If necessary blades 2 come back in initial position due to elasticity of a material of blades. After adjustment andachievements of the greatest efficiency of clearing clowns 7 are fixed in this position by means of spring washers and counter nuts. Blades vortex generator bundling on a sine wave curve that promotes decrease reduction in hydraulic resistance of the device. 

Increase of efficiency dust separation is caused by installation in the device of the axial sprinkler punched by apertures of small diameter, placed on a screw line. Apertures are executed in such a manner that the jet of a liquid from them is directed tangential to a surface of an axial sprinkler. The comer of an inclination of a jet is provided with directing plugs, compaction in apertures of an axial sprinkler. Thus due to impact following under a pressure the spiral film-drop liquid veil is formed of apertures of an axial sprinkler of liquid jets with a peripheral edge of blades vortex generator. 

Blades vortex generator, executed in the form of screw, are established installed on all length separation zones of the device that enables to support maintain intensity twist a constant on length separation zones at Pj = or to change it her under in advance chosen law at P,t P. ... 

At rotation of a rotor 12, liquid takes a great interest in blades vortex generator 5, moistens their surface and is sprayed in the form of fine drops on a way of movement of cleared gases that provides high-intensity contact of phases outside of conic vortex generator 5 and raises increases efficiency of clearing of gas. 

In Germany, the DLR Institute of Aerodynamics and Flow Technology has been involved in research on the impact of tubercles on the performance of helicopter blades. In fact, the research has already resulted in a patent on Leading-Edge Vortex Generators, and the invention has been used to design and build various experimental helicopter blades, which are undergoing tests. If all the results of these tests are positive, as it is expected, a...

For a supply of a liquid in a zone of contact, it is offered to use hollow blades axial, conic, or tangential vortex generator [12002D19]. But, they are complex difficult in manufacturing and reduce relative section vortex generator that limits area of their application. Diameter and height of contact branch pipes essentially influence metal consumption of the device and efficiency mass transfer. For an intensification mass transfer in a number of designs (wed), it is offered to put render on a surface... 

At twist, a stream by means of axial vortex generator with flat or profiles blades hydraulic resistance, depends only on average speed of gas in cracks between blades and their forms. Hydraulic resistance vortex generator with flat blades in 1.5 times above, than with profiles that speaks reduction of losses an input entrance in the device and various conditions of movement of a stream between plates (Kutepov, 1977). 

At a turbulent mode of current. Re < 5.5 T 0 for vortex generator with flat blades dependence is offered. 

For vortex generator with spiral blades, the numerical factor in this formula is replaced on 12.7. 

The Comer of installation of blades on an input entrance in vortex generator shows on hydraulic resistance drip pan only at values P < 50°, which should be accepted as optimum (Mielazarek, 1978).
