Description

습식 공기청정기Wet air purifier

본 발명은 습식 공기청정기에 관한 것으로서, 더욱 구체적으로는 미세한 그물형태의 물막필터에 오염된 공기를 통과시켜, 물막필터에 오염물질이 흡착되게 하고, 흡착된 오염물질은 세척에 의해 외부로 배출함으로써 공기의 정화가 이루어지도록 한 습식 공기청정기에 관한 것이다.The present invention relates to a wet air purifier, and more specifically, by passing contaminated air through a fine net-shaped water film filter to allow pollutants to be adsorbed to the water film filter, and the adsorbed pollutants to be discharged to the outside by washing. It relates to a wet air purifier to purify the air.

일반적으로 공기를 정화하기 위한 공기청정기는 크게 건식 공기청정기와 습식 공기청정기로 구분할 수 있다. In general, air purifiers for purifying air can be divided into dry air purifiers and wet air purifiers.

상기 건식 공기청정기는, 팬을 이용해 오염된 공기를 직물, 종이, 유리섬유 등의 여과재나 헤파필터, 활성탄 필터를 통과시켜 여과하는 여과 필터식과, 수천 볼트의 고전압을 오염된 공기에 걸어 오염 입자들이 전하를 띠게 하여 집진판에 부착하여 제거하는 전기집진식으로 나눌 수 있다. The dry air purifier is a filtration filter type in which contaminated air is filtered through a filter medium such as fabric, paper, glass fiber, hepa filter, or activated carbon filter using a fan, and a high voltage of thousands of volts is applied to the contaminated air to prevent contaminated air. It can be divided into an electric dust collection type that carries an electric charge and attaches it to the dust collection plate to remove it.

그러나 건식 여과 필터식은 오염물질을 필터로 걸러주기 때문에 정화능력이 뛰어나지만, 주기적으로 필터를 교환해야 되고, 전기집진식은 소비 전력, 기기 비용이 저렴한 장점이 있지만, 낮은 집진 효율과 오존을 발생시키는 단점이 있다. However, the dry filter type has excellent purification ability because it filters pollutants with the filter, but the filter must be replaced periodically, and the electric dust collection type has the advantage of low power consumption and low equipment cost, but low dust collection efficiency and disadvantage of generating ozone. There is this.

특히, 건식 공기청정기는, 정화된 공기가 가온되어 가벼워져서 공중으로 비산되어 실내에서 창문을 닫고 사용해야 하며, 공기 정화용량이 작고, 습기에 약하여 실외 사용에는 적합하지 않다.In particular, the dry air purifier is not suitable for outdoor use because the purified air is warmed and lightened and scattered into the air, and the window is closed indoors, and the air purification capacity is small and weak to moisture.

아울러, 건식 공기청정기를 주로 사용하는, 미세먼지와 황사가 많은 겨울과 봄은 건조하여, 가습기를 별도로 가동해야하는 실정이다. In addition, dry air purifiers are mainly used in winter and spring with a lot of fine dust and yellow dust, and the humidifier must be operated separately.

습식 공기청정기는 오염공기를 물막에 통과시키는 물막 필터식과, 물막에 접촉시키는 접촉식, 분무된 물방울에 접촉시키는 분무식으로 크게 구분할 수 있을 것이다.Wet air purifiers can be broadly divided into a water film filter type that passes contaminated air through a water film, a contact type that contacts a water film, and a spray type that contacts the sprayed water droplets.

상기 습식 접촉식은 비산물방울이 적은 장점이 있지만 오염공기와 물의 접촉표면이 적어 정화효율이 낮은 단점이 있고, 습식의 분무식은 분무 방법에 따라 정화효율을 높일 수 있지만, 분무에 많은 비용이 소요되고, 분무 물방울과 오염공기의 접촉 효율이 낮고, 분무 물방울의 제거가 곤란하여 장비효율이 낮은 단점이 있다. The wet contact method has the advantage of having fewer splashes, but has a disadvantage of low purification efficiency due to a small contact surface between contaminated air and water, and the wet spray type can increase the purification efficiency according to the spray method, but requires a lot of cost for spraying. , There is a disadvantage of low equipment efficiency due to low contact efficiency between spray water droplets and contaminated air, and difficult to remove spray water droplets.

