The invention refers to the centrifugal atomizers used in chemical and other industries for the processes associated with the processing suspensions, solutions and emulsions.
Known centrifugal atomizer fluid by A.S. The USSR №154177, F26B 3/12, 1961, which are rapidly rotating disc and cylinder with internal channels of different forms (prototype).
The disadvantage of this sprayer is that obtaining fine-dispersed Rasulov (drops of diameter 50...200 microns) through nozzles connected with significant energy consumption (15 kW per 1 ton of liquid) and the need to use complex and expensive drive mechanisms, as it has a big drag caused by the separation of the boundary layer and vortex formation at the flow around cylindrical nozzle inserts. Other significant shortcomings nozzle of the spray are highly polydispersity received spray and small wetted perimeter of channels.
Effect : increased efficiency spray and the reduction of energy consumption.
This is achieved by the fact that in the spray disk containing the case with the inner chamber in which fixed nozzles, each of nozzles contains the frame, which is made in the form of the inlet fitting with a Central hole, and rigidly joined with it and coaxial cylindrical shell with internal thread and expansion chamber, coaxially to the case, while coaxial the body in its lower part is connected to the core via thread nozzle, made in the form of the inverted glass in the bottom of which is made turbulent swirl flow with at least two inclined to the nozzle axis inputs in the form of cylindrical holes located at the end the surface of the nozzle, which also made the Central cylindrical throttling hole, United with mixing chamber nozzle, consistently connected with diffuser output of the camera.
Figure 1 shows a General view of the proposed spray, figure 2 - scheme of the nozzle.
Spray disc (figure 1) has a hollow body 1 with cover 2 with the Central hole 3 for the fluid. Building 1 is rigidly connected with the shaft 4, whose axis is perpendicular to the axis connecting at least three radial nozzle 5, which are fixed on the side of the case 1.
Each of 5 nozzles (figure 2) contains building 6, which is made in the form of the inlet fitting with a Central hole 8, and rigidly joined with it and coaxial cylindrical core 7 with internal thread 10. In a cylindrical shell is located 5 expansion chamber 9, coaxial body. This coaxial the body in its lower part is connected to the socket 7 by a thread 10 nozzle 11, made in the form of the inverted glass in the bottom of the 12 which made turbulent swirl flow with at least two inclined to the nozzle axis inputs in the form of cylindrical holes 14 and 15, located in the end surface of the nozzle 11, formed his bottom 12. In the end surface of the nozzle 11 also made the Central cylindrical throttling hole 13, coupled with mixing chamber 16 nozzle, consistently connected with diffuser output camera 17. Moreover, the effective area of flow sections sloped cylindrical holes 14 and 15, together, and the center hole 13 equal.
Spray disk works as follows.
The working fluid through the Central hole 3 cap 2 is fed into the inner cavity of the body 1, which is distributed under the action of centrifugal force circular layer on the lateral surface, evenly creating pressure in all radial 5 nozzles. At rotation of liquid ring creating pressure, by which liquid overcome local resistance input and enters into the inner cavity of 5 nozzles.
The spray comes in building 6 through the Central hole 8, then into the expansion chamber 9, coaxial housing 6. After camera 10 fluid is directed to the nozzle 11, which is distributed in several directions: the first - on the Central cylindrical throttle opening 13 in the mixing chamber of 16, and the second in the turbulent swirl flow with oblique to the nozzle axis inputs in the form of cylindrical holes 14 and 15, also connected to the mixing chamber 16 nozzle, where the interaction of these common thread is their split with the formation of a turbulent flow heading to the diffuser outlet chamber of 17, where additional crushing of liquid drops in their collision with each other due to the expanding of turbulent fluid flow.
The use of the spray in comparison with the known allows approximately 1.5 times to reduce the frequency of rotation of the shaft 4 of the drive mechanism of the housing 1 and simplification of its design to improve reliability, not less than 2 times to reduce the specific energy consumption for sputtering liquids.
Spray disk that contains the cover, which establishes the nozzle with each nozzle contains a body with a camera turbulence, characterized in that the body is made in the form of the inlet fitting with a Central hole and rigidly connected with it and coaxially cylindrical casing with internal thread and expansion chamber, coaxially to the case, while coaxially to the case in its lower part is connected to the core via thread nozzle, made in the form of the inverted glass in the bottom of which is made turbulent swirl flow with at least two inclined to the nozzle axis inputs in the form of cylindrical holes located at the end surface of the nozzle, which also made the Central cylindrical throttling hole, United with mixing chamber nozzle, consistently connected with diffuser output of the camera.
