As a result, more than twice as many deaths from traffic accidents are reportedly being killed by automobile smoke. Therefore, as part of greenhouse gas reduction, which has been steadily raised for a long time in developed countries, vehicle exhaust gas regulations are becoming stricter. Korea complies with European standards for 'light gas vehicle exhaust gas regulation'.

Therefore, Urea-SCR is economical because of the additional cost due to the use of urea water.
  • Urea-SCR system purifies nitrogen oxides in exhaust gas by injecting urea water through urea water injector while exhaust gas from diesel engine goes through SCR catalyst.

본 발명은 고체 상태의 요소와 액체 상태의 순수 또는 일반적으로 사용하는 물을 동시에 흡입하여 강제이송하는 방식을 통해 단시간 완전용해 가능하도록 하는 배관시스템을 갖추고 있어, 보다 효율적이면서 대량으로 고순도 요소수를 제조할 수 있으며, 이로써 자동차, 산업용 외에 선박용으로도 활용이 가능하여 산업상 이용가능성이 매우 큰, 자동차·선박·산업용 고순도 요소수 제조장치 및 이를 이용한 고순도 요소수 제조방법에 관한 것이다.The present invention is equipped with a piping system that allows for complete dissolution in a short time by a method of simultaneously suction and forced transfer of solid urea and liquid pure water or commonly used water to produce high purity urea water more efficiently and in large quantities. The present invention relates to a high purity urea water production apparatus for automobiles, ships, and industrial industries, which can be used for ships in addition to automobiles and industrials, and thus has high industrial applicability.
요소수(Urea)는 액상의 화학물질로서 우리가 흔히 알고 있는 요소비료의 원료인 요소(Urea)와 순수한 물(Water)을 혼합하여 만든 요소함량 32.5%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 is a liquid chemical that is 32.5% of urea made by mixing urea (Urea), which is a raw material of urea fertilizer, and pure water. This urea water is used to purify the nitrogen oxides of diesel engine cars. Nitrogen oxides cause various respiratory diseases such as bronchitis and pneumonia and are known as the main causes of optical smog and acid rain. As a result, more than twice as many deaths from traffic accidents are reportedly being killed by automobile smoke. Therefore, as part of greenhouse gas reduction, which has been steadily raised for a long time in developed countries, vehicle exhaust gas regulations are becoming stricter. Korea complies with European standards for 'light gas 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 보안할 수 있는 방식이 Urea-SCR 시스템이다.SCR catalyst system in automobile field can achieve more than 90% of DeNOx performance by using ammonia as reducing agent, but since ammonia is gaseous, it is difficult to store and it is almost impossible to use because it has adverse effects on human body due to leakage. Urea-SCR system is a way to secure the shortcomings of SCR system using ammonia as a 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.Urea-SCR is a technology for purifying nitrogen oxides using urea water. It is called DEF (Diesel Exhaust Fluid) in the United States and AdBlue in Europe. Urea water has a very large change in freezing point with temperature. When the concentration is 32.5%, the freezing point is the lowest as -11 ° C. Therefore, when setting the standard, the concentration of automotive urea is set to 32.5%, and the concentration of urea is set to 40% for ships and 40% for industrial use.
Urea-SCR 시스템의 자동차는 엔진이 가동되고 있으면 요소수가 지속적으로 사용되며, 이때 사용되는 양은 연료 대비 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 연비효과로 인하여 전체적인 운행경비는 Urea-SCR이 경제적이라 하겠다.The Urea-SCR system uses urea water continuously when the engine is running and consumes about 4-6% of the fuel used. In the system to cope with tightened emission regulations, SCR has improved fuel economy by an average of 3-5% over the EGR + DPF system. Therefore, Urea-SCR is economical because of the additional cost due to the use of urea water.
Urea-SCR 시스템은 디젤엔진에서 발생한 배기가스가 SCR 촉매장치를 거치는 과정에서 요소수 주입장치를 통해 요소수를 주입함으로써 배기가스 내의 질소산화물을 정화하게 된다.Urea-SCR system purifies nitrogen oxides in exhaust gas by injecting urea water through urea water injector while exhaust gas from diesel engine goes through SCR catalyst.
이와 같이 Urea-SCR 시스템에 사용되는 요소수를 제조함에 있어, 종래에는 요소의 용해를 위해, 자동차용 요소수의 경우 순수를 40℃까지 가온하는 방식을 취하였으며, 산업용 및 선박용은 40℃까지 가온하는 방식에 더하여 용해공정 과정에도 열을 공급하는 방식을 취하였다.As described above, in manufacturing urea water used in the Urea-SCR system, conventionally, in order to dissolve urea, pure water is heated to 40 ° C. for urea for automobiles, and 40 ° C. for industrial and ships. In addition to the method of applying the heat was also taken to the melting process.
요소는 용해 과정 중 흡열반응을 하며, 이로써 반응이 진행될수록 수온이 떨어지고, 온도가 떨어질수록 용해속도가 매우 낮아지기 때문에 일반 교반기 용해방식에서는 용해속도가 떨어지는 것을 방지하기 위해 가온을 하게 된다.The urea undergoes an endothermic reaction during the dissolution process. As the reaction proceeds, the water temperature drops, and as the temperature decreases, the dissolution rate becomes very low, so that the dissolution rate is lowered in the general stirrer dissolution method.
우리나라 4 계절 평균 수온이 10.5℃인 점을 감안할 때, 요소의 용해속도를 높이기 위해 순수 또는 물을 40℃까지 가온하는 방식은 에너지 소모량 매우 클 수밖에 없다.Considering that Korea's four season average water temperature is 10.5 ℃, the method of heating pure water or water up to 40 ℃ to increase the dissolution rate of urea requires very large energy consumption.
