Abstract

The present invention describes a method and apparatus to use the kinetic energy available in a liquid flow to produce hydrodynamic cavitation, which, in turn, drives the hydrosonic cavitation simultaneously with sufficient efficiency and capacity to transfer the entire energy of the flow to the liquid as heat and/or another cavitation effect, thus producing physical and chemicals reactions at the molecular and atomic level.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates generally to the formation and collapse of bubbles in hydrodynamic and hydrosonic cavitation phenomena so that the high pressures and temperatures are achieved in these bubbles collapse can be used for heating and/or to trigger and/or enhances physico-chemical transformations in liquid medium.
2. Description of the Related Art
The phenomenon said cavitation that occurs in liquid medium is the formations, growth and collapse of gaseous and vapor bubbles due to the reduction of surrounding pressure below the vapor pressure of the liquid at working temperature. The most widely used techniques to do that are: the generation of sound or pressure waves in the liquid using a piezoelectric transducer, said hydrosonic cavitation, and by reducing the surrounding pressure by the acceleration of a liquid flow through a Venturi tube or a orifice plate, said hydrodynamic cavitation.
Hydrosonics method produces cavitation by generating sound or pressure waves in the liquid medium, so that vapor bubbles are created and growing during the low pressure phases of these waves and are collapsed in the high pressure cycle of the same; these waves can be driving by mechanical means or, mainly, by electrical pulses from a electronic circuit whose energy is transmitted to the static liquid contained in reservoirs through electromagnetic or piezoelectric transducers that can provide an energy transferring near to 85% of the employed sound energy; the efficiency is increased still more when it is running in resonant mode in a small volume reservoir and in ultrasonic frequencies so that the waves are reflected by the reservoir walls and can reach the entire volume of the liquid; each microbubble imploding emits a new shock wave, forming a chain of cavitation in a static liquid this way forming spherical microbubbles, which increases the strength of implosions. These configurations are widely used to objects cleaning, in the chemical and food industry and in the pharmaceutical and laboratory practice. Its efficiency decreases when applied to larger volumes or in moving fluids.
Hydrodynamic cavitation is the physical phenomenon produced in a liquid flow obtained by rapid acceleration of the liquid in a Venturi tube, sharp edges or narrow holes, so that, according to the Bernoulli principle, occurs a drastic pressure fall that reduces the same below the vapor pressure of the liquid medium, so that vapor microbubbles are created and shortly thereafter they implodes when the speed decreases and pressure rises in the Venturi tube output. The hydrodynamic cavitation yield is a little lower than obtained in hydrosonic cavitation because the fast moving fluid disperses randomly the reflection of pressure waves emitted by microbubbles implosions. Therefore, the advantages of hydrosonic cavitation disappear when used in dynamic flows where hydrodynamic cavitation offers most practical and efficient results. This method is used for treating relatively large volumes of liquid as in water treatment and heating, in some specific processes in the food and chemical industry, due its effectiveness and efficiency compared to other methods to do the same.
There are several patents describing both hydrosonic and hydrodynamic cavitation apparatus for various purposes. Hydrosonic cavitation devices using piezoelectric transducers are limited to small static volumes of liquids; another hydrosonic apparatus of reasonable efficiency that can process larger volumes of liquid when powered by electric motor is disclosed in U.S. Pat. No. 5,188,090 as a cylindrical rotor with several peripheral holes which rotates within a concentric housing being supported by bearings and sealed by mechanical seals; It is difficult to build, expensive and needs a pump to force liquid to pass through said housing; both the vibration produced by shock waves as the uneven erosion of the rotor caused by cavitation causes premature damages and incapacitation of rotor, bearings and mechanical seals. Such are also the U.S. Pat. Nos. 5,957,122; 6,595,759; 7,089,886; 6,910,448; and 6,976,486, all with similar rotors endowed with cavities; there are still a device described in U.S. Pat. No. 7,767,159 where the rotor interacts with a concentric stator, both equipped with peripheral holes that is capable, when rotates, to cut and to allow the passage of pressurized fluid at high frequencies given by product of the holes number multiplied by the number of rotations, generating sound waves pulses upstream and downstream in liquid flow, which are, actually, sequences of low amplitude water hammers; this device has the same problems attributed to the U.S. Pat. No. 5,188,090. The Brazilian patent application titled “cavitation and shock waves generator”, produces similar effect but at lower frequency and greater amplitude pulses and need only be driven by a pressurized liquid stream; it is mainly intended to micro-organisms mechanical destruction; Also well known are devices capable of generating hydrodynamic cavitation by forced passage of fluid through plates with small holes; they produces low yield and are susceptible to plugging and erosion by cavitation. There are even systems that use liquid vortices, whose central low pressure generates the microbubbles and the high periphery pressure causes they collapse, that we can see in Russian patent RU 2015715 and in the Brazilian patent application titled “Hydrodynamic Cavitation Generator Device”. The Russian patent is a simple version of Hilsh-Rankine vortex tube on enlarged scale and, like this, has modest energy efficiency; the Brazilian application is restricted to liquids free of solid particles and need a filter to avoid clogging like most hydrodynamic cavitation generators; another example is the application publication US 20070189114 of fairly complex construction.
