Description

Technical Field [0001] The present invention relates to a metal waste-containing oil removal method using a quantum energy generator,

The present invention relates to a metal waste-containing oil removing apparatus using a quantum energy generator, and more particularly, to a metal waste containing metal waste using a quantum energy generator for effectively recycling the metal waste contained in an iron or non- To an oil removing apparatus.

As is well known, it is known that iron and nickel containing oil such as cutting oil generated in lathe turning, milling, grinding, precision particle machining, cutting, , And iron and non-ferrous metal-based materials such as titanium, tin, copper, stainless steel (STS 304,316,403) and carbon steel (S45C) are very valuable resources. However, the current waste law requires metal wastes containing more than 5% Is prohibited from being recycled and disposed of.

In particular, metal waste containing such oil is prohibited from landfilling, and therefore, it is inevitably pyrolyzed or incinerated at high temperatures. However, since cutting oil contains toxic additives such as chlorine, phosphorus and sulfur, And the like, resulting in pollution caused by the pollution.

On the other hand, the process of removing oil from metal waste and recycling it as ferrous metal or non-ferrous metal can significantly reduce the emission of hazardous substances as well as drastically reduce the production cost compared to the process of producing ferrous and nonferrous metals by collecting and smelting minerals In this regard, it is necessary to consider recycling of metal waste containing oil.

To this end, Korean Patent Laid-Open No. 10-2009-0118490 (entitled: chip compressor (hereinafter referred to as "cited invention") has been proposed.

1 and 2, the cited invention is roughly divided into a loading unit 100, a forming unit 200, a press unit 300, an opening and closing unit 400, and a storage unit 500.

A hopper 110 is formed in the loading part 100 to allow a chip generated after a machining operation to be drawn in.

At this time, it is preferable that the hopper 110 is formed in a shape of upper light-tight narrow openings so that the chips can be collected and loaded downward.

When the chip is loaded downward by using the hopper 110, a press-fitting cylinder 130 having a pressing member 120 at the lower end thereof is installed so as to be automatically pressed by a periodic operation, can do.

In this way, the chip inserted by the press-fitting cylinder 130 is first down-compressed.

In this cited invention, first, as shown in Fig. 2, the chip is led through the input unit 100. Fig. The introduced chip is first down-compressed by the pressing member 120 of the press-fitting cylinder 130. The compression cylinder 320 is advanced while the pressurizing cylinder 130 is reciprocating vertically and the shielding tube 410 is moved downward to prevent the press rod 310 from advancing.

Thereafter, as the compression cylinder 320 advances, the chip is compressed by the press rod 310 inside the press housing 210, and at the same time, the cutting oil contained in the chip flows downward through the outflow tube 230.

At this time, the chip is compressed according to its shape in the press housing 310 having a predetermined shape toward the side where the chip is pressed.

In addition, the press-fitting cylinder 130 is in a stationary state while being moved upward, and at the time when the compression of the chip is completed, the opening / closing cylinder 430 moves the shielding member 410 upward.

At this time, if the chip bundle P is further pushed in the stop state of the press rod 310, the chip bundle P may be allowed to fall down freely, or the shielding member 410 may be moved downward again, ) May be pushed downward to be dropped.

The chip bundle P thus dropped is pushed out by the discharging cylinder 520 in the storage part 500 and exits to the outside.

In the case of spiral chips or metal wastes having a large particle diameter, the oil can be removed to some extent, but the grinding process, precision particle processing The dense metal waste discharged from the process is extremely small in particle diameter, resulting in a very low oil removal rate.

In addition, when the fiber material used in the machining process grasps the abrasive and the softening, it is difficult to expect the oil removal by the pressing.

As described above, the conventional crushing facilities including the cited invention can only slightly reduce the oil content of the metal chip, and can not remove the oil content of the metal waste to such an extent that it can be used for materials for manufacturing automobile parts and aircraft parts. , And it is difficult to recycle metal waste.

