DETAILED DESCRIPTION
[0032] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They do not intend as an exhaustive description of the invention or do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.
[0033] The present invention, in one exemplary embodiment, is a system and method for using micro arc processing in a rotating magnetic field for high purification of urban domestic and industrial wastewater and sewage sludge with minimum energy consumption. It can also be the basis for the construction of sewage treatment systems of inhabited locality used local and centralized sewerage (sanatoriums, hospitals, schools, hotels, offices and shopping complexes), as well as treatment facilities of any type industrial enterprises, including food and light industry, processing of agricultural products, industrial livestock farms, poultry farms, etc.
[0034] Referring initially to the drawings,
[0035] As illustrated in
[0036] The tubular reactor 102 further comprises control and thermal protection units, a frequency regulator of the supplied current from approximately 50 to 100 Hz, a power regulator installed in front of the inductor 140 in the range from approximately 5 to 100 kW with a continuous mode of its change, and a contactless phase switch with a switching frequency of approximately 50 to 100 periods per second. The tubular reactor 102 further comprises a power source 128 and a power regulator 130. The power regulator 130 is in electrical communication with the inductor 140. The tubular reactor 102 further comprises a reactor cooling component. The reactor cooling component is configured to cool the inductor 140. The reactor cooling component comprises a plurality of inlet pipes 122, a plurality of outlet pipes 124, and a plurality of fins 126 for containing a water-based or oil-based coolant. The tubular reactor can operate at a range of approximately five to 100 Kilowatts or higher.
[0037] The inductor 140 comprises a body 142, a magnetic core cassette 144, a magnetic circuit 146 and a winding 148. A core of the transformer of the inductor 140 may be laminated from electrical steel. The winding 148 is configured to generate the rotating electromagnetic field within the tubular working chamber 150 uniformly distributed and perpendicular to its axis. The winding 148 may be a symmetrical reduced two-layer loop, wire with oil-resistant insulation and operating temperature up to approximately to 200 degrees Celsius. Alternatively, the winding 148 may be constructed of wire with waterproof insulation with an operating temperature of up to approximately 90 degrees Celsius.
[0038]
[0039] The plurality of ferromagnetic elements 160 (hereinafter—“indenters”), are positional within the cylindrical working zone 156 of the non-magnetic tubular working chamber 150 that does not interact with the field. The plurality of ferromagnetic elements 160 are generally needle-shaped and configured to kinetically interact with the waste material when triggered by the rotating magnetic field generated by the inductor 140 as illustrated in
[0040] As illustrated in
[0041] During their movement, the indenters continuously create micro arcs and power micro impulses, which in direct contact virtually no materials cannot withstand. The simultaneous influence of all these factors allows translating all processes in the working area 156 of the tubular reactor 102 into a kinetic mode, which in contrast to diffusion, inherent in all traditional processes, and, accordingly, dramatically increase the productivity of materials and media, increase the reaction rate, etc.
[0042] Under conditions of a strong electromagnetic field, powerful currents arise in the working bodies, leading to the formation of micro arcs when the micro circuits break during the rotational movement of the needles 160. Under the influence of the rotating magnetic field, the ferromagnetic elements 160 rotate with an accompanying change in polarity. With this magnetization reversal, there is a very rapid change in the discharge positions, entailing a rapid change in the linear size of the needles 160. As a result of these almost continuously emitted power impulses, a large force is applied to the environment (approximately 15 to 20 tons/mm2), acting over a small distance. In water, the extent or range of interaction of these pulses is several times larger than in solid-phase operations. When performing, the ferromagnetic elements 160 that fill the working chamber 156 gradually wear out, and the efficiency of the treatment process of necessary substances is reduced. Therefore, new indenters 160 are periodically supplied to the working chamber 156 by the dosing system 100, filling it with integral elements instead of the used ones. The indicator of filling of the working chamber 156 is the change of current of the phase winding 148 of the inductor 140, which is fixed by the devices and used by an automatic control system or operator.
[0043] When moving, the ferromagnetic working elements 160 continuously emit powerful local micro-impulses and micro-arcs (hereinafter “MIPMAP”). This action facilitates the intensive dispersion of any solid materials, as well as the mixing of the treated medium. Several effects are generated that combine with the local thermal and mechanical phenomena that occur when the ferromagnetic working elements 160 interact with a substance. The power of these effects is so great that, acting simultaneously on any particles of a substance, they provide structural and energy changes at the molecular and atomic level.
[0044] As a result of these interactions the wastewater to be treated is exposed to the following effects: particle dispersion; water ionization with separation of H+ and Hydroxyl Group OH−; weakening of intermolecular and interatomic bonds; oxidation/Reduction reactions (redox) by free radicals; magnetic field sustaining processes with highly ionized entities; magneto Hydrodynamic shocks comparable to cavitation processes or hydro-acoustic effects; intensive mixing; and localized thermal effects. The combined effect of all factors creates a very high level of activation of all components of the substance involved in the process. The reactions are no longer diffusion controlled but become a function of the discharge phenomena with associated increases in the rates of change or reaction kinetics. This process enables a rate increase in the treatment process by many orders of magnitude thereby reducing energy use and achieving processes previously considered unattainable.
