The technical field to which the invention relates.
The present invention relates to heat engineering, in particular to methods and devices for heat produced otherwise than as a result of combustion of fuel, and can be used in heating systems and domestic hot water in residential and industrial buildings, as well as to pre-heat water at power plants and nuclear power plants and to improve the rheological properties of oil and oil products.
The level of technology
Known friction methods of heating liquids, which consists in the fact that heat is generated as a result of friction from each other and/or liquid to solid, driven in a vessel with liquid. One such method is disclosed in the author's certificate of the USSR No. 1627790, F24J 3/00, publ. in 1991, the Disadvantage of this method is that due to the loss of energy efficiency of heat (amount of heat out of the heated fluid to electrical or mechanical energy consumed by the device), less than one.
Also known methods of heating liquids, in which the efficiency of the heating exceeds unity. This cavitation vortex methods. Device for their implementation are divided into two types - rotary and vortex.
The rotary method of heating liquids, as well as devices for their implementation are disclosed in the patent is EN 2054604, F24J 3/00, Hoards A. F., 20.02.1996, and in the patent RU 2165054, F24J 3/00, Potapov Y. S. and others, 10.04.2001, the Device according to patent RU 2054604 consists of a body of cavitation generator, which is mounted on the shaft impellers of centrifugal pumps with perforated rings. The impellers are rotated by an electric motor. Coaxial them are stationary perforated ring, slightly larger in diameter, fixed in the housing of the heat generator. The case has two holes for supplying heated liquid and drain it from him.
The method according to patent RU 2054604 is that the liquid is fed to the input of the heat source and create in the area of its processing cavitation bubbles and turbulence that occur due to the periodic change of the fluid pressure during the flow through mutually intersecting the perforation holes of the rotating and stationary rings heat source. When this liquid is heated by the friction of the walls and the surface of the perforated wheels, and cavitation.
Heat generator according to the patent RU 2054604, due to presence of impellers of centrifugal pumps, he creates the pressure required for supplying heated fluid to the consumer, and there is no need for a circulation pump. Using the device according to patent RU 2054604 you can reach values of efficiency equal to 2-4 and even higher. This hundred is ulitsa possible due to the fact, what you receive excess energy in the flow cavitation bubbles nuclear reactions of synthesis of nuclei of hydrogen atoms (protons)within the composition of the water. Confirmation of this is found to exceed the dose of ionizing radiation from heated in such a device the liquid above the background dose of ionizing radiation.
The disadvantage of this device in patent RU 2054604 is its complexity and the need for protection against ionizing radiation of the entire heating system.
More simple and safe method is to generate heat, and a device for its implementation disclosed in the patent US 5188090, F24C 9/00, J. L. Griggs, 23.02.1993, According to the method proposed to heat the water, passing it through the gap between the mating surfaces of the stator and rotating it relatively monolithic cylindrical rotor. On passing water act cavitating bubbles, which occur in numerous cavities, drilled on the cylindrical surface of the rotor. According to the method according to patent US 5188090 water is heated to 80-88°C. if the initial temperature of 20-60°C.
According to the method according to patent US 5188090 quantity of heat generated in the device for its implementation, and brought out of it the heated fluid to the consumer, 1,17 times more than the amount of electrical energy, is AutoRAE consumes the electric motor, resulting in a rotation of the rotor of the device. Naturally, the less water used, the higher the temperature of the water in the pipeline, diverting it to the consumer.
The drawback of the method according to patent US 5188090 is the low efficiency of heating the liquid in comparison with the efficiency of its heating by the way, opened in EN 2054604. This is due, firstly, to the fact that during the rotation of the rotor in the device described in US 5188090, not crossing jets of water holes of the perforation, as in the device described in EN 2054604. Another reason for the decrease in the efficiency of water heating on the way, opened in US 5188090, is that the pump for pumping heated water through the heat source and feed it next to the user set in the schema of the pipeline before boiler and attached to the pipe that goes to the inlet of the heat source. Rotary heat generator in the device according to US 5188090 can not pump heated water without the aid of an external pump, since the openings for entry and exit of heated water in the boiler are at the same distance from the axis of the shaft and the centrifugal forces acting on the water during the rotation of the rotor are balanced. Work by pumping heated water conducts external pump, pumping the first fluid in the heat source, and then continue all the pipelines of the vessels of the scheme. The pressure of the heated water will be greatest at the entrance to the heat source. At the exit of the boiler the water pressure is slightly lower than the entrance, but higher than in piping systems and vessels that are located further under the scheme during the heated water after the heat source. There's a lot more atmospheric pressure of the ambient air. And the greater the water pressure, the less, as is known, the intensity of cavitation processes in it, for cavitation bubbles "zadumivaetsa" this pressure and do not develop further.