In particular, when reducing the allowable content of oil in metal wastes from less than 5% to less than 1PPM, titanium alloys can be used as high-value structural solvents and high-performance materials, depending on the material. Iron, aluminum, magnesium, stainless steel, Since there is an enormous demand for aircraft material and ship material, effective metal waste oil removal technology that can greatly reduce the oil content of metal waste is urgently required.

FIG. 3 shows the overall steps of the method for removing metal waste containing oil using the quantum energy generator according to the present invention.

As can be seen from the above description, the present invention firstly involves immersing iron and non-ferrous metal waste (hereinafter referred to as "metal scrap") containing oil in a cage composed of a mesh and frame of a certain volume for a predetermined period of time After the primary oil is removed, the cage is lifted with a crane lifting device and a pretreatment step is carried out using a washing tank that recovers the solvent contained in ferrous metals and non-ferrous metals by gravity.

In the present invention, an alkaline solution is supplied for degreasing, an electric current is supplied to the scrap of iron and nonferrous metal to be degreased to increase the degreasing effect by electrolysis, and the active gas is mixed with the degreasing solution which has been subjected to the water- Then, a quantitative energy is irradiated to the metal scrap and the metal scrap is sprayed to the metal scrap inside the cage by an injection nozzle, thereby performing a degreasing step so that a sufficient degreasing process is performed.

Next, in the present invention, a rinse step is performed in which a degreasing step is carried out in a cleaning tank, and a rinse step is performed in which a degreasing solution is removed by circulating the recovered water by repressurizing and spraying the water while pressurizing the water. A rinse step for removing the water contained in the metal scrap is performed.

In this process, a rinsing step is performed for a predetermined time, and the resultant is put into a drying chamber. A hot air heated by a heater is sprayed at a high speed through a plurality of air discharge openings provided on the left and right sides of the drying chamber. A drying step of passing through a heat exchanger,

A fine scrap cleaning step of collecting the fine scrap generated in the pre-treatment step, the degreasing step, the rinsing step and the drying step, cleaning the fine scrap using the water, discharging the wastewater and recovering the micro-strap, Containing oil removal method is carried out.

Hereinafter, the metal waste-containing oil removal method will be described in more detail with reference to the metal waste-containing oil removal apparatus for the sake of convenience.

In the present invention, metal scrap is put into a cage (100) surrounded by a steel wire net. 4, the cage 100 is suspended at the lower end of the hoisting chain 110 of the crane lifting device 101, moved to the pretreatment tank 103, and released from the hoisting chain 110 at the upper side thereof The cage 100 is lowered to stop at a preset height.

In the present invention, in order to close the discharge valve 104 at the lower end of the pretreatment tank 103 and remove the oil from the metal scrap, the solvent must be filled in the pretreatment tank 103 so that the liquid level is above the cage 100, The liquid surface height is filled with the solvent at a predetermined optimum level with the solenoid valve 105 opened using the liquid surface detecting probe and the solvent supply pump or other known means not shown and the discharge valve 04 closed.

In addition, solvents usable in the present invention include, but are not limited to, octamethylcyclotetrasiloxane, dodecamethylcyclohexanesiloxane, decamethylcyclopentasiloxane, propylene glycol methyl ether, propylene glycol n-propyl ether, propylene glycol t- Butyl ether, dipropylene glycol n-propyl ether, dipropylene glycol t-butyl ether, dipropylene glycol n-butyl ether, tripropylene glycol methyl ether, tripropylene glycol n-propyl ether, Perfluorobutylamine, MC (Methyl Chloride), TCE (Tri Chloro Ethylene), and the like are used as the solvent for the reaction. One of the substances can be selected for use alone or in phase One or more substances from the material described can be mixed, and used as a useful alternative solvent for the removal of oil and other possible as a matter of course.

