Description

미세먼지 정보 제공 공기청정 시스템 및 방법Air cleaning system and method for providing fine dust information
본 발명은 미세먼지 정보 제공 공기청정 시스템 및 방법에 관한 것으로, 더욱 상세하게는 공기청정기에서 측정한 미세먼지 정보를 미세먼지 정보 서비스에 제공할 수 있는 미세먼지 정보 제공 공기청정 시스템 및 방법에 관한 것이다.The present invention relates to an air cleaning system and method for providing fine dust information, and more particularly, to an air cleaning system and method for providing fine dust information capable of providing fine dust information measured by an air purifier to a fine dust information service .
황사 또는 미세먼지 등과 같은 이물질이 대기 중에 계속해서 증가하고 있으며 호흡을 통해 인체에 흡입됨으로써 건강상에 문제를 일으키는 사례가 증가하고 있다.Foreign substances such as yellow dust or fine dust are continuously increasing in the air, and the number of cases causing health problems by being inhaled into the human body through breathing is increasing.
황사 또는 미세먼지 등의 인체 흡입을 방지하기 위해 미세 입자를 걸러내는 마스크가 다양하게 출시되고 있으나 지하철 등과 같이 밀폐된 공간에서 호흡에 불편함을 느끼는 사람들이 마스크를 착용하지 않는 경향이 있다.Masks that filter out fine particles are being released in various ways to prevent inhalation of yellow dust or fine dust, but people who feel uncomfortable breathing in an enclosed space such as subways tend not to wear masks.
밀폐된 공간에서의 마스크 착용을 강제할 수 없기 때문에 공기 중에 떠다니는 미세 입자를 필터링하여 저감 시키는 집진장치들을 지하철이나 도로변 등에 설치하여 깨끗한 공기를 사람들에게 제공하고 있다.Since it is impossible to force the wearing of a mask in an enclosed space, dust collectors that filter and reduce fine particles floating in the air are installed in subways and roadsides, etc. to provide clean air to people.
대형 공장과 같은 산업단지에서는 다량의 먼지와 미세입자들이 발생되므로 규모에 맞는 대형 집진장치를 사용하고 있으며, 일반 가정에서는 쉽게 이동하거나 휴대할 수 있는 공기청정기 등을 장소에 맞게 사용하고 있다.In industrial complexes such as large factories, a large amount of dust and fine particles are generated, so large-sized dust collectors are used.
관련된 종래 기술로는 대한민국 공개특허 제10-2019-0048654호(2019.05.09) "산업용 미세먼지 정화용 필터 집진장치"가 있으며, 3단계 다중 필터 구조로 된 필터부를 포함하고 있어 공기 중의 이물질을 용이하게 제거할 수 있다. 또한, 설치 장소에 제약이 없다는 이점이 있다.As a related prior art, there is Republic of Korea Patent Publication No. 10-2019-0048654 (2019.05.09) "Filter dust collector for industrial fine dust purification", and includes a filter unit with a three-stage multi-filter structure to easily remove foreign substances in the air can be removed In addition, there is an advantage that there is no restriction on the installation location.
또한, 대한민국 등록특허 제10-2065773호(2020.01.14) "야외용 미세먼지 저감장치"는 야외에 설치되기는 하나, 작업현장의 휴식장소, 대중교통 및 신호를 기다리는 장소에 설치하여 청정 공기를 제공할 수 있는 이점이 있다.In addition, the Republic of Korea Patent Registration No. 10-2065773 (Jan. 14, 2020) "Outdoor Fine Dust Reduction Device" is installed outdoors, but it is installed in a resting place at the work site, public transportation, and a place waiting for a signal to provide clean air. There are advantages that can be
그러나, 공개특허 및 등록특허에 사용되는 미세입자를 걸러내는 필터는 장기간 사용하게 되면 필터 외면에 미세입자들이 흡착되어 필터 기능을 저하시키고 수명이 다된 필터를 자주 교체해야 하는 문제점이 있다.However, the filter for filtering fine particles used in the published patents and registered patents has a problem in that, when used for a long period of time, the fine particles are adsorbed on the outer surface of the filter, thereby reducing the filter function and frequently replacing the filter whose lifespan has expired.
또한, 공공 장소에 설치된 다수의 공기청정기를 유지보수하기 위해 담당 인력이 설치 장소를 찾아 다니며 필터 상태를 확인하고 장비 운영 상태를 점검하여야 하기 때문에 시간과 비용이 많이 소비되는 문제점이 있다.In addition, in order to maintain a number of air purifiers installed in public places, there is a problem in that a large amount of time and money is consumed because a person in charge has to visit the installation site to check the filter status and to check the equipment operation status.
