본 발명은 발전소 및 고속, 대유량 배기가스 배출용 덕트 내 입자상 탈황제의 혼합효율 향상을 위한 혼합장치에 관한 것으로,The present invention relates to a power plant and a mixing device for improving the mixing efficiency of the particulate desulfurization agent in the duct for high-speed, large-flow exhaust gas discharge,

더욱 상세하게는 화력 발전소 및 고속, 대용량 배기가스 배출장치를 운용하는 설비로부터 발생하는 배기가스에 입자상의 흡착제를 효율적으로 분산시키기 위해 접촉시간 및 반응영역을 증대시키도록 하는 입자상 탈황제의 혼합효율 향상을 위한 혼합장치에 관한 것이다.More specifically, to improve the mixing efficiency of particulate desulfurization agents to increase the contact time and reaction area in order to efficiently disperse particulate adsorbents in exhaust gases generated from thermal power plants and facilities operating high-speed, large-capacity exhaust gas dischargers. It relates to a mixing device for.

종래 화력 발전소 및 고속, 대유량 배기가스를 발생하는 배출용 덕트는 운전중 발생하는 배기가스를 배출하기 위해서 보일러에 송풍횐을 설치하고 후단에 다수의 덕트(Duct)를 통하여 전기 집진기로 보내어 분진을 제거하고 다시 탈황설비 등을 거쳐서 연도를 통하여 대기중으로 배출하게 된다.Conventional thermal power plants and exhaust ducts for generating high speed and high flow rate exhaust gas are installed in a boiler to blow exhaust gas generated during operation, and dust is sent to the electric dust collector through a plurality of ducts in the rear stage. It is removed and discharged to the atmosphere through the year again through desulfurization facilities.

그런데 이 과정에서 덕트의 한 부분에는 가이드 베인을 설치하여 배풍이 덕트의 전체 면에 골고루 이루어질 수 있도록 하는 장점이 있지만, 상기 가이드 베인에 연소가스에 포함된 플라이애쉬(Fly Ash)등의 퇴적 및 침착이 발생하여 발전설비의 정상적인 운전에 막대한 지장을 초래하게 된다.However, in this process, there is an advantage in that the guide vane is installed in one part of the duct so that the exhaust air is uniformly formed on the entire surface of the duct, but the deposition and deposition of fly ash, etc. contained in the combustion gas in the guide vane. This will cause a huge obstacle to the normal operation of the power plant.

또한, 가이드 베인의 전반부에 설치한 분사기를 통하여 물 100mℓ에 중탄산나트륨 20g을 혼합하여 안개분사를 시켜 집진기에서 이물질의 집진, 특히 SO2 가스 의 제거가 용이하도록 흡착제를 분사한다.In addition, 20 g of sodium bicarbonate is mixed with 100 ml of water through an injector installed in the first half of the guide vane to spray mist, thereby adsorbing the adsorbent to facilitate the collection of foreign matter, particularly SO 2 gas, from the dust collector.

그러나 대유량의 배기가스를 처리하기 위해서는 액체상으로 이용되는 중탄산나트륨의 경우, 고가이므로 특수한 경우를 제외하고는 입자상의 칼슘계열의 흡착제에 비해 경제성이 떨어진다.However, sodium bicarbonate, which is used in the liquid phase in order to treat a large flow rate of exhaust gas, is expensive, and is economically inferior to particulate calcium-based adsorbents except in special cases.

또한, 입자상의 흡착제를 액체상의 흡착제와 같은 방식으로 분사하기 위해 매트릭스 상의 이상류(two phase flow) 노즐을 설치하여 정확히 제어하는 것은 설치비용뿐만 아니라 부수적인 여러 가지 어려움이 따른다.In addition, precisely controlling the installation of two phase flow nozzles in the matrix to spray particulate adsorbents in the same manner as liquid adsorbents presents a number of additional difficulties as well as installation costs.

흡착제를 고속의 공기에 동반시켜 노즐을 통해 분사시키는 경우, 저속, 소유량의 덕트 내에서는 노즐로부터 분사되는 흡착제가 배기가스와 이루는 분사각도, 노즐 팁의 형상을 적절히 개량하여 노즐로부터 분사되는 흡착제의 환산각도 등을 조절하여 일정 정도 이상의 혼합 효율을 달성할 수 있으나, 고속, 대유량의 시설에는 혼합효율이 극단적으로 감소하는 단점이 있었다.When the adsorbent is entrained with high-speed air and sprayed through the nozzle, the injection angle of the adsorbent injected from the nozzle with the exhaust gas and the shape of the nozzle tip are appropriately improved in the low-speed, low-flow duct to convert the adsorbent injected from the nozzle. By adjusting the angle and the like to achieve more than a certain degree of mixing efficiency, there was a disadvantage that the mixing efficiency is extremely reduced in high-speed, large flow rate facilities.

본 발명은 이러한 종래의 결점을 해소하기 위하여 안출된 것으로, 덕트 내를 고속으로 유동하는 대유량 배기가스와 흡착제의 혼합을 촉진시켜 배기가스와 흡착제의 접촉시간 및 반응영역을 증대시키도록 함을 목적으로 한다.The present invention has been made to solve the above-mentioned drawbacks, and aims to increase the contact time and reaction region of the exhaust gas and the adsorbent by promoting the mixing of the large flow exhaust gas and the adsorbent flowing in the duct at high speed. It is done.

