Description

플라즈마 살균수 제조장치Plasma sterilizing water production device
본 발명은 식품이나 의약 분야 등에 사용되는 플라즈마 살균수 제조장치에 관한 것으로, 더욱 구체적으로는 물이 흐르는 살균수 제조배관에서 플라즈마가 생성되고 및 생성된 플라즈마가 물에 포화되어 골고루 혼합되는 과정을 통해 플라즈마 살균이 이루어지도록 한 수단으로 안전한 살균수를 얻을 수 있는 플라즈마 살균수 제조장치에 관한 것이다.The present invention relates to an apparatus for producing plasma sterilized water used in the field of food or medicine, and more specifically, through a process in which plasma is generated in a sterilized water production pipe through which water flows, and the generated plasma is saturated with water and mixed evenly. The present invention relates to an apparatus for producing plasma sterilizing water capable of obtaining safe sterilizing water as a means to effect plasma sterilization.
일반적으로 저온플라즈마는 기체가 상전이된 물질에 가까운 형태의 집단으로 전자와 이온이 분리 되어 집합하고 있으며 에너지가 높아서 접촉하는 물질과 반응하면 대상물질의 이온화나 성질을 개질하는 매개가 되기도 한다. In general, low-temperature plasma is a group in the form of a gas-phase-transferred substance, and electrons and ions are separated and collected, and when it reacts with a substance in contact with high energy, it is also a medium to modify the ionization or properties of the target substance.
특히 전기분해와 마찬가지로 친환경 공정으로 화학공정에 참여 할 수 있으므로 미래의 화학산업에 기여하는 정도가 제일 큰 기술로 분류되고 있다. 전기분해는 전기에너지를 가하여 화학결과물을 만들어내는 것이 특징이고, 플라즈마는 전기에너지로 플라즈마를 생산 한 뒤에 플라즈마 에너지가 화학결과물을 만들기도 하지만 물리적 결과물을 만드는 것이 전기분해와 다른 점이라고 할 수 있다. 대기상에서와는 다르게 수중에서 플라즈마를 생산 하는 것이 매우 어려운 작업이 된다. 수중에 기포를 발생 시키고 그 기포내에 있는 가스를 재료로 하여 플라즈마를 생산하여야 하므로 기포의 생성방법과 함께 물과의 통전을 피하여 생성 되는 기포내에 플라즈마를 생성하여 수중에 반응시키는 방식의 플라즈마 반응기 설계는 고비용의 장치비를 감수해야 하기 때문에 일반적인 소독수 제조에는 적합하지 못하게 된다. In particular, it is classified as the largest technology that contributes to the future chemical industry because it can participate in chemical processes as an eco-friendly process like electrolysis. Electrolysis is characterized by applying electrical energy to produce a chemical product. Plasma energy produces a chemical product after plasma is produced using electric energy, but it can be said that the physical product is different from electrolysis. Unlike in the atmosphere, it is very difficult to produce plasma in water. Plasma reactor design in which plasma is generated in water and reacted in water by generating plasma in the generated bubble by avoiding current with water along with the bubble generation method, as it is necessary to produce plasma using the gas in the bubble as a material. It is not suitable for general disinfection water production because it has to bear high equipment cost.
그래서 플라즈마를 이용하는 수처리는 플라즈마 반응기를 수중이 아닌 외부에 설치하여 플라즈마를 생산한 후에 생산된 플라즈마를 수중에 투입하는 방식이 일반적이다. 플라즈마가 생산하는 에너지는 크게 파장과 입자성 선종 화학종들인데 플라즈마 화학종들 중에서 수중의 미생물들을 제거하는데 제일 많은 기여를 하는 것이 오존이다. Therefore, in the water treatment using plasma, a plasma reactor is generally installed outside the water to produce plasma, and then the produced plasma is injected into water. The energy produced by plasma is largely wavelength and particulate adenoma species. Among plasma species, ozone contributes the most to removing microorganisms in water.