Another analog of the present method and apparatus for producing thermal energy is the heat generation, and device for its implementation disclosed in the patent RU 2045715, F25B 29/00, Potapova Y. C., 1995 This method is that the water to be heated, serves to heat and form a swirling motion of the water in it while providing a cavitation mode of its flow by increasing its flow resulting sound vibrations. When this water is heated to a temperature greater 63°C.
As a heat source according to the patent RU 2045715 use vortex generator. In all examples, the water to be heated is fed to the input of the heat source using an external pump, forcing it into heat.
The drawback of the method according to Acento EN 2045715 is the low efficiency of heating the liquid, reaching the values of only 1.2 to 1.4 by heating water in a vortex heat generator.
The reason of low efficiency of heating water is that the water pressure in the vortex heat generator (up to 5 ATM) is too high as at the entrance to the heat source, and the output from it. And the greater the water pressure, the less, as is known, the intensity of cavitation processes in it, for cavitation bubbles “zadumivaetsa” this pressure and do not develop further.
The water pressure at the inlet of the device according to patent RU 2045715 make such a high order due to this pressure to provide the necessary high speed of water flow in the cochlea (swirl) of the vortex tube. When this pump for pumping heated water, mounted in front of the generator and attached to the pipe that goes to the inlet of the heat source, not only should perform work by pumping water through the heat source, but also work on pumping this water further along the pipeline, the discharge of heated water from the heat source to the consumer. The latter also have a significant resistance to the flow of water, so the water pressure at the outlet of the heat generator is also significantly above atmospheric.
The closest analogue of the present invention disclosed in the patent of Russian Federation №2132517 S1, date of publication - 27.06.199. Of the said patent a method of obtaining thermal energy, including the flow of fluid under pressure from the pump in a vortex tube to receive the cavitation vortex flow and the subsequent direction of the cavitation vortex flow in the fluid container.
Also of the said patent a device to obtain heat energy, including the capacity of the heated fluid, a vortex tube and pump the fluid in a vortex tube.
Disadvantages closest analogue is that the cavitation vortex flow is formed not at the maximum possible intensity of turbulence, and that there is no resonant cavitation mode of the flow.
Disclosure of inventions
The present invention is to eliminate the above disadvantages.
The technical result of the present invention is to increase the speed of heating the liquid and improving the heat transfer in the cavitation vortex heat generator due to the intensification of cavitation processes in it and create a resonance in the vortex tube.

Shown is the technical result is achieved by a method of producing thermal energy, including the flow of fluid under pressure from the pump in a vortex tube to receive the cavitation vortex flow in which the concentration and the connection of the molecules of the liquid into clusters, and the subsequent direction of the vortex cavitation flow in the liquid reservoir. Thus the fluid flow before entering the vortex tube is directed through the slots, which are placed at an angle to the Central axis of the vortex tube along its perimeter, tangentially spin through these slots and is subjected to ultrasonic irradiation and subsequent depression in the conditions of resonance.
In addition, you can use the slots that are placed at an angle of 45° to the Central axis of the vortex tube along its perimeter. For tangential swirling flow can be used slots any complex shape, for example elliptical.
The method can be carried out with a liquid circulation in a closed circuit and selection of thermal energy in the heat exchanger external heat transfer.
The method can create additional suction through the outlet openings, which can be performed at the end of the vortex tube, and the suction port of the pump, which can be placed in a vessel heated liquid in the zone of the end of the vortex tube.
This technical result is also achieved midrange is t device to obtain heat energy, including the capacity of the heated fluid, a vortex tube and pump the fluid in a vortex tube. The device includes installation of ultrasonic vibrations of the vortex tube which is placed in a container of heated liquid, and on the perimeter of the inlet of the vortex tube are slits.
The entrance of the vortex tube may be made in the form of a cone, located tangentially with respect to the inner edges of the vortex tube.
At the entrance to the vortex tube in its center can be made through the recirculation fluid.
The vortex tube can be provided with the outlets, thus the output of the holes can be square smaller than the slot, 1.5 times.
The device may further comprise a circulation pump, the inlet of which is located in the hot zone of the heated liquid.
The device may further comprise a heat exchanger for selection of heat in the external heat transfer system.

The implementation of the invention
The flow of heated fluid through the small ring is carried out by sucking it out from the trojstva and by this reducing the fluid pressure in the device.
The suction of the heated fluid from the pump device, the feed next to the device, leads to a decrease in pressure of the liquid at the outlet of the device and partly inside it. And this leads to the intensification of cavitation processes in it, as the latter are more intensive, less than the static pressure of the liquid and the greater the pressure differential between the input and output devices. At constant pressure of the heated liquid inlet device provided or a pump, which supplies the liquid into it, or atmospheric pressure of the air in the vessel to a source of liquid (in the absence of a forcing pump, suction heated fluid from the device leads to higher pressure drop between input and output devices. Under the influence of high-frequency radiation is output at the resonant mode.
