By minimizing measurement errors and controlling the opening and closing of the first control valve provided in the control line while diverging the flow rate sucked at a constant velocity into the measurement line and the control line, a constant constant velocity suction flow required for the particle size separation device is introduced into the measurement line. The present invention relates to a continuous automatic measurement device for fine dust of chimney exhaust gas that enables continuous and automatic measurement of fine dust in exhaust gas.
일반적으로 화석 연료를 태워서 그 화력으로 발전하는 화력 발전소, 산업 폐기물이나 일반 생활 쓰레기를 소각 처리하는 소각장 등에서는 인체에 유해한 다양한 종류의 배출가스가 배출된다. 이러한 유해 물질은 입자상 물질, 할로겐족가스와, 질소산화물, 아황산가스, 일산화탄소, 염화수소, 암모니아, 등의 연소 가스를 포함할 수 있다. 이와 같은 유해 물질은 인체에 흡수된 후에 축적이 되면 각종 질병을 유발할 뿐만 아니라 자연 환경에도 나쁜 영향을 미치는 것으로 각종 조사 및 실험을 통해 입증되고 있다.In general, various types of exhaust gases harmful to the human body are discharged in a thermal power plant that burns fossil fuels to generate power using the thermal power, or an incinerator that incinerates industrial waste or general household waste. Such harmful substances may include particulate matter, halogenated gas, and combustion gases such as nitrogen oxide, sulfurous acid gas, carbon monoxide, hydrogen chloride, ammonia, and the like. When such harmful substances are absorbed and accumulated in the human body, they not only cause various diseases, but also adversely affect the natural environment, which has been proven through various investigations and experiments.
이러한 이유로 전세계적으로 소각장 및 화석 연료를 사용하는 사업장의 경우에는 강력한 법에 의해 유해 물질의 배출량을 규제 받고 있으며, 국내에서도 환경부 고시를 통해서 배출가스에 포함되는 유해 물질의 배출량을 제한하고 있다. For this reason, in the case of incinerators and businesses that use fossil fuels around the world, the emission of harmful substances is regulated by strong laws, and even in Korea, the emission of harmful substances included in the emission gas is limited through a notification from the Ministry of Environment.
지금까지는 화력 발전소, 산업용 공장 등의 굴뚝에서 배출되는 배출가스에 포함된 유해 물질의 측정을 위해 총입자상 물질(TSP; Total Suspended Particles)를 측정 및 관리하는 방식을 사용해왔지만, 정작 인체에 매우 유해한 피해를 초래하는 미세먼지(PM10) 또는 초미세먼지(PM2.5)에 대해서는 정확하게 그리고 신뢰성 있게 측정하지 못하고 있는 실정이다. Until now, a method of measuring and managing Total Suspended Particles (TSP) has been used to measure harmful substances contained in exhaust gases emitted from chimneys such as thermal power plants and industrial plants, but it is very harmful to the human body. It is not possible to accurately and reliably measure fine dust (PM10) or ultrafine dust (PM2.5) that causes a problem.
게다가, 미세먼지의 농도 측정은 채취의 특성상 장시간 채취가 전제되어야 하지만, 그러한 장시간 동안에 수시로 변화하는 배출가스의 유속 특성으로 인해 가스 샘플링 단계에서의 등속유량조건과 입경 분리 단계에서의 정속유량조건을 동시에 충족시키는 방법, 장치, 또는 시스템이 관련 분야에서 지금까지는 개발이 매우 미흡한 실정이다. In addition, the concentration of fine dust must be collected for a long time due to the characteristics of the collection, but due to the characteristics of the flow velocity of the exhaust gas that changes frequently during such a long time, the constant velocity flow condition in the gas sampling step and the constant velocity flow condition in the particle size separation stage are simultaneously A method, apparatus, or system to meet has so far been very poorly developed in the related field.
미세먼지를 측정하기 위해서는 등속 흡인이 필수적이고 등속 흡인의 공정에서 미세먼지를 분리 측정하기 위해서는 입경분리장치를 통과시켜 입자를 분리해야 하지만, 입경분리장치에서는 정속흡인유량을 흡인해야만 하는 서로 모순된 조건이 하나의 공정에서 존재하게 된다.In order to measure fine dust, constant velocity suction is essential, and in order to separate and measure fine dust in the constant velocity suction process, particles must be separated by passing through a particle size separation device, but in a particle size separation device, a constant velocity suction flow rate must be sucked. It exists in this one process.

The present invention is to solve the above problems, the present invention is a chimney exhaust gas that minimizes the error in the measurement of fine dust by sucking through a suction nozzle at a constant flow rate equal to the flow rate of the exhaust gas when collecting a sample of the exhaust gas It is an object to provide a continuous automatic measuring device for fine dust.
또한, 본 발명은 흡인된 배출가스 시료를 측정라인과 제어라인으로 분기함에 있어, 제어라인에 구비된 제1 제어밸브의 개폐를 제어함으로써 측정라인에 구비된 입경분리장치에 정속 유량이 공급되도록 하고, 그에 따라 미세먼지의 정밀한 분리 및 연속자동측정을 가능하게 하는 굴뚝 배출가스의 미세먼지 연속자동측정장치를 제공하는 것을 목적으로 한다.In addition, the present invention controls the opening and closing of the first control valve provided in the control line in branching the sucked exhaust gas sample into the measurement line and the control line so that a constant speed flow rate is supplied to the particle diameter separation device provided in the measurement line.

As shown in Fig. 1, the apparatus 10 for continuous automatic measurement of fine dust of the flue gas according to an embodiment of the present invention includes a sample collection unit 100, a sample branch/combination unit 200, and a pretreatment unit. It may be composed of 300, a gas measurement unit 400, a constant velocity suction control unit 500, a controller 600, and the like. For reference, the elements 100, 200, 300, 400, 500, 600 shown in FIG. 1 are the operation, function, etc. of the continuous automatic measurement device 10 for fine dust of the flue gas according to an embodiment of the present invention. It will be apparent that it corresponds to an exemplary element for explaining, and therefore additional elements (eg, a power supply unit, an alarm unit, a monitoring unit, etc.) not shown in FIG. 1 may be further provided.
