Equipped with

At this time, the first combustion furnace 100 is connected to the waveguide 123 as a discharge pipe, and a plasma flame is generated in the plasma torch generation area (discharge space) within the discharge pipe by the M/W transmitted through the waveguide 123. occurs. At this time, plasma is generated within the discharge tube, and the introduced target material can be supplied to the discharge space and burned/oxidized/destructed/decomposed.

Additionally, the first combustion furnace 100 may use a tubular reactor made of a material such as quartz or glass. Here, the tubular reactor made of quartz is supported through a quartz holder 110.

In addition, the flame can be amplified using plasma fuel to increase the combustion temperature to a high level, making it possible to form a flame at a higher temperature than a regular gas burner. For this purpose, it is connected to the fuel injection unit and configured to inject fuel gas consisting of hydrocarbons (hydrocarbon-based fuel). Here, LPG, LNG, kerosene, etc. can be used as hydrocarbon fuels, and by generating plasma with low energy and injecting a certain amount of hydrocarbon fuel, a complete combustion reaction can proceed quickly. At this time, the operating temperature in the M/W plasma combustion oxidation system is 900 to 1,600°C, providing a very high combustion temperature. In this way, a large volume of target materials can be efficiently processed within a short period of time using flames generated by combustion of fuel gas made of hydrocarbons.

In addition, discharge gas, such as air, oxygen, steam, etc., may be injected into the discharge space of the first combustion furnace 100 through the target material injection portion or fuel injection portion, and a gas containing an oxidizing agent may be used as the discharge gas to produce 2000 It can provide a flame volume of ℃ or higher, reaching a temperature 50 times higher than that of arc plasma.

In addition, M/W of a preset frequency is supplied from the discharge space of the first combustion furnace 100 to generate plasma within the discharge space. For this purpose, the waveguide 123 and the microwave plasma generator are connected.

Here, the microwave plasma generator includes a M/W generator 101 that receives driving power supplied from the outside and generates M/W power, and a portion of the power generated through the M/W generator 101.

In addition, the intensity of the incident and reflected waves of the M/W output from the isolator 109 and the coupler 107 are adjusted to induce impedance matching, so that the electric field induced by the M/W is maximized within the discharge tube. It further includes a stove tuner (107). At this time, the two-way coupler 108 is used to receive the M/W generated by the M/W generator 101 and transfer it to the discharge tube while separating or combining the received M/W. In addition, the reflected power of M/W that is not absorbed in the reaction space of the discharge tube is attenuated. In addition, the M/W reflection force passing through the two-way coupler 108 reacts again in the discharge tube, and the remaining M/W that has not reacted in the discharge tube is absorbed through the 3-stub turner.

In addition, a M/W plasma burner control unit that controls the microwave plasma generator to control the M/W power provided to the first combustion furnace 100 through the waveguide is further provided. At this time, the M/W plasma burner control unit is a flowmeter box 103 that measures the flow rate, such as mass or volume, as the injection amount of the hydrocarbon-based fuel provided to the first combustion furnace 100 or the inflow amount of the target material. Wow, there is an indicator (112) with built-in status display LED and unit display LED to display the current operating status and status of data setting, modification, etc., and the status value displayed through the indicator is used to set M/W power or It is equipped with an MCU (114) that controls the injection amount of fuel or the inflow amount of target materials, and a power supply device (113) that applies driving power to the M/W generator. At this time, high voltage alternating current power may be applied to the power supply device 113.

In addition, the microwave plasma generator is equipped with a cooling fan 111 as a cooling device, and an oil compressor 104 and a chiller 105 are provided at the bottom of the chamber as cooling devices for the entire PTO plasma combustion oxidation system to form a reaction chamber. The temperature can be adjusted.

Referring to Figures 1 to 3, the primary function of the primary M/W plasma burner system is to burn and process the target material with high-temperature plasma, and the secondary gliding arc plasma burner system also oxidizes the target material through high-temperature plasma. It can be confirmed that the treatment is particularly effective in removing volatile organic compounds (VOCs).

In other words, the secondary gliding arc plasma burner system generates a high-quality (high temperature) flame and makes it easy to remove VOC through a high-temperature oxidation reaction. Here, “Volatile Organic Compounds (VOCs)” refers to a general term for liquid or gaseous organic compounds that easily evaporate into the atmosphere due to high vapor pressure among air pollutants.

The Gliding Arc plasma burner system is connected to the first combustion furnace 100 of the primary M/W plasma burner system and has a second combustion furnace into which the target material subjected to primary combustion treatment flows, and high-voltage power. An arc is formed through discharge in the second combustion furnace, and the generated plasma is convected by reactants and pushed to the rear end of the second combustion furnace. The target material subjected to primary combustion treatment flows into the second combustion furnace from the electrode. It is provided with a gliding arc burner unit that performs secondary plasma treatment through an oxidation reaction through the generated plasma flame.

