Abstract

A wet type electric ionizer is provided to improve the removal efficiency of particulate matter and gaseous matter included in the exhaust gas by increasing a contact area in an intermediate region by collision energy by jetting the sprayed water from the corresponding direction when the exhaust gas flows into a duct inlet pipe. In a wet type electric ionizer, the gas firstly treated by a sprayer in an inlet pipe receiving the exhaust gas passes through a packing layer(20), when the gas flows into a desulfurization tower. The gas is secondly treated in the packing layer by increasing a gas-liquid contact area at the upper side by solution jetted from a spray nozzle. When the gas treated in the desulfurization tower passes through the inside of a dust collecting pipe(50), the gas is ionized by an electrode rod(60) installed in the dust collecting pipe and collected on the inner wall of the dust collecting pipe. The flow velocity of the gas flowing into the packing layer gets fast by making an area of the desulfurization tower having the packing layer, smaller than an area of an electrostatic dust collecting unit. The spray amount is increased per unit area by forming a spray layer jetted from the upper side of the packing layer of the desulfurization tower, in the desulfurization tower having a reduced area. The electrostatic dust collecting unit formed at the upper side of the packing layer is expanded by an inclined surface(15) formed at a part where the electrostatic dust collecting unit is connected to the desulfurization tower.

본 발명은 습식전기 이오나이져에 관한 것으로, 특히 처리하고자 하는 입자상물질과 가스상물질이 혼합되어진 고온의 배기가스가 덕트 인입관으로 유입되어 분사노즐을 통하여 스프레이되는 분사액에 의하여 냉각되면서 처리가능한 입자상의 물질이 제거토록 된 후 이들 다시 탈황탑에서 인입관에서 처리하지 못한 가스상물질을 2차 처리할 경우에 1차 처리되어진 가스상물질이 함유한 배기가스가 인입구를 통하여 탈황탑로 상승할 경우에 유속이 느려 패킹층의 단위면적당 분사되는 분사액이 적어 패킹층의 막힘현상 등에 의하여 가스상물질의 제거효율이 저하되었던 것을 해결하고자 한 것이고 이를 탈황탑의 구조적인 변경으로 간단하게 해결하고자 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet electric ionizer. Particularly, a high-temperature exhaust gas containing a mixture of particulate matter and gaseous material to be treated is introduced into a duct inlet pipe and cooled by the spray liquid sprayed through the spray nozzle. In the case of secondary treatment of gaseous material which was not treated in the inlet pipe in the desulfurization tower after being removed, the flow rate when the exhaust gas containing the first treated gaseous material rises through the inlet to the desulfurization tower The slow injection liquid per unit area of the packing layer is slowed to solve the problem that the removal efficiency of the gaseous material is lowered due to the clogging of the packing layer, etc. This is simply to solve the structural change of the desulfurization tower.

현재 보일러나 소각로 또는 각종 산업설비 등에서 배출되는 배기가스에는 황산화물(SOx),염화수소(HCl), 불화수소(HF)등의 가스상의 물질과 먼지나 그보다 작은 입자상의 미스트(Mist)등의 입자상의 물질을 함유하고 있어 대기로 배출되기 전에 습식전기이오나이져를 거쳐 가스상의 물질은 물론 입자상의 물질을 완전하게 처리하게 되는 것이다.Exhaust gases emitted from boilers, incinerators, and other industrial facilities currently contain gaseous substances such as sulfur oxides (SO x ), hydrogen chloride (HCl), and hydrogen fluoride (HF), and particulates such as dust and smaller particulate mists. It contains the substance of, and before it is discharged to the atmosphere, it is processed through the wet electric ionizer to completely process the particulate matter as well as the gaseous substance.

그러나 이러한 습식전기이오나이져는 통상 입자상물질과 가스상물질이 함유된 상태에서 고온이기 때문에 탈황탑(100)에서 가스상의 물질등을 처리하고자 할 경우에 또는 정전집진부(200)에서 처리하고자 할 경우에 포화온도까지 떨어트리지 못할 경우에는 제거효율이 떨어진다는 단점이 있는 것이다.However, since the wet electric ionizer is usually high temperature in the state of containing particulate matter and gaseous substances, it is saturated when it is desired to treat gaseous substances and the like in the desulfurization tower 100 or in the electrostatic precipitator 200. If it can not drop to the temperature is the disadvantage that the removal efficiency is reduced.