또한 종래의 가온 방식을 적용하기 위해서는 가열 설비 등의 부가설비의 증가가 불가피하여 요소수 제조장치가 전체적으로 대형화될 수밖에 없어 효율성 면에서 떨어지며, 이로 인한 제조단가의 상승으로 인해 경제성이 떨어진다.In addition, in order to apply the conventional heating method, it is inevitable to increase the additional equipment such as heating equipment, so that the urea water production apparatus must be large in size, resulting in a decrease in efficiency.
이외에 해외에서 사용되는 물순환방식에 의한 요소수 제조, 정제 기술은 요소의 용해가 제대로 이루어지지 않아 용해를 위한 시간이 30분 이상 소요되어 생산성 면에서 매우 비효율적이라는 단점이 있었으며, 특히 용해에 소요되는 시간이 늘어날수록 대기중의 CO2가 계속 주입되어 염이 생성되는 문제를 일으킨다.In addition, the urea water production and refining technology used in the water circulation method used abroad has a disadvantage that it is very inefficient in terms of productivity because it takes more than 30 minutes to dissolve because urea is not properly dissolved. Over time, atmospheric CO 2 continues to be injected, resulting in the formation of salts.
따라서, 요소수의 제조, 정제 기술에 있어 가온방식을 취하지 않거나 또는 취하더라도 보조적인 기능으로만 사용하여 단시간 내에 고순도의 요소수 제조, 정제장치의 보급이 필요한 실정이다.Therefore, in the production and refining technology of urea water, it is necessary to use a supplementary function even if the heating method is not used, or to supply urea water with high purity within a short time.
이와 같은 목적을 달성하기 위하여, 본 발명자는 2015년 06월 12일에 '고순도 요소수 제조장치 및 이를 이용한 고순도 요소수 제조방법'으로 특허출원(출원번호 10-2015-0083589)하여, 2015년 08월 07일에 등록(등록번호 10-1544503)받은 바 있다.In order to achieve the above object, the present inventors filed a patent (Application No. 10-2015-0083589) with a 'high purity urea water production apparatus and a high purity urea water production method using the same' on June 12, 2015, 2015 08 It was registered on July 07 (Registration No. 10-1544503).
본 발명자는 요소는 용해과정에 흡열반응으로 온도가 내려가며, 축온과 가스 발생이 없기 때문에 고체+액체 동시 순환방식의 이송을 하여도 문제가 없음을 연구를 통해 확인하였다.The present inventors confirmed that the urea has an endothermic reaction during the dissolution process, and since there is no storage temperature and no gas generation, there is no problem even when the solid-liquid simultaneous circulation is transported.
자동차용의 경우, 수온 17℃에서 용해를 시작하여 32.5%을 용해할 수 있다.In the case of automobiles, 32.5% can be dissolved by starting dissolution at a water temperature of 17 ° C.
그리고 선박용, 산업용의 경우, 수온 25℃에서 용해를 시작하여 40%까지 완전용해 할 수 있다. 이는 가온 설비가 없거나, 있더라도 가온 설비의 최소화로 에너지 사용량을 획기적 감소시킬 수 있음을 확인한 것이다.And in the case of marine and industrial, it can start dissolution at water temperature of 25 ℃ and completely dissolve up to 40%. This is to confirm that even if there is no heating equipment, even if the heating equipment is minimized, energy consumption can be drastically reduced.
즉, 본 발명자는 상기 등록특허의 용해 방식을 더욱 개선하여, 고체 상태의 요소와 액체 상태의 순수 또는 물을 동시에 흡입하여 강제이송, 완전용해 기능의 배관시스템을 개발하였으며, 또한 요소수고도정제부의 구성을 개선하여, 차량용·선박·산업용으로 적합한 고순도 요소수 제조장치를 완성하게 되었다.That is, the present inventors further improved the dissolution method of the registered patent, and developed a piping system of forced transfer and complete dissolution function by simultaneously sucking solid urea and pure water or water in a liquid state, and further, By improving the construction, a high-purity urea water production apparatus suitable for vehicles, ships, and industrial use is completed.

By secondary dissolution by vortex, it dissolves completely in a short time,
완전용해된 요소수를 저온용해방식으로 요소수 내의 불순물 뷰렛, 알데하이드, 불용성물질, 메탈이온 및 기타이온을 제거하여 고순도로 정제함으로써, 고순도 요소수를 효율적으로 생산하고, 단시간 내에 대량 생산이 가능하도록 하여 자동차, 일반 산업용 외에 대규모의 선박용으로도 활용할 수 있는,Completely dissolved urea water is purified at high temperature by removing impurity burettes, aldehydes, insolubles, metal ions and other ions in urea water by low temperature dissolution to efficiently produce high purity urea water and mass production in a short time. Can be used for large-scale ships in addition to automobiles and general industries,

본 발명에 따른 자동차·선박·산업용 고순도 요소수 제조장치 및 이를 이용한 고순도 요소수 제조방법은 다음의 효과를 갖는다.The high purity urea water production apparatus for automobiles, ships, and industries according to the present invention and the high purity urea water production method using the same have the following effects.
첫째. 펌프시스템부를 이용하여, 순수 또는 물과 고체 요소를 동시에 펌프에서 흡입하여 요소용해부의 상부와 하부로 강력 분사하고, 이때 발생하는 와류에 의해 강제 용해과정을 거침으로써, 단시간 내에 고체 요소의 완전용해를 이룰 수 있다는 장점을 갖는다. 또한 이와 같은 용해방식은 고체+액체를 동시에 이송함으로써 이송배관에서도 요소용해가 빠르게 일어난다.first. By using the pump system part, pure or water and solid urea are sucked out of the pump at the same time and sprayed strongly to the upper and lower parts of the urea melting part and forced dissolution by the vortex generated at this time, thereby completely dissolving the solid urea within a short time. It has the advantage that it can be achieved. In addition, this dissolution method is a solid + liquid transfer at the same time urea dissolution occurs quickly in the transfer pipe.
