Description

Field of Technology:

The invention relates to energy and can operate in a heat generator with simultaneous pumping of a heated fluid. Rotary, cavitation, vortex pump-heat generator can be used for heating liquids in heating systems and hot water supply. In addition, the heat pump can be used for mixing immiscible liquids, preparing suspensions and emulsions, as well as for disinfecting liquid food products, natural and waste water, domestic and agricultural effluents.

The rotary, cavitation, vortex pump-heat generator has a housing, inside of which a rotor (or rotors) is located on the drive shaft, on the peripheral surface of which Levavasser ultrasonic emitters of various configurations are located.

Some emitters are connected by channels to the suction cavity or suction pipe, providing pumping of the processed fluid.

The peripheral arrangement of the incident edges of the emitters provides an intensive flow of liquid inside the emitters, ensuring, due to the vortex flows, zones with reduced pressure, which contribute to the appearance of cavitation bubbles, and zones with increased pressure, which ensure intensive collapse, and the disappearance of cavitation bubbles.

Known heat generator for heating fluid, Russian patent No. 2301381 dated 2007 06. 20, containing a cyclone connected to the pump, at the opposite ends of which the main and additional cylindrical bodies are installed coaxially with the brake device each, while the outlet openings of the bodies are interconnected bypass pipe, and the brake device in the main cylindrical body is installed with the possibility of axial movement relative to the body. Liquid under pressure of 0.4-0.6 MPa is fed into the cyclone through an injection pipe. The heating of the liquid is carried out due to friction forces with subsequent vortex separation into two flows. The warmer stream is directed to the heating system, and the colder stream is returned to the suction zone of the heat generator.

The disadvantages of the known device are:

- For the formation of vortex motion in the heat generator for heating the liquid, it is necessary to have a pump that provides, at a known performance, a fairly high pressure of 0.4-0.6 MPa.

- The vortex movement of the liquid in the body of the heat generator does not provide the occurrence and collapse of cavitation bubbles.

The hydrodynamic heat generator is known, patent of Russia No. 2301946 dated 2007. 06. 27, comprising an injection inlet pipe, a housing having a cylindrical part, with an end face attached to a cyclone accelerator and a fluid swirl, in the opposite base of which a braking device is installed. The fluid flow through the outlet slit-like opening of the injection pipe enters the cyclone, accelerates and swirls, acquiring a vortex-like shape, and propagates along the cylindrical part of the heat generator to the braking device, where there is sharp braking, and then through the outlet it enters a closed system. Heat generation in the heat generator is ensured by:

- hydrodynamic effect (acceleration-braking of the working fluid);

- the effect of a hydrodynamic “explosion”, which ensures an increase in the temperature of the liquid in the vortex flow.

The disadvantages of the known device are:

- the presence in the fluid heating system of a separate pump that provides fluid to the heat generator;

- lack of zones of occurrence and collapse of cavitation bubbles.

There is a known method of heating a fluid, Russian patent No. 2225967 dated 03/20/2007, including dividing the total flow into several flows, twisting them in a coaxial cylindrical channel, while the swirling directions are chosen opposite and the two of these flows are collided.

Heat is generated by the formation of discontinuities and cavitation cavities formed between the layers of liquid.

The disadvantages of the known method of heating a liquid are:

- the presence of a pump that delivers fluid to the heat generator;

- the formation of cavitation zones of the fluid flow not in the zones of reduced pressure, but in the braking zones of counter-swirling flows under pressure.

Known heat pump, patent of Russia №2319911 from 2008 03.20, cavitation-vortex type with input axial and output peripheral hydraulic channels, on the shaft of which, between the housing end surfaces with a guaranteed clearance, is located at least one disk on the end surfaces of which are made holes (working chambers), symmetrically located relative to the axis of the shaft, the holes are also made on the housing end surfaces.

Part of the holes are interconnected by end surface channels, providing a pumping ability of the device.

The heat generation in the heat pump is ensured by the occurrence of a potential difference between the surfaces of the disk and the casing, the vortex motion of the liquid in the wells, the disk and the casing, and magnetic effects on the electrically conductive liquid.

The disadvantages of the known device are:

- the end position of the holes on the disk and the housing does not provide equal working conditions for the holes (the closer to the axis of the disk, the less intensive the processes are in them);

- insufficiently organized movement of fluid in the wells;

- the difficulty of providing magnetic processing of the liquid.