따라서 대부분 배기가스가 인입되어지는 덕트상의 인입관(Duct)에는 분사되어지는 분사노즐(11)에 의하여 1차로 고온의 배기가스를 냉각하면서 입자상의 물질을 제거하게 되는 것이다.Therefore, the particulate matter is removed while primarily cooling the high-temperature exhaust gas by the injection nozzle 11 that is injected into the inlet pipe Duct on which the exhaust gas is introduced.

또한 이렇게 제거되어진 배기가스는 1차로 냉각하거나 제거되지 못한 입자상의 물질이나 제거가 가능한 가스상물질을 제거하기 위하여 기 액접촉을 늘려주는 패킹층(20)과 상기 패킹층에 순환수를 이용하여 분사액을 분사토록 하기 위한 스프 레이층(30)과 상기 순환수를 모으는 탱크(40)와 상기 스프레이층에 순환수를 공급하기 위한 순환펌프등으로 구비토록 되는 탈황탑(Absorber)(100)이 형성되고, 상기 탈황탑(100)에서 처리하지 못한 가스는 집진관(50)과 그 중앙에 위치되어지는 전극봉(60)등에 의하여 코로나 전류를 발생시켜 상승되는 가스 등을 이온화하여 집진관의 내벽에 접착되어 집진을 하게 되고 집진된 것의 제거를 위한 세정장치등으로 구성되어지는 정전집진부(ESI)(200)로 이루어져 제거하게 되는 것이다.In addition, the exhaust gas thus removed is first packed or packed with a liquefied water in the packing layer 20 to increase the gas contact to remove the particulate matter that can not be cooled or removed, or the gaseous material that can be removed by using the circulating water to the packing layer. A desulfurization tower (Absorber) 100 is provided which is provided with a spray layer 30 for spraying the water, a tank 40 collecting the circulating water, and a circulating pump for supplying the circulating water to the spray layer. The gas not processed in the desulfurization tower 100 is ionized by the dust collector tube 50 and the electrode rod 60 positioned at the center thereof to generate a corona current, and is then ionized to the inner wall of the dust collector tube. The dust is collected and removed by the electrostatic dust collection unit (ESI) 200 which is configured as a cleaning device for removing the dust.

그러나 종래의 탈황탑(100)으로 진입되는 가스의 유속이 0.5∼0.7m/sec에 불과하여 패킹층(20)의 막힘현상이 발생하게 되어 가스상물질의 제거효율이 저하된다는 단점이 있는 것이었다.However, since the flow rate of the gas entering the conventional desulfurization tower 100 is only 0.5 to 0.7 m / sec, clogging of the packing layer 20 occurs, so that the removal efficiency of the gaseous substance is lowered.

이는 탈황탑(100)과 정전집진부(200)의 사이즈가 동일하게 설계됨으로 유속을 빠르게 할 수 없었던 것이다.This is because the size of the desulfurization tower 100 and the electrostatic precipitator 200 is designed to be the same, the flow rate could not be faster.

