Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses fossil fuels such as kerosene and heavy oil, synthetic fuels, etc. as main fuels, and ionizes hydrocarbon flames produced by combustion of these fuels to produce ordinary combustion flames (medium). Ion flame generator that generates an ion flame that has a higher heat than that of a flame). It can be used as an ion source for an apparatus that uses various ions such as a beam processing apparatus.

[0002]

2. Description of the Related Art Conventionally, as an ion flame generator for generating an ion flame from a fuel such as kerosene, there has been an ion burner used in an incinerator. 12 and 13 show an example of an incinerator using this ion burner, which has the following structure.

In this incinerator, a neutral flame chamber D and a quasi-plasma (quasi-ion) flame chamber are vertically arranged inside a main body A of a castable refractory made of a tubular material through grate B and C. E, a plasma (ion) flame chamber F is formed, three kerosene burners G are attached to the furnace wall of the ion flame chamber F, and a flame contact ionizing material H is formed at the tip of the kerosene burner G in the ion flame chamber F. Things are arranged, and the electromagnetic coil I is arranged on the furnace wall surface of the portion of the kerosene burner G where the flame hits. Here, the kerosene burner G, the flame contact ionization material H, and the electromagnetic coil I constitute an ion burner. In this incinerator, a high-frequency magnetic field (for example, a magnetic flux density of 10,000 or more and a frequency of 20 to 5 is applied by applying a pulse current or the like to the electromagnetic coil I.
When a high frequency magnetic field of about 0 MHz) is generated, the flame contact ionization material H is activated by the high frequency magnetic field, and an energy application action is brought to the flame contact ionization material H, and the kerosene burner that touches the flame contact ionization material H The combustion flame (hydrocarbon flame) of G is ionized (converted into plasma) and becomes an ion flame. This ion flame has a large number of ions in the ion flame chamber F, but in the quasi-ion chamber E the number of ions decreases and becomes a quasi-ion flame, and in the neutral flame chamber D it becomes a normal neutral flame. In this incinerator, when an object to be treated such as dust is put into the dust inlet J, it is dried in the neutral flame chamber D,
It is burned and gradually melted while falling in the quasi-ion flame chamber E and the ion flame chamber F, and is discharged as a melt from the discharge port K.

By the way, there is an ion flame state in which valence particles (carbon ions, hydrogen ions, oxygen ions, etc.) are present even in a hydrocarbon flame produced by normal combustion, but the number of generated ions is small, In the absence of a magnetic field, the ions immediately recombine to generate H2O, CO2, etc.,
It becomes a state of neutral flame. At the stage of transition from an ion flame to a neutral flame, a recombination reaction having an endothermic action occurs and heat is taken from the flame, so that the neutral flame has a reduced amount of energy as compared with the ion flame. For example, it is said that kerosene has an energy of about 8000K calories per liter, and the calorie released by the atomic dissociation reaction exceeds 10,000K calories, but in normal combustion, the ion flame state is extremely short-lived. Therefore, the high temperature could not be generated because the neutral flame was immediately transferred.

However, in the incinerator shown in FIGS. 12 and 13, a large number of ions can be generated by the aid of the flame contact ionizing material H to form an ion flame, and the generated ions can be recombined with each other by the high frequency magnetic field of the electromagnetic coil I. Therefore, the ion flame state can be maintained for a relatively long time, and the temperature inside the furnace can be set to 3000 ° C. or higher.

The flame contact ionizing material H used in the incinerator is produced by crystallizing a composition containing a photoactive substance and a magnetic material in an oxidizing atmosphere. The photoactive substance is a simple substance such as selenium, cadmium, titanium, lithium, barium, or thallium, or an oxide thereof, a sulfide, a compound such as a halide, and as a magnetic substance, a ferromagnetic substance (iron, nickel, Cobalt and its compounds, etc.) and paramagnetic materials (manganese, aluminum,
Tin and its compounds), diamagnetic materials (bismuth, phosphorus,
Copper, calcium, and their compounds).

[0007]

The ion burner in the incinerator can generate a much higher temperature than the kerosene burner G alone, which normally burns fossil fuels, and the incinerator can reach a high temperature of 3000 degrees or more. However, there were the following problems. 1. The flame contact ionizer H alone cannot generate a high temperature ion flame containing a large amount of ions. 2. Since cations and anions are mixed in the generated ion flame, the recombination of both ions cannot be prevented, and a neutral flame is likely to be formed. 3. From the above, the ion flame cannot be heated to a temperature exceeding 4000 degrees.

An object of the present invention is to produce a more powerful ion flame at a higher temperature, and a breeder type ion flame generator which can be used as various propulsion sources and ion sources as well as heat sources such as incinerators. To provide.

