Description

Gas furnace system for indirect heating of waste organic matter using microwave electromagnetic waves {Pyrolysis apparatus using microwave}

The present invention relates to a gasification furnace system of indirect heating of waste organic matter using microwave electromagnetic waves, and in particular, for ignition of a fixed bed gasifier for gasification of fuel with low reactivity, supply of additional combustible fuel for ignition through microwave irradiation It relates to a gas furnace system of indirect heating of waste organic matter using microwave electromagnetic waves that can directly ignite fuel with low reactivity rather than the necessary igniter.

A fixed bed gasifier (fixed bed gasifier) is a gasifier developed for the first time among various types of gasifiers, and there are several types of models including the Lurgi type developed in West Germany in 1934, and has already been put into practical use in many countries. In the case of a fixed bed gasifier, coal, waste, and biomass (hereinafter collectively referred to as raw material) pulverized to a size of 025-15 inches is charged at the top of the gasifier (more specifically, the gasifier's reactor) and then gravity It is dried and gasified as it descends by the Syngas generated through this process can be used for various purposes after being discharged to the outside of the gasifier and then subjected to additional treatment.

Gasification refers to a process in which a hydrocarbon-based material is partially oxidized and converted into a combustible gas mixture such as hydrogen, carbon monoxide and methane. Syngas through the refining process can then be applied to alternative natural gas (SNG), clean fuel (DME), ammonia (NH3), synthetic petroleum, and hydrogen production. One of the disadvantages of such a fixed bed gasifier is that it requires an additional igniter for ignition. When coal or biomass is used as a fuel for gasification in a conventional fixed bed gasifier, initial ignition is formed using a gas torch or oil burner while a combustible material (paper or biomass) is supplied to the inside of the reactor. . It takes a considerable amount of time for the internal temperature to rise above the reaction initiation temperature by igniting the upper part of the reactor and supplying heat to the lower part of the reactor.

The ignition condition of a general fuel top-fed fixed-bed gasifier is that a highly ignitable combustible material (paper, biomass, etc.) is first charged into the fixed bed reactor and then filled with a gas torch or a burner using additional combustible components. is ignited, and while continuously supplying a combustible material, it is heated until it reaches a temperature at which a fuel with low ignitability such as coal can be ignited. Thus, the supply of coal is gradually increased to operate up to a steady state condition. When the fixed bed gasifier is operated under these ignition conditions, it takes a long time to reach a steady state, the inside of the reactor may not be ignited uniformly, and an ignition port or a gas torch is additionally required to be installed in the reactor.

On the other hand, when a microwave for ignition is installed, there is no need to input a combustible material, a gas torch or a burner using an additional combustible component is not required. Driving is possible.

The eco-friendly waste pyrolysis and combustion device using the microwave igniter of the present invention is basically a pyrolysis device 100, a burning unit 200, a combustion unit 300, a boiler 400, and a diffuse reflection induction device 1000. and a temporary waste storage unit 2000 and a waste supply unit 100a.

The pyrolysis device 100 for waste according to the present invention forms a carbonization or pyrolysis space for carbonizing and thermally decomposing waste. A microwave oscillator 120 for heating that is installed at the middle point outside the housing of the heating furnace body 110 and emits microwaves into the heating furnace body to heat waste existing inside the heating furnace body; A microwave oscillator 130 for ignition that is installed at the lower end of the housing and emits microwaves into the body of the heating furnace, but exposes microwaves for a long time to ignite the waste existing inside the body of the heating furnace to generate a spark, and the microwave for ignition A gas passage 140 for collecting and discharging the gas of the low-temperature pyrolyzed waste by the oscillator to the outside, and for igniting the waste by receiving electromagnetic waves from the microwave oscillator and receiving the electromagnetic wave from the microwave oscillator located on the bottom surface of the body. It is made to include an electromagnetic wave heating element (160).

The electromagnetic wave heating element 160 may be formed in various shapes, but a hollow part 161 is formed in the middle to allow air to pass therethrough.

In addition, the electromagnetic wave heating element 160 is molded by mixing silicon carbide (SiC), graphite and loess, silicon carbide 35-40% by weight, graphite 30-35% by weight and ocher 25-30% by weight by mixing It is molded at high temperature and high pressure so that loess can be turned into ceramic.

When a large amount of silicon carbide is contained in the electromagnetic wave heating element 160 by weight or more, the brittleness of the electromagnetic wave heating element 160 is increased, and when it is included in less than the weight%, the amount of heat is insufficient.