습식 필터식은 오염공기를 물막필터에 강제로 통과시켜, 필터공극에 의하여 걸러지고 물막에 오염물질이 흡착·용해되어 정화효율이 높다.In the wet filter type, contaminated air is forcibly passed through the water film filter, filtered by the filter pores, and contaminants are adsorbed and dissolved in the water film, resulting in high purification efficiency.

특히, 습식 공기청정기는, 정화된 공기가 증발냉각 효과로 냉각되어, 무거워져서 지표면으로 가라앉아 건식 공기청정기 보다, 정화공기의 경제성이 높다. Particularly, the wet air purifier is more economical than the dry air purifier because the purified air is cooled by the evaporative cooling effect and becomes heavy and sinks to the ground.

최근에는 이러한 건식 공기청정기 문제점을 해결하기 위해 습식 공기청정기술이 연구개발 되고 있다. In recent years, research and development of wet air cleaning technology have been conducted in order to solve such a dry air purifier problem.

관련 선행기술로서, 특허 제10-1931444호(습식형 공기정화장치)에서는, 공기청정기 내부에 분사되는 물입자와 유입된 외부공기가 충돌 및 마찰로 인해 물입자 내부로 외부공기의 미세먼지 등이 흡착하여 공기를 정화하는 기술이 소개된 바 있으나, 상기 선행기술은 분무에 많은 전력이 소요되고, 상부에서 분사되는 물입자와 상부에서 유입되는 오염공기의 접촉 시간이 짧고, 분사 물입자가 쉽게 물막을 형성하여 오염물질과 물의 접촉 표면적이 적고, 기기 내부에 물을 저장하고 있어 기기내부에 미생물이 증식할 문제가 발생할 수 있다.As a related prior art, in Patent No. 10-1931444 (wet type air purifier), the water particles sprayed into the air purifier and the external air introduced into the water particles due to collision and friction, the fine dust of the external air, etc. A technology for purifying air by adsorption has been introduced, but the prior art requires a lot of power to spray, the contact time between the water particles sprayed from the top and the polluted air flowing in from the top is short, and the spray water particles are easily blocked. As a result, the contact surface area between pollutants and water is small, and water is stored inside the device, which may cause problems in which microorganisms grow inside the device.

또 다른 선행기술로서 특허 제10-1758984호(가습량 조절 기능을 구비하는 공기청정기)에서는 헤파필터에 의한 1차 필터링과 싸이클론 선회류에 의한 물입자와 접촉에 의한 2차 필터링으로 공기를 정화할 수 있는 기술이 소개된 바 있다. 그러나 상기 선행기술은 싸이클론 선회류에 의한 원심력으로 물입자가 짧은 시간에 싸이클론 벽면에 물막을 형성하여 낮은 물입자 정화 효과가 발생할 수 있어, 헤파필터에 의한 1차 필터링의 보강이 필요함을 나타낸다고 볼 수도 있다. As another prior art, Patent No. 10-1758984 (air purifier with a humidification amount control function) purifies air by primary filtering by HEPA filter and secondary filtering by contact with water particles by cyclone swirling flow. A technology that can be used has been introduced. However, the above-described prior art indicates that a low water particle purification effect may occur by forming a water film on the cyclone wall in a short time by the centrifugal force caused by the cyclone swirling flow, indicating that reinforcement of the primary filtering by the HEPA filter is necessary. You can also see.

그리고 특허 제10-1720695호(혼합식 공기청정기)에서는 미세먼지와 유해가스를 포함한 유입 공기가 고전압에 하전된 미세먼지는 전기장을 이용하여 포집되고, 습식 형태의 필터부를 이용하여 공기 내 수용성 가스를 흡착하며, 건식 형태의 필터부를 이용하여 비수용성 가스를 흡착함으로써, 공기 중에 포함된 미세먼지와 유해가스를 동시에 처리하고 가습 기능을 부가하는 기술이 소개된 바 있다.In addition, in Patent No. 10-1720695 (mixed air purifier), fine dust charged at high voltage by inlet air including fine dust and harmful gas is collected using an electric field, and water-soluble gas in the air is collected using a wet filter unit. A technology has been introduced that simultaneously processes fine dust and harmful gas contained in the air and adds a humidification function by adsorbing and adsorbing non-aqueous gas using a dry filter unit.

