Abstract

PURPOSE: Provided is an air purification method, which employs electric precipitator or HEPA(high efficiency particulate air) filter for removing particulate air pollutants, activated carbon filter for removing gaseous air pollutants. Especially, polluted air is passed through pre-filter for removing coarse dust before it is introduced into main filter. CONSTITUTION: Polluted air is preliminary filtered by passing through prefilter(1), and then it is introduced into HEPA filter(2) for removing micro dust. Herein, instead of HEPA filter, electric precipitator can be adopted. After particulate air pollutants are removed, dust-free air is introduced into activated carbon filter(3) because gaseous air pollutants are not removed by HEPA filter.

Description

산소를 공급하는 기능을 갖춘 공기정화기{Air purifier with oxygen supplier}Air purifier with oxygen supply {air purifier with oxygen supplier}

실내공기의 오염은 외부에 의해서만 생기는 것은 아니고, 사람이 생활하다보면 공기는 오염이 되며, 특히 많은 사람이 모이는 실내의 공기는 외부공기 이상으로 오염되고 있다. 담배연기, 먼지, 냄새, 잡세균 기타 여러 오염물질을 우리도 모르는 사이에 체내로 흡입되어 질병의 원인이 되고, 숨이 가쁘고 불쾌감이 생긴다.Pollution of indoor air is not only caused by the outside, but when people live, the air is polluted, and in particular, the indoor air where many people gather is polluted by more than the outside air. Tobacco smoke, dust, odors, various germs and other contaminants are inhaled into the body without our knowledge, causing illness, shortness of breath and discomfort.

가정 또는 지하실 등과 같은 장소에서 발생하는 미세한 먼지, 곰팡이 포자, 바이러스 균 등을 제거하기 위해서 기존에는 음이온 발생, HEPA 필터, 전기 집진 방식, 활성탄을 이용한 공기정화기를 사용하여 제거하고 있다.In order to remove fine dust, mold spores, viruses, etc. generated in places such as homes or basements, conventionally, anion generators, HEPA filters, electric dust collection methods, and air purifiers using activated carbon are removed.

일반적으로 이온식 공기정화기는 음이온을 생산하여 양이온으로 가득 찬 실내공기에 음이온을 투입함으로써 전기적 밸런스를 되찾아 맑고 깨끗한 공기로 중화시키는 방식이다.In general, ionic air purifiers produce negative ions and inject negative ions into indoor air filled with positive ions to restore electrical balance and neutralize them with clean and clean air.

분진을 제거하는 방식으로는 필터에 의한 방식이 있는데, 큰 분진을 제거하기 위해서는 Pre 필터 또는 Medium 필터를 사용하고, 수㎛ 크기의 미세한 분진은 반도체 청정공간 또는 원자력 시설에서 미세한 분진까지도 제거하기 위해 사용되는 HEPA 필터를 사용하여 제거하고 있다. 또한 미세한 분진을 제거하는 방식으로 방전극과 집진극내에서 코로나 방전을 일으켜 먼지에 전하를 주고 (-)로 대전된 입자가 집진극으로 이동하여 포집되는 전기 집진 방식이 사용되고 있다. 분진을 효과적으로 제거하기 위해서는 Pre 필터를 공기유입구에 설치하여 큰 분진과 미세한 분진을 분리하여 제거하여야 한다.There is a filter method to remove dust. Pre filter or medium filter is used to remove large dust, and fine particles of several μm size are used to remove even fine dust in semiconductor clean space or nuclear power facility. Is removed using a HEPA filter. In addition, as a method of removing fine dust, an electric dust collecting method is used in which a corona discharge is generated in the discharge electrode and the collecting electrode to charge dust and the negatively charged particles move to the collecting electrode and are collected. In order to effectively remove dust, a pre filter must be installed at the air inlet to separate and remove large dust and fine dust.

일반적으로 유해가스를 제거하기 위한 목적으로 활성탄 필터를 사용하고 있는데 활성탄으로 가능한 유해가스로는 한계가 있고 그 성능도 일부 유기물에 대하여 흡착 성능이 있고 특정 가스인 산성, 중성, 염기성류의 가스에 대하여는 흡착이 거의 일어나지 않는다.Generally, activated carbon filter is used to remove harmful gas. There is a limit to the harmful gas possible with activated carbon, and its performance is also adsorbed on some organic matters, and it is adsorbed on certain gases such as acid, neutral and basic gases. This rarely happens.