요소농도 32.5%인 자동차용의 경우, 순수의 온도가 17℃에서 요소를 투입하고 용해하여 요소수 온도가 영하 5℃까지 용해하는데 15분이 소요되며, 순수의 온도가 19℃에서 요소를 투입하고 용해하여 요소수 온도가 영하 3℃까지 용해하는데 10분이 소요된다.In the case of automobiles with a urea concentration of 32.5%, it takes 15 minutes for the urea water to be melted at 17 ° C by dissolving the urea and the urea water temperature to minus 5 ° C. It takes 10 minutes for the urea water temperature to melt to minus 3 ° C.
그리고 이와 같은 용해방식에 부가적으로 가온설비를 두어 순수의 온도가 40℃일때 요소를 투입하게 되는 경우, 투입 후 1분 30초 만에 완전 용해된다. In addition, if the urea is added when the temperature of pure water is 40 ° C. in addition to the dissolution method, it is completely dissolved in 1 minute and 30 seconds after the addition.
요소농도 40%인 산업용, 선박용에 본 발명에 따른 배관시스템을 적용하고, 물 온도를 기존 방식대로 40℃로 유지할 경우, 5분 경과 후 완전 용해된다.When the piping system according to the present invention is applied to industrial and marine urea concentrations of 40%, and the water temperature is maintained at 40 ° C. in the conventional manner, it is completely dissolved after 5 minutes.
그리고 물 온도를 낮춰 25℃로 유지하는 경우에는 20분 경과 후 완전 용해된다.When the water temperature is lowered and maintained at 25 ° C., it is completely dissolved after 20 minutes.
따라서, 본 발명에 따른 배관시스템을 적용하여, 수온 20℃이하의 자동차용과, 수온 28℃ 이하의 산업용 요소 용해에 소모되는 에너지 비용을 기존 대비 1/3로 절감할 수 있다.Therefore, by applying the piping system according to the present invention, it is possible to reduce the energy cost consumed for automotive urea below the water temperature of 20 ℃ and industrial urea melting below the water temperature of 28 ℃ to 1/3 compared to the conventional.
둘째. 자동차용의 경우 고체 요소 + 액체 순수의 강제 이송식 용해는 20℃ 이하의 저온 조건에서도, 기존 40℃의 고온 조건에서의 용해방식과 비교하여 단시간 내에 고순도의 요소수를 얻을 수 있다.second. In the case of automobiles, forced transfer dissolution of solid urea + liquid pure water can obtain urea water with high purity within a short time, even in the low temperature condition of 20 ° C. or lower, compared to the dissolution method in the high temperature condition of 40 ° C.
자동차용의 경우, 순수의 온도를 19℃ 이하로 하여 용해시, 요소의 뷰렛, 불용성물질, 알데하이드 용해가 되지 않으며, 또한 금속이온, 기타이온, 뷰렛등은 요소 용해과정 중에 요소수의 온도가 영하로 내려가면 재결정되어 0.2 MICRON 마이크로 필터의 필터링 만으로도 쉽게 제거할 수 있다. 이는 요소와 결합한 염들의 주요 특징이다. 따라서 자동차용의 경우 19℃ 이하의 저온 용해만으로도 고순도 요소수를 생산할 수 있다. In the case of automobiles, when the pure water temperature is lower than 19 ℃, the urea's burette, insoluble substance, and aldehyde are not dissolved, and the metal ions, other ions, and burette's temperature of the urea water is below freezing during the urea melting process. When it is lowered to, it is recrystallized and can be easily removed simply by filtering the 0.2 MICRON micro filter. This is the main feature of salts in combination with urea. Therefore, in the case of automotive, it is possible to produce high purity urea water only by melting at a low temperature below 19 ° C.
셋째. 본 발명은 단시간 내에 고체 요소를 완전용해시킬 수 있는 배관시스템을 갖추고 있어, 단시간 내에 완전용해를 이루고, 이와 같이 완전용해된 요소수를 중공사막필터(UF)를 이용하여 요소 용해과정 중에 미용해된 물질과 재결정 물질을 0.02micron 필터 처리방식으로 정제한다.third. The present invention has a piping system capable of completely dissolving the solid urea in a short time, complete dissolution in a short time, and the urea water is dissolved in the urea dissolution process using a hollow fiber membrane filter (UF) The material and recrystallized material are purified by 0.02 micron filter treatment.
이는 UF 후단부에 설치되어진 이온교환수지를 보호하기 위한 설치 순서이다. 다음 단계인 이온교환수지는 요소수 내의 불순물 이온들을 효과적으로 제거한다. 금속이온을 포함하여 이온성의 물질을 제거한다. 마지막 단계의 0.2 micron 필터는 이온교환수지에서 발생한 입자를 제거하기 위함이다.This is the installation procedure for protecting the ion exchange resin installed in the rear end of the UF. The next step, ion exchange resin, effectively removes impurity ions in urea water. It removes ionic materials including metal ions. The final 0.2 micron filter is used to remove particles from the ion exchange resin.
이와 같이 과정을 거쳐 요소수를 고도처리함으로써, 고순도 요소수의 대량생산이 가능하여 자동차용, 산업용 및 선박용으로도 적합하다는 장점이 있다.By highly processing the urea water through the process as described above, there is an advantage that it is possible to mass-produce high purity urea water, which is also suitable for automobiles, industrial and ships.
넷째. 본 발명에 따라 저온에서 완전용해되어 생산된 자동차용 요소수는 일정 시간이 지나더라도, 기존 제품과 달리 침전물(백탁현상)이 발생하지 않은 투명상태를 유지하는 고순도 요소수라는 장점이 있다.fourth. According to the present invention, the urea water for automobile produced by completely dissolving at a low temperature has an advantage of high purity urea water which maintains a transparent state in which a precipitate (cloudy phenomenon) does not occur unlike a conventional product after a certain time.
