Description

요소수 제조장치{Urea water manufacturing apparatus}Urea water manufacturing apparatus

본 발명은 요소수 제조장치에 관한 것으로, 보다 상세하게는 제염 공정 중 농축기에서 발생되는 수증기를 응축시킨 증류수에 요소를 혼합하는 공정을 결합하여 대기 중으로 배출되는 증류수를 사용하여 요소수의 제조 비용을 절감하도록 할 수 있는 요소수 제조장치에 관한 것이다.The present invention relates to an apparatus for producing urea water, and more particularly, by combining the process of mixing urea with distilled water obtained by condensing water vapor generated in the concentrator during the decontamination process, the manufacturing cost of urea water is reduced by using distilled water discharged into the atmosphere. It relates to an apparatus for producing urea water that can be reduced.

요소수(尿素水, Urea)는 액상의 화학물질로서 우리가 흔히 알고 있는 요소비료의 원료인 요소(Urea)와 순수한 물(Water)을 혼합하여 만든 화학물질로 농도 31.8~33.2%의 자동차 요소수와 40%의 선박 및 산업용 요소수가 있으며, 주로 질소산화물을 정화하는데 사용된다.Urea water (尿素水, Urea) is a liquid chemical substance made by mixing urea, the raw material of urea fertilizer, and pure water, which are commonly known as automobile urea water with a concentration of 31.8 to 33.2%. and 40% of marine and industrial urea water, mainly used to purify nitrogen oxides.

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. 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 is a report that more than twice the number of people who died in traffic accidents are killed by automobile exhaust gas.

이에, 선진국을 중심으로 오래전부터 꾸준히 제기되어 온 온실가스감축의 일환으로 차량배기가스 규제가 점점 엄격해 지고 있으며, 우리나라도 '경유자동차배기가스규제'로 유럽기준을 따르고 있다.Accordingly, vehicle exhaust gas regulations are getting stricter as part of greenhouse gas reduction, which has been steadily raised in developed countries for a long time.

한편, 요소수는 생산과정에서 요소(Urea)와 초순수를 혼합하는 것에 의해 제조되는데, 종래의 요소수 제조장치는 대부분 고체 요소와 순수를 혼합하여 강제 순환시키는 방식으로서, 별도의 원수를 연수기를 이용하여 순수로 제조한 후 고체의 요소가 소정의 농도로 용해되도록 하는 공정을 가지고 있다.On the other hand, urea water is produced by mixing urea and ultrapure water in the production process. Most of the conventional urea water production apparatuses mix solid urea and pure water for forced circulation, and separate raw water is used in a water softener. It has a process of making it into pure water and then dissolving the solid urea to a predetermined concentration.

그러나 종래의 요소수 제조장치는, 단순히 상온 상태의 원수를 연수기를 이용하여 이온 교환시키는 것을 통해 순수를 제조하고 있는데, 원수에 불순물이 많이 포함되어 있는 경우 연수 과정에 많은 시간과 비용이 소요되는 문제점이 있다.However, in the conventional urea water production apparatus, pure water is produced by simply ion-exchanging raw water at room temperature using a water softener. There is this.

한편, 종래의 제염장치는, 용해된 지하수와 소금의 혼합물인 염수를 증발 및 농축시키는 과정을 통하여 소금 또는 꽃소금이 제조되도록 하고 있는데, 염수의 증발 및 농축 공정에서 소금기가 제거되고 불순물이 제거된 순수 상태의 증류수가 대기 중으로 그대로 배출되도록 하고 있다.On the other hand, in the conventional decontamination apparatus, salt or flower salt is produced through a process of evaporating and concentrating brine, which is a mixture of dissolved groundwater and salt. The distilled water in the state of being discharged into the atmosphere as it is.

이에, 요소수의 제조에 있어서, 많은 비용과 시간을 소비하면서 순수를 제조하는 공정을 제염 또는 재제염 공정에서 대기 중으로 그대로 배출되는 증류수를 사용하는 것으로 대체하여 요소수의 제조 비용을 절감하도록 할 수 있는 방안이 대두되고 있다.Therefore, in the production of urea water, it is possible to reduce the manufacturing cost of urea water by replacing the process of producing pure water while consuming a lot of money and time with using distilled water that is directly discharged into the atmosphere in the decontamination or re-decontamination process. A plan is being discussed.

충전재는, 알루미나(Al2O3), 질화붕소(BN), 질화알루미늄(AlN), 질화규소(Si3N4), 마그네시아(MgO), 베릴리아(BeO), 산화아연(ZnO), 탄화규소(SiC),지르코니아(ZrO2) 및 그 혼합물로 이루어진 군에서 선택된다.The filler is alumina (Al 2 O 3 ), boron nitride (BN), aluminum nitride (AlN), silicon nitride (Si 3 N 4 ), magnesia (MgO), beryllia (BeO), zinc oxide (ZnO), silicon carbide (SiC), zirconia (ZrO 2 ) and mixtures thereof.

내열제는, 나노실리카와 아크릴기를 포함하는 화합물일 수 있다.The heat resistance agent may be a compound including nano-silica and an acryl group.