유해 가스를 제거하기 위해서는 활성탄에 화학적 활성을 부여한 첨착활성탄을 이용하여 효과적으로 제거가 가능하다. 일반 가정에서 발생하는 유해가스의 종류로는 암모니아, 황화수소, 메틸메르캅탄 등 여러 종류의 가스가 있다. 이러한 종류의 유해가스를 제거하기 위해서는 활성탄에 특수 화학 물질을 첨착하여 사용하고 있다. 본 발명자가 출원한 KI 첨착활성탄을 이용한 황화수소 가스 제거용[국내특허 216985]은 황화수소 가스에 대해 효과적으로 제거할 수 있다.In order to remove the harmful gas, it is possible to effectively remove the impregnated activated carbon imparting chemical activity to the activated carbon. There are various kinds of gases such as ammonia, hydrogen sulfide, and methyl mercaptan. In order to remove this kind of harmful gas, special chemicals are attached to activated carbon. Hydrogen sulfide gas removal using the KI impregnated activated carbon filed by the present inventors [domestic patent 216985] can be effectively removed for the hydrogen sulfide gas.

유해가스를 효과적으로 제거하기 위해서는 첨착활성탄을 사용한 필터 설치하여 사용하여야 하는데 일반적인 방식으로는 V-bed 형, 평판형, 원형 등의 방식이 있는데 이러한 방식은 차압이 많이 걸리기 때문에 사용하기가 어렵다. 본 발명자가 출원한 망체에 첨착활성탄을 부착하는 방법[특허출원중 제11201호(2000.3.7)]은 차압이 적게 걸리기 때문에 공기 정화기에 사용이 용이하다. 또한 차압이 적으면서 효과적인 방법으로는 foam type에 첨착활성탄을 부착시켜 사용하는 방법도 있다.In order to effectively remove the harmful gas, it is necessary to install and use a filter using impregnated activated carbon. Generally, V-bed type, flat type, and round type are used. This method is difficult to use because it takes a lot of differential pressure. The method of attaching the impregnated activated carbon to the network filed by the present inventor (No. 1121 (2000.3.7) in the patent application) is easy to use in an air purifier because the differential pressure is low. In addition, there is a method of attaching the impregnated activated carbon to the foam type as an effective method with low differential pressure.

산소를 발생시키는 장치로는 일반적으로 제올라이트(5A, 13X) 흡착제를 이용한 PSA(Pressure Swing adsorption) 방식을 사용하여 산소를 발생시킨다. 즉, 산소발생은 제올라이트를 흡착탑에 충전한 후 컴프레셔를 이용하여 대기중의 공기를 압축시켜 흡착탑에 압력을 가하여 질소와 산소의 흡착능 차이에 의해 질소를 흡착시키고 흡착제층을 통과하면서 질소와 분리된 산소를 공급하며 흡착된 질소는 압력이 해제되면서 다시 대기로 탈착이 된다. 이러한 방법으로 산소 발생량은 90%이상의 산소를 발생시킬 수 있다.As a device for generating oxygen, oxygen is generally generated using a pressure swing adsorption (PSA) method using zeolite (5A, 13X) adsorbent. In other words, the oxygen generation is filled with zeolite in the adsorption tower, and then compresses the air in the atmosphere using a compressor to apply pressure to the adsorption tower to adsorb nitrogen by the difference in the adsorption capacity of nitrogen and oxygen, and passes through the adsorbent layer to separate oxygen from the nitrogen The adsorbed nitrogen is desorbed back to the atmosphere as the pressure is released. In this way, the oxygen generation amount can generate more than 90% oxygen.

