Description

오존발생용방전관구조{a discharge tube structure for ozone origination}Discharge tube structure for ozone origination

본 발명은 오존발생용방전관구조에 관한 것으로 특히,방전 전압이 적어 질소산화물 생성이 없을뿐더러 매우 순도높은 오존가스의 생산과 갱년에 따른 경시현상을 줄일수 있도록 하는 것이다.The present invention relates to the structure of the discharge tube for ozone generation, in particular, the discharge voltage is low, there is no generation of nitrogen oxides, and the production of very high-purity ozone gas and to reduce the aging according to the menopause.

오존은 3개의 산소원자가 4가지 형상의 공명구조로 결합된 형태로 존재하며, 물에 대한 용해도는 산소보다 수배에서 수십배 크지만 온도와 압력에 큰 영향을 받는다.Ozone exists in the form of three oxygen atoms combined in a four-shaped resonance structure. Solubility in water is several times to several tens of times larger than oxygen, but is greatly affected by temperature and pressure.

오존은 불소다음으로 강력한 산화력을 가지며,살균,탈취,탈색,유,무기물과의 반응성은 모두 강력한 산화력에 기인된 것이다.Ozone has the strongest oxidizing power after fluorine, and sterilization, deodorization, discoloration, reactivity with oil and inorganics are all due to strong oxidative power.

오존의 응용분야는 상수도처리와 오페수및 분뇨처리장에 널리 사용되며, 기타 펄프나 제지의 표백이나 의약품 제조등에도 사용된다.Ozone applications are widely used in water treatment, effluent and manure treatment plants, as well as in bleaching of pulp and paper or in the manufacture of pharmaceuticals.

이와같은 용도로 사용되는 오존의 발생은 주로 산소에 물리,화학적인 자극으로 에너지를 가해 오존으로 변화시키는 것인데,무성방전법,전해법,고주파전계법,방사선조사법 등이 있으나 산업쪽에서는 무성방전법이 에너지효율면,성능의 안정성, 조작및 제어의 편리성으로 가장 널리 보급되어 있다.Ozone generation used for this purpose is to change energy into ozone by applying energy by physical and chemical stimulation to oxygen, and there are silent discharge method, electrolysis method, high frequency field method, and radiation irradiation method. This energy efficiency, the stability of the performance, the convenience of operation and control are most widely spread.

일반적인 무성방전법은 도 1과 같이 전극사이에 유리나 세라믹같은 유전체를 끼우고 공기나 산소를 불어넣고 전극에 6㎸ ∼15㎸을 가하면 다음반응에 의하여 오존이 발생된다.In the general silent discharge method, ozone is generated by inserting a dielectric such as glass or ceramic between the electrodes, blowing air or oxygen, and adding 6 kPa to 15 kPa to the electrode as shown in FIG.

O2+ e----→O +O + e- O 2 + e - --- → O + O + e -

O2+ e----→O3+ O 2 + e - --- → O 3 +

0+02+M ---→O3+M0 + 02+ M --- → O3+ M

O2+O2---→O3+0O 2 + O 2 --- → O 3 +0

상기와 같은 무성방전의 경우 오존생성효율은 오존농도에 따라 달라지나 공기를 원료로 할 경우 10g∼35g/㎥, 산소를 원료로 할 경우에는 50g∼150g/㎥의 오존농도를 얻을수 있고,소비전력은 수냉식 냉각수온도 25℃의 경우,산소가 원료인때 10∼13㎾h/㎏-O3이다.In the case of the silent discharge as described above, the ozone production efficiency depends on the ozone concentration, but when the air is used as a raw material, the ozone concentration of 10 g to 35 g / m 3 and the oxygen as the raw material can be obtained. In the case of water-cooled cooling water temperature of 25 ° C., 10 to 13 mAh / kg-O 3 when oxygen is a raw material.

위와같은 종래의 오존발생기는 교류전압 6,000볼트에서 10,000볼트라는 높은 고전압을 사용하므로,열적인 스트레스를 많이 받는 단점이 있다.Since the conventional ozone generator uses a high voltage of 10,000 volts at an alternating voltage of 6,000 volts, there is a disadvantage of receiving a lot of thermal stress.

또한 방전관 내부에 평행의 간극이 유지된 대칭의 전극을 사용하므로 아크를 일으키는 전극에 먼지나 기타의 오염물질이 잘 부착되는 구조로 공기의 청정에 매우 각별한 장치가 필요로 한다.In addition, since symmetrical electrodes with parallel gaps are maintained inside the discharge tube, dust or other contaminants adhere well to the electrode causing the arc, and therefore, a very special device for clean air is required.

