본 발명에 따른 가스 냉각 장치는 특히, 냉각탑, 습식정화장치 등에서 배출되는 수증기를 함유한 가스를 차갑게 냉각하여 백연을 제거하는 백연 제거 장치로서 활용될 수 있다.In particular, the gas cooling device according to the present invention may be utilized as a white smoke removal device that cools a gas containing water vapor discharged from a cooling tower, a wet purifier, and the like to remove white smoke.
다양한 플랜트, 공장, 빌딩 등에서 대량으로 사용되는 물을 냉각시키기 위한 냉각탑의 수요가 점점 늘어나고 있다. 냉각탑은 상단부의 배기구에 설치된 송풍기를 이용해서 외부 공기를 냉각탑 내부로 유입시키고, 냉각탑의 내부에 노즐을 이용해서 피냉각수를 분사시켜, 피냉각수와 외부 공기 사이의 열교환을 일으키는 방법으로 피냉각수를 냉각한다. 이때, 피냉각수를 냉각하기 위해서 사용된 외부 공기는 고온 다습한 상태로 냉각탑에서 배출된다. 냉각탑 외부의 온도가 이슬점 이하인 경우에는 배출된 외부 공기에 포함된 수분이 응축되면서 작은 물방울이 되어 빛을 산란시켜 마치 흰 연기처럼 보이며, 이를 백연이라고 한다. 이러한 백연은 냉각탑뿐만 아니라 굴뚝이나 습식정화장치와 같이 수증기를 머금은 고온의 가스를 배출하는 구조물에서도 발생한다. 백연에 대한 법적 규제는 없으나, 인근 주민들이 화재로 오인하여 화재 신고를 하거나, 오염물질을 배출하는 것으로 오인되어 민원이 발생하는 일도 빈번하기 때문에 제거가 필요하다. There is an increasing demand for cooling towers to cool water used in large quantities in various plants, factories, buildings, and the like. The cooling tower cools the water to be cooled by injecting external air into the cooling tower by using a blower installed at an exhaust port of the upper end, and spraying the water to be cooled by using a nozzle inside the cooling tower to cause heat exchange between the water to be cooled and the outside air. do. At this time, the outside air used to cool the water to be cooled is discharged from the cooling tower in a hot and humid state. When the temperature outside the cooling tower is below the dew point, the moisture contained in the discharged outside air condenses and becomes small droplets to scatter the light and look like white smoke, which is called white lead. This white smoke is generated not only in cooling towers but also in structures that discharge hot gases containing steam, such as chimneys or wet purifiers. There is no legal regulation on white smoke, but it is necessary to remove it because frequent complaints are caused by neighboring people who are mistaken for a fire report or a pollutant discharge.
종래에는 냉각탑이나 습식정화장치의 백연을 제거하는 방법으로 피냉각수나 세정액을 가능하면 차게하여 백연을 제거하는 방법이 사용되었다. 그러나 피냉각수 전체를 냉각하는 종래의 방식은 냉각열량이 너무 많이 소요되기 때문에 비경제적이었다. Conventionally, as a method of removing white smoke from a cooling tower or a wet purifier, a method of removing white smoke by cooling the water to be cooled or the cleaning liquid as much as possible is used. However, the conventional method of cooling the whole to-be-cooled water was uneconomical because the amount of heat of cooling was too high.
굴뚝이나 습식정화장치에도 사용되는 물을 냉각하여 백연을 제거하는 방법이 사용되었으며, 상술한 문제점이 있었다. 또한, 습식정화장치의 경우에는 세정액을 냉각하기 위해 사용되는 열교환기의 금속제 냉각코일이 세정액에 의해서 부식될 수 있다는 문제도 있었다.A method of removing white lead by cooling water used in a chimney or a wet purifier has been used, which has the above-mentioned problems. In addition, in the case of the wet purifier, there is a problem that the metal cooling coil of the heat exchanger used to cool the cleaning liquid may be corroded by the cleaning liquid.
상술한 바와 같이, 종래에는 백연을 제거하기 위한 수단으로서, 습식정화장치나 냉각탑에서 사용되는 액체의 온도를 직접 낮추는 방법을 사용하였다. 그러나 피냉각수나 세정액 등의 액체의 온도를 백연이 발생하지 않는 온도까지 낮추기 위해서는 엄청난 양의 외부 공기가 유입되어야 하므로, 현실적으로 백연을 제거하는 것이 불가능하였다. As described above, conventionally, as a means for removing white smoke, a method of directly lowering the temperature of a liquid used in a wet purification apparatus or a cooling tower has been used. However, in order to lower the temperature of liquid such as water to be cooled or cleaning liquid to a temperature where white smoke does not occur, a large amount of external air must be introduced, so it was impossible to remove white lead.

