DESCRIPTION OF THE INVENTION
The invention relates to the construction of pump-heat generators, which can be used in autonomous closed systems of heat supply of residential, public and industrial buildings, as well as for hot water supply and heating of liquids in technological systems.
The nearest technological solution is a rotary pump-heat generator (patent RU 2159901) , containing a hollow body with a suction nozzle for supplying the heated liquid. Inside the housing there is a rotor in the form of a double-flow centrifugal wheel with holes along the periphery. Concentric to the rotor is a stator with holes. The holes in the rotor are made in the form of circular cylindrical venturi nozzles, and the holes in the stator are in the form of suddenly expanding nozzles.
The disadvantages of the known device is that the liquid is not sufficiently heated in one pass through the heat pump. To increase the temperature of the liquid, it is necessary to pump it repeatedly through the pump-heat generator.
The technical task, the solution of which is directed to the invention, is the creation of a device through which the processed liquid is repeatedly subjected to factors of influence on it, which results in intensive heating of the fluid in one pass through the hydrostatic pump-heat generator.
The object is achieved in that in a rotary hydrostatic pump-heat generator having a complete housing with a suction connection for supplying the heated liquid and a delivery branch for withdrawing the heated liquid, and a rotor and stator located in the housing concentrically to each other forming a channel connected to the holes , In the annular channel on the side of the rotor and the stator, there are perforated recesses inside which elastic hollow spheres are arranged and rings with holes formed therein in the form of converging nozzles facing inwardly of the annular channel, and the bases of the supply pipes for the heated liquid and Branch are located in the annular channel.

Nozzles of the rotor and stator, from which it can be seen that the most advantageous expansion angle is in the range of 6-8 o . At these angles, the head loss during movement in the nozzles is minimal. Below the graph is a diagram of the nozzle opening.
THE DESCRIBED THERMAL DEVELOPER DESCRIBED BY THE FOLLOWING
As the shaft 6 (FIG. 1) rotates, the heated liquid passes through the suction nozzle 2 of the hollow body 1 to the ring of the rotor 7, the liquid fills the holes of the rotor 7 and the annular passage between the ring of the rotor 7 fixed to the rotor 5 and the stator ring, and then the holes In the stator ring.
Under the action of the centrifugal force, the liquid in the nozzle opening of the rotor is ejected into the annular channel between the rings of the rotor and stator, and when aligning the holes, it rushes into the nozzle opening of the stator. When the liquid moves through the nozzle orifice of the stator, the hollow ball 15 deforms under the action of a hydraulic shock 11 (FIG. 2). In order to prevent the liquid from spreading out at the time of the hydraulic impact, the opening 10 of the housing 1 and the stator orifices are sealed by a gasket 8, and the rotor holes are similarly sealed by the gasket 9.
The liquid ejected from the rotor nozzle under the influence of kinetic energy forms a hydraulic piston 12 in the rotor nozzle with the formation of a rarefaction zone 13. In the closed volume of the zone 13, it occurs under the action of a reduced pressure, saturation of the liquid with its vapor and the formation of cavitation bubbles.
When the rotor orifice is displaced to the next stator orifice (FIG. 3), liquid is ejected from the stator orifice, under the action of the energy of the hollow ball 15, which, taking the original form, conveys kinetic energy to the fluid. Since there was a rarefaction in the rotor hole, the liquid from the nozzle opening of the stator rushes into the holes of the rotor. A sharp increase in pressure in the zone of hydraulic shock 14 causes the vapor of the liquid and cavitation bubbles to condense, and the kinetic energy of the fluid deforms the hollow sphere 16 in the rotor hole.
When the liquid filled the vacuum zones 13 of the rotor and the stator at the moment of condensation of the liquid vapor, a sharp decrease in the volume of the liquid vapor occurs. It is known that the volume of condensate is 400-1500 times less than the volume of steam equal to it by mass.
The pressures arising from the condensation of vapor-gas and cavitation bubbles can be determined from the formulas:
All the aforementioned pressure values occur in the condensation of spherical cavitation bubbles. In the moving fluid, and even more so when the bubbles condense under hydraulic shock conditions, their surface deforms and changes in shape.
Condensation of deformed cavitation bubbles generates cumulative trickles, the pressures in which can exceed the pressure from the condensation of ideal bubbles to a dozen times. Taking into account changes in the volume of steam during condensation (400-1500) and the value
Such processes of vaporization and condensation, hydraulic shock and cavitation occur in the rotor and stator nozzles many times with increasing pressure from the suction nozzle 2 to the nozzle 3. The heated liquid is directed to the discharge nozzle for the intended purpose.
In order to reduce friction losses in the nozzles and, consequently, to reduce the head and to prevent the jet from escaping from the nozzle walls, the expansion angle should be in the range of 6-8 ° .
By regulating the flow rate of the flowing liquid, the pressure at the input to the pump-heat generator, and the rotor speed, you can set the energy-saving mode of liquid heating.
The level of metal working at modern machine-building enterprises makes it possible to produce rotor hydrostatic pumps-heat generators based on serially produced sand, ground and other pumps having a large radius of impeller and its height
This pump-heat generator can be used for heating and hot water supply of objects remote from power supply facilities, and for heating process fluids.
Such sources of heat supply are necessary in the areas requiring preservation of the environment cleanliness and maximum safety in the places of its development (hospitals, holiday homes, etc.)
