본 발명은 해수담수화설비용 탈기기의 보충수 분배관 구조에 관한 것으로, 더욱 상세하게는 보충수 분배관에 구멍을 형성하여 보충수의 분배가 원활하게 이루어지도록 한 것이다. The present invention relates to the structure of the replenishment water distribution pipe of the dewatering apparatus for seawater desalination plant, and more particularly, to form a hole in the replenishment water distribution pipe to facilitate the distribution of the replenishment water.

일반적으로 해수담수화설비는 몇가지 방식에 의해 이루어지는데, 그중에서 다단증발법(Multi Stage Flashing Method; 이하 "MSF"라 약칭함)을 많이 이용한다. 이 MSF를 이용하는 경우에는 해수를 끌어들여 이를 증발하기 위한 증발기(Evaporator)가 상당히 중요한 구성요소이다. 이 증발기는 스팀의 열에너지를 이용하여 가열된 해수로부터 연속적인 증발, 응축의 과정을 통하여 담수를 분리하는 장치이다. 이 증발기는 여러 개(19개 ~ 30개)의 스테이지(Stage)로 이루어져 있고, 각각의 스테이지는 응축기(Condenser), 기수분리기(Demister) 및 증발실(Flashing Chamber)로 구성되어 있다. In general, the seawater desalination plant is made by several methods, among which a multi-stage flashing method (hereinafter, abbreviated as "MSF") is frequently used. When using this MSF, an evaporator to attract and evaporate seawater is a very important component. This evaporator is a device that separates fresh water from the heated seawater by continuous evaporation and condensation using steam thermal energy. This evaporator consists of several stages (19-30), each stage consisting of a condenser, a demister and a flashing chamber.

또한, 증발기의 일측에는 해수가열기(Brine Heater)가 갖추어지는데, 이 해수가열기는 증발기를 순환하며 예열된 순환농염수(Brine)를 스팀의 열 에너지를 이용하여 운전온도로 가열하는 장치이다. In addition, one side of the evaporator is equipped with a Brine Heater (Brine Heater), which is a device for circulating the evaporator to heat the preheated circulating brine (Brine) to the operating temperature using the thermal energy of steam.

또한, 증발기의 다른 한편에는 탈기기(Deaerator)가 설치된다. 이 탈기기는 증발기의 마지막 스테이지(Stage)로 유입되는 보충수(Make-up)에 포함되어 있는 이산화탄소 및 산소를 제거하는 장치이다.Also on the other side of the evaporator is a deaerator. This deaerator is a device that removes carbon dioxide and oxygen contained in make-up flowing into the final stage of the evaporator.

첨부된 예시도면 도 1은 이러한 탈기기를 나타낸 도면으로서, 탈기기본체(10)의 내부 중앙에는 충전재(Pall Packing)(11)가 채워지고, 그 아래에는 상기 충전재(11)를 지지하는 서포트플레이트(12)가 구비되며, 이 서포트플레이트(12)의 상부에는 스팀이 공급되는 연결파이프(13)가 다수 형성되어 있고, 서포트플레이트(12)의 하부에는 스트립핑 스팀파이프(Stripping Steam Pipe)(14)가 구비되어서 상기 연결파이프(13)와 각각 연통되게 연결되어 있다.1 is a view illustrating such a degassing apparatus, in which an inner center of the degassing body 10 is filled with a filling packing 11, and a support plate for supporting the filling 11 below. 12 is provided, a plurality of connecting pipes 13 through which steam is supplied is formed on the upper part of the support plate 12, and a stripping steam pipe 14 is provided on the lower part of the support plate 12. Are provided to be connected to each of the connection pipes (13).

상기 충전재(11)는 작은 알갱이 형태를 이루면서 수만개(약 4만여 개)가 채워진다. The filler 11 is filled with tens of thousands (about 40,000 pieces) while forming small grains.

한편, 상기 충전재(11)의 상부에는 보충수가 공급되어 분사되도록 하는 보충수 분배관(15) 및 노즐(16)이 설치되어 있다.On the other hand, the top of the filler 11 is provided with a supplemental water distribution pipe 15 and the nozzle 16 to be supplied and sprayed.

도면에서 미설명부호 20은 분배관(15)을 고정시키는 U볼트이다. In the drawing, reference numeral 20 denotes a U bolt for fixing the distribution pipe 15.

상기 분배관(15)의 노즐(16)을 통해 분사되는 보충수는 충전재(11)를 통과하면서 보충수에 포함되어 있는 이산화탄소 및 산소가 상기 충전재(11)의 표면에 붙게되면서 제거되고, 이산화탄소 및 산소가 제거된 공급수는 아래쪽으로 떨어지게된다. 이러한 과정을 거친 보충수는 증발기안으로 유입된다. The replenishment water injected through the nozzle 16 of the distribution pipe 15 is removed while the carbon dioxide and oxygen contained in the replenishment water adhere to the surface of the filler 11 while passing through the filler 11, and the carbon dioxide and Oxygen-free feed water drops downward. After this process, the make-up water is introduced into the evaporator.

여기서, 상기 탈기기본체(10)의 내부에 갖추어진 스트립핑 스팀파이프(13)(14)는 분사되는 보충수를 한번 더 데워주는 역할을 한다. Here, the stripping steam pipes 13 and 14 provided in the degassing base body 10 serve to warm the injected supplementary water once more.

이러한 종래의 탈기기는 직접 해수와 접촉하게되므로, 부식이 잘 되지 않는 스테인레스재를 사용하게 된다. Since the conventional deaerator comes in direct contact with seawater, stainless steel that is not easily corroded is used.