그런데 대기상에서는 플라즈마 자외선 선종에 오존이 노출되어 바로 산소원자 하나가 활동상태로 해리가 되어 활성종이 되지만 수중에서는 플라즈마 선종이 굴절되어 오존에 미치지 못하므로 수중오존은 별도의 용해장치를 두어서 오존의 산소원자 하나를 해리하여 활동성 산소로 만들어야 하는 공정이 필요하였다. 종래 제일 많이 쓰이는 용해 장치가 기포를 발생시켜 기포간의 충돌에너지로 산소원자를 해리하는 것이었다. However, in the atmosphere, ozone is exposed to plasma ultraviolet rays and immediately one oxygen atom dissociates into an active state and becomes an active species. A process was needed to dissociate one atom to make active oxygen. The most widely used dissolving device in the related art was to dissociate oxygen atoms with collision energy between bubbles by generating bubbles.
그러나 화학적 에너지 당량의 차이로 해리되지 않고 잔류하는 오존이 많아서 효율은 전체효율에서 잔류하는 오존만큼 뺀 효율을 용해효율로 보고 있다. 즉 완성도 높은 효율에 미치지 못하는 단점이 있었다. 활동산소의 량은 수중에서 라디칼을 만들어 세균을 제거하는 제일 중요한 요소이기 때문에 오존과 같은 플라즈마 화학종의 수중해리 효율도 중요한 것이다. However, due to the difference in the chemical energy equivalent, there is a large amount of ozone remaining without dissociation, so the efficiency is considered as the dissolution efficiency by subtracting the total efficiency as much as the remaining ozone. In other words, there was a disadvantage that it did not reach high efficiency. Since the amount of active oxygen is the most important factor in removing bacteria by making radicals in water, the efficiency of dissociation of plasma species such as ozone in water is also important.
한편 종래의 전해 살균수 제조 방법은 수중에 염화나트륨과 같은 전해질을 넣어 전해조에서 아염소산이나 아염소산 나트륨을 만들어 수중에 투입하여 미생물을 사멸시키는 방법으로 전해 효율을 높이기 위하여 전해질의 농도를 높여서 인체에 해가 될 수 있거나 전해전류를 높여서 높은 전류로 인하여 용융된 전극의 불순물들이 수중에 잠복하고 있다가 식품이나 식기 등을 소독할 때 수중에서 식품이나 식기구 등으로 옮겨져서 인체가 흡수하면 해로운 단점이 있었다.Meanwhile, the conventional electrolytic sterilization water manufacturing method is a method of killing microorganisms by making chlorous acid or sodium chlorite in water by putting an electrolyte such as sodium chloride in water and putting it in water to increase the electrolytic efficiency. There was a detrimental disadvantage if impurities in the molten electrode are lurking in water due to high current by increasing the electrolytic current, and are transferred from water to food or tableware and absorbed by the human body when disinfecting food or tableware. .

이하 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다. 그리고 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우 그 상세한 설명을 생략한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.
본 발명에 의한 플라즈마 살균수 제조장치는, 살균수 제조배관(A)에 물이 통과하는 과정에서 플라즈마 살균이 이루어지도록 하되 상기 살균수 제조배관(A)은 플라즈마 생성부(10), 플라즈마 주입부(20), 플라즈마 반응부(30)로 각각 분할 구획되어 플랜지로 연결하는 구성으로 이루어져 있다.The plasma sterilizing water production apparatus according to the present invention allows plasma sterilization to be performed in the process of passing water through the sterilizing water production pipe (A), but the sterilizing water production pipe (A) is a plasma generating unit 10, a plasma injection unit It is divided into 20 and the plasma reaction unit 30, and is connected to each other by a flange.
상기 플라즈마 생성부(10), 플라즈마 주입부(20), 플라즈마 반응부(30)를 각각 구성하는 제1,2,3하우징(11)(21)(31)은 산이나 알칼리에 부식이나 전식이 없는 폴리에틸렌이나 우레탄 소재로 내화학성을 구비하도록 함이 바람직하며, 금속이나 PVC소재는 플라즈마가 생성하는 활성종에 의하여 부식 및 전식이 되어 인체에 해로운 불순물을 수중에 침출시킬 수 있기 때문이다.The first, second, and third housings 11, 21 and 31 constituting the plasma generating unit 10, the plasma injection unit 20, and the plasma reaction unit 30, respectively, are resistant to corrosion or electrolysis by acid or alkali. It is preferable to have chemical resistance with polyethylene or urethane material that is not present, and since metal or PVC materials are corroded and electrophoresed by active species generated by plasma, impurities harmful to the human body can be leached into the water.
