The present invention relates to an apparatus for reusing combustion waste generated in a thermal power plant or the like as resources by using fly ash generated after coal is burned in the thermal power plant instead of cement as construction materials such as a ring-forming covering material or the like, in order to solve problems such as a decrease in compressive strength when ash is reused due to unburned carbon components in fly ash and a glass film applied to the surface of ash particles.

Background

Fly ash is a particle of μm size generated during combustion of coal in a thermal power plant for power generation, and the particle may include Silica (SiO)₂) Alumina (Al)₂O₃) Iron (Fe)₂O₃) And various oxides and residual carbon (coal dust carbon).

Fly ash has many uses as an additive to a variety of substances. For example, if mixed with lime and water, fly ash will form a cement composition (cement composition) having properties very similar to those of portland cement. Because of this similarity, fly ash can replace a portion of the cement in concrete.

When the fly ash is used for preparing concrete, the amount of cement used can be reduced, and the amount of carbon dioxide generated in the cement preparation process and the preparation cost can be reduced correspondingly, and moreover, the effects of improving the performance such as convenience of construction, improvement of long-term strength and chemical durability due to the increase of fluidity can be obtained.

However, in the case of using fly ash as a concrete admixture, the fly ash is rapidly frozen at a high temperature during the generation of the fly ash, and thus, a glass film is formed on the surface to exhibit a potential hydraulic property that does not directly react with water, and such a glass film has a property of being destroyed when exposed to an alkaline environment, and in general, a glass film is formed using, for example, sodium hydroxide (NaOH), potassium hydroxide (KOH), calcium hydroxide (ca (oh))₂) The alkaline stimulant of (a) to cause a hydrolysis reaction.

However, in order to solve such problems, when a strongly alkaline substance is used as a material to replace the alkaline stimulant, there is a risk of corrosion of the skin when the alkaline stimulant comes into contact with the skin of a worker, and the cost of the alkaline stimulant is increased as an expensive material.

Further, unburned carbon (coal dust carbon) exists in the fly ash, and the unburned carbon does not completely burn in the boiler of the thermal power plant but remains as amorphous carbon particles, and when a large amount of fly ash mixed with the unburned carbon is used as a cement substitute, a large amount of air entraining and water reducing Agent (AE) water reducing agent needs to be added to secure the same bottleneck, and this causes a problem of performance degradation such as reduction in durability.

When fly ash is added to concrete, it provides preferable characteristics of cement, and since unburned carbon in fly ash may cause insufficient air mixing in concrete, it is necessary to add a surfactant to the concrete mixture in order to adjust the air mixing amount in the mixing and casting process of concrete, thereby stabilizing the air void (air void) system.

As noted above, there is a need to provide improved methods and systems for treating fly ash that overcome the difficulties of liquid phase treating agents with bulk fly ash.

Also, there is a need to provide a uniform fly ash production process and system that does not require large changes in the current process of producing and treating fly ash, thereby minimizing the capital costs associated with the process.

In order to treat the fly ash, korean patent No. 10-1801530 (a fly ash treatment apparatus and a fly ash treatment method using the same) discloses a method of separating a treatment gas containing ash and sulfur compounds by collecting exhaust gas discharged from a coal-fired power plant, preparing sulfuric acid from the separated sulfur compounds, contacting the prepared sulfuric acid and ash to form a mixture, separating a slurry and an extract from the mixture, and drying the separated slurry and extract.

Korean patent publication No. 10-1547959 (a method of recovering unburned carbon from bottom ash by corona discharge electrostatic screening) discloses a technique of recovering unburned carbon from bottom ash generated after burning coal in a thermal power plant, recovering unburned carbon and separating the unburned carbon into particle sizes in order to use the buried bottom ash as a building material, etc., removing crushed and floating impurities in order to improve screening efficiency, performing screening work in order to concentrate the unburned carbon content, applying a magnetic field of 2000 gauss suspended from the bottom ash from which unburned carbon is concentrated to separate iron powder, and recovering unburned carbon from the bottom ash from which iron powder is separated in a corona discharge type typical screening process, which cannot remove a glass film of bottom ash particles.