When the electromagnetic wave heating element 160 contains more than or less than the numerically limited weight percent of graphite, there is no particular change, but since it affects the weight percent of other materials, the numerical limitation of the present invention is appropriate.

When the electromagnetic wave heating element 160 contains more than the numerically limited loess by weight or more, the brittleness of the electromagnetic heating element 160 is increased, the calorific value is also insufficient. will also fall

The graphite is a material that is heat-treated by reinforcing carbon fiber, and can increase the durability of the electromagnetic wave heating element 160, loess has strong heat resistance, and silicon carbide responds to electromagnetic waves (microwave or microwave).

The silicon molecules of the silicon carbide vibrate in response to electromagnetic waves, and continuously generate strong heat while rubbing with the loess (ceramic) molecules, and this heat exchanges heat with the air in contact with the outer wall of the electromagnetic wave heating element 160 to give air provide heat

In addition, silicon carbide fibers are mounted on the upper surface of the body of the electromagnetic wave heating element in the form of a wire mesh, and when microwaves are concentrated on the silicon carbide fibers, high-temperature heat is generated, so that the ignition of waste can be easily generated.

That is, high-temperature heat is applied to the waste by using the electromagnetic wave heating element body, and the silicon carbide fiber is in direct contact with the waste to induce ignition.

In addition, a rubble waste storage unit 2000 installed on the lower side of the heating furnace body to temporarily store carbonized or pyrolyzed remnants decomposing waste, and carbonization or pyrolysis in the carbonization or pyrolysis space of the heating furnace body 110 and a waste supply unit 100a for supplying waste for the purpose.

The microwave oscillator 120 for heating is installed at an external end of the heating furnace body 110 . It is preferable that a plurality of microwave oscillators 120 for heating are installed on both sides of the heating furnace body 110 .

The heating microwave is defined as a microwave between 300 MHz and 300 GHz, and the heating microwave oscillator 120 for heating the waste inside the body 110 with the heating furnace oscillates a microwave of 245 GHz or more. It is preferable to use an oscillator that The microwave oscillator 120 for heating may be formed of a magnetron. A shielding gasket (not shown) is installed in the housing constituting the heating furnace body to prevent microwaves generated from the heating microwave oscillator 120 from leaking to areas other than the heating furnace body 120 . can be

Meanwhile, an auxiliary heating device or an auxiliary heat source may be further provided to heat the body 110 at a uniform angle with the heating furnace. The auxiliary heat source is possible as long as it does not interfere with the heat generated by the heating furnace body 110 and is not damaged by the heat generated from the heating furnace body 110 . For example, a heating wire may be used.

The ignition microwave 130 emits microwaves using a magnetron, but emits microwaves for a long time to ignite the waste, stops the microwave emission when the waste is ignited, and controls the oxygen supply to maintain the ignition state of the waste let it do

The carbonization or pyrolysis apparatus for waste according to the present invention configured as described above will be described in more detail for each component as follows.

The heating furnace body 110 forms a carbonization or pyrolysis space for carbonizing the waste 10 supplied from the waste supply unit 100a, and the waste 10 supplied from the waste supply unit 100a is transported. It has a tubular shape with a predetermined length so that it can be carbonized and pyrolyzed in the process.

The heating furnace body 110 may have an insulating space formed therein, and the insulating space may be filled with an insulating material, and it is natural that the insulating material should be able to withstand heat sufficiently.

The temporary waste storage unit 2000 is installed at the output end of the heating furnace body 110, and the remaining residue is temporarily stored after carbonization or thermal decomposition is completed.

And, the waste supply unit 100a may further include a crushing means for crushing and supplying the waste. In addition, in the case of waste plastics, a neutralizing agent input device for inputting a neutralizing agent (ca(OH)2) after pulverization may be further provided.

The operation of the carbonization and pyrolysis apparatus using microwaves according to the present invention configured as described above will be described as follows.

First, in order to carbonize various wastes, such as waste, that is, hospital infectious waste, animal rice, various PCB boards, waste wires such as communication lines, etc., waste for carbonization is supplied to a hopper. In this process, the waste is preferably pulverized to a predetermined size and supplied.

In this state, the inside of the main body 100 is heated by using the microwave oscillator 120 for heating.

At this time, since oxygen is not supplied to the pyrolysis space where the waste of the main body 110 is present, the heat is pyrolyzed in an anaerobic state.