The second combustion furnace is an arc reactor in which gliding arc discharge occurs. The operating temperature is high at 900 to 1,600°C, and a tubular reactor made of a material such as quartz or glass may be used. In addition, the second combustion furnace has an external housing made of an insulating material to prevent heat release to the outside, and a refractory material or fire prevention device 118 is provided at the lower part of the arc reactor to prevent fire due to arc or plasma flame. , a dust collector 117 that collects dust resulting from combustion or oxidation reaction may be further provided.

At this time, the power supply unit may be supplied with high-voltage AC power, and may measure the flow rate such as mass or volume as the injection amount of hydrocarbon-based fuel provided to the second combustion furnace or the inflow amount of the target material through the gliding arc flow meter 102. You can.

In addition, a gliding arc burner control unit may be further provided to control the M/W power provided to the second combustion furnace by controlling the gliding arc burner unit. At this time, the power supply device may be supplied with high-voltage AC power, and may be installed separately or integrated with the power supply unit 113 of the M/W plasma burner system. In addition, the gliding arc control unit, power supply, indicator, etc. can be integrated with the M/W plasma system and installed as a single unit.

Referring to FIG. 3A, the gliding arc (G.A.) burner unit includes a gliding arc electrode bar 121 into which fuel is injected through an internal hollow, and a first electrode bar holder 120 that supports the gliding arc electrode bar 121. and a second electrode bar holder 124 connected to the first electrode bar holder 120 and equipped with an external electrode and into which discharge gas is injected, and a gliding arc supporting the second electrode bar holder 124. A body, an internal electrode 125 connected to the distal end of the gliding arc electrode bar and located inside the second combustion furnace to generate a plasma flame 126, and an arc 127 that covers the internal electrode 125 and ) is provided with a third electrode bar holder that generates. At this time, the gliding arc burner unit is a small device, and when it is configured in plural, the heat treatment effect can be increased. In the present invention, a total of 12 gliding arc burner units can be formed with 3 module electrode bars, 2 each symmetrically on the left and right. In addition, the first to third electrode bar holders are preferably made of ceramic material with good heat resistance due to flame, etc.

Additionally, the gliding arc burner unit forms a swirl discharge through a rotating gliding arc discharge. That is, when a high voltage of alternating current is applied to the external electrode of the gliding arc burner unit and the other internal electrode, the power value increases and is converted to heat energy, thereby increasing the temperature. As a high temperature state is formed, the acceleration of electrons occurs due to the lowered density. occurs and discharge occurs.

At this time, if the plasma formed by a relatively large number of strong electrons is sufficiently ionized, discharge easily occurs.

Additionally, when the plasma escapes and discharge occurs again, a continuous discharge occurs where the discharge occurs directly at the plasma departure point rather than at the shortest distance from the electrode. In this process, a continuous discharge that occurs depending on the power supply value is formed at one end at the end of the internal electrode and at the other end at the inner wall of the external electrode, and as the power value increases, the plasma area expands.

Under this condition, high acceleration of electrons occurs in the arc line that increases in the longitudinal direction, and the generated arc plasma creates an environment for high temperature and oxygen active species generation. The generated arc plasma creates an environment of high temperature and oxygen active species generation, and can increase combustion efficiency through plasma chemical reaction with the injected fuel (LPG), thereby maximizing the effect of latent heat.

Referring to Figure 3b, the gliding arc burner system decomposes VOCs into CO ₂ and H ₂ O through a high-temperature oxidation reaction and the reaction heat can be recycled, confirming that it is effective in removing volatile organic compounds (VOCs). .

Then, after oxidation combustion reaction treatment by high-temperature combustion reaction, it is discharged to the gas outlet (OUT) through the gas transfer unit. During the discharge process, it passes through the photocatalyst beads 116 and the honeycomb-type hybrid composite catalyst system 115. Remaining unreacted odorous gases, non-decomposable substances, VOCs, and HAPs can be additionally removed.

As such, the principle of plasma combustion/oxidation reaction in the PTO system according to the first embodiment of the present invention can be summarized as follows.

In other words, the plasma combustion oxidation reaction principle is that when a high field of 10 kV/cm or more is applied between two discharge electrodes, the anode and the cathode, for an extremely short moment (within tens to hundreds of ns), a brush-like shape is generated by pulse corona discharge. A current channel is formed, which is called a streamer. High-energy electrons propagate between two electrodes at a speed of 10 ⁶ to 10 ⁷ cm/sec and collide with molecules in the electric field. In this way, molecules that collide with high-energy electrons are ionized and decomposed by high-temperature combustion oxidation into active free electrons.