본 발명에 따라 제조된 고도정제된 요소수는, SCR-System에서 요소수로 인해 발생되는 촉매침착, 요소수 배기가스 배출구 막힘, 촉매기능 저하 등의 문제점을 효과적으로 막을 수 있다.The highly purified urea water prepared according to the present invention can effectively prevent problems such as catalyst deposition caused by urea water in the SCR-System, clogging of the urea exhaust gas outlet, deterioration of catalyst function, and the like.

상기 물공급부(10)는 그 선택에 있어 특별히 한정을 두지 않으며, 순수 또는 물 공급을 할 수 있는 장치라면 모두 사용이 가능하다.The water supply unit 10 is not particularly limited in the selection, any device capable of supplying pure water or water can be used.
단 상기 물공급부(10)를 통해 요소용해부(20)로 순수 또는 물을 공급함에 있어, 순수 또는 물에 포함되어 있는 이온물질이 제거되어 비저항치가 10MΩ.cm 이상이 것을 공급하도록 한다. 이와 같은 비저항치를 유지하기 위해 이온교환수지필터를 이용하여 정제된 것을 공급하는 것이 바람직하다.However, in supplying pure water or water to the urea solution 20 through the water supply unit 10, the ionic material contained in the pure water or water is removed to supply a specific resistance of 10 MΩ.cm or more. In order to maintain such a specific resistance value, it is preferable to supply the purified thing using an ion exchange resin filter.
물은 온도에 따라 비중이 달라지기 때문에 상기 물공급부(10)를 통해 요소용해부(20)로 공급되는 순수 또는 물은 온도에 따라 정확한 공급량을 계측하는 것이 중요하다.Since water has a specific gravity that varies depending on temperature, it is important to measure the amount of pure water or water supplied to the urea melting unit 20 through the water supply unit 10 according to the temperature.
상기 순수 공급양의 정확한 계측을 위하여, 상기 요소용해부(20)의 하단에는 요소용해부(20)의 하부 전면을 지지하면서 순수 또는 물의 공급량을 정확하게 계측할 수 있도록 설치하는 전자저울(401)과, 요소용해부(20) 내의 순수 또는 물의 양을 체크하기 위해 요소용해부(20)의 측벽에 설치되는 레벨게이지(402)와, 물공급부(10)와 요소용해부(20)를 연결하는 물공급관(100)의 일측에 설치되는 유량계(403)를 포함하는 정밀계측부(40)가 구성된다.In order to accurately measure the amount of pure water supplied, an electronic scale 401 is installed at the lower end of the urea melting unit 20 so as to accurately measure the amount of pure water or water while supporting the lower front surface of the urea melting unit 20. To check the amount of pure water or water in the urea melting unit 20, the level gauge 402 installed on the side wall of the urea melting unit 20, and the water connecting the water supply unit 10 and the urea melting unit 20. The precision measurement part 40 including the flow meter 403 provided in one side of the supply pipe 100 is comprised.
상기 정밀계측부(40)는 물의 온도에 따른 정확한 순수 또는 물 공급량의 정밀도를 높이기 위한 장치 구성으로서, 정확한 순수 또는 물 공급량은 전자저울, 레벨게이지, 유량계의 복합계측에 의한 정밀계측을 통해 달성된다. 이와 같이 순수 또는 물 공급량의 정밀 제어 목적은 무게분율로 요소를 용해시켜 요소의 농도를 정확하게 제어하기 위함이다.The precision measurement unit 40 is a device configuration for increasing the accuracy of the correct amount of pure water or water according to the temperature of the water, the exact amount of pure water or water is achieved through the precision measurement by the combined measurement of the electronic balance, level gauge, flow meter. As such, the purpose of precise control of the amount of pure water or water is to accurately control the concentration of urea by dissolving the urea in a weight fraction.
구체적인 예로서, 요소수는 농도가 32.5%일 때 빙점이 가장 낮기 때문에 사용상의 편리성이 뛰어나다. 이때 요소수의 농도를 32.5%로 만들기 위해서는 물 675Kg에 요소 325Kg을 정확하게 넣어야 한다. 따라서 정밀 계측에 의한 공급량이 정확하게 제어하여야 한다.As a specific example, urea water is excellent in convenience because the freezing point is the lowest when the concentration is 32.5%. At this time, to make the concentration of urea 32.5%, 325Kg of urea should be precisely put in 675Kg of water. Therefore, it is necessary to precisely control the supply amount by precision measurement.
상기 요소용해부(20)의 몸체(201) 상부 일측에는 고체상의 요소를 투입하기 위한 요소투입구(202)가 설치되어 있으며, 상부 다른 일측에는 가스배출관(203)이 형성되어 있어 상기 요소투입구(202)를 통해 고체상의 요소를 투입하고, 요소용해부(20)의 내에서 발생된 가스는 밸브에 의해 개폐되는 상기 가스배출관(203)을 통해 외부로 배출한다.An element inlet 202 is provided at one side of the body 201 of the element dissolving unit 20 to inject a solid element, and a gas discharge pipe 203 is formed at the other side of the element 20. The solid urea is inputted through), and the gas generated in the urea melting unit 20 is discharged to the outside through the gas discharge pipe 203 opened and closed by a valve.
상기 요소용해부(20) 내부로 투입되는 고체상의 요소는 종래 방식과 달리 와류에 의한 강제 용해방식에 의해 용해된다. 이와 같은 용해방식의 장점은 용해를 위한 열을 공급하지 않아도 되기 때문에 부가설비가 거의 없어 전체적으로 장치의 소형화가 가능하고, 겨울철과 같이 온도가 낮은 환경에서도 사용할 수 있다는데 있다. 그리고 기존 외국에서 사용되던 물순환방식과 비교하여 볼 때 10분 미만으로 요소수 제조, 정제시간을 단축시킬 수 있으며, 용해율을 높일 수 있어 요소수 생산에 있어 매우 효과적이다.The solid element introduced into the urea melting unit 20 is dissolved by a forced dissolution method by vortex, unlike the conventional method. The advantage of this dissolution method is that there is almost no additional equipment because it does not need to supply heat for melting, it is possible to miniaturize the device as a whole, it can be used in a low temperature environment, such as winter. Compared with the water circulation method used in foreign countries, the urea water production and purification time can be shortened to less than 10 minutes, and the dissolution rate can be increased, which is very effective in producing urea water.

