Description

Fly ash recycling device with built-in glassy membrane removal function {Apparatus for recycling fly ash having glassy membrane removal}

The present invention relates to a fly ash recycling device with a built-in glassy film removal function, and more particularly, to give air gaps between fly ash particles by spraying and mixing high-pressure air to fly ash in the electrostatic precipitating process, followed by fly ash particles in the high voltage discharge process. And after ionizing the air, the flow of fly ash particles sprayed to the electric dust collection unit is formed by the centrifugal force generated from the high-speed rotating jet hole to form a swirl flow, thereby creating an elastic collision between fly ash particles, ionized ash and high pressure air. The fly ash particles are charged in the process of friction with the inner surface of the jet hole during the mixing process of (+) and (-) the unburned carbon powder (C) of the fly ash particles that are charged at the (+) electrode of the dust collecting electrode and separated. And, the separated unburned carbon powder is removed by heating with a heating element or burning with the flame of the fuel burned in the burner, attaching a plurality of discharge electrodes along the circumferential surface on one side of the body cylinder, and at a certain interval inside the body cylinder. A ground electrode is installed on the outer surface of an oval cylinder (first cylinder) with both ends facing each other and discharge electrodes installed on one side inside the main cylinder, and both ends of the main cylinder and the second cylinder rotating with a motor attached The flow of the passage through which fly ash particles formed between the body cylinder and the first cylinder are connected to the elliptical, elliptical columnar first cylinder and rotated by the rotational force of the motor is turbulent. -Couette flow or Turbulent Tayler Voltex flow (TTVF)) is maintained in the fly ash supply pipe installed on one side of the top of the main body cylinder. By spraying high-pressure air, fluorine compounds and water vapor to the fly ash in advance, the fly ash particles and the air injected The pores between the particles are maintained, the fluorine compound chemically reacts with the main component material of the glassy film coated on the surface of the ash particles, and the water vapor hydrolyzes with the main component material of the glassy film coated on the surface of the ash particles. While supplying to the passage in the state of Couette flow or Turbulent Tayler Voltex flow (TTVF)) , The high voltage generated by the high voltage generator is applied to a plurality of discharge electrodes and ground electrodes installed on the inner surface of the body cylinder and the outer surface of the first cylinder sharing a path, thereby forming a high field energy band by discharge between the two discharge electrodes (path), Fly ash particles passing through the passage, charged particles of electrons or ions emitted from the discharge electrode in the discharge process, and hot electrons, and the glassy film coated on the surface of the fly ash particles in the elastic collision process are removed, and a certain number of turns are wound outside the main body cylinder. The heat generated from the coil by supplying power to the high-frequency induction coil increases the amount of hot electrons emitted from the surface by heating the discharge electrode and the ground electrode in a thermal conduction method, and increases the temperature of the passage formed between the discharge electrode and the ground electrode to prevent electrons or ions from being generated. Charged particles and hot electrons of electrons or ions are activated by supplying thermal energy to charged particles and hot electrons, and a magnetic field generated at an angle of 90 degrees in the current flow direction of the induction heating coil is discharged from the discharge electrode during the discharge process. And, by extending the residence time of the hot electrons, the glassy film coated on the surface of the fly ash particles is efficiently removed by increasing the number of elastic collisions between the fly ash particles and electrons, hot electrons, and electric charges.

By solving the problems such as lowering the compressive strength during recycling of ash due to the content of unburned carbon in fly ash and the glassy film coated on the ash particle surface, fly ash generated after coal combustion in thermal power plants is replaced with cement, eco-friendly cover material. It relates to a device for recycling combustion waste generated in thermal power plants, etc. as resources as construction materials, etc.

Fly ash is a micron (㎛)-sized particle generated during the combustion of coal in a thermal power plant that produces electricity. Among the particles, silica (SiO ₂ ), alumina (Al ₂ O ₃ ), iron (Fe ₂ O ₃ ) Etc. It may contain various oxides and residual carbon (pulverized coal).