또한, 공공 장소에 접근하는 일반 대중이 미세먼지 상태를 사전에 인지하고 효율적으로 대응할 수 있도록 공공 장소에 설치된 다수의 공기청정기에서 측정된 미세먼지 정보를 일반 대중에게 제공할 필요성이 있다.In addition, there is a need to provide the general public with information on fine dust measured by a number of air purifiers installed in public places so that the general public accessing public places can recognize the state of fine dust in advance and respond efficiently.

도 2 내지 도 4를 참조하면, 미세먼지 저감장치(10)는 유입부(110), 제1 미세먼지 측정부(120), 집진부(130), 먼지 수납부(140), 제2 미세먼지 측정부(150), 토출부(160), 제어부(170) 및 통신부(180)를 포함할 수 있다.2 to 4 , the fine dust reduction device 10 includes an inlet 110 , a first fine dust measuring unit 120 , a dust collecting unit 130 , a dust receiving unit 140 , and a second fine dust measuring unit. It may include a unit 150 , a discharge unit 160 , a control unit 170 , and a communication unit 180 .
유입부(110)는 외부로부터 기체가 흡입되어 집진부(130)로 연결되는 배관을 포함할 수 있다. 외부로부터 흡입되는 유입 기체는 미세먼지 저감장치(10)가 설치되는 위치에 따라 달라질 수 있다. 예를 들어, 미세먼지 저감장치(10)가 공공장소에 설치되는 경우 유입 기체는 공공장소의 내부 공기를 포함할 수 있다. 또는, 미세먼지 저감장치(10)가 공장 등의 설비로부터 배출되는 배출가스의 미세먼지를 저감시키기 위해 특정 설비의 가스 분출구에 설치되는 경우 유입 기체는 배출가스를 포함할 수 있다.The inlet 110 may include a pipe through which gas is sucked from the outside and connected to the dust collecting unit 130 . The inflow gas sucked from the outside may vary depending on the location where the fine dust reduction device 10 is installed. For example, when the fine dust reduction device 10 is installed in a public place, the inflow gas may include internal air of the public place. Alternatively, when the fine dust reduction device 10 is installed at a gas outlet of a specific facility to reduce fine dust of exhaust gas discharged from facilities such as a factory, the inflow gas may include the exhaust gas.
제1 미세먼지 측정부(120)는 유입부(110)를 통해 흡입되는 유입 기체의 미세먼지 농도를 측정할 수 있다.The first fine dust measuring unit 120 may measure the fine dust concentration of the inlet gas sucked through the inlet 110 .
제1 미세먼지 측정부(120)는 광산란 방식을 이용하여 미세먼지의 양을 측정할 수 있다. 광산란 방식이란, 산란광의 양을 측정하고 그 값으로부터 입자상 물질의 농도를 구하는 방법이다. The first fine dust measurement unit 120 may measure the amount of fine dust using a light scattering method. The light scattering method is a method of measuring the amount of scattered light and obtaining the concentration of particulate matter from the value.
구체적으로, 대기중에 부유하고 있는 입자상 물질에 빛을 조사하면 입자상 물질에 의하여 빛이 산란한다. 이 경우, 물리적 성질이 동일한 입자상 물질에 빛을 조사하면 산란광의 양은 질량 농도에 비례한다는 원리를 이용한 측정 방법이다.Specifically, when light is irradiated to the particulate matter suspended in the atmosphere, the light is scattered by the particulate matter. In this case, it is a measurement method using the principle that the amount of scattered light is proportional to the mass concentration when light is irradiated to a particulate material having the same physical properties.
제1 미세먼지 측정부(120)는 입자 분리기(미도시) 및 광산란 센서(미도시)를 포함할 수 있다. The first fine dust measurement unit 120 may include a particle separator (not shown) and a light scattering sensor (not shown).
입자 분리기는 유입되는 미세 입자에 급격한 회전을 인가하여 무거운 질량의 입자를 분리할 수 있다. 구체적으로 입자 분리기가 유입되는 미세먼지에 급격한 회전을 인가하면, 질량이 큰 입자는 원심력에 의해 공기가 회전하는 흐름을 벗어나 포집되고, 가벼운 입자는 공기의 흐름을 따라 이동하게 된다.The particle separator can separate particles of heavy mass by applying a sharp rotation to the incoming fine particles. Specifically, when the particle separator applies a sharp rotation to the incoming fine dust, the particles with large mass are captured outside the air rotating flow by centrifugal force, and the light particles move along the air flow.
