Description

DEVICE FOR GENERATING SINGLE OXYGEN BY MAGNETIC FIELD ACTION FOR IN SITU OXIDATION/DEGRADATION OF COMPLEX CHEMICAL SYSTEMS

FIELD OF THE INVENTION

[01 ] The present invention fits into the field of process, chemical, mechanical and environmental engineering, particularly in equipment, devices or machines for generating singlet oxygen from air with subsequent application of ultra violet radiation (UV) to generate a highly oxidizing environment favorable for the formation of other reactive oxygen species and capable of promoting the oxidation/degradation of several classes of complex organic compounds, harmful to the population and the environment, present in liquid, solid and gaseous states. [02] The technological field of the invention relates to equipment capable of generating air with high oxidizing power, that is, highly reactive, consisting of singlet oxygen generated by the action of a magnetic field, capable of oxidizing complex and recalcitrant organic compounds in the presence of UV radiation, which allows the formation of a range of reactive oxygen species, and which enhances the oxidation/degradation of electron-rich compounds such as amines, phenols, sulfides, among others.

FIELD OF USE

• Oxidation water treatment for swimming pools, lakes, aquariums, rivers, etc.;

• Treatment of landfill leachate;

• Treatment of gases resulting from burning, incineration and other combustion processes of organic compounds, eliminating dioxins, furans, nox, CO2 and other harmful gases;

• Catalysis of diesel engine combustion gases by replacing the air with a urea solution that is used in stationary engines; of ships, automobiles and vessels in general;

• Air purification, especially in hospitals, clean surgery rooms, nursing homes, daycare centers and homes, shopping malls, commercial establishments in general, eliminating viruses, bacteria, mites, fungi, etc.; • Oxidation of organic matter in industrial processes.

[03] According to the invention, the equipment consists of two chambers connected to each other; the first chamber being composed of concentric tubes into which, through the internal tube, atmospheric air enters and passes through a particulate matter retention filter. The internal tube has a symmetrical arrangement of holes, and in each of these holes, there is a device composed of a diffuser and two magnets with high magnetic power facing each other, with the purpose of producing a magnetic field capable of acting in the production of singlet oxygen from the air passing through this device. The air with a proportion of singlet oxygen (air with high oxidizing power) passes to the external tube/casing of the first chamber to be displaced to an arrangement of converging pipes that communicate with the second chamber, which is surrounded by UV radiation generated by a series of lamps arranged in a given geometric arrangement that allows uniform radiation of the chamber.

BACKGROUND OF THE INVENTION

[04] Oxygen in its stable state appears as triplet oxygen and one of its unstable forms is singlet oxygen. The unstable form occurs when its electrons at the most energetic level are unpaired and for this there are two reasons, either because the electrons have the same orientation or because there is only one electron in the orbital. Therefore, one of the possible ways to change oxygen from its triplet state to the unstable and reactive state (singlet) can be by subjecting the oxygen to a magnetic field, for this it is important to highlight that oxygen has paramagnetic properties, which means that it undergoes action of a magnetic field.

[05] Oxygen in its state as singlet oxygen increases its reactivity by 1500 times, making it more reactive than several do other oxidizing agents such as ozone make. In a table that evaluates the oxidation potential of species, singlet oxygen has a value of 2.42 volts, while species considered highly oxidizing such as ozone (2.07 volts), hydrogen peroxide (1.77 volts) and hypochlorite (1.49 volts). The high oxidizing power makes it a great candidate to be used for the oxidation of complex organic and inorganic substances. Despite being highly oxidizing, the lifetime of singlet oxygen can be very short, depending on the environment in which it is found (example water 4ms and chloroform 250ms), therefore requiring its immediate consumption.

[06] Based on the previous description, the present invention shows an equipment designed to generate highly oxidizing air composed of singlet oxygen obtained by the action of a magnetic field caused by high-performance magnets, associated with a reactive chamber containing UV radiation to maximize the presence of reactive oxygen species, enhancing the degradation/oxidation capacity of complex organic substances present in liquid, solid and gaseous media.

[07] A prior analysis of the state of the art reveals equipment for the treatment of organic substances using pyrolysis technology as in a Japanese patent JP2010058103, which presents ecological pyrolysis equipment for organic substances. In this device, there is a magnet in the air inlet to minimize the amount of air needed.