그러나 상기 선행기술은 미세먼지와 유해가스의 제거 효율은 뛰어나겠지만, 습식과 건식 필터부의 투과효율이 낮아 송풍기의 전기 소요량이 많은 문제가 발생할 수 있다.However, although the prior art is excellent in removal efficiency of fine dust and harmful gas, there may be a problem in that the amount of electricity required by the blower is large due to low penetration efficiency of the wet and dry filter units.

본 발명의 습식 공기청정기는 도 1에 도시한 바와 같이, 내부에 정화공간을 형성하고 일측에 공기유입부(110) 및 공기토출부(120)가 구비된 본체(100)와, 상기 본체(100)의 정화공간 내에 경사진 형태로 설치되는 물막필터(200)와, 상기 물막필터(200)의 상부에 설치되어 경사진 윗부분으로 물을 공급하여 물막필터(200)의 물막형성 및 세척이 이루어지는 세척액공급부(300)와, 상기 물막필터(200)의 상부에 설치되어 물 입자의 비산을 방지하는 비산방지그물(400)과, 상기 물막필터(200)의 경사진 하단부에 설치되어 물막필터(200)를 거친 물을 회수하여 외부로 배출하는 세척액배출부(500)와, 상기 공기토출부(120)에 설치되는 최종필터(600)로 구성된다.As shown in Fig. 1, the wet air purifier of the present invention has a main body 100 having an air inlet 110 and an air discharge unit 120 on one side and forming a purification space therein, and the main body 100 ), a water film filter 200 installed in an inclined form in the purification space of the water film filter 200, and a washing liquid installed on the upper part of the water film filter 200 to supply water to the inclined upper portion to form a water film and wash the water film filter 200 The supply unit 300, a scattering prevention net 400 installed above the water film filter 200 to prevent scattering of water particles, and a water film filter 200 installed at an inclined lower end of the water film filter 200 It is composed of a washing liquid discharge unit 500 to recover the water that has passed through and discharge it to the outside, and a final filter 600 installed in the air discharge unit 120.

그리고 본 발명의 물막필터(200)는 도 2 내지 3에 도시한 바와 같이 상부물막그물(210a), 중앙물막그물(210b), 하부물막그물(210c)로 구성되어 순서대로 포개어지는 형태로 적층되고, 가장자리에 형성된 상부그물테(220) 및 하부그물테(230)를 통해 고정되며, 세척액배출부(500) 방향의 상부그물테(220) 및 하부그물테(230)에는 복수의 배수구멍(240)이 관통형성되고, 상기 중앙물막그물(210b)은 상,하부물막그물(210a),(210c) 보다 수분포집능력이 높은 재질 또는 형태인 것을 특징으로 한다.The water film filter 200 of the present invention is composed of an upper water film 210a, a central water film 210b, and a lower water film 210c as shown in FIGS. , It is fixed through the upper net frame 220 and the lower net frame 230 formed at the edge, and the upper net frame 220 and the lower net frame 230 in the direction of the washing liquid discharge part 500 have a plurality of drain holes 240 ) Is formed through penetration, and the central water film 210b is of a material or shape having a higher moisture-collecting ability than the upper and lower water film meshes 210a and 210c.

상기 물막필터(200)는 본 발명의 핵심 구성요소로서, 유입된 오염공기의 오염물질을 흡착 제거하게 된다. 상기 물막필터(200)의 재질은 폴리에스테르, 나일론, PET, 인견, 모, 면, 마, 견 중에서 어느 하나의 재질로 이루어지며, 공극의 크기는 2001~5000㎛의 범위로 이루어지는 것이 바람직하다. The water film filter 200 is a core component of the present invention, and absorbs and removes pollutants from the introduced polluted air. The material of the water film filter 200 is made of any one of polyester, nylon, PET, silk, wool, cotton, hemp, silk, and the pore size is preferably made in the range of 2001 to 5000㎛.