[Example 1 of use] An example of an incinerator using the above breeding ion flame generator will be described with reference to Figs. In the incinerator shown in FIG. 1, a substantially cylindrical incinerator body 1 is installed on a pedestal 10, and an ion flame generator 2 having an ion breeder 4 added around the incinerator body 1, that is, Four breeder-type ion flame generators are arranged radially. A smoke exhaust pipe 11 is provided in the upper center of the incinerator body 1, and four heat resistant pipes 3 are provided so as to surround the smoke exhaust pipe 11. The outside of the incinerator body 1 is covered with a magnetically shielded iron plate, and thus an iron casing (outer casing) 13 is provided.

The incinerator body 1 is made of a castable refractory material that can withstand a high temperature of about 4500 degrees, that is, a refractory material in which a refractory aggregate and a hydraulic agent such as alumina cement or phosphoric acid are mixed. An inner casing 14 is provided by coating the outer surface of the bull refractory with an iron plate. The incinerator body 1 may be made of graphite or other refractory material.

As shown in FIG. 8, the heat resistant pipe 3 is
It is a graphite pipe 25 obtained by molding and compressing a graphite material into a pipe shape, and then firing it. An oxide film 26 is formed on the outer surface of the graphite pipe 25. The graphite pipe 25 is electrically conductive,
The negative pole of the power supply device 27 and the positive pole of the iron inner casing 14 of the incinerator main body 1 are connected to each other. Power supply 2
7 is voltage 15000-30000V, current 20-50
A direct current voltage of mA is generated, and the direct current voltage can set the graphite pipe 25 to a negative potential. Graphite itself is a highly heat resistant material having a melting point of about 4500 degrees, but it is oxidized at about 1500 degrees in an air (oxygen) atmosphere and deteriorates immediately. However, by forming the oxide film 26 on the graphite pipe 25 and setting the graphite pipe 25 at a negative potential, the binding of oxygen ions (anions) that promote oxidation is prevented, and the temperature is kept at about 4000 degrees Celsius for a long time. It can be used.

As shown in FIG. 2, the heat-resistant pipe 3 is provided inside the incinerator body 1 and has two upper and lower graphite grate plates 1.
The heat resistant pipes 3 are supported by 5 and 16, and are arranged in front of the ion flame generator 2.
The heat-resistant pipe 3 has its upper end piped to a dust input hopper 17 at the upper part of the incinerator body 1, and has its lower end passed into a melt reservoir 18 at the bottom of the incinerator body 1. The object to be treated, which has been put into the dust input hopper 17, falls through the heat resistant pipe 3 and is accumulated as a melt in the melt reservoir 18 of the incinerator body 1.

The upper ones of the grate plates 15 and 16 are arranged above the mounting position of the ion flame generating device 2, and the lower ones are arranged below the mounting position of the ion flame generating device 2, respectively. The injection flame (positive ion flame) of the ion flame generator 2 is designed to be contained in the space between the first and second grate plates 15 and 16. However, this cation flame is confined in a donut shape inside the incinerator body 1 by a high-frequency magnetic field described later formed in the furnace, and does not touch the grate plates 15 and 16 or the furnace wall.

The exhaust tube 11 is made of the same castable refractory material as the incinerator body 1 and is formed in a tubular shape so that smoke and heat generated in the furnace can be exhausted to the outside. This exhaust stack 11
Is connected to the exhaust gas purification device group of FIG. At the center of the bottom of the incinerator body 1, a tubular melting and extracting tube 12 is provided, and like the exhaust tube 11, it is made of castable refractory. An opening / closing shutter 19 is provided at the tip of the melting and taking-out cylinder 12, and the shutter 19 is driven to open / close by a driving device (not shown). When the melt reservoir 18 is filled with the melt, the melt is automatically opened to melt the melt. Discharge and close automatically when the melt is discharged and emptied.

A water cooling jacket 20 is attached to the outer wall of the melt reservoir 18 of the incinerator body 1, and a high frequency coil 21 is attached to the outer periphery thereof. The high-frequency magnetic field generated from the high-frequency coil 21 heats the melt in the melt reservoir 18 to prevent the melt from solidifying, and enables smooth discharge from the melt-discharging cylinder 12.

The outer casing 13 that covers the outside of the incinerator body 1 is provided with four hot air recovery pipes 22 as shown in FIG. 1, and the ends of each hot air recovery pipe 22 are connected to the corresponding ion flame generator 2. I am doing it. The hot air recovery pipe 22 recovers the high temperature air heated by the radiant heat from the incinerator body 1 and sends the high temperature air to the ion flame generator 2 to reuse the heat, thereby increasing the energy efficiency of the incinerator. It is a thing.