Fly ash has many uses as an additive to various substances. For example, when mixed with lime and water, fly ash forms a cementitious composition with properties very similar to those of Falkland cement. Because of this similarity, fly ash can be used to replace some of the cement in concrete.

When concrete is manufactured using fly ash, the amount of cement used can be reduced, and the amount of carbon dioxide generated in the cement manufacturing process and manufacturing cost can be reduced by the reduced amount, as well as convenience of construction due to increased fluidity, long-term strength, and The effect of improving performance, such as improving chemical durability, can be obtained.

However, in the use of fly ash as an admixture of concrete, since fly ash is rapidly cooled at a high temperature during the generation process, a glassy film is formed on the surface and has a latent hydraulic property that does not react with water by itself. The glassy membrane has the property of being destroyed when exposed to an alkaline environment, and in general, it induces a hydration reaction using an alkali stimulating agent such as sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH) ₂ ).

However, in order to solve this problem, when a strong basic material is used as a substitute for an alkali stimulant, there is a risk of corroding the skin when it comes into contact with the skin of a worker, and the construction cost is increased as an expensive material.

In addition, fly ash contains unburned carbon powder (pulverized coal) inside, and the unburned carbon powder refers to irregular carbon particles that are not completely burned inside the boiler of a thermal power plant, and fly ash containing a large amount of such unburned carbon. When used as a cement substitute material, not only requires the addition of a large amount of AE (Air entraining and water reducing agent) water reducing agent in securing the same slump, but also leads to problems of performance degradation such as durability degradation.

When fly ash is added to concrete, it provides desirable properties of cement. However, since unburned carbon in fly ash may not be sufficiently air-incorporated in concrete, a surfactant is used to control the amount of air in the concrete mixing and pouring process. It is added to the mixture to stabilize the air void system.

There is a need to provide an improved method and system for treating fly ash, which can overcome the difficulty of mixing the liquid treatment agent and the bulk fly ash as described above.

In addition, it is required to provide a uniform fly ash manufacturing method and system that does not require major changes to the current method of manufacturing and handling fly ash, and accordingly minimizes the investment cost involved in implementing the method. do.

In order to treat the fly ash, Korean Patent Registration No. 10-1801530 (coal ash treatment apparatus and coal ash treatment method using the same) collects exhaust gas discharged from a coal-fired power plant boiler and separates it into processed gas including ash and sulfur compounds. A method of preparing sulfuric acid using the separated sulfur compound, making a mixture by contacting the prepared sulfuric acid and ash, and drying the separated sludge and extract by separating the sludge and extract from the mixture. A technique for treating unburned carbon powder and a technique for removing a glassy film coated on the surface are not mentioned.

In Korean Patent Publication No. 10-1547959 (Method for recovering unburned carbon from bottom ash by using the corona discharge electrostatic screening method), unburned bottom ash that is buried in coal ash generated after coal combustion in a thermal power plant is recycled as construction material, etc. The collected carbon is recovered and particle size separated, crushing and suspended impurities are removed to improve the screening efficiency, and a sieving operation is performed to concentrate the unburned carbon content, and a magnetic field of 2000 gauss is applied to the bottom ash enriched with unburned carbon. It is a technology that separates iron and recovers unburnt carbon in batam ash in the corona discharge electrostatic screening step from the bottom ash from which iron is separated.This technology cannot remove the vitreous film of batam ash particles.

In Korean Patent Publication No. 10-1514124 (Method to Remove Unburned Carbon from Fly Ash Using Plasma), after 1.2 g of fly ash is dispersed in the chamber during the plasma treatment process, oxygen (O ₂ ), water vapor (H ₂ O), oxygen And an oxidizing agent such as a mixed fluid of water vapor (O ₂ + H ₂ O) is added, the internal pressure of the chamber is reduced to 0.5 torr, heated to 150 degrees Celsius, and treated with lazma to remove less than 1% of fly ash. The technology has the problem of decompressing the interior of the chamber to 0.5torr, the point that the oxidizing agent is constantly consumed, and the glassy film on the surface of the fly ash particle cannot be removed, and the device is complicated and the investment and maintenance costs are high to increase the size.