시료 채취부(100)의 적어도 일부 영역은 굴뚝(1) 내에 배치되어, 굴뚝(1) 내 배출가스 시료를 채취할 수 있다. 참고로, 미세먼지의 측정을 위해 배출가스 시료를 채취함에 있어 등속 흡인이 매우 중요한데, 왜냐하면 배출가스를 채취함에 있어 배출가스 유속보다 더 빠른 속도로 흡인하게 되면 주변의 미세입자를 우선 흡인하게 되어 결과치가 실제보다 더 낮은 농도로 나타나게 되고, 배출가스 유속보다 더 낮은 속도로 흡인하게 되면 관성력에 의해 큰 입자가 우선 흡인하게 되어 결과치가 실제보다 더 높은 농도로 측정되기 때문이다. 시료 채취부(100)에서의 이러한 등속흡인유량조건은 컨트롤러(600)로부터 출력되는 제어 신호(i520 및/또는 i530)에 따라 등속흡인제어부(500)에 의해 구현될 수 있으며, 이에 대해서는 이하에서 보다 상술하기로 한다. At least a portion of the sample collection unit 100 is disposed in the chimney 1 to collect a sample of exhaust gas in the chimney 1. For reference, in collecting exhaust gas samples for the measurement of fine dust, constant velocity suction is very important, because when the exhaust gas is sucked at a faster rate than the exhaust gas flow rate, the surrounding fine particles are first sucked. This is because when is shown at a lower concentration than the actual concentration, and when suction is performed at a lower velocity than the exhaust gas flow rate, large particles are first sucked by the inertial force, and the result is measured at a higher concentration than the actual value. This constant velocity suction flow condition in the sample collection unit 100 may be implemented by the constant velocity suction control unit 500 according to the control signals i 520 and/or i 530 output from the controller 600, and for this It will be described in more detail in the following.

도 2는 본 발명의 일 실시예에 따른 굴뚝 배출가스의 미세먼지 연속자동측정장치(10)의 세부 구성도이다. 도 1과 관련하여 이미 기술한 바와 같이, 본 발명의 일 실시예에 따른 굴뚝 배출가스의 미세먼지 연속자동측정장치(10)는 적어도 일부 영역이 굴뚝(1)의 내부에 배치되는 시료 채취부(100)와 굴뚝(1)의 외부에 배치되는 시료 분기/결합부(200), 전처리부(300), 가스측정부(400), 등속흡인제어부(500), 컨트롤러(600)로 구성될 수 있다. 2 is a detailed configuration diagram of a continuous automatic measurement device 10 for fine dust of a chimney exhaust gas according to an embodiment of the present invention. As already described with reference to FIG. 1, the apparatus 10 for continuously measuring fine dust of flue gas according to an embodiment of the present invention includes at least a part of a sample collecting unit disposed inside the chimney 1 ( 100) and a sample branch/combination unit 200 disposed outside the chimney 1, a pretreatment unit 300, a gas measurement unit 400, a constant velocity suction control unit 500, and a controller 600. .
시료 채취부(100)는 굴뚝 내 배출가스 시료를 채취하도록 구성될 수 있고, 도 2에 도시되는 바와 같이 시료 채취부(100)는 흡인관(110)과, 피토관(120)과, 온도계(130)와, 가열 장치(140), 등으로 구성될 수 있다. The sample collection unit 100 may be configured to collect a sample of exhaust gas in the chimney, and as shown in FIG. 2, the sample collection unit 100 includes a suction tube 110, a Pitot tube 120, and a thermometer 130. Wow, it may be composed of a heating device 140, and the like.
참고로, 배출가스 내 미세먼지 등의 입자성 물질을 분석하고 측정하기 위해서는 굴뚝 등 배출 원점에서 배출가스를 채취하는 것이 바람직한데, 이는 굴뚝 내 배출가스의 미세먼지 밀도 조건이 미세먼지의 밀도가 균일한 일반 대기와는 매우 상이하기 때문이다. 따라서, 굴뚝 등 배출 원점에서 벗어난 배출가스는 일반 대기와 혼합되어 밀도가 낮아지므로 배출가스가 일반 대기와 혼합되기 이전에 굴뚝 등의 배출 원점에서 시료 채취를 수행하는 것이 바람직하다. For reference, in order to analyze and measure particulate matter such as fine dust in the exhaust gas, it is desirable to collect the exhaust gas from the discharge origin, such as a chimney.This is because the fine dust density condition of the exhaust gas in the chimney is uniform. This is because it is very different from a normal atmosphere. Therefore, since the exhaust gas that deviates from the emission origin such as the chimney is mixed with the general atmosphere and the density is lowered, it is preferable to perform sampling at the emission origin such as the chimney before the exhaust gas is mixed with the general atmosphere.
도 2에서는 굴뚝(1) 내 배출가스 유속을 측정하기 위한 엘리먼트로서 국내공정시험법의 기준에 부합하는 피토관(120; pitot tube)을 예시적으로 도시한다. 참고로, 피토관(120)은 흐르는 유체 내부에 설치되어 유체의 속도를 측정하도록 구성되는 장치로서, 피토관(120) 내/외부의 압력 차이가 유체 속도의 제곱과 비례하는 법칙, 즉 베르누이의 법칙(Bernoulli's equation)에 의거 유체의 속도를 구할 수 있다. In FIG. 2, as an element for measuring the exhaust gas flow rate in the chimney 1, a pitot tube 120 meeting the standards of the domestic process test method is illustrated as an example. For reference, the Pitot tube 120 is a device installed inside the flowing fluid and configured to measure the velocity of the fluid, and a law in which the pressure difference inside/outside the Pitot tube 120 is proportional to the square of the fluid velocity, that is, Bernoulli's law ( The velocity of the fluid can be obtained according to Bernoulli's equation.
