Description
본 발명은 일정농도유지가 가능한 디젤차량용 요소수 정량화 생산시스템에 관한 것으로, 더욱 상세하게는 요소수의 용해과정에서 정확한 원료의 양을 기존방식의 수동식에서 자동화 형태의 무게감지장치를 활용하여 품질인증규격에 맞는 제품을 생산하고 생산공정을 효율화하여 나아가서는 제품경쟁력을 확보하고, 정확한 품질을 유지하여 디젤자동차의 요소수 인젝터나 SCR 촉매의 막힘 등으로 인해 SCR 내부는 물론 배기머플러 등에 쌓여 배압을 형성, 엔진 출력 및 연비를 떨어트리는 부작용이 발생을 방지하기 위한 일정농도유지가 가능한 디젤차량용 요소수 정량화 생산시스템에 관한 것이다. The present invention relates to a production system for quantifying urea water for diesel vehicles capable of maintaining a certain concentration, and more particularly, quality certification by using an automated weight sensing device in a conventional manual method to determine the exact amount of raw materials in the process of dissolving urea water. Produces products that meet the standard and improves the production process, thereby securing product competitiveness and maintaining accurate quality to form back pressure by accumulating inside the SCR as well as the exhaust muffler due to clogging of the urea water injector or SCR catalyst of a diesel vehicle. , It relates to a production system for quantifying the number of urea for diesel vehicles capable of maintaining a certain concentration to prevent the occurrence of side effects that reduce engine power and fuel economy.
요소수(尿素水, Urea)는 액상의 화학물질로서 우리가 흔히 알고 있는 요소비료의 원료인 요소(Urea)와 순수한 물(Water)을 혼합하여 만든 농도 31.8~33.2%의 화학물질이다. 이 요소수가 디젤엔진 자동차의 질소산화물을 정화하는데 쓰인다. 질소산화물은 기관지염, 폐렴 등 각종 호흡기질환을 일으키며 광학 스모그와 산성비의 주요 원인으로 알려져 있다. 연구 결과 교통사고 사망자의 2배가 넘는 사람이 자동차 매연으로 숨지고 있다는 보고가 있을 정도로 우리 일상생활에 차량배기가스가 미치는 영향이 크다. 그래서 선진국을 중심으로 오래전부터 꾸준히 제기되어 온 온실가스감축의 일환으로 차량배기가스 규제가 점점 엄격해지고 있는 것이다. 우리나라는 '경유자동차배기가스규제'로 유럽기준을 따르고 있다.Urea water (urea) is a liquid chemical substance with a concentration of 31.8 to 33.2% made by mixing urea and pure water, which are commonly known raw materials for urea fertilizer. This urea water is used to purify nitrogen oxides in diesel engine vehicles. Nitrogen oxide causes various respiratory diseases such as bronchitis and pneumonia, and is known to be the main cause of optical smog and acid rain. As a result of the study, there are reports that more than twice the number of deaths in traffic accidents are dying from automobile smoke, so the effect of vehicle exhaust on our daily lives is great. That is why vehicle exhaust regulations are becoming more and more stringent as a part of greenhouse gas reduction, which has been steadily raised since long ago, mainly in developed countries. Korea is following the European standard for'diesel vehicle exhaust gas regulation'.
자동차분야에서의 SCR 촉매 시스템은 환원제로서 암모니아를 사용함으로써 DeNOx 성능을 90% 이상 달성 가능하나 암모니아는 가스상이기 때문에 보관이 어렵고 누수로 인해 인체에 악영향을 미치는 단점이 있어 사용이 거의 불가능하다. 이러한 암모니아를 촉매를 사용하는 SCR 시스템의 단점을 보완할 수 있는 방식이 Urea-SCR 시스템이다.The SCR catalyst system in the automotive field can achieve more than 90% of DeNOx performance by using ammonia as a reducing agent, but it is difficult to store because ammonia is gaseous, and it is almost impossible to use because it has a disadvantage that adversely affects the human body due to leakage. The Urea-SCR system is a method that can compensate for the shortcomings of the SCR system using ammonia catalyst.
요소수를 사용하여 질소산화물을 정화하는 기술을 Urea-SCR이라 하며, 미국에서는 DEF(Diesel Exhaust Fluid), 유럽에서는 AdBlue로 칭한다. 요소수는 온도에 따라 어는점의 변화가 매우 크다. 농도가 32.5%일 때 빙점이 -11℃로써 가장 낮기 때문에 표준을 정할 때 자동차용 요소의 농도를 32.5%로 정하고 있고, 이외에 선박용 40%, 산업용 40%로 요소의 농도를 정하고 있다.The technology to purify nitrogen oxides using urea water is called Urea-SCR, in the US it is called as DEF (Diesel Exhaust Fluid) and in Europe as AdBlue. Urea water has a very large change in freezing point with temperature. When the concentration is 32.5%, the freezing point is -11℃, which is the lowest, so when setting the standard, the concentration of urea for automobiles is set at 32.5%, and the concentration of urea is set at 40% for ships and 40% for industrial use.