As discussed above, the fly ash treatment technology recovered from the coal gas burned during the process in the conventional thermal power plant has a lack of treatment efficiency due to the above-described problems, and is treated with a large capacity while ensuring stability and durability. It is a situation in which a specific alternative is not presented below.

The high voltage generated by the DC DC power supply 341 is applied to the + electrode 342 and the-electrode 343 having different polarities to form an electric field between the electrodes 342 and 343 and charged at the injection port 335 to fall. When the fly ash particles pass between the two electrodes 342, 343, the unburned electrode 342 receives an electrostatic attraction according to the charged polarity (+, -). Particles such as carbon (C), alumina (Al ₂ O ₃ ), silicon dioxide (SiO ₂ ), and copper oxide (CuO) are attached to the + electrode 342 due to a negative charge during the electron exchange process, and- Particles such as calcium oxide (CaO) on the electrode 343 move to the (-) electrode 343 and attach it to the (-) electrode 343 by carrying a positive charge in the process of exchanging electrons, and then turn on-off power using a microcomputer in the control panel.

When the first cylinder 411 rotates, in the passage 402 formed between the main cylinder 401 and the first cylinder 411, the fluid (fly ash, air, fluorine compound, water vapor) located on the first cylinder 411 side A mixture of) has a direction to go out in the direction of the main cylinder 401 by centrifugal force, and due to this, the fluid becomes unstable, and a pair of rings that are regularly rotated in opposite directions along the first cylinder (rotation shaft) 411 are arranged. Vortex of the form. This is called the Taylor or Quette-Taylor vortex.

The vertical section of the first cylinder 411 is an oval, and the main cylinder 401 has a circular shape, but the cylindrical body 401 and the elliptical cylindrical first cylinder 411 have a central axis (vertical axis). Since it is arranged concentrically, while the first cylinder 411 is rotating, the main cylinder 401 is the distance D between the first cylinder 411 and the main cylinder 401, that is, the long side of the first cylinder 411 The distance between the end and the inner surface of the main cylinder 401 and the distance between the short side end of the first cylinder 411 and the inner surface of the main cylinder 401 do not change over time and become constant. In addition, the rotation of the first cylinder 411 is connected to the second cylinder 412 and the flange 413d, the first spur gear engaged with the second spur gear 413b fixed to one side of the second cylinder 412 (413a) Since the rotation is the same as the number of revolutions, the linear velocity V of the long side end and the short side end of the first cylinder 411 is constant. Therefore, even when the situation in the passage 402 elapses, the linear velocity V does not change and becomes constant, and the vortex is generated only by the rotation of the first cylinder 411 relative to the main cylinder 401. Has a limit to In order to improve this problem, it is composed of a body cylinder 401 and a first cylinder 411 that share the longitudinal axes 411 and 412 together, but between the body cylinder 401 and the first cylinder 411, a blank is formed to form a fluid passage. The body cylinder 401 has a circular cross section perpendicular to the longitudinal axis of the first cylinder 411 and the second cylinder 412, and the first cylinder 411 is on the longitudinal axis. The vertical cross section has an elliptical shape, and the rotation of the first cylinder 411 per minute to increase the relative rotational motion of the main cylinder 401 and the first cylinder 411 made with the vertical axes 411 and 412 as rotation axes In order to increase the number (RPM), the number of revolutions (RPM) of the motor 4413 is adjusted to the appropriate number of revolutions (RPM) selected through field tests, or the second driving motor 407 is driven and the number of revolutions (RPM) By adjusting the rotation speed of the main body cylinder 401, the appropriate rotation speed (RPM) selected through a field test is adjusted, or the rotation directions of the main body cylinder 401 and the first cylinder 411 are rotated opposite to each other, and the main body In order to increase the number of revolutions per minute (RPM) of the cylinder 401 and the first cylinder 411, the number of revolutions of the main body cylinder 401 was tested by adjusting the number of revolutions (RPM) of the second driving motor 407. The rotation speed of the first cylinder 411 is adjusted by adjusting the appropriate rotational speed (RPM) selected through or by adjusting the rotational speed (RPM) of the motor 4413 to the appropriate rotational speed (RPM) selected through field testing. A fly ash supply unit 420 for improving the flowability of the vortex in the passage 402 and supplying the fly ash is provided on an upper side of the main cylinder 401 and the rear end of the main cylinder 401 At the outlet 403 of the fly ash from which the vitreous film interlocked with the passage 402 is removed is provided.