After the cage 100 is filled with the solvent in this way, the circulation pump 106 is operated. The solvent sucked in the lower part of the cleaning tank reaches the chamber 108 via the circulation pump 106 and is sprayed to the metal scrap of the cage 100 from the spray nozzle 108 provided on the inner peripheral wall surface of the pretreatment tank 103 The injection pressure is dispersed according to the shape of the irregular metal scrap, and circulated between the metal scrap and discharged to the outside together with the oil fractions.

The injection pressure at this time is determined by the capacity of the circulation pump 106, the diameter of the injection nozzle 108, and the like. In this way, the solvent and the oil are moved together from the bottom of the washing tank to the filter 107, the filter 107 collects the oil, and the small metal scrap is collected to the lower side of the washing tank because of its high specific gravity. The downstream discharge valve 104 is opened and processed in the micro scrap cleaning step.

In addition, the filter 107 in which the oil is collected in the pretreatment step shown in FIG. 4 is selected to have a capacity enough to collect the oil separated from the metal scrap by at least one amount in the at least one cage 100, It is of course possible to operate continuously. In this process, the solvent is used to remove oil contained in the metal scrap to a primary target oil content or less. Thereafter, the operation of the circulation pump 106 is stopped and the crane lifting device 101 is operated The process of raising the cage 100 by a height of, for example, 3 m, descending by a height of 1 m above the surface of the solvent, and then rising again is performed 5 to 10 times so that the solvent of the metal scrap after the pre- 103) so that it can be recovered and recycled.

In the present invention, after the pretreatment step is completed, the cage 100 is moved to reach the upper part of the degreasing body 200, and the degreasing step is performed. 5, a crane lifting device 101 is installed above the degreasing body 200 and a spray nozzle (not shown) having a chamber 209 is provided around the inner wall of the degreasing body 200 208 are installed. A water supply pipe 213, an alkaline liquid supply pipe 211 and an additive supply pipe 212 are disposed above the degreasing body 200 together with the solenoid valves 214, respectively. The reason for using the alkaline solution for degreasing in this manner is for the cleaning operation through the saponification reaction with the oil, oil, organic matter and the like contained in the metal scrap.

In addition, as the temperature of water increases, the surface tension decreases, the kinetic energy of water molecules increases, and when the surface tension is lowered, the degreasing agent can easily penetrate. Therefore, when working at the temperature of 80 ° C. or higher, In consideration of the degreasing performance, the heating means HT is applied as described later. Alkaline solution capable of reaching such a common degreasing performance, caustic soda (NaOH), sodium carbonate (Na ₂ CO _3.), Ortho-sodium silicate (Na ₄ SiO _4), meta-sodium silicate (Na ₂ SiO _3,), phosphoric acid soda (Na ₃ PO ₄ ) and caustic potassium (KOH), and it is possible to use any one of various kinds of surfactants, builders such as inorganic neutral salts, alkali neutral salts, sodium silicate and acidic salts, and tripolyphosphate, alkylbenzene A sequestering agent prepared by copolymerizing a metal ion by copolymerizing sodium monophosphate, sodium sulfonate, ethylenediamine tetraacetic oxygen, ester, or acrylate monomers, an antifoaming agent such as ethanol or silicone oil ) Is added and used.

Further, in the present invention, anionic and non-ionic surfactant groups such as higher fatty acid soap, lauryl lactate, and cetyl lactate such as sodium lauryl sulfate, and the like are used to reduce the surface tension of the degreasing solution to reduce interfacial energy, , A sulfonate such as an alkylbenzene sulfonate or the like, or a phosphoric acid ester such as polyoxyethylene alkylphenyl ether acid or the like is supplied to the degreasing body 200 through the additive supply pipe 212 and the electromagnetic valve 214 It prevents segregation of inorganic salts, alkali neutral salts, sodium silicate, and acid salts, and penetrates pollutants attached to the surface of metal waste due to wet permeation action to promote saponification reaction and emulsification reaction, thereby improving the degreasing power.