[08] Another development of the prior art is illustrated in a Japanese patent JP2011 131127, it includes equipment and method for decomposing chemical substances such as PCBs and dioxins. This equipment mixes the ground material of residual organic matter with the chemical substance and is exposed to previously generate magnetic air.

[09] PCT Patent W02008040159 describes waste decomposition equipment using magnetic energy, where the magnetic energy converter is a rod made of fire-resistant material and a magnetic ring inserted into this rod, which has a central input that connects to the inside and outside of the decomposition box. The invention highlights the natural way of regulating magnetic energy and oxygen concentration. The invention can control the intensity of the magnetic field entering the decomposition box, and can more effectively decompose and adjust the decomposition of plastics of different types; in addition, it allows controlling the intensity of the magnetic field in different regions, resulting in better results.

[010] Another technology observed is in the PCT patent document WO201 4092091 , which illustrates a magnetic pyrolysis device, comprising a first air distribution tube that is disposed on a peripheral wall that extends to the lower section of an organic material housing space and which caused the air to flow from the side of the lower section to the organic matter accommodation space, and the air passes through a permanent magnet that is attached to the first distribution tube and that magnetizes the air; and an escape mechanism comprising a gas exhaust pipe extending from the decomposition furnace to the exterior, into a blower that discharges the gas force that is generated in the organic matter housing space during the pyrolysis of organic waste material.

[01 1 ] The prior art also reveals another Chinese patent, CN1 1 1853807, which aims to provide a low-temperature magnetization cracking device with a surrounding layer of magnetic ash, which has the advantage of shielding the magnetic waves from the magnetized air forced into of a cavity.

[012] Another prior art application is a Brazilian patent BR1020120138638 which illustrates a device called a solid organic matter combustor intended for the elimination of solid organic matter, contaminated by pathogenic or non- pathogenic biological materials or by chemicals of a wide range of nature. The object of this patent uses an innovative catalysis resource that consists of passing the flow of process air containing oxygen through a small chamber, placed immediately before each of the process air entry control holes, and in these chambers there are two or more permanent magnets, similar in power to those used in common speakers on the market.

[013] Another proposal described by the state of the art is illustrated in another Brazilian patent BR102013009957, which describes an organic matter decomposer with a gas filtration system where it is necessary to adequately control the amount of oxygen that enters this chamber, to avoid excessive and uncontrolled burning of these organic residues, thus guaranteeing all the necessary properties for this combustion system to produce results that are not harmful to the environment. The supply of oxygen to this system is carried out through small holes located at the base of this combustion chamber, in which two magnetic elements (magnets) are placed in parallel. Oxygen enters the chamber through holes proportionately and appropriately sized for each dimension of the combustion chamber, being arranged at the bottom of the walls that constitute said chambers, where, through controlling the necessary quantity of oxidant, through controlling the quantity and quality of the oxygen available, a complete slow combustion process is established. Slow combustion is characterized by a temperature that does not exceed 500°C.

[014] The prior art also reveals a Korean patent KR102492094, which describes a magnetic thermal decomposition device that performs self-pyrolysis, placing air to which a magnetic field has been applied in contact with the surface of the object to be decomposed. An exhaust pipe for extracting, a filter unit for generating recycled air by purifying the exhaust gas introduced into the exhaust pipe, an inlet pipe for supplying the recycled air to the decomposition-processing unit, and iron connected to the decomposition-processing unit between the inlet pipes. A magnet installed outside the tube to separate the oxygen and nitrogen contained in the recycled air through a magnetic field, and a hydrogen injection unit installed on one side of the decomposition unit to inject a hydrogen gas mixture into the decomposition unit, in order to improve the efficiency of the decomposition/oxidation reaction.

[015] From the above, it is important to highlight that the state of the art shows the use of magnetic air in all the applications presented, it is also verified that the box or device where the air is magnetized is always located inside the general chamber.