도 2는 본 발명에 따른 자동차·선박·산업용 고순도 요소수 제조장치를 구성하는 요소용해부 내부에 액체 순수 또는 물과 고체 요소가 채워지는 과정을 도시한 개략도이다.Figure 2 is a schematic diagram showing the process of filling the liquid pure water or water and solid elements in the urea melting portion constituting the high purity urea water production apparatus for automobiles, ships, industrial according to the present invention.
요소용해부(20) 내부에 고체요소와 순수 또는 물을 채우는 과정을 살펴보면,Looking at the process of filling the solid urea and pure or water in the urea melting unit 20,
먼저 전자저울을 이용하여 필요 요소수 농도에 맞게 순수 또는 물을 채운다(도 2의 (a)). 그리고 도 2의 (b)에 도시된 바와 같이, 요소용해부(20) 안으로 고체 요소를 채운다.First, pure water or water is filled in accordance with the required concentration of urea using an electronic balance (FIG. 2A). And as shown in Figure 2 (b), the solid element is filled into the urea melting portion 20.
이때 요소용해부(20)에 연결되는 배관의 위치와 고체 요소 및 순수 또는 물의 채움 높이의 상호 관계는 중요하므로 이를 고려하여야 한다.At this time, the relationship between the position of the pipe connected to the element dissolution unit 20 and the filling height of the solid element and the pure water or water is important and should be considered.
즉, 도 2에 도시된 바와 같이, 제1배관(301)은 적어도 고체 요소가 채워져 있는 높이보다 높은 곳에 위치하여야 한다. 그리고 제2배관(302)은 요소용해부(20)의 하부에 위치한다.That is, as shown in FIG. 2, the first pipe 301 should be located at least above the height at which the solid element is filled. And the second pipe 302 is located under the urea solution 20.
이는 액체의 순수 또는 물과 고체의 요소를 개별적으로 흡입한 후, 상기 제1배관(301)이 제2배관(302)에 연결되는 지점에서, 액체의 순수 또는 물과 고체의 요소가 섞이면서 동시에 흡입한 후 강력분사하는 이젝팅 방식을 적용하기 위해서이다.It inhales the pure water of the liquid or the elements of water and solid separately, and at the point where the first pipe 301 is connected to the second pipe 302, the pure water of the liquid or the water and solid elements are mixed and suctioned at the same time. This is to apply the strong ejecting method.
먼저 강제이송펌프(307)에 의한 흡입이 시작되면, 먼저 제1배관(301)을 통해 순수 또는 물을 흡입하고, 바로 이어 제2배관(302)에 설치되어 있는 밸브를 개방하여 고체 요소를 흡입함으로써, 상기 제1배관(301)과 제2배관(302)이 만나는 지점에서부터 고체와 액체가 섞이면서 동시에 흡입하게 된다.First, when suction by the forced transfer pump 307 is started, firstly, pure water or water is sucked through the first pipe 301, and then the valve installed in the second pipe 302 is opened to suck solid elements. As a result, the solid and the liquid are mixed and suctioned at the same time from the point where the first pipe 301 and the second pipe 302 meet.
도 3에 도시된 바와 같이, 고체의 요소와 액체의 순수 또는 물이 혼합되어 있는 혼합물은 강제이송펌프(307)의 펌핑 작용에 의해, 제4배관(304)과 제5배관(305)을 거쳐 요소용해부(20) 내부로 강력분사하게 된다.As shown in FIG. 3, the mixture in which the solid urea and the pure water or water of the liquid are mixed is passed through the fourth pipe 304 and the fifth pipe 305 by the pumping action of the forced transfer pump 307. It is strongly sprayed into the element dissolution unit 20.
상기 제4배관(304)은 상기 제1배관(301) 보다 높은 위치에 연결되고, 상기 제5배관(305)은 고체 요소가 채워져 있던 높이보다 낮은 위치에 연결된다.The fourth pipe 304 is connected to a position higher than the first pipe 301, and the fifth pipe 305 is connected to a position lower than the height at which the solid element is filled.
상기 제4배관(304)과 제5배관(305)을 통해 강력 분사된 혼합물은 요소용해부(20) 내에서 와류를 형성하고, 이때 와류에 의한 강제 용해가 진행된다.The mixture strongly injected through the fourth pipe 304 and the fifth pipe 305 forms a vortex in the urea melting unit 20, whereby forced dissolution by the vortex proceeds.
도 4는 본 발명에 따른 자동차·선박·산업용 고순도 요소수 제조장치의 펌프시스템부를 보인 도면으로서, 펌프시스템부를 통해 순수 또는 물과 고체의 요소가 동시에 배관을 통해 강제이송되는 과정을 보인 도면이다.Figure 4 is a view showing a pump system of the high purity urea water production apparatus for automobiles, ships, industrial in accordance with the present invention, a diagram showing the process of forced transfer of pure or water and solid elements through the pipe at the same time through the pump system.
도 4에 도시된 펌프시스템부(30)는 도 2 및 도 3에 개략적으로 보인 배관 연결구조를 상세하게 도시한 도면이다.The pump system unit 30 shown in FIG. 4 is a view showing in detail the piping connection structure shown schematically in FIGS. 2 and 3.
제1배관(301)은 액체의 순수 또는 물을 흡입하는 배관이다.The first pipe 301 is a pipe for sucking the pure water or water of the liquid.