상기 물막필터(200)를 이용한 오염공기의 정화과정을 간략히 설명하자면, 유입된 오염공기가 물막필터(200)의 물막을 통과하면서 오염물질이 1차 흡착되고, 물막이 터지면서 생성된 물 입자가 비산방지그물(400) 하부에서 체류하면서 오염물질을 2차 흡착하고, 최종적으로 최종필터(600)를 통과하면서 오염공기가 정화되고, 물막필터(200)와 비산방지그물(400)을 통과하면서 동시에 가습 된다.Briefly explaining the purification process of contaminated air using the water film filter 200, the pollutant is first adsorbed while the introduced contaminated air passes through the water film of the water film filter 200, and the water particles generated by the water film exploding are scattered. While staying under the prevention net 400, contaminants are adsorbed secondary, and the polluted air is finally purified while passing through the final filter 600, while passing through the water film filter 200 and the scattering prevention net 400 while simultaneously humidifying do.

일반적으로, 물막이 두꺼울수록 물막 안정성은 증가하나, 두꺼운 물막을 통과하는데 높은 공기압이 요구된다. 그러나 높은 공기압은, 물입자가 과도하게 비산되고, 송풍기의 작동부하를 유발하기 때문에 얇고 안정된 물막을 형성하는 것이 바람직하다.In general, the thicker the water film, the higher the water film stability, but a high air pressure is required to pass through the thick water film. However, it is desirable to form a thin and stable water film because the high air pressure causes excessive scattering of water particles and an operating load of the blower.

본 발명의 물막필터(200)는 이와 같이 얇고 안정된 물막을 형성하기 적합한 구조로 되어 있으며, The water film filter 200 of the present invention has a structure suitable for forming a thin and stable water film as described above,

상기 물막필터(200)는 상부물막그물(210a), 중앙물막그물(210b), 하부물막그물(210c)과 같이 3중 그물로 되어 있는데, 상기 중앙물막그물(210b)은 상,하부물막그물(210a),(210c) 보다 수분포집능력이 높은 재질 또는 형태로 되어 있다.The water film filter 200 is formed of a triple net such as an upper water film 210a, a central water film 210b, and a lower water film 210c. It is made of a material or shape having a higher moisture-collecting ability than 210a) and 210c.

즉, 바람직한 일 예로 중앙물막그물(210b)은 흡습성이 높은 섬유재질로 적용하고, 상,하부물막그물(210a),(210c)은 흡습성이 상대적으로 낮은 스테인레스 적용될 수 있으며, 또 다른 예로서 동일한 재질로 이루어지되 그물의 형태 또는 크기를 변화하여 물의 흡습성을 상대적으로 높이는 형태로 적용할 수 있다.That is, as a preferred example, the central water film 210b may be applied with a fiber material having high hygroscopicity, and the upper and lower water film meshes 210a and 210c may be applied with stainless steel having relatively low hygroscopicity. As another example, the same material However, it can be applied in a form that relatively increases the hygroscopicity of water by changing the shape or size of the net.

상기 중앙물막그물(210b)과 상,하부물막그물(210a),(210c)은 완전히 접촉되는 것이 바람직하다. 즉, 중앙물막그물(210b)에 세척액이 포집되어 물막 형성이 이루어지게 될 경우 전체적으로 균일하고 안정적으로 형성할 수 있는 이점을 갖는다. 또한, 소량의 세척액으로 물막 생성이 용이하게 이루어질 수 있으며, 중앙물막그물(210b) 자체가 배수통로 기능을 갖기 때문에 세척액이 낙수되지 않고 배수가 용이한 이점을 갖는다. It is preferable that the central water film 210b and the upper and lower water film meshes 210a and 210c are in complete contact with each other. That is, when the washing liquid is collected in the central water film 210b to form a water film, it has the advantage of uniformly and stably forming the entire water film. In addition, it is possible to easily generate a water film with a small amount of washing liquid, and since the central water film 210b itself has a function of a drain passage, the washing liquid does not drip and drains easily.