도 1은 본 발명에 따른 가스 냉각 장치의 일실시예가 설치된 냉각탑을 개략적으로 나타낸 도면이다. 도 1을 참고하면, 본 발명에 따른 가스 냉각 장치의 일실시예는 가스 냉각 챔버(110)를 구비하는 가스 냉각부(100)와 냉각수 냉각 챔버(210)를 구비하는 냉각수 냉각부(200)를 포함한다. 본 실시예에 있어서, 가스 냉각 챔버(110)는 냉각탑(300)의 상부와 일체를 이룬다. 1 is a view schematically showing a cooling tower in which an embodiment of a gas cooling device according to the present invention is installed. Referring to FIG. 1, one embodiment of a gas cooling apparatus according to the present invention includes a gas cooling unit 100 having a gas cooling chamber 110 and a cooling water cooling unit 200 having a cooling water cooling chamber 210.

가스 냉각 챔버(110)는 가스가 유입되는 입구(111)와 유입된 가스가 배출되는 출구(113) 및 유입된 가스가 입구(111)에서 출구(113)를 향해 유동하는 내부공간(114)을 형성하는 측벽(112)을 포함한다. The gas cooling chamber 110 includes an inlet 111 through which gas is introduced, an outlet 113 through which the introduced gas is discharged, and an internal space 114 through which the inlet gas flows from the inlet 111 toward the outlet 113. And forming sidewalls 112.
가스는 냉각탑에서 배출된 수증기가 포함된 고온의 가스, 습식세정장치에서 배출된 가스, 굴뚝에서 배출된 고온의 가스 등일 수 있다. 본 실시예에서는 냉각탑(300)에 결합된 가스 냉각 장치를 예로 들어서 설명한다. The gas may be a high temperature gas including water vapor discharged from the cooling tower, a gas discharged from the wet cleaning device, a high temperature gas discharged from the chimney, and the like. In this embodiment, a gas cooling device coupled to the cooling tower 300 will be described as an example.
냉각탑(300)에 공급되는 외기는 가스 냉각 챔버(110)의 출구(113)에 설치된 송풍기(120)에 의해서, 아래에서 위로 공급된다. 냉각탑(300)에 공급된 외기는 냉각탑(300)에 공급되는 피냉각수(부하에 의해서 가열된 후 냉각탑에 공급된 냉각수)에 의해서 고온 다습한 상태로 가스 냉각 챔버(110)의 입구(111)로 유입된다. 냉각탑(300)의 피냉각수 분사 노즐(331)에서 분사된 피냉각수는 외기에 의해서 냉각된 후 피냉각수 저장부(336)에 저장된다. 저장된 피냉각수는 피냉각수 순환배관(334)을 통해서 피냉각수 분사 노즐(331)에 공급된다.

Outside air supplied to the cooling tower 300 to the inlet 111 of the gas cooling chamber 110 in a state of high temperature and humidity by the cooled water (cooling water supplied to the cooling tower after being heated by the load) supplied to the cooling tower 300. Inflow. The cooled water injected from the coolant spray nozzle 331 of the cooling tower 300 is cooled by the outside air and then stored in the cooled water storage unit 336. The stored coolant is supplied to the coolant spray nozzle 331 through the coolant circulation pipe 334.
종래에는 이러한 피냉각수 자체를 냉각하여 냉각탑(300)에서 배출되는 가스에 의한 백연을 제거하고자 하였으나, 본 발명에서는 수증기를 포함한 상태로 냉각탑(300)에서 배출되어 가스 냉각 챔버(110)로 유입된 가스만을 냉각하는 방법으로 백연을 제거한다. 이러한 방법으로 적은 냉각 열량으로 백연을 제거할 수 있다.Conventionally, to cool the water to be cooled itself to remove the white smoke due to the gas discharged from the cooling tower 300, in the present invention is discharged from the cooling tower 300 in the state containing water vapor introduced into the gas cooling chamber 110 The white smoke is removed by cooling the bay. In this way, white smoke can be removed with a small amount of cooling heat.
가스 냉각 챔버(110)의 내부공간(114)에는 가스를 냉각하기 위한 차가운 냉각수를 분사하는 노즐(131) 및 냉각수 안내판(133)이 설치된다. 노즐(131)은 내부공간(114)의 상부에 설치된다. 노즐(131)에서는 약 120°의 각도로 차가운 냉각수가 고르게 분사된다. 노즐(131)의 아래에는 냉각수 안내판(133)이 설치된다. 그리고 냉각수 안내판(133)의 아래에는 냉각수 저장부(132)가 설치된다. The internal space 114 of the gas cooling chamber 110 is provided with a nozzle 131 and a cooling water guide plate 133 for spraying cold cooling water for cooling the gas. The nozzle 131 is installed above the inner space 114. In the nozzle 131, cold coolant is evenly sprayed at an angle of about 120 °. The cooling water guide plate 133 is installed under the nozzle 131. The coolant storage unit 132 is installed under the coolant guide plate 133.