그리고 제2배관(302)은 고체의 요소를 흡입하는 배관이다. 상기 제2배관(302)에는 밸브가 설치되어 있어, 제1배관(301)을 통해 먼저 액체의 순수 또는 물을 흡입한 후 바로 상기 제2배관(302)에 설치되어 있는 밸브를 개방하여 고체의 요소가 흡입되도록 한다.The second pipe 302 is a pipe for sucking the solid element. The second pipe 302 is provided with a valve, the first intake of the pure water or water through the first pipe 301, and immediately after opening the valve installed in the second pipe 302 of the solid Allow the element to be inhaled.
도 4에 도시된 바와 같이, 상기 제1배관(301)은 제2배관(302)와 연결되며, 이로써 배관이 연결되는 지점에서, 액체의 순수 또는 물과 고체의 요소가 섞여 동시에 강제 이송된다.As shown in FIG. 4, the first pipe 301 is connected to the second pipe 302, whereby the pure water of the liquid or the water and the solid elements are mixed and forcedly transferred simultaneously.
이와 같이 액체의 순수 또는 물과 고체의 요소가 동시에 배관을 통해 강제 이송됨으로써, 강제 중에 지속적인 용해가 일어나며, 이와 같이 용해가 진행되고 있는 혼합상태의 요소와 순수 또는 물은 제3배관을 거쳐 제4배관(304)과 제5배관(305)을 통해 요소용해부(20)의 내측으로 강력분사된다.As such, pure liquid or water and solid elements of liquid are forced to be simultaneously transferred through the pipe, so that continuous dissolution occurs during forcing. Strongly sprayed into the urea solution 20 through the pipe 304 and the fifth pipe 305.
상기 제4배관(304)과 제5배관(305)에 의해 혼합상태의 요소와 순수 또는 물이 강력분사됨으로써 와류가 생성되고, 이와 같이 생성된 와류에 의해 고체 요소는 강제 용해방식에 의한 용해 속도가 더욱 빨라지게 된다.Vortex is generated by the strong spraying of urea in the mixed state and pure water or water by the fourth pipe 304 and the fifth pipe 305, and the solid urea is dissolved by the forced dissolution method. Will be faster.
상기 제1배관(301) 내지 제5배관(305)을 통한 흡입, 강제이송, 강력분사에 의한 와류 생성과정을 지속하다가, 고체 요소가 완전 용해된 시점이 되면, 상기 강제이송펌프(307)는 작동을 멈추게 된다.While the vortex generation process by suction, forced transport, and strong spraying through the first pipe 301 to the fifth pipe 305 is continued, when the solid element is completely dissolved, the forced feed pump 307 is It will stop working.
완전 용해된 요소수는 도 5에 도시된 바와 같이, 제2배관(302)과 제6배관(306)을 거쳐 요소수고도정제부(50)로 이송된다.As shown in FIG. 5, the completely dissolved urea water is transferred to the urea water purification unit 50 through the second pipe 302 and the sixth pipe 306.
이와 같은 펌프시스템부(30)에 의한 강제 이송과, 강력분사에 의해 발생하는 와류를 통한 완전용해방식은 등록특허 10-1544503에서 제시된 방법과 비교하여 용해시간을 단축시킬 수 있다는 장점과, 다량의 완전용해 요소수를 연속적으로 생성시킬 수 있다는 장점을 갖는다.Such a forced dissolution by the pump system unit 30, and the complete dissolution method through the vortex generated by the strong injection can reduce the dissolution time compared to the method proposed in Patent 10-1544503, and a large amount of It has the advantage of being able to continuously generate the total number of dissolved elements.
그리고 이와 같은 장점들에 의해, 용량이 상대적으로 큰 선박용에 적용하더라도 효과적으로 완전용해된 고도정제 요소수를 대량 생산할 수 있도록 한다.And by such advantages, it is possible to mass-produce highly dissolved high purity urea effectively even if applied to a relatively large ship.
상기 용해시간을 최대한 단축시켜야 하는 이유는 용해시간이 길어질수록 대기중의 CO2가 요소수에 계속 투입되어 염을 생성할 확률이 점점 높아지지 때문이다. 그리고 이는 요소수 품질 저하로 이어지게 되기 때문이다.The reason why the dissolution time should be shortened as much as possible is that the longer the dissolution time, the higher the probability of generating salts by continuously adding CO 2 to the urea water. This is because the urea water quality is lowered.
본 발명에 따른 강제 이송에 의한 강제용해방식을 따를 경우, 요소농도가 32.5%인 자동차용은 순수의 온도가 17℃일 때 요소를 투입하고 용해하여, 요소수의 온도가 영하 5℃가 될 때까지 용해하는데 15분이 소요된다.According to the forced dissolution method by the forced conveying according to the present invention, when the urea concentration of 32.5% for automobiles, when the temperature of pure water is 17 ℃ by adding and dissolving, when the temperature of the urea water is minus 5 ℃ It takes 15 minutes to dissolve.
순수의 온도가 19℃일 때 요소를 투입하고 용해하여, 요소수의 온도가 영하 3℃가 될 때까지 용해하는데 10분이 소요된다. It takes 10 minutes to dissolve urea when the pure water temperature is 19 ° C and dissolve until the temperature of urea water reaches minus 3 ° C.
그리고 순수의 온도가 40℃일 때 요소를 투입하게 되면, 1분 30초에 완전 용해된다. When urea is added when the pure water temperature is 40 ° C, it is completely dissolved in 1 minute and 30 seconds.
기존 산업용, 선박용 요소농도 40%에 적용시 기존 물 온도 40℃의 가온 방식에서는 완전 용해되는데 5분 가량이 소요된다. 그리고 25℃에서는 완전용해까지 20분 소요된다. When applied to 40% of existing industrial and ship's urea concentration, it takes about 5 minutes to dissolve completely in the heating method of existing water temperature of 40 ℃. And it takes 20 minutes to dissolve completely at 25 ℃.
