Description

DEVICE OF DISSOLVEING HARMFULL GAS BY USING PLASMA}

The present invention is a device for decomposing harmful gases that are chemically stable and difficult to decompose to the human body, and more particularly, to a technique of generating plasma at atmospheric or atmospheric pressure to break or harmless the molecular rings of harmful gases. will be.

The air on earth is indispensable to the survival of our human beings and creatures, and it also plays a role in keeping the temperature on earth constant due to convection. The earth has the ability to purify itself physically, chemically, and biologically, and some air pollution is purged by the earth's midnight action.

However, since the twentieth century, as a result of rapid advances and developments in science and technology, population growth, urbanization and continuous industrial development, the self-regulating function caused by the natural ecological clean-up ability of the global ecosystem has sharply declined. Among the factors, air pollution has reached a level that threatens the natural survival of the ecosystem.

All components of the earth's ecosystems must be contained in an appropriate and harmonious manner, and if any one of them is contained in excess, especially if some of the substances in the atmosphere contain too much, Classified as dangerous air pollutant.

Such air pollutants are largely classified into organic gases (Gas), inorganic gases, and aerosols. In particular, organic gases are hydrocarbon-based materials such as olefins (Olefin) and paraffins, and inorganic. The gas is a substance such as carbon monoxide, nitrogen oxides, sulfides and the like.

Such pollutants are generated naturally or by human industrial activities, but if they are above the appropriate concentrations that can be naturally purified by the global ecosystem, they not only damage the ecosystem of humans and animals, but also humans. Will also damage property.

In one embodiment, the altitude of 11 Km to 15 Km above sea level due to the exposure of the freon gas (CFC: CF ₂ CL ₂ ), which is used as a refrigerant such as a refrigerator and an air conditioner, in the atmosphere, among the pollutants that destroy the global ecosystem. As a result, it flies from the sun and results in the destruction of the stratospheric ozone (O ₃ ) layer that functions to block ultraviolet rays harmful to the human body.

Therefore, since the ultraviolet rays from the sun reach too much on the surface of the earth, they have a drastic effect on the growth of animals and plants on the earth, and the ecosystem order is destroyed.

In order to prevent the destruction of the global environment, the Montreal Protocol on Substances That Destroy the Ozone Layer, which regulates the use and emission of the Freon (CFC) gas and the like, regulates the emission of carbon dioxide (CO ₂ ) gas. International efforts are underway, such as the International Warming Prevention Agreement.

As described above, in order to reduce the air pollutants that threaten the earth's ecosystem, so that the air pollutants are not generated fundamentally or pollutants which are by-products of urbanization, industrialization and human activities do not pollute the air on the earth. By purifying, it does not threaten the survival of humans and animals and plants.

According to the related art, the method for purifying Freon (CFC) gas, which is the above contaminant, uses an electromagnetic induction high frequency torch, and blows the Freon gas into a vapor plasma of about 10,000 degrees Celsius. By disposing, it is decomposing harmful chemicals that are stable or difficult to decompose, but there is a problem that cannot be put to practical use because there is no container that can withstand the temperature of 10,000 degrees Celsius in the structure of high frequency torch and the structure of continuous gas flow .

In addition, since the use of fossil fuels and exhaust gas from automobiles in factories and thermal power plants is reduced by using a reducing catalyst such as silver, there is a problem such as high cost.

The present invention breaks the molecular ring of nitrate compounds, sulfuric acid compounds, etc. contained in the Freon (CF ₂ CL ₂ ) gas that destroys the ozone layer, automobile exhaust gas, etc. It is an object to provide a device.

In order to achieve the above object, the present invention provides a frequency generator for generating a low frequency frequency signal, a bipolar pulse generator for generating a bipolar pulse signal, and a modulated output signal of the frequency generator and the bipolar pulse generator. A mixer, a pulse width controller for adjusting a width of a pulse signal modulated and output from the mixer, a pulse amplifier for amplifying a signal applied from the pulse width controller, and boosting by applying a commercial AC power, It consists of a power supply for controlling current and voltage to the power supply, a DC power supply for supplying the operating DC power of each functional unit by receiving commercial AC power, and a discharge tube for receiving the signal output from the pulse amplifier to the anode and the cathode. By using the plasma It features.

A power supply 60 for receiving a feedback and controlling the supply of voltage and current to output a signal of an appropriate voltage,

A DC power supply 70 receiving commercial AC power and supplying operation DC power of each functional unit;

The high voltage pulse signal output from the pulse amplifier 50 is applied to the anode 90 and the cathode 92, and the anode 90 and the cathode 92 are adapted to match the discharge start voltage of the gas supplied. It consists of a discharge tube 80 that can adjust the distance.

Hereinafter, an atmospheric pressure plasma generator using the pulse of the present invention having the above configuration will be described in detail with reference to the accompanying drawings.

The present invention generates a plasma at a normal atmospheric pressure (atmospheric pressure) such as freon (CF ₂ CL ₂ ) gas or nitrogen dioxide (NO ₂ ) harmless to the human body, and decomposes in a state compatible with the natural environment. As a device, the frequency generator 10 generates a frequency in the range of 0.5 Hz to 2 KHz and applies it to the mixer 20. In addition, the bipolar pulse generator 30 generates a bipolar pulse signal and applies it to the mixer 20.