냉각수 안내판(133)은 가스 냉각 챔버(110)의 측벽(112)과 함께 가스(냉각탑에서 배출된 수증기가 포함된 고온의 외기)가 흐르는 경로를 형성하는 역할을 한다. 또한, 노즐(131)에서 분사된 냉각수를 냉각수 저장부(132)로 안내하는 역할을 한다. 그리고 냉각수 커튼(3)을 가스의 유동 경로 상에 형성하는 역할을 한다. 가스는 냉각수 커튼(3)을 통과하지 않고서는 출구(113)로 배출되지 않는다. 따라서 가스와 냉각수가 완벽하게 접촉되게 한다. 본 발명에서는 냉각수 안내판(133)의 수를 늘리는 방법으로 간단하게 가스와 차가운 냉각수의 접촉 빈도를 높일 수 있다. The cooling water guide plate 133 serves to form a path through which gas (hot air including hot water vapor discharged from the cooling tower) flows along the sidewalls 112 of the gas cooling chamber 110. In addition, the cooling water injected from the nozzle 131 serves to guide the cooling water storage unit 132. And it serves to form the coolant curtain (3) on the flow path of the gas. The gas is not discharged to the outlet 113 without passing through the coolant curtain 3. Thus, the gas and the coolant are brought into perfect contact. In the present invention, by increasing the number of the coolant guide plate 133, it is possible to simply increase the frequency of contact between the gas and the cold coolant.
본 실시예에 있어서, 냉각수 안내판(133)은 측벽(112)에서 내부공간(114)을 향해서 연장된다. 냉각수 안내판(133)은 냉각수를 냉각수 저장부(132)로 흘릴 수 있도록, 아래 방향으로 기울어진 상태로 연장된다. 가스가 한 쌍의 냉각수 안내판(133) 사이의 공간으로 흐를 수 있도록, 나머지 공간은 한 쌍의 냉각수 안내판(133)에 의해서 모두 막혀있다. 냉각수 안내판(133)에 부딪힌 냉각수는 냉각수 안내판(133)을 따라서 아래로 흐르고, 냉각수 안내판(133)의 끝단에서 폭포수처럼 냉각수 저장부(132)로 떨어지면서, 냉각수 안내판(133)의 끝단과 냉각수 저장부(132)의 사이에 냉각수 커튼(3)을 형성한다.In this embodiment, the coolant guide plate 133 extends from the side wall 112 toward the inner space 114. The coolant guide plate 133 extends in a downward direction to allow the coolant to flow into the coolant reservoir 132. The remaining space is all blocked by the pair of coolant guide plates 133 so that gas can flow into the space between the pair of coolant guide plates 133. The coolant that has hit the coolant guide plate 133 flows down along the coolant guide plate 133 and falls from the end of the coolant guide plate 133 to the coolant storage unit 132 like a waterfall, thereby storing the end of the coolant guide plate 133 and the coolant storage. The cooling water curtain 3 is formed between the portions 132.
본 실시예는 냉각수 저장부(132)의 냉각수를 냉각하여 노즐(131)에 공급하기 위한 냉각장치로서 냉각수 냉각 챔버(210)를 구비한다. The present embodiment includes a cooling water cooling chamber 210 as a cooling device for cooling the cooling water of the cooling water storage unit 132 and supplying the cooling water to the nozzle 131.

The cooling water cooling chamber 210 has an inlet 211 through which cold outside air for cooling the coolant is introduced, an outlet 213 through which the introduced outside air is discharged, and an inlet outside air flowing from the inlet 211 toward the outlet 213. And a side wall 212 forming an outside air flow space 214.
냉각수 냉각 챔버(210)의 외기 유동공간(214)의 상부에는, 외기 유동공간(214)에 냉각수를 분사하는 분사 노즐(231)이 설치된다. 그리고 냉각수 냉각 챔버(210)의 하부에는 분사 노즐(231)에서 분사된 냉각수를 저장하는 냉각수 재 저장부(236)가 배치된다. In the upper portion of the outside air flow space 214 of the cooling water cooling chamber 210, an injection nozzle 231 for injecting cooling water into the outside air flow space 214 is provided. A coolant restoring unit 236 for storing the coolant injected from the spray nozzle 231 is disposed below the coolant cooling chamber 210.
또한, 냉각수 저장부(132)에 저장된, 수증기가 포함된 고온의 가스와 접촉하여 온도가 약간 상승한 냉각수를 냉각수 재 저장부(236)에 전달하는 드레인 배관(150)과, 냉각수 재 저장부(236)에 저장된 냉각수를 노즐(131)에 공급하도록, 냉각수 재 저장부(236)와 노즐(131)을 연결하는 순환배관(134) 및 순환배관(134)에 설치되는 순환펌프(135)를 포함한다.In addition, the drain pipe 150 and the coolant re-storage unit 236 for transmitting the coolant having a slightly elevated temperature in contact with the hot gas containing water vapor stored in the coolant storage unit 132 to the coolant re-storage unit 236. Circulating pipe 134 connecting the coolant restoring unit 236 and the nozzle 131 and a circulating pump 135 installed in the circulating pipe 134 so as to supply the coolant stored in the nozzle 131. .