상기 플라즈마 생성부(10)는, 양단에 제1플랜지(11)가 형성되고 연결관(13)이 구비되어 있는 제1하우징(11)과; 상기 제1하우징(11)의 내부에 설치되고 연결관(13)과 연통되어 물이 통과되는 원통형의 내부전극(14)과; 상기 내부전극(14)의 외주면에 삽입되는 세라믹 유전체(15)와; 상기 세라믹 유전체(15)의 외주면에 삽입되는 외부전극(16)과: 상기 외부전극(16)과 제1하우징(11)의 이격된 공간부에 형성되어 플라즈마를 수용하는 플라즈마 수용실(17)과; 상기 플라즈마 수용실(17)의 일측에 공기압 유입구(18)가 구비되고 타측에 플라즈마 배출구(19)가 구비되어 있다.The plasma generating unit 10 includes: a first housing 11 having first flanges 11 formed at both ends and a connection pipe 13 provided; A cylindrical internal electrode (14) installed inside the first housing (11) and communicated with the connection pipe (13) through which water passes; A ceramic dielectric (15) inserted into the outer circumferential surface of the internal electrode (14); An external electrode 16 inserted into the outer circumferential surface of the ceramic dielectric 15, and a plasma receiving chamber 17 formed in a space spaced apart from the external electrode 16 and the first housing 11 to receive plasma, ; An air pressure inlet 18 is provided on one side of the plasma receiving chamber 17 and a plasma outlet 19 is provided on the other side.
상기 플라즈마 생성부(10)의 제1하우징(11)은 양단에 제1플랜지(11)가 형성되어 일측은 물을 살균하기 위한 급수관(미도시)과 연결되고 타측은 플라즈마 주입부(20)의 제2플랜지(21)와 연결되며, 제1플랜지(11)의 내측에 위치한 연결관(13)은 내부전극(14)과 연통될 수 있도록 되어 있다.The first housing 11 of the plasma generating unit 10 has first flanges 11 formed at both ends, and one side is connected to a water supply pipe (not shown) for sterilizing water, and the other side of the plasma injection unit 20 The connection pipe 13 connected to the second flange 21 and located inside the first flange 11 is configured to communicate with the internal electrode 14.
상기 내부전극(14)과 외부전극(16)은 외부에서 고압전원을 인가하여 플라즈마를 생성할 수 있도록 하되 상기에서 내부전극(14)이 양전극이면 외부전극(16)은 음전극과 연결되고, 반대로 내부전극(14)이 음전극이면 외부전극(16)은 양전극과 연결이 되도록 하며, 이러한 내부전극(14)과 외부전극(16)은 타이타늄으로 된 지지체 표면에 전기전도성 다이아몬드가 코팅되어 전기저항성을 최소화하면서 용융점 및 내화학성을 갖도록 하여 인체 안정성을 높일 수 있도록 함이 바람직하다.The internal electrode 14 and the external electrode 16 can generate plasma by applying a high-voltage power from the outside. In the above, if the internal electrode 14 is a positive electrode, the external electrode 16 is connected to the negative electrode, and vice versa. If the electrode 14 is a negative electrode, the external electrode 16 is connected to the positive electrode, and the internal electrode 14 and the external electrode 16 are coated with an electrically conductive diamond on the surface of a titanium support to minimize electrical resistance. It is desirable to have a melting point and chemical resistance to increase human stability.
그리고, 상기 플라즈마 생성부(10)를 구성하는 내부전극(14)의 외주면에서부터 순차적으로 삽입되는 구성으로 이루어진 내부전극(14)과 세라믹 유전체(15) 및 외부전극(16)은 서로 밀착되게 결합되어 삽입된 상태를 유지하도록 함이 바람직하다.In addition, the internal electrode 14, the ceramic dielectric 15, and the external electrode 16 configured to be sequentially inserted from the outer circumferential surface of the internal electrode 14 constituting the plasma generating unit 10 are in close contact with each other. It is desirable to keep the inserted state.
