Description

석탄가스화 복합발전소의 유해가스 감시 및 안전 관리 시스템{HARMFUL GASES MONITORING AND SAFETY MANAGEMENT SYSTEM FOR INTEGRATED GASIFICATION COMBINED CYCLE POWER PLANT}HARMFUL GASES MONITORING AND SAFETY MANAGEMENT SYSTEM FOR INTEGRATED GASIFICATION COMBINED CYCLE POWER PLANT}

본 발명은 석탄가스화 복합발전소의 유해가스 감시 및 안전 관리 시스템에 관한 것이다. 보다 구체적으로, 본 발명은 많은 유해가스들이 발생하고 고온/고압에 노출되어 있는 석탄가스화 복합발전소에서 발생할 수 있는 위험상황에 즉각적이고 효율적으로 대처할 수 있도록 하는 석탄가스화 복합발전소의 유해가스 감시 및 안전 관리 시스템에 관한 것이다.The present invention relates to a harmful gas monitoring and safety management system of a coal gasification combined cycle power plant. More specifically, the present invention provides a hazardous gas monitoring and safety management of a coal gasification combined cycle power plant that can promptly and efficiently cope with a dangerous situation that may occur in a coal gasification combined cycle power plant is exposed to a high temperature / high pressure and a lot of harmful gases are generated. It is about the system.

석탄가스화 복합발전소는 고온/고압 하에서 석탄을 산소 및 수증기와 반응시켜 합성가스(CO+H2)를 생산하고, 이를 가스터빈과 증기터빈으로 구동하는 복합 발전시스템으로서, 가스화 과정 중에서 탄소(C)의 일부분만이 완전 연소하여 이산화탄소(CO2)로 전환되며, 이때 발생된 열에너지는 석탄 중의 화학결합을 해리하고, 생성물의 온도를 높이며, 흡열반응에 필요한 에너지를 제공하고 있다.The coal gasification combined cycle power plant is a complex power generation system that reacts coal with oxygen and steam at high temperature / high pressure to produce syngas (CO + H 2 ) and drives it with gas turbines and steam turbines. Only part of is completely burned and converted into carbon dioxide (CO 2 ), where the heat energy dissociates the chemical bonds in coal, increases the temperature of the product, and provides the energy necessary for the endothermic reaction.

이 과정에서 온도가 상승함에 따라 휘발화가 일어나서 약한 화학결합들이 해리되어 타르, 오일, 페놀 및 탄화수소 가스가 생성되고, 휘발화 과정 이후에 남은 고정탄소는 산소(O2), 증기(H2O), 이산화탄소(CO2) 및 수소(H2)와 반응하여 가스화 되고, 가스들은 상호간에 반응하여 가스 혼합물을 생성하여 인체에 접촉했을 매우 위험하다.As the temperature rises in this process, volatilization occurs and weak chemical bonds dissociate to produce tar, oil, phenol, and hydrocarbon gas, and the fixed carbon remaining after volatilization is oxygen (O 2 ), steam (H 2 O). , Gasification by reacting with carbon dioxide (CO 2 ) and hydrogen (H 2 ), the gases react with each other to form a gas mixture is very dangerous to contact the human body.

위와 같이 석탄가스화 복합발전소에서는 많은 유해가스들이 발생하고 고온/고압에 노출되어 있어 작업자들에게 위험하고 피해를 초래할 수가 있는 위험 시설이라 할 수 있다.As described above, in the coal gasification combined cycle power plant, many harmful gases are generated and exposed to high temperature / high pressure, which is dangerous and can cause damage to workers.

이러한 위험에 대처하기 위하여, 국내에는 일부 거치식 온도센서 등을 장착하여 오프라인으로 유해가스 감지를 시도하고 있으나 유해가스 누출에 대한 모니터링은 정밀도가 매우 낮다는 문제점이 있다.In order to cope with such a risk, in Korea, some stationary temperature sensors are installed to try to detect harmful gases off-line, but there is a problem that the monitoring of harmful gas leakage is very low accuracy.

석탄가스화 복합발전소의 위험 상황에 대처하기 위하여, 해외에서는, 고가의 광학식 센서를 사용하여 온도를 모니터링하고, 내구성 있는 고압 센서를 사용하여 압력을 모니터링하고 있으나, IoT와 연계한 실시간 대처 기술은 미흡하기 때문에, 석탄가스화 복합발전소의 위험상황에 효과적으로 대처할 수 없다는 문제점이 있다.In order to cope with the dangerous situation of the coal gasification combined cycle power plant, overseas countries monitor the temperature using expensive optical sensors and the pressure using durable high pressure sensors, but the real-time response technology associated with IoT is insufficient. However, there is a problem in that it cannot effectively cope with the dangerous situation of a coal gasification combined cycle power plant.

도 1을 참조하면, 본 발명의 일 실시 예에 따른 석탄가스화 복합발전소의 유해가스 감시 및 안전 관리 시스템은 감지부 및 통합 관리부를 포함한다.Referring to FIG. 1, a noxious gas monitoring and safety management system of a coal gasification combined cycle power plant according to an embodiment of the present invention includes a detection unit and an integrated management unit.

감지부(10)는 석탄가스화 복합발전소의 지정된 위치에 설치되어 있으며, 석탄가스화 복합발전소에서 발생하는 일산화탄소(CO), 수소(H2), 이산화탄소(CO2), 산소(O2), 수증기(H2O), 유해물질 타르(벤츠 a 피렌), 페놀을 온도(T), 압력(P)과 연계하여 감지하고, 감지 데이터를 통합 관리부로 실시간 전송하는 기능을 수행한다.The detector 10 is installed at a designated location of the coal gasification combined cycle power plant, and generates carbon monoxide (CO), hydrogen (H 2 ), carbon dioxide (CO 2 ), oxygen (O 2 ), and water vapor ( H 2 O), harmful substances tar (benz a pyrene), phenol is detected in connection with the temperature (T), pressure (P), and transmits the detection data to the integrated management in real time.