 In addition, the degreasing solution circulated by the circulation pump 206 reaches the mixer 230 via the electrolytic water treatment tank 201 on one side. 6, the external air introduced into the air fan 215 is supplied to the active gas generator (AG) having a built-in discharge electrode 217 at a high voltage supplied from the high voltage generator 216, In this case, the high electric field energy applied in the discharge process is applied to the air molecules so that the water molecule covalent bonds of the nitrogen molecules, the oxygen molecules, and the water constituting the air are dissociated, ionized, excited, oxidized and reduced (O2), oxygen ions (O2 *), hydrogen cations (H +) and OH-Radical are generated by the electrochemical reaction of the oxygen atoms ).

The mixed solution (hereinafter referred to as 'degreasing solution') introduced into the degreasing body 200 such as alkaline solution and water introduced by the circulation pump 206 is filtered through the filter 207 and impurities are filtered to the water treatment tank 201 The water treatment tank 201 can minimize the amount of wastewater discharged by filtering the degreasing solution such as an alkaline solution that is contaminated in the degreasing step with the filter 207. The specific structure of the waste water treatment tank 201 is shown in FIG.

As shown in the drawing, the present invention is characterized in that a plurality of electrodes 205 to which a voltage supplied by a second rectifier 219 is applied while being pressurized by a circulation pump 206 and flowing into an upper portion of the water treatment tank 201, In this process, in the cathode, the oxygen in the alkaline cleaning liquid is reduced to water as shown in Equation (1).

O ₂ + 2H ₂ O + 4e -? 4OH - - - - (1)

Also, the oxygen in the alkaline scrubbing liquid undergoes partial reduction reaction with water as in (Equation 2).

O ₂ + 2H ₂ O + 2e -? H ₂ O ₂ + 2OH - - - (Formula 2)

Further, the water of the alkaline cleaning liquid may be evolution to hydrogen as shown in (Formula 3).

2H ₂ O + 2e -? H ₂ + 2OH - - - (Formula 3)

In addition, the former is consumed by reduction at the cathode, and the metal oxidation reaction occurs at the anode as in (Equation 4).

M - > Mn + ne - - (4)

Where e refers to electrons, M refers to metal atoms, and n refers to integers.

The oxidation reaction proceeds by the OH-radical generated by the electrolytic action, so that the pollutants in the alkaline cleaning liquid are firstly purified, and the sludge generated in the purification process is decomposed in the lower part of the water treatment tank 201 Then, the lower discharge valve is opened and collected into the sludge collecting box. Meanwhile, the degreasing solution, which has been oxidized and has been removed in the above-described process, is supplied to the mixer 230 through the discharge pipe 203.

In this way, the active gas generated from the active gas generator AG and the carbonic acid gas supplied from the carbonic acid gas supply means 240 are collected in addition to the degreasing solution passed through the water treatment tank 201, Mixed. The carbonic acid gas supply means is a carbon dioxide gas supply means in which a carbon dioxide gas (CO ₂ ) is compressed and filled at 120 atmospheric pressure in a container at a professional manufacturing factory, and the pressure is reduced to 200 mmAq at a pressure reducer 242 connected to the upper portion of the container body 241 The valve body 243 provided on the pipe is opened and supplied to the air diffuser 231 in the mixer 230 to be sprayed into the alkaline cleaning liquid. (OH) ₂ }, magnesium (Mg), and the like react with hydroxide ions (OH-Radical) in the active gas to inhibit the degreasing power because metal ions such as calcium ions and magnesium ions are contained in water and industrial water. (OH-Radical) which is an active group in the process of producing hydrate {Mg (OH) ₂ } and the like. In order to prevent deterioration of the degreasing power, carbon dioxide gas (CO ₂ ) is separately supplied to the degreasing solution flowing into the mixer and dissolved in water to react with the calcium ions and magnesium ions present in the water to form calcium carbonate salts (CaCo ₃ ) It is precipitated with a salt (MgCo ₃ ) to prevent degreasing performance deterioration.

