The present invention relates to a plasma gas mixed water generator. Since the characteristics of the generated plasma gas are different depending on the type of plasma, a plasma generator suitable for the application is selected to produce plasma gas, for example, a plasma gas containing a lot of nitrogen oxide is selected.

Hereinafter, the plasma gas mixed water manufacturing device and plasma generating device of the present invention will be described with reference to the accompanying drawings.

The plasma gas mixture of nitrite ions dissolved in nitrogen dioxide in water can be used for processing meat products and can also be used as a nitrogen fertilizer for agricultural products. Ozone or plasma gas mixed water with dissolved OH radicals has excellent sterilizing and cleaning abilities and is used for cleaning agricultural products, sterilizing pests, and industrial cleaning such as semiconductors and displays.

Referring to FIG. 1, a chamber 2 is located within the inner space of a separate plasma gas generation and control device box 1 separate from the water use space, and a first plasma generator 3 is located inside the chamber 2. It is arranged, and a second plasma generator 4 can be added depending on the purpose. A blower (5) capable of supplying wind to the first plasma generator (3) is installed, and an air circulation path (6) is formed next to the chamber (2) to increase the concentration of the plasma gas, so that the blower (5) The air that has been plasma treated is circulated (a) so that it can be repeatedly circulated and plasma treated. A wind pressure generation guide (7) is configured in front of the blower (5) to be connected to a wind pressure sensor (8) capable of controlling the wind pressure generated by the blower (5) to control the wind volume, or a first plasma power supply ( 9) Alternatively, it is configured to control the second plasma power supply device 10.

The plasma gas (b) produced by the first plasma generator (3) and the second plasma generator (4) is supplied to the plasma gas flow controller inside the gas-liquid mixing device box (21) through the plasma gas transmission pipe (12). It passes through (25) and is supplied to the venturi tube (24), which is a gas-liquid mixing device, to produce a gas-liquid mixture (d) and stored in the water tank (41). Plasma is the fourth substance beyond gas, but for convenience, the term “gas-liquid mixture” is used. In reality, plasma and gas containing activated species are mixed.

A first pump 22 is configured to supply venturi input water (c) to the venturi tube 24, and the first pump 22 is connected to the water tank 41 so that water 42 is repeatedly circulated. By doing this, the concentration of the gas-liquid mixture (d) is increased, and after a certain period of time, when plasma water of a certain concentration is produced from the plasma water measurement sensor 34, the plasma water (f) is provided and utilized by the second pump (23). do. As the plasma water measurement sensor 34, an optical sensor, a PH sensor, an ORP sensor, a NOx sensor, and a dissolved ozone sensor can be used alone or in combination to measure the concentration of active species in the plasma mixed water.

The first water level sensor 27 and the second water level sensor 29 are located in the first water level pipe 26 and the second water level pipe 28 connected to the water tank 41, so that when the water level is below a certain level, the 1 The water level sensor (27) controls the solenoid valve (31) to fill the water tank (41) with external water supply (h). At this time, when external water is supplied (h), water passes through the water filter (30). When the water level is below the minimum water level, the second water level sensor 29 plays a safety role by blocking all devices.

The first plasma generator 3 and the second plasma generator 4 may be a gliding arc plasma generator, a DBD plasma generator, an ozone generator, or a UV light plasma generator.

In the above, the gas supplied to the plasma generator is preferably air, but if necessary, an inert gas such as nitrogen, oxygen, or argon can be supplied or added to the air.

In addition, the liquid supplied to the water tank 41 through the water supply path (h) is generally water, but if necessary, it may be a liquid containing chemicals or additives.

In addition, the wind pressure sensor not only controls the wind volume and wind pressure by the blower, but also is linked to the power control unit of the power supply device that supplies power to the plasma generator, as described above. If the wind pressure is above a certain value, the power of the power source is increased above a certain value, and conversely, if the wind pressure is below a certain value, the power of the power source is lowered below a certain value.

In the above, an embodiment is shown in which the second pump is configured to operate in order to discharge and use the plasma mixed water, but in some cases, an outlet through which the plasma mixed water is discharged from the water tank may be configured without the second pump.

FIG. 2 is a cross-sectional view of a gliding arc plasma generator that can be applied to the plasma generator of FIG. 1. That is, it is a diagram showing the configuration of an electrode that creates water vapor plasma by supplying water vapor to the gliding arc plasma, and the plasma generator can generate nitrogen compounds such as OH radicals and NH ₃ . Looking at the configuration, there is a second electrode 52 that is separated from the first electrode 51 by a certain distance, and a floating electrode 53 is disposed between the first electrode 51 and the second electrode 52, and the floating electrode The heat sink 54, which is part of (53), is contained in the water tank neck 56, and the water tank 55 is located at the bottom of the water tank neck 56. Although not shown in the drawing, it is a structure in which water is supplied so that the water height is constant. When gliding arc plasma is generated, the temperature of the electrode rises to several hundred degrees, and the water in the neck 56 of the bucket is evaporated by the heat generated from the heat sink 54 to generate water vapor, supplying water vapor to the plasma, thereby generating water vapor plasma. Arc water vapor plasma generation electrode increases OH radical production.

Although not shown in the drawing, it is another structure of a gliding arc plasma generator, in which a first electrode and a second electrode face each other, and a gliding arc water vapor plasma is generated by spraying water vapor between the first electrode and the second electrode using ultrasonic waves. Electrodes can be presented. The technology of atomizing water vapor with ultrasonic waves is widely known and can be implemented accordingly.

