Description

The invention relates to mechanical engineering and can be used for purification and disinfection of water.

Known device for purification and disinfection of water [Device for purification and disinfection of water. - Patent RU No. 144624. - Publ. August 27, 2014, Bul. No. 24], Patent RU No. 189132. - Publ. 05/13/2019, Bul. No. 14], containing a housing equipped with a cover, a filter element, an inlet fitting, a sump, an outlet pipe installed in the cover, a ring installed in the upper part of the housing, the outer surface of which is in contact with the inner surface of the housing. UV LEDs are installed on the inner surface of the cover. The sump is made in the form of a hollow hemisphere, centered downward, with the inlet fitting installed in the center of the sump. A perforated tube is vertically installed in the body, connected to the inlet fitting, a deflector made in the form of a spiral is installed on the tube, a round plate is installed on the deflector. The ring is installed above the plate, on the lower surface of the cover there are ledges. The filter element is installed between the ring and the ledges and is made in the form of a cylinder, the diameter of which is equal to the inner diameter of the body.

The disadvantage of this device is the low quality of water purification and disinfection.

The achieved technical result is an increase in the quality of water purification and disinfection.

The specified result is achieved in that a sealed casing is installed outside the housing, which repeats the shape of the housing. The lower end of the perforated tube is installed in the cavity between the body and the casing. The inlet fitting is installed tangentially in the horizontal plane in the upper part of the casing. Opposite the inlet nozzle, the inlet nozzle is tangentially installed. An additional deflector is installed in the cavity between the body and the casing. Ultrasound emitters are installed on the inner surface of the casing.

FIG. 1 shows a device for purifying and disinfecting water, FIG. 2 - the same, top view.

The device for cleaning and disinfecting water contains a housing 1, equipped with a cover 2 with ledges on its lower surface, UV LEDs 3 installed on its inner surface, ultrasound emitters 4, a sump 5 made in the form of a hollow hemisphere facing center downward, an outlet 6, installed in the cover 2, vertically installed in the housing 1 perforated tube 7, mounted on the tube 8, made in the form of a logarithmic spiral, mounted on the baffle 8 bottom down plate 9 with perforated edges, the outer diameter of which is equal to the inner diameter of the body 1, filter element 10 , made in the form of a cylinder, as well as an inlet connection 11. Outside the housing 1, a sealed casing 12 is installed, repeating the shape of the housing 1. The lower end of the perforated tube 7 is installed in the cavity between the housing 1 and the casing 12. The inlet connection 11 is tangentially installed in the horizontal plane in the upper parts of the casing 12. Opposite the inlet piece Cera 11 is tangentially installed inlet pipe 13. An additional deflector 14 is installed in the cavity between housing 1 and casing 12. Ultrasound emitters 4 are installed on the inner surface of casing 12.

The device works as follows.

Water under pressure through the inlet pipe 13 enters the cavity between the housing 1 and the casing 12, where an additional deflector is installed 14. The additional deflector 14 gives the water a rotational motion around the housing 1, increasing the time the water stays in the cavity between the housing 1 and the casing 12. Here the water is disinfected with the help of ultrasonic waves generated by ultrasound emitters 4 located on the inner surface of the casing 12, which cause a cavitation effect, which contributes to the destruction of water polluting chemicals and microorganisms. At the same time, ozone is supplied through the inlet 11, which is installed tangentially in the horizontal plane in the upper part of the casing 12 opposite the inlet 13. When ozone enters the water, it oxidizes the dissolved ferrous iron in the water to water-insoluble ferric iron, and the manganese ions in the water form insoluble manganese dioxide. Ozone also disinfects, discolors and deodorizes water. Then the water through the perforated tube 7 and enters the inner cavity of the housing 1, where, with the help of the deflector 8, it is drawn into rotational motion along a logarithmic spiral from the center of the deflector 8 to its periphery. When the water rotates in the deflector 8, the particles of contaminants in the liquid are thrown under the action of centrifugal force to the surfaces of the deflector 8, and, then, to the walls of the housing 1 and fall into the sump 5. After the end of the spiral movement in the deflector 8, the water changes its direction of movement, loses its speed and passes through the filter element 10, where it is additionally cleaned of impurities and insoluble iron and manganese compounds contained in it. Then the water, purified from impurities, enters the space between the upper part of the filter element 10 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 light-emitting diodes installed on the inner surface of the lid makes it possible to more effectively disinfect water, since the quality of ultraviolet treatment improves with an increase in the purity of the water, and already purified water is processed in the upper part of the device body. After that, the water is removed to the outside of the device through the outlet 6 installed in the cover 2. The impurities in the water accumulate in the sump 5 and in the filter element 10. Periodically, the cover 2 is removed, the filter element 10 is replaced and the dirt accumulated from the lower part of the housing 1 is removed.

Installation of a sealed casing outside the casing that repeats the shape of the casing, installing an additional deflector between the casing and the casing, installing the lower end of the perforated tube in the cavity between the casing and the casing, supplying the casing in the upper part with an inlet pipe tangentially located in the horizontal plane and installed tangentially in the horizontal plane in the upper parts of the casing opposite the inlet pipe with the inlet fitting, as well as the installation of ultrasound emitters on the inner surface of the casing, allows to ensure high-quality purification of water from impurities and soluble iron and manganese compounds contained in it and at the same time to disinfect it.