이에 본 발명에서는 종래의 오존생성방전관과는 달리 방전관 내부에 평행의 간극이 유지된 대칭의 전극을 사용치 않아 이물질등에 노출되어도 내구성이 향상될수 있는 방전관을 제공하고자 한다.Therefore, the present invention is to provide a discharge tube that can be improved durability even when exposed to foreign substances, such as using a symmetric electrode that maintains a parallel gap inside the discharge tube, unlike the conventional ozone generating discharge tube.

또한,종래의 경우와는 달리 600-2,000㎜ 정도의 긴관이 아닌 200㎜ 길이의 작고 콤팩트한 방전관에 의해서도 오존을 효율적으로 생산하는 장치를 제공하고자 한다.In addition, unlike the conventional case, to provide an apparatus for efficiently producing ozone by a small and compact discharge tube of 200 mm length rather than a long tube of 600-2,000 mm.

또 종래에는 수개의 시스템중 단 한개가 고장나면 장비전체가 올스톱 되나 본 발명에 따르면, 전원공급장치와 방전관을 각각 독립적으로 기능이 되게 하여,메인스위치를 내리지 않고서도 부품을 교체할수 있게 하여 유지보수에 편리하며, 시스템에 안정을 기하도록 하는 장치를 제공하고자 한다.In the related art, when one of several systems fails, the whole equipment is all-stop, but according to the present invention, the power supply unit and the discharge tube function independently of each other so that parts can be replaced without lowering the main switch. It is intended to provide a device which is convenient to the system and which makes the system stable.

상기와 같은 점을 감안하여 이하 첨부된 도면에 의하여 본 발명의 일실시 구성 및 작용을 알아보면 다음과 같다.In consideration of the above-mentioned point, the following describes the configuration and operation of the present invention by the accompanying drawings.

도 2는 본 발명에 따른 PCB기판과 조립된 방전관의 사시도,도 3은 도 1에 따른 방전관의 내부구조를 나타낸 참고도로서,내직경 6㎜ 외직경 10㎜,길이 200㎜ 세라믹관(2)내부에 내부전극으로 5㎜ 간격으로 나선스프링형상의 내산화성 코일(3)이 밀착매입되며,상기 세라믹관(2) 외부는 공간없이 두께 0.5㎜ 외부전극(1)을 씌워 형성한 외부전원단자(5)와 상기 내산화성코일(3)의 말단인 내산화성코일단자(6)를 PCB박스(4)에 연결구성 한 것이다.2 is a perspective view of a discharge tube assembled with a PCB substrate according to the present invention, Figure 3 is a reference diagram showing the internal structure of the discharge tube according to Figure 1, the inner diameter 6mm outer diameter 10mm, length 200mm ceramic tube (2) A spiral spring-shaped oxidation resistant coil 3 is tightly embedded at an interval of 5 mm by an internal electrode, and an external power supply terminal formed by covering an external electrode 1 having a thickness of 0.5 mm without a space is formed on the outside of the ceramic tube 2. 5) and the oxidation resistant coil terminal 6 which is the end of the oxidation resistant coil 3 are connected to the PCB box 4.

상기와 같이 구성된 본 발명의 방전관의 일실시 작용으로 본 발명에 따른 오존발생공정도(도 4)와 같이 교류전원 220V의 입력과 과전압및 써지전압제거기,온도상승보호장치,A/D변환기,필터축전장치,고주파생성장치,정궤환피드백발진장치,주발진장치보호회로,승압·정류장치,대기인입용펌프를 통해 본 발명에 따른 내직경 6㎜ 외직경 10㎜,길이 200㎜ 세라믹관(2)내부에 내부전극으로 5㎜ 간격으로 나선스프링형상의 내산화성 코일(3)이 밀착매입된 세라믹관(2)내로 공기를 흡기해 인가된 고주파전압으로 외부전극(1)과 내부전극인 내산화성코일(3)사이에 산화가스가 형성되며, 이물질은 내부전극과 유전체인 세라믹관과의 밀착으로 인해 형성되는 매우 강력한 코로나에 의해서 뒷쪽으로 밀려나가게 된다.As one embodiment of the discharge tube of the present invention configured as described above, as shown in the ozone generation process chart (Fig. 4) according to the present invention, the input of the AC power supply 220V and overvoltage and surge voltage eliminator, temperature rise protection device, A / D converter, filter Power storage device, high frequency generating device, positive feedback feedback oscillation device, main oscillation device protection circuit, boosting / rectifying device, air inlet pump according to the present invention 6mm outer diameter 10mm, length 200mm ceramic tube (2 Inside the ceramic tube 2 in which the spiral spring-shaped oxidation resistant coil 3 is tightly embedded at intervals of 5 mm with the internal electrode, air is sucked in and the external electrode 1 and the internal electrode are subjected to oxidation resistance An oxidizing gas is formed between the coils 3, and the foreign matter is pushed backward by a very strong corona formed due to the close contact between the internal electrode and the dielectric ceramic tube.