따라서, 보충수를 분배하는 보충수 분배관(15)은 고가의 제품이되고, 아울러 노즐(16)도 고가의 제품이 될 수 밖에 없는 것이다. Therefore, the replenishment water distribution pipe 15 for distributing the replenishment water becomes an expensive product, and the nozzle 16 also becomes an expensive product.

따라서, 제품의 단가가 상승하는 요인으로 작용하는 등의 문제점이 있었다.
또한, 노즐을 통한 분사시, 미세하고 고른 분사가 이루어지기 어려워 탈기량의 증대가 불가능하고, 더욱이 노즐이 차지하는 길이만큼 분사되는 보충수의 자유낙하거리가 짧아져서 탈기효율이 증대되기 어려운 문제점이 있었다. Therefore, there has been a problem that the unit price of the product acts as a factor that increases.
In addition, when spraying through the nozzle, it is difficult to increase the amount of degassing because it is difficult to achieve fine and even spraying, and furthermore, there is a problem that the free fall distance of the supplementary water injected by the length of the nozzle is shortened, so that the degassing efficiency is difficult to increase. .

이에 본 발명은 상기와 같은 종래의 제반 문제점을 해소하기 위해 발명된 것으로서, 보충수 분배관에 부착된 노즐을 제거하고, 구멍만을 형성하여 압력차에 의해 보충수의 분배가 이루어지도록 하므로써 저렴한 가격의 제품을 제공할 수 있도록 한 해수담수화설비용 탈기기의 보충수 분배관 구조를 제공함에 그 목적이 있다. The present invention has been invented to solve the conventional problems as described above, by removing the nozzle attached to the replenishment water distribution pipe, by forming only holes to distribute the replenishment water by the pressure difference is low price The purpose is to provide a supplementary water distribution pipe structure for degassing equipment for seawater desalination equipment to provide products.

상기와 같은 목적을 달성하기 위한 본 발명은 해수담수화설비용 탈기기에 있어서, 탈기기 본체의 내부에 설치되는 보충수 분배관에 다수의 분사공을 형성한 것을 기술적 특징으로 한다. The present invention for achieving the above object is characterized in that in the dewatering apparatus for seawater desalination plant, a plurality of injection holes formed in the supplemental water distribution pipe installed in the degasser main body.

이하 본 발명의 바람직한 실시예를 첨부된 예시도면에 의거 상세히 설명한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 탈기기용 분배관 구조를 나타낸 단면도, 도 3은 본 발명에 따른 분배관 의 구조를 확대도시한 단면도이다.Figure 2 is a cross-sectional view showing the structure of the distribution pipe for deaerator according to the present invention, Figure 3 is an enlarged cross-sectional view showing the structure of the distribution pipe according to the present invention.

도면에 도시된 바와 같이, 본 발명은 탈기기본체(10)의 내부에 보충수를 분배하도록 하는 분배관(15)들이 여러개 소정간격을 두고 설치되어 있는데, 이 분배관(15)에는 다수의 분사공(15a)이 형성된 구조이다. As shown in the figure, the present invention is provided with a plurality of distribution pipes 15 for a predetermined interval to distribute the replenishment water in the degassing main body 10, a plurality of distribution pipes 15 The hole 15a is formed.

이러한 분사공(15a)을 통해서 보충수가 분사되어 하부로 낙하되도록 한 것이다. Replenishment water is injected through these injection holes (15a) to fall to the bottom.

이러한 구성을 가지는 본 발명은 종래와 같이 별도의 분사용 노즐이 분배관(15)에 각각 설치되지 않고, 간단히 분사공만을 형성하여 보충수가 분사되게 하므로써, 고가의 스테인레스재를 사용하는 노즐의 비용을 절감할 수 있고, 설치작업도 매우 간편해지는 것이다.
또한, 보충수의 분사시 자유낙하높이가 종래에 비해 상대적으로 증가되므로, 그 만큼, 탈기효율이 증대되고, 미세하고 고른 분사에 의한 표면적의 증가로 인한 탈기량의 증대가 가능한 것이다. The present invention having such a configuration is not provided with separate injection nozzles in the distribution pipe 15 as in the prior art, and simply forms only injection holes so that supplemental water is injected, thereby reducing the cost of nozzles using expensive stainless materials. It can be saved and installation is much easier.
In addition, since the free fall height during the injection of the replenishment water is relatively increased in comparison with the related art, the degassing efficiency is increased, and the degassing amount is increased due to the increase in the surface area by the fine and even spraying.

이와 같이 본 발명은 고가의 스테인레스재를 사용하는 종래의 노즐을 없애고, 간단히 보충수분배관에 구멍을 형성하여 압력차에 의해 보충수가 분배되도록 하므로써 저렴한 가격의 제품을 제공할 수 있는 장점이 있는 것이다.
또한, 자유낙하높이를 증대시켜서 탈기효율이 증대되고, 미세하고 고른분사에 의한 표면적의 증가로 탈기량의 증대가 가능한 효과가 있다. As such, the present invention eliminates the conventional nozzle using an expensive stainless material, and has an advantage of providing a low-cost product by simply forming a hole in the replenishment water distribution pipe so that the replenishment water is distributed by a pressure difference.
In addition, the degassing efficiency is increased by increasing the free fall height, and the degassing amount can be increased by increasing the surface area by fine and even spraying.

이상 본 발명은 편의상 첨부된 예시도면에 의거 상세히 설명하였지만, 이에 국한되지 않고 본 발명의 기술적 사상의 범주내에서 여러가지 변형 및 수정이 가능함은 자명한 사실이다.
Although the present invention has been described in detail based on the accompanying drawings for convenience, it is obvious that various modifications and changes are possible without departing from the scope of the technical idea of the present invention.