In addition, in order to keep the vortex flow in the passage continuously active, the number of revolutions (RPM) of the first cylinder 411 and the second cylinder 412 connected by a flange is between 1 and 5000 (RPM). The inverter control circuit is attached to the first motor 413 so that the number of revolutions (RPM) of the second cylinder 412 is adjusted, and the number of revolutions (RPM) of the main body cylinder 401 is between 1 and 5000 (RPM). The inverter control circuit is attached to the second driving motor 407 so that the rotational speed is appropriate to adjust the rotational speed (RPM) of the main body cylinder 401.

In addition, when the main cylinder 401 rotates at a rotation speed selected in the range of 1 to 5000 (RPM) (e.g. 500 RPM or more) by the driving of the first motor 413, the main cylinder 401 is Turbulent flow is generated by the centrifugal force acting in the direction of the main cylinder 401 in the passage 402 formed between the cylinder 401 and the first cylinder 411, and the first cylinder 411 is driven second in a stopped state. When the main body cylinder 401 rotates at a rotation speed selected in the range of 1 to 5000 (RPM) by driving the motor 497 (e.g., 500 RPM or more), it is formed between the main body cylinder 401 and the first cylinder 411. Turbulent flow is generated by the centrifugal force acting in the direction of the first cylinder 411 in the passage 402. This turbulent flow is called a Taylor-Couette flow or Turbulent Tayler Voltex flow (TTVF), and the main cylinder 401 ) Is stopped and the first cylinder 411 is driven by the first motor 413, since the end cross section of the first cylinder is in the shape of an elliptical cylinder, that is, the difference in diameter between the long side and the short side of the first cylinder 413 When the rotational speed is 500RPM or less, the rotational speed of the first cylinder 411 receiving the rotational force of the first motor 413 is also 500RPM or less, so the flow of the fly ash in the passage 402 is irregular turbulent flow and sufficient centrifugal force is not generated. The number of rotations of the first motor 413 and the second driving motor 407 is not scattered (floating) in the passage 402 due to intermittent turbulent tayler volttex flow (TTVF) flow. In the passage 402, the number of revolutions is adjusted in the inverter, which is the number of revolutions for the first motor 413 and the second driving motor 407 respectively installed at 500 RPM or more so that the fly ash particles can be sufficiently scattered.

At the same time, the first driving motor 413 and the second driving motor 407 are driven to receive the rotational force of the first cylinder 411 and the second driving motor 407 to receive the rotational force of the first driving motor 413. When the main cylinder 401 is rotated in opposite directions, centrifugal forces acting in opposite directions collide with each other in the passage 402 formed between the main cylinder 401 and the first cylinder 411, resulting in eddy or spiral turbulent flow. It is formed to create an improved state of the Couette flow (Tayler-Couette flow or Turbulent Tayler Voltex flow (TTVF)).

In addition, arc discharge, corona discharge, glow discharge, spatter discharge can be applied to the high voltage discharge, but a preferred discharge method is arc discharge.

Arc discharge is a type of discharge that occurs in the air due to the potential difference between the positive electrode and the negative electrode when the positive electrode and the negative electrode are opposed. The voltage applied to the discharge electrode has a voltage of several volts or several tens of volts, and a discharge region capable of passing a current of several amperes or more. Say.

Unlike glow discharge or corona discharge, the characteristics of arc discharge are that the voltage at the start of discharge decreases and the current increases. In particular, hot electrons are emitted from the surfaces of the discharge electrodes 451 and 452 as a cathode by heating the discharge electrodes 451 and 452. There are characteristics.