본 발명의 다른 실시예에 따르면, 피토관(120)을 대체하여 굴뚝용 질량유량계(MFM; mass flow meter)을 활용하여 굴뚝(1) 내 배출가스 유속을 측정하는 것도 가능하다. According to another embodiment of the present invention, it is possible to measure the exhaust gas flow rate in the chimney 1 using a mass flow meter (MFM) for a chimney in place of the Pitot tube 120.
흡인관(110)은 그 일단에 굴뚝(1) 내 적어도 일부 영역에 배치되는 흡인 노즐(111)이 구비되고, 그 타단이 시료 분기/결합부(200)와, 보다 구체적으로는 분리매니폴드(210)와 결합되며, 흡인관(110)을 통해 굴뚝 내 배출가스 시료가 시료 분기/결합부(200)로 전달될 수 있다. 여기서, 흡인 노즐(111)의 단면적은 입경분리장치(221)에 필요한 정속 유량을 초과하는 유량으로 배출가스 시료를 흡인할 수 있도록 치수 설계되는 것을 특징으로 한다.The suction pipe 110 is provided with a suction nozzle 111 disposed in at least a portion of the chimney 1 at one end thereof, and the other end thereof is a sample branch/combination part 200 and, more specifically, a separation manifold 210 ) And the exhaust gas sample in the chimney may be delivered to the sample branch/coupler 200 through the suction pipe 110. Here, the cross-sectional area of the suction nozzle 111 is characterized in that it is dimensionally designed to suck the exhaust gas sample at a flow rate exceeding the constant flow rate required for the particle size separation device 221.
예를 들어, 굴뚝(1)의 설계 용량, 굴뚝(1)의 가동 정보(유량, 유속, 등), 등에 기초하여 입경분리장치(221)가 필요로 하는 정속 유량을 초과하는 유량으로 배출가스 시료를 등속 흡인할 수 있도록 흡인 노즐(111)의 단면적이 결정될 수 있고, 입경분리장치(221)가 PM10 임팩터(impactor, 221a) 및 PM2.5 임팩터(221b)로 구성되는 캐스케이드-임팩터(cascade impactor)로 구현되는 경우에 그러한 캐스케이드-임팩터에 필요한 정속 유량은 16.67 ℓ/min일 수 있다. For example, based on the design capacity of the chimney 1, operation information (flow rate, flow rate, etc.) of the chimney 1, the exhaust gas sample at a flow rate exceeding the constant flow rate required by the particle size separation device 221 The cross-sectional area of the suction nozzle 111 may be determined so that the suction nozzle 111 can be sucked at a constant velocity, and the particle diameter separation device 221 is a cascade impactor composed of a PM10 impactor 221a and a PM2.5 impactor 221b. In the case of implementation, the constant flow rate required for such a cascade-impacter may be 16.67 l/min.
참고로, 이하의 본 명세서에서는 PM10 임팩터(221a)와 PM2.5 임팩터(221b)가 직렬로 연결된 입경분리장치(221)를 기술하고 있지만, 본 발명의 다른 실시예에서는 입경분리장치(221)가 PM10 임팩터(221a)와 PM2.5 임팩터(221b) 중 어느 하나만을 구비할 수도 있거나, 또는 추가의 임팩터, 예를 들어 PM1.0 임팩터가 더 구비될 수도 있다.For reference, in the following specification, the particle size separation device 221 in which the PM10 impactor 221a and the PM2.5 impactor 221b are connected in series is described, but in another embodiment of the present invention, the particle size separation device 221 is Only one of the PM10 impactor 221a and the PM2.5 impactor 221b may be provided, or an additional impactor, for example, a PM1.0 impactor may be further provided.
따라서, 본 발명에 따르면 굴뚝(1)의 설계 용량 등에 기초하여 입경분리장치(221)가 필요로 하는 정속 유량을 초과하는 유량으로 배출가스 시료를 등속 흡인하도록 흡인 노즐(111)의 단면적이 결정될 수 있고, 그에 따라 분리매니폴드(210)에서의 분기 동작에 의해 입경분리장치(221)에는 입경 분리에 필요한 정속 유량이 안정적으로 공급될 수 있다. Therefore, according to the present invention, the cross-sectional area of the suction nozzle 111 can be determined to suck the exhaust gas sample at a constant velocity at a flow rate exceeding the constant velocity flow rate required by the particle size separation device 221 based on the design capacity of the chimney 1, etc. Accordingly, a constant flow rate required for particle size separation can be stably supplied to the particle size separation device 221 by a branching operation in the separation manifold 210.