In Korean patent application No. 10-1514124 (method for removing unburned carbon from fly ash by plasma), 1.2g of fly ash is dispersed into a chamber in a plasma treatment process, and then oxygen (O) is added₂) Water vapor (H)₂O), mixed fluid of oxygen and water vapor (O)₂+H₂O) and the like, and then the fly ash is removed by heating at 150 ℃ after reducing the pressure inside the chamber to 0.5torr until the concentration of the fly ash is less than 1%, and in the above-mentioned technique, there are a problem that the pressure inside the chamber is reduced to 0.5torr, a problem that the oxidizing agent is continuously consumed, and a glass film on the surface of the fly ash particles cannot be taken out, and in the process of increasing the size, the apparatus becomes complicated, and enormous investment costs and maintenance costs are consumed.

As described above, in the conventional thermal power plant, the fly ash treatment technology for recovering from the gas of coal burned in the process is a part lacking in treatment efficiency due to the above-described problems, and a specific proposal for performing treatment with a large capacity while ensuring stability and durability has not been proposed yet.

According to the apparatus for recycling fly ash with a built-in glass film removal function of the present invention, unburned carbon components in fly ash are ionized, collected in the electrostatic dust collector, and then the collected unburned carbon components are removed by a combustion reaction, so that when the apparatus is used as a material for replacing cement, the apparatus can be reused without requiring a large amount of water reducing agent in the process of ensuring a surfactant or a bottleneck for securing air voids.

However, the problem of potential water hydraulicity that the glass film on the surface of the fly ash cannot be directly reacted with water can be solved.

And, the glass film on the surface of the fly ash is removed, thereby using the fly ash to increase compressive strength when concrete is cast.

Further, when concrete is prepared using fly ash, the amount of cement used can be reduced, and the amount of carbon dioxide generated in the cement preparation process and the preparation cost can be reduced according to the reduced amount of use, and moreover, the effects of improving the performance such as the convenience of construction, the improvement of long-term strength, and the improvement of chemical durability due to the increase of fluidity can be obtained.

Meanwhile, combustion waste generated in a combustion process of a thermal power plant or the like can be reused as a resource.

electrodes

342, 343 by the high voltage generator 341 and the separation distance D between the two

electrodes

The amount of combustion heat in the combustion reaction formula 1, the combustion reaction formula 2, and the combustion reaction formula 3 increases the temperature inside the main body 301, and therefore, the amount of electric power supplied from the power supply 351 to the heating element 352 of the heating portion 350 can be reduced by the amount corresponding to the amount of combustion heat in the combustion reaction formula 1, the combustion reaction formula 2, and the combustion reaction formula 3, and the amount of combustion supplied to the burner 362 of the combustion portion 360 can be reduced.

In the second barrel 412 protruding upward, a second spur gear 413b is inserted into the upper surface of the main body 401 at an interval, and a central portion having a size that allows the interval to be left in the outer diameter of the second barrel 412 is perforated in the circumferential surface of one side of the second barrel 412.

Also, the first motor 413 and the second spur gear 413b are engaged with each other, and the first spur gear 413a having a diameter larger than that of the second spur gear 413b by 1 to 5 times is provided at the end of the rotation shaft of the motor 413.

A plurality of copper ring-shaped connectors 413e are provided on the outer peripheral surface of the outer surface of the second barrel 412 so as to be insulated from the second barrel 412 by a predetermined height, at intervals in the upper direction from the second spur gear 413 b.

When the control panel 600 supplies power to the first motor 413, the first motor 413 is driven to rotate the first spur gear 413a connected to the shaft by a rated revolution number (RPM) of the motor 413, and at the same time, the revolution number (RPM) of the meshed second spur gear 413b is increased by a diameter difference between the second spur gear 413b and the first spur gear 413a, so that the second drum 412 and the first drum 411 fixed to the second spur gear 413b rotate at high speed.

When the first drum 411 rotates, the fluid (a mixture of fly ash, air, a fluorine compound, and water vapor) located on the first drum 411 side has a direction of moving toward the main drum 401 by centrifugal force in the passage 402 formed between the main drum 401 and the first drum 411, and the fluid becomes unstable, and a vortex flow in which the pair of rings rotates regularly and in the opposite direction is formed along the first drum 411 (the rotation axis). It is called taylor or couette flow.