A device for heating a fluid is known, Russian patent No. 2332618 dated 2008. 08.27, comprising a fixed body with a cylindrical cavity and a cylindrical rotor located with a gap in this cavity, which is rigidly mounted on the shaft with the possibility of rotation and has a certain number of irregularities on the cylindrical surface or holes, and the housing has at least one inlet and one outlet channel. In the housing, adjacent to the first rotor, a second one is installed similarly to the first.

The rotors are mounted with the possibility of opposite rotation from independent drive motors. On the cylindrical holes of the rotors are rows of blind holes and rectangular grooves, the smaller side of which coincides with the radius of the rotor.

Heat generation in a device for heating a fluid is carried out as follows: after filling the device with a fluid medium, motors that rotate the rotors in the opposite direction are turned on. Opposite directions of rotation of the rotors provide unidirectional movement of flows, their combination and further movement in one direction. The accelerated flow enters the cylindrical cavity and is inhibited by the release of thermal energy on the end walls of the rotors. In the zone of blind holes between the housing and the cylindrical surfaces of the rotors due to the discontinuity of the continuity of the flow and the resulting vortex funnels, heat release processes occur. In the area of the conical hole that combines the cylindrical cavities, a collision of two rotating fluid flows occurs, which is also accompanied by the release of thermal energy.

The disadvantages of the known device are:

- the presence of two drives for rotating the rotors of the device in opposite directions;

- the presence of blind holes on the peripheral surface of the rotor contributes to the swirl of the liquid without a clear formation of the zones of rarefaction and zones of high pressure necessary for the emergence and collapse of cavitation bubbles.

The advantage of the device is the presence of radial tapering channels, providing independent pumping of the heated medium.

A heat generator is known, patent of Russia No. 2221200 dated January 10, 2004, of cavitation action, consisting of a centrifugal nozzle, the input of which is connected to the output of the stimulating pump, and its output nozzle - to the flow braking channel in communication with the input of the stimulating pump.

Heat generation in the heat generator is carried out as follows: from the pumping pump, the fluid flow enters the nozzle and, rotating relative to the nozzle, leaves the nozzle and into the braking chamber, where a low pressure zone forms along the axis and cavitation cavities form. Further, in the chamber, the flow rotates towards the nozzle and is directed to the periphery of the chamber. Due to the circulation of the flow between the zones of low and high pressure, an intensive collapse of cavitation cavities occurs, which leads to heat generation and heating of the liquid.

The disadvantages of the known heat generator are:

- complexity in the design;

- the source of cavitation is the zone of the brake chamber distant from the fluid inlet, made in the form of a Loval nozzle, or a sharp narrowing, which is not a source of intensive formation of cavitation bubbles.

The invention is known - broadband hydromechanical dispersant generator, Russian patent No. 2179078 from 02/10/2002, containing the inlet and outlet nozzles and a swirl chamber between them. The vortex chamber is made of a toroidal shape with a variable section in the azimuthal direction of the cross-sectional shape with the possibility of deformation (regulation) of the form. Frequency generation is carried out as follows: the working fluid under static pressure is fed through the inlet pipe into the vortex chamber, where it is rotated - vortex motion. Moreover, in different parts of the vortex chamber, oscillations of excess pressure and vibrational velocity of various frequencies are generated: in places with a small radius of curvature, oscillations with a high frequency are generated, and in places with a large radius of curvature - with a lower frequency.

The disadvantages of the known device are:

- the need to have a pump for supplying a liquid medium through a dispersant generator;

- low efficiency of the device due to the presence of a large transit stream through the generator-dispersant.

Known sonar generator, Russian patent No. 2077960 from 04/27/1997, containing a vortex chamber, an inlet part and an outlet part with a channel in the form of an expanding cone. The generation of acoustic vibrations is carried out as follows: the fluid flow under excess pressure is directed to the resonance chamber. The configuration of the flow part of the generator accelerates the outflowing fluid flow and excites acoustic vibrations in it, as a result of which turbulence of the environment occurs in the expiration zone of the activated liquid stream with the occurrence of cavitation phenomena in it, which contribute to the intensification of the processes of dispersion and washing of contaminated filter materials (granular anthracite, quartz sand, ion exchangers, etc.)

The disadvantages of the sonar generator are:

- the need to have a pump for pumping the processed medium;

- low efficiency of the device due to the presence of a large transit stream through the sonar generator;

- there is no description of the process of formation of acoustic vibrations and why the vortex toroidal chamber is resonant.

Known heat-generator of shock-vortex type, Russian patent No. 2336470 dated 10.20.2008, containing an inlet nozzle, cups with one and a half cavities, a mixing and separation chamber, diffusers, an additional inlet nozzle located opposite the first and separated from it separation and mixing chamber.