예를 들어, 배출구 온도 120℃ ~ 180℃ 범위에서 배출구 유속이 5m/sec ~ 10 m/sec로 가동되는 발전소의 경우에 흡인 노즐의 구경을 10mm로 선정하면 등속흡인유량(참고로, 공정시험법에 따르면 95% 내지 110%의 허용범위)이 17.5 ℓ/min 내지 34 ℓ/min로 설정될 수 있고, 이러한 조건에서 배출구 유속을 8.5m/sec이고 배출 온도를 150℃로 하면 등속흡인유량이 29.2ℓ/min로 산출될 수 있다. 따라서, 배출구 유속 8.5m/sec, 배출 온도 150℃ 및 노즐 구경 10mm의 조건으로 시료 채취부(100)에서 29.2 ℓ/min의 등속흡인유량이 발생하면, 등속흡인제어부(500)의 제어에 따라 측정라인(220)에 16.67 ℓ/min의 정속흡인유량이 흐르게 하고 나머지는 제어라인(230)을 통해 바이패스되도록 하는 것을 특징으로 한다. 이에 대해서는 이하에서 다시 후술하기로 한다. For example, in the case of a power plant operating at an outlet flow rate of 5 m/sec to 10 m/sec in the range of 120°C to 180°C, if the diameter of the suction nozzle is selected as 10 mm, the constant velocity suction flow rate (for reference, process test method According to the permissible range of 95% to 110%) can be set to 17.5 ℓ/min to 34 ℓ/min, under these conditions, if the outlet flow rate is 8.5 m/sec and the discharge temperature is 150°C, the constant velocity suction flow rate is 29.2 It can be calculated as ℓ/min. Therefore, when a constant velocity suction flow of 29.2 L/min occurs in the sample collection unit 100 under the conditions of an outlet flow velocity of 8.5 m/sec, a discharge temperature of 150° C., and a nozzle diameter of 10 mm, the measurement according to the control of the constant velocity suction control unit 500 It is characterized in that the constant velocity suction flow rate of 16.67 L/min flows through the line 220 and the rest is bypassed through the control line 230. This will be described later again.
이와 관련하여, 경우에 따라 굴뚝 내 다양한 원인 등에 의해 제2 유량계(510)에 의해 측정되는 총 유량(QTotal)이 입경분리장치(221)에 필요한 정속 유량(예를 들어, 16.67 ℓ/min) 미만일 수 있다. 입경분리장치(221)에 필요한 정속유량조건을 충족하지 못하게 되면 입경분리장치(221)에 의한 입자 분리 및 측정이 사실상 무의미한 동작으로 간주될 수 있으므로, 제2 유량계(510)에 의해 측정되는 총 유량(QTotal)이 입경분리장치(221)에 필요한 정속 유량(예를 들어, 16.67 ℓ/min) 미만으로 하강하는 경우, 본 발명의 추가 실시예에 따르면 컨트롤러(600)는 알람 유닛(미도시)을 활성화함으로써 정속 유량 미만으로의 하강을 사용자 등에게 통지할 수 있거나, 또는 본 굴뚝 배출가스의 미세먼지 연속자동측정장치(10)의 가동을 일시 중지할 수도 있다. 이러한 문제에 대처하기 위해서, 흡인 노즐(111)의 구경을 한 단계 더 크도록, 예를 들어 직경이 12mm인 흡인 노즐(111)로 교체하여 사용할 수도 있다.In this regard, in some cases, the total flow rate (Q Total ) measured by the second flow meter 510 due to various causes within the chimney is a constant flow rate required for the particle size separation device 221 (eg, 16.67 ℓ/min). May be less than. If the constant velocity flow condition required for the particle size separation device 221 is not satisfied, the particle separation and measurement by the particle size separation device 221 may be regarded as a virtually meaningless operation, so the total flow rate measured by the second flow meter 510 When (Q Total ) falls below a constant flow rate (for example, 16.67 ℓ/min) required for the particle size separation device 221, the controller 600 according to a further embodiment of the present invention is an alarm unit (not shown). By activating, it is possible to notify a user or the like of a drop below the constant flow rate, or the operation of the continuous automatic measurement device 10 for fine dust of the present flue gas may be temporarily suspended. In order to cope with this problem, the diameter of the suction nozzle 111 may be increased by one level, for example, a suction nozzle 111 having a diameter of 12 mm may be replaced and used.
가열 장치(140)는 흡인관(110) 외주면의 적어도 일부 영역을 감싸면서 구현될 수 있고, 배출가스 시료의 이송 중 수분의 응축을 방지하기 위해 열 공급원(미도시)으로부터의 열을 흡인관(110) 내의 배출가스 시료에 전달할 수 있다.The heating device 140 may be implemented while surrounding at least a portion of the outer circumferential surface of the suction pipe 110, and to prevent condensation of moisture during the transport of the exhaust gas sample, heat from a heat source (not shown) is absorbed by the suction pipe 110. Can be delivered to the sample of exhaust gas inside.
또한, 흡인관(110)의 길이 방향을 따라 적어도 일부 영역에, 보다 바람직하게는 굴뚝(1)의 내부 영역 및 외부 영역의 경계면 부근에 온도계(130)가 추가로 배치될 수 있으며, 온도계(130)는 흡인관(110)의 온도를 측정하여 다른 엘리먼트에, 예를 들어 컨트롤러(600)에 측정된 온도에 관한 값을 무선으로 또는 유선으로 송신할 수 있다.In addition, a thermometer 130 may be additionally disposed in at least a partial region along the longitudinal direction of the suction pipe 110, more preferably near the boundary between the inner region and the outer region of the chimney 1, and the thermometer 130 May measure the temperature of the suction pipe 110 and transmit the measured temperature value to another element, for example, to the controller 600 wirelessly or by wire.

이와 관련하여, 본 발명의 일 실시예에 따르면, 측정라인(220)에서의 압력 손실 및 제어라인(230)에서의 압력 손실에 기초하여, 분리매니폴드(210)와 제1 제어밸브(231) 사이의 거리가 조절 가능한 것을 특징으로 하는데, 도 4는 본 발명의 일 실시예에 따른 분리매니폴드(210)와 제1 제어밸브(231) 사이의 가변적 거리 조정을 설명하기 위한 개념도에 해당한다. In this regard, according to an embodiment of the present invention, based on the pressure loss in the measurement line 220 and the pressure loss in the control line 230, the separation manifold 210 and the first control valve 231 It is characterized in that the distance between them is adjustable, and FIG. 4 corresponds to a conceptual diagram for explaining the variable distance adjustment between the separation manifold 210 and the first control valve 231 according to an embodiment of the present invention.