The vertical cross section of the first barrel 411 is elliptical, the vertical cross section of the body barrel 401 is circular, and the center axes (longitudinal axes) of the barrel-shaped body 401 and the first barrel 411 of the elliptical barrel shape are arranged in concentric circles, so that the interval D between the body barrel 401 and the first barrel 411, that is, the interval between the long-side end of the first barrel 411 and the inner face of the body barrel 401 and the interval between the short-side end of the first barrel 411 and the inner face of the body barrel 401 do not change with time but are constant during the rotation of the first barrel 411. Since the number of rotations of the first drum 411 is the same as the number of rotations of the first spur gear 413a that is engaged with the second spur gear 413b fixed to one side surface of the second drum 412 by being connected to the second drum 412 via the flange 413d, the linear velocity V of the long side end and the short side end of the first drum 411 is constant. Thus, over time, the conditions in the passageway 402 do not change the linear velocity V, but are constant, except that the first barrel 411 is merely swirling by relative rotation with respect to the body barrel 401, and therefore the fluidity of the swirl is limited. In order to solve the above problem, the hollow structure is formed by the body drum 401 and the first drum 411 sharing the longitudinal axes 411 and 412 together, and the fluid passage is formed between the body drum 401 and the first drum 411, in the body drum 401, the cross section perpendicular to the longitudinal axes of the first drum 411 and the second drum 412 is circular, in the first drum 411, the cross section perpendicular to the longitudinal axes is elliptical, in order to reinforce the relative rotational motion of the body drum 401 and the first drum 411 with the longitudinal axes 411 and 412 as the rotation axes, in order to increase the Revolutions Per Minute (RPM) of the first drum 411, the Revolution (RPM) of the motor 4413 is adjusted to an appropriate revolution selected by a field test, the Revolution (RPM) of the second drive motor 407 is driven and the Revolution (RPM) is adjusted to adjust the revolution of the body drum 401 to an appropriate Revolution (RPM) selected by the field test, or, the rotation directions of the body drum 401 and the first drum 411 are rotated in opposite directions, the rotation number (RPM) of the second driving motor 407 is adjusted to an appropriate rotation number (RPM) selected by a test to increase the rotation number (RPM) of the body drum and the first drum 411, and the rotation number (RPM) of the motor 4413 is adjusted to an appropriate rotation number (RPM) selected by a field test to adjust the rotation number of the first drum 411, thereby solving the problem of the restriction of the fluidity of the vortex in the passage 402, the fly ash supply part 420 for supplying the fly ash is formed on an upper part of one side surface of the body drum 401, and the discharge port 403 for removing the fly ash of the glass film interlocked with the passage 402 is formed at the rear end part of the body drum 401.

In order to maintain the flow of the vortex in the passage continuously and positively, a frequency converter control circuit is attached to the first motor 413 so that the number of Revolutions (RPM) of the second drum 412 connected to the first drum 411 through the flange reaches an appropriate number of revolutions in the range of 1RPM to 500RPM, the number of Revolutions (RPM) of the second drum 412 is adjusted, and a frequency converter control circuit is attached to the second drive motor 407 so that the number of Revolutions (RPM) of the body drum 401 reaches an appropriate number of revolutions in the range of 1RPM to 5000RPM, thereby adjusting the number of Revolutions (RPM) of the body drum 401.

Further, when the main body drum 401 is stopped, if the first drum 411 is rotated at a rotation speed selected from a range of 1RPM to 5000RPM (for example, 500RPM or more) by the driving of the first motor 413, centrifugal force acts in the direction of the main body drum 401 in the passage 402 formed between the main body drum 401 and the first drum 411 to generate turbulent flow, and if the first drum 411 is stopped, the rotation speed selected from a range of 1RPM to 5000RPM (for example, 500RPM or more) by the driving of the second drive motor 407, centrifugal force acts in the direction of the first drum 411 to generate turbulent flow in the passage 402 formed between the main body drum 401 and the first drum 411, and such turbulent flow is couette flow, and if the main body drum 401 is stopped and the first motor 413 is driven, the first drum 411 has a cylindrical shape with an elliptical distal end surface, that is, when the diameter difference between the long side and the short side of the ellipse is such that the rotation speed of the first motor 413 is 500RPM or less, the rotation speed of the first barrel 411 receiving the rotation force of the first motor 413 is also 500RPM or less, and the flow of the fly ash in the passage 402 does not form an irregular turbulent flow and does not generate a sufficient centrifugal force, thereby intermittently forming the couette flow, and therefore the fly ash having a specific gravity of 2.15 or more cannot be sufficiently scattered (floated) in the passage 402, and therefore, the rotation speed is adjusted by the frequency converters of the rotation speed control device for the first motor 413 and the second drive motor 407 provided at 500RPM or more, respectively, so that the fly ash particles are sufficiently scattered at the rotation speeds of the first motor 413 and the second drive motor 407.

