Description

The utility model relates to the field of processing liquid media, in particular, water and aqueous solutions, juices, etc. for the purpose of their disinfection, it can also be used to obtain drinking water, as well as to obtain water suitable for discharge into surface water intakes.

Known devices for disinfecting water and aqueous solutions using ultraviolet radiation (RF patent 2019529 C02F 9/00, C02F 1/32). The principle of operation of UV devices is based on the use of hard ultraviolet radiation from a UV lamp, which, when exposed to microbial cells, destroys protein colloids and their protoplasm enzymes. The device consists of a housing made of stainless steel, with two nozzles for the exit and entry of water. Inside the case there is a quartz protective bulb where the UV lamp is placed. The device is equipped with a power supply. Light and sound alarms warns of the need to clean the quartz flask from plaque or replace the UV lamp.

Known devices for disinfecting water and aqueous solutions with ozone. (RU 2118297 C02F 1/78, B01F 3/04; RU 2210534 C1 7 C01B 13/11). They are based on the ability of ozone to disinfect and sterilize water through the oxidation and destruction of proteins of bacteria and viruses. Virtually unknown microorganisms, bacteria, spores and viruses resistant to ozone. The devices consist of an oxygen concentrator, an ozone generator, including a housing with dielectric partitions, high voltage electrodes (9-12 kilovolts) and a reaction chamber for mixing the water-gas mixture with a gas stream dispersant.

The disadvantages of the devices include the high energy intensity of the ozone production process and the presence of high voltage elements in the system, which impairs the safety of the operational parameters of ozonation plants.

Known devices for the disinfection of aqueous media by the method of photolytic ozonation in which ozone is processed in a stream of ultraviolet radiation (RU 2109690 C1 C02F 1/32, C02F 1/78, C01B 13/11), The devices include an ozone generation unit with high voltage electrodes, a reaction a mixing chamber with inlet and outlet nozzles for supplying and discharging the treated water, a water-gas-ozone stream dispersant, and an ultraviolet lamp located in a case made of a material transparent to ultraviolet radiation

The disadvantages of the device include high energy intensity and increased danger and complexity of the operational parameters of the equipment.

The technical result, the solution of which is claimed by the claimed utility model, is to create a simple structurally and in operation device for disinfecting water with low energy consumption and safe operating parameters.

The technical result in the claimed utility model is achieved due to the electrochemical generation of oxygen in the treated water stream passing through the ultraviolet radiation zone. The effect is based on the ability of oxygen to recombine into ozone atoms under the influence of ultraviolet radiation.

Installation for water disinfection consisting of a body, with two nozzles for water inlet and outlet, a protective bulb, where the UV lamp is placed, differs in that insoluble working electrodes are placed above the inlet pipe, connected through an additional outlet fitting to a low-voltage direct current source and a block management.

An ultrasonic oscillator can be additionally placed between the inlet pipe and the working electrodes.

A schematic representation of the inventive installation is shown in figure 1., where 1 is the housing, 1 ¹ is the cover, inlet pipe is 2, output pipe is 3, protective bulb 4, UV lamp is 5, working electrodes are 6, power supply nipple is 7 , UV lamp power source - 8, electrode power source - 9, insulating gaskets - 10.

Installation works as follows.

The treated water through the inlet pipe (2) enters the disinfection unit case (1), flows around the protective flask (4) with a UV lamp (5) located inside it, and leaves the outlet pipe (3). Directly above the inlet pipe (2), working electrodes (6) are installed in the device, made, for example, of materials: copper cathode, ruthenium oxide-coated titanium anode (ORTA), to which power is supplied from the connection (7) DC source with a supply voltage not lower than the discharge voltage of water.

The working electrodes (6) are supplied with power from a direct current source, for example, 2, 8 V.

Under the influence of an electric current at the anode, the release of finely dispersed oxygen bubbles begins. The resulting stream of gas-water mixture flows around the protective flask (4). When the mixture passes through a stream of ultraviolet radiation from a UV lamp, the oxygen generated at the anode recombines into ozone, which, together with ultraviolet radiation, disinfects the treated stream.

The device is equipped with an automated control system. Light and sound alarms warns of depressurization of the system, the need to clean the surface of the protective bulb from deposits or replace the UV lamp.

A check showed that the effect of disinfection (sterilization) of water in the proposed installation is achieved much faster than when using UV radiation.

* Use as part of a utility model of an ultrasonic emitter located between the water inlet and the working electrodes

The increase in the speed of the disinfection process can be explained by the fact that the dispersion of the gas phase in the ultrasonic field increases and pollution of the insulating housing in which the UV lamp is installed is prevented.

The proposed utility model can significantly reduce the energy consumption of the disinfection process, to exclude elements using a high operating voltage from the disinfection system, which increases the safety of operational operations and ensures low energy consumption when using a direct current source.