본 발명은 혼합을 위한 여러 가지 분사방식의 변화, 또는 대규모 덕트 내부 유로개선 등에 비해 경제성 가이드 베인의 설치가 용이하도록 함을 목적으로 한다.It is an object of the present invention to facilitate the installation of economic guide vanes compared to various injection methods for mixing, or to improve the flow path inside a large duct.

In addition, the side guide vanes 16 are installed on both sides to create a velocity component perpendicular to the flow direction of the exhaust gas and the injected adsorbent so that the central axis of rotation generates the same swirl flow as the flow direction.

상기 가이드 베인(14, 15, 16)은 덕트(13)에 고정하는 고정면(20)의 한 부분에서 수직으로 돌출하는 높이(h)를 갖고 고정면(20)의 선단과 높이(h)의 선단을 경사지게 연결하는 길이(s)를 갖도록 한다.The guide vanes 14, 15, and 16 have a height h protruding vertically from a portion of the fixing surface 20 fixed to the duct 13, and the guide vanes 14, 15, 16 have a height and height h of the fixing surface 20. It is to have a length (s) connecting the tip inclined.

상기 가이드 베인(14, 15, 16)은 전체적으로 삼각형 형상으로 성형하되, 흐름 방향으로 길이(s)와 흐름에 수직인 방향으로의 높이(h) 비를 2:1 이상으로 하여 가이드 베인(14, 15, 16) 뒷부분에 형성되는 후류 영역을 최소한으로 하는 것이 바람직하다.The guide vanes 14, 15, and 16 are formed in a triangular shape as a whole, but the guide vanes 14, with the length h in the flow direction and the height h in the direction perpendicular to the flow, be 2: 1 or more. 15, 16) It is desirable to minimize the wake region formed behind.

상기 측면 가이드 베인(16)의 우측에는 혼합가스 유출구(17)를 두어 대유량의 배기가스에 입자상의 흡착제를 효율적으로 분산시키기 위해 혼합을 촉진하는 것 이다.The right side of the side guide vane 16 is provided with a mixed gas outlet 17 to promote mixing to efficiently disperse the particulate adsorbent in a large flow rate exhaust gas.

이러한 구성으로 이루어진 본 발명은, 덕트(13)의 왼쪽에 있는 배기가스 유입구(10)를 통하여 고속, 대유량의 배기가스가 유입된다.According to the present invention having such a configuration, the high speed and large flow rate of exhaust gas flows in through the exhaust gas inlet port 10 on the left side of the duct 13.

고속, 대유량의 배기가스가 유입되어 덕트(13) 내를 통과할 때 흡착제 유입라인(11)을 통하여 공급하는 입자상의 흡착제가 상, 하측에 각각 일정한 간격을 두고 설치한 6개의 흡착제 유입구(12)에서 분사한다.Six adsorbent inlets (12) provided with particulates adsorbed through the adsorbent inlet line (11) at regular intervals at the upper and lower sides when the high-speed, large-flow exhaust gas flows through the duct (13). Spray on).

입자상의 흡착제가 분사되면서 흡착제와 유입되는 배기가스는 상부 가이드 베인(14)과 하부 가이드 베인(15) 및 측면 가이드 베인(16)을 통하여 흐름 방향과 수직인 속도성분을 만들어 회전의 중심축이 흐름 방향과 동일한 선회류를 발생시키며 혼합이 이루어진다.As the particulate adsorbent is injected, the adsorbent and the incoming exhaust gas make the velocity component perpendicular to the flow direction through the upper guide vane 14, the lower guide vane 15, and the side guide vane 16, and the central axis of rotation flows. The mixing takes place with the same swirl flow as the direction.

가이드 베인(14, 15, 16)은 고정면(20)이 덕트(13)에 부착되어 고정하는 면으로 하고, 흐름 방향으로 길이(s)가 돌출되도록 배열하되, 흐름 방향으로의 길이(s)와 흐름에 수직인 방향으로의 높이(h)의 비를 도 5와 같이 2:1 이상으로 하여 가이드 베인(14, 15, 16) 뒷부분에 형성되는 후류 영역을 최소화하였다.The guide vanes 14, 15, and 16 are fixed surfaces 20 attached to the duct 13 to be fixed, and are arranged such that the length s protrudes in the flow direction, but the length s in the flow direction. The ratio of the height h in the direction perpendicular to the vortex flow was 2: 1 or more as shown in FIG. 5 to minimize the wake region formed behind the guide vanes 14, 15, and 16.

상기 흡착제 유입구(12)인 분사노즐에서만 흡착제를 덕트(13)내에 투입시켰을 경우, 덕트(13) 내 강한 고속기류의 영향으로 흡착제의 분산은 거의 일어나지 않는 반면, 다수의 가이드 베인(14, 15, 16)에 의해 다소의 압력손실이 발생하나, 가장 후반부에 위치한 측면 가이드 베인(16)에서 흐름 방향으로 단면을 잘랐을 때, 전체 유로 단면의 2/3 이상에 흡착제가 분산되는 것을 확인하였으며, 혼합가스 유 출구(17) 쪽으로 갈수록 분산의 영향이 커진다.When the adsorbent is introduced into the duct 13 only in the injection nozzle which is the adsorbent inlet 12, the dispersion of the adsorbent hardly occurs due to the influence of the strong high speed air in the duct 13, whereas the plurality of guide vanes 14, 15, 16) Some pressure loss occurs, but when the cross section is cut in the flow direction at the side guide vane 16 located in the latter half, it is confirmed that the adsorbent is dispersed in at least two thirds of the cross section of the entire flow path. Towards the oil outlet 17 the effect of dispersion is greater.
