Prior art for deodorization residual ozone removal as a background art related to the present invention is as follows. In the ozone removal filter (10-2003-0066594) activated carbon, T i O 2, and using a porous sheet filter in the zeolite mixture to the air cleaner, the ozone removal device (20-0247 258) is discharging the electric heater coil and the filter Installed in the duct to remove ozone.

상기의 배경기술에서, 고압방전 플라즈마 발생방법에서, 방전 전극의 간극을 일정하게 유지시키는 전기적 절연체의 표면에, 장기간 운전하여 이물질이 누적 코팅되어 절연파괴 현상이 발생하기 때문에 이를 계속 모니터하고 주기적으로 청소해주고 교체해야하는 과제가 있다. 그리고 발생된 플라즈마 입자의 수명이 지극히 짧아서 플라즈마 발생부에 오염기체를 직접 통과시켜야 하므로, 이때에 방전 전극의 오염으로 인해 전기적 임피던스가 변하여 플라즈마 발생 조건이 달라지는 문제점이 있다. 이를 피하기 위하여 플라즈마와 오염기체를 간접방식으로 접촉반응시킬 경우에는, 플라즈마 공급라인에 따른 플라즈마 밀도의 시간적 감쇄율을 보상하기 위하여, 플라즈마 발생 용량을 증가시켜야 하는 문제점이 있다. 그리고 상기 배경기술의 오염기체와 플라즈마의 접촉방식에서는 플라즈마 발생시점과 접촉시점에 시간적 차이가 있어서, 탈취효율이 감소되는 문제점이 있어, 이 시간 차를 최소로 해야 하는 과제가 있다.      In the above background, in the high-pressure discharge plasma generating method, the surface of the electrical insulator which maintains the gap of the discharge electrode is constant, and foreign matter is accumulated and coated on the surface of the electrical insulator for a long period of time, so that the breakdown phenomenon occurs. There is a challenge to do and replace. In addition, since the lifetime of the generated plasma particles is extremely short, the contaminant gas must be passed directly to the plasma generating unit. At this time, the electrical impedance is changed due to contamination of the discharge electrode, and thus the plasma generating condition is changed. In order to avoid this, when the plasma and the contaminated gas are indirectly contacted, there is a problem in that the plasma generation capacity must be increased to compensate for the temporal attenuation rate of the plasma density along the plasma supply line. In addition, there is a problem that the deodorization efficiency is reduced because there is a time difference between the time of plasma generation and the time of contact in the contact method of the contaminant gas and the plasma of the background art, and there is a problem of minimizing this time difference.

그리고, 상기의 배경기술에서, 활성탄 등 흡착구조를 갖는 촉매필터를 이용한 탈취장치는, 시간이 경과함에 따라 필터의 기공이 막혀 성능이 저하되고, 촉매담체 필터의 잦은 교체로 인한 비용증가의 단점이 있으며, 자외선램프를 사용한 광촉매코팅 활성탄필터의 경우에는 광촉매 표면의 오염으로 인한 광산화 성능 저하와, 램프의 필라멘트 수명에 따른 교체비용과 램프 표면 클리닝 장치가 추가로 설비 되어야 하는 단점이 있으며, 오존 탈취의 경우에는 인체에 유해한 잔류오존의 배출을 방지해야하는 과제가 있다. In the background art, a deodorizing device using a catalyst filter having an adsorption structure such as activated carbon has a disadvantage in that the pores of the filter are clogged over time, thereby degrading the performance and increasing the cost due to frequent replacement of the catalyst carrier filter. In addition, in the case of the photocatalyst coated activated carbon filter using an ultraviolet lamp, there is a disadvantage in that the photooxidation performance is deteriorated due to the contamination of the photocatalyst surface, the replacement cost according to the filament life of the lamp, and the lamp surface cleaning device must be additionally installed. In this case, there is a problem to prevent the discharge of residual ozone harmful to the human body.

본 발명의 목적은, 상기한 바와 같은 종래의 문제점을 해결하기 위하여, 소요전력이 낮은 저전압 교류로 동작되어 절연파괴의 문제점을 해결하고, 광촉매 코팅 도체 사이에서 입체형 마이크로플라즈마를 발생하여, 입체구조의 플라즈마 공간을 유입되는 오염기체가 전량 통과하면서 반복 접촉되어, 탈취 및 오존의 제거가 효과적으로 이루어지도록 하는 것이다. An object of the present invention, in order to solve the conventional problems as described above, is to operate at low voltage AC with low power consumption to solve the problem of dielectric breakdown, and the three-dimensional type between the photocatalyst coating conductor By generating microplasma, contaminant gas flowing into the three-dimensional plasma space is repeatedly contacted while passing through the entire volume, so that deodorization and ozone removal can be effectively performed.