이로써, 자동차용 등 20℃ 이하의 저온 용해방식과, 28℃ 이하의 산업용 용해방식에 의해 용해에 소모되는 에너지 비용을 종래 방식과 비교하여 보면, 본 발명에서 1/3 에너지 절감 효과를 갖는다.As a result, the energy cost consumed for melting by the low temperature melting method of 20 ° C. or lower and the industrial melting method of 28 ° C. or lower, compared with the conventional method, has a 1/3 energy saving effect in the present invention.
상기 요소용해부(20) 내에서 강제용해방식을 통해 제조된 요소수 내부에는 인, 칼륨, 철, 구리, 아연, 크롬, 니켈, 마그네슘, 나트륨, 칼륨 등의 불순물 이온들이 포함되어 있으며, 이와 같은 불순물을 제거하기 위해, 상기 요소수는 요소수고도정제부(50)로 이송되어 고도정제처리된다.The urea water prepared by the forced dissolution method in the urea melting unit 20 includes impurity ions such as phosphorus, potassium, iron, copper, zinc, chromium, nickel, magnesium, sodium, potassium, and the like. In order to remove impurities, the urea water is transferred to the urea water high purification unit 50 and is highly purified.
상기 요소수고도정제부(50)는 도 6에 도시된 바와 같이, 펌프시스템부(30)의 제6배관(306)을 통해 유입되는 완전용해 요소수를 공급받아 중곡사막으로 공급하는 정제부 펌프(501)와,As shown in FIG. 6, the urea water high purification unit 50 receives a completely dissolved urea water introduced through the sixth pipe 306 of the pump system unit 30 and supplies the purified urea pump to the middle grain desert ( 501),
상기 정제부 펌프(501)로부터 공급받은 완전용해 요소수를 1차 처리하는 중공사막(502)과,A hollow fiber membrane 502 for primary treatment of the completely dissolved urea water supplied from the purification unit pump 501,
상기 중공사막(502)에서 1차 처리된 완전용해 요소수를 2차 처리하는 이온교환수지(503)와,An ion exchange resin 503 for secondary treatment of the completely dissolved urea water firstly treated in the hollow fiber membrane 502,
상기 이온교환수지(503)를 통해 2차 처리된 완전용해 요소수를 3차 처리하는 마이크로필터(504)를 포함하여 이루어진다.It comprises a micro filter 504 for tertiary treatment of the complete dissolved urea water secondary treatment through the ion exchange resin (503).
상기 요소용해부(20)에서 생산된 요소수는 먼저 정제부 펌프(501)를 통해 중공사막(502)으로 투입된다.The urea water produced by the urea melting unit 20 is first introduced into the hollow fiber membrane 502 through the purification unit pump 501.
상기 중공사막(502)을 거친 요소수는 이온교환수지(503)로 이송된다. 이때 이온교환은 이온형 H,OH형의 혼합이온교환수지를 이용하는데 화학당량 즉 H 당량과 OH 당량이 1:1인 혼합수지를 이용한다.Urea water passed through the hollow fiber membrane 502 is transferred to the ion exchange resin (503). At this time, the ion exchange uses a mixed ion exchange resin of the ion type H, OH type, the chemical equivalent of H, OH and OH equivalent of 1: 1 mixed resin.
구체적인 예로서, 강산성양이온교환수지인 Stylrene과 Divinylbenzene의 Sulfonated Copolymer와 강염기성음이온교환수지로서 Stylrene과 Divinylbenzene의 4급아민화한 Copolymer의 혼합수지를 이용한다.As a specific example, a mixed resin of a sulfated copolymer of Stylrene and Divinylbenzene, which is a strong acid cationic exchange resin, and a quaternized aminated copolymer of Stylrene and Divinylbenzene, is used as a strong basic anion exchange resin.
이와 같이 화학적 당량적 1:1인 혼합수지를 사용하게 되면 pH 7을 유지하여 암모늄 염의 생성을 최소화하는 장점을 갖게 된다.As such, when the mixed resin having a chemical equivalent weight of 1: 1 is used, pH 7 is maintained to minimize the production of ammonium salts.
상기 이온교환수지(503)를 거친 요소수는 다시 마이크로 필터(504)로 이송되어 최종적으로 여과처리된다.The urea water passed through the ion exchange resin 503 is transferred to the micro filter 504 and finally filtered.
상기 고순도 요소수 제조장치(1)는 금속과 요소와의 반응을 통해 염이 석출되는 것을 방지하기 위하여 금속 대신 플라스틱 재질을 이용한다.The high-purity urea water production apparatus 1 uses a plastic material instead of metal to prevent the precipitation of salt through the reaction between the metal and the urea.
앞서 제시된 고순도 요소수 제조장치(1)를 이용한 고순도 요소수 제조과정을 살펴보도록 한다.Let us look at the high-purity urea water production process using the high-purity urea water production apparatus (1) presented above.
자동차·선박·산업용 고순도 요소수 제조과정은 물공급부(10) 내의 순수를 물공급관(100)을 통해 요소용해부(20)로 이송하는 단계(S10);The high purity urea water manufacturing process for automobiles, ships, and industry may include transferring pure water in the water supply unit 10 to the urea melting unit 20 through the water supply pipe 100 (S10);
상기 물공급부(10)로부터 요소용해부(20)로 공급되는 순수 또는 물의 공급량을 전자저울(401), 레벨게이지(402), 유량계(403)를 포함하는 정밀계측부(40)를 통해 정밀계측하는 단계(S20);Precise measurement of the amount of pure water or water supplied from the water supply unit 10 to the urea melting unit 20 through the precision measurement unit 40 including an electronic balance 401, a level gauge 402, and a flow meter 403.