[016] There is NO evidence of equipment or devices that allow the coupling and uncoupling of the air generating chamber with high oxidizing power with the oxidation/degradation chamber, nor of devices that increase the contact between the air and the applied magnetic field. Only air intake control devices and the application of the magnetic field were found within the air magnetization chamber. Additionally, a patent that uses the application of hydrogen to accelerate the degradation reaction was found. In this case, it is very different from the alternative for accelerating and catalyzing the oxidation/degradation reaction presented in the equipment covered by this patent, which features a device containing an arrangement of UV lights to improve the oxidizing environment of the reaction chamber.

OBJECT OF THE INVENTION

[017] A first objective of the present invention is to avoid the disadvantages of the prior art. More particularly, an objective of the invention is to create equipment capable of generating highly oxidizing atmospheric air used for in situ oxidation/degradation of complex compounds present in liquid, solid and gaseous states.

DETAILED DESCRIPTION OF THE INVENTION

[019] This invention refers to equipment composed of two chambers, in which in the first chamber air with high oxidizing power is produced from atmospheric air through the application of a magnetic field and in the second chamber air with highly oxidizing power enters in contact with UV radiation and organic matter to be oxidized/degraded, increasing the generation of other free radicals and enhancing the degradation of complex chemical substances.

[020] Figure 1 A illustrates the isometric view and Figure 1 B illustrates the exploded view of the assembled invention, in general the present invention consists of two chambers, chamber A is composed of two concentric tubes, inner tube (3) and housing (4), the outer tube also called housing (4) wider than the inner tube (3). The internal tube (3) of chamber A is coupled to a butterfly valve (2), which is also coupled to a flange (1 ) for its respective connection to a compressor for atmospheric air intake. The inner tube (3) is open at its upper end and closed at its other end with a hyperbolic termination. The external tube (4) of chamber A is coupled to the internal tube (3) at the upper end and at the other end it is coupled to a tube (5) of smaller diameter, which has inside an arrangement of symmetrically distributed convergent nozzles. (1 1 ), this tube (5) at its lower end is coupled to chamber B (6).

[021 ] Chamber B (6) is a tube with a diameter equal to the diameter of the housing (4) of chamber A. Chamber B (6) at its upper end is coupled to the tube (5) which has the arrangement of nozzles convergent (1 1 ) and at its lower end it is closed, additionally chamber B (6) has a valve (7) attached, which allows the fluid to enter in solid, liquid or gaseous state, this valve (7) can be coupled to a compress or a pump depending on the physical state of the complex mixture to be treated. To exit the treated fluid from chamber B (6), a valve (8) is also attached, which can be coupled to a compressor or pump depending on the physical state of the material to be treated. On the inner wall of chamber B (6) there is a set of ultraviolet lamps (12), distributed in a geometric arrangement that can be staggered or aligned in the direction of the fluid velocity, which have the function of accelerating the reaction between the organic matter and air with high oxidizing power.

[022] Figures 1 A to 1 E allow us to describe the process of the present invention, atmospheric air enters through the valve (2) and passes through an air filter (9) which has the function of removing particulate matter from the atmospheric air, which is coupled to the inlet of the internal tube (3) of chamber A. The inner tube

(3) is a smooth tube up to the coupling position with the housing (4) and then is a tube with circular holes in a straight and alternating arrangement.

[023] Atmospheric air without particulate matter enters the tube (3) of chamber A and exits through the straight and alternating arrangement of perforations in the internal tube (3), in each of the perforations mentioned a box containing pairs of magnets is attached. (10) rectangular in shape with a lower base of the tube equal in size to the holes in the internal tube (3) through which the air without particulate matter passes, part of the oxygen contained in the air without particulate matter is converted into air with high oxidizing power at starting from the application of a magnetic field generated by an arrangement of magnets with high magnetic power, as a result of the passage of air free of particulate material through the device containing the magnets (10), air with high oxidizing power is obtained at the exit, this air with High oxidizing power diffuses into the casing (4) of chamber A and is forced to pass through the tube (5) which has the arrangement of converging nozzles (1 1 ) that allows entry to chamber B (6).

