Dereza - Application No. ts201708377; statement 14.08.2017, publ. 10.01.2018, Bul. Mo 1), which contains the apparatus body, radial perforated pipelines for removing the mixture, a circulation nozzle, a reagent supply nozzle, a reagent outlet hole, a reagent mixing chamber and reagent tangential supply pipelines, a cone sealer for float sludge.

The disadvantage of the closest analogue is the low degree of mixing of reagents with wastewater, hydraulic resistance that occurs when the flow of an aqueous solution is introduced, and increased hydraulic loads in the operation of treatment facilities.

The useful model is based on the following task: to improve the apparatus-mixer of aqueous solutions by changing the design of the reagent supply nozzle, which is made of coaxially arranged pipes one inside the other, to ensure the efficiency of mixing aqueous solutions and reagents, to increase the efficiency of work and to expand the functionality of the water purification equipment.

The task is solved by the fact that in the apparatus-mixer of aqueous solutions containing

Z body, radial perforated pipelines of the mixture removal, circulation nozzle, reagent supply nozzle, reagent outlet hole, reagent mixing chamber and tangential supply pipelines of reagents, conical slurry float sealer, according to a useful model, the reagent supply nozzle is made of coaxially arranged pipes .

The execution of the reagent supply nozzle from coaxial pipes creates conditions for the appearance of smaller fractions of impurities in wastewater in the water-air mixture, increases efficiency, ensures the stability of the mixer of water purification equipment and expands the functionality of water purification equipment.

The essence of the useful model is explained by the drawings, where in fig. 1 presents the structural and technological scheme of the mixing device; in fig. 2 - live cross-section of nozzle 4 of reagent supply with coaxial pipes.

The proposed design of the mixing device includes the body 1 of the device, the radial perforated pipes 2 of the mixture outlet, the circulation nozzle 3, the reagent supply nozzle 4, the holes 5 for the exit of the reagent into the lower part of the body 1 of the device, the chamber 6 for mixing the reagent and the pipelines 7 for the tangential supply of reagents, a conical sealer 8 of floating sludge from coaxial pipes 9, located one inside the other.

The apparatus-mixer of aqueous solutions works as follows.

The treated water enters the lower part of the housing 1 of the apparatus, then rises to the level of the radial pipes 2 with bevels and the circulation nozzle 3, where it is initially mixed with reagents supplied by a downward flow from the upper part of the housing 1 of the mixing apparatus, through the nozzle 4 reagent supplies with coaxial pipes 9, located one inside the other.

In nozzle 4 of the reagent supply, made of coaxial pipes, there is a movement of ascending and descending flows, which contributes to the intensification during mixing of the aqueous solution, creates conditions for the formation of homogeneity of the water-air mixture and stabilization of the wastewater treatment process.

The water flow fills the radial perforated pipelines for the removal of the solution, along which the flow moves in different directions with the mixture, saturating them with oxygen, as a result of which the mixing becomes more efficient and saturated. At the point of connection of the perforated pipelines to the housing 1 of the mixing device, the flow rate increases, which contributes to the appearance of additional vortices when mixing the solution, the formation of uneven movement of the water flow, which creates favorable conditions for the movement of the water flow with the reagent solution.

Perforated pipelines 7 cut at an angle create conditions for the appearance of additional flow vortices, which allows for more complete dissolution and promotion of effective mixing of the reagent components in the aqueous solution.

The structural and technological test parameters of the apparatus for mixing aqueous solutions with the nozzle 4 for supplying the reagent, made of coaxial pipes 9, located one inside the other, are given in the table.
