    A unique and novel mixing device to effect an intense and rapid mixing of two fluids which is comprised of a venturi tube (47) connected to the first fluid and a feed member (48) disposed around the venturi tube (47) through which the second fluid can flow. The feed member (48) has one or more channels (49) which connect with the venturi tube through which the second fluid can be admixed with the first fluid. A baffle (54) is positioned axially opposite the exit of the venturi tube (47) to promote additional mixing.

    This invention relates to devices for mixing two media.
    A device for mixing two media is known, comprising a housing made in the form of a Venturi tube with inlet and outlet nozzles and channels for supplying the second medium Cl
    However, this device does not provide sufficient process intensity.
    The closest to the proposed technical essence and the achieved result is a device for mixing, comprising a housing with outlets, a Venturi tube installed in the housing with supply channels made in its neck, a mixing chamber located under the Venturi tube, and a reflector fixed on the housing coaxially with the Venturi C2D pipe,
    However, the known device does not provide sufficient stirring intensity, which makes it impossible to use it for interaction with highly reactive media, in which side reactions may occur.
    The purpose of the invention is to intensify the process.
    The goal is achieved by the fact that a device for mixing two media, containing a housing with eaves branch pipes, a Benturi tube with supply channels installed in its neck, a mixing chamber located under the Venturi tube, and a reflector mounted on the Venturi tube coaxially , snabzhi: o turbulent chamber located between the Venturi tube and the mixing chamber and made with a conically expanding outlet, and the reflector has a concave shape with concavity directed toward the Vendou pipe ri
    The device is equipped with blades attached to the housing coaxially to the reflector.
     In the proposed mixing device, the film of the second liquid, which can form on the walls of the relatively short second part of the Venturi pipe, is detached from the wall during a sharp transition from the Venturi pipe to the turbulent chamber, strong turbulence in this place is provided. Feeds rapid and intensive mixing. The outer part of the liquid jet entering the second chamber from the turbulent chamber is approximately conical and strikes at an angle of approximately 90 with a second liquid jet of conical shape, the angle of which at the apex coincides with the concave plate, on which the central part of the liquid jet falls. turbulent chamber. 1 Akim surround; ; ,,, "liquids are subjected to three steel and mixing, the first mixing in the venturi; the second mixing in a turbulent chamber and the third sewing in the secondary mixing chamber.
    As a result, intensive and rapid mixing is achieved.

    0 combined bolt 16, zone 17 between the mouth 18 of the turbulent chamber 1 and the plate 15 (this space forms a secondary mixing chamber, its length is O, 2-2 3), transverse drilling 19 in the housing 1, which
    connects eccentric drilling 6 to an annular chamber 9, guiding blades 20, which transmit rotational motion of a mixed fluid exiting the secondary mixing chamber, a ring 21 on which blades 20 are attached, for example, csapKof, a cross 22 of rectangular strips reinforced (for example, welding in a ring 21, in the center of which a plate 15 is attached, a nut 23 screwed onto a bolt 16, the plate of which 15 is attached, bolts 24, a ring 21 with blades 20 with a casing 1, bolts 25, is fastened with which the liner 2 is mounted in the housing, and the seal ring guides 26-28
    FIG. loL is the angle between the internal profile of the section ± Venturi tube 7 and the profile of the connecting part of the turbulent chamber 11; this angle in this example is P the angle between the tangent to the concavity profile of the plate 15 in the point where it has the largest diameter, and. by extending the profile of the conically expanding part of the turbulent chamber 11, this angle is about 90 °.,
    The device works as follows.
    Through line 3, water is fed at a speed of 60 m / h, and through line 4 a nearly saturated solution of potassium permanganate is fed at a speed of 1.8. Under these conditions, the residence time of the liquids in the mixer is about 0.01 s.
    In a series of joints between the blades 20 around the periphery of the mixer at different levels, samples are simultaneously taken several times using samplers. A colorimetric analysis shows that there is no difference within the limits of measurement error between individual samples, which means that the proposed mixing device provides perfect mixing in a very short time of about 0.01 s.
    The dimensions of the device must be within the following limits: the length of the first part — Venturi tube (from the inlet to the mount) is 0.4–11) V is the length of its second part (from the throat to the outlet) 0.2-0.5L, the length of the turbulent chamber is no more than 1, 53); the concavity diameter of the concave plate is 0.6–3D5; the length of the secondary mixing chamber (the bottom of the concave plate is 0.2–20; the angle between the internal profile of the turbulent section and the profile of the Venturi tube where the turbulent chamber is connected to the Venturi tube 90–135 g

    Internal profile of the pipe section
    0 Venturi has a smooth convex shape, which limits the pressure loss in the tube to the lowest possible. The periphery of the secondary mixing chamber is provided with a ring of blades that create a rotational movement of the outflowing fluid in the collecting vessel. The collecting vessel may be cylindrical and in this case it is recommended to provide at least
    At least one tangentially discharged discharge pipe. Part of the energy of fluid movement is thus utilized. However, collecting vessels of a non-cylindrical shape are not excluded J, for example, collecting