In the arc discharge region, electrons move at high speed to obtain energy, and cause elastic collisions with other particles to transmit energy. At this time, the temperature of the particles rises, ionization of the particles and excitation to a high energy level occur through an inelastic collision process, causing an arc discharge to occur continuously.

In addition, during the process of arc discharge, electrons and hot electrons move at high speed between the discharge electrodes 451 and 452, and energy is obtained in the process of elastic collisions of particles that have obtained large energy per unit time, and at this time, high temperature heat is generated. do.

In addition, in the inelastic collision process that occurs after the elastic collision, ionization of particles and excitation to the energy level occur, and light (flame) is generated in the process of resolving the excitation.

In addition, the 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 conducting wire 454 and the connector 454a, and the discharge electrode 451 and the Discharge is initiated between the ground electrodes 452 to release charged particles such as electrons or ions, and hot electrons emitted from the discharge electrodes 451 and 452 heated at a high temperature, and between the discharge electrode 451 and the ground electrode 452 The work function value of silicon dioxide (SiO ₂ ), which is the main component of the film, is 5.0 eV, the work function value of calcium oxide (CaO) is 1.6 eV, the work function value of magnesium oxide (MgO) is 4.7 eV, and the work function value of barium oxide (BaO) is 1.1. Discharge electrodes 451 and 452 heated at high temperature with charged particles such as electrons or ions by generating electric field electron energy (IE, eV) greater than 5.0 eV of eV and alumina (Al ₂ O ₃ ) work function in the range of 5 eV to 5 KeV ), the glassy film coated on the surface of the fly ash particles can be removed in the process of elastic collision between the hot electrons emitted from the fly ash and the unreacted discretization within the field electron energy (IE, eV) range of 5eV to 5KeV. Fly by promoting chemical reaction with fluorine compounds of silicon (SiO ₂ ), calcium oxide (CaO), barium oxide (BaO), magnesium oxide (MgO) and aluminum (Al ₂ O ₃ ) and hydrolysis reaction with water vapor. It improves the removal efficiency of the glassy film coated on the ash particle surface.

The high voltage generator 453 of the discharging unit 440 is 12V or more when the input voltage is direct current (DC) power, and 110V or more when the AC power source is, and the output voltage is alternating current and that of direct current (DC) power. In the case of (AC) power, the output voltage selected in consideration of the removal performance of the glassy film coated on the surface of the fly ash particles in the same range of 1KV to 50KV may be selected and output from the high voltage generator 453.

Accordingly, one of the methods for improving the efficiency of removing the glassy film in the present invention is the main body cylinder 401 having the discharge electrode 451 or the ground electrode 452 installed on the inner surface, and the discharge electrode 451 or the ground electrode ( The high voltage generated by the high voltage generator 453 in the passage 402 formed between the first cylinders 411 on which the 452 is installed is applied to the discharge electrode 451 and the ground electrode 452 through the conducting wire 454 to form two discharge electrodes. When discharging is started between (451, 452), since the shape of the first cylinder 411 in the passage 402 is a cylinder having an elliptical cross section, the separation distance from the main cylinder 401 is the long side of the first cylinder 411 When the separation distance is small, the high voltage discharge starts uniformly, but in the case of the short side, since the separation distance is relatively larger than the long side, irregular discharge starts. In addition, a uniform high electric field region cannot be maintained in the passage 402 due to a difference in the spacing of the discharge electrode 451 and the ground electrode 452 provided on the body cylinder 401 and the outer surface of the first cylinder. To solve this problem raised, in order to create a flow of fly ash mixed with air, fluorine compounds, and water vapor in the passage 402 into a state of Taylor-Couette flow or Turbulent Tayler Voltex flow (TTVF). A fourth spur gear 409 installed on the lower circumferential surface of the body cylinder 401 engaged with the third spur gear 408 by driving the second driving motor 407 to rotate the third spur gear 408 connected to the shaft The first spur gear (413a) connected to the shaft by transmitting the rotational force to the main body cylinder clockwise or counterclockwise at a rotation speed (RPM) selected in the range of 10 to 5000 RPM while simultaneously driving the first motor 413 Is rotated, and a rotational force is transmitted to the second spur gear 413b installed on the circumferential surface of one side of the second cylinder 412 connected to the flange installed on the upper surface of the first cylinder 411 The first cylinder 411 connected to is rotated in a direction opposite or in the same direction as the rotation direction of the main cylinder 401 so that uniform discharge in the passage 402 is started.