At the same time, the first drive motor 413 and the second drive motor 407 are driven, and the centrifugal force acting in the opposite direction of the first barrel 411 receiving the rotational force of the first drive motor 413 and the main body barrel 401 receiving the rotational force of the second drive motor 407 collides with each other in the passage 402 formed between the main body barrel 401 and the first barrel 411 to form a vortex or spiral turbulent flow, thereby forming a further improved couette state.

As shown in fig. 7d, the high voltage discharge unit 450 includes a discharge electrode 451, a ground electrode 452, a high voltage generator 453, a lead 454, and a connector 454 a.

The discharge electrode 451 and the ground electrode 452 have a circumferential surface shape having a predetermined radius of curvature with a predetermined height, the discharge electrode 451 or the ground electrode 452 provided in the main body cylinder 401 protrudes in a triangular or hemispherical shape on the inner circumferential surface, the discharge electrode 451 or the ground electrode 452 provided in the first cylinder 411 protrudes in a triangular or hemispherical shape on the circumferential surface, and the discharge electrode 451 or the ground electrode 452 is inserted into a hole perforated in a predetermined diameter on the circumferential surface by insulation treatment with a gap between the cylinder 401 and the first cylinder 411. The passages formed between the barrel 401 and the first barrel 411 are provided to face each other.

The lead wire 545 connected to the discharge electrode 451 or the ground electrode 452 provided in the first barrel 411 is connected to the voltage application ring 454a provided in the second barrel 412 through the inside of the first barrel 411, and the external lead wire 545 connected to the voltage application ring 454a is connected to the high voltage generator 453.

The high-voltage discharge may be arc discharge, corona discharge, glow discharge, or spatter discharge, and a preferred discharge method is arc discharge.

Arc discharge is one of discharges generated in the air by a potential difference between anodes when the anodes and cathodes are opposed to each other, and a voltage applied to a discharge electrode has a voltage of several volts or several tens of volts, and a discharge region in which a current of several amperes or more flows.

Unlike glow discharge and spatter discharge, arc discharge has characteristics that when discharge is started, voltage is reduced and current is increased, and in particular, thermions are emitted on the surfaces of the

electrodes

451 and 452 by the action of a cathode due to heating.

In the arc discharge region, electrons will move at high speed and gain energy, and elastically collide with other particles to transfer energy. In this case, the temperature of the particles rises, and through the inelastic collision process, ionization and excitation (excitation) of the particles to a high energy level occur, and arc discharge continues to occur.

In addition, in the process of generating the arc discharge, electrons and thermal electrons move between the

electrodes

451, 452 at a high speed, and energy is taken in the process of elastic collision of particles that acquire high energy per unit time, and in this case, high-temperature heat is generated. The temperature reaches 3000-6000 ℃. In the inelastic collision process occurring after the elastic collision, light (spark) is generated in the process of releasing ionization and excitation to the energy level of the particles.

Then, a high voltage generated by the high voltage generator 453 is applied to the discharge electrode 451 and the ground electrode 452 of the high voltage discharge unit 450 through the lead 454 and the connector 454a to start discharge between the discharge electrode 451 and the ground electrode 452, thereby discharging charged particles such as electrons and ions and thermoelectrons discharged from the electrodes 451 and 452 heated at a high temperature, and making the thickness of silicon dioxide (SiO) larger than that of a glass film between the discharge electrode 451 and the ground electrode 452₂) Work function value of 5.0eV, work function value of 1.6eV of calcium oxide (CaO), work function value of 4.7eV of magnesium oxide (MgO), work function value of 1.1eV of barium oxide (BaO), and work function value of aluminum oxide (Al)₂O₃) Electric field energy (IE, eV) of 5.0eV in the range of 5eV to 5KeV, charged particles such as electrons or ions, and a high temperature passing gasThe elastic collision of the thermal electrons emitted from the heated electrodes 451, 452 with the fly ash removes the glass film coated on the surfaces of the fly ash particles and promotes the unreacted silicon dioxide (SiO) in the region of the electric field energy (IE, eV) ranging from 5eV to 5KeV₂) Calcium oxide (CaO), barium oxide (BaO), magnesium oxide (MgO), and aluminum oxide (Al 2O)₃) The chemical reaction of the substance with the fluorine compound and the hydrolysis reaction of the substance with water vapor improve the removal efficiency of the glass film coated on the surface of the fly ash particles.