예를 들어, 입자 분리기는 미리 설정된 입자의 밀도를 기준으로 미세먼지(PM 10) 또는 초미세먼지(PM 2.5)를 분리해낼 수 있다.For example, the particle separator may separate fine dust (PM 10) or ultrafine dust (PM 2.5) based on a preset particle density.
입자 분리기는 입자의 분리 능력을 향상시키기 위하여 내부의 습기를 제거할 수 있는 습기 제거기를 포함할 수 있다.The particle separator may include a moisture eliminator capable of removing moisture therein to improve particle separation capability.
광산란 센서는 입자에 광을 비추면 회절, 굴절 및 반사되는 광산란 방식을 이용하여 입자의 농도를 측정할 수 있다. 광산란 센서는 입자의 크기에 따라 산란되는 광이 달라지는 원리를 이용하여 입자의 농도를 측정할 수 있다.The light scattering sensor may measure the concentration of the particles by using a light scattering method in which light is irradiated to the particles, diffraction, refraction, and reflection. The light scattering sensor can measure the concentration of particles by using the principle that scattered light varies depending on the size of the particles.
구체적으로, 광산란 센서는 유입되는 입자에 의해 산란되는 광을 센싱하여 크기별 입자의 수를 카운트하여 미세먼지의 농도를 산출할 수 있다.Specifically, the light scattering sensor may calculate the concentration of fine dust by sensing the light scattered by the incoming particles and counting the number of particles by size.
일 실시예에서, 제1 미세먼지 측정부(120)는 상대적으로 크기가 다른 두 개의 입자 크기별 농도를 측정하기 위하여, 두 개의 입자 분리기 및 두 개의 광산란 센서를 포함할 수 있다. In an embodiment, the first fine dust measurement unit 120 may include two particle separators and two light scattering sensors to measure the concentration of two particles having relatively different sizes.
일 실시예에서, 제1 미세먼지 측정부(120)는 미세 입자 (이하 PM 10 미세먼지) 및 초미세 입자(이하 PM 2.5 미세먼지)의 농도를 측정할 수 있으나, 이에 한정되는 것은 아니며 필요에 따라 다양한 크기의 미세 입자를 측정할 수 있도록 구성될 수 있다.In an embodiment, the first fine dust measurement unit 120 may measure the concentrations of fine particles (hereinafter PM 10 fine dust) and ultrafine particles (hereinafter PM 2.5 fine dust), but is not limited thereto. Accordingly, it can be configured to measure fine particles of various sizes.
예를 들어, 제1 미세먼지 측정부(120)는 PM 10 미세먼지 및 PM 2.5 미세먼지(즉, 초미세먼지)의 농도를 측정하기 위하여, PM 10 미세먼지를 분리할 수 있는 제1 입자 분리기와 제1 광산란 센서, PM 2.5 미세먼지를 분리할 수 있는 제2 입자 분리기와 제2 광산란 센서를 포함할 수 있다.For example, the first fine dust measurement unit 120 is a first particle separator capable of separating PM 10 fine dust in order to measure the concentrations of PM 10 fine dust and PM 2.5 fine dust (ie, ultra-fine dust). and a first light scattering sensor, a second particle separator capable of separating PM 2.5 fine dust, and a second light scattering sensor.
제2 입자 분리기는 PM 10 미세먼지보다 작은 PM 2.5 미세먼지를 측정하기 위하여 제1 입자 분리기 보다 원통 크기가 작을 수 있다. 즉, 제2 입자 분리기는 선회류 반경(즉, 회전하는 반경)이 제1 입자 분리기 보다 작게 형성될 수 있다.The second particle separator may have a cylindrical size smaller than that of the first particle separator in order to measure PM 2.5 fine particles smaller than PM 10 fine particles. That is, the second particle separator may have a radius of swirl (ie, a radius of rotation) smaller than that of the first particle separator.
이때, 제2 광산란 센서는 제1 광산란 센서와 동일한 구성을 포함할 수 있으나, 이에 한정되는 것은 아니며, 필요에 따라 다른 구성을 포함할 수 있다.In this case, the second light scattering sensor may include the same configuration as the first light scattering sensor, but is not limited thereto, and may include a different configuration as necessary.

In one embodiment, the filter 131 may include a bag-shaped bag filter. Bag filters can trap airborne particles (eg, 0.1-100 μm fine particles) using a bag-shaped filter fabric.