상기와 같은 목적을 달성하기 위하여, 본 발명의 입체형 마이크로플라즈마 탈취 및 오존제거 장치에서는, 광촉매 용액을 코팅한 구형이나 팰릿형의 도체 간극에, 낮은 교류전압을 공급하여 좁은 공간에서 플라즈마가 밤하늘의 은하수처럼 무수하게 입체적으로 발생되는 수단을 제공하여, 고압방전에 따른 절연파괴의 문제점을 해결하는 수단을 제공한다. In order to achieve the above object, the three-dimensional shape of the present invention In the microplasma deodorization and ozone removal device, a low alternating voltage is supplied to a spherical or pallet-shaped conductor gap coated with a photocatalyst solution to provide a means for generating plasma innumerably three-dimensionally like the Milky Way in a narrow space, It provides a means to solve the problem of breakdown caused by discharge.

그리고 본 발명에서는 유입되는 오염기체가 전량 미세하게 나누어져 마이크로 플라즈마 공간을 입체적으로 통과하면서, 플라즈마 발생과 접촉의 시차가 없이 동시에 반응이 이루어지는 탈취 수단을 제공한다. 이때에 발생된 자외선이 광촉매와 광산화 작용을 하여 OH 라디칼을 생성하고, 프라즈마 내에서 생성된 오존, 전자, 이온 등이 오염기체, 잔류오존과 반응하여 탈취되는 특징이 있다. 그리고 처리량과 오염농도에 따라 탈취기의 면적과 중첩 회수를 설정하여, 소형에서부터 대형의 플라즈마 탈취장치를 구성할 수 있는 수단이 있으며, 상세한 내용은 발명의 실시를 위한 구체적인 내용에서 기술하고자 한다.In addition, the present invention provides a deodorizing means in which the incoming polluted gas is finely divided and passes three-dimensionally through the microplasma space, and the reaction is simultaneously performed without the time difference between plasma generation and contact. Ultraviolet rays generated at this time are photocatalytically generated to generate OH radicals, and ozone, electrons, and ions generated in the plasma react with contaminated gas and residual ozone. And there is a means to configure the area of the deodorizer and the number of overlaps according to the throughput and the pollution concentration, there is a means to configure a small to large plasma deodorizer, the details will be described in detail for the practice of the invention.

본 발명에 따르면, 절연파괴를 방지한 저전압으로 동작되는 초소형 입체 방전구조를 통하여, 입체적으로 마이크로 플라즈마를 발생시키는 효과가 있으며, 플라즈마 발생시점과 오염유체 접촉시점을 일치시켜 초기에 발생된 플라즈마를 최대한 탈취반응에 활용할 수 있는 효과가 있다. 그리고 본 발명에서는, 낮은 교류전력으로 발생되는 마이크로 플라즈마에, 오염기체와 잔류오존을 수많은 작은 공간으로 전량 분산 접촉시켜, 오염기체를 탈취할 수 있을 뿐만 아니라 인체에 유해한 잔류오존을 제거시키는 효과가 있어, 산업용 탈취시설에 조합하거나 독립적으로 적용할 수 있으며, 특히 코로나 집진, 음이온 발생, 공기청정기와 오존탈취시설 등에 본 발명의 기술을 활용하여 안전도를 높이는 효과가 있다.According to the present invention, through the microscopic three-dimensional discharge structure that operates at a low voltage to prevent dielectric breakdown, there is an effect of generating a micro-plasma in three dimensions, matching the time of plasma generation and the contact point of the contaminated fluid to maximize the plasma generated initially There is an effect that can be utilized in the deodorizing reaction. In the present invention, the microplasma generated by the low alternating current power is dispersed and brought into contact with the pollutant gas and the residual ozone in many small spaces, thereby deodorizing the pollutant gas and removing the residual ozone harmful to the human body. In addition, it can be combined with or independently applied to industrial deodorization facilities, in particular, by using the technology of the present invention, such as corona dust collection, anion generation, air purifier and ozone deodorization facilities has the effect of increasing the safety.