본 발명의 일 실시예에 따르면, 측정라인(220)에서의 실제 압력 손실 및/또는 제어라인(230)에서의 실제 압력 손실에 기초하여, 보다 바람직하게는 압력 손실의 차이에 기초하여 분리매니폴드(210)와 제1 제어밸브(231) 사이의 거리가 조절 가능할 수 있는데, 도 4의 (a)는 제1 제어밸브(231)가 분리매니폴드(210)와 결합매니폴드(240)의 대략 중간 영역에 배치되는 구성을 예시적으로 도시하고, 도 4의 (b)는 제1 제어밸브(231)가 분리매니폴드(210) 측에 근접 배치되는 구성을 예시적으로 도시하고, 도 4의 (c)는 제1 제어밸브(231)가 분리매니폴드(210)와 원위 배치되는 구성을 예시적으로 도시한다.According to an embodiment of the present invention, the separation manifold is based on the actual pressure loss in the measurement line 220 and/or the actual pressure loss in the control line 230, more preferably based on the difference in pressure loss. The distance between the 210 and the first control valve 231 may be adjustable, and in (a) of FIG. 4, the first control valve 231 is approximately equal to the separation manifold 210 and the coupling manifold 240.

(c) exemplarily shows a configuration in which the first control valve 231 is disposed distal to the separation manifold 210.
측정라인(220)에서의 압력 손실 및/또는 제어라인(230)에서의 압력 손실에 기초하여 분리매니폴드(210)와 제1 제어밸브(231) 사이의 거리를 가변적으로 조정하는 도 4의 실시예에 추가적으로 또는 대체적으로, 본 발명의 다른 실시예에 따르면 측정라인(220)에서의 압력 손실 및/또는 제어라인(230)에서의 압력 손실에 기초하여 측정라인(220)의 유입부 내경을 제어라인(230)의 유입부 내경과 상이하게 구현할 수도 있고, 또는 내부에 오리피스(orifice)를 설치할 수 있다.Implementation of FIG. 4 in which the distance between the separation manifold 210 and the first control valve 231 is variably adjusted based on the pressure loss in the measurement line 220 and/or the pressure loss in the control line 230 In addition to or alternatively to the example, according to another embodiment of the present invention, the inlet inner diameter of the measurement line 220 is controlled based on the pressure loss in the measurement line 220 and/or the pressure loss in the control line 230.

측정라인(220)은 미세먼지의 분리 및 측정을 위한 라인(또는 경로)으로서, 입경분리장치(221)와, 미세먼지 측정센서(222)와, 제1 유량계(223), 등으로 구성될 수 있다.The measurement line 220 is a line (or path) for separating and measuring fine dust, and may be composed of a particle size separation device 221, a fine dust measurement sensor 222, a first flow meter 223, and the like. have.
입경분리장치(221)는 측정하고자 하는 입자성 물질에 따라 적절하게 선택될 수 있고, 예를 들어 미세먼지를 측정하는 경우 입경분리장치(221)로서 입자의 관성력을 이용하는 임팩터(impactor)와 입자의 원심력을 이용하는 사이클론(cyclone)이 활용될 수 있다. 또한, 측정하고자 하는 입경의 크기에 따라 PM10, PM2.5 등의 선택이 가능하며, 이하의 본 명세서에서는 본 발명의 용이한 이해를 위해서 입경분리장치(221)가 PM10 임팩터(221a) 및 PM2.5 임팩터(221b)로 구성되는 캐스케이드-임팩터로 구현되는 예를 기술하기로 한다. The particle size separation device 221 may be appropriately selected according to the particulate matter to be measured. For example, when measuring fine dust, the particle size separation device 221 uses the inertial force of the particles and A cyclone using centrifugal force can be used. In addition, it is possible to select PM10, PM2.5, etc. according to the size of the particle diameter to be measured, and in the following specification, the particle diameter separation device 221 is a PM10 impactor (221a) and PM2. An example implemented as a cascade-impacter composed of 5 impactors 221b will be described.
참고로, 임팩터는 입자의 관성충돌법칙을 활용하여 유체흐름방향을 급격하게 변화시킬 경우 무거운 입자는 중력과 관성력에 의해 직진성을 갖고 포집관에 출동하여 포집됨에 반해 가벼운 입자는 유체와 함께 진행하는 원리를 이용하므로 유체의 인입 속도, 장치 구조, 치수 설계, 등이 매우 중요하다. For reference, the impactor uses the law of inertial collision of particles to rapidly change the direction of fluid flow, the principle that heavy particles go straight to the collection tube and are collected by gravity and inertial force, whereas light particles proceed with the fluid. Because of the use of the fluid inlet speed, device structure, dimensional design, etc. are very important.
미세먼지 측정센서(222)는 미세먼지를 측정하기 위한 장치로서, 예를 들어 중량법을 위한 필터, 베타레이(Beta-ray) 센서, 광산란 센서 등이 적용될 수 있다. The fine dust measuring sensor 222 is a device for measuring fine dust, and, for example, a filter for a gravimetric method, a beta-ray sensor, a light scattering sensor, and the like may be applied.
제1 유량계(223)는 측정라인(220)에서의 유량을 측정하기 위한 장치로서, 예를 들어 질량유량계(MFM; mass flow meter)를 활용할 수 있다. 참고로, 질량(mass)은 다른 물리량으로부터 측정의 단위가 유도되지 않는 측정의 기준으로서 길이, 시간, 등의 단위와 함께 모든 물리적 측정의 기초를 이루며, 질량유량계는 이러한 불변성의 질량을 측정함으로써 복잡한 계산이 없고 유체 성질에 대한 보정이 없이 직선적이라는 장점이 있다. The first flow meter 223 is a device for measuring the flow rate in the measurement line 220, for example, a mass flow meter (MFM) may be used. For reference, mass is a standard for measurement in which the unit of measurement is not derived from other physical quantities, and forms the basis of all physical measurements along with units such as length, time, etc., and mass flowmeters measure the mass of such an invariant. It has the advantage of being linear without calculation and no correction for fluid properties.