다른 실시예에서, 필터(131)는 헤파 필터가 주머니 모양으로 형성된 백 필터를 포함할 수 있다. 구체적으로, 필터(131)는 헤파 필터가 상부가 개방되고, 하부가 막힌 원통형 주머니 모양으로 형성된 백 필터를 포함할 수 있다. 헤파 필터는 등급에 따라 차이가 있으나, 일반적으로 0.3 μm 크기의 입자를 약 99.97% 이상 걸러낼 수 있다.In another embodiment, the filter 131 may include a bag filter in which the HEPA filter is formed in a bag shape. Specifically, the filter 131 may include a bag filter in which the HEPA filter is formed in a cylindrical bag shape with an open top and a closed bottom. HEPA filters differ depending on the grade, but in general, they can filter out about 99.97% or more of particles with a size of 0.3 μm.
일 실시예에서, 유입 기체는 필터(131)가 설치되어 있는 필터 하우징(135) 내부로 유입되어 필터(131)를 통과하여 흐를 수 있다. 유입 기체는 일 방향이 개방된 원통형 주머니 형태(즉, 백필터 형태)의 필터(131) 외면으로부터 내면 방향으로 통과하면서, 유입 기체에 포함되어 있는 미세먼지가 필터(131)의 외면에 부착되어 미세먼지가 저감될 수 있다. 다시 말해, 유입 기체는 원통형 주머니 형태의 필터(131) 외면으로부터 내면 방향으로 통과하여 개방된 상부 방향으로 흐를 수 있다. In one embodiment, the inlet gas may be introduced into the filter housing 135 in which the filter 131 is installed, and may flow through the filter 131 . As the inflow gas passes from the outer surface to the inner surface of the filter 131 in the form of a cylindrical bag (that is, in the form of a bag filter) that is open in one direction, the fine dust contained in the inlet gas is attached to the outer surface of the filter 131 to create fine particles. Dust can be reduced. In other words, the inlet gas may flow from the outer surface of the filter 131 in the form of a cylindrical bag to the inner surface and flow in an open upper direction.
따라서, 필터(131)는 시간이 경과함에 따라 외면에 미세먼지가 흡착되어 먼지 케이크를 형성할 수 있다.Accordingly, fine dust may be adsorbed to the outer surface of the filter 131 over time to form a dust cake.
기압 측정기(134)는 필터(131)를 통과하는 기체의 압력을 측정할 수 있다. 기압 측정기(134)는 필터(131)를 통과하는 기체의 압력인 필터 통과 공기압을 측정할 수 있다. 기압 측정기(134)는 필터(131)를 통과하는 기체의 압력을 측정하기 위해 유입부(110)와 집진부(130) 사이에 설치될 수 있다. 예를 들어, 기압 측정기(134)는 유입 기체가 필터 하우징(135)으로 집입하는 길목에 설치될 수 있다.The barometric pressure meter 134 may measure the pressure of the gas passing through the filter 131 . The barometric pressure meter 134 may measure the air pressure passing through the filter, which is the pressure of the gas passing through the filter 131 . The barometric pressure meter 134 may be installed between the inlet 110 and the dust collector 130 to measure the pressure of the gas passing through the filter 131 . For example, the barometric pressure meter 134 may be installed on a path through which the inlet gas collects into the filter housing 135 .
제2 미세먼지 측정부(150)는 집진부(130)를 통과하여 미세먼지가 제거된 토출 기체의 미세먼지 농도를 측정할 수 있다. 제2 미세먼지 측정부(150)는 제1 미세먼지 측정부(120)와 실질적으로 동일한 구성을 포함할 수 있는 바, 중복되는 설명은 생략할 수 있다.The second fine dust measuring unit 150 may measure the fine dust concentration of the discharged gas from which fine dust has been removed by passing through the dust collecting unit 130 . The second fine dust measuring unit 150 may include substantially the same configuration as the first fine dust measuring unit 120 , and thus overlapping descriptions may be omitted.
도 3의 (a)는 압축공기 분사기(132)의 작동을 설명하기 위한 개념도이다. 도 3의 (a)를 참조하면, 압축공기 분사기(132)는 필터(131)의 개방된 상부로부터 필터(131) 내면 방향으로 압축공기를 분사할 수 있다.3 (a) is a conceptual diagram for explaining the operation of the compressed air injector (132). Referring to FIG. 3A , the compressed air injector 132 may inject compressed air from the open top of the filter 131 toward the inner surface of the filter 131 .