또한, 냉각수 재 저장부(236)에 저장된 온도가 약간 상승한 냉각수를 분사 노즐(231)에 공급하도록, 냉각수 재 저장부(236)와 분사 노즐(231)을 연결하는 연결배관(234) 및 연결배관(234)에 설치되는 펌프(245)를 포함한다. 분사노즐(231)에서 공급된 냉각수는 냉각 챔버(210)에 유입된 차가운 외기와 접촉하여 차갑게 냉각된다. In addition, the connecting pipe 234 and the connecting pipe connecting the coolant reserving unit 236 and the spray nozzle 231 to supply the coolant having a slightly increased temperature stored in the coolant reserving unit 236 to the injection nozzle 231. And a pump 245 installed at 234. The cooling water supplied from the injection nozzle 231 is cooled in contact with the cold outside air introduced into the cooling chamber 210.
본 발명에 있어서, 송풍기(220)에 의해서 공급된 찬 외기와 접촉하여 냉각된 차가운 냉각수는 가스 냉각 챔버(110) 내부의 노즐(131)에서 분사되어 냉각탑(300)에서 온도가 상승된 고온 다습한 가스와 접촉한다. 가스와 접촉하여 온도가 약간 상승한 냉각수는 냉각수 냉각 챔버(210)에 회수된다. 즉, 냉각수는 피냉각수 저장부(336)에 저장되는 것이 아니라 냉각수 재 저장부(236)에 저장된다. 냉각수는 피냉각수 저장부(336)의 상대적으로 고온의 피냉각수와 혼합되지 않는다. In the present invention, the cold coolant cooled in contact with the cold outside air supplied by the blower 220 is sprayed from the nozzle 131 inside the gas cooling chamber 110, the high temperature and high humidity of the temperature rise in the cooling tower 300 Contact with gas. Cooling water whose temperature slightly rises in contact with the gas is recovered to the cooling water cooling chamber 210. That is, the coolant is not stored in the water to be cooled 336 but in the coolant reserving unit 236. The coolant is not mixed with the relatively hot coolant in the coolant reservoir 336.
냉각수 냉각 챔버(210)에서 공급된 차가운 냉각수는 피 냉각수 저장부(336)와 혼합되지 않고, 가스와의 열교환으로 온도가 약간 상승한 상태에서 다시 냉각수 냉각 챔버(210)에서 냉각된다. The cold cooling water supplied from the cooling water cooling chamber 210 is not mixed with the cooling water storage unit 336, and is cooled again in the cooling water cooling chamber 210 in a state where the temperature is slightly increased by heat exchange with gas.
종래에는 피냉각수 자체를 냉각하여 백연을 제거하고자 하였으나, 본 발명에서는 냉각탑(300) 상부의 수증기가 포함된 고온의 가스만 냉각수 냉각 챔버(210)에서 찬 외기에 의해 차게 냉각된 냉각수로 냉각시킨다. 고온의 가스와 접촉되어 회수된 온도가 약간만 상승한 냉각수를 적은 냉각열량의 냉각수 냉각 챔버(210)로 냉각하기 때문에 적은 냉각열량으로도 냉각탑(300) 상부에서 발생하는 백연을 효과적으로 제거할 수 있다.Conventionally, to cool off the water to be cooled itself to remove the white smoke, in the present invention, only the hot gas containing the steam of the upper portion of the cooling tower 300 is cooled by the coolant cooled by cold outside air in the cooling water cooling chamber 210. Since the coolant having a slight increase in temperature recovered by contacting the hot gas is cooled by the coolant cooling chamber 210 having a small amount of cooling heat, white smoke generated in the upper part of the cooling tower 300 may be effectively removed even with a small amount of cooling heat.
이하에서는 본 실시예에 따른 가스 냉각 장치의 작용에 대해서 설명한다. Hereinafter, the operation of the gas cooling device according to the present embodiment will be described.
기계장치 등의 부하에 의해서 가열된 피냉각수는 냉각탑(300)의 피냉각수 저장부(336)에 저장된다. 저장된 피냉각수는 피냉각수 분사 노즐(331)에서 분사되고, 냉각탑(300)에 유입된 외기에 의해서 32℃ 정도로 냉각된다. 이 과정에서 냉각탑(300)에 유입된 외기는 고온 다습한 상태가 된다. 이러한 수증기를 포함한 가스가 냉각탑(300)의 외부로 바로 배출되면 수증기가 응결되면서 물방울이 되어 백연이 발생한다. The cooled water heated by a load such as a mechanical device is stored in the cooled water storage unit 336 of the cooling tower 300. The stored coolant is sprayed from the coolant spray nozzle 331 and cooled to about 32 ° C. by outside air introduced into the cooling tower 300. In the process, the outside air introduced into the cooling tower 300 is in a high temperature and high humidity. When the gas including the water vapor is discharged directly to the outside of the cooling tower 300, water vapor is condensed to form water droplets.
