The famous "Vortex tube Century. And. Medenine" (prototype) [1].

In the vortex tube, the compressed gas is fed into mehoopany enter, where it expands, and gets a spin. Further, the swirling flow enters the conical vortex chamber energiesparende, where the process of energy split the gas with the formation of two streams, one of which is moving on the periphery and having a higher temperature and pressure, out through the vaned diffuser (precirculated part) in the circular pipe and then to the ejector. Another peripheral portion of the vortex flow (recircula part) enters the annular gap at the periphery of the aerodynamic body to allow the grid and then to the heat exchanger - regenerator with ribbed inner and outer heat transfer surfaces. Spinning, he washes the inner fin heat exchange surface and through the spool valve and the transport zone enters the Central part of this model allow lattice. Passing lattice with cylindrical nozzles gas is split into smaller streams and vigorously blown up in pricebuy cavity camera energiesparende. In order to streamline the flow Klan with the possibility of axial movement and adjustment of the flow optimum amount of the recirculating gas.

Cooled in the heat exchanger-regenerator gas moves in the axial region of the camera energiesparende from this model to allow the lattice to the diaphragm and, optionally achladies goes through the hole in the diaphragm in the axial and slot diffusers and forth to the consumer.

As an active gas ejector is peripheral hot stream coming out of the shoulder of the cone (precirculated part of the hot stream). Passive flow ejector (cooling medium heat exchanger-regenerator) is atmospheric air, passively through the heat exchanger-regenerator ejector working on precirculated part of the hot flow vortex tube.

In the considered vortex tube underutilized potential energy of cold gas stream and potential energy re-circulating hot air stream and therefore it needs to be constructive and technological changes and additions.

The aim of the invention is the expansion of the field of rational use of vortex tubes by partial conversion of potential energy of cold and recirculating hot gas flows in the energy of sound and ultrasonic vibrations, Stausee vortices throughout the volume of energiesparende and thus increase the efficiency of the process energiesparende gas, and therefore, the efficiency of the vortex tube, as well as the efficiency of the pipe by utilizing the heat of the cold stream in the heat exchanger-regenerator.

This is achieved by the fact that the vortex tube further comprises axially located mechanical generator polyfrequent sonic and ultrasonic vibrations, running from the cold stream, and its working surface facing the axial diffuser and aperture cold flow, and mechanical sound generator and ultrasonic vibrations, which are both reactor recirculation of the hot stream, the working surface facing axially to allow the grid, and the outer pipe to drain the optimal amount of cold flow in the heat exchanger-regenerator for heat recovery.

In Fig. 1 shows a vortex tube, a longitudinal section; Fig. 2 section a-a in Fig. 1; Fig. 3 cross-section B-B in Fig. 1.

The vortex tube has a ring receiver 1, one side of which is placed tangential to allow the apparatus 2. Cover 3 to allow the device is pressed against the cell energy separation gas 4, fixed in the housing of the receiver. In the Central part of the cover is located in the aperture 5 with the axial di the new vibrations 7, consisting of confused nozzle 8, the resonance chamber 9 and the resonator 10. The resonator for the purpose of regulating one end fixed in the rear wall of the cold receiver (camera cold) 11.

On the hot side of the camera energiesparende to the casing pipe 12 is attached a counter-current heat exchanger-regenerator 14 with the casing 15. In the Central part of the heat exchanger-regenerator inlet recirculating hot thread mounted mechanical sound generator and ultrasonic vibrations 16, from opposite sides, i.e. at the end of the transport zone is fixed axial jet grating 17.

Luggage coldness connected with the outer contour of the heat exchanger-regenerator pipe 18, which is aperture 19 for measuring gas flow going to the recirculation of the heat exchanger-regenerator. Cold stream from the heat exchanger-regenerator is extracted four string ejectors 20 and protrudes into the atmosphere. During the operation and research quantities of mass recirculating cold flow change reset some of its number to the consumer of cold gas or in the atmosphere through valve 21.

To the housing of the vortex tube mounted ejectors and chromel-kopelevich part ejectors are inside buildings mufflers 24.

The workflow of the vortex tube is as follows.

Compressed gas from the network arrives at the receiver of the vortex tube, where measured its parameters, and then in the tangential mehoopany apparatus, where it expands, it speeds up and gets a spin. As further movement of the swirling flow in the swirl chamber energiesparende is the process of energiesparende gas with the formation of two streams, one of which is moving on the periphery of the chamber and having a higher temperature and more pressure comes in the ring receiver and then to the four nozzle inkjet ejectors. Another peripheral part of swirling hot flow (recirculating part) enters the annular gap on the periphery to allow axial lattice and later in efficient heat exchanger-regenerator, which is a cylindrical tube with a continuous spiral finned both external and internal heat transfer surfaces. Fins are vosemnadcatiletnie rectangular tape thread with large same steps. Moreover, the ribs are integral with the pipe wall. It is washed by the hot and cold streams at pressures less giving the ri critical pressure.

Recirculating hot flow, rotating with high circumferential and axial components of velocity, washes the inner fin heat exchange surface, is cooled, decelerated and through axial mechanical generator polyfrequent sonic and ultrasonic vibrations, comprising confused nozzle, the resonance chamber and the cavity, enters the transport area, separated from the heat exchange surface of the annular layer of insulating material. From the transport zone gas enters the axial nozzle grille, microsope which are parallel to the longitudinal axis camera energiesparende. Passing lattice with cylindrical, microplane, the gas is split into smaller streams, accelerated and vigorously blown into pricebuy cavity of the vortex chamber of energiesparende, intensificar it turbulence, improving the efficiency of the process energiesparende. Experiments show that with decreasing diameters of the axial and tangential nozzles of nozzle arrays, the effect of process energiesparende gas in the chamber is improved. This, apparently, is due to the fact that this change sound vibrations, i.e., changes the frequency of the sound, when the amplitude of the displacement of the particles and their amplitude socialno increases.

The conical chamber energiesparende works on two combined principles of individual vortex devices: counterflow vortex ejector and a conical counter-flow vortex chamber energiesparende with axial and tangential deployme lattices. Its optimum performance depends on a large number of factors and is determined empirically.

Vortex ejection effect created by the hot end of the conical chamber energiesparende, increases the expansion rate of the gas vortex tube and the speed of the end of the axisymmetric microapl tangential and axial arrays. They split up and accelerate the gas flow. Because of this increased turbulization of the gas in the chamber energiesparende and as a consequence improve the characteristics of the vortex tube. Experiments show that without axle to allow the grid, the efficiency of the process energiesparende rapidly deteriorating.

When a large number of microsol in the tangential and axial nozzle arrays, which are independent generators of acoustic waves and waves outgoing from the mechanical sound generators, no effect of a single wave on the distribution of the other does not. Each cha way several waves, then, as you know, she is involved in the fluctuations of all waves, i.e., its motion is the sum of the fluctuations of all waves. Thus, the imposition of a large number of waves is the sum of their oscillations at each point of the medium through which these waves, including reflected, pass, i.e., is what is called interference. Due to the interference of the sound waves they composed and give the resulting oscillatory movement with the greatest possible amplitude of the particles in the gas. In the result of the interference amplification of sound energy density at different points in the camera energiesparende increase and will be maximum.

The proposed design of the vortex tube is a device in which polyfrequent sound energy produced by microsemi tangential and axial deployme grates, mechanical-regulatori sound vibrations and other elements of the pipe is separated in the chamber to heat the gas flows of different temperature levels coming from different places of the vortex tube.