또한, 질량유량계는 유체의 체적(volume) 유량이 아닌 질량(mass) 유량을 측정하는 방식의 유량계로서, 크게 질량 유량에 비례하는 양을 검출하는 방식의 직접형 질량 유량계와, 체적 유량계 및 밀도계를 조합하여 질량 유량을 측정하는 방식의 간접형 질량 유량계로 구분될 수 있다. 예를 들어, 직접형 질량 유량계에는 열식 질량 유량계, 차압식 질량 유량계, 코리올리 질량 유량계, 각운동량식 질량 유량계, 자이로식 질량 유량계, 터빈 질량 유량계, 등이 있다.In addition, the mass flow meter is a flow meter that measures the mass flow rate rather than the volume flow rate of a fluid. A direct mass flow meter, a volume flow meter, and a density meter that detects an amount largely proportional to the mass flow rate. It can be classified as an indirect mass flow meter that measures mass flow by combining it. For example, direct mass flow meters include thermal mass flow meters, differential pressure mass flow meters, Coriolis mass flow meters, angular momentum mass flow meters, gyro mass flow meters, turbine mass flow meters, and the like.
또한, 본 발명의 일 실시예에 따른 질량유량계는 디지털 모드 또는 아날로그 모드로 동작하도록 구현될 수 있고, 디지털 모드와 아날로그 모드 사이에서 동작 모드가 전환될 수 있으며, 그러한 동작 모드의 전환은 컨트롤러(600)에 의해 구현될 수 있다. In addition, the mass flowmeter according to an embodiment of the present invention may be implemented to operate in a digital mode or an analog mode, and an operation mode may be switched between a digital mode and an analog mode, and the switching of such an operation mode is performed by the controller 600 ) Can be implemented by

제어라인(230)은 시료 분기/결합부(200)에 구비되는 복수의 라인에서 측정라인(220)을 제외한 나머지 라인에 해당하며, 도 2에서는 제어라인(230)으로서 하나의 라인을 예시적으로 도시하고 있지만 본 발명의 추가 실시예에 따르면 제어라인(230)이 복수의 라인(예를 들어, 2개 라인, 3개 라인, 등)으로 구현될 수도 있다.The control line 230 corresponds to the remaining lines excluding the measurement line 220 from the plurality of lines provided in the sample branch/combination unit 200, and in FIG. 2, one line is illustratively used as the control line 230. Although shown, according to a further embodiment of the present invention, the control line 230 may be implemented as a plurality of lines (eg, two lines, three lines, etc.).
제어라인(230)에는 제1 제어밸브(231)가 구비될 수 있고, 상기 제1 제어밸브(231)와 분리매니폴드(210) 사이의 거리가 측정라인(220)에서의 압력 손실 및/또는 제어라인(230)에서의 압력 손실에 기초하여 가변적으로 조정 가능하다는 것은 이미 기술한 바와 같다. 또한, 제어라인(230)에 구비되는 제1 제어밸브(231)의 개폐를 조절함으로써 측정라인(220)에 구비된 입경분리장치(221)의 정속유량조건을 충족시킬 수 있으며, 제1 제어밸브(231)의 개폐 조절 제어는 컨트롤러(600)로부터 출력되는 제어 신호(i231)에 의해 가능할 수 있다. The control line 230 may be provided with a first control valve 231, and the distance between the first control valve 231 and the separation manifold 210 is a pressure loss in the measurement line 220 and/or It is already described that it is variably adjustable based on the pressure loss in the control line 230. In addition, by controlling the opening and closing of the first control valve 231 provided in the control line 230, the constant speed flow rate condition of the particle size separation device 221 provided in the measurement line 220 can be satisfied, and the first control valve The opening and closing control control of the 231 may be possible by a control signal i 231 output from the controller 600.
도 3은 본 발명의 일 실시예에 따른 제1 제어밸브(231)의 개폐 동작에 의해 측정라인(220)의 정속 유량을 구현하는 실시예를 설명하기 위한 개념도이다. 입경분리장치(221)가 캐스케이드-임팩터인 경우에 입경분리장치(221)에 필요한 정속 유량은 16.67 ℓ/min이고 미세먼지의 정확한 검출 및 측정을 위해서는 입경분리장치(221)에서의 정속 유량 조건(16.67 ℓ/min)이 반드시 준수되어야만 한다.3 is a conceptual diagram for explaining an embodiment of implementing a constant flow rate of the measurement line 220 by the opening and closing operation of the first control valve 231 according to an embodiment of the present invention. When the particle size separation device 221 is a cascade-impacter, the constant flow rate required for the particle size separation device 221 is 16.67 ℓ/min, and for accurate detection and measurement of fine dust, the constant flow rate condition in the particle size separation device 221 ( 16.67 ℓ/min) must be observed.
도 3의 (a)에 예시되는 바와 같이, 등속흡인제어부(500)에 구비된 제2 유량계(510)에 의해서 합산 유량(QTotal)이 20 ℓ/min로 측정되고, 측정라인(220)에 구비된 제1 유량계(223)에 의해서 입경분리장치(221)의 유량이 15 ℓ/min로 측정되는 경우에, 컨트롤러(60)는 제어라인(230)에 5 ℓ/min의 유량이 있다고 판단할 수 있다.As illustrated in (a) of FIG. 3, the summation flow rate (Q Total ) is measured at 20 ℓ/min by the second flow meter 510 provided in the constant velocity suction control unit 500, and the measurement line 220 When the flow rate of the particle size separation device 221 is measured as 15 L/min by the provided first flow meter 223, the controller 60 determines that there is a flow rate of 5 L/min in the control line 230. I can.