All forms of cavitation above referred aims heating liquids, especially water, or physical and chemical transformations as the homogenization, the emulsion, the gas dissolution, the degassing and the decanting of solid particles, the enhancement of catalysts and the acceleration of chemical reactions such as esterification and transesterification, particularly in biodiesel production processes; purification and sterilization of liquids, especially water, destroying micro-organisms such as microalgae, bacteria, viruses and fungi, both mechanically, through the impact of shock waves, which cause cell disruption and cavitation induced inside living cells, as by oxidation, provided by reactive radicals such as hydroxyl and hydrogen peroxide, which are produced during the cavitation processes. There are several claims that these devices release more heat than the corresponding energy they consume.
When referring to heating liquids generally we rely only on heating processes based on the fossil fuels, biofuels and on the electric heaters, all with proven energy conversion efficiency slightly above or below 90%. Also are widely known processes and devices for heating water and other liquids that use solar or thermonuclear energy. There are still widely used devices that allows for some power saving capturing thermal energy contained in the atmosphere: the condensation heaters that burn gas or liquid fuel which typically obtained average yield of 114%, incorporating an average of 18% by vapor condensation contained in the atmospheric air, which are used, still now, only in colder latitudes;
Another well-known process, widely used in swimming pools are the “heat pumps”, which are, actually, heat exchanger devices with reverse cooling circuit (Carnot cycle), so that they can absorb the heat energy of the air transferring it to water or other liquid means; manufacturers claim a COP (coefficient of performance) about 250% or more in relation to consumed energy for these devices. The advantage disappear in that the air temperature decreases and/or temperature of the liquid increases, until achieving economically disadvantageous values; as thermal energy production generally exceed the consumed energy, the adopted reference unit is the COP—coefficient of performance—a ratio of total heat produced by consumed energy.

SUMMARY OF THE INVENTION

The present invention discloses a method and apparatus which can heat, directly or via a heat exchanger, water or others liquids and even the environment with a thermodynamic efficiency of COP (coefficient of performance) greater than 2, or more than 200% regarding the power supplied to the input device; furthermore it can perform the other actions assigned to the liquid cavitation phenomena and described above with the same efficiency, and, especially, not conditioned to environmental temperature and air relative humidity, being able to reach temperatures above 150° C. when working in closed and pressurized circuit to prevent the change to the vapor phase in the working fluid.
The present cavitation generator does not go against the energy conservation law: it only retrieves the kinetic energy of a liquid flow as friction heat and sum the amount of the well known energies produced in a cavitation process by dissociation and ionization of molecules of steam while microbubbles implosion inside the liquid volume; furthermore, it also incorporates the energy emitted by chemical micro reactions as the micro combustion that occurs at microbubbles implosion being triggered by pressures above 1000 BAR and temperatures greater than 5.000° K. This generator can be powered by any liquid flow sustaining a heat production proportional to pressure of working liquid. It can pressurized by virtually any type of pump, moved by combustion or electric motors and, directly, by a wind device and even by manual operation, in special cases, such as for emergency water purifiers.