In addition, when the main body cylinder 401 is stopped and the first cylinder 411 is driven by the first motor 413, the end section of the first cylinder is in the shape of an elliptical cylinder, that is, the difference in diameter between the long side and the short side of the ellipse 1 When the number of rotations of the motor 413 is 500 RPM or less, the number of rotations of the first cylinder 411 that receives the rotational force of the first motor 413 is also 500 RPM or less, and the flow of fly ash in the passage 402 is irregular turbulent flow. And since sufficient centrifugal force is not generated, the flow of Turbulent Tayler Voltex flow (TTVF) intermittently causes fly ash with a specific gravity of 2.15 or more to not sufficiently scatter (float) in the passage 402, so the discharge electrode 451 and the ground electrode 452 Fly ash in the passage 402 when the removal form of the glassy film coated on the fly ash particles in the high electric field electron energy band formed by the high voltage discharge is not good, and the rotation speed of the first motor 413 is 500 RPM or more. The flow of is a good Turbulent Tayler Voltex flow (TTVF) flow by generating good turbulent flow and sufficient centrifugal force, and fly ash with a specific gravity of 2.15 or more is scattered (floated) well in the passage 402, and the discharge electrode 451 and the ground electrode Removal of the glassy film coated on the fly ash particles in the high electric field electron energy band formed by the high voltage discharge at 452 is good, and the third spur gear 408 connected to the shaft by driving the second driving motor 407 Is rotated, and the rotational force is transmitted to the fourth spur gear 409 installed on the lower circumferential surface of the body cylinder 401 engaged with the third spur gear 408 to rotate the body cylinder 401 in a clockwise or counterclockwise direction. The rotational direction of the main body cylinder 401 by rotating at least 500RPM and receiving rotational force from the first spur gear 413a connected to the shaft to the second spur gear 413b with the rotational speed of the first motor 413 at 500RPM or more When rotated counterclockwise or clockwise, which is the opposite direction, the flow of fly ash particles in the passage 402 is wavelike vortex, spiral turbulence, and useful. The stone flows, and an irregular and strong centrifugal force is applied to maintain a more improved Turbulent Tayler Voltex flow (TTVF), and the flow of fly ash particles in the passage 402 is very good, so the discharge electrode 451 and the ground electrode 452 ), the glassy film coated on the fly ash particles in the high electric field electron energy band formed by the high voltage discharge is very well removed, and the removal time is shortened to increase the throughput per unit time. In addition, the body cylinder 401 and the first cylinder 411 are rotated in opposite directions, but even if the rotational speed of the first cylinder 411 is less than the speed of the body cylinder 401, the flow of fly ash in the passage 402 is It is able to maintain good Turbulent Tayler Voltex flow (TTVF) flow by receiving considerable centrifugal force.

In order to efficiently remove the vitreous film coated on the surface of fly ash particles by creating various patterns of Turbulent Tayler Voltex flow (TTVF) flow in the passage 402 formed between the main cylinder 401 and the first cylinder 411 The first motor 413 and the second driving motor 407 must be three-phase motors capable of forward rotation and reverse rotation, and a control circuit such as an inverter capable of adjusting the number of revolutions (RPM) is programmed in the control circuit of the control panel 600. Is entered.

The composition of anthracite used as a boiler fuel for coal-fired power plants is largely composed of combustible materials such as fixed carbon and volatile matter, and non-combustible materials such as ash and moisture.