In the input nozzles and one and a half cavities, swirlers with the opposite direction of twisting are installed.

Heat generation in a shock-vortex-type generator occurs as follows: the opposing arrangement of the inlet nozzles is due to the need to ensure a shock collision of two fluid flows, which allows activating the process of heating the liquid in the separation and mixing chamber.

The disadvantages of the heat generator shock-vortex type are:

- the need to have a pump for supplying fluid to the inlet nozzles;

- the presence of a shock wave at the meeting point of the liquid jets, preventing the formation of cavitation bubbles.

The hydraulic heat generator is known, Russian patent No. 2134381 dated 08/10/1999, including an input swirling device connected to a vortex tube body, a heated fluid outlet pipe, a vortex tube body provided with longitudinal cylindrical grooves.

Heat generation is carried out as follows: when a fluid is supplied through an input swirling device, its movement acquires a vortex character, and by the moment the vortex tube enters the casing, the fluid velocity increases.

Further, the liquid, washing the inner surface of the body, moves in a spiral in the direction of the bottom. Part of the liquid, filling the longitudinal grooves, also makes a spiral-like motion in them, interacting with the main stream.

This interaction of rotating fluid flows significantly intensifies the conversion of the energy of motion of these fluid flows into heat.

The disadvantages of a hydraulic heat generator are:

- the need to have a pump for supplying fluid to the inlet swirling device;

- the speed of the rotational movement of the fluid along the length of the body of the vortex tube is not the same;

- longitudinal cylindrical grooves do not have partitions, which significantly reduces heat transfer due to a decrease in the speed of rotation in the peripheral from the entrance part of the body of the vortex tube.

A device, a pump-heat generator, patent of Russia No. 940297 of 25/06 from 08/09/1994 (PROTOTYPE), having a hollow body with a suction pipe for supplying heated and discharge for removing heated fluid and a hollow rotor cantilever inside the housing on the rotation drive shaft is known equipped with at least one means of influencing the liquid to heat it.

The heat generation in the heat pump is as follows. After connecting the heat source pump to the drive and to the heat consumer, for example, into a closed local heat supply system, closed by water or another heat carrier (such as antifreeze), water enters the housing through the suction pipe and flows through the central hole in the rotor into channels and “pockets” .

At the same time, the liquid in the "pockets" is under the influence of two main forces:

- centrifugal force, seeking to "suck" the contents of each of the recesses;

- inertial forces from rotation, trying to "clog" this liquid content in the recesses ("pockets").

Since fluid constantly flows past the recesses while the rotor is operating, the contents of the recesses are updated in an oscillatory mode, which is accompanied by intensive heat generation near the channel exits.

The positive qualities of the heat pump are:

- the presence of radial channels that allow you to independently pump the heated fluid;

- the placement of means of influence on the liquid in the rotor of the heat generator.

The disadvantages of the heat pump are:

- pumping a large amount of water through radial channels to ensure the occurrence of vacuum in the recesses ("pockets");

- the absence of centers or zones of cavitation bubbles and their disappearance, which could be a powerful source of thermal energy in the heated fluid.

Disclosure of the invention.

The technical problem to which the invention is directed is the creation of a device in which a liquid or suspension was independently pumped, as well as repeatedly subjected to cavitation in cylindrical ultrasonic emitters of Levavasser located on the peripheral surface of the rotor.

Moreover, ultrasonic emitters must be active working bodies, they must run onto the fluid with sharpened edges, and the processes of formation and collapse of cavitation bubbles would be carried out both inside the Levavasser emitters and in the fluid flowing past the emitters due to the sharpening of the input edges of the emitters when a “wedge tone” is formed.

The technical result that can be obtained by carrying out the invention:

- repeated "visit" of the emitters with each particle of the liquid or suspension;

- increasing the density of cavitation due to the sequential cavitation effects on the liquid of the Levavasser emitters by several rotors mounted on one shaft.

It is known that vortex cavitation occurs in water in whirlpool zones at a whirlpool velocity of 10–15 m / s. Due to the strong rotation of the water moving together with the vortex, and under the action of centrifugal forces, the water is discarded to the peripheral zones of the vortex. The size of the rarefaction zone and the magnitude of the rarefaction in the center of the vortex depend on the velocity of the fluid, and if you try to get vortices with a fluid velocity of more than 20 m / s in unlimited space, then usually the cavitation cavity becomes so large that instability occurs and the vortex collapses.

