again, it is washed. This procedure is repeated several times. Next, open the slide ki 17,15 and through the tap 16 into the tank 8 purified water flows through the nozzle 6 through the filter loading to the filter. The proposed device is characterized by high efficiency due to continuous operation without stopping the washing of the filter loading, which is ensured by the presence of a conical auger with variable pitch, which is placed in an elastic conical body, as well as a filter loading between the screw blades and the regeneration device.