본 발명에서는 냉각탑(300)에서 배출된 수증기를 포함한 고온의 가스가 냉각탑(300)의 상부에 일체로 결합된 가스 냉각 챔버(110)에 유입된다. 이 가스는 가스 냉각 챔버(110)의 내부 공간(114)에 형성된 냉각수 커튼(3)을 통과하면서 18℃ 미만으로 냉각되고, 가스 냉각 챔버(110)의 외부로 배출된다. 가스의 온도가 냉각수 커튼(3)을 통과하는 과정에서 충분히 낮아졌기 때문에 이 가스가 외부로 배출되어도 백연이 발생하지 않는다. 가스를 냉각하는 과정에서 온도가 약간 상승한 냉각수는 냉각수 저장부(132)에 일차로 저장되고, 드레인 배관(150)을 통해서 냉각수 냉각 챔버(210)의 냉각수 재 저장부(236)로 전달된다. 냉각수 재 저장부(236)에 저장된 냉각수는 냉각수 재 저장부(236)와 분사 노즐(231)을 연결하는 연결배관(234)을 따라서 분사 노즐(231)에 공급되고, 분사 노즐(231)에서 분사된 냉각수는 냉각수 냉각 챔버(210)에 유입되는 차가운 외기에 의해서 냉각된다. 차갑게 냉각된 냉각수는 냉각수 재 저장부(236)에 저장되고, 냉각수 재 저장부(236)와 노즐(131)을 연결하는 순환배관(134)을 따라서 노즐(131)에 공급된다. In the present invention, the hot gas including the water vapor discharged from the cooling tower 300 flows into the gas cooling chamber 110 integrally coupled to the upper portion of the cooling tower 300. The gas is cooled to less than 18 ° C. while passing through the cooling water curtain 3 formed in the internal space 114 of the gas cooling chamber 110, and discharged to the outside of the gas cooling chamber 110. Since the temperature of the gas is sufficiently low in the course of passing through the cooling water curtain 3, white smoke does not occur even when this gas is discharged to the outside. The cooling water whose temperature slightly rises in the course of cooling the gas is primarily stored in the cooling water storage unit 132 and is transferred to the cooling water reserving unit 236 of the cooling water cooling chamber 210 through the drain pipe 150. The coolant stored in the coolant reserving unit 236 is supplied to the spray nozzle 231 along a connecting pipe 234 connecting the coolant reserving unit 236 and the spray nozzle 231, and sprayed from the spray nozzle 231. The cooled coolant is cooled by cold outside air introduced into the coolant cooling chamber 210. The coolant coolant is stored in the coolant reserving unit 236 and is supplied to the nozzle 131 along the circulation pipe 134 connecting the coolant reserving unit 236 and the nozzle 131.
본 발명에서는 냉각탑(300)의 피냉각수가 아닌, 가스 냉각 챔버(110)로 유입된 수증기를 포함한 고온의 가스만을 냉각수 냉각 챔버(210)에서 냉각된 차가운 냉각수를 이용해서 냉각하므로 적은 냉각 열량으로 백연을 제거할 수 있다. In the present invention, only the hot gas including the water vapor introduced into the gas cooling chamber 110, not the water to be cooled in the cooling tower 300, is cooled using the cold cooling water cooled in the cooling water cooling chamber 210. Can be removed.
즉, 종래에는 냉각탑(300)에서 외기를 이용하여 피냉각수 전체를 냉각하여 백연을 제거하고자 하였으나, 본 발명에서는 냉각탑(300) 상부의 수증기를 포함한 고온의 가스만 별도의 차가운 냉각수를 이용하여 냉각하고, 이 과정에서 온도가 약간 상승한 냉각수만 냉각수 냉각 챔버(210)에서 냉각하므로, 적은 냉각 열량으로 효과적으로 백연을 제거할 수 있다. That is, in the related art, the cooling tower 300 is intended to remove white smoke by cooling the entire cooled water using external air, but in the present invention, only a high temperature gas including water vapor in the upper portion of the cooling tower 300 is cooled using a separate cold cooling water. In this process, only the cooling water having a slightly increased temperature is cooled in the cooling water cooling chamber 210, so that white smoke can be effectively removed with a small amount of cooling heat.
도 2 내지 10은 본 발명에 따른 다른 실시예들의 가스 냉각 챔버 내부의 구조를 나타낸 도면들이다. 2 to 10 are views showing the structure of the gas cooling chamber of another embodiment according to the present invention.
도 2에 도시된 바와 같이, 본 실시예에 있어서, 냉각수 저장부(132)는 도면상 좌측과 우측에 각각 하나씩 설치된다. 이에 따라서 냉각수 안내판(133)의 구성이 변경된다. As shown in FIG. 2, in the present embodiment, one coolant storage unit 132 is provided at each of left and right sides of the drawing. Accordingly, the configuration of the coolant guide plate 133 is changed.
