Scrubber (figure 1 and 2) includes a housing including a tapered 1, the cylindrical part 2 and the sludge trap 3, the pipe 4 to enter the dusty gas pipe 5 with the chamber 6 to exit purified gas spiral straightener 7 thread. Irrigation device made in the form of at least two outer pipes 11 and 12, associated with the common inlet 13 of the liquid, each of which is embedded in the housing 1 of the bottom 10 and the top 8 and nozzle 9 having the opposite direction of the twist of the sprayed fluid from the irrigation device. The upper nozzle 8 and 9 and the bottom 10 (on the pipeline 12, the nozzle is not shown) irrigation device made in the form of a hollow, closed at one side, a cylindrical chamber (not shown)having a tangential longitudinal groove for exit of fluid. In the lower part of the body is placed the sludge trap 14 with l-shaped plate 15.

Coaxially to the housing 16, in its lower part connected by a sleeve 19 with the internal thread of the nozzle 20, is made in the form of a centrifugal swirl 21 of fluid flow in the form of a hollow cylindrical insert 27 with at least three tangential inlets 28 in the form of cylindrical holes (figure 3). The sleeve 19 is part of the nozzle 20 and is installed coaxially aligned and coaxially with respect to the centrifugal swirl 21.

In the end surface of the centrifugal swirl 21 executed serially connected coaxially between itself and the housing 16 axial conical 25 26 and cylindrical throttle openings.

Centrifugal swirl 21 is mounted in the cylindrical chamber 24 of the casing with the formation of an annular cylindrical chamber 22 for supplying a fluid to the tangential inlets 28 of the centrifugal swirl 21 and is connected with three cameras installed in series and coaxially him: conical 29, 30 cylindrical, cone output by the camera 31, and the camera is set so that the output of one camera is input to the other. Tangential inlets 28 in the form of channels, tangentially situated to the inner surface of the insert 27.

Centrifugal vortex nozzle operates as follows.

In the cavity of the insert 27, which performs the function of a centrifugal swirl 21 of the liquid, going on the t formation of the vortex, which twists the stream of liquid flowing from the cylindrical 26 throttle openings.

Swirling fluid flow in the cavity of the insert 27 is formed by mixing of the jets emanating from the tangentially directed channels 28.

At the outlet from the cavity of the insert 27 is formed in the fluid flow, characterized by a constant tangential velocity. Thus the angular velocity of the swirling fluid flow in the channel of the nozzle 20 of the dispenser defines the angle of the spray pattern generated by the gas-droplet stream.

The magnitude of the tangential velocity in the cavity of the insert 27 depends on the ratio of the total cross-sectional area of the tangential channels 28 and the sectional area of the axial cylindrical 26 throttle openings. Formed in a centrifugal swirl 21 swirling fluid stream flows into the inlet of the conical chamber 29. With the passage of sections 29 and 30 is formed accelerated fluid flow. Rapid formation of cavitation bubbles in the swirling fluid flow occurs in the diffuser outlet chamber 31.

The scrubber operates as follows.

Dust-Laden gas stream enters the housing 1 through a tangential entry 4 dusty gas stream, and meets in its path twisted atomized liquid stream having a direction of twist, as the opposite is UPRAVLENIE twist the gas stream, and passing. As a result of this interaction forms a gas-liquid suspension which passes through the straightener 7 in the pipe 5 and discharged into the atmosphere. The extraction of the sludge through the sludge trap 14.

The proposed apparatus can be used for removal of fine dust and air humidification in air handling units and air conditioning installations. The effectiveness of the proposed design of the apparatus increases due to the application of a counter-swirling flows of liquid and gas, and is in the above processes and the capture of dust particles larger than 5 microns to about 95%...97%.