상기 청구항 1의 펌프시스템부(30)의 제1배관(301)을 통해 먼저 순수 또는 물을 흡입한 후, 이어 제2배관(302)을 통해 요소용해부(20)의 하부에 채워져 있는 고체 요소를 흡입하여 상기 제1배관(301)과 제2배관(302)이 연결되는 지점에서, 고체요소와 액체 순수 또는 물이 혼합되면서 동시에 이송되고, 제3배관(303)을 통해 강제이송펌프(307)을 거쳐 제4배관(304) 및 제5배관(305)을 통해 요소용해부(20) 내부로 강력분사하여 와류를 형성함으로써, 강제 이송과정 중의 용해와, 와류에 의한 강제 용해에 의해 완전 용해를 이루는 단계(S40);Solid element filled in the lower part of the urea melting unit 20 through the first pipe 301 of the pump system unit 30 of claim 1 and then sucked the pure water or water through the second pipe 302 first At the point where the first pipe 301 and the second pipe 302 are connected by suctioning, the solid element and the liquid pure water or water are simultaneously mixed and transferred, and the forced transfer pump 307 through the third pipe 303. Through the fourth pipe 304 and the fifth pipe 305 into the urea melting portion 20 to form a vortex, thereby completely dissolving by dissolution during forced conveyance and forced dissolution by vortex Forming a step (S40);
상기 완전용해 단계(S40) 이후, 요소용해부(20)의 하부에 연결되어 있는 제2배관(302)과, 상기 제2배관(302)과 일체로 연결되어 있는 제6배관(306)을 통해 완전용해된 요소수를 요소수고도정제부(50)로 이송하는 단계(S50);After the complete melting step (S40), through the second pipe 302 is connected to the lower portion of the urea melting unit 20, and through the sixth pipe 306 is integrally connected to the second pipe 302 Transferring the completely dissolved urea water to the urea water purification unit 50 (S50);
상기 요소수고도정제부(50)로 공급된 완전 용해 요소수를 중공사막(502), 이온교환수지(503) 및 마이크로필터(504)를 순차적으로 거쳐 고도 정제 처리하는 단계(S60);를 포함하여 이루어진다.Including the step of completely purifying the completely dissolved urea water supplied to the urea water high purification unit 50 through the hollow fiber membrane 502, the ion exchange resin 503, and the micro filter 504 (S60); Is done.
이와 같이 요소수고도정제부(50)를 거쳐 최종적으로 제조된 고순도 요소수는 자동차용, 산업용 및 선박용 촉매 첨가제로 이용된다.The high purity urea water finally produced through the urea water high purity purification unit 50 is used as a catalyst additive for automobiles, industrial use, and ships.
이와 같은 과정을 거쳐 생산된 고순도 요소수는 주유소, 버스터미널, 화물터미널, 중장비 회사, 전세버스 운용회사, 화물/버스 차고지 외에 요소수를 필요로 하는 사업장 또는 선박용으로 다양하게 활용할 수 있다는 장점을 갖는다.The high purity urea water produced through this process has the advantage that it can be used in various fields such as gas stations, bus terminals, cargo terminals, heavy equipment companies, chartered bus operators, cargo / bus garages, and other businesses that require urea water. .
상기 선박용의 경우 다른 사업장에 적용하는 경우보다 규모가 커지는 것 외에 그 장치 구성은 동일하다.In the case of the ship, the size of the apparatus is the same except that the scale is larger than that in other workplaces.
이상에서 살펴본 선박·산업용 고순도 요소수 제조장치(1)는 제1실시예에 따른 것으로서, 도 7에 도시된 바와 같이, 교반기 또는 가열기가 설치되어 있지 않다.The apparatus for manufacturing high purity urea water 1 for ships and industries described above is according to the first embodiment, and as shown in FIG. 7, no stirrer or heater is provided.
하지만, 본 발명에 따른 선박·산업용 고순도 요소수 제조장치(1)에 교반기와 가열기를 보조적 기능의 장치로 설치한다면 더욱더 완전 용해에 따른 시간을 단축시킬 수 있다.However, if the stirrer and the heater are installed in the vessel and industrial high purity urea water production apparatus 1 according to the present invention as an auxiliary function, the time for complete dissolution can be further shortened.
도 8은 본 발명의 제2실시예에 따른 선박·산업용 고순도 요소수 제조장치(1)의 요소용해부(20)를 보인 정면도이다.8 is a front view showing the urea melting portion 20 of the high purity urea water production apparatus 1 for ships and industries according to the second embodiment of the present invention.
도 7에 도시된 제1실시예의 요소용해부(20) 내에 가열기(21)가 더 설치되어 이루어진 형태이다.The heater 21 is further provided in the element melting part 20 of the first embodiment shown in FIG.
우리나라 4계절 평균 수온은 10.5℃로서, 요소수의 용해 효율을 높이기 위해서는 요소수 용해에 사용되는 물의 수온이 최소 17℃ 이상이 되어야 한다.Korea's four season average water temperature is 10.5 ℃, and in order to improve the dissolution efficiency of urea water, the water temperature of urea water must be at least 17 ℃.
따라서 요소수 용해에 사용되는 물을 물공급부(10)에서 가열장치를 통해 사전에 수온을 일정온도 이상으로 높인 후에 요소용해부(20)로 공급하거나 또는 요소용해부(20) 내부에 가열장치를 구비하여 수온이 25~40℃의 범위 내에서 유지되도록 한다.Therefore, the water used for dissolving urea water is raised in advance in the water supply unit 10 through a heating device, and then supplied to the urea melting unit 20 or a heating device inside the urea melting unit 20. Equipped to keep the water temperature in the range of 25 ~ 40 ℃.
수온이 높을수록 용해가 잘 되나 불필요한 이물질이 함께 용해되어 순도가 떨어지는 문제가 발생하게 되기 때문에 상기 제시된 범위 내에서 수온을 유지하는 것이 바람직하다.It is preferable to maintain the water temperature within the above-mentioned range because the higher the water temperature, the better the solubility but the unnecessary foreign matters are dissolved together and the problem of lower purity occurs.
다음으로, 본 발명의 제3실시예에 따른 선박·산업용 고순도 요소수 제조장치(1)에 대해 살펴보도록 한다.Next, a high-purity urea water production apparatus 1 for ships and industries according to a third embodiment of the present invention will be described.
