Description
본 고안은 전자선 가속기의 배가스냉각장치에 관한 것으로, 특히 본 고안은 냉각장치가 2단 냉각구조를 갖는 것에 관한 것이다.The present invention relates to an exhaust gas cooling device of an electron beam accelerator, and in particular, the present invention relates to a cooling device having a two-stage cooling structure.
첨부 도면중 도 1a는 종래 병류식 1단 냉각장치를 나타낸다.1A of the accompanying drawings shows a conventional co-current type single stage cooling device.
이 냉각기(110)는 배가스입구부(112)가 상단에 형성되고 이로부터 공급된 배가스가 냉각기(110)의 내부 상단에 설치된 워터스프레이(114)를 통하여 냉각이 이루어지고 냉각후의 냉각수는 하단배수구(116)를 통하여 배수되고, 배가스는 전자선 반응기(도시생략)에 공급되도록 냉각기(110)의 측면에 연결된 배가스출구(118)를 통하여 배출된다.The cooler 110 has an exhaust gas inlet 112 formed at the upper end and the exhaust gas supplied therefrom is cooled through the water spray 114 installed at the inner upper end of the cooler 110. Drained through 116, the exhaust gas is discharged through the exhaust gas outlet 118 connected to the side of the cooler 110 to be supplied to the electron beam reactor (not shown).
첨부 도면중 도 1b는 종래 향류식 1단 냉각장치를 나타낸다.Figure 1b of the accompanying drawings shows a conventional countercurrent type 1 stage cooling apparatus.
이 냉각기(120)는 배가스입구부(122)를 일측하방에 설치하고, 배가스출구부(128)는 타측 상방에 설치하며, 그 내부에는 2단의 워터스프레이(124)(126)와, 배수구(123)를 구비하여서 된다.The cooler 120 installs the exhaust gas inlet 122 at one side and the exhaust gas outlet 128 is installed at the other side. The cooler 120 includes two stages of water sprays 124 and 126 and a drain hole ( 123).
상기한 냉각기들은 냉각설비중 가장 일반화된 워터스프레이타입 냉각설비이다. 이것들은 배가스의 유동방향과 분무하는 물의 흐름방향에 따라 상기한 전자의 경우와 같은 병류식과, 향류식으로 구분하며, 실제적용시에는 골고루 적용하며, 선정기준은 증발효율에 의하여 선정한다.The above-mentioned coolers are the most common water spray type cooling facilities among the cooling facilities. These are categorized into cocurrent and countercurrent types as in the former case according to the flow direction of the flue gas and the flow direction of the sprayed water, and are applied evenly in actual application, and the selection criteria are selected by the evaporation efficiency.
상기한 냉각장치들은 고온의 배가스를 흘러가는 도중에 물을 분무하므로써 배가스의 온도를 강제 냉각시킨다. 이때 분무하는 물의 물방울 입자의 직경은 작을수록 증발효율이 좋고, 증발시간도 단축된다. 높은 증발효율을 갖기 위해서는 일반적으로 분무하는 분출구의 수압이 약 10-30kg/cm3이고, 이때 노즐에서 분출되는 물방울(직경:156-102마이크로미터)의 이동속도는 40-70m/sec가 된다. 이 경우 냉각실에서의 체류시간은 2-6초 정도이도, 증발효율은 95%정도이다.The above-mentioned coolers forcibly cool down the temperature of the exhaust gas by spraying water on the way through the hot exhaust gas. At this time, the smaller the diameter of the water droplet particles of the sprayed water, the better the evaporation efficiency and the shorter the evaporation time. In order to have a high evaporation efficiency, the spray pressure of the spraying port is generally about 10-30 kg / cm 3 , and the moving speed of the droplets (diameter: 156-102 micrometers) ejected from the nozzle is 40-70 m / sec. In this case, the residence time in the cooling chamber is about 2-6 seconds and the evaporation efficiency is about 95%.
이론상으로 설계된 스프레이냉각타입 배가스냉각장치는 실제 운전을 하다보면 완전히 증발하지 않은 물이 냉각기 밑바닥에 고이게 되며, 이러한 물의 고임현상은 증발효율과 운전조건에 장애를 일으키게 된다.In theory, the spray-cooled flue-gas cooler designed in the real world has accumulated water that is not completely evaporated in the bottom of the cooler, and this high water phenomenon impedes the evaporation efficiency and operating conditions.
특히 도시쓰레기 소각로와 같이 운전조건에 변동이 많은 경우에는 배가스의 효율이 떨어지면서 증발되지 않은 물의 량이 많아지게 되고, 가스의 흐름에 문제(trouble)가 발생되기도 한다. 이러한 문제는 보일러 가동중단의 문제점으로 발전되므로 냉각수의 완전한 증발은 필요하다.In particular, when there are a lot of fluctuations in operating conditions, such as urban waste incinerators, the efficiency of the flue-gas decreases, and the amount of unevaporated water increases, causing problems in gas flow. This problem develops as a problem of boiler shutdown, so complete evaporation of the coolant is necessary.