When carbonic acid gas (CO ₂ ) is supplied, sodium carbonate (Na ₂ CO ₃ ) and potassium carbonate (K ₂ Co ₃ ) are reacted with sodium ions (Na +) and potassium ions (CO ₂ ) is supplied to the degreasing and degreasing cleaning tanks at the initial stage of operation and the industrial water, or when the water is replenished at regular intervals during the process, The carbonic acid gas (CO ₂ ) is supplied to precipitate and discharge the calcium carbonate salt, the magnesium carbonate salt, and the like described above.

11 shows the structure of the mixer 230. The mixer 230 includes an air diffuser 231 made of a membrane material having a plurality of micropores in the mixing medium 232, And one side of the mixing body 232 is connected to the outlet of the water treatment tank 201. The other side of the mixing tube 232 is connected to the inside of the mixing tube 232 and the active gas generator AG, And the outside of the mixing body 232 communicates with the chamber 209 having the injection nozzle 208 through the quantum energy generating means 220. [

The quantum energy generating means 220 may be any one of a Moebius coil (also referred to as a Caduceus coil) or a Tesla coil (also referred to as a non-resonant toroid coil) You can choose either one.

As shown in FIG. 7, the Möbius coil and the Tesla coil are formed in a configuration in which the winding directions of the first coil 221 and the second coil 222 are opposite to each other, and the first coil 221 and the second coil 222 As shown in FIGS. 8 and 9, by connecting a power source 223 having the same frequency, the same voltage and current, the magnetic field formed by the coil 1 221 and the magnetic field formed by the coil 2 222 As shown by the arrows, by reversing each other and canceling each other, the total magnetic field will be zero, but in reality, subtle energy (hereinafter referred to as "SE") is generated.

Such SE is also referred to as Scalar energy or non-Hertzian as quantum energy, but will be collectively referred to as quantum energy in the present invention. The nitrogen atom (N), the oxygen atom (O), the nitrogen ion (N ₂ ), the oxygen ion (O ₂ ), the hydrogen cation (H +) and the OH-Radical generated by the active gas generator When electric power is supplied to the coil 221 (221) and the coil 2 (222) and the magnetic field generated in the direction perpendicular to the flow direction of the electric current is applied to the alkali degreasing solution dissolved in the solution and contained in the bubble form, When a magnetic field generated in a direction perpendicular to the direction of current flow is applied to the coil 1 (221) and the coil 2 (222) due to the force, the electric field and the magnetic field are generated by the Lorentz force And increases the average path of the ions described above near the applied magnetic field.

Further, the windings of the coils 1 221 and the coils 2 222 are wound in opposite directions to supply power, and magnetic fields generated in the direction perpendicular to the direction of current flow are generated in mutually opposite directions, And the direction of the Lorentz force acting on the electric field and the magnetic field in the direction opposite to each other also act on the coil 2 222 and the magnetic field generated in the flow path of the degreasing solution between the coil 1 221 and the coil 2 222, The bubbles of the active gas described above in the degreasing solution are collided and defoamed to generate a small microcapsule in which a part of the active gas is dissolved in the alkaline solution and the dissolved ions in the water are further activated, The distribution (density) of the active ions in the alkaline solution becomes uniform in the region where the Lorentz force becomes zero and the magnetic field generated in the opposite direction in the coil 1 (221) and the coil 2 (222) SE is added to the active ions in the alkaline solution to further activate the active ions.

In addition, the distribution (density) of the active ions in the alkaline solution is made uniform, the active gas is made fine, more uniform degreasing performance can be ensured and the degreasing performance is improved.

Thus, OH-radicals, unstable ozone and carbon dioxide, which are the main components of the active gas, and degreasing solution purified by the water treatment tank 201 are mixed in the mixer 230. After the SE is irradiated as described above, Is sprayed onto the metal scrap of the cage 100 via the injection nozzle 208 via the spray nozzle 209.