The high voltage generator 453 of the discharge unit 440 has an output voltage of 12V or more in the case of a direct current (d.c) power source, 110V or more in the case of an alternating current (a.c) power source, and in the case of both the direct current power source and the alternating current power source, which is in the range of 1KV to 50KV, and the output voltage selected in consideration of the removal performance of the glass film surrounding the surface of the soot particles is selected and output in the high voltage generator 453.

Therefore, in the present invention, one of the methods for improving the glass film removal efficiency is that in the passage 402 formed between the main body cylinder 401 having the discharge electrode 451 or the ground electrode 452 on the inner surface thereof and the first cylinder 411 having the discharge electrode 451 or the ground electrode 452 on the outer surface thereof, the high voltage generated by the pressure generator 453 is applied to the high discharge electrode 451 and the ground electrode 452 through the lead wire, and when the discharge starts between the two

electrodes

451 and 452, the first cylinder 411 has a circular cylindrical shape in cross section, and therefore, when the distance separating the passage 402 and the main body cylinder 401 is the long side of the first cylinder 411, the distance separating is small, and the high voltage discharge starts uniformly, but when the distance separating is the short side, the distance separating is longer than the long side, and thus, the irregular discharge is generated. Further, a uniform high field region cannot be maintained in the passage 402 due to the difference between the discharge electrode 451 and the ground electrode 452 provided on the outer surfaces of the main barrel 401 and the first barrel. In order to solve the above-mentioned problems, in order to make the flow of the fly ash such as air, fluorine compounds and water vapor in the mixing passage 402 in the couette flow state, the second drive motor 407 is driven to rotate the third spur gear 408 connected to the shaft, the rotational force is transmitted to the fourth spur gear 409 provided on the circumferential surface of the lower part of the main body drum 401 meshed with the third spur gear 408 to rotate the main body drum in the clockwise direction or the counterclockwise direction at the number of Revolutions (RPM) selected from the range of 10RPM to 5000RPM, and the first motor 413 is driven to rotate the first spur gear 413a connected to the shaft, and the rotational force is transmitted to the second spur gear 413b provided on the circumferential surface of one side surface of the second drum 412 connected to the flange provided on the upper surface of the first drum 411 to rotate the first drum 411 connected to the lower part of the second drum 412 in the same direction or the opposite direction to the rotational direction of the main body drum 401, thereby initiating a uniform discharge in via 402.

Further, when the main body drum 401 is stopped and the first motor 413 is driven, since the first drum 411 has a cylindrical shape with an elliptical distal end surface, when the rotation speed of the first motor 413 is less than 500RPM in the diameter difference between the long side and the short side of the ellipse, the rotation speed of the first drum 411 receiving the rotation force of the first motor 413 is also less than 500RPM, so that the flow of the fly ash in the passage 402 does not form a turbulent flow and does not generate a sufficient centrifugal force, thereby intermittently forming the couette flow, and therefore the fly ash with a specific gravity of 2.15 or more cannot be sufficiently scattered (floated) in the passage 402, and therefore, the form of removing the glass film coated on the fly ash particles in the high field electron energy band formed by the high voltage discharge in the discharge electrode 451 and the ground electrode 452 is not good, and when the rotation speed of the first motor 413 is 500RPM or more, the flow of the fly ash in the passage 402 forms a good turbulent flow and generates a sufficient centrifugal force, and thus a good couette flow is formed, the fly ash having a specific gravity of 2.15 or more is favorably scattered (floated) in the passage 402, a form of removing a glass film coated on the fly ash particles in a high-field electron energy band formed by high-voltage discharge in the discharge electrode 451 and the ground electrode 452 is favorable, the second drive motor 407 is driven to rotate the third spur gear 408 connected to the shaft, a rotational force is transmitted to the fourth spur gear 409 provided on the lower circumferential surface of the main body drum 401 meshing with the third spur gear 408 to rotate the main body drum 401 at 500RPM or more in the clockwise direction or the counterclockwise direction, the rotational force of the first motor 413 is 500RPM or more, and the rotational force is transmitted from the first spur gear 413a connected to the shaft to the second spur gear 413b to rotate the main body drum 401 in the counterclockwise direction or the clockwise direction opposite to the rotational direction of the main body drum 401 The flow of the fly ash particles in the passage 402 is changed to a swirl, spiral turbulence, or vortex flow such as a wave, and an irregular and strong centrifugal force acts to maintain a more improved couette flow, the flow of the fly ash particles in the passage 402 is extremely good, the removal form of the glass film coated on the fly ash particles in the high-field electron energy band formed by the high-voltage discharge in the discharge electrode 451 and the ground electrode 452 is extremely good, and the removal time is reduced to increase the throughput per unit time. By rotating the main body drum 401 and the first drum 411 in opposite directions, even if the rotational speed of the first drum 411 is lower than the speed of the main body drum 401, the flow of the fly ash in the passage 402 is subjected to a considerable centrifugal force, and a good couette flow can be maintained.