Mode resonance heating is intense. All this leads to the intensification of cavitation processes in the device, and consequently, to improve the efficiency of heating the liquid in it. In addition, reducing the pressure of the heated liquid in the device and the creation of the vacuum leads to a reduction of the pressure of this fluid on the seals or mechanical seals pump, which increases the lifetime of their service.
In Fig.1 to illustrate the preferred implementation of the FPIC of the BA and the device to obtain heat energy by pumping fluid pump through the pipe, connected to high-frequency emitter.

In Fig.2 shows an example implementation of the device resonant type with a chamber 1 in which is mounted an ultrasonic emitter 13 of the cone 14, the flange 15, an inclined hole 16 hole 17, vortex tube 10, the dispenser 9, the hole 18.
In Fig.3 shows the swirl chamber 1 with the cover removed, type A, the slots 16 at an angle, the hole 17, the cone 14, the flange 15, the housing 20.
The proposed method is as follows.
1. The fluid to be heated (water, transformer oil, oil, antifreeze or other), is poured into the vessel to a source of fluid having a volume greater than the total volume of all cavities in the device for heating the liquid and attached piping.
2. Fill with liquid to be heated, all of the cavity and the piping device for heating the liquid, which includes a vortex tube.
3. Include a motor that drives the pump, pumping the heated liquid in a vortex tube, and secure the offer due to the design of the pipe swirling motion to the liquid in it at the maximum possible in this scheme the intensity of the turbulence.
4. Simultaneously, the pump performs a suction heated liquid from the pipe and feed it into a vessel drive heated liquid. It is necessary to use such a pump such as a centrifugal or gear), which can create a negative pressure in its inlet pipe and to reduce the fluid pressure in the outlet of the heated fluid from the pipe.
5. Include the installation of ultrasonic vibrations. By adjusting the frequency of oscillations in the vortex tube get resonancia cavitation mode of the flow through the device.
6. Carry out heating of the liquid to the desired consumer temperature due to the return of her circulating pump in the return line from the vessel with the heated liquid in the vessel to a source of liquid and feed it through a closed circuit back to the input devices (pipes). The consumer fluid gives up heat through the heat exchanger. The heat exchanger may be performed, for example, in the form of a battery, radiator, plastic heat exchanger or in any other form.
Heating of the liquid shown in table 1, is carried out using a centrifugal pump with an electric motor with a capacity of 5 kW, a pressure of 40 m and a flow rate of 25 cubic meters per hour, made in China. Of the filled liquid tank 2 through the valve 8 (the valve) it arrives at the inlet of the pump 5, the liquid is od pressure in the pipe 2 through the valve (the valve) 8 is fed tangentially into a vortex chamber 1 of the device through the cone 14.
In the vortex chamber 1, the liquid starts to rotate, and getting into the slot 16 receives the acceleration. High speed four (or more) of the fluid flow creates a vortex cavitation effect of the vortex tube 10. By and large the radius of the vortex tube 10 is formed by a hot stream, which through holes 18 comes in (capacity) 3 and simultaneously enters at the inlet of the pump 5, which creates a negative pressure in the vortex tube, contributing to the formation of cavitation.
When the pump power meter defined consumed electric power W2 specified in table 1, as well as by measuring three-phase meter the amount of electricity consumed by the motor during heating the liquid.
Periodic rapid contractions and expansions, the cavitation vapor bubbles occurs, in accordance with the laws of thermodynamics, energy transformation into heat, which leads to rapid heating of the liquid.
As shown by measurements of many scientists and researchers (see Semenov A., Stoyanov P. Zvukovaya or light taken out of the vacuum. - Technique for youth, 1997, No. 3, S. 4-5.; and Margulis, M. A. Zvuchanie reactions and sonoluminescence. - M.: Chemistry, 1986, - 288 C., the temperature in the center kropyvysche bubbles can reach thousands of degrees Celsius. This leads, as is well known, sonoluminescence the luminescence of liquids. In cavitation bubbles of heated liquid go thermochemical reactions. Thermochemical reaction is accompanied by evolution of heat, which is used for heating the liquid in the proposed device. The energy of these reactions is additional to the energy that is released during the operation of the device.
Therefore, the efficiency of heating the liquid in the claimed method and device (the ratio of the obtained heat energy expended electric) exceeds unity. It is known that during the rotation of the liquid, in addition to cavitation, the processes of synthesis of water molecules in clusters, and when they speed rotation several times with the release of thermal energy (see Potapov Y. S., Potapov, S. Y. rotational Energy. K., 2002, 353 S.).