As for the ash, 1 g of a humidity sample is taken from room temperature to 500 degrees Celsius for 60 minutes, 500 degrees Celsius for 60 minutes, 500 to 15 degrees Celsius, 30 minutes to 60 minutes, and 815 ± 10 degrees Celsius. It refers to the residue after heating and burning until the amount is converted, that is, the incombustible residue left after the coal is completely burned. Ash collected after anthracite is burned in the boiler of a coal-fired power plant is silicon dioxide (SiO ₂ ), aluminum oxide (Al ₂ O ₃ ), hematite (Fe ₂ O ₃ ), calcium oxide (CaO), and potassium oxide (K _{2 ).} O), sulfur trioxide (SO ₃ ), magnesium oxide (MgO), phosphorus pentoxide (P ₂ O ₅ ), titanium dioxide (TiO ₂ ) and unburned carbon powder (C), and the main component of the glassy film surrounding fly ash particles Is silicon dioxide (SiO ₂ ). Vitreous film, that is, glass is characterized by strong brittleness (a property that is broken by impact), and when heated, a certain melting point (melting point) is not visible, and its viscosity gradually decreases to transition to a liquid state. Although the tensile strength is small and the compressive strength is large, the actual value of the mechanical strength is inevitable inside the glass because the actual value is melted at a high temperature inside the boiler and then exhausted and flawed or rapidly cooled on the surface during post-treatment (vibration). Deformation (strain) occurs and falls significantly below the theoretically estimated value. The electrical conductivity increases as the soft glass (Na ₂ O) component increases or the temperature increases, and the electrical resistance decreases. The erosion of chemicals reacts very slowly with hydrochloric acid (Hcl) and sulfuric acid (H ₂ SO ₄ ), more reacts with alkalis such as sodium hydroxide (NaOH), and more with fluorine compounds such as hydrogen fluoride (HF).

In order to efficiently remove the glassy film surrounding the surface of the fly ash particles in consideration of the mechanical, chemical, and electrical properties of the glass described above, it is necessary to form a higher electric field energy band between the discharge electrodes 451 and 452, and It is necessary to increase the electrical conductivity of the glass by increasing the elastic collision strength with the fly ash particles due to acceleration and maintaining the temperature of the passage space formed between the main cylinder 401 and the first cylinder 411 at a high temperature. During the time, fluorine compounds and water vapor are sprayed onto the incoming fly ash and removed by chemical reaction and hydrolysis reaction with the main constituent substances of the glassy film surrounding the surface of the fly ash particles. As the glassy film on the surface of the fly ash is removed sufficiently, it is possible to solve the problem of the latent hydraulic property that cannot react with water in an integrated manner when the treated fly ash is recycled as a cement substitute, and the compressive strength can be increased when placing concrete. In order to further improve the removal efficiency of the glassy film coated on the particle surface, a high voltage is applied to the discharge electrode 451 and the ground electrode 452 to form a higher electric field energy band between the discharge electrodes 451 and 452. The input and output voltage of the power supply 453 is AC voltage (AC), the voltage is 110V or higher, the frequency is 60Hz or higher, the DC voltage (DC) is 12V or higher, and the output voltage is AC voltage (AC) and DC In the case of voltage (DC), a voltage value suitable for the field conditions and throughput is selected in the range of 1KV to 500KV, and for the frequency value, an AC voltage (AC) is selected in the range of 60Hz to 50KHz to suit the field conditions and throughput.

It is applied to 464, and as the output high-frequency current flows through the induction heating coil 464, a magnetic field is generated by the induction heating coil 464, and the generated magnetic field penetrates the main body cylinder 401, and this magnetic field The induction current flows in the body cylinder 401 of the skin depth that penetrated this, and joule heating is generated, and heat is supplied into the body cylinder 401 in the form of heat conduction. Fly ash particles passing through the passage formed between the 401 and the first cylinder 411 and the discharge electrodes 451 and 452 installed in the main cylinder 401 and the first cylinder 411 are heated to improve discharge efficiency and discharge electrode By activating the charge and hot electrons generated in (451, 452), the elastic collision strength between the fly ash particles and the charge and hot electrons is strengthened, and the magnetic field generated in the induction heating coil 464 extends the residence time of the charge and hot electrons. It further improves the glassy film removal efficiency by increasing the number of elastic collisions between fly ash particles and electric charges and hot electrons.