In order to effectively remove the glass film coated on the surface of the fly ash particles by forming the couette flow of various patterns in the passage 402 formed between the body drum 401 and the first drum 411, the first motor 413 and the second drive motor 407 need to be three-phase motors that can rotate in the forward and reverse directions, and a control circuit such as a frequency converter that can adjust the number of Revolutions (RPM) needs to be programmed and input to the control circuit of the control panel 600.

Anthracite coal used as a boiler fuel in a coal-fired power plant is largely divided into fixed carbon as a combustion substance, volatile powder, and ash and moisture as non-combustion substances.

Ash (ash) is a residue obtained by heating a humidity sample (1 g) from room temperature to 500 ℃ for 60 minutes, heating the humidity sample at 500 ℃ to 15 ℃ for 30 minutes to 60 minutes, and heating the humidity sample at 815 ℃ ± 10 ℃ until the change is completed, i.e., a non-combustible residue remaining after complete combustion of coal, in industrial chemical analysis. Generating electricity by coal energyIn the boiler of the plant, the ash trapped after smokeless carbon combustion contains Silica (SiO)₂) Aluminum oxide (Al) ₂O₃) Iron oxide (Fe)₂O₃) Calcium oxide (CaO), potassium oxide (K)₂O), sulfur trioxide (SO)₃) Magnesium oxide (MgO), phosphorus pentoxide (P)₂O₅) Titanium dioxide (TiO)₂) And an unburned carbon component (C), the main component of the glass film surrounding the fly ash particles being silicon dioxide (SiO)₂). Glass films, that is, glass, are highly brittle (i.e., break-down upon impact), and when heated, do not exhibit a predetermined melting point, but rather gradually decrease in viscosity and change to a liquid state. The glass film has a small tensile strength and a large compressive strength, but has a smaller mechanical strength than a theoretically measured value because it is discharged after being melted at a high temperature in a boiler and undergoes surface defects (flaw) or rapid freezing in a post-treatment (dust removal) process, and thus deformation (strain) is inevitably generated in the glass. Conductivity is dependent on soft glass (Na)₂O) component increases or temperature increases, the impedance will decrease. The erosion of chemical substances is carried out in hydrochloric acid (HCl) or sulfuric acid (H)₂SO₄) Is extremely slow, will react in large amounts in alkalis such as sodium hydroxide (NaOH) and in larger amounts in fluorides such as Hydrogen Fluoride (HF).

In view of the mechanical, chemical and electrical properties of the glass described above, in order to effectively remove the glass film surrounding the surface of the fly ash particles, it is necessary to form a higher energy band between the

electrodes

451 and 452, to further increase the elastic collision strength with the fly ash particles due to acceleration of electrons and thermoelectrons, to maintain the temperature of the passage space formed between the main barrel 401 and the first barrel 411 at a high temperature to improve the electrical conductivity of the glass, and to spray fluorine compounds and water vapor to the flowing fly ash to remove the glass film by chemical reaction and hydrolysis reaction with the main component substances of the glass film surrounding the surface of the fly ash particles, if necessary. When fly ash treated in such a manner as to sufficiently remove a glass film on the surface of the fly ash is used as a product instead of cement, can solve the potential problem of water hydraulicity which can not react with water, can increase the compressive strength when pouring concrete, therefore, in order to further improve the efficiency of removing the glass film coated on the surface of the fly ash particles, in order to form a higher high energy band between the

electrodes

451, 452, in the case of an alternating voltage (A.C), the input and output voltages of the power supply 453 for applying a high voltage to the discharge electrode 451 and the ground electrode 452 are 110V and 60Hz or higher, in the case of a direct current voltage (D.C) of 12V or more, and in the case of an alternating current voltage and a direct current voltage, the voltage value of the output side is selected to meet the field condition and the handling capacity in the range of 1KV to 500KV, in the case of frequency, the alternating voltage is selected in the range of 60Hz to 50KHz at a frequency that meets the field conditions and throughput.