[024] The fluid to be treated, which can be a solid, liquid or gas, containing organic matter that is difficult to degrade, enters chamber B (6) through the valve (7) and diffuses inside chamber B (6) . Inside chamber B (6), the fluid that requires treatment comes into contact with air micro particles with high oxidizing power that passed through the magnets and exited through the conical nozzles located at the exit of chamber A. Inside chamber B the reaction of oxidation/degradation of the material of interest occurs catalyzed by the incidence of UV radiation, carried out by an arrangement of UV lamps (12) arranged homogeneously and uniformly in chamber B (6). The presence of UV light in chamber B (6) coupled to chamber A enables greater efficiency in the degradation process of complex chemical species, as it increases the flux density of excited electrons in the system, increasing the probability of formation of other radicals super oxidants, which guarantees better performance in the removal of complex substances. The decontaminated fluid with the recalcitrant organic matter removed is treated through the outlet valve (8) located in the upper final part of chamber B (6).

[025] Figure 2A illustrates an exploded view of the box containing the magnets (10), Figure 2B illustrates a bottom view of the box containing the arrangement of the two magnets (10), Figure 2B illustrates a bottom view of the box containing the arrangement of magnets (10), Figure 2C illustrates a top view of the box containing the arrangement of magnets (10), Figure 2D illustrates a sectional view of the arrangement of magnets and the diffuser inside the box containing in geometric arrangement the two magnets (10) and Figure 2E illustrates a detailed view of the arrangement of the diffuser inside the box containing the magnets (10).

[026] From the set of Figures shown, it is possible to detail the process inside the magnet box (10) present in the invention. The magnet box (10) is composed of a diffuser (13) at the bottom arranged in a circular shape with a radial distribution of holes, which are coupled to each of the holes in the inner tube (3) of chamber A.

[027] The main body of the box (10) is a solid U-shaped profile plate (14) to which in its lower part there is a circular hole where the diffuser (13) is attached, on each side of the profile U-shaped shape (14) in the upper part has two holes where the set of screw, spring washer, nut and washer (19) is positioned, in total 4 sets.

[028] Two hollow U-shaped profile plates (15) with a hole in the upper front part where the screw, pressure washer, nut and washer assembly (18) is located and a hole in the upper sides where the set of screw, spring washer, nut and washer (19) for each side. Inside the hollow plate of the U-shaped profile (15) the U- shaped insulator (16) is located. On the inner front of the U-shaped hollow plates (15). On the inner front of the hollow U-shaped plates (15) there is a set of rectangular magnets with high magnetic power (17). For each box (10), there are two magnets with high magnetic power positioned opposite each other.

[029] The air without particulate matter inside the inner tube 3 of chamber A is displaced through each of the holes, where it passes through the diffuser (13) and diffuses through the box (10) passing through a magnetic field that is generated by the action of the two high magnetic power magnets (17), during the passage of air without particulate material through the magnetic field is where the conversion to air with high oxidizing power with the presence of singlet oxygen takes place. The objective of the diffuser 13 is to reduce the air speed and increase the contact time between the air and the magnetic field, improving the efficiency of the process.

[030] Air with high oxidizing power leaves the magnet box (10) and is diffused through the housing (4) to the tube (5) which has a radial arrangement of converging nozzles (1 1 ). Air with high oxidizing power passes through the arrangement of converging nozzles (1 1 ) increasing the speed and enters chamber B (6). The fluid that contains organic matter that is difficult to remove enters chamber B (6) through the valve (7). In chamber B (6), the oxidation reaction of organic matter occurs with air with high oxidizing power in the presence of UV radiation generated by the arrangement of UV lamps (12), located inside chamber B (6). The purpose of the light is to increase the reaction between organic matter and air with high oxidizing power. Finally, the fluid leaves chamber B (6) through the valve (8)

[031 ] The design for the equipment proposed in the present invention allows chamber A to be decoupled from chamber B, which allows for a greater possibility of applying the equipment for different purposes. The use of only chamber A is suitable for industrial or environmental conditions in which organic matter is confined in another tank, pipe, reservoir or any storage system and this can be coupled to the outlet of tube (5) which has an arrangement of converging nozzles (1 1 ) where air with high oxidizing power exits.

[032] Only some preferred embodiments of the invention have been illustrated by way of example. In this regard, it will be appreciated that the present invention as well as the rotational arrangements can be chosen from a plurality of alternatives without departing from the spirit of the invention according to the following claims.