The ion flame generator 2 is an incinerator body 1
Four of them are attached to the outer circumference in a cross shape (radially) so that two of them are opposed to each other. By arranging the ion flame generators 2 in a cross shape, high combustion noises due to explosive combustion (combustion of 13 to 15 m / s) emitted from the respective devices 2 collide with each other to cancel out sound waves and collide with sound waves. The sound can be reduced by the Doppler effect caused by. Further, by arranging the ion flame generating devices 2 radially at equal intervals, the high frequency magnetic field generated from the ion multiplying device 4 of each device 2 can be shaped into a magnetic field necessary for confinement of the tokamak method. That is, the positive ion flame injected from the ion flame generator 2 is trapped by the forming magnetic field and can be confined in a donut shape in the incinerator body 1. The magnetic field of this tokamak system concentrates the cation flame, which is highly corrosive at high temperature, only in the heat-resistant pipe 3 so that it can be effectively incinerated, and the inner wall of the incinerator body 1 and the grate plates 15, 16 etc. Protects the furnace from being hit.

The exhaust gas purification device group shown in FIG. 9 includes an exhaust gas cooling tank 90, a cooling tower 91, a desalination device (desalination tank) 92, a desulfurization device (desulfurization tank) 93, a denitration device (denitrification tank) 94, It consists of an aquarium 95. The high temperature harmful gas exhausted from the exhaust pipe 11 of the incinerator body 1 is cooled in the exhaust gas cooling tank 90, chloride is removed in the desalting tank 92, sulfide is removed in the desulfurization tank 93, and denitrification is performed. The nitrogen gas is removed in the tank 93 so that a low-temperature, pollution-free gas can be released into the atmosphere.

As shown in FIG. 9, the incinerator conveys the object to be treated, which is fed into the dust input hopper 17 at a high place, and the melt discharged from the melting and extracting tube 12 of the incinerator. A processing device 96 and the like for cooling, solidifying, crushing, and loading the dump truck or the like are provided.

Next, an operation example of the incinerator will be described below. When the ion flame generator 2 is started,
Burning kerosene up to about 800 degrees to generate a cation flame,
After that, when the temperature exceeds 1800 degrees, the metal powder mixed oil is burned to generate a cation flame, and when the temperature exceeds 2500 degrees, water is also burned to generate a strong cation flame exceeding 4000 degrees.

High-energy positive ion flames are jetted from the four ion flame generators 2 into the incinerator body 1, and the positive ion flames are confined in a donut shape, and the temperature inside the furnace reaches about 4000 to 4500 degrees. To be kept. In this state, when the objects to be treated are thrown into the dust input hopper 17, the objects to be treated are exposed to the cation flame in the furnace and its heat when they fall through the heat resistant pipe 3 and are instantly incinerated and melted. And is stored in the melt reservoir 18. The inside of the melt reservoir 18 is heated by the high frequency, and the melt is stored in a molten state without solidifying. Molten pool 18
When is filled with the melted material, the open / close shutter 19 is opened, and the discharged melted material is cooled and solidified by the device 96 in the subsequent stage, crushed into slag, and carried out by a truck or the like.

[Use Example 3] Another use example of the breeder type ion flame generator of the present invention in an incinerator will be described. It is also possible to provide only one ion flame generator 2 with the addition of the ion breeder 4, that is, a breeder type ion flame generator in the incinerator body 1. FIG. 10 is an example thereof, in which electromagnetic coils (strong magnetic field / electric field generator) 100 are separately provided at the facing position and the left and right positions of the ion flame generating device 2. This electromagnetic coil 1
00 has the same structure as that of the ion breeder 4 shown in FIG. 4, and the cylindrical main body 60 has a ring 61 of a non-magnetic metal (brass, stainless steel, etc.) and a ferromagnetic metal (iron, nickel,
Rings 62 of cobalt or the like) are alternately connected to form a tubular shape, and an electromagnetic coil 63 is attached to the outer circumference of each ferromagnetic metal ring 62.

In this incinerator, the positive ion flame injected into the incinerator body 1 is confined in a donut shape by the high frequency magnetic field generated by the ion breeder 4 and the high frequency magnetic field generated by the electromagnetic coil 100. Incinerator body 1
The heat-resistant pipe 3 provided in the furnace can be arranged close to the ion flame generator 2, but it can also be arranged in the center of the furnace as shown by an imaginary line in the figure.

The breeder-type ion flame generator of the present invention can be used not only as the heat source for the incinerator described above but also as a device requiring various high temperatures. For example, it can be used as an ion propulsion device, which is expected as a propulsion device for future rockets, and as an ion source for devices using various ion beams. In this case, for example, in a rocket engine, the turbo fan 30 of FIG. 3 is eliminated, the turbine 32 is enlarged instead, and the cooling system of the electromagnetic coil 63 in the ion breeder 4 of FIG. 4 is improved.