When liquid flows on the wedge-shaped edge of a solid plate or on the sharp edge of the inlet, for example, a Levavasser ultrasonic emitter, a “wedge tone” appears.

If you move the plate with the sharpened edge forward in the liquid or the ultrasonic emitter with the sharpened edge, then a "wedge tone" appears as when the liquid is leaking.

A “wedge tone” is an ultrasound that occurs in water when it leaks onto a sharp edge sharpened at an angle of 30 °.

A jet of liquid, falling on the sharp edge of the emitter, is broken by this edge so that vortices appear on both sides. Vortices in the field of their formation cause periodic pressure changes that do not stand still, but propagate through the fluid in the form of ultrasonic waves on both sides of the sharpened plate, as well as inside the Levavasser emitter and towards the body.

The fluid directed by the sharp edge of the Levavasser emitter, together with cavitation vortices arising on the sharp edge with high speed, in the inventive devices of 28 m / s or more, forms a sharp decrease in pressure in zones "C" of the emitters, due to the acceleration of the flow swirling inside the emitter, with the formation of a large number of cavitation bubbles.

Displaced from zone “C” at high speed and under high pressure, due to centrifugal force, the fluid moves to zone “B”, located inside the Levavasser emitters, in which cavitation vortices are destroyed, and a sharply increased pressure compresses the liquid, providing conditions for collapse ( condensation) cavitation bubbles. Moving from zone “B” to zone “A”, the liquid is condensed due to the disappearance of cavitation bubbles and non-faults and flies past the opposite from the sharpened edge at an angle of 90 ° to the leaking liquid from the radiator, interrupting the liquid stream flowing to the edge and contributing to the amplification of ultrasonic cavitation oscillations in a liquid outside the Levavasser emitter.

The constant flow of liquid into the ultrasonic emitter contributes to its whirlpool movement inside the emitter. This movement of fluid inside the emitter during rotation of the rotor, the presence of zones with lowered and high pressure are pronounced unsteady.

The junction surface inside the whistle is not clearly expressed. It is unsteady and fuzzy. Periodically, this surface receives curvatures that progress and turn into separate whirlpools, move to zone “B”, and then “A”, in which liquid breaks and cavitation bubbles disappear with the release of thermal energy, so that they reappear after crossing the flowing liquid upon exiting emitter.

The proposed invention solves the problem: increasing heat production.

The present invention is aimed at achieving a technical result, which consists in increasing the efficiency of heating a liquid by self-pumping a heated liquid.

The specified technical result is achieved by the fact that in a rotary, cavitation vortex pump-heat generator containing a stationary body with a cylindrical cavity and located with a gap in this cavity, a cylindrical rotor, which is rigidly mounted on the drive shaft with the possibility of rotation, a cover, a spacer disk, a suction and discharge holes, on the periphery of the rotor are Levavassera emitters, the sharp edges of which are sharpened at an angle of 30 °.

At the same time, in the pumping section, the suction cavity is connected to the Levavasser emitters by channels, the rotor sections with Levavasser emitters, not equipped with pumping channels, are designed for the second and more stages, the Levavasser emitters are located on the peripheral and inner cylindrical surfaces of the rotor sections.

The rotor can have one section with pumping channels, along the periphery of which are Levavasser ultrasonic emitters and several sections that are equipped only with Levavasser emitters. New is that ultrasonic emitters located on the periphery of the rotor sections, as well as the fact that the pumping channels connect the inlet channel to individual Levavasser emitters. The rotor sections are separated by partitions that isolate the emitters from each other.

Levavasser emitters can be made in the form of round cylindrical, with rods in the center of the emitter, as well as with guide plates - swirlers.

Levavasser emitters can be located not only on the periphery of the rotor sections, but also on the inner surface of the cylindrical part of the rotor.

Rotary, cavitation, vortex pump-heat generator can be performed:

- as in a single-section version, when the rotor consists only of a pumping section, equipped on the periphery with emitters, some of which are connected by channels to the suction cavity of the heat pump;

- and in a multi-sectional version, when the pumping section is mounted on the drive shaft first, and then sections (depending on the required thermal power) are equipped with Levavasser radiators located on the periphery of the section;

- as well as in a multi-stage design, when sections with emitters on the peripheral surface and on the inner cylindrical surface of the rotor are mounted first from the suction cavity, and the pumping section is mounted last.

The placement of Levavasser emitters on the inner cylindrical surface of the sections is due to the need to increase the energy efficiency of heating the liquid by processing it to

revenues in the channels of the pumping section, and then its processing by peripheral emitters.