냉각수 안내판(133)은 제1냉각수 안내판(133a)과, 한 쌍의 제2냉각수 안내판(133b)을 포함한다. The coolant guide plate 133 includes a first coolant guide plate 133a and a pair of second coolant guide plates 133b.
제1냉각수 안내판(133a)은 도면상 좌측과 우측의 냉각수 저장부(132)에 냉각수를 흘릴 수 있도록, 양쪽 끝단으로 갈수록 높이가 낮아지도록 경사져있다. The first coolant guide plate 133a is inclined so that the height is lowered toward both ends so that the coolant can flow to the coolant reservoirs 132 on the left and right sides of the drawing.
한 쌍의 제2냉각수 안내판(133b)은 제1냉각수 안내판(133a)과 노즐(131) 사이에 설치되며, 노즐(131)에서 분사된 냉각수를 안내하여 제1냉각수 안내판(133a) 위에 떨어뜨린다. 한 쌍의 제2냉각수 안내판(133b)은 서로 마주보는 측벽(112)으로부터 내부공간(114)의 중심을 향하여 연장된다. 한 쌍의 제2냉각수 안내판(133b)을 따라서 흐른 냉각수는 제1냉각수 안내판(133a) 위로 떨어지면서, 냉각수 커튼(3)을 형성한다. The pair of second coolant guide plates 133b are installed between the first coolant guide plates 133a and the nozzles 131 and guide the coolant sprayed from the nozzles 131 and drop them on the first coolant guide plates 133a. The pair of second coolant guide plates 133b extend from the side walls 112 facing each other toward the center of the internal space 114. The coolant flowing along the pair of second coolant guide plates 133b falls on the first coolant guide plate 133a and forms the coolant curtain 3.
도면상 아래 방향에서 유입된 수증기를 포함하는 고온의 가스는 제1냉각수 안내판(133a)과 냉각수 저장부(132) 사이에 형성된 냉각수 커튼(3)과 제2냉각수 안내판(133b)과 제1냉각수 안내판(133a) 사이에 형성된 냉각수 커튼(3)을 통과한 후 출구가 형성된 윗 방향으로 흐른다. 필요한 경우에는 냉각수 안내판(133b) 위에 제1냉각수 안내판(133a)과 동일한 형상의 제3냉각수 안내판을 설치할 수 있으며, 그 위에도 냉각수 안내판들을 설치할 수 있다. The high temperature gas including the water vapor introduced from the downward direction in the drawing is the coolant curtain 3 and the second coolant guide plate 133b and the first coolant guide plate formed between the first coolant guide plate 133a and the coolant storage unit 132. After passing through the coolant curtain 3 formed between 133a, the outlet flows upward. If necessary, a third coolant guide plate having the same shape as the first coolant guide plate 133a may be installed on the coolant guide plate 133b, and the coolant guide plates may be installed thereon.
또한, 제1냉각수 안내판(133a)과 제2냉각수 안내판(133b)의 위치를 서로 바꿔 설치하고, 냉각수 저장부(132)를 내부공간(114)의 하부 중심에 하나만 설치할 수도 있다.In addition, the positions of the first coolant guide plate 133a and the second coolant guide plate 133b may be interchanged with each other, and only one coolant storage unit 132 may be installed in the lower center of the inner space 114.
도 3에 도시된 바와 같이, 높이 차이를 두고 서로 마주보는 측벽(112)으로부터 연장된 냉각수 안내판(133)들을 이용하여 냉각수 커튼(3)들을 형성하면서, 냉각수를 냉각수 저장부(132)로 안내할 수도 있다. As shown in FIG. 3, the coolant may be guided to the coolant reservoir 132 while forming the coolant curtains 3 using the coolant guide plates 133 extending from the sidewalls 112 facing each other at a height difference. It may be.
도 4에 도시된 실시예는 도 3에 도시된 실시예와 달리 냉각수 안내판(133)들의 끝 부분(137)이 아래 방향으로 둥글게 말려져 있다. 말려진 끝 부분(137)은 코안다 효과(Coanda effect)를 이용하여 냉각수 안내판(133)에서 떨어지는 냉각수의 방향을 변경하는 역할을 한다. 냉각수 안내판(133)에서 떨어지는 냉각수는 코안다 효과에 의해서 냉각수 안내판(133)의 말려진 끝 부분(137)의 곡면을 따라서 흐르게 된다. 그 결과 냉각수가 사선으로 냉각수 안내판(133)에서 떨어지게 된다. 냉각수가 사선으로 떨어지면, 냉각수 커튼(3)의 면적이 그만큼 더 커지게 되어 세정효율이 향상된다. In the embodiment shown in FIG. 4, unlike the embodiment shown in FIG. 3, the end portions 137 of the coolant guide plates 133 are rounded downward. The rolled end portion 137 serves to change the direction of the coolant falling from the coolant guide plate 133 by using a Coanda effect. The coolant falling from the coolant guide plate 133 flows along the curved surface of the curled end portion 137 of the coolant guide plate 133 by the Coanda effect. As a result, the coolant is dropped from the coolant guide plate 133 diagonally. When the coolant falls diagonally, the area of the coolant curtain 3 becomes larger so that the cleaning efficiency is improved.
