A disadvantage of the known installation for water treatment is the complexity of its design, the instability of the installation due to the conical shape of the lower part of the housing.

The task to which this utility model is directed is to simplify the design of the installation and increase convenience during its operation.

The essence of the utility model lies in the fact that in the installation for water purification, containing a vertical sealed housing made in the form of a coaxially located open top cylinder with a bottom and an outer cylinder, to which a confuser is rigidly connected at the top, a conical shell mounted in the case inner cylinder a pressure filter with bulk loading, located coaxially to it in the space between the cylinders, a sump with thin-layer elements.

Bulk loading of the pressure filter can be made from the lower layer of quartz sand and from the upper layer of crushed anthracite, the ratio of the thicknesses of which is 2 ... 3: 1

The above differences of the utility model can simplify the design of the installation for water purification.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a water treatment plant, longitudinal section, FIG. 2 - same general view

Installation for water treatment, contains a vertical sealed enclosure 1, made in the form of coaxially located open from above

an inner cylinder 2 with a bottom 3 and an outer cylinder 4, which are connected rigidly at the top of the confuser 5, at the bottom there is a conical shell 6, a pressure filter 7 with a bulk charge installed in the inner cylinder 2 of the housing, located in coaxial with it in the space between the cylinders 2 and 4 of the settler 8 with thin layers elements, conical chamber 9 flocculation, nodes 10 and 11 of the inlet and outlet of water, hatches 12 and 13 loading - unloading of filter material.

The inner cylinder 2 is made of a greater height than the outer cylinder 4. The formed conical shell 6 is located to the generatrix of the inner cylinder 2 at an angle of 40-50. The conical shell 6 is rigidly connected with

the inner cylinder 2, forming inside the camera 9 flocculation. The inner and outer cylinders 2 and 4 at the top are rigidly interconnected by means of radial rods 14. At the bottom of the inner cylinder 2, a hatch 13 for unloading the filter material is installed. On the vertical axis of symmetry on the confuser 5, a hatch 12 for loading the filter material with a diameter equal to the diameter of the inner cylinder 2 is installed. Thin-layer elements of the sump 8 are made in the form of spiral polymer tubes 15.

Bulk loading of the pressure filter 7 can be performed from the lower layer 16 of quartz sand and from the upper layer 17 of crushed anthracite. To the node 10 of the supply of source water for cleaning is connected to the pipe 18 of the discharge of contaminated water. To the node 11 of the drain of purified water is connected to the pipe 19 for supplying washing water.

Installation works as follows.

The source water treated with the reagents is fed for purification through the unit 10 to the flocculation chamber 9, in which the chemical reactions end and intensive coagulation and flocculation take place. Next, the water enters the sump 8 with thin-layer elements, in which the main amount of suspended solids is removed from the water due to the thin-layer sedimentation of the suspension on the surfaces of the tubes 15 and due to the centrifugal separation of the suspension and water. Part of the sediment under the influence of gravitational forces, due to the inclined position of the tubes 15 slides into the flocculation chamber 9.

Water, leaving the thin-layer sump 8, rises up to the confuser 5, overflows through the upper edge of the inner cylinder 2 and changes the direction of movement 180 ° downward, entering the pressure filter 7. When the water flow turns through 180, the water flotated on air bubbles and emulsified substances float up under the confuser 5 and hatch 12, from where they are removed during washing. The presence of the confuser 5 provides an even distribution of water on the surface of the inner cylinder 2 and creates conditions for the stable operation of the pressure filter 7 and filtering the water at high speeds. In filter 7, water is filtered through bulk loading, for example, through crushed anthracite layer 17 and quartz sand layer 16, and already purified, clean water is discharged to the consumer.

The installation is flushed by supplying flushing water through the pipe 19 in the opposite direction, first to the filter 7 from the bottom up and then through the tubes 15 of the sump 8 from top to bottom, through the chamber 9, washing out the sediment, and to drain the contaminated washing water through the pipe 18.

The design of the installation according to the utility model allows you to quickly replace the bulk load of the filter 7, for this through the hatch 13 unload the old bulk load, and through the hatch 12 load a new bulk load.

The simplicity of the design of the proposed installation for water purification makes it convenient for this: plowing. The installation has become stable due to the fact that

it rests on the foundation with a large area of cylinder 2 and the center of gravity of the installation has moved down in height. Compared with the prototype, the installation has become more compact and smaller in height while maintaining high performance.