The mixer 20 mixes the signals applied from the frequency generator 10 and the bipolar pulse generator 30 and applies them to the pulse width controller 40.

That is, the frequency signal that is arbitrarily adjusted in the frequency range of 0.5 Hz to 2 KHz by the frequency generator 10 is modulated in the mixer 20 and the bipolar pulse signal applied from the bipolar pulse generator 30 to a pulse width controller. Is approved.

Accordingly, the bipolar pulse has a period of frequency generated by being adjusted in the frequency generator 10, and the pulse width is adjusted by the pulse width controller 40.

The signal applied from the pulse width controller 40 is applied to the pulse amplifier 50 to be amplified in the range of 2000V to 3000V, and the amplification range of the pulse is adjusted by the power supply 60.

In one embodiment, the power supply 60 is supplied with a commercial AC power supply of 220V, and in one embodiment, boosts up to 300V, and then selects a voltage within a range of 0V to 300V by a user's adjustment, together with a current. Applied to the pulse amplifier 50.

The pulse amplifier 50 amplifies the bidirectional pulse signal supplied from the pulse width controller 40 in the range of 2000V to 3000V in proportion to the voltage applied from the power supply 60.

The pulse amplifier 50 applies the amplified high voltage pulse signal to the positive electrode 90 and the negative electrode 92 of the atmospheric pressure or atmospheric discharge tube 80.

At this time, the discharge tube 80, as an embodiment, there is an input tube 87 and the output tube 88 of 1/4 inch diameter (Inch) size, respectively, the input tube 87 and the output tube 88, respectively A first valve 82 and a second valve 89 are provided to control the entry and exit of gas (Gas), and the first valve (82) is a pressure vessel (86) containing waste freon gas or toxic gas at high pressure. ) Is provided with a flow meter (84) for measuring the amount of gas flowing into the discharge tube (80).

Waste freon gas or other toxic gas supplied to the discharge tube 80 at atmospheric pressure or atmospheric pressure from the pressure vessel 86 through the first valve 82 is discharged from the pulse amplifier 50 to the anode 90 and the cathode 92. It is decomposed by the discharge of the high voltage applied to).

In one embodiment, when decomposing the Freon (CFC) gas, when a pulse high voltage of about 2000V is applied from the pulse amplifier 50 to the discharge tube 80, a red light is formed between the anode 90 and the cathode 92. While the plasma is generated, the freon gas is decomposed, and carbon (C) is decomposed and collected in black in the constituents of the freon (CF ₂ CL ₂ ) gas in the cathode 92 of the discharge tube 80. .

The black carbon (C) trapped in the cathode 92 means that the chemical molecular connection structure of the freon gas is decomposed, and therefore, that the freon gas which deteriorates the global environment is decomposed.

In this case, the user may control the decomposition rate of the gas decomposed in the discharge tube 80 by adjusting the frequency generator 10 and the pulse width controller 40.

In addition, since the plasma generation start voltage or the discharge start voltage between the anode 90 and the cathode 92 is different depending on the type of gas introduced into the discharge tube 80 and decomposed, the anode 90 ) Or by allowing the cathode 92 to move, the distance can be adjusted.

In another embodiment, when sulfur dioxide (SO ₂ ) gas, which is a noxious gas, is introduced into the discharge tube 80 and a high voltage pulse of about 2500V is applied, sulfur (S) is trapped on the cathode 92, thereby preventing the harmful gas. The result is that the covalent bond of sulfur dioxide (SO ₂ ), a gas, is broken and decomposed. In the above example, applying a higher voltage pulse signal of 2500 V is because the ionization potential of sulfur dioxide (SO ₂ ) is 1000 KJ / mol, which requires a high voltage.

The discharge tube 80 as described above generates plasma at atmospheric pressure or atmospheric pressure, and plasma is generated even when the discharge tube 80 is not used, but more effectively affects harmful gases or the global environment. This is because the gas can be decomposed and can be decomposed more efficiently by not mixing with other kinds of gases.

By adjusting the device of the above configuration well, that is, by adjusting the frequency generator 10, the pulse width controller 40, and the power supply 60, the appropriate pulse at the appropriate frequency from the pulse regulator 50 It has a width (Duration), the pulse signal of the required high voltage is applied to the discharge tube 80, and at the same time to adjust between the anode 90 and the cathode 92 so that the plasma is generated well.

By adjusting the first valve 82 and the second valve 89 of the gas in the pressure vessel 86 connected to the input tube 87 of the discharge tube adjusted as described above, the gas can be decomposed continuously while flowing.

Therefore, the present invention having the above-described configuration can easily and largely decompose harmful gases such as freon gas or sulfur dioxide, nitrogen dioxide and nitrogen compounds, which are bad for the global environment.

As described above, the present invention has an industrial utilization effect that can be easily and largely processed at a low cost in decomposing harmful gas or gas that destroys the global environment into a gas that is harmless to the human body or does not harm the global environment. have.
