A device for disinfecting water is known, comprising a housing, water supply and drainage units, sources of ultraviolet radiation with protective covers made of a material transparent to ultraviolet rays, ultrasonic emitters located on the outer side of the housing at the nodal points of maximum vibration intensity and in contact with it, while contact diameter is less than half wavelength.

RU No. 2005113252, IPC C02F 1/36, 2006.

The disadvantages of the known device for disinfecting water are the low productivity of the process and the uneven degree of disinfection throughout the volume of the stream.

The tasks to which the proposed solution is directed are to increase the productivity and efficiency of disinfecting water in the stream.

The technical result is achieved by the fact that the device for non-reagent disinfection of liquids comprises a housing with water supply and drainage units, sources of ultraviolet radiation with protective covers made of a material transparent to ultraviolet rays, ultrasonic emitters, while the device further comprises an insert located in the body in the form of an extended body, on the inside of which there are ultrasonic emitters in the nodes of maximum intensity of oscillations, and on the outside of the body ultrasonic emitters are located at the nodes of maximum intensity of oscillations and are tuned to a synchronous or different resonant frequency with ultrasonic emitters located on the inner sides of the insert or several inserts, and a flow swirl is installed in front of the flow inlet into the housing.

The drawings show a device for reagentless disinfection of liquids:

- figure 1 is a General view;

- figure 2 is the same in section;

- figure 3 is a device element with ultrasonic emitters on the housing and on the sides of the insert;

- figure 4 is an element of the device with a swirl.

The device for reagentless liquid disinfection contains a housing 1, on the external side of which there are ultrasonic emitters 2, inside the housing 1 there are sources of ultraviolet radiation 3 with protective covers transparent to ultraviolet rays, and located around the insert 4, on the inside of which there are also ultrasonic emitters 5 In this case, the ultrasonic emitters 2 and ultrasonic emitters 5 are located at the nodal points of the maximum vibration intensity and are configured for synchronous or decomposition the resonant frequency of oscillations relative to each other. Before the flow inlet into the housing 1, a swirler 6 of the flow is installed. In the course of the flow, several inserts can be installed, similar to insert 6 and tuned to different resonant frequencies.

The principle of operation of the device for reagentless disinfection of the liquid is as follows. The fluid flow enters the housing 1, where under the action of ultraviolet radiation from sources of ultraviolet radiation 3 and cavitation processes formed under the action of ultrasonic emitters 2 installed on the outside of the housing 1 and ultrasonic emitters 5 located on the inner sides of the insert 4, some types of dissolved salts contained in liquids that are released and precipitate. At the same time, also under the influence of these factors, an effective disinfection of water occurs; pathogenic microflora dies under the action of high-intensity cavitation processes formed in the wall regions of the housing 1 and insert 4. In addition, a positive effect is observed: self-cleaning of UV protective covers that are transparent to ultraviolet radiation (not shown in the drawing).

The design of the housing of the ultrasonic emitters 5 in the cavity of the insert 4 significantly reduces noise during operation and meets the highest sanitary and hygienic conditions for personnel. Swirler 6 contributes to a more uniform degree of processing fluid flow throughout the volume.