또한, 냉각수 저장부(132)에는 냉각수가 넘치는 것을 방지하기 위해서 배플 플레이트(140)가 설치되어 있다. In addition, the cooling water storage unit 132 is provided with a baffle plate 140 to prevent the cooling water from overflowing.

Also in the embodiment shown in FIG. 5, the coolant falling from the coolant guide plate 133 falls diagonally due to the Coanda effect as in the embodiment shown in FIG. 4. In this embodiment, the end portion 138 of the coolant guide plate 133 is rolled up, so that the coolant stored in the space surrounded by the coolant guide plate 133 and the side wall 112 is the end portion 138 of the coolant guide plate 133. Falling down over to form a coolant curtain (3).
도 6에 도시된 실시예에서는 냉각수 안내판(133)의 끝 부분 아래에 원형 단면을 가진 냉각수 안내바(139)가 설치되어 있으며, 냉각수 안내판(133)에서 떨어진 냉각수는 코안다 효과에 의해서 냉각수 안내바(139)의 표면을 따라서 흐르고, 사선으로 떨어지면서 냉각수 커튼(3)을 형성한다.In the embodiment shown in FIG. 6, a coolant guide bar 139 having a circular cross section is installed below the end of the coolant guide plate 133, and the coolant dropped from the coolant guide plate 133 is cooled by the Coanda effect. It flows along the surface of 139 and falls diagonally to form the coolant curtain 3.
도 7에 도시된 실시예는 내부공간(114)의 폭이 넓은 경우에 복수의 노즐(131)에서 분사되는 냉각수를 안내하기 위해 냉각수 안내판(133)을 구성하는 방법을 나타낸다. 도 7에 도시된 바와 같이, 내부공간(114)의 폭 방향으로, 측벽(112)에서 아래 방향으로 경사진 상태로 연장된 제3냉각수 안내판(133c)들과 서로 반대 방향으로 연장된 한 쌍의 경사면을 구비한 제4냉각수 안내판(133d)들을 적절히 배치하여, 외기가 흐르는 경로를 형성하고, 냉각수가 외기의 경로 상에 냉각수 커튼(3)을 형성하면서 냉각수 저장부(132)로 안내되도록 할 수 있다. 7 illustrates a method of configuring the coolant guide plate 133 to guide the coolant sprayed from the plurality of nozzles 131 when the inner space 114 is wide. As shown in FIG. 7, a pair of third coolant guide plates 133c extending in an inclined direction downward from the side wall 112 in the width direction of the inner space 114 and a pair extending in opposite directions to each other. The fourth coolant guide plates 133d having the inclined surface may be properly disposed to form a path through which the outside air flows, and allow the coolant to be guided to the coolant storage unit 132 while forming the coolant curtain 3 on the path of the outside air. have.

The first coolant guide plate 133a has the same structure as that of FIG. 2. In this embodiment, the coolant rotates in the second coolant guide plate 133g and falls, so that the gas containing water vapor and the coolant are more in contact with each other.

In the embodiment shown in FIG. 10, a curved guide vane 142 is installed on the second coolant guide plate 133h to allow the coolant to rotate on the second coolant guide plate 133h. The first coolant guide plate 133a has the same structure as that of FIG. 2. In this embodiment, the cooling water is dropped along the guide vane 142 in the second cooling water guide plate 133h so that the gas containing water vapor and the cooling water are more in contact with each other.

The coolant guide plate 233 and the coolant reservoir 232 are disposed to form 2). And an eliminator 260 was installed on the injection nozzle 231. In addition, the cooling tower 300 was also configured in such a way that the coolant curtain 1 can be formed.
도 12는 본 발명에 따른 가스 냉각 장치의 또 다른 실시예가 설치된 습식정화장치를 개략적으로 나타낸 도면이다. 본 실시에의 습식정화장치(500)는 가스가 가로 방향으로 흐르도록 배치된다. 12 is a view schematically showing a wet purification apparatus in which another embodiment of a gas cooling apparatus according to the present invention is installed. The wet purification apparatus 500 of this embodiment is arrange | positioned so that gas may flow in a horizontal direction.