따라서, 캐스케이드-임팩터로 구현되는 입경분리장치(221)에 16.67 ℓ/min의 정속유량조건을 충족시키기 위해서, 컨트롤러(600)는 제어라인(230)의 5 ℓ/min 유량에서 1.67 ℓ/min를 감소시키고 측정라인(220)의 15 ℓ/min 유량에서 1.67 ℓ/min를 증가시키기 위해서 제1 제어밸브(231)를 더 폐쇄하도록 제어할 수 있다.Therefore, in order to meet the constant flow rate condition of 16.67 L/min in the particle size separation device 221 implemented as a cascade-impacter, the controller 600 controls 1.67 L/min at the 5 L/min flow rate of the control line 230. In order to decrease and increase 1.67 L/min at the 15 L/min flow rate of the measurement line 220, the first control valve 231 may be further closed.
유사하게, 도 3의 (b)에 예시되는 바와 같이, 등속흡인제어부(500)에 구비된 제2 유량계(510)에 의해서 합산 유량(QTotal)이 20 ℓ/min로 측정되고, 측정라인(220)에 구비된 제1 유량계(223)에 의해서 입경분리장치(221)의 유량이 18 ℓ/min로 측정되는 경우에, 컨트롤러(60)는 제어라인(230)에 2 ℓ/min의 유량이 있다고 판단할 수 있다.Similarly, as illustrated in (b) of FIG. 3, the summation flow rate (Q Total ) is measured as 20 ℓ/min by the second flow meter 510 provided in the constant velocity suction control unit 500, and the measurement line ( When the flow rate of the particle size separation device 221 is measured as 18 L/min by the first flow meter 223 provided in 220), the controller 60 has a flow rate of 2 L/min in the control line 230 You can judge that there is.
따라서, 캐스케이드-임팩터로 구현되는 입경분리장치(221)에 16.67 ℓ/min의 정속유량조건을 충족시키기 위해서, 컨트롤러(600)는 제어라인(230)의 2 ℓ/min 유량에서 1.33 ℓ/min를 증가시키고 측정라인(220)의 18 ℓ/min 유량에서 1.33 ℓ/min를 감소시키기 위해서 제1 제어밸브(231)를 더 개방하도록 제어할 수 있다.Therefore, in order to meet the constant flow rate condition of 16.67 L/min in the particle size separation device 221 implemented as a cascade-impacter, the controller 600 controls 1.33 L/min at the 2 L/min flow rate of the control line 230. In order to increase and decrease 1.33 L/min at the flow rate of 18 L/min of the measurement line 220, the first control valve 231 may be controlled to be further opened.
정리하면, 본 발명의 일 실시예에 따른 컨트롤러(600)는 제1 유량계(223) 및 제2 유량계(510)에 의해서 측정되는 유량(즉, Q220, QTotal)에 기초하여 제1 유량계(223)에 의해 측정되는 유량이 입경분리장치(221)에 필요한 정속 유량(예를 들어, 16.67 ℓ/min)에 대응하도록 제1 제어밸브(231)의 개폐를 제어할 수 있다. In summary, the controller 600 according to an embodiment of the present invention is based on the flow rate measured by the first flow meter 223 and the second flow meter 510 (ie, Q 220 , Q Total ), the first flow meter ( Opening and closing of the first control valve 231 may be controlled so that the flow rate measured by 223 corresponds to a constant speed flow rate (eg, 16.67 L/min) required for the particle size separation device 221.
보다 구체적으로, 컨트롤러(600)는 제1 유량계(223)에 의해 측정되는 유량이 입경분리장치(221)에 필요한 정속 유량을 초과하는 경우 제1 제어밸브(231)를 개방하고, 그리고 제1 유량계(223)에 의해 측정되는 유량이 입경분리장치(221)에 필요한 정속 유량 미만인 경우 제1 제어밸브(231)를 폐쇄하도록 구성될 수 있다.More specifically, the controller 600 opens the first control valve 231 when the flow rate measured by the first flow meter 223 exceeds the constant speed flow rate required for the particle size separation device 221, and the first flow meter When the flow rate measured by 223 is less than the constant speed flow rate required for the particle size separation device 221, the first control valve 231 may be closed.
참고로, 상기한 바와 같은 복수의 라인의 유량 분기 및 조정을 수행함에 있어서, 측정라인(220) 및/또는 제어라인(230)의 압력 손실을 추가로 고려하는 것 또한 중요하며, 예를 들어 측정라인(220)에서의 압력 손실 및/또는 제어라인(230)에서의 압력 손실에 기초하여 분리매니폴드(210)와 제1 제어밸브(231) 사이의 거리를 가변적으로 조정 가능한 구성은 이미 설명한 바와 같다.For reference, in performing the flow rate branching and adjustment of a plurality of lines as described above, it is also important to additionally consider the pressure loss of the measurement line 220 and/or the control line 230, for example, measurement The configuration in which the distance between the separation manifold 210 and the first control valve 231 can be variably adjusted based on the pressure loss in the line 220 and/or the pressure loss in the control line 230 has already been described. same.
결합매니폴드(240)는 측정라인(220) 및 제어라인(230)으로부터의 시료 유량을 결합하여 후단의 전처리부(300), 가스측정부(400), 등속흡인제어부(500) 등으로 전달하도록 구성될 수 있다.The coupling manifold 240 combines the sample flow rate from the measurement line 220 and the control line 230 and transmits it to the pretreatment unit 300, the gas measurement unit 400, the constant velocity suction control unit 500, etc. Can be configured.
