The technical FIELD,

The invention relates to the technology of hydro-processing liquids, having in its composition bonded hydrogen, with destructive transformation of their chemical bonds at the molecular level for various technological purposes and directly relates to a method and device for resonant excitation of the liquid using a hydrodynamic rotary exciter.

The LEVEL of TECHNOLOGY

The prior art method and device for heating the liquid (patent RU 2150055), fashion and Wania (international publication WO 99/36164), using the same hydrodynamic rotary exciter. All these methods include the flow of liquid into the cavity of the impeller rotating inside the stator, the release of liquid from the impeller through a series of outlet openings uniformly distributed on its periphery an annular surface, an annular resonant cavity bounded by a peripheral annular surface of the impeller and the inner coaxial surface of the stator, and the drain of the ring resonant cavity in the expansion chamber. While the nominal value of the radius R of the peripheral annular surface of the impeller and the frequency n of rotation are set depending on the selected number To its outputs according to the following empirical correlations:

R=1,1614 To [mm] (the so-called “active” radius),

n=3,8396 To-1,5106[rpm].

The above correlation obtained from known (for example, from the description of the patent RU 2150055) empirical dependencies

where V [m/s] - circumferential speed of rotation of the fluid at radius R [m] subject to empirical assumptions that t=L, where t [m] - circumferential spacing of the outlet openings of RA is any, empirically numerically equal to the known physical constant fine structure constanttaken in meters.

The latter is in the form of a disk with a peripheral annular wall, which made a number of output holes, evenly distributed around the circumference. The stator has a coaxial the impeller wall, the inlet opening for the fluid, communicated with the cavity of the impeller, and an outlet for discharge of liquid. There is a ring resonant cavity formed by the peripheral annular wall of the impeller and the axial wall of the stator. The stator has a camera team, reported, on the one hand, with its outlet orifice and, on the other hand, with the ring resonant cavity.

DETAILED description of the INVENTION

The method of resonant excitation of a liquid, having in its composition bonded hydrogen to the destructive transformation of its chemical bonds at the molecular level by using hydrodynamic rotary exciter. Be processed liquid is supplied into the cavity 1 (Fig.1) impeller 2 through the inlet 3 of the stator 4. During rotation of the impeller 2 of the processed liquid is being drained from him in the ring resonant cavity 5 is bounded by a peripheral annular surface 6 (Fig.2) impeller 2 and protaglandin on the peripheral annular surface 6 of the impeller 2. Within the ring resonant cavity 5 of the processed fluid continues to rotate relative to the Central axis 9 and is undergoing at this resonant vibrations of sound frequency caused by the interaction of the elementary streams flowing from the outlet openings 8 of the impeller 2, with each other and coaxial with the surface 7 of the stator 4. The treated fluid out of the ring resonant cavity 5 into the collecting chamber 10 and is removed therefrom through outlet 11 of the stator 4. Part of the treated fluid is returned from the ring resonant cavity 5 into the cavity 1 impeller 2 for additional processing. The required dynamic pressure of the fluid is created by the blades 12 of the impeller 2, and optionally, if necessary, by application to external fluid pressure.

When this is observed, the following empirical dependence of the nominal value, resulting from the above well-known dependence (1):

Passive section 5A should be carried out by the impeller 2, facing the team of the camera 10, but it can also be done from the other side of the impeller 2. This additional extension ring resonant cavity 5, as it is established experimentally, contributes to further improving the efficiency of resonant excitation of the liquid and, consequently, improve the quality of its technological processing.

In another preferred embodiment (Fig.4) release the treated fluid from the annular resonant cavity 5 (5A) into the collecting chamber 10 is carried out across remotely fluid flow.

The number returned in the additional processing fluid is controlled by varying orifice bypass ring vortex chamber 5C at its narrowest point and can be 10... 90%, preferably 25... 75% of its full amount, leaving the impeller 2, depending on the required ratio quality/productivity. This achieves the optimal management process hydromechanical processing liquid.

Thus is formed an output annular swirl chamber 5b with centripetal flow of fluid communicated with the team of the camera 10 by-pass hole 23.

In the following preferred embodiment of the circuit internal recirculation of fluid includes a bypass ring vortex chamber 5C formed between the covering disk 17A of the impeller 2 and the stator 4 and connecting the second output of the ring resonant cavity 5 with the inlet of the impeller 2. The number returned in the additional processing liquid can be adjusted by changing the width C (Fig.1) at the output of the bypass ring vortex chamber 5C.

In the preferred embodiment the number To the outlet openings 8 of the impeller 2 is K=1,72205 R d-1where 3d30 - selected techestva of the outlet openings 8 of the impeller 2.

The radial dimension H of the ring resonant cavity 5 can be freely chosen within reasonable limits, but to improve the resonance properties of the preferred empirical value: N=0,91 m [mm], where 10m1 is a selected integer.

The width of the outlet openings 8 of the impeller 2 can be at least half of their district step on the circle of radius R and may vary slightly throughout their radial length.

In this case, rotating the ring resonant cavity 5, the liquid is subjected to a resonance excitation frequency F according to (3). Then rotating fluid passes passive section 5A of the ring resonant cavity 5 and is supplied to the output ring vortex chamber 5b with centripetal flow of the fluid, where the fluid continues to rotate at a peripheral speed corresponding to the known law of conservation of momentum. The output of the ring vortex chamber 5b treated liquid flows through the Central annular bypass hole 23 in the expansion chamber 10 and thence discharged through the outlet 11 for further processing, storage or use.