매우 약한 먼지나 수분은 이 코로나에 의해 태워져 없어지며 큰 먼지는 불균형적으로 형성된 전자계의 에너지로 인하여 뒷쪽으로 밀려나서 출구로 빠져나게된된다.Very weak dust or moisture is burned away by this corona, and large dust is pushed backward by the energy of the disproportionately formed electromagnetic field and exits the outlet.

참고로 본 발명에 적용된 방전관은 순수한 파인 세라믹으로 제조되어 하며, 다음의 규격을 갖추어야 함이 바람직하다.즉,방전관의 주요 재질은 알루미나계로서 Al2O3함유량은 90% 는 넘어야 한다.또한, 방전관의 수분및 유분의 함유량은 0.01% 이하이어야 하며, 소성시는 섭씨 1,200℃ 그리고 1,800℃ 두번 소성해야 하며, 전극의 유입구와 공기유로의 전체 원형이 찌그러 들지 말아야 하며,표면의 조도는 매끄럽고 돌출되거나 함몰되는 지점이 없어야 한다.Note the discharge tube is applied to the present invention shall be made of pure fine ceramics, have the following specifications also are preferred. That is, the main material of the discharge vessel is Al 2 O 3 content as alumina is overcome at least 90%. In addition, Moisture and oil content of the discharge tube should be 0.01% or less, and when firing, it should be fired twice at 1,200 ℃ and 1,800 ℃. There should be no point of depression.

전기 절연능력은 파인세라믹 고유의 특성을 유지해야 하며, 교류1,000볼트 매거로 체크하였을때 10 메그옴 이상의 절연능력을 보유하여 한다.The electrical insulation must maintain the unique characteristics of fine ceramics and must have an insulation capability of 10 megohms or more when checked with an alternating 1000 volt magazine.

이와같이 본 발명에 따른 오존발생용방전관구조에 의해 외부전극(1)이 유전체에 외부에 밀착된체, 내부전극은 유전체 내부관벽에 밀착매입된 형태로 매우 미약한 전압으로도 충분히 프라즈마를 방전할수 있도록 된것이다.As described above, the external electrode 1 is closely adhered to the dielectric by the ozone generating discharge tube structure according to the present invention, and the internal electrode is tightly embedded in the dielectric inner tube wall so that the plasma can be sufficiently discharged even at a very weak voltage. That's it.

이와같이 본 발명에 따른 오존발생용방전관구조에 의하면,종래와 같이 교류전압 6,000볼트에서 10,000볼트라는 높은고전압이 아니므로 방전에 많은 열이 생성되지 않아 열적인 스트레스를 많이 받지 않아 내구성이 크게 향상 되는 것이다.As described above, according to the ozone generating discharge tube structure according to the present invention, since it is not a high voltage of 10,000 volts at an alternating voltage of 6,000 volts, it does not generate much heat in the discharge and thus does not receive much thermal stress, thereby greatly improving durability. .

또한, 외부전극이 유전체에 외부에 밀착된체,내부전극은 유전체 내부관벽에 밀착매입된 형태로 먼지나 이물질이 점착될 공간이 없으며, 방전전압이 적어 질소산화물생성이 없으며 갱년에 따른 갱시 현상이 없는 유용한 발명인 것이다.In addition, the external electrode is in close contact with the dielectric and the internal electrode is in close contact with the dielectric inner tube wall, and there is no space for dust or foreign matter to adhere to it. It is not a useful invention.

또한,종래의 경우와는 달리 600-2,000㎜ 정도의 긴관이 아닌 200㎜ 길이의작고 콤팩트한 방전관에 의해서도 효율적인 오존을 생산하므로 메우 경제적이다.In addition, unlike the conventional case, it is very economical because it produces efficient ozone even by a small and compact discharge tube of 200 mm length rather than a long tube of 600-2,000 mm.

그리고,종래에는 수개의 시스템중 단 한개가 고장나면 장비전체가 올스톱 되나 전원공급장치와 방전관을 각각 독립적으로 기능이 되게 하여,메인스위치를 내리지 않고서도 부품을 교체할수 있게하여 유지보수에 편리하며, 시스템에 안정을 기할수 있었다.In the past, if only one of several systems failed, the whole equipment would be all-stop, but the power supply and discharge tube would function independently, allowing parts to be replaced without lowering the main switch. I was able to stabilize the system.