상기 내부전극(14)과 외부전극(16)은 타이타늄 지지체 표면에 전기전도성 다이아몬드가 코팅된 구성으로 이루어지되 다이아몬드를 코팅하는 수단으로는 붕소도핑 다이아몬드가 쓰일 수도 있으나, 붕소도핑 다이아몬드 전극은 진공실에서 기상증착하여 생산하므로 두께가 마이크미터 수준으로 너무 얇아 플라즈마 생성시 중심부 온도에 의하여 다이아몬드를 지지하는 지지체가 열변형이 되어 다이아몬드의 박리가 일어나기 쉬우므로 두께가 적어도 1mm이상이 되도록 하기 위하여 다이아몬드 분말을 용사하여 지지체에 지지하는 것이 바람직하다. The inner electrode 14 and the outer electrode 16 are made of a configuration in which an electrically conductive diamond is coated on the surface of a titanium support, but a boron-doped diamond may be used as a means of coating the diamond, but the boron-doped diamond electrode is vaporized in a vacuum chamber. Since it is produced by evaporation, the thickness is too thin to the level of micrometres. When plasma is generated, the support that supports the diamond is thermally deformed and the diamond is easily peeled off. Therefore, in order to make the thickness of at least 1 mm or more, the diamond powder is sprayed. It is preferable to support it on a support.
즉, 내부전극(14)과 외부전극(16)의 지지체는 타이타늄이 제일 적당하고 1mm이상의 다이아몬드 두께에서는 지지체가 열변형이 되더라도 높은 경도의 다이아몬드 결합장력에 의하여 잘 박리 되지 않는다. 붕소를 도핑하는 것은 절연체인 다이아몬드를 전도체로 만들기 위함인데 기상증착시에는 진공분위기에서 탄소가스와 붕소가스와 수소가스를 혼합하여 지지체에 박막하므로 다이아몬드 성장시에 함께 붕소도 도핑 되지만 용사는 대기상에서 이루어지므로 일반적인 기술로는 붕소의 도핑이 어려워 질 수도 있다. 그러나 제2상의 물질인 붕소를 다이아몬드 지지체 표면에 증착하는 것은 고온로를 이용하거나 이온 스퍼터링(sputtering)을 하게 되면 다이아몬드에 표면에 붕소가 지지되어 전도성을 가지게 된다. 다이아몬드는 용융점이 높고 내화학성이 높아서 수중에 전극 용융물을 내어놓기 어려우므로 인체 안정성을 도모할 수 있게 된다.That is, titanium is the most suitable support for the internal electrode 14 and the external electrode 16, and at a diamond thickness of 1 mm or more, even if the support is thermally deformed, it is not easily peeled off due to a high hardness diamond bonding tension. Doping with boron is to make diamond, which is an insulator, a conductor.In vapor deposition, carbon gas, boron gas, and hydrogen gas are mixed in a vacuum atmosphere to make a thin film on the support, so boron is also doped during diamond growth, but thermal spraying is performed in the atmosphere. Therefore, doping of boron may be difficult with a general technique. However, when boron, which is a material of the second phase, is deposited on the surface of the diamond support using a high-temperature furnace or performing ion sputtering, boron is supported on the surface of the diamond, and thus it has conductivity. Since diamond has a high melting point and high chemical resistance, it is difficult to put out the molten electrode in water, so it is possible to achieve human stability.
상기 플라즈마 생성부(10)에 채용되는 세라믹 유전체(15)는 알루미나 소재로서 내부전극(14)과 외부전극(16) 사이에 수납되어 저온의 플라즈마를 생성하는 중요한 개체가 된다. 세라믹 유전체(15)가 없는 경우에는 내부전극(14)과 외부전극(16)에 전원을 인가하면 전극의 일부분에만 전압이 집중되어 방전이 일어나 긴 전극 전체에 걸쳐서 평등한 플라즈마를 생성하기 어렵게 된다. The ceramic dielectric material 15 employed in the plasma generating unit 10 is an alumina material and is accommodated between the internal electrode 14 and the external electrode 16 to become an important object generating low-temperature plasma. In the absence of the ceramic dielectric 15, when power is applied to the internal electrode 14 and the external electrode 16, voltage is concentrated only on a portion of the electrode, resulting in discharge, making it difficult to generate equal plasma over the entire long electrode.
