Abstract

The invention relates to filters for water purification in the production and drinking water supply and allows increasing its capacity by increasing the degree of purification of industrial water. The filter contains a vertical cylindrical housing 1, the working chamber of which is filled with a filter cartridge.

4 of granular material and divided into radial-partitioned compartments. In the upper part of the housing there is a feeding pocket with openings 8 for distributing the source water to the sections filtered as it passes through the loading 4 upwards. A tube 9 with a radial nozzle 12 for receiving industrial water, connected by an upper end with a driven mechanism 11 and having an opening 15 at the lower end, passes along the axis of the body. The lower part of the body 1 is separated from the working chamber by a partition 13 and is connected to the feed pocket through pipe 20. In the lower part of the housing 1 there is a device for preliminary gravitational cleaning of wash water from contamination and fixed

on the pipe 9 mesh filter element 14 for further cleaning. industrial water from pollution. The device for preliminary gravitational purification of industrial water is made of a baffle disk 23 with concentric corrugations and a package of concentric cone-shaped rings 24. During filter operation, one of the compartments of the working chamber, communicated through pipe 12 with the cavity S, is disconnected for regeneration by countercurrent of industrial water. The washed contaminants are carried away with industrial water into the lower part of the housing, where it undergoes a two-stage cleaning and partially returns through pipe 20 to the working cycle, mixing with the initial flow of water. 3 il ..

The invention relates to a device for the purification of water by filtration and is an improvement to the filter according to ed. No. 965459.

The aim of the invention is to increase the filter performance by increasing the degree of purification of flush water.

Figure 1 shows schematically

filter, longitudinal section; figure 2 is a section aa in figure 1; figure 3 - section bb in figure 1.

The filter consists of a hermetically sealed Cylindrical body 1, inside of which on a disk 2 with drainage caps 3 there is a filtering load 4 made of granular bulk material. The filter cavity between the drainage disc 2 and the crutch is divided by radial partitions 5 into sector compartments 6.

A distribution cylinder .7 is installed in the upper part of the filter; on its side surface there are slotted openings 8 connecting the cavity of cylinder 7 with filter compartments 6. Pipe 9 passes along the axis of the filter, which is connected by a 1-0 axis with a drive mechanism 11 consisting of an electric motor and a gearbox. Inside cylinder 7 to pipe 8

A horizontal nozzle 12 is attached, at the end of which there is a bell that fits tightly to the side surface of the cylinder 7. In the lower part of the filter under the partition I3 there is a flat filter element 14 consisting of a perforated substrate and mesh, fixed on the pipe 9, on the side surface There is a hole 15.

Under the grid of the filter element 14 is a funnel 16 with a pipe 17, passed outside of the filter. The area of the voroyka 16 corresponds to the area of one sector compartment 6. The filter is equipped with a nozzle 18 with an injector 19 connected by an overflow pipe 20 with a filter compartment located above the screen element 14. In order to prevent water leaks, the central pipe 9 is provided with gland seals 22.

In the lower part of the housing 1 a device for pre-gravitational purification of industrial water is installed, including a bumper grrizontalny disk 23 with concentric corrugations and a package of 24 concentric conical rings. Disk 23 is located

above the openings 15 for discharging the ambient water at a distance of 10-15 cm from the package of 24 rings.

The rings 24 are located in a package with a gap of 3-5 cm and have a width of 15-20 cm, and the cone-like forming them. Noah is inclined to the vertical at an angle of 20-30 °. To the bottom of the filter housing adjacent the pipe 25 for the withdrawal of sediment.

The filter works as follows.

; The water to be cleaned flows through the nozzle 18 into the distribution cylinder 7 and through the openings 8 into the sector compartments 6. The water is filtered through the granular load, flows through the drainage caps 3 and is purified to the consumer through the nozzle 21.

When filtering water, one of the slit openings is blocked by a nozzle - com 12 that obstructs the flow of water.

dock in the space between them, where the movement of fluid is practically absent. The wavy surface of the horizontal disk 23 provides better sedimentation of impurities by changing the direction and speed of the fluid in the gap between the disk and the plates.

10 Partially purified wash water exits the gap between disc 23 and ring pack 24 and is filtered upwards through mesh element 14. Thereafter, water flows under

15 residual pressure through pipe 20 to injector 19, the pressure in which is significantly less than the residual pressure, and together with the main flow of source water again enters the ultra-high pressure

20 filter.

At the same time, the area of the mesh element 14, located under the funnel 16, is flushed with a reverse flow of filtered water.

The partially cleaned wash water leaves the gap between the disk 23 and the bag pack of 24 rings and is filtered upwards through the mesh element 14. Thereafter, water flows under