The present invention can also be used to prevent formation of mineral deposits and encrustations in pipes, water tanks, boilers and other hydraulic facilities; it can also be used efficiently to processing liquid foods, enzyme deactivation and protein harvesting. This invention obtains the results above mentioned, according to the testing of prototypes, due to its capacity to generate hydrosonic cavitation within a resonance chamber where a laminar flow moves slowly; powered only by a turbulent flow of hydrodynamic cavitation, so that triggering the generation of large amplitude waves, that produces pressure fluctuations in the laminar flow 4 times, approximately, more efficiently than those generated by piezoelectric transducers. This hydrodynamic cavitation generator produces high density microbubbles clouds due to its ability to fractionate the liquid flow radially dispersing it in a very thin layer of high speed, whose thickness can be regulated externally, according to the pressure and flow characteristics, the density and the viscosity of the liquid. A thin disk limits the radial thickness of the venturi where the liquid is accelerated so that, when the liquid speed is increased, the pressure decreases (in accordance with the Bernoulli principle), and said thin disk is pushed backward forcibly by the greater pressure of the downstream flow; with decreasing of slot passage, the upstream pressure instantaneously increases and push said disc to its initial position; the disc is holding by elastic elements with a limited course, so that allows a vibratory movement can be established; the disk acceleration is proportional to pressure of flow and the disk area and, inversely proportional to the mass thereof. As the forces acting on the disc easily reach tens of kilograms-force to the small mass of the disk, the acceleration module is quite significant, establishing frequencies that will depend on the compression constant of the elastic elements, so that allows easily and precise adjusting. The vibratory motion of said disk defines a fluctuation of speed and pressure which the liquid flows through the gap so that produces also oscillations in pressure upstream and downstream of said disk, as pressure waves; simultaneously hydrodynamic cavitation is generated in the slot passage, where a smaller number of larger diameter microbubbles are produced at higher flow speed, and, a larger amount of microbubbles with smaller diameter is generated at lower speed thereof The amplitude of disk movement can vary from a few thousandths of a millimeter to over 1 mm; its frequency depend on the density, the viscosity and the pressure of working liquid, the pressure imparted to the elastic elements and disk mass and can be adjusted from the audible range until hundreds of kHz. The vibrating motion of said disk allows the use of very narrow slots without causing clogging and without needing fine filters that induce energy waste by load loss, so that can produces a greater cloud of cavitation microbubbles without occurrence of “vena contracta”, common phenomenon that occurs in the “plate of orifices” cavitation devices; in addition, the amount of energy that would be dissipated as vibration and noise is harnessed as useful energy by conversion of vibration in a resonant pressure waves field within a cylindrical chamber, said resonance chamber, wherein a laminar flow of liquid moves slowly; these waves produce high pressure fluctuation, so that said resonating chamber behaves as a ultrasound system, where a cloud of quasi-spherical microbubbles is created at low-pressure phase and collapses at the high pressure peak of every wave; both the vibration frequency and the exposure time of liquid flow to pressure waves are externally adjustable.

a cylindrical rod able to be turned by a handling wheel ( ), said pressure regulating rod (28) provided with a screw portion (29) so that it can screwed into the nut ( ) located in said central bore (4) located at the bottom of said high pressure chamber (1); the opposite end of said rod is endowed with a conical lug, said flow diffuser (30) whose flat base supports a screw (31) with a nut (32) or other means of fastening (33) that are able to support springs and/or other elastic means such as elastomer discs (34) between which said working diaphragm (35).
a thin disc, said diaphragm (35) having a diameter equal to or larger than the diameter of said semicircular cross section bulge (11), which is positioned concentrically and close to the latter, so as to form a circular narrow slot (36) with venturi-shaped cross-section; said diaphragm (35) is provided with a central hole (37) in which fits the screw of said flow divider (28) of said pressure regulating rod (28) and which is limited on both sides by springs (32), elastomer discs (33) or other elastic means, that are retained by a nut (32) that can adjust the pressure of these elastic means against the base of said flow divider (30), so that said diaphragm (35) may establish a resonant vibratory motion; said pressure regulating rod (28) can adjust, thus, the pressure of the entire assembly and, therefore, the vibration frequency of said diaphragm (35);

a liquid retainer (40) or other sealing member positioned around said flow regulation rod (20) fitted in housing (41) on the bottom of said collecting chamber (23) to preventing leakages;
two manipulating wheels (42) or other manual facilitators means fixed on the outer edges of the pressure regulating rod (28) and of the flow regulation rod (20), (4:26) whose screw portions (21, 29) also receives nuts (43) to hold these rods in selected positions.
gaskets (44) are used to prevent leakage, which are interspersed between the flanges of said high pressure chamber (1), said annular divider (8), said semi toroidal disc (13) and said collecting chamber, which are strongly attached by sets of screws (45) and nuts (46) distributed in the holes (47) on the flanges which are coincident with each other.