Urea-SCR 시스템의 자동차는 엔진이 가동되고 있으면 요소수가 지속적으로 사용되며, 이때 사용되는 양은 연료대비 4~6%정도 소모된다. 강화된 배기가스배출규제에 대응하기 위한 시스템에서 SCR은 EGR+DPF시스템보다 연비가 평균 3~5%의 개선효과가 있다는 연구결과가 있다. 그러므로 요소수의 사용으로 추가적인 비용이 들지만 연비 효과로 인하여 전체적인 운행경비는 Urea-SCR이 경제적이라 하겠다.Urea-SCR system vehicles use urea water continuously when the engine is running, and the amount used at this time is consumed about 4-6% of the fuel. In a system to cope with the reinforced exhaust gas emission regulations, there is a research result that SCR has an average of 3~5% improvement in fuel efficiency than the EGR+DPF system. Therefore, the use of urea water incurs additional costs, but due to the fuel economy effect, the overall operating cost of Urea-SCR is economical.
Urea-SCR 시스템은 디젤엔진에서 발생한 배기가스가 SCR 촉매장치를 거치는 과정에서 요소수 주입장치를 통해 요소수를 주입함으로써 배기가스 내의 질소산화물을 정화하게 된다.The Urea-SCR system purifies nitrogen oxides in the exhaust gas by injecting urea water through the urea water injection device while the exhaust gas generated from the diesel engine passes through the SCR catalyst.
이와 같이 Urea-SCR 시스템에 사용되는 요소수를 제조함에 있어, 요소수 제조사는 요소수 공급 장치를 통해 유통되는 요소수 제품의 품질 관리에 많은 어려움을 겪고 있어 요소수의 농도가 업체마다 차이가 많고, 이로 인한 판매되고 있는 요소수의 실질적 성능 또한 차이가 있으며, 이러한 차이는 곧 자동차의 인젝터나 SCR 촉매에 영향을 주게 되어 엔진출력이나 연비를 떨어뜨리는 요인이 되고 있다.In manufacturing the urea water used in the Urea-SCR system as described above, the urea water manufacturer has a lot of difficulty in quality control of the urea water products distributed through the urea water supply device, so the concentration of urea water varies greatly from company to company. As a result, there is also a difference in the actual performance of the number of urea sold, and this difference soon affects the injector or SCR catalyst of the vehicle, which is a factor that lowers engine power or fuel economy.
더욱이, 품질인증규격에 적합한 요소수를 생산한다라고 하더라도 제조사마다 상이한 농도와 품질과 외부의 높은 온도에 장시간 노출되거나 기타 환경 조건으로 인한 수분증발 등의 요인으로 인해 실제 요소수의 농도가 자동차로 공급되기 위한 기준 농도를 유지하지 못하는 문제가 있고, 이로 인한 요소수의 농도변화로 인해 요소수의 농도가 낮을 경우에는 자동차 배기가스의 질소산화물의 정화력이 떨어져 대기환경오염원의 제거능력이 떨어지는 문제가 있는 한 편, 요소소의 농도가 높아지면 요소수가 결정화되거나 끈적이는 점성을 가지게 되어 자동차의 요소수 인젝터나 SCR 촉매의 막힘 또는 촉매 깨짐현상이 발생하거나 산화환원(화학반응) 과정에서 발생하는 요소수 고분자물질(멜라닌 등), 금속염 등으로 인해 SCR 내부는 물론 배기머플러 등에 쌓여 배압을 형성, 엔진 출력 및 연비를 떨어트리는 부작용이 발생되는 문제가 있었다. Moreover, even if urea water is produced that meets the quality certification standards, the actual concentration of urea water is supplied to automobiles due to factors such as different concentrations and quality, exposure to high external temperatures for a long time, or moisture evaporation due to other environmental conditions. There is a problem of not maintaining the standard concentration to be used, and if the concentration of urea water is low due to the change in the concentration of urea water, there is a problem that the purifying power of nitrogen oxides in automobile exhaust gas decreases and the ability to remove air pollutants decreases. On the other hand, when the concentration of urea increases, urea water crystallizes or has a sticky viscosity, causing clogging of the urea water injector or SCR catalyst in automobiles, or catalyst cracking, or urea water polymer substances generated in the process of redox (chemical reaction). Melanin, etc.), metal salts, etc., accumulates inside the SCR as well as the exhaust muffler to form back pressure, causing side effects of lowering engine output and fuel economy.