전처리부(300)는 냉각기(310)와 배출펌프(320)로 구성될 수 있다. 전처리부(300)는 가스측정부(400) 및/또는 등속흡인제어부(500)에서의 정상적인 측정 및/또는 제어 동작을 위한 전처리를 수행할 수 있으며, 예를 들어 전처리부(300)는 수분 제거를 구현할 수 있다.The pretreatment unit 300 may be composed of a cooler 310 and a discharge pump 320. The pretreatment unit 300 may perform pretreatment for normal measurement and/or control operation in the gas measurement unit 400 and/or the constant velocity suction control unit 500. For example, the pretreatment unit 300 removes moisture Can be implemented.
예를 들어, 가스측정부(400)에서 배출가스 성분을 측정하기 위해서 가스 센서를 사용하는데, 일반적으로 가스 센서는 수분에 매우 큰 영향을 받는다. 따라서, 수분에 의한 가스 센서의 측정 오차 및 고장을 감소시키기 위해서 전처리부(300)는 결합매니폴드(240)를 통해 출력되는 배출가스의 수분을 제거할 수 있다. 수분이 다수 함유된 배출가스가 냉각기(310)를 통과하면 수분이 응축되면서 물로 변환되고, 변환된 물은 배출펌프(320)를 통해 외부로 배출됨으로써 배출가스로부터 수분이 제거될 수 있다. For example, a gas sensor is used to measure an exhaust gas component in the gas measurement unit 400, and in general, the gas sensor is greatly affected by moisture. Accordingly, in order to reduce measurement errors and failures of the gas sensor due to moisture, the pretreatment unit 300 may remove moisture from the exhaust gas output through the coupling manifold 240. When the exhaust gas containing a large number of moisture passes through the cooler 310, moisture is condensed and converted into water, and the converted water is discharged to the outside through the discharge pump 320, thereby removing moisture from the exhaust gas.
가스측정부(400)는 다양한 종류의 가스 센서를 구비할 수 있으며, 본 명세서에서는 등속 흡인 유량의 계산과 관련하여 공기 밀도 보정을 위해 산소 센서(410)와 이산화탄소 센서(420)를 예시적으로 기술하기로 한다. 산소 센서(410)의 경우 배출가스 내의 산소를 측정하기 위한 장치에 해당하고, 이산화탄소 센서(420)의 경우 배출가스 내의 이산화탄소를 측정하기 위한 장치에 해당한다. 참고로, 가스측정부(400)의 전단에서 전처리부(300)에 의해서 수분 제거가 수행되므로, 산소 센서(410), 이산화탄소 센서(420) 등의 센서는 대상 가스의 수분이 제거될지라도 제거 이전과 측정 오차가 발생하지 않는 가스의 특성에 부합하는 센서 장치로서 구현될 수 있다. The gas measurement unit 400 may include various types of gas sensors, and in this specification, the oxygen sensor 410 and the carbon dioxide sensor 420 are exemplarily described to correct air density in relation to the calculation of the constant velocity suction flow rate. I will do it. The oxygen sensor 410 corresponds to a device for measuring oxygen in the exhaust gas, and the carbon dioxide sensor 420 corresponds to a device for measuring carbon dioxide in the exhaust gas. For reference, since moisture is removed by the pretreatment unit 300 at the front end of the gas measurement unit 400, sensors such as the oxygen sensor 410 and the carbon dioxide sensor 420 may be removed even if the moisture of the target gas is removed. It can be implemented as a sensor device that conforms to the characteristics of a gas that does not cause overmeasurement errors.
등속흡인제어부(500)는 시료 채취부(100)에서의 등속유량조건을 충족시키기 위해서 제2 제어밸브(520) 및/또는 흡인펌프(530)의 동작을 제어할 수 있다. 예를 들어, 등속흡인제어부(500)에 구비된 제2 유량계(510)에 의해 측정되는 유량(QTotal)에 기초하여, 등속흡인제어부(500)에 구비된 흡인펌프(530)가 일정한 파워를 출력하면서 제2 제어밸브(520)의 개폐를 제어함으로써, 또는 등속흡인제어부(500)에 구비된 흡인펌프(530) 자체의 파워를 조절함으로써(이 경우, 제2 제어밸브(520)는 생략될 수 있음) 시료 채취부(100)에서의 등속 유량 채취를 구현할 수 있다. 추가로, 본 발명의 추가 실시예에 따르면, 시료 채취부(100)에서의 등속 유량을 구현하기 위해서, 등속흡인제어부(500)에 구비된 제2 유량계(510)에 의해 측정되는 유량(QTotal)에 기초하여 제2 제어밸브(520)의 개폐를 조절하는 동시에 펌프의 압력을 조절하는 방식을 활용할 수도 있다. The constant velocity suction control unit 500 may control the operation of the second control valve 520 and/or the suction pump 530 in order to satisfy the constant velocity flow rate condition in the sample collection unit 100. For example, based on the flow rate (Q Total ) measured by the second flow meter 510 provided in the constant velocity suction control unit 500, the suction pump 530 provided in the constant velocity suction control unit 500 generates a constant power. By controlling the opening and closing of the second control valve 520 while outputting, or by adjusting the power of the suction pump 530 itself provided in the constant velocity suction control unit 500 (in this case, the second control valve 520 will be omitted. May) It is possible to implement a constant velocity flow rate collection in the sample collection unit 100. In addition, according to a further embodiment of the present invention, in order to implement the constant velocity flow rate in the sample collection unit 100, the flow rate measured by the second flow meter 510 provided in the constant velocity suction control unit 500 (Q Total ) Based on the method of controlling the opening and closing of the second control valve 520 and simultaneously controlling the pressure of the pump.
여기서, 제2 유량계(510)는 질량유량계일 수 있고, 또는 전처리부(300)에서 가스의 수분이 제거되므로 상대적으로 가격이 저렴한 건식유량계가 대체적으로 활용될 수도 있다.Here, the second flow meter 510 may be a mass flow meter, or a dry flow meter, which is relatively inexpensive, may be used in general since moisture from the gas is removed from the pretreatment unit 300.