Said diaphragm (35) is a thin disk so that its mass is reduced sufficiently to allow to achieves high frequencies, but at the same time it should withstand relatively significant deforming forces; to allowing ultrasonic frequencies operation, it must be built on sturdy and inox materials; FIGS. 5, 6 and 7 shows constructive variations that add resistance's shape and, at the same time, generates waveforms that increase the nodal intersections between the primary fronts and the reflected ones at the bottom of said resonance chamber; FIG. 8 shows a disc with several small holes (48), an artifice to be used to decrease the mass of said diaphragms and, at the same time, to produce additional cavitation.
The operation of present hydrodynamic and hypersonic cavitation generator starts when water or other working liquid is introduced into said high pressure chamber, where it is immediately directed to the interior of said vortex tube through the lateral openings tangentially directed, undergoing angular acceleration and assuming spiral movement around the said pressure regulating rod; on reaching said flow diffuser the liquid is directed radially outward, passing through the venturi like narrow slot, where it undergoes strong acceleration and and thus, a drastically reducing of pressure; this high depression produces a lot of vapor bubbles and causes said diaphragm to be pushed against the bulge of said annular divider, abruptly decreasing flow passage area of said slot, but without closing it completely due to an instantaneous pressure increasing at upstream; the flow speed and the depression further rises due to upstream pressure growth, but, the increasing pressure exceeds all the others owing to inertial force like a partial water-hammer, until a reversing point when said diaphragm is violently pushed in opposite direction; as said diaphragm is restrained on both sides by elastic members, a resonant oscillatory motion is established in accordance with: f=(P·A·t)/(I·m), where f is the frequency, P, the flow pressure, A, the area of the diaphragm, t the time, I, the diaphragm free course and m, the mass thereof;
The vibratory movement is transmitted to the volume of liquid, downstream of said diaphragm, in waves form with the net power defined by: I=(P×Q)/(A×k), where I is the power in W/cm², P is the pressure in kgf/cm², Q the rate of the flow in liters per minute, A is the diaphragm area and k, the constant (=0.6); on this basis it easily reaches ultrasonic frequencies.
the liquid oscillating pressure in the flow passage at the narrowest point of the annular venturi is always lower than the point of vapor of the liquid, due the fluctuation of speed, which produces a dense cloud of diverse sized cavitation microbubbles; as the flow is driven radially within the narrow opening of the venturi, its velocity falls exponentially and, the opposite, occurs with the pressure, which causes the collapse of microbubbles in a very short time; said toroidal cavity around the circular slot edges creates an internal toroidal vortex, whose peripheral centrifugal pressure collapses all microbubbles and creates a protective barrier which prevents erosion of the chamber inner walls; from there, the flow is directed into said resonance chamber (1), whose diameter is substantially greater than the inlet pipe, forcing the fluid to moves in slowly in a laminar flow, so that it remains overtime exposed to pressure wave column generated by said diaphragm liquid speed within said resonance chamber produces a Doppler effect on the pressure waves field so that, even in a resonant mode, the waves that move away from said diaphragm have a longer length than the reflected ones, mainly in relation to the moving liquid volume, this way producing also a great variety of microbubbles sizes; the liquid path leads it into said collecting chamber, where the liquid absorbs the sound and vibrations produced by said resonance chamber walls and then, is forced out through said outlet tube. The microbubbles generated by waves means, both infrasound as ultrasound, are generally spherical and implode with the energy: E=4/3·pi·R³·P where R is the radius of the microbubbles and P, the peak pressure of the pressure waves.
For water heating in vessels (FIG. 9) as swimming pools and spas and even domestic boilers (49), which operate at lower than 50° C. temperature, the liquid is drawn from the tank (49) by pump (50), injected directly into the present generator (51) and returned to the tank (49); this configuration can also be adopted for sterilization of liquids, acceleration of chemical reactions, emulsification, biodiesel production and others processes that needs the effects of intense cavitation. For said passage heating usage, it is necessary a “bypass” (52) system and control valves (53) to regulating the amount of liquid that must be reprocessed and that one which is can released at a desired temperature according to the power of the installed pump (FIG. 10); the present generator also can produces heat for boilers, in addition to water's point of vapor at ambient pressure, since the liquid phase is maintained by a pressurized system, which, as shown in FIG. 11, need a safety valve (54). For heating other liquids as foods, chemicals or, for environmental heating, a heat exchanger (55) must be associated with as shown in FIG. 12; this circuit must have a gas bleeder (56) endowed with a safety valve (54), necessarily.
