본 발명은 공기 정화 시스템에 관한 것으로, 특히 청정공기를 요하는 병원, 제약회사, 연구실 등에 공급되는 공기를 제진 및 탈취는 물론 각종 미생물까지 완벽하게 제거할 수 있도록 구성된 바이오-그린 공기 정화 시스템에 관한 것이다.The present invention relates to an air purifying system, and more particularly, to a bio-green air purifying system configured to completely remove various microorganisms as well as to remove and deodorize air supplied to hospitals, pharmaceutical companies and laboratories requiring clean air. will be.
종전에는 에어필터를 통하여 공기를 정화시키거나, 물을 노즐로부터 미세하게 분사시켜 세균, 먼지등을 포집시키는 방법 및 장치가 제시되었다. 한국특허 공고번호 95-5982호에서는 미세하게 분무된 습윤입자 또는 실질적으로 0.5미크론 이하의 미세소적을 함유하는 공기를 이용함으로써 미스트 입자의 흡착효과에 의해 공기중의 미세한 입자와 미생물을 제거할 수 있음을 밝히고 있다.Previously, a method and apparatus for purifying air through an air filter or collecting microorganisms and dust by spraying water finely from a nozzle have been proposed. In Korean Patent Publication No. 95-5982, fine particles and microorganisms in the air can be removed by the adsorption effect of mist particles by using finely sprayed wet particles or air containing micro droplets of substantially 0.5 microns or less. Reveals.
또한, 공기 청정기와 싸이크론 및 크린룸으로 이루어진 공기 정화 시스템도 알려져 있다.Also known are air purification systems consisting of air purifiers and cyclones and clean rooms.
그러나 상기 방법이나 장치 및 시스템에서는 세균, 먼지, 가스등이 포집된 물을 계속 재순환시켜 사용해야 하기 때문에 시간이 경과함에 따라 세균이 증식되고, 가스에 대한 물의 용해도가 떨어지게 되며, 산소의 농도도 저하되므로 순환수를 자주 갈아야 하는 번거로움이 있고, 외부공기를 계속 도입하여야만 하나, 도시지역의 경우 대기중의 공기도 오염되어 있어 오히려 청정화 공정의 효율을 저하시키게 되는 등의 문제점이 있었다.However, in the above method, apparatus, and system, bacteria, dust, and gas must be recycled and reused. As time passes, bacteria grow, solubility of water in gas decreases, and oxygen concentration decreases. There is a need to frequently change the number of water, and outside air must be continuously introduced, but in the case of urban areas, air in the air is also contaminated, thereby reducing the efficiency of the purification process.
본 발명은 상기와 같은 종래의 문제점을 해결하고자 제안된 것으로서 생약제조 회사나 반도체 제조공장등 고도의 청정공기를 요구하는 장소의 크린룸에 공급하기 위하여 고려된 것이다.The present invention has been proposed to solve the above-mentioned problems, and is considered to supply a clean room of a place requiring high clean air, such as a herbal medicine manufacturing company or a semiconductor manufacturing factory.
본 발명은 공기 청정기내에서 사용하고난 물을 재순환시킬 때 스트레나 탱크 하면에 오존방출기를 설치하고 일정량의 오존을 주입케 함으로써 순환수를 살균, 탈취 및 정수토록 한 것이며 또한 인간의 호흡에 의한 산소량의 감소에 따라 산소발생 장치를 설치하여 충분량의 산소를 공급해 줌으로써 크린룸에 공급되는 공기가 고도의 청정도와 쾌적도를 유지하도록 함을 발명의 목적으로 한 것으로 그 특징은 다음과 같다.The present invention is to sterilize, deodorize and purify the circulating water by installing an ozone emitter at the bottom of the strainer tank and injecting a certain amount of ozone when recycling the water used in the air purifier. The purpose of the present invention is to provide a sufficient amount of oxygen by installing an oxygen generating device in accordance with the decrease, so that the air supplied to the clean room maintains a high degree of cleanliness and comfort.
1) 순환수에 오존을 주입하여 각종 세균의 살균과 용존가스를 산화시켜 세균의 증식을 방지하며 가스의 물에 대한 용해도를 높여진다.1) Inject ozone into circulating water to sterilize various bacteria and oxidize dissolved gas to prevent the growth of bacteria and increase the solubility of gas in water.
2) 크린룸의 공급 공기중에 산소발생장치에 의한 건조산소를 추가로 공급시켜 순환 공기중의 산소농도를 높혀주고 상대습도를 낮추게 하여 쾌적한 상태의 크린룸을 만들 수 있다. 이하 첨부된 도면에 의거하여 본 발명을 상세히 설명키로 한다.2) By supplying additional dry oxygen by oxygen generator to the supply air of clean room, it is possible to make clean room with pleasant condition by increasing oxygen concentration in circulation air and lowering relative humidity. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
크린룸(1)으로부터 재순환되는 공기와 외부공기 주입기(3)로부터 유입되는 공기는 리턴 챔버(2)내에서 혼합되어 공기 청정기(5)내로 도입된다.Air recycled from the clean room 1 and air flowing from the external air injector 3 are mixed in the return chamber 2 and introduced into the air cleaner 5.
공기 청정기(5)에서는 순환수가 순환수 분사펌프(16)에 의해 노즐로부터 미세하게 분사되어 세균, 먼지등을 포집하고 공기중에 포함된 가스상의 오염물을 용해시켜 줌으로 상기 혼합공기로 바뀌게 된다. 물이 미세하게 분사될때는 레너드 효과(Renerd effect)에 의해 음이온성 공기가 많이 발생되는데, 이러한 음이온성 공기는 고압방전에 의해 발생되는 음이온보다 수량적으로 훨씬 많고 자연상태에 가깝다.In the air purifier 5, the circulating water is finely sprayed from the nozzle by the circulating water injection pump 16 to collect bacteria, dust, and the like and to dissolve gaseous contaminants contained in the air to change the mixed air. When the water is finely sprayed, the anionic air is generated by the Leonard effect, which is much more quantitative than the anion generated by the high-pressure discharge and close to the natural state.