이러한 세라믹 유전체(15)는 전도체는 아니지만 유전율이 높아 방전은 차단하고 각 전극에 전하를 전달하여 플라즈마를 생성하는 장벽 역할과 다리 역할을 동시에 수행한다. 유전체 소재를 유전율이 높은 석영을 쓸 수도 있으나 석영은 충격에 약해 조그만 외부 충격에도 파손되기 쉽다. Although not a conductor, the ceramic dielectric 15 is not a conductor, but has a high dielectric constant, which blocks discharge and transfers electric charges to each electrode to generate plasma as a barrier and a bridge at the same time. Quartz with a high dielectric constant may be used as the dielectric material, but quartz is vulnerable to impact and is easily damaged by a small external impact.
상기 플라즈마 수용실(17)은 제1하우징(11)과 외부전극(16)의 이격된 공간부에 형성되되 상기 플라즈마 수용실(17)의 일측에 구비된 공기압 유입구(18)는 에어블로워(미도시)와 연결되어 공기압이 유입될 수 있도록 하고, 타측에 구비된 플라즈마 배출구(19)는 플라즈마 주입부(20)의 플라즈마 유입구(24)와 호스로 연결되어 플라즈마 수용실(17)에서 생성된 플라즈마를 플라즈마 주입부(20)로 이동될 수 있도록 한다.The plasma receiving chamber 17 is formed in a space spaced apart from the first housing 11 and the external electrode 16, and the air pressure inlet 18 provided at one side of the plasma receiving chamber 17 is an air blower (not shown). Si) to allow air pressure to be introduced, and the plasma outlet 19 provided on the other side is connected to the plasma inlet 24 of the plasma injection unit 20 by a hose to generate plasma in the plasma receiving chamber 17 To be moved to the plasma injection unit 20.
즉, 플라즈마 수용실(17)의 일측 공기압 유입구(18)를 통해 플라즈마 생성부(10)에 에어블로워의 작동에 의한 공기압을 불어주게 되면, 플라즈마 생성부(10)의 내부전극(14)과 외부전극(16)에 전원을 인가하여 플라즈마 수용실(17)에서 생성된 플라즈마는 플라즈마 배출구(19)를 통해 플라즈마 주입부(20)로 이동시킨다.That is, when air pressure is blown to the plasma generating unit 10 through the air pressure inlet 18 at one side of the plasma receiving chamber 17, the internal electrode 14 of the plasma generating unit 10 and the external Plasma generated in the plasma receiving chamber 17 by applying power to the electrode 16 is moved to the plasma injection unit 20 through the plasma discharge port 19.
상기 플라즈마 주입부(20)는, 양단에 제2플랜지(21)가 형성되고 관체로 구비되어 있는 제2하우징(21)과; 상기 제2하우징(21)의 외측에 체크밸브(25)가 구비되어 있는 플라즈마 유입구(24)와: 상기 플라즈마 유입구(24)와 연통되고 제2하우징(21)의 내부 관로 일측에 밀페된 박스형으로 형성되고 벤츄리 효과를 갖도록 한 유도구조물(23)과; 상기 유도구조물(23)의 일측에 구비되어 제2하우징(21)의 내부 관로에 플라즈마를 주입할 수 있도록 하는 플라즈마 주입구(26)로 이루어져 있다.The plasma injection unit 20 includes a second housing 21 having second flanges 21 formed at both ends and provided as a tube body; A plasma inlet 24 provided with a check valve 25 on the outside of the second housing 21, and in a box-shaped form that is in communication with the plasma inlet 24 and sealed to one side of the inner conduit of the second housing 21. An induction structure 23 formed to have a Venturi effect; It consists of a plasma injection port 26 provided on one side of the induction structure 23 to inject plasma into the inner conduit of the second housing 21.