본 발명에 따른 광촉매로 코팅된 도체 그래뉼 간극에 낮은 교류전압을 인가하여 입체형 마이크로 플라즈마가 무수히 발생하는 구조를 나타낸 실시 예로서, 플라즈마 발생, 탈취 및 오존제거 장치의 동작을 첨부된 도면을 참조하여 더욱 상세하게 설명한다.      As an embodiment showing a structure in which the three-dimensional microplasma is generated by applying a low alternating voltage to the conductor granule gap coated with the photocatalyst according to the present invention, the operation of the plasma generation, deodorization and ozone removal apparatus with reference to the accompanying drawings It demonstrates in detail.

먼저, 도 1의 본 발명의 실시 예에서 나타낸 바와 같이, TiO2광촉매를 에타놀로 혼합하여 직경 2~4 mm 구형의 도체 그래뉼(10)의 표층에 두께가 오십 마이크로미터 전후로 코팅(11)한다. 이렇게 광촉매가 코팅된 도체구들을 알루미나 가교로 가로 세로 594 cm, 폭 4 cm의 입체형으로 고정시킨다. 양쪽의 다공판 전극에 삼십 볼트의 교류전압을 인가하면, 그래뉼과 이웃 그래뉼 사이에 마이크로 플라즈마(12)가 밤하늘의 은하수처럼 입체형 구조(13)로 발생된다. 이때에 자외선이 광촉매와 작용하여 OH라디칼을 발생하는 기작과, 이온, 전하, 오존, 전자들로 마이크로 플라즈마가 구성되어 있어, 유입되는 오염기체가 입체구조를 통과하면서 반복 분해되어 탈취 및 오존의 제거가 이루어지는 특징이 있다.First, as shown in the embodiment of the present invention of FIG. 1, the TiO 2 photocatalyst is mixed with ethanol to coat 11 around 50 micrometers in thickness on the surface of the conductive granule 10 having a diameter of 2 to 4 mm. The photocatalyst-coated conductor spheres were fixed in a three-dimensional shape of 594 cm in width and 4 cm in width by alumina crosslinking. When an alternating voltage of thirty volts is applied to both porous plate electrodes, a microplasma 12 is generated between the granules and the neighboring granules in a three-dimensional structure 13 like the Milky Way in the night sky. At this time, the ultraviolet light acts as a photocatalyst to generate OH radicals, and micro-plasma is composed of ions, charges, ozone, and electrons. There is a characteristic that is made.

이어서, 도 2에 나타낸 바와 같은, 입체형 마이크로 프라즈마 발생유니트의 실시 예로서, 입체형 나노플라즈마 발생 유니트(20), 오염유체 잔류오존 입력부(21), 광촉매 코팅된 도체 그래뉼(22), 절연 부도체(23), STS 타공 전극판(24), 교류전기 발생부(25), 교류전기 연결부(26)와 유출부(27)를 포함하여 구성된다.       Subsequently, as an example of the three-dimensional microplasma generating unit, as shown in FIG. 2, the three-dimensional nanoplasma generating unit 20, the contaminating fluid residual ozone input unit 21, the photocatalyst coated conductor granule 22, and the insulating insulator 23. ), An STS perforated electrode plate 24, an alternating current electric generator 25, an alternating current electrical connection 26, and an outlet 27.

본 발명에 따르면, 전량의 오염기체나 잔류오존이, 입체로 발생된 플라즈마 공간을 순차적(cascade)으로 전량 통과하므로, 탈취성능이나 잔류오존 제거가 효율적으로 이루어지는 특징이 있다. 이것은, 발생된 플라즈마에 도미넌트한 자외선이 광촉매와 광산화 작용을 하여 OH 라디칼이 생성되어, 오염기체나 잔류오존이 산화 분해되고, 그리고 발생된 마이크로 플라즈마에는 자외선 이외에 전자, 산소이온, 오존, 전하 등이 분포되어 있어 통과하는 오염기체의 탈취작용을 수반한다.       According to the present invention, since a total amount of contaminant gas and residual ozone passes through the three-dimensionally generated plasma space cascade, deodorization performance and removal of residual ozone are efficient. This is because ultraviolet light dominant in the generated plasma acts as a photocatalyst and a photocatalytic reaction to generate OH radicals, resulting in oxidative decomposition of contaminated gas and residual ozone, and in addition to ultraviolet light, electrons, oxygen ions, ozone, charges, It is distributed and is accompanied by deodorization of contaminated gas.