여기서, 중합체 100중량부에 충전재 70중량부가 첨가되도록 하는 것은, 충전재가 상기 중량부를 미만하는 경우에는 열전도 효율이 저하되고, 상기 중량부를 초과하는 경우에는 점도 범위를 유지할 수 없어 셰브런(미도시)의 표면에 코팅시 작업성이 저하되는 문제점이 있으므로, 상기와 같은 임계적 의의를 가지는 것이 좋다.Here, 70 parts by weight of the filler is added to 100 parts by weight of the polymer, when the filler is less than the above weight part, the heat conduction efficiency is lowered, and when it exceeds the above weight part, the viscosity range cannot be maintained, so Chevron (not shown) Since there is a problem that workability is reduced when coating the surface of the, it is good to have the critical significance as described above.

또한, 충전재는, 평균입경이 10 내지 30㎛의 범위를 가지는데, 상기 범위를 가지는 경우 상기 중합체와의 혼합시 적절한 점도 범위를 유지할 수 있어 셰브런(미도시)의 표면에 코팅시 작업성을 확보할 수 있고 최종적으로 셰브런(미도시) 표면이 매끈하게 유지될 수 있으므로, 상기와 같은 임계적 의의를 가지는 것이 좋다.In addition, the filler has an average particle diameter in the range of 10 to 30 μm. When it has the above range, it is possible to maintain an appropriate viscosity range when mixed with the polymer, so that the workability is improved when coating on the surface of the Chevron (not shown). Because it can be secured and finally the chevron (not shown) surface can be kept smooth, it is good to have the critical significance as described above.

또한, 중합체 100중량부에 내열제가 20중량부가 첨가되도록 하는 것은, 내열제가 상기 중량부를 미만하는 경우에는 내열 특성이 제대로 발현되지 못하여 셰브런(미도시)이 내화되어 열전도율이 저하되거나 상기 부식방지용폴리머가 쉽게 박리되며, 상기 중량부를 초과하는 경우에는 내열 성능은 우수해지지만 냉각사이클의 증발기로부터 전달되는 전도율이 저하되어 응축 성능이 저하될 수 있으므로, 상기와 같은 임계적 의의를 가지는 것이 좋다.In addition, the reason that 20 parts by weight of the heat resistant agent is added to 100 parts by weight of the polymer is that, when the heat resistant agent is less than the above weight, the heat resistance properties are not properly expressed, so that the chevron (not shown) is fireproof and the thermal conductivity is lowered or the anti-corrosion polymer is easily peeled off, and when it exceeds the above weight part, heat resistance performance is excellent, but the conductivity transmitted from the evaporator of the cooling cycle is lowered, so that the condensation performance may be lowered, so it is good to have the above critical significance.

이에, 셰브런(미도시)에 상기와 같은 부식방지용폴리머가 코팅되는 경우, 수증기의 수분이 셰브런(미도시)의 표면에 직접 접촉되지 않으면서도 응결 또는 결로되도록 하여 셰브런(미도시)의 부식을 방지할 수 있다.Accordingly, when the chevron (not shown) is coated with the anti-corrosion polymer as described above, the moisture of the water vapor condenses or dews without directly contacting the surface of the chevron (not shown). It can prevent corrosion.

따라서 증류수생성부(210)에 의하면, 농축부(130)로부터 배출되는 수증기를 응축시켜 증류수를 생성함으로써, 외부로 배출되는 수증기가 백연화되는 것을 방지할 수 있고 순수로 재활용하여 요소수의 제조 비용이 절감되도록 할 수 있다. Therefore, according to the distilled water generating unit 210, by condensing the water vapor discharged from the concentrating unit 130 to generate distilled water, it is possible to prevent the water vapor discharged to the outside from whitening, and to reduce the manufacturing cost of urea water by recycling it as pure water. can be made to be reduced.

이하, 상기와 같은 구성을 가지는 요소수 제조장치의 작용에 대해 설명하면 다음과 같다. Hereinafter, the operation of the urea water production apparatus having the above configuration will be described as follows.

먼저, 지하수에 천일염이 용해되어 염수가 제조된 후, 농축부(130)를 통해 염수가 농축된 상태에서, 원심분리부(150)를 통해 재제염이 제조된다.First, sea salt is dissolved in groundwater to prepare brine, and then, in a state in which the brine is concentrated through the concentrator 130 , re-salt is prepared through the centrifugation unit 150 .

한편, 농축부(130)를 통한 염수의 농축시, 증류수생성부(210)에 의해, 농축부(130)로부터 증발되는 수증기가 집진된 후 응축되면서 증류수로 집수된다.On the other hand, when the brine is concentrated through the concentrating unit 130 , the water vapor evaporated from the concentrating unit 130 is collected by the distilled water generating unit 210 and then condensed and collected as distilled water.

이후, 증류수에 요소가 혼합되어 요소수가 제조된다.Thereafter, urea is mixed with distilled water to prepare urea water.

따라서 본 발명에 의하면, 요소수의 제조를 위한 순수가 제염 공정에서 대기 중으로 배출되는 수증기가 응축되면서 생성되는 증류수로 대체되는 것을 통해 확보됨으로써, 많은 비용과 시간을 소비하면서 순수를 제조하지 않아도 되어 요소수 제조 공정과 비용을 단축시킬 수 있고, 제염 공정 중 버려지는 수증기도 재사용할 수 있다.Therefore, according to the present invention, pure water for the production of urea water is secured by being replaced with distilled water generated while water vapor discharged to the atmosphere in the decontamination process is condensed, so that it is not necessary to manufacture pure water while consuming a lot of money and time. The water production process and cost can be shortened, and the steam discarded during the decontamination process can be reused.