Technical solutions with features distinguishing the claimed solution from the prototype are not known from publicly available sources of information and do not follow explicitly from the prior art.

- 11 - shows an axonometric section of a multi-section rotary, cavitation, vortex pump-heat generator. The pumping section 12 is mounted first from the suction cavity, and then sections 13 are equipped with Levavasser emitters, but without pumping channels 8;

- Fig - shows an axonometric section of a multi-section rotary, cavitation, vortex pump-heat generator. The first from the suction cavity are mounted sections 14 with emitters located on the peripheral and inner cylindrical surfaces of the rotor 3, the last mounted section 12, equipped with pumping channels 8, all sections are mounted on the drive shaft 15 and enclosed in the housing 1.

The rotary, cavitation, vortex pump-heat generator consists of a stationary housing 1 having a suction and discharge cavities, inside of which one or several sections of the rotor 3 are placed on the drive shaft 15. The housing is closed by a cover 2. The drive shaft together with the rotor sections are driven by an electric motor 4 or another engine. In a single-stage design, the rotary, cavitation, vortex pump-heat generator is equipped with a separation disk 5, in which the suction and discharge windows are located.

The rotor section 3, having on the periphery ultrasonic Levavasser emitters 9 of different tonality or Levavasser emitters with rods in the centers 10, or Levavasser emitters equipped with plate swirlers 11, can be equipped with pumping channels 8 that connect the suction cavity to the emitters, and can be performed without pumping channels.

The rotor section 3 can be made in the form of a blade wheel with emitters in the peripheral part of the blades.

The rotor section 3 can be equipped with Levavasser emitters 9 located on both peripheral and internal cylindrical surfaces.

With a multi-stage design of a rotary, cavitation, vortex pump-heat generator, there can be two options:

- (option 1) on the drive shaft is a section 12 with pumping channels 8, and behind it several sections 13 without pumping channels;

- (option 2) on the drive shaft 15 are placed sections 14 having emitters on the peripheral and internal surfaces, and at the end - pumping section 12.

Rotary, cavitation, vortex pump-heat generator works as follows:

A) one-stage option.

The fluid through the suction hole 6 through the suction window in the dividing wall 5 enters the suction cavity of the rotor 3. After turning on the motor 4, the torque is transmitted through the drive shaft 15 to the pumping section of the rotor 3, placed between the housing 1 and the cover 2. Under the action of centrifugal force, the liquid channels 8 are sent to the emitters of Levavasser 9 and, having filled the entire space between the housing, the rotor and the cover through the discharge hole 7, is sent to the liquid heating system.

During rotation of the rotor section 3, the sharp edges of the Levavasser emitter run onto the fluid at a speed of 28 m / s, they form a “wedge tone” that forms vortices diverging in two directions, some go into the fluid between the rotor section and the housing 1, others are directed inside the emitter. The fluid flow swirling at high speed forms three zones inside the emitter:

- zone of reduced pressure - C;

- high pressure zone - B;

- liquid mixing zone - A.

Passing through zone C, cavitation bubbles and caverns are formed in the liquid, which disappear and “collapse” in zone B.

Moving from zone B to zone A, the liquid is condensed due to the disappearance of cavitation cavities, bubbles and discontinuities and flies past the opposite from the sharpened edge of the emitter, at an angle of 90 ° to the edge of the fluid, flows out of the emitter, interrupting the liquid stream and contributing to the amplification of ultrasonic cavitation oscillations in the fluid between the rotor and the housing. With the "collapse" - the disappearance of the cavitation bubble, temperatures arise up to 2000 ° C and pressures up to 25000 kg / cm ² . This is the main factor ensuring the heating of the liquid.

B) Multistage option.

A multistage rotary, cavitation, vortex pump-heat generator operates as follows:

When rotating through the drive shaft 15 of the pumping section 12 and non-pumping sections 13, the heating of the liquid is carried out in the following sequence. The liquid through the suction cavity of the pumping section 12 is forced into the space between the sections of the rotor 12, 13 and the housing 1. As you move in the space between the sections of the rotor and the housing, the liquid is repeatedly captured by the sharp edges of the emitters, repeatedly processed in the emitters, and reaching the last non-pumping through the injection hole goes to the heating system.

The implementation of heating fluid in a single-stage heat pump with rods in the center of the emitters and without rods is checked in actual examples.

The test results show that both designs of Levavasser emitters are efficient and economical and can be used for heating liquids.

The design of a rotary, cavitation, vortex pump-heat generator is quite simple and can be made at any engineering enterprise.