이때 사용된 순환수는 공기 청정기(5) 내부 하단의 집수부(6)에 모이게 되고, 이 순환수는 스트레나 탱크(7)로 이송되어 살균, 제진, 정화, 탈취 및 여과 과정을 거치게 되는바, 스트레나 탱크(7)내로 유입된 순환수는 부스타 펌프(17)의 펌핑압력에 의해 벤츄리타입의 내부 형상으로 갖는 인젝터(18)내로 유입되어 진다.At this time, the used circulating water is collected in the water collecting unit 6 at the lower end of the air cleaner 5, and the circulating water is transferred to the strainer tank 7 to undergo sterilization, dust removal, purification, deodorization and filtration. The circulating water introduced into the strainer tank 7 is introduced into the injector 18 having the internal shape of the venturi type by the pumping pressure of the booster pump 17.
부스타 펌프(17)를 통과한 순환수가 인젝트(18)내의 벤츄리관 내부를 통과하는 순간 순환수의 유속은 빨라지게 되며 이때 인젝트(18) 하부에 연결되어진 오존발생기(10)에서 생성된 오존(O3)이 벤츄리관 내부를 통과하는 순환수와 혼합되면서 오존방출기(9)를 통해 스트레나 탱크 내부로 젯트 분사되게 된다.As soon as the circulating water passing through the booster pump 17 passes through the inside of the venturi tube in the inject 18, the flow rate of the circulating water becomes faster. (O 3 ) is jetted into the strainer tank through the ozone emitter 9 while being mixed with the circulating water passing through the inside of the venturi tube.
이때 순환수 1톤당 오존은 0.5∼1g 주입되어 혼합하므로 오존 주입 농도는 0.5∼1ppm 범위이며 오존(O3)의 강력한 산화 작용에 의해 살균, 탈취, 정수를 행하고 필터(8)를 통과하면서 이물질을 여과하게 되며 증발로 인한 부족분의 물은 재보충 되어서 공기 청정기(5)내로 재순환 하게 된다.At this time, 0.5 to 1 g of ozone is injected and mixed per ton of circulating water, so the concentration of ozone is in the range of 0.5 to 1 ppm and sterilizes, deodorizes and purifies by strong oxidation of ozone (O3), and filters foreign substances while passing through the filter (8). The insufficient water due to evaporation is replenished and recycled into the air cleaner (5).
또한 물속에서 분해되지 않은 약 10%의 잉여 오존은 Tio2, Cuo, MnO2으로 조성된 오존 파괴촉매(11)를 통과하면서 분해되어 외부로 배출되어진다.In addition, about 10% of the excess ozone that is not decomposed in water passes through the ozone destruction catalyst 11 composed of Tio 2 , Cuo, and MnO 2 , and is decomposed and discharged to the outside.
공기청정기(5)를 통과한 순환 공기는 높은 수분함유량을 갖고 있으며 관을 통해 싸이크론식 공기-물 분리기(13)로 이동되어 원심분리에 의해 수분을 분리한 후 크린룸(1)으로 공급되는데 이때 공기청정기(5)와 공기-물 분리기(13) 사이에 PSA Type 산소 발생장치(12)를 설치하여 부족한 산소의 양 만큼을 보충하게 된다.The circulating air passing through the air purifier (5) has a high water content and is moved to a cyclone-type air-water separator (13) through a pipe to separate the water by centrifugation and then supplied to the clean room (1). The PSA type oxygen generator 12 is installed between the purifier 5 and the air-water separator 13 to compensate for the insufficient amount of oxygen.
공기-물 분리기(13)를 통과한 순환공기는 가열기(14)에서 온도조절에 의해 최적의 습도를 유지케 한 후 크린룸(1)으로 공급되어 진다.The circulating air passing through the air-water separator 13 is supplied to the clean room 1 after maintaining the optimum humidity by temperature control in the heater 14.
한편 순환 공기의 온도가 높아지면 레너드 효과에 의한 음이온 발생효율이 떨어지게 되므로 이때는 냉동기(15)에 의해 공기청정기 내의 공기 온도를 18∼20℃로 유지토록 한다.On the other hand, when the temperature of the circulating air is increased, the negative ion generation efficiency due to the Leonard effect is lowered. At this time, the air temperature in the air cleaner is maintained by the refrigerator 15 at 18 to 20 ° C.
이와 같이 본 발명은 종래 물을 재순환시켜 사용하던 공기 정화 시스템에서 발생하였던 문제점인 시간의 경과에 따른 세균증식, 가스에 대한 순환수의 용해도 저하, 산소 농도의 감소, 탈취의 어려움 등 종전의 결점을 해결하였을 뿐만 아니라, 물을 자주 교환하지 않고 순환수를 계속 사용하면서도 순수한 청정공기를 공급할 수 있어 항상 쾌적한 상태의 크린룸을 유지토록 한 것이다.As described above, the present invention overcomes the drawbacks of the conventional defects such as bacterial growth, deterioration in solubility of circulating water in gas, reduction of oxygen concentration, and difficulty in deodorization, which are problems caused by the air purification system used by recirculating water. In addition to solving the problem, it is possible to supply pure clean air while continuing to use the circulating water without frequent water exchange, so that the clean room is always maintained in a comfortable state.
