Description

The invention relates to devices for filtering water and can be used in the purification of high-altitude natural waters for water supply purposes.

The purpose of the invention is to improve the quality of regeneration and reduce the flow rate of wash water.

In FIG. 1 shows a filter, cross section; in FIG. 2 is a section along AA, in FIG. 3 (bounding frame).

The filter consists of a housing with longitudinal 1 and transverse 2 side walls, a pocket 3 with pipelines for supplying the source water A and removing the wash water 5, a granular charge 6 placed inside the housing and a regeneration device including a carriage 7 mounted for longitudinal movement attached to it a vertical pipe 8 connected to a horizontal water distribution pipe 9 with a system of flushing tubes 10 equipped with nozzles 11, a flexible hose 12, one end of which is connected to the vertical pipe 8, and the other to a means for supplying washing water 13. The regeneration device is provided with a restriction frame 14 with a closed vertical end for washing water 15 with a mesh 16 and an overflow edge 17. The container 15 is made with a horizontal slit 18 at the bottom of the wall 19 in front of the grid 16 and connected by a pipe 20 with a vertical pipe 8. The restriction frame 14 is mounted on a horizontal water distribution pipe 9 using horizontal strips 21 and vertical posts 22. The overflow edge is made of. bora.plastin 23. For removing purified water from the filter housing conduit 24 is mounted.

The filter works as follows.

. In the filtering mode, water is supplied from the water supply source to the filter housing through the feed water supply pipe 4 and pocket 3. At the same time, the valve on the pipeline for removing the wash water 5 is closed. Water passing through the granular charge 6 is purified and discharged via line 24 to the consumer.

After contamination of the granular charge 6, its regeneration is carried out. To do this, close the valves in the pipelines 4.24 and open the valve in the pipeline to drain the wash water 5. From the means for supplying the wash water 13 through the flexible hose 12, water is supplied under pressure to the vertical:; pipe 8 of the regeneration device. From a vertical pipe 8 water

enters the pipeline 20 connected to the vertical tank 15, and into a horizontal water distribution pipe 9 with a system of washing pipes 10. Water jets,

exit from the nozzles 11 of the washing tubes 10 with a high pressure, erode the granular load 6 and wash it from pollution. The washed away contaminants are carried by ascending jets onto the loading surface. At the same time, the water flow coming from the pipeline 20 into the tank 15 transforms into a flat stream distributed over the width of the restriction frame 14, and changing the direction of movement by 90 °

through the horizontal slit 18.

 When exiting the slit 18, the flow captures the pollution washed from the granular load 6 and transports them within

restrictive frame 14 into pocket 3. When

In this case, the grid 16 mounted on the container 15 behind the slit 18 prevents erosion of the granular load at the outlet of the flow from the slit 18. The overflow edge 17 allows, due to a change in its height, to vary

the speed of movement of the transverse flush flow, creating an optimal mode of removal of washed contaminants from the erosion area of the granular load, which depends on the ratio of the velocities of movement of the flush

flow and regeneration devices. In addition, the overflow edge 17 prevents the transfer of loading grains into pocket 3.

By moving the regeneration device along the filter housing, the entire granular charge is regenerated in this way. After regeneration, by supplying a small amount of water through the pipeline for supplying the source water 4, the residual contaminants are washed off from the bottom of the pocket 3,

Then, the valve in the pipeline for draining the wash water 5 is closed, the valve in the pipeline 24 is opened and the filtering cycle is repeated.

An advantage of the device according to the invention is that when the granular charge is regenerated, a narrow direction is created); (to the width of the loading washout area) a transverse wash-off flow with a variable speed of transporting washed wastes along the shortest path without removing the loading grains. As a result, the flow rate of the wash water is reduced, the quality of the regeneration is improved, and the time of its holding is shortened.
