DESCRIPTION OF THE INVENTION
The invention relates to heat power engineering and can be used in liquid heating systems used for heating residential buildings and industrial facilities.
At present, heat pumps are increasingly used as heat generators. When working in these devices, the reverse cycle is performed, i.e. There is an absorption of heat from the environment with the subsequent transfer to its body with a higher temperature.
Known are devices of heat pumps that use changes in the physical and mechanical parameters of the medium, in particular pressure and volume, to generate thermal energy.
A rotary heat pump is known , protected by the RF patent No. 2159901 (published on November 27, 2000) and a heat-generator pump protected by the RF patent No. 2160417 (published December 10, 2000) having a hollow body with a suction connection for supplying the heated liquid and a discharge pipe for the heated Liquids located inside the body of the rotor in the form of a centrifugal wheel with holes along the periphery and a stator with holes installed coaxially to the rotor.
Known is a cavitation-vortex heat generator protected by the RF certificate for utility model No. 29127 (published on April 27, 2003) having a housing with nozzles for supplying heated liquid and for removing heated liquid located inside the rotor housing, made in the form of two coaxial holes punched through holes With a gap in relation to each other on independent shafts, having independent drives and rotating towards each other. For the prototype of the claimed invention, a cavitation-vortex heat generator (RF patent application No. 2002119773/06, 7 F 24 J 3/00) is selected, comprising a housing having nozzles for supplying a heated liquid and withdrawing a heated liquid; a stator located inside the housing; The form of one or more annular disks perforated through holes, a rotor made in the form of two perforated through holes of discs installed with a clearance relative to each other on independent shafts having independent drives and rotating towards each other.
The technical result , to which the claimed invention is directed, is an increase in the efficiency of heating due to the intensification of the heating process.
This technical result is achieved by the fact that liquid heating occurs successively in several fluid passage zones through the structural elements of the cavitation-vortex heat generator: in two swirl pumps, in two cavities between the starter grids and rotor annular gratings, in the cavity between the rotor gratings.
The figure shows the scheme of the cavitation-vortex heat generator.

The cavitational-vortex heat generator consists of a casing 1 with supply 2 and outlet 3 nozzles in which a stator consisting of two annular perforated through holes 4 disks and two coaxial rotors 5 installed between the stator disks with a gap with respect to each other and the stator disks mounted On independent shafts 6 having independent independent drives and rotating in opposite directions. Each of the rotors 5 is made in the form of a stepped disk with a thickened central part 7 and a thin peripheral part 8. The annular discs of the stator are mounted in the housing coaxially with respect to the protrusions of the central parts 7 of the rotors. On the outer plane of the central part 7 of the rotor disk, radially directed blades 9 are closed, closed by an annular plate 10, forming a vortex pump. In this case, the outer diameter of the annular plate 10 is equal to the diameter of the thickened central part of the rotor, and the inner diameter is larger than the diameter of the drive shaft, forming the inlet opening 11 of the swirler pump. The inlet nozzles 2 are located on the side surfaces of the housing 1 opposite the inlet ports 11 of the swirler pumps, and the outlet nozzles 3 are located on the peripheral surface of the housing 1 against the thin peripheral parts 8 of the rotor disks. |
The cavitation-vortex heat generator works as follows.
The liquid, due to the rarefaction created in the swirler pumps from the supply nozzles 2 through the inlet openings 11, enters the interlobar space (zone A), where the primary energy excitation of the molecular structures of the liquid occurs due to the appearance of local vorticity regions, cavitation zones and high-speed reorientation of molecular structures And as a consequence the first stage of heating.
Then the liquid enters the cavity in front of the grids (perforation) of the annular discs 4 of the stator (zone B), where fluid braking and overpressure occur. Here the molecular structures of the liquid tend to return to the initial state, which leads to the release of energy.
Further, the liquid rushes into the channels of the 12 lattices of the annular stator disks, through which it passes in the pulsating mode with the opening frequency of the channels occurring when the holes of the perforation of the annular stator discs coincide with the perforations of the rotor disc, and enters the cavities between the movable discs of the rotors and the fixed annular disks of the stator Zone B), where a primary vortex field appears.
In these cavities the next stage of the reconstruction of the molecular structures of the liquid takes place. The fluid vortices formed in these cavities have a speed of rotation about 35,000 revolutions per second around its axis. The cavitation that occurs here contributes to the release of energy, which is expended on heating the liquid.
Passing through the open channels of fixed gratings of annular stator discs and movable gratings of rotors into the cavity between the rotor grids rotating in opposite directions in parallel planes (zone D), the liquid acquires a strictly oriented rotational motion. Here a lot of "vortex cords-tornadoes" are formed, in which the molecular structures of the liquid, in addition to strict orientation, are subject to the influence of "disturbing" factors. This is a pulsating pressure change corresponding to the opening frequency of the channels of the stator ring disc gratings, and the interaction of the boundary layers of the "tornado" where the oriented molecular structures collide. All this leads to the allocation of a large amount of energy directed in the generator to heat the liquid.
The "whirlwind-tornado" formed here, according to calculations, have a high speed of rotation - more than 70,000 revolutions per second. As a result of the centrifugal forces acting here, a vacuum arises along the axis of such "tornado cords", which leads to the formation of cavitation bubble-vesicles, i.e. Cavitation, which occur at a frequency corresponding to the frequency of the closure of the channels of the stator ring disc arrays, i.e. Lowering of pressure. The collapse of cavitation bubbles according to Rayleigh's studies is accompanied by pressure jumps in the boundary layers to 10,000 atm and temperatures up to 5000 ° C. The physicochemical changes of both molecular structures and energy parameters of molecular interactions occurring in the liquid lead to the release of a large amount of energy.
"Cord-tornado" occupies the entire volume between the grids of the rotors. As a result, a "cavitational vortex field" is formed, which, under the action of centrifugal forces, rushes to the outer boundary of the rotor gratings and further to the output tube of the generator. Due to the high speed of the processes passing through the generator and the high velocity of the fluid, the "cavitational vortex field" does not affect the elements of the generator structure.
As a result of the effect of cavitation on high-velocity vortex streams of high-frequency pressure pulsation, the equilibrium (latent) state of the energy interaction of liquid molecules is disturbed, which leads to the release of a large amount of energy.
