Achievable technical result - improving the quality of purification and disinfection of water.

This result is achieved in that the sump in the lower part is provided with a drain bolt, which is located in its center. At the end of the perforated tube, a collector is installed, which is made in the form of a plate turned upside down with a hole in its center, the diameter of which is equal to the outer diameter of the perforated tube. The diameter of the collector is made equal to the outer diameter of the body, and the edges of the collector are made hermetically adjacent to the body. The lower end of the perforated tube is led through the hole in the center of the collector into the upper part of the cavity between the housing and the casing. The direction of winding of the spirals of the deflector and the additional deflector is performed in opposite directions.

Figure 1 shows a device for purification and disinfection of water, figure 2 - the same, top view.

The water purification and disinfection device comprises a body 1 provided with a cover 2 with ledges on its lower surface, ultraviolet light-emitting diodes 3 installed on its inner surface, ultrasound emitters 4, a sump 5 made in the form of a hollow hemisphere, centered down. The sump 5 is connected to the casing 6 by means of a threaded connection. In the lower part of the sump is equipped with a drain bolt 7, which is located in its center. A hermetic casing 6 is installed outside the housing 1, repeating the shape of the housing 1.

The device for purification and disinfection of water also includes an outlet pipe 8 installed in the cover 2, a perforated tube 9 vertically installed in the body 1, at the end of which a collector 10 is installed, made in the form of a plate turned upside down with a hole in its center, the diameter of which is equal to the outer perforated tube diameter. The diameter of the collection 10 is equal to the outer diameter of the body 1, and the edges of the collection 10 are hermetically sealed to the body. The lower end of the perforated tube 9 through a hole in the center of the collector 10 is led into the upper part of the cavity between the body 1 and the casing 6 and is tightly fixed with a plug 11 adjacent to the collector 10. A deflector 12 is installed on the perforated tube 9, made in the form of a logarithmic spiral. On the deflector 12, a plate 13 with perforated edges is installed upside down, the outer diameter of which is equal to the inner diameter of the body 1.

The device for purification and disinfection of water also includes a filter element 14, made in the form of a cylinder, and an inlet fitting 15. The inlet fitting 15 is tangentially installed in a horizontal plane in the upper part of the casing 6. Opposite the inlet fitting 15, an inlet pipe 16 is tangentially installed. between the body 1 and the casing 6 there is an additional deflector 17, made in the form of a flat spiral, the width of which is equal to the distance between the casing and the casing. Ultrasonic emitters 4 are installed on the inner surface of the casing 6. The winding direction of the spirals of the deflector 12 and the additional deflector 17 is made in opposite directions.

Device for purification and disinfection of water works as follows.

Water under pressure through the inlet pipe 16 enters the cavity between the body 1 and the casing 6, where an additional deflector 17 is installed, made in the form of a flat spiral, the width of which is equal to the distance between the body 1 and the casing 6. The additional deflector 17 gives the water a rotational movement around the casing 1 , increasing the residence time of water in the cavity between the body 1 and the casing 6. Here, the water is disinfected using ultrasonic waves generated by ultrasonic emitters 4 located on the inner surface of the casing 6, which cause a cavitation effect that contributes to the destruction of water polluting chemicals and microorganisms. An increase in the residence time of water in the cavity between the body 1 and the casing 6 leads to an increase in the time of exposure to ultrasound on the treated water, which improves the quality of its disinfection. With the rotational movement of water created by the additional deflector 17, large particles of pollution are thrown to the outer wall of the sump 5. Here the water loses its speed, and large particles of pollution move to the lower part of the sump, where they accumulate. At the same time, ozone is supplied through the inlet fitting 15, which is installed tangentially in a horizontal plane in the upper part of the casing 6 opposite the inlet pipe 16. When ozone enters the water, it oxidizes the dissolved ferrous iron in it to ferric iron insoluble in water, and the manganese ions present in water form insoluble manganese dioxide. Ozone also disinfects, discolors and deodorizes water. Then the water through the perforated tube 9 enters the internal cavity of the housing 1, where, with the help of the deflector 12, it is involved in a rotational movement in a logarithmic spiral from the center of the deflector 12 to its periphery. When the water rotates in the deflector 12, the particles of contaminants in the liquid are discarded under the action of centrifugal force to the surfaces of the deflector 12, and, further, to the walls of the housing 1 and fall into the collection 10 of the plate shape.

After the end of the spiral movement in the deflector 12, the water changes its direction of movement, loses its speed and passes through the filter element 14, where it is additionally purified from impurities and insoluble compounds of iron and manganese contained in it. The winding directions of the spirals of the deflector 12 and the additional deflector 17 in opposite directions make it possible to ensure the rotational movement of water also in opposite directions and a greater decrease in its speed after their passage, ensuring greater completeness of the separation of contaminants. Then the water, purified from impurities, enters the space between the upper part of the filter element 14 and the inner surface of the cover 2, where it is additionally disinfected under the action of ultraviolet rays emitted by ultraviolet LEDs 3. The presence of ultraviolet LEDs installed on the inner surface of the cover 2 makes it possible to more effectively disinfect water, since the quality of ultraviolet treatment improves with increasing water purity, and already purified water is processed in the upper part of the device body. After that, the water is removed outside the device through the outlet pipe 8, installed in the cover 2. The contaminants present in the water accumulate in the collector 10 of the plate shape, in the sump 5 and in the filter element 14.

Periodically, the cover 2 is removed, the filter element 14 is replaced, the accumulated contaminants are removed from the plate-shaped collector 10 and from the sump 5, having previously unscrewed the drain bolt 7. Improving the process of separation and subsequent removal of contaminants improves the quality of water purification.

Supplying the sump in the lower part with a drain bolt located in its center, installing a collector at the end of the perforated tube, made in the form of a plate turned upside down with a hole in its center, the diameter of which is equal to the outer diameter of the perforated tube, making the diameter of the collector equal to the outer diameter of the body, performing the edges of the collector are hermetically adjacent to the body, the removal of the lower end of the perforated tube through the hole in the center of the collector into the upper part of the cavity between the body and the casing, as well as the winding directions of the spirals of the deflector and the additional deflector in opposite directions, allows for high-quality purification of water from impurities and contained in it soluble compounds of iron and manganese and at the same time disinfect it.