상기 플라즈마 주입부(20)의 제2하우징(21)은 양단에 제2플랜지(21)가 형성되어 일측은 플라즈마 생성부(10)의 제1플랜지(11)와 연결되고 타측은 플라즈마 반응부(30)의 제3플랜지(31)와 연결되며, 제2하우징(21)의 내부 관로는 내부전극(14)의 관로와 직경이 동일하게 형성되어 물의 흐름이 이루어지도록 되어 있다.The second housing 21 of the plasma injection unit 20 has second flanges 21 formed at both ends, one side is connected to the first flange 11 of the plasma generation unit 10, and the other side is a plasma reaction unit ( It is connected to the third flange 31 of 30), and the inner conduit of the second housing 21 is formed to have the same diameter as the conduit of the inner electrode 14 to allow water to flow.
상기 플라즈마 유입구(24)는 플라즈마 생성부(10)의 플라즈마 배출구(19)와 호스로 연결되어 플라즈마를 유입할 수 있도록 하되 플라즈마 유입구(24)에 구비된 체크밸브(25)는 제2하우징(21)의 관로를 통과하는 물이 호스를 통해 플라즈마 수용실(17)로 역류되는것을 방지토록 한다.The plasma inlet 24 is connected to the plasma outlet 19 of the plasma generating unit 10 by a hose to allow plasma to flow therein, but the check valve 25 provided in the plasma inlet 24 is a second housing 21 ) To prevent the water passing through the pipe from flowing back to the plasma receiving chamber (17) through the hose.
상기 제2하우징(21)의 내부 관로 일측에 형성되는 유도구조물(23)은 제2하우징(21)의 유입부분에서 중간지점에 이르는 부분에 설치되어 플라즈마 생성부(10)의 내부전극(14)에서 유입되는 물의 유속이 빨라지는 벤츄리 효과를 얻도록 함과 아울러 물의 흐름을 방해하는 와류작용을 하도록 한 다음 제2하우징(21)의 내부 관로 중간지점에서 물의 흐름 배출방향에 위치하는 부분에는 유도구조물(23)이 없는 구성으로 제2하우징(21)의 내부 관로가 좁혀졌다가 확장된 형태를 갖도록 하며, 이러한 유도구조물(23)이 없고 물의 흐름 배출방향에 위치하는 제2하우징(21)의 내부 관로에 플라즈마 주입구(26)가 구비되어 플라즈마를 주입하도록 한 구성으로 제2하우징(21)의 내부 관로를 통과하는 물에 플라즈마가 접촉되어 골고루 혼합이 이루어지도록 되어 있다.The induction structure 23 formed on one side of the inner conduit of the second housing 21 is installed at a portion extending from the inflow portion of the second housing 21 to an intermediate point, and the internal electrode 14 of the plasma generating unit 10 In addition to obtaining a venturi effect that speeds up the flow rate of water flowing in from, a vortex function is performed to prevent the flow of water, and then an induction structure is located at the middle point of the inner pipe of the second housing (21) in the direction of the discharge of water flow. With the configuration without (23), the inner pipe of the second housing 21 is narrowed and then expanded, and there is no such guide structure 23 and the inside of the second housing 21 is located in the direction of water flow discharge. The plasma injection port 26 is provided in the pipeline to inject plasma, and the plasma is brought into contact with the water passing through the inner channel of the second housing 21 to achieve evenly mixing.
즉, 플라즈마의 생성과 이동이 모두 밀폐된 상태에서 이동되어 접촉 대상인 물에 합류가 되는 것으로, 이는 이동경로상에서 대기에 노출되어 누설되는 부분이 없는 이상 밀폐된 이동경로상에서의 플라즈마 에너지 손실은 전체 플라즈마의 생산량에서 아주 적은 양이 손실이 되기 때문입니다.In other words, the generation and movement of plasma are both moved in a sealed state and merged with the water that is the target of contact.This means that plasma energy loss on the closed movement path is the whole plasma unless there is a part exposed to the atmosphere on the movement path and leaking. This is because a very small amount is lost in the output of.
