Description

The invention relates to centrifugal nebulizers used in chemical and other industries for processes associated with the processing of suspensions, solutions and emulsions.

Known centrifugal atomizer fluid A. USSR No. 154177, F26B 3/12, 1961, which is a rapidly rotating disk and cylinder with internal channels of various shapes (prototype).

The disadvantage of this sprayer is that the production of finely dispersed sprays (droplets with a diameter of 50 ... 200 microns) through such sprays is associated with significant energy consumption (about 15 kW per 1 ton of liquid) and the need to use complex and expensive drive mechanisms, since it has a large drag due to separation of the boundary layer and vortex formation during flow around cylindrical nozzle inserts. Other significant disadvantages of the nozzle atomizer are a high degree of polydispersity of the resulting spray and a small wetted channel perimeter.

The technical result is an increase in spray efficiency and a reduction in energy consumption.

This is achieved by the fact that in a disk atomizer containing a housing with an internal chamber in which the nozzles are fixed, each of them contains a housing with a nozzle placed in it, which is made in the form of an inverted cup, in the bottom of which there is a turbulent swirl of fluid flow, at least two inputs inclined to the nozzle axis in the form of cylindrical holes located in the nozzle bottom, where a central cylindrical throttle hole is also connected to the nozzle mixing chamber, subsequently connected to the diffuser outlet chamber, and at the bottom of each nozzle, to the end surface of the cylindrical sleeve, a divider made in the form of a perforated disk, the convex part of which is directed towards the diffuser outlet chamber, is attached by means of at least three spokes. In FIG. 1 shows a General view of the proposed atomizer, FIG. 2 is a nozzle diagram.

The disk atomizer (Fig. 1) has a hollow body 1 with a cover 2 having a central opening 3 for supplying liquid. The housing 1 is rigidly connected to the shaft 4, the axis of which is perpendicular to the axis connecting at least three radial nozzles 5, which are mounted on the side surface of the housing 1.

Each of the nozzles 5 (Fig. 2) contains a housing 6, which is made in the form of a supply fitting with a central hole 13, and rigidly connected to it and a coaxial cylindrical sleeve 12 with an internal thread 10. In the cylindrical sleeve 12 there is an expansion chamber 9, coaxial to the housing 6. In this case, coaxially to the casing, in its lower part it is connected to the sleeve 12, by means of a thread 10, a nozzle 11 made in the form of an inverted cup, in the bottom 7 of which a turbulent swirl of a fluid flow is made with at least two inclined to the axis of the nozzle in the form of cylindrical holes 14 and 15 located in the bottom 7 of the nozzle 11, in which the central cylindrical throttle hole 8 is made axisymmetrically to the housing 6, connected to the mixing chamber 16 of the nozzle 11, connected in series with the diffuser outlet chamber 17. Moreover, the effective pass-through areas of inclined cylindrical holes 14 and 15, taken together, and the Central hole 13 are equal to each other.

In the lower part of each of the nozzles 5, to the end surface of the cylindrical sleeve 12, a divider 19 is attached via at least three spokes 18, made in the form of a perforated (not shown) disk, the convex part of which is directed towards the diffuser outlet chamber 17 .

The spray disk works as follows.

The working fluid through the Central hole 3 in the cover 2 is fed into the inner cavity of the housing 1, where it is distributed under the action of centrifugal force by an annular layer along its lateral surface, uniformly creating pressure in all radial nozzles 5. When the fluid ring rotates, pressure is created, due to which the liquid overcomes local input resistance and enters the internal cavity of the nozzles 5.

The sprayed liquid enters the casing 6 through the central opening 13, then into the expansion chamber 9, coaxial to the casing 6. After the chamber 9, the liquid is directed to the nozzle 11, where it is distributed in several directions: the first through the central cylindrical throttle opening 8 into the mixing chamber 16, and the second - into a turbulent swirl of a fluid flow with inlets inclined to the nozzle axis in the form of cylindrical holes 14 and 15, also connected to the mixing chamber 16 of the nozzle, where during the interaction of these flows occurs um their crushing with the formation of a turbulent flow directed to the diffuser outlet chamber 17, where the crushing of liquid droplets occurs when they collide with each other due to the expanding turbulent fluid flow. The divider 19, made in the form of a perforated disk, the convex part of which is directed towards the diffuser outlet chamber 17, additionally crushes the fluid stream, turning it into a fine stream.

The use of the proposed sprayer in comparison with the known ones allows to reduce the rotational speed of the shaft 4 of the drive mechanism of the housing 1 by approximately 1.5 times and thereby simplify its design and increase reliability, as well as reduce specific energy consumption for spraying liquid by at least 2 times.