In the above, the liquid filled in the water tank is generally water, but if necessary, it may be a liquid containing chemicals or additives in the water.

In addition, the heating effect by the heat sink is strengthened by forming a water bottle neck with a narrow cross-sectional area in the water tank, but it is also possible to design a water tank with a cross-sectional area designed to be sufficient to obtain a heating effect and omit the water bottle neck.

In the above electrode structure, when the floating electrode is floating, one side of the power supply output may or may not be grounded. However, in order to ground the floating electrode, neither side of the power supply output must be grounded.

The voltage range applied to the first and second electrodes is 1 to 30 kV, the frequency range is DC to 100 kHz, and the power is 20 W to 2 kW.

Figure 3 shows a photograph of gliding arc plasma generation with a floating electrode, showing that plasma discharge is well achieved even though the center electrode is floating.

The gliding arc plasma has a plasma temperature of tens to hundreds of degrees and is suitable for producing nitrogen oxide gas with little ozone generation. On the other hand, in the case of high-temperature arc plasma, the amount of nitrogen oxides produced is not efficient compared to the energy input.

An application field for manufactured plasma nitrogen water is that it can serve as a nitrogen fertilizer that helps in the growth of agricultural products. Another application field for nitrite ion plasma water is to maintain freshness and improve color in meat products such as sausages, ham, and bacon. Can be used as a nitrite substitute. In general, in cured meat products, nitrite ions are primarily used as preservatives to inhibit the growth of various aerobic and anaerobic microorganisms, and in particular, can inactivate Clostridium botulinum bacteria, and are not inactivated even by long-term heat treatment. It can inhibit the growth of Bacillus cereus, Staphylococcus aureus, and Clostridium perfringens, which cause the production of toxic substances and corruption. In addition, as an antioxidant, it reduces the occurrence of rancid odor by suppressing fatty rancidity that occurs during the production of cured meat products, and myoglobin in the meat combines with nitrogen monoxide to produce nitrosylmyoglobin, which is involved in the development of cured meat color. It is involved in the development of unique and attractive flavors of cured meat products due to the generation of nitrogen-containing volatile components. Therefore, nitrite ions are an indispensable substance in the production of cured meat products, and are used all over the world. However, in the case of chemically synthesized nitrite (NaNO ₂ or KNO ₂ ), which is commonly used to supply nitrite ions, the increase in sodium in cured meat products due to the use of synthetic nitrite and the fact that it is a chemically synthesized additive are causing consumers to avoid salt products using nitrite. As the phenomenon of aversion to processed meat products is increasing, the development of natural nitrite ion additives that can replace synthetic nitrites is needed to satisfy consumer demands and continue the development of the meat processing industry, and the present invention is proposed as an alternative.

For the purpose of sterilization and cleaning, the gliding arc water vapor plasma generator, DBD type plasma generator, ozone generator, UV light plasma generator, etc. can be used. The ozone and OH radicals generated play a powerful sterilizing and cleaning role. Fields of application include fruit sterilization and cleaning, improved storage, eco-friendly pesticides as substitutes for chemical pesticides, semiconductor cleaning, display cleaning, automobile parts cleaning, odor removal, and water purification sterilization. It can be applied to various fields, such as:

The main gases generated during plasma discharge include NO, NO ₂ , N ₂ O, NH ₃ , O ₃ , and OH*, and the components that are easily soluble in water are NO ₂ , NH ₃ , and OH*, which are not susceptible to gas-liquid contact. There is no major problem, but NO, N ₂ O, and O ₃ do not dissolve well in water, and the solubility of NO is 0.056 g/L (20 ℃), the solubility of N ₂ O is 1.5 g/L (15 ℃), and O ₃ The solubility is 0.57 g/L (20 ℃). In order to improve the solubility of such insoluble gases, the configuration of a gas-liquid mixing mechanism is very important. In existing patents, bubblers and scrubbers are mainly used due to their simple structure, but they have the disadvantage of being inefficient due to low gas-liquid contact efficiency and the large size of the bubbles. The collision method has disadvantages such as a complex structure, large bubble size distribution, and limitations in reducing the bubble size. In the case of ozone water, which is widely used in actual commercial use, it is 0.001 to 0.005 g/L (room temperature) in the case of bubbler, scrubber, and collision methods, and is very insoluble in water, and the bubble size is as large as hundreds of ㎛ to mm. On the other hand, in the case of the venturi tube 24 method of the present invention, not only can the solubility be increased by more than 3 to 5 times at 0.01 to 0.02 g/L (room temperature), but the bubble size can also be manufactured very small, with an average of 50 ㎛ or less. . For reference, looking at the bubble size study by venturi nozzle (Journal of the Korea Academia-Industrial cooperation Society, Vol. 16, No. 9 pp. 6397-6402, 2015), in Table 1, the bubble size is 49.40 ~ 54.98 under certain conditions. ㎛ accounts for 50%, and the fraction smaller than 50 ㎛ accounts for 44.7%, showing that uniform and fine bubbles can be created.

Another high-performance method for dissolving gas in an aqueous solution is the pressurized membrane method, but it has the disadvantages of being complicated in structure, expensive, and difficult to maintain, such as replacing the membrane after a certain period of use. However, the venturi nozzle method proposed in this patent is maintained. It is a method that is convenient to manage, simple and efficient, and can very effectively dissolve microbubbles in an aqueous solution.