Particularly, in this process, a large amount of air bubbles are injected from the injection nozzle 208 because the active gas and carbon dioxide gas are ejected from the air diffuser 231, which is a membrane of the mixer 230.

In this way, the degreasing solution sprayed by the spray nozzle 208 has the most powerful effect of chemically decomposing and removing most contaminants, while ozone as an active gas, which is an environmentally harmless natural substance, is unstable And carbonic acid gas is injected from the spray nozzle 208 to form bubbles, and OH- with a negative charge around the fine bubbles attached to the metal scrap are gathered to form the quantum energy generating means 220) is negatively charged as a whole.

Since the active gas bubbles mixed in the mixer 230 exist in a spherical shape, when the active gas bubbles are ruptured, the surface tension instantaneously generates high heat from the force of compressing the gas to improve the cleaning effect .

In this way, the bubbles of the active gas in the alkali solution in the electrolytic degreasing main body 200 are negatively charged, and the OH radicals generated by the bubbles of the active gas and the bubbles of the active gas, Can be effectively removed.

More specifically, OH-Radical of the bubble of the active gas having a negative charge is collected around the metal scrap containing oil charged by the negative electrode (- pole), and the bubbles of the active gas are further ruptured to generate energy and shock waves It is possible to further dissociate the oil molecules on the metal scrap, thereby accelerating the separation of oil from the metal scrap.

In addition, in the present invention, by using the first rectifier 202 to flow current, it is possible to help gather the bubble of the active gas and OH-Radical around the metal scrap.

That is, as shown in FIG. 5, when an anode is attached to a metal scrap and a cathode is connected to the degreasing body 200 and a current is applied to the degreasing body 200, the metal scrap is charged to the cathode, Radical is further concentrated around the metal scrap containing oil charged with the negative electrode (- pole) to further defoam the active gas bubbles around the metal scrap containing oil, and in the electrolysis reaction between the anode and the cathode, The hydrogen generation reaction in which hydrogen is reduced and the hydrogen generation reaction is generated, and the removal effect of the oil attached to the metal scrap can be improved by the hydrogen off-gas generated.

In addition, in the present invention, the degreasing solution is sprayed at a considerable pressure, and the fine scrap separated from the surface of the metal scrap and discharged to the outside of the cage 100 is collected below the degreasing body 200. If the scrap is accumulated more than a predetermined amount, The discharge valve 204 is opened and treated with the micro scrap cleaning step described later.

The cage 100 with the oil removed by the degreasing process is wound around the hoisting chain 110 by the crane lifting device 101 and the cage 100 is lifted about 1 meter from the surface of the degreasing solution The crane lifting device 101 travels on the rail 102 to move the cage 100 to the rinsing main body 100. [ 301).

Accordingly, the amount of metal scrap that can be contained in the cage 100 by the fluid passage 704 can be reduced by encroaching the metal scrap charging space. However, since the fluid passage 704 is three-dimensionally secured, .

Therefore, it is needless to say that the embodiments of FIGS. 20 and 21 can be selectively used in consideration of the degree of content of oil in scrap metal, the type of oil, and the optimum process time for each site.

Accordingly, the temperature of the degreasing solution is increased to, for example, about 80 ° C., the surface tension with the oil is reduced, so that the oil scrap can be efficiently removed from the metal scrap. In addition, The same SE energy as that of the above-described quantum energy generating means 220 is generated so that the active gas of the degreasing solution is further activated so that the oil fractions of the metal scrap can be more efficiently activated by OH-radical and unstable ozone It can be removed.

The present invention can further improve the oil removing performance by performing bubbling in which the bubbles are sprayed toward the cage on the bottom surface of the pretreatment tank and the rinsing main body in the pretreatment and rinsing steps.