따라서, 본 발명은 상술한 바와 같은 문제점을 해결하기 위해 창출한 것으로, 제조사마다 다른 요소수의 농도를 일정한 농도로 유지하도록 함으로써, 자동차에 양질의 요소수를 공급함에 따라 불순물로 인해 발생되는 차량의 요소수 인젝터나 SCR 촉매의 막힘 또는 촉매 깨짐현상이 발생을 방지하고, 산화환원 과정에서 발생하는 요소수 고분자물질인 멜라니, 금속염 등이 SCR 내부는 물론 배기머플러 등에 쌓여 배압을 형성, 엔진 출력 및 연비를 떨어트리는 부작용 발생을 방지할 수 있는 일정농도유지가 가능한 디젤차량용 요소수 정량화 생산시스템을 제공하는 데 그 목적이 있다. Therefore, the present invention was created to solve the above-described problem, and by maintaining the concentration of urea water different from manufacturer to manufacturer at a constant concentration, Prevents the occurrence of urea water injector or SCR catalyst clogging or catalyst cracking, and urea water polymeric substances such as melanie and metal salts generated during the redox process accumulate inside the SCR as well as the exhaust muffler to form back pressure, engine output and fuel economy Its purpose is to provide a production system for quantifying urea water for diesel vehicles capable of maintaining a certain concentration that can prevent the occurrence of side effects such as dropping.
또한, 본 발명은 제조사마다 서로 다른 농도로 제조된 요소수의 농도를 일정하게 유지하도록 하여 SCR 촉매나 요소수 인젝터 노즐이 막히는 등 각종 부작용 발생방지 및 배출가스 정화능력 저하를 방지할 수 있는 일정농도유지가 가능한 디젤차량용 요소수 정량화 생산시스템을 제공하는 데 또 다른 목적이 있다. In addition, the present invention maintains a constant concentration of urea water produced at different concentrations for each manufacturer, thereby preventing the occurrence of various side effects such as clogging of the SCR catalyst or the urea water injector nozzle, and a certain concentration that can prevent the reduction of exhaust gas purification ability. Another object is to provide a system for quantifying urea water for diesel vehicles that can be maintained.
본 발명에 따른 일정농도유지가 가능한 디젤차량용 요소수 정량화 생산시스템은 순수장치-순수저장탱크-다이아프램펌프-펌프/솔레노이드제어를 통한 원료공급부와; 원료공급부를 통해 공급된 요소수의 질량을 감지하는 질량감지로드셀유닛과; 밀도대비 원료양 측정신호를 센싱하고 전송하는 로스셀 콘트롤러와; 로드셀 콘트롤러를 통해 전송받은 신호를 비교분선하고, 기준 질량이하 또는 이상일 때 알림신호를 전송하며, 로드셀 콘트롤러의 신호전송시, 원료공급부의 펌프/솔레노이드제어측으로 원료투입의 신호를 전송하고, 로드셀 콘트롤러의 기준 밀도값을 설정하며, 펌프/솔레노이드제어측의 원료투입이 작동되면 유무선통신망을 통해 사용자에게 요소수 투입신호 및 결과를 전송하는 제어부;로 형성된 것을 특징으로 한다. The system for quantifying urea water for diesel vehicles capable of maintaining a certain concentration according to the present invention comprises: a pure water device-a pure water storage tank-a diaphragm pump-a raw material supply unit through a pump / solenoid control; A mass sensing load cell unit for sensing the mass of the urea water supplied through the raw material supply unit; A loss cell controller that senses and transmits a signal for measuring the amount of raw material compared to the density; It compares and divides the signal transmitted through the load cell controller, transmits a notification signal when it is below or above the reference mass, and transmits a signal of raw material input to the pump/solenoid control side of the raw material supply unit when transmitting the signal from the load cell controller. And a control unit that sets a reference density value and transmits a signal for inputting urea water and a result to a user through a wired/wireless communication network when the raw material input from the pump/solenoid control side is operated.