예를 들어, 감지부(10)는 일산화탄소 감지부(110), 수소 감지부(120), 이산화탄소 감지부(130), 산소 감지부(140), 수증기 감지부(150), 유해물질 타르 감지부(160), 페놀 감지부(170), 온도 감지부(180) 및 압력 감지부(190)를 포함하여 구성될 수 있으나, 감지부(10)의 구성이 이에 한정되지는 않는다.For example, the detector 10 includes a carbon monoxide detector 110, a hydrogen detector 120, a carbon dioxide detector 130, an oxygen detector 140, a water vapor detector 150, and a hazardous substance tar detector. 160, the phenol sensing unit 170, the temperature sensing unit 180, and the pressure sensing unit 190 may be configured, but the configuration of the sensing unit 10 is not limited thereto.

통합 관리부(20)는 감지부(10)로부터 잔달받은 감지 데이터에 기계학습 알고리즘을 적용하여 석탄가스화 복합발전소의 현재 상황을 판단하고, 판단 결과를 외부로 전파하는 기능을 수행한다.The integrated management unit 20 performs a function of determining the current situation of the coal gasification combined cycle power plant by applying a machine learning algorithm to the sensed data received from the detection unit 10 and propagating the determination result to the outside.

발명의 배경이 되는 기술에 대한 설명 부분에서 설명한 바 있지만, 석탄가스화 복합발전소에서는 많은 유해가스들이 발생하고 고온/고압에 노출되어 있어 작업자들에게 위험하고 피해를 초래할 수가 있다.Although described in the description of the technology that is the background of the invention, in the coal gasification combined cycle power plant many harmful gases are generated and exposed to high temperature / high pressure can be dangerous and damage to workers.

본 발명의 일 실시 예는 이러한 문제를 해결하기 위한 도출된 것으로서, 본 발명의 일 실시 예는 4차 산업과 연계하여 유해가스 센서 모듈에 무선통신 기능을 탑재하여 사물인터넷(IoT)으로 연결하여 실시간 감시하고, 위험시 경보, 화재안전 및 차단조치를 취하고, 관리자의 스마트기기로 알려주어 사후 조치를 취하게 하는 효율적인 안전관리시스템에 관한 기술이다.One embodiment of the present invention is derived to solve such a problem, an embodiment of the present invention is connected to the 4th industry in real time by connecting to the Internet of Things (IoT) equipped with a wireless communication function in the harmful gas sensor module It is an efficient safety management system that monitors, takes alarm, fire safety and blocking measures in case of danger, and informs the administrator's smart device to take follow-up measures.

종래 기술은 석탄가스화 발전소에서 발생하는 일산화탄소(CO) 및 수소(H2) 등 주요 가스나 유해 물질만 감시하거나 온도측정은 단순 지시계를 이용하여 데이터를 확인하는 단순한 수준의 기술이었기 때문에, 석탄가스화 복합발전소의 위험 상황에 적절하게 대처할 수 없었다.Since the prior art is a simple technology that monitors only major gases or harmful substances such as carbon monoxide (CO) and hydrogen (H 2 ) generated from coal gasification power plants, or measures temperature using a simple indicator, the coal gasification complex It was not possible to adequately cope with the hazardous situation of the power plant.

반면, 본 발명은 석탄가스화 발전소에서 발생하는 일산화탄소(CO), 수소(H2), 이산화탄소(CO2), 산소(O2), 온도(T), 고압(P) 및 수증기(H2O)와 유해물질 타르(벤츠 a 피렌)와 페놀 감지기를 설치하고 무선통신 모듈을 장착하고, 사물인터넷으로 연결하여 실시간 빅데이터(Big Data)를 수집하여 위험상황을 인지하는 알고리즘을 통하여 위험과 안전상황을 알려주고, 위험시 의사를 결정을 통해 경보, 화재안전 및 차단조치를 취할 수 있는 통합안전관리 시스템을 구축하는 기술이기 때문에, 석탄가스화 복합발전소에서 발생할 수 있는 위험상황에 즉각적이고 효율적으로 대처할 수 있다.On the other hand, the present invention is carbon monoxide (CO), hydrogen (H 2 ), carbon dioxide (CO 2 ), oxygen (O 2 ), temperature (T), high pressure (P) and water vapor (H 2 O) generated in coal gasification power plant And hazardous materials tar (benz a pyrene) and phenol detectors are installed, wireless communication modules are installed, and real-time big data is collected by connecting to the Internet of Things to identify risks and safety situations through algorithms. It is a technology that establishes an integrated safety management system that informs and makes decisions in case of danger and takes alarm, fire safety and blocking measures, so that it can respond immediately and efficiently to the risks that may occur in the coal gasification combined cycle power plant.

즉, 석탄가스화 발전소는 유해가스 누출이나 고온/고압의 위험이 항시 존재하는 위험 시설인데, 본 발명에 따르면, 이러한 위험요소를 실시간 상시 모니터링 할 수 있으며, 무선통신을 통하여 원격에서 관리할 수 있으므로 화력발전소는 물론, 복합화력발전소 및 원자력 발전소에도 상시 모니터링 시스템을 구축 및 활용할 수 있으며, 발전소 사고예방을 강화할 수 있다.In other words, coal gasification power plant is a hazardous facility that is always in danger of harmful gas leakage or high temperature / high pressure, according to the present invention, it is possible to monitor these risks in real time at all times, and can be managed remotely through wireless communication In addition to power plants, combined-cycle power plants and nuclear power plants can be built and used at all times to monitor and enhance plant accident prevention.
