The disadvantage of the closest analogue is increased hydraulic loads, low efficiency and limited functionality of the apparatus for mixing aqueous solutions.

The basis of the useful model is the task of improving the apparatus for mixing aqueous solutions by making a coaxial circulation nozzle, which allows to reduce hydraulic loads, increase the efficiency of mixing the aqueous solution, and expand the functionality of the apparatus for mixing aqueous solutions and reagents.

The set task is solved by the fact that in the apparatus-mixer of aqueous solutions and reagents, which contains the body, radial perforated pipelines for the removal of the mixture, circulation

From the nozzles, the reagent supply nozzle, the reagent outlet hole, the reagent mixing chamber and the tangential supply pipelines of the reagents, the conical seal of the floating sludge, according to the useful model, the circulation nozzle is made of two/three coaxial pipes.

In examples of a specific implementation, the circulation nozzle is made of three coaxial pipes.

The execution of the circulation pipe in the apparatus-mixer of aqueous solutions and reagents from two/three coaxial pipes reduces hydraulic loads, increases the efficiency and extends the functional capabilities of the apparatus-mixer of aqueous solutions and reagents for mixing the relevant components and ingredients in aqueous solutions.

The essence of the useful model is explained by the drawings, where in Fig. 1 shows the construction diagram of the apparatus-mixer of aqueous solutions and reagents; in Fig. 2 - circulation nozzle of the apparatus-mixer of aqueous solutions and reagents with three coaxial pipes (section at the level of 1/3 of the height of the circulation nozzle); in Fig. C - the circulation pipe of the apparatus-mixer of aqueous solutions and reagents with two coaxial pipes (section).

The proposed design of the apparatus-mixer of aqueous solutions and reagents includes a body 1, radial perforated mixture removal pipes 2, a circulation nozzle 3 made of coaxial pipes 9, a reagent supply nozzle 4, a reagent outlet hole 5, a reagent mixing chamber b and tangential supply pipelines of reagents 7, cone sealer 8 of sludge.

In the drawings for the apparatus-mixer of aqueous solutions and reagents, the following designations are used: p: - the inner diameter of the circulation pipe 3; p»: - the average diameter of the circulation pipe 3;

Oz - the outer diameter of the circulation nozzle 3;

No: - working height of the circulation nozzle 3;

No - the height of the circulation nozzle Z above the location of the radial perforated pipelines for the discharge of the mixture 2.

The apparatus-mixer of aqueous solutions and reagents works as follows.

The treated water enters the lower part of the housing 1, then to the circulation nozzle 3, where it is first mixed with the reagents supplied from the upper part of the housing 1 of the mixing device. At the same time, the solution of the mixture fills the radial perforated pipelines for the removal of this working solution. At the point of connection of the perforated pipelines (cut at an angle of 457) to the housing 1, the speed of the solution flow increases, which contributes to the appearance of additional vortices when mixing the solution.

From the bottom, a reagent supply nozzle 4 is connected to the reagent mixing chamber 6, with a double reagent mixing nozzle 9. The holes for the reagent outlet 5 contribute to the intensification of the mixing of the reagent components with the aqueous solution, and, subsequently, with waste water and other similar technical liquids, which has a positive effect on the energy and ecological and economic indicators of the apparatus-mixer of aqueous solutions and reagents.

The construction of the circulation nozzle C from two/three coaxial pipes creates conditions for more intensive mixing of the components of the aqueous solution, increasing the dissolution of the components of the reagents, and expanding the functional capabilities of the device. At the same time, the separate introduction of streams of the working solution contributes to its effective mixing, ensuring the homogeneity of the aqueous solution when using reagents, and creating conditions for the homogeneity of the flow in the range of working supplies of the equipment.

Thus, the developed apparatus-mixer of aqueous solutions and reagents with coaxial pipes of the circulation nozzle increases the power of water purification equipment, expands the possibilities of using various types of reagents and ensures the efficiency of wastewater treatment of industrial enterprises.