In addition, the plasma burner forms a high-speed rotating flame, which can quickly increase the temperature in the combustion furnace. It is an oxidation combustion device in which plasma ions that destroy and decompose contaminants in the combustion gas are injected, and the air ratio is evenly distributed. Thus, an air supply distribution device that causes complete combustion may be further included.

Here, combustion/oxidation/destruction/decomposition is performed with PTO high-temperature plasma in the combustion furnace (discharge tube) of the M/W plasma burner and the gliding arc burner. In other words, odorous gases, non-decomposable substances, VOCs, and HAPs can be removed through the high-temperature combustion reaction while the combustion reaction and oxidation reaction proceed sequentially.

For example, PTO (Plasma Thermal Oxidation) odor reduction technology generates high-temperature plasma with low energy and can quickly proceed with a complete combustion reaction by injecting a certain amount of hydrocarbon fuel.

Additionally, the plasma flame can be amplified and the combustion furnace temperature can be increased to a higher temperature than that of a regular gas burner.

In addition, magnetron energy efficiency can be increased by more than 80%, M/W plasma transmission efficiency can be increased by more than 99%, and gliding arc transmission rate can be increased.

In addition, installation/operation costs are low, it has the effect of significantly reducing electricity costs, maintenance costs, and operating costs, and LPG, LNG, and kerosene can be selectively used.

This can maintain a high-temperature environment compared to existing RTOs, reduces plasma combustion effects and fuel costs due to the small amount of LPG used, and can be manufactured in a small size, reducing initial investment costs.

Referring to FIG. 4, after processing the oxidation combustion reaction through a high temperature combustion reaction through the PTO plasma combustion oxidation system according to the first embodiment, it passes through the photocatalyst beads 116 and the honeycomb type hybrid composite catalyst system 115. After post-processing the remaining target material, the target material is transferred to the dust collection system through the gas transfer unit.

Referring to FIG. 5, in the dust collection system, the target materials that are primary and secondary treated through the transfer pipe are filtered as they pass through the ceramic filter 200. At this time, the ceramic filter 200 is arranged as 12 filters of 3X4, has a multi-stage or multi-layer structure, enables multi-stage filtration, is compact, and boasts a high specific surface area.

Referring to FIG _. 6, looking at the internal structure _of the ceramic filter 200, a SiC coating layer is formed on the outer surface, and _{a MnO} Accordingly, the external SiC coating layer is a surface filtration layer that can collect and filter fine dust and _NO In addition, the internal composite catalyst coating layer uses Urea as a reducing agent as a catalyst support layer to provide high dust collection and removal efficiency through SCR catalytic reaction.

In addition, as it is made of ceramic material, it can be used at high temperatures above 800℃ and is a dust collection device capable of highly efficient dust collection.

In addition, it has excellent chemical resistance, is made of non-flammable materials, is easy to replace and inspect the filter, and has a long filter life. That is, the ceramic filters 200 are arranged in an array of 12 and each is fastened through the filter holder 204, making replacement and inspection of the filters easy. In addition, by using a separator with a built-in ceramic filter 200 and introducing it into the filter with a structure that can be backwashed, filtration capacity and processing efficiency can be maximized.

This ceramic filter 200 can filter fine dust particles (Dust), SOx, and NOx dust, and can even remove particles as large as PM25.

In addition, the dust extraction method is offline, so dust extraction efficiency can be maximized, and the dust collector 202 is connected to the bottom, and the dust collector can be easily separated and fastened through the ball valve 206. It is easy to collect and clean fine dust.

Additionally, the ceramic filter 200 can be cleaned periodically through the air spray bar 203, thereby improving dust collection efficiency. At this time, an automatic timer exhaustion function is possible through the barometer sensor 205.

At this time, the air distributor 201 checks the inspection cycle of the ceramic filter 200 through the barometer 205 and is linked to the air spray bar 203 to check the numerical value with an air pulse.

In the PTO plasma combustion oxidation system according to the second embodiment of the present invention, the target substances CO, NOx, SOx and VOCs emission concentration can be significantly reduced. Accordingly, it is a dry treatment device that is less dependent on the exhaust gas post-treatment device as the emission concentration of target substances is significantly low, but in the second embodiment, SOx and NOx reduction is possible by adding a ceramic PM dust collection system as an additional post-treatment filter system. This ceramic dust collection system can remove particles up to PM25 size by introducing a ceramic filter that can filter out fine particles, SOx, and NOx dust.