압축공기 분사기(132)는 공기가 흐르는 통로의 직경이 공기가 유입되는 입구의 직경 보다 좁은 벤투리 형태의 배관을 통해 압축 공기를 공급받을 수 있다. 압축공기 분사기(132)는 고압의 압축공기를 필터(131) 내부로 분사할 수 있는 노즐을 포함할 수 있다. The compressed air injector 132 may receive compressed air through a venturi-type pipe in which a diameter of a passage through which air flows is narrower than a diameter of an inlet through which air is introduced. The compressed air injector 132 may include a nozzle capable of injecting high-pressure compressed air into the filter 131 .
압축공기 분사기(132)는 원통형 주머니 형태의 필터(131) 내면으로부터 외면 방향으로 고압의 압축공기를 분사할 수 있다. 압축공기 분사기(132)로부터 분사된 압축공기는 미세먼지를 포함하는 유입 기체와 역방향으로 흘러 필터(131) 외면에 부착된 미세먼지 및 필터(131) 내부에 누적된 미세먼지를 필터(131)로부터 분리시킬 수 있다.The compressed air injector 132 may inject high-pressure compressed air from the inner surface of the filter 131 in the form of a cylindrical bag toward the outer surface. Compressed air injected from the compressed air injector 132 flows in the opposite direction to the inflow gas containing fine dust, and the fine dust attached to the outer surface of the filter 131 and the fine dust accumulated inside the filter 131 are removed from the filter 131. can be separated.

압축공기 분사기(132)가 압축 공기를 분사하는 기준이 되는 미세먼지 기준값 및 공기압 기준값은 필터(131)의 성능, 수명 또는 미세먼지 정보 제공 공기청정 시스템이 설치된 환경 등을 고려하여 미리 정해질 수 있다.The fine dust reference value and the air pressure reference value, which are the criteria for the compressed air injector 132 to inject compressed air, may be predetermined in consideration of the performance, lifespan, or the environment in which the fine dust information providing air cleaning system of the filter 131 is installed. .
필터(131)의 수명이 감소함에 따라, 토출 기체의 미세먼지 농도가 증가하고, 필터 통과 공기압이 상승하는 것에 대응하여 미세먼지 기준값 및 공기압 기준값 역시 변경될 필요성이 있으며, 일정 기준에 따라 증가하도록 보정하는 것이 바람직하다.As the lifespan of the filter 131 decreases, the fine dust concentration of the discharged gas increases, and the fine dust reference value and the air pressure reference value also need to be changed in response to an increase in the air pressure passing through the filter, and are corrected to increase according to a certain standard It is preferable to do
일 실시예에서, 미세먼지 기준값은 압축공기 분사기(132)가 필터(131)에 압축공기를 분사한 직후 측정된 토출 기체의 미세먼지 농도의 변화에 기초하여 변경될 수 있다.In an embodiment, the fine dust reference value may be changed based on a change in the fine dust concentration of the discharged gas measured immediately after the compressed air injector 132 injects compressed air to the filter 131 .
예를 들어, 압축공기 분사기(132)가 필터(131)에 압축공기를 N회차 분사한 경우, 미세먼지 기준값은 N-1 회차에 압축공기를 분사한 직후 측정된 토출 기체의 미세먼지 농도 대비 N 회차에 압축공기를 분사한 직후 측정된 토출 기체의 미세먼지 농도의 증가율을 기초로 증가될 수 있다. For example, when the compressed air injector 132 injects compressed air to the filter 131 N times, the fine dust reference value is N compared to the fine dust concentration of the discharged gas measured immediately after the compressed air is sprayed N-1 times. It may be increased based on the increase rate of the fine dust concentration of the discharged gas measured immediately after the compressed air is injected into the cycle.
일 실시예에서, 미세먼지 기준값은 압축공기 분사기(132)가 필터(131)에 압축공기를 N-1 회차에 분사한 직후 측정된 토출 기체의 미세먼지 농도 대비 압축공기 분사기(132)가 필터(131)에 압축공기를 N 회차에 분사한 직후 측정된 토출 기체의 미세먼지 농도의 증가율을 기초로 증가될 수 있으며, 아래 식으로 표현될 수 있다.In one embodiment, the fine dust reference value is the compressed air injector 132 compared to the fine dust concentration of the discharged gas measured immediately after the compressed air injector 132 injects the compressed air to the filter 131 in N-1 times. 131) can be increased based on the increase rate of the fine dust concentration of the discharged gas measured immediately after the compressed air is injected N times, and it can be expressed by the following formula.