[0045] The subject matter disclosed and claimed herein, in another embodiment thereof as illustrated in
[0046] As discussed supra, the tubular reactor 102 comprises the tubular chamber 150 and the inductor 140. The tubular chamber 150 comprises the nonreactive shell 154 and the cylindrical working zone 156 encapsulated by the shell 154. The inductor 140 comprises the winding 148. The winding 148 is configured to generate the rotating electromagnetic field around the tubular working chamber 150. The plurality of ferromagnetic elements 160 are positional within the cylindrical working area 156 of the tubular working chamber 150. The plurality of ferromagnetic elements 160 are needle-shaped and configured to kinetically interact with the waste material when activated by the rotating magnetic field generated by the inductor 140. The ferromagnetic needle elements 160 may have a diameter of 0.5-1 mm and a length of 8-12 to intensify the mixing of liquid media, or liquid with gaseous media (including the formation of micro- (nanosized) bubbles), and also to increase the degree of solubility of miscible media (including gaseous media in liquids). Alternatively, the ferromagnetic needle elements 160 may have a diameter of 1-1.6 mm and a length of 12-20 mm to intensify the mixing of liquid media with solid particles with simultaneous dispersion (grinding) of these solid particles (including to obtain suspensions), as well as to intensify the mixing of liquid media, which are not prone to mixing and dissolving with each other, and to obtain emulsions. Alternatively, the ferromagnetic needle elements 160 may have a diameter of 1.6-3.2 mm and a length of 20-40 mm for intensification of dispersion (grinding) and mixing of solid materials, as well as for mixing (grinding) of liquid and semi-liquid materials (media) with increased values kinematic of viscosity greater than 0.155 in.sup.2/s (100 mm.sup.2/s). The ratio m/V of the mass of the ferromagnetic needle elements (m in grams) to the volume of the working area of the tubular reactor (V in cm.sup.3) may be selected from the range: m/V=0.1-0.4 g/cm.sup.3.
[0047] The activated plurality of ferromagnetic elements 160 generate the micro arcs and power micro impulses that kinetically treats the waste material. Depending on the waste material to be treated, the plurality of ferromagnetic elements 160 may be coated with a catalytic metal or an elastic polymer shell.
[0048] The method 200 continues at 230 by separating the treated waste material into usable component materials which comprises subsequent separation of the obtained fractions (products) after treatment of waste in a rotating electromagnetic field using microarcs and power micro pulses. The method 200 may further comprises retreating at least a portion of the treated waste material with the system 100 for treating waste material at 240. Once retreated, the retreated waste material is separated into usable component materials at 250.
[0049] The processes in the reactor can be enhanced by the addition of chemical additives comprising sources of hydrogen and hydroxide ions that can become reactive entities in the reaction zone such as the formation of superoxide and super hydrogen ions and other energized species. These reagents are not limited to hydrogen and hydroxide entities but can include other chemicals gases, liquids and solids that decompose or react to form energized entities in the reaction zone of the MIPMAP reactor.
[0050] This unique combination of processes leads to accelerated chemical and physical interactions with rapid kinetics for the treatment processes. These are of both macro-duration and micro-duration. The outcomes from these complex reactions are that complex solids are formed with oxidation of heavy metals and removal of organic materials either through polymerization, breakdown, or adsorption. As illustrated in an example of a study on the wastewater treatment of fish processing enterprises shown in

[0057] Among the benefits and advantages of the innovative technology of the present invention is the possibility of complete sewage utilization to get commercial products, including purified water, organic fertilizers, purified fine sand, and metal concentrates. Biological treatment systems do not achieve complete cycle of sewage disposal, as there is a need of additional disposal of sludge, including its disinfection and dehydration. At the same time, there is a problem of cleaning heavy metals from the sludge which cannot be solved on site in most cases. A very important advantage of the innovative technology is the dispensing of the necessity for sludge beds. These can occupy tens and hundreds of acres in large biological treatment plants and can cause extensive damage to ecology. In addition, the equipment for microarc processing in rotating magnetic fields differs from conventional technology by using significantly lower materials intensity and lower power intensity for the purification process.
[0058] Notwithstanding the forgoing, the system 100 can be any suitable size, shape, and configuration as is known in the art without affecting the overall concept of the invention, provided that it accomplishes the above stated objectives. One of ordinary skill in the art will appreciate that the shape and size of the system 100 and its various components, as show in the FIGS. are for illustrative purposes only, and that many other shapes and sizes of the system 100 are well within the scope of the present disclosure. Although dimensions of the system 100 and its components (i.e., length, width, and height) are important design parameters for good performance, the system 100 and its various components may be any shape or size that ensures optimal performance during use and/or that suits user need and/or preference. As such, the system 100 may be comprised of sizing/shaping that is appropriate and specific in regard to whatever the system 100 is designed to be applied.
[0059] What has been described above includes examples of the claimed subject matter. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the claimed subject matter, but one of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Accordingly, the claimed subject matter is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims.