On the other hand, if the waste enters the body of the heating furnace in a frozen state in winter, it must be heated after the thawing process.

That is, due to the nature of microwaves, the amount of microwave energy is not concentrated in the ice state and just passes through it, and the energy absorption is large in the water state. If it is heated, it will burn, and the unmelted part, on the other hand, is kept in a frozen state for a long time because there is not much absorption of microwaves.

In other words, when a microwave having a property of rapidly changing an electric field is applied to a liquid having a polarity, the liquid having a polarity quickly aligns along the direction of the electric field. When aligned in the direction of the electric field, thermal energy is generated by friction between adjacent molecules, so that wastes with moisture can be heated at a high speed.

However, when the frozen waste is continuously heated with the same output as that of general waste, a problem due to non-uniform heating of the target waste is pointed out.

In addition, since the heating point is formed in the state of a plurality of points rather than evenly heating the entire object due to the nature of the microwave, there is no problem because the whole is heated while the heating point is propagated to the surroundings in the liquid state. When thawing, it is not easy to propagate to the surroundings, so the heating point absorbs more heat than other parts, and only that part is heated at a faster rate than other parts, so it may burn.

This is because microwaves overlap and interfere with each other, so that the maximum and minimum points of radio waves exist. it will be heated

As a result, the microwave heating system has a characteristic of rapidly increasing the temperature of an object, so it is very efficient to heat a liquid, but has a problem in that it is difficult to thaw evenly in a solid state or a frozen object.

In order to solve this problem, the present invention sets the step-up voltage of the high-voltage transformer to 1600V - 1800V in the operating mode of thawing the frozen waste, and emits microwaves for 10 seconds to minimize partial heating, and does not emit for 10 seconds Intermittent system apply

That is, the voltage of a typical microwave is 2300V - 3000V, but in the present invention, by lowering the voltage to reduce the boosted voltage of the high-voltage transformer to 1600V - 1800V, even if the microwave provision time is increased, waste is ignited, and in addition, the microwave Even if overlap occurs, it is possible to prevent the waste from igniting by intermittently providing microwaves and to maintain only the heating state.

On the other hand, it is preferable that the microwaves are diffusely reflected as they are closer to the frozen waste to minimize overlapping of microwaves and to diffuse them widely.

That is, in the case of liquid waste or wet waste, even when microwaves are overlapped, the heated heat spreads to the side and uniform heating of the waste can be achieved. Therefore, the microwave is diffusely reflected to induce the microwave overlap to be minimized.

Looking at the technical configuration of the diffuse reflection inducing device 1000 of the present invention, a diffuse reflection induction support unit 1100, a T-shaped diffuse reflection induction unit 1200, a vertical bar 1300 for controlling diffuse reflection, and a motor unit 1400 for driving the vertical bar. is done

The diffuse reflection induction support unit 1100 is in the form of a vertical frame, and is vertically inserted and installed on the inner periphery of the body as a heating furnace.

The T-shaped diffuse reflection induction part 1200 is formed by combining a vertical bar 1210 and a horizontal type bar 1220, and is inserted and installed on the surface of the diffuse reflection induction support part 1100, and the vertical surface of the vertical bar 1210 And the microwave is diffusely reflected using the horizontal surface of the horizontal bar (1220).

The vertical bar 1300 for adjusting the diffuse reflection is slidingly coupled to the horizontal bar 1220 of the T-shaped diffuse reflection inducing part 1200, and the degree of diffuse reflection is adjusted by determining the degree of protrusion of the T-shaped diffuse reflection inducing part 1200 by an elevating operation. .

The motor unit 1400 for driving the vertical bar has one end coupled to the vertical bar 1300 for controlling the diffuse reflection, and it raises or lowers the vertical bar 1300 for controlling the diffuse reflection by forward and reverse rotation operations. When the vertical bar 1210 is inserted into the vertical bar 1300 for controlling diffused reflection, diffused reflection of microwaves is made only through the vertical surface of the vertical bar 1210, and when the descending operation is performed, the vertical bar 1210 is for controlling diffused reflection While protruding from the vertical bar 1300 , the diffuse reflection is simultaneously induced through the vertical surface of the vertical bar 1220 and the horizontal surface of the horizontal bar 1210 .

The operation of the present invention will be described below.