본 발명은 제조사마다 다른 요소수의 농도를 일정한 농도로 유지하도록 함으로써, 자동차에 양질의 요소수를 공급함에 따라 불순물로 인해 발생되는 차량의 요소수 인젝터나 SCR 촉매의 막힘 또는 촉매 깨짐현상이 발생을 방지하고, 산화환원 과정에서 발생하는 요소수 고분자물질인 멜라니, 금속염 등이 SCR 내부는 물론 배기머플러 등에 쌓여 배압을 형성, 엔진 출력 및 연비를 떨어트리는 부작용 발생을 방지할 수 있고, 제조사마다 서로 다른 농도로 제조된 요소수의 농도를 일정하게 유지하도록 하여 SCR 촉매나 요소수 인젝터 노즐이 막히는 등 각종 부작용 발생방지 및 배출가스 정화능력 저하를 방지할 수 있는 효과가 있다.In the present invention, by maintaining the concentration of urea water different from manufacturer to manufacturer at a constant concentration, the occurrence of clogging of the urea water injector or the SCR catalyst of the vehicle caused by impurities or cracking of the catalyst due to the supply of high-quality urea water to the vehicle is prevented. It is possible to prevent, and prevent the occurrence of side effects that reduce engine output and fuel economy by accumulating in the SCR as well as in the exhaust muffler by urea water polymeric substances such as melany and metal salts, etc. By keeping the concentration of the urea water produced at a constant concentration, there is an effect of preventing the occurrence of various side effects such as clogging of the SCR catalyst or the urea water injector nozzle, and the reduction of exhaust gas purification ability.

이하, 첨부된 도면을 참조하여 본 발명의일정농도유지가 가능한 디젤차량용 요소수 정량화 생산시스템의 기술적 특징을 구체적으로 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the technical features of the production system for quantifying the number of urea for a diesel vehicle capable of maintaining a constant concentration of the present invention.
도 1은 일정농도유지가 가능한 디젤차량용 요소수 정량화 생산시스템의 공정도이다.1 is a flow chart of a production system for quantifying urea water for diesel vehicles capable of maintaining a constant concentration.
본 발명에 따른 일정농도유지가 가능한 디젤차량용 요소수 정량화 생산시스템은 원료공급부, 질량감지로드셀유닛, 로스셀콘트롤러, 제어부로 구성된다. The production system for quantifying the number of urea for a diesel vehicle capable of maintaining a constant concentration according to the present invention includes a raw material supply unit, a mass sensing load cell unit, a loss cell controller, and a control unit.
원료공급부는 순수장치-순수저장탱크-다이아프램펌프-펌프/솔레노이드제어를 통하여 용해조로 공급되어 로드셀 콘트롤러에 의해 제어부에서 설정된 일정농도의 요소수에 해당되는 요소수가 차량으로 공급된다. The raw material supply unit is supplied to the melting tank through the pure water device-pure water storage tank-diaphragm pump-pump/solenoid control, and the urea water corresponding to the urea water of a certain concentration set in the control unit by the load cell controller is supplied to the vehicle.
질량감지로드셀유닛은 일정농도의 요소수를 질량으로 감지하여 기준 질량을 통해 일정농도가 유지되도록 하는 것으로, 원료공급부를 통해 공급된 요소수의 질량을 감지한다. The mass sensing load cell unit detects the number of urea at a certain concentration as mass and maintains a certain concentration through the reference mass, and detects the mass of the urea water supplied through the raw material supply unit.
로스셀 콘트롤러는 질량감지로드셀유닛을 제어하면서 제어부로 밀도대비 원료양 측정신호를 센싱하고 전송한다. 또한, 제어부를 통해 질량감지로드셀유닛의 기준질량을 설정하도록 한다. While controlling the mass sensing load cell unit, the loss cell controller senses and transmits a measurement signal for the amount of raw material to the control unit. In addition, the reference mass of the mass sensing load cell unit is set through the control unit.
제어부는 로드셀 콘트롤러를 통해 전송받은 신호를 비교분선하고, 기준 질량이하 또는 이상일 때 알림신호를 전송하며, 로드셀 콘트롤러의 신호전송시, 원료공급부의 펌프/솔레노이드제어측으로 원료투입의 신호를 전송하고, 로드셀 콘트롤러의 기준 밀도값을 설정하며, 펌프/솔레노이드제어측의 원료투입이 작동되면 유무선통신망을 통해 사용자에게 요소수 투입신호 및 결과를 전송한다. The control unit compares and divides the signal transmitted through the load cell controller, and transmits a notification signal when it is below or above the reference mass, and when transmitting a signal from the load cell controller, it transmits a signal of raw material input to the pump/solenoid control side of the raw material supply unit, and the load cell It sets the reference density value of the controller, and when the raw material input from the pump/solenoid control side is operated, the urea water input signal and result are transmitted to the user through the wired/wireless communication network.