그리고 상기 물막필터(200)의 하부그물테(230)는 도 3에 도시한 바와 같이 상부그물테(220)보다 물공급방향으로 더 연장형성하여, 물막필터(200)로 흐르는 세척액이 낙수되는 것을 방지하게 된다. In addition, the lower net frame 230 of the water film filter 200 extends further in the water supply direction than the upper net frame 220 as shown in FIG. 3 to prevent the washing liquid flowing through the water film filter 200 from dripping. Will be prevented.

본 발명의 비산방지그물(400)은 물막필터(200)의 상부에 위치하는 것으로서, 1겹의 그물형태로 되어 있으며, 물막필터(200)의 물막이 터질 때 발생되는 비산 물입자의 대부분을 부착하게 된다. 즉, 물막이 터질 때 발생하는 물 입자가 비산방지그물(400)의 하부에 물방울로 맺히게 되고 맺힌 물방울이 커지게 됨에 따라 물막필터(200)로 낙하하게 된다. The scattering prevention net 400 of the present invention is located on the top of the water film filter 200, has a single-ply net shape, and attaches most of the scattering water particles generated when the water film of the water film filter 200 ruptures. do. That is, water particles generated when the water film bursts are condensed as water droplets under the scattering prevention net 400 and fall to the water film filter 200 as the formed water droplets increase.

이러한 기능을 수행하는 비산방지그물(400)은, 물막필터(200)의 물막과 비산방지그물(400)에 부착된 물방울이 세척액의 표면장력에 의하여 다시 물막을 형성할 수 없도록, 물막필터(200)와 충분한 이격거리를 확보하여야 한다.The water film filter 200 so that the water film of the water film filter 200 and the water droplets attached to the water film filter 200 cannot form a water film again due to the surface tension of the cleaning liquid. ) And sufficient separation distance must be secured.

또한, 비산방지그물(400)은 물막필터(200)의 그물과 비슷한 형상을 가지고 있고, 세척액이 비산방지그물(400)에 부분적으로 물막을 형성하고 있어 물막필터(200)와 같이 오염된 공기의 정화 기능도 일부 가지고 있다. 또한, 상기한 비산방지그물(400)은 물막필터(200)에서 세척액의 비산에 의하여 본체(100) 내부에 세척액이 튀어서 지저분해지는 것과 세척액이 증발되어 소실되는 것을 최소화한다.In addition, the anti-scattering net 400 has a shape similar to the net of the water film filter 200, and the washing liquid partially forms a water film on the anti-scattering net 400 so that contaminated air like the water film filter 200 It also has some purification functions. In addition, the anti-scattering net 400 minimizes the scattering of the washing liquid in the water film filter 200 so that the washing liquid is splashed inside the main body 100 and becomes dirty and the washing liquid is evaporated and lost.

본 발명의 최종필터(600)는 공기토출부(120)에 설치되어 자체적으로 공기여과 기능을 갖는 한편, 물 입자가 과도하게 배출되는 것을 방지하고, 본체(100) 내부로 오염물질이 유입되는 것을 방지한다. 즉, 상기 최종필터(600)는 정화된 공기에 포함되어 있는 세척액 입자를 필터링 해주는 것으로서, 최종적으로 세척액 성분이 흡착되며 적정 수분을 포함하는 청정공기가 외부로 배출되도록 하는 것이다.The final filter 600 of the present invention is installed in the air discharge unit 120 and has an air filtration function by itself, while preventing excessive discharge of water particles, and preventing pollutants from entering the main body 100. prevent. That is, the final filter 600 filters the cleaning liquid particles included in the purified air, and finally the cleaning liquid component is adsorbed and the clean air containing appropriate moisture is discharged to the outside.

본 발명의 공기유입부(110)는 외부의 오염공기가 유입되기 위한 것으로서, 본체(100) 외부에서 송풍기 등으로 가압된 오염공기가 공기유입부(110)로 유입된다. 그리고 상기 공기유입부(110)의 형태는 복수의 유입관로가 서로 다른 각도로 분지된 형태로 이루어져 물막필터(200)의 하부에 유입공기가 균일하게 공급되도록 하는 것이 바람직하다.The air inlet 110 of the present invention is for introducing external polluted air, and polluted air pressurized by a blower or the like from the outside of the main body 100 is introduced into the air inlet 110.