As a result, the T-shaped diffuse reflection inducing part 1100 uses only the vertical surface of the vertical bar 1210 to generate the diffused reflection of microwaves while overlapping, so that the liquid waste maintaining the temperature above the standard is heated to 80 to 90 degrees.

That is, if the temperature sensor 1000a is mounted inside the heat furnace body, and the control unit 1000b based on the measurement result of the temperature sensor, if the waste is a temperature higher than the standard, the microwave reflection concept is applied. The motor unit 1400 for driving the vertical bar is driven so that the heating phenomenon is strongly generated while overlapping, and the heating energy is spread to the materials located in the vicinity by the heating phenomenon generated while the microwaves are overlapped, and the waste material is discharged at a faster rate. of heating work.

On the other hand, when it is determined that the waste is in a frozen state as a result of the measurement of the temperature sensor 1000a, the control unit 1000b operates the motor unit 1400 for driving the vertical bar so that the vertical bar 1300 for adjusting the diffuse reflection is lowered. Then, both the vertical bar 1210 and the horizontal bar 1220 of the T-shaped diffuse reflection inducing unit 1100 come out, and diffuse reflection of microwaves is made through the vertical bar 1210 and the horizontal bar 1220, Accordingly, the thawing operation is performed evenly without overlapping microwaves. That is, the thawing operation is performed evenly without partially igniting the waste.

Thereafter, when it is determined that the defrosting operation is properly completed as a result of the reading of the temperature sensor 1000a, the control unit 1000b drives the vertical bar driving motor unit 1400 to raise the diffused reflection control vertical bar 1300, and thus the T-shaped When only the surface of the horizontal bar 1220 of the T-shaped diffuse reflection inducing part 1100 is exposed to the outside while the diffuse reflection induction unit 1100 is inserted into the diffuse reflection control vertical bar 1300, the microwaves are overlapped and reflected to heat the liquid waste. is optimized for

The odor intrusion prevention means 2040 is composed of a square panel 2041 and a weight 2045 extending from the end of the square panel, the first supporting wire mesh 2010 and the second supporting wire mesh 2020. While spanning the ends, it is in contact with the first supporting wire mesh 2010 and the second supporting wire mesh 2020 to block the smell of the rubble waste storage unit 2000 from rising through the inlet.

That is, the odor inflow prevention means 2040 installs a weight hanger 2042 and a weight 2045 through the extension line 2043, and when wastewater does not flow due to the presence of the weight 2045, the The first supporting wire mesh (2010) and the second supporting wire mesh (2020) are kept in close contact, and when wastewater flows from the heating furnace body, the wastewater square panel 2041 is pushed and the support hook 2044 is the center to keep the open state so as not to interfere with the flow of wastewater, and when the flow of wastewater is finished, it returns to its original state due to the role of the weight 2045, and serves to block the inflow of external odors.

When the third wire mesh for spacer 2030 is coupled, the folding angle of the first supporting wire mesh 2010 and the second supporting wire mesh 2020 is maintained, so that it is no longer unfolded or folded.

And, the voids of the third wire mesh for spacer 2030 are larger than the gaps of the first support wire mesh 2010 and the second support wire mesh 2020, so that small pollutants are the third wire mesh for spacers 2030 Guided to be placed on the first support wire mesh 2010 and the second support wire mesh 2020 through the.

In addition, the odor intrusion prevention means 2040 is installed while spanning the ends of the first supporting wire mesh 2010 and the second supporting wire mesh 2020, and when the wastewater does not flow from the body of the heating furnace, a weight 2045 ) due to the role of the wire mesh to prevent the odor of wastewater from flowing into the upper part of the temporary waste storage unit, and when wastewater flows downward from the body of the heat generating furnace, it flows while pushing the square panel 2041, resulting in a normal flow of wastewater This is induced When the flow of wastewater is finished, it returns to its original state due to the role of the weight 2045 and is in close contact with the wire mesh to block the inflow of odors.

Accordingly, in consideration of the width of the rubble waste storage unit, the first supporting wire mesh 2010 and the second supporting wire mesh 2020 are spread out, and then the distance is maintained with the third spacing agent wire mesh 2030 to maintain the first supporting wire mesh. (2010) and the second supporting wire mesh (2020) is prevented from being folded.

If the third wire mesh 2030 for spacer does not exist, the first support wire mesh 2010 and the second support wire mesh 2020 may be installed and then folded by an external impact, etc., then the rubble waste storage unit 2000 ), there is a problem of falling inside.