본 고안은 이를 감안하여 냉각기의 바닥에 고이는 물을 증발율을 높이고, 냉각효율을 개선하기 위한 냉각장치를 제공하는 데에 그 목적이 있다.The object of the present invention is to provide a cooling apparatus for increasing the evaporation rate of water accumulated on the bottom of the cooler and improving the cooling efficiency.

본 고안의 이와같은 목적은 배가스 냉각장치에 있어서,병류식 혹은 향류식의 워터스프레이구조를 갖는 1차 냉각수단; 및 상기 1차냉각수단과 연결되어 2차적인 냉각이 이루어지도록 워터스프레이가 냉각수단의 상단내측에서 직하방으로 일렬로 분사되는 분사방식의 확장된 형태의 횡형냉각수단을 포함하는 배가스 냉각장치로서 달성된다.This object of the present invention is a flue gas cooling apparatus, comprising: primary cooling means having a co-current or countercurrent type water spray structure; And a horizontal type cooling means of an extended type in which the water spray is sprayed in a row from the inside of the upper end of the cooling means in a straight line so as to perform secondary cooling in connection with the primary cooling means. .
이하 본 고안의 바람직한 실시예를 첨부 도면에 따라 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
첨부 도면중 도 2는 본 고안 전자선 가속기의 배가스냉각장치를 나타내는 개략도이다. 이 도면에 따르는 본 고안은 전체적으로 2단의 냉각구조를 갖는다.2 of the accompanying drawings is a schematic diagram showing an exhaust gas cooling device of the inventive electron beam accelerator. The present invention according to this figure has a two-stage cooling structure as a whole.
즉, 본 고안 냉각기(200)는 크게 제 1냉각기(210)와, 이에 연결된 제 2냉각기(220)로 이루어진다.That is, the present invention cooler 200 is largely composed of a first cooler 210 and a second cooler 220 connected thereto.
제 1냉각기(210)측 상단에는 배가스입구(212)를 형성하고, 그 내측으로 워터스프레이(211)를 종래 병류식 냉각기의 구조와 같이 설치한다. 물론 제 1냉각기(210)에는 배수구(213)를 형성한다.The exhaust gas inlet 212 is formed at the upper end of the first cooler 210 side, and the water spray 211 is installed inside the same as the structure of the conventional co-current cooler. Of course, the first cooler 210 is formed with a drain 213.
제 2냉각기(220)는 상기 제 1냉각기(210)와 달리 수직분사의 분사노즐로 이루어진 워터스프레이(221)를 형성하며, 배수구는 설치하지 않는다.Unlike the first cooler 210, the second cooler 220 forms a water spray 221 made of vertically sprayed nozzles, and does not have a drain hole.
상기한 제 1냉각기(210)와 제 2냉각기(220)는 소정의 연결관(214)로 연결된다. 따라서 1차 냉각된 배가스로부터 발생된 물은 제 2냉각기(220)으로 이동하지 않는다.The first cooler 210 and the second cooler 220 are connected to a predetermined connection pipe 214. Therefore, water generated from the first cooled exhaust gas does not move to the second cooler 220.
제 2냉각기(220)로부터 냉각된 배가스는 증발효율이 크게 개선된 상태로 배가스출구(222)를 통하여 배출된다.The exhaust gas cooled from the second cooler 220 is discharged through the exhaust gas outlet 222 in a state where the evaporation efficiency is greatly improved.
본 고안 냉각장치는 고온의 배가스를 흘러가는 도중에 물을 분무하므로써 배가스의 온도를 강제 냉각시킨다. 이때 분무하는 물의 물방울 입자의 직경은 작을수록 증발효율이 좋고, 증발시간도 단축된다.The cooling device of the present invention forcibly cools the temperature of the exhaust gas by spraying water on the way through the high temperature exhaust gas. At this time, the smaller the diameter of the water droplet particles of the sprayed water, the better the evaporation efficiency and the shorter the evaporation time.
높은 증발효율을 갖기 위한 본 고안의 분출구의 분무수압은 약 10-30kg/cm3이고, 노즐에서 분출되는 물방울(직경:156-102마이크로미터)의 이동속도는 40-70m/sec가 된다. 이 경우 냉각실에서의 체류시간은 2-6초 정도이고, 증발효율은 95%정도이다.Spray water pressure of the jet of the present invention to have a high evaporation efficiency is about 10-30kg / cm 3 , the moving speed of the water droplets (diameter: 156-102 micrometers) ejected from the nozzle is 40-70m / sec. In this case, the residence time in the cooling chamber is about 2-6 seconds and the evaporation efficiency is about 95%.
본 고안은 냉각기의 바닥에 고이는 물의 증발율을 높이고, 2단에 걸친 냉각장치를 구현하므로서 냉각효율을 개선하게 되었고, 배가스 처리후의 물에 의한 증발율 저하의 문제점을 개선하므로서 운전조건의 장애를 방지하는 효과도 있다.The present invention improves the cooling efficiency by increasing the evaporation rate of water accumulated at the bottom of the cooler, and implements a cooling system in two stages, and prevents the obstacle of operating conditions by improving the problem of lowering the evaporation rate by water after the exhaust gas treatment. There is also.