도 12를 참고하면, 습식정화장치(500)의 세정 노즐(531)에서 분사된 세정액은 고온의 배기가스와 접촉된다. 습식정화장치(500) 하류 측으로 배출된 수증기를 포함하는 고온의 가스는 습식정화장치(500)의 후단과 연결된 가스 냉각 챔버(410)에 유입된다. 가스 냉각 챔버(410)의 내부공간(414)에는 냉각수 냉각 챔버(210)에서 18℃미만으로 차갑게 냉각된 냉각수가 노즐(431)을 통해서 분사된다. 냉각수는 수증기를 포함하는 가스와 접촉하게 하여 가스 중의 수증기가 냉각되면서 응축되어 냉각수와 합쳐져서 가스 냉각 챔버(410)의 엘리미네이터(460)에서 제거된다. 냉각된 가스는 냉각수 냉각 챔버(210)의 외부로 배출되고 냉각수는 엘리미네이터(460) 하부의 냉각수 저장부(432)에 모인다. 냉각수 저장부(432)에 모인 냉각수는 드레인 배관(450)을 통해 냉각수 냉각 챔버(210)의 냉각수 재 저장부(236)로 배출된다. 그리고 이 냉각수는 냉각수 냉각 챔버(210)에서 냉각된 후 다시 가스 냉각 챔버(410) 내의 노즐(431)을 통해서 분사된다. Referring to FIG. 12, the cleaning liquid injected from the cleaning nozzle 531 of the wet purification apparatus 500 is in contact with the high temperature exhaust gas. The hot gas including the water vapor discharged downstream of the wet purifier 500 is introduced into the gas cooling chamber 410 connected to the rear end of the wet purifier 500. In the internal space 414 of the gas cooling chamber 410, coolant cooled to less than 18 ° C. in the cooling water cooling chamber 210 is injected through the nozzle 431. The coolant is brought into contact with the gas including water vapor, condenses as the water vapor in the gas cools, merges with the coolant, and is removed from the eliminator 460 of the gas cooling chamber 410. The cooled gas is discharged to the outside of the cooling water cooling chamber 210 and the cooling water is collected in the cooling water storage unit 432 under the eliminator 460. The coolant collected in the coolant storage 432 is discharged to the coolant reserving unit 236 of the coolant cooling chamber 210 through the drain pipe 450. The coolant is cooled in the coolant cooling chamber 210 and then injected again through the nozzle 431 in the gas cooling chamber 410.
또한, 별도의 냉각수 저장부(432) 없이 드레인 배관(450)을 통해서 바로 배출되도록 할 수도 있다. In addition, it may be directly discharged through the drain pipe 450 without a separate coolant storage unit 432.
도 13은 본 발명에 따른 가스 냉각 장치의 또 다른 실시예가 설치된 악취발생부를 개략적으로 나타낸 도면이다. 본 실시예에서는 고온의 가스를 냉각하기 위해서 악취발생부(700)의 상부에 가스 냉각 챔버(110)를 설치한다. 고온의 가스에 냉각수를 분사시켜 냉각시키면, 악취를 줄일 수 있다.13 is a view schematically showing a malodor generating unit provided with another embodiment of a gas cooling device according to the present invention. In this embodiment, in order to cool the hot gas, the gas cooling chamber 110 is installed above the odor generating unit 700. Cooling by injecting cooling water into the hot gas can reduce odor.
악취가 있는 고온의 가스를 냉각시키는 냉각수를 상술한 냉각수 냉각 챔버를 이용하여 냉각하면 악취가 냉각수 냉각 챔버의 출구를 통해서 외부로 배출될 수 있다. 따라서 냉각수 냉각 챔버 대신에 금속 냉각코일(610)을 설치하여 냉각코일(610) 내부로 냉각수를 공급하고 냉각코일(610) 외부의 송풍기(620)로 외기를 냉각코일(610)에 접촉시켜 냉각코일(610) 내부의 냉각수를 차갑게 냉각한다. 냉각효율을 높이기 위하여 냉각코일(610) 외부에 냉각핀(611)을 설치할 수 있다. 냉각코일(610)이 밀폐형이므로 냉각수의 악취가 외부로 배출되지 않는다.When the cooling water for cooling the malodorous hot gas is cooled by using the aforementioned cooling water cooling chamber, the odor may be discharged to the outside through the outlet of the cooling water cooling chamber. Therefore, a metal cooling coil 610 is installed in place of the cooling water cooling chamber to supply the cooling water into the cooling coil 610 and to blow the outside air into the cooling coil 610 by the blower 620 outside the cooling coil 610 to cool the cooling coil. 610 cools the coolant inside. In order to increase the cooling efficiency, the cooling fins 611 may be installed outside the cooling coil 610. Since the cooling coil 610 is hermetically sealed, the odor of the cooling water is not discharged to the outside.

In the present embodiment, unlike FIG. 13, the cooling water is indirectly cooled by using the heat exchanger 670. When the odor generating unit 700 and the heat exchanger 670 are stopped in winter, the cooling water remaining in the cooling coil 610 freezes and the cooling coil 610 is damaged. The water is circulated, and the cooling water of the gas cooling chamber 110 is cooled by heat exchange with the antifreeze cooled by the outside air through the heat exchanger 670.