본 발명에서는 일반적인 공기정화기에서 적용하는 분진을 제거할 수 있는 필터를 설치하고, 유해가스를 제거하기 위하여 활성탄을 사용하는 대신에 본 발명자가 출원중인 망체에 흡착성능이 기존에 사용하고 있는 활성탄에 비해 우수한 첨착활성탄을 부착시킨 필터 여재를 이용하여 차압은 적게 걸리면서 악취가스를 효과적으로 제거하게 하였고, 산소 공급 장치를 이용하여 산소를 공급하여 신선하고 깨끗한 공기를 공급할 수 있도록 발명된 공기정화기이다.In the present invention, by installing a filter that can remove the dust applied in the general air purifier, instead of using activated carbon to remove the harmful gas, the present inventors compared to the activated carbon used in the adsorption performance to the existing network The filter medium attached with the excellent impregnated activated carbon effectively removes odor gas while reducing the differential pressure, and is an air purifier invented to supply fresh and clean air by supplying oxygen using an oxygen supply device.

본 발명은 상기와 같은 시스템으로 이루어진 것이다. 본 발명의 목적은 지하실 또는 사람이 많이 모이는 장소에 보다 깨끗하고 신선한 공기를 공급하고자 미세한 분진을 제거하기 위한 Pre 필터, HEPA 필터 또는 전기집진기, 악취가스를 제거할 수 있는 첨착활성탄 필터 그리고 신선한 산소를 공급할 수 있는 산소 발생 장치를 갖춘 공기정화기로서 사람이 생활하는 장소에서 발생하는 미세한 분진 또는 악취를 제거함으로서 인체에 영향을 주는 물질과 가스를 제거하여 쾌적한 환경을 만들고, 질병을 예방하고자 한다.The present invention consists of such a system. An object of the present invention is to provide a pre-filter, HEPA filter or electrostatic precipitator to remove fine dust, impregnated activated carbon filter to remove odor gas and fresh oxygen to supply cleaner and fresh air to basement or crowded places. As an air purifier equipped with an oxygen generator that can supply, it removes fine dust or odor generated in a place where people live, and removes substances and gases that affect the human body to create a pleasant environment and prevent disease.

본 발명에서는 일반적인 공기정화기에서 적용하는 분진을 제거할 수 있는 필터를 설치하고, 유해가스를 제거하기 위하여 활성탄을 사용하는 대신에 본 발명자가 출원중인 망체에 흡착성능이 기존에 사용하고 있는 활성탄에 비해 우수한 첨착활성탄을 부착시킨 필터 여재를 이용하여 차압은 적게 걸리면서 악취가스를 효과적으로 제거하게 하였고, 산소 공급 장치를 이용하여 산소를 공급하여 신선하고 깨끗한 공기를 공급할 수 있도록 발명된 공기정화기에 관한 것이다.In the present invention, by installing a filter that can remove the dust applied in the general air purifier, instead of using activated carbon to remove the harmful gas, the present inventors compared to the activated carbon used in the adsorption performance to the existing network The present invention relates to an air purifier invented to supply fresh and clean air by supplying oxygen using an oxygen supply device by using a filter medium attached with excellent impregnated activated carbon to reduce the differential pressure.

이하, 본 발명에 따른 공기정화기의 구성 및 그 작용에 대한 실시 예를 첨부 도면에 의거하여 상세하게 설명하면 다음과 같다.Hereinafter, an embodiment of the configuration and its operation of the air purifier according to the present invention will be described in detail with reference to the accompanying drawings.

도 1과 2는 공기정화기의 조립도와 구성을 나타낸 모식도이다. 실내에 존재하는 오염된 공기로부터 큰 분진을 제거하기 위해 설치된 Pre 필터(1)층을 통과하면서 큰 분진이나 이물질이 걸러진 공기는 다시 HEPA 필터(2)를 통과하면서 수㎛ 크기의 미세한 분진이 제거된다. 여기서 분진이나 이물질을 제거하기 위하여 사용하는 HEPA 필터 대신에 전기 집진기를 사용하는 것도 가능하다. 악취가스는 Pre 필터나 HEPA 필터로는 제거가 되지 않으므로 분진이 제거된 공기는 첨착활성탄 필터(3)를 통과하면서 악취가스가 정화된 깨끗한 공기가 Fan(4)을 통하여 배출된다. 실내의 공기는 이러한 공기정화 시스템에 의해 순환되면서 깨끗하고 신선한 공기로 정화되어 공급된다. 첨착활성탄이 충전된 필터(3)는 차압 등을 고려할 때본 발명자가 특허 출원한 망체에 첨착활성탄을 부착시킨 필터 여재나, Foam type에 첨착활성탄을 부착시킨 필터 여재를 사용하면 효과적이다. 특히 지하실이나 흡연실과 같은 실내 공기가 오염이 되어있으면서 산소가 부족한 장소나 겨울철에 문을 닫은 상태로 난방기를 사용할 경우 산소가 부족하여 머리가 맑지 못하며 산소 부족으로 인해 인체에 영향을 주는 장소에서는 도 1에서와 같은 공기정화기의 구성에서 산소 공급 장치(5)를 결합시켜 첨착활성탄 필터(3) 전단에 배관을 연결하여 공기정화기를 통해 산소를 공급하게된다.1 and 2 is a schematic diagram showing the assembly and configuration of the air purifier. The large dust or foreign substances filtered through the pre filter (1) layer installed to remove the large dust from the contaminated air in the room passes through the HEPA filter (2) to remove fine dust of several micrometers in size. . It is also possible to use an electrostatic precipitator instead of the HEPA filter used to remove dust and foreign matter. Since the odor gas is not removed by the pre filter or the HEPA filter, the air from which the dust is removed passes through the impregnated activated carbon filter 3, and clean air from which the odor gas is purified is discharged through the fan 4. The indoor air is circulated by this air purification system and supplied as clean and fresh air. The filter 3 filled with the impregnated activated carbon is effective to use a filter medium having the impregnated activated carbon attached to a network applied by the present inventors or a filter medium having the impregnated activated carbon attached to a foam type in consideration of differential pressure. Especially in places where oxygen is insufficient while the indoor air is contaminated, such as basements or smoking rooms, or when the heater is used with the door closed in winter, oxygen is deficient and the head is not clear. In the configuration of the air purifier as in the combination of the oxygen supply device (5) is connected to the pipe in front of the impregnated activated carbon filter (3) to supply oxygen through the air purifier.

도 3은 산소 공급 장치(5)에 관한 모식도이다. 산소 공급 장치(5)는 제올라이트(5A, 13X)가 충전된 PSA 방식에 의한 것이다. 컴프레셔(6)를 사용하여 두 개의 흡착탑(7)에 압력을 가하면서 질소를 흡착시키고 발생된 산소는 배출라인(8)을 통해 첨착활성탄 필터(3) 전단으로 공급되고, 공급된 산소는 첨착활성탄 필터(3)를 통해 실내로 유입된다. 흡착된 질소는 압력이 해제되면서 배출라인(9)을 통해 실외로 배출된다.3 is a schematic diagram of the oxygen supply device 5. The oxygen supply device 5 is based on a PSA system filled with zeolites 5A and 13X. The compressor (6) is used to pressurize the two adsorption tower (7) while adsorbing nitrogen, and the generated oxygen is supplied to the impregnated activated carbon filter (3) through the discharge line (8), and the supplied oxygen is impregnated activated carbon. It is introduced into the room through the filter (3). The adsorbed nitrogen is discharged to the outside through the discharge line (9) while the pressure is released.

공기정화기의 유해가스 흡착성능을 확인하기 위하여 암모니아 가스에 대한 흡착성능 실험을 수행하였다. 흡착성능 실험은 흡착제를 칼럼에 충전한 다음 유량 1 L/min, 농도 200ppm으로 고정시킨 후 시간에 따라 흡착성능 실험을 수행하였다. 실험에 사용된 흡착제는 일반활성탄과 첨착활성탄을 사용하여 실험하였다. 그림 1에서 보는 바와 같이 일반활성탄과 첨착활성탄의 암모니아에 대한 흡착성능이 첨착활성탄이 15배 이상 우수하게 나타나는 것을 볼 수 있다. 또한 가정에서 많이 발생하는 김치 냄새에 대하여도 흡착성능 실험을 수행하기 위하여 황화수소 가스를대상으로 흡착성능 실험을 수행하였다. 그림 2에서 보는 바와 같이 일반활성탄에 비해 첨착활성탄의 흡착성능이 40배 이상 우수하게 나타나는 것을 볼 수 있다.Adsorption performance experiment for ammonia gas was conducted to confirm the adsorption performance of harmful gas of air purifier. Adsorption performance experiment was carried out by filling the column with an adsorbent and then fixed at a flow rate of 1 L / min, concentration of 200ppm and the adsorption performance experiment over time. Adsorbents used in the experiment were tested using ordinary activated carbon and impregnated activated carbon. As shown in Figure 1, it can be seen that the impregnated activated carbon exhibits more than 15 times the adsorption performance of the activated carbon and the impregnated activated carbon to ammonia. In addition, the adsorption performance experiment was performed on hydrogen sulfide gas to perform the adsorption performance experiment on the smell of kimchi that occurs at home. As shown in Figure 2, the adsorption performance of impregnated activated carbon is 40 times better than that of ordinary activated carbon.

산소를 적정량 공급하기 위하여 산소의 농도를 조절 가능하여야 한다. 일반적으로 산소는 인체에 없어서는 안되지만 너무 과량의 산소를 장시간 공급되었을 경우에는 산소중독이 일어날 수 있다. 산소를 적절하게 조절이 가능하게 하기 위하여 PSA 방법에 의해 산소 발생실험을 수행하였다. 흡착탑(7)에 제올라이트를 충전한 후 대기중의 공기를 컴프레셔(6)을 이용하여 흡착탑에 압력을 가하여 질소를 흡착되고, 산소를 발생시키면서 배출라인(8)에서 산소 분석기를 이용하여 측정하였다. 산소 분석기는 산소의 농도를 30%이상은 측정이 되지 않아 질소로 희석하여 측정하였다. 발생된 산소 농도는 90%이상이 발생되었다. 공기정화기에 사용되는 유량에 맞춰 발생된 산소의 양을 유량조절기를 이용하여 실내의 산소의 양을 20-50% 정도로 맞출 수 있다.In order to supply an appropriate amount of oxygen, the concentration of oxygen should be adjustable. In general, oxygen is indispensable to the human body, but oxygen poisoning can occur when too much oxygen is supplied for a long time. Oxygen generation experiments were carried out by the PSA method in order to enable proper control of oxygen. Zeolite was charged to the adsorption tower (7), and the air in the atmosphere was pressurized to the adsorption tower by using the compressor (6) to adsorb nitrogen, and measured using an oxygen analyzer in the discharge line (8) while generating oxygen. The oxygen analyzer did not measure the concentration of oxygen more than 30% was measured by diluting with nitrogen. The generated oxygen concentration was more than 90%. The amount of oxygen generated according to the flow rate used in the air purifier can be adjusted to about 20-50% by using the flow controller.

이러한 공기정화시스템은 특정 사용 용도에 따라 선택적으로 사용이 가능하고 필터의 교체 및 보수가 용이하므로 사용하기가 편리하다.This air purification system is easy to use because it can be selectively used according to a specific use and the filter can be easily replaced and repaired.

본 발명에서 공기정화기는 본 발명자가 특허 출원한 첨착활성탄 필터 여재를 사용하여 성능을 극대화하면서 산소 공급 장치를 장착하여 깨끗하고 신선한 공기를 공급할 뿐만 아니라 산소를 공급하여 산소부족으로 인한 인체에 미치는 영향을 최소화하는데 있다.In the present invention, the air purifier is equipped with an oxygen supply device while maximizing the performance using the patented impregnated activated carbon filter media, and supplying clean and fresh air as well as supplying oxygen to affect the human body due to lack of oxygen. To minimize.

실내의 공기는 미세한 분진 또는 악취에 의해 오염이 되어 있고, 이러한 오염물질로 인해 인체에 미치는 영향은 상당히 크다고 할 수 있다. 산소를 공급하는 공기정화기를 이용하여 깨끗하고 신선한 공기를 요구하는 병원 등 특수한 곳에서도 사용이 가능하다.Indoor air is contaminated by fine dust or odors, and the effects on the human body due to these pollutants are quite large. The air purifier that supplies oxygen can be used in special places such as hospitals that require clean and fresh air.