따라서 본 발명은 처리하고자 하는 배기가스가 덕트 인입관으로 유입될 경우에 고온이면서 많은 입자상의 물질을 함유하게 됨으로 이를 1차적으로 냉각하고 입자상의 물질등을 집진토록 하기 위하여 물로 분사토록 할 경우에 이러한 분사를 1,2차로 구분되아 이들이 서로 대응되는 방향에서 분사가 이루어지도록 함으로서 서로 대응되게 분사되는 물과 배기가스가 서로 충돌하여 생기는 에너지에 의하여 접촉면적을 크게 하여 배기가스 내에 함유되어진 가스상물질과 입자상물질의 제거효율을 향상토록 한 것이고, 이와 같이 처리된 가스를 탈황탑으로 인입될 경우에 탈황탑을 정전집진부보다 상대적으로 폭을 좁게 형성함으로서 유속을 빠르게 증가 토록 하여 탈황탑의 면적을 작게 함으로서 순환수의 분사량도 단위면적당 많아지게 되어 패킹층의 막힘현상을 방지토록 한 것이다.Therefore, when the exhaust gas to be treated is introduced into the duct inlet pipe, it contains a high temperature and a lot of particulate matter. Therefore, when the exhaust gas to be treated is first sprayed with water to cool the particulate matter and collect the particulate matter. The injection is divided into 1st and 2nd, so that the injection is performed in the corresponding directions so that the contact area is enlarged by the energy generated by the collision of water and exhaust gas that are injected correspondingly to each other, so that the gaseous substances and particulate matter contained in the exhaust gas are increased. In order to improve the removal efficiency of the material, when the treated gas is introduced into the desulfurization tower, the desulfurization tower is formed to be relatively narrower than the electrostatic precipitating unit so that the flow velocity is increased quickly to reduce the area of the desulfurization tower to circulate. The amount of injection of water also increases per unit area, so that the membrane of the packing layer It is to prevent force phenomenon.

이러한 목적 달성을 위하여 본 발명에서는 처리하고자 하는 배기가스가 인입되어지는 인입관에 유입되는 배기가스 방향과 동일한 방향인 상측에서 하측으로 분사토록 되는 상측스프레이와 유입되는 배기가스와 반대방향인 하측에서 상측으로 분사토록 되는 하측스프레이를 형성하여 인입관을 통하여 유입되어지는 배기가스가 서로 대응되게 분사되는 물과 충돌하여 생기는 에너지에 의하여 접촉면적을 크게 하여 배기가스내에 함유되어진 가스상물질과 입자상물질의 제거효율을 향상토록 한 것이다.In order to achieve the above object, in the present invention, the upper sprayer is sprayed from the upper side to the lower side which is the same direction as the exhaust gas flowing into the inlet pipe into which the exhaust gas to be introduced is introduced, and the upper side from the lower side opposite to the incoming exhaust gas. The lower sprayer is sprayed to form the lower sprayer, and the contact area is increased by the energy generated by the collision of the exhaust gas flowing through the inlet pipe with the water sprayed correspondingly to remove the gaseous and particulate matter contained in the exhaust gas. To improve it.

또한 이와 같이 처리되어진 가스가 인입되어지는 탈황탑은 그 상측에 위치되어지는 정전집진부보다 상대적으로 폭을 좁게 형성하여 인입구로 인입되어지는 가스의 유속을 빠르게 함으로서 패킹층의 막힘을 방지하게 되는것이고, 또한 이렇게 면적이 작아짐으로서 단위면적당 분사되는 분사액이 증가하게 됨으로 기액접촉면적이 크게 됨으로 제거효율을 향상토록 할 수 있는 것이다.In addition, the desulfurization tower into which the treated gas is introduced is formed to have a relatively narrow width than the electrostatic precipitating unit located above, thereby preventing the packing layer from clogging by increasing the flow velocity of the gas introduced into the inlet. In addition, as the area is reduced, the injection liquid injected per unit area is increased, so that the gas-liquid contact area is increased, thereby improving the removal efficiency.

우선 본 발명의 기본적인 구성으로서 우선 처리하고자 하는 배기가스가 인입되어지는 인입관(10)과 상기 인입관(10)의 내부에서 분사장치(11)에 의하여 1차 처리되어진 가스가 인입구(14)를 통하여 탈황탑(100)로 인입되면 패킹층(20)을 통과하게 되고 상기 패킹층(20)에는 그 상측에서 분사노즐(30)에 의하여 분사되는 분사액에 의하여 기액접촉면적을 크게 하여 2차 처리하게 되고, 탈황탑(100)에서 처리 되어진 가스를 이온화하여 완전한 처리를 위하여는 집진관의 내부를 통과할 경우에 집진관(50)의 내부에 설치된 전극봉(60)에 의하여 이온화되면서 집진관의 내벽에 집진되어지고, 이와 같이 집진되어진 가스상의 물질등은 세정수단에 의하여 씻겨내려가게 되는 것이고, 이렇게 씻겨내려간 집진물질 등은 탈황탑(100)의 하단에 위치된 집진탱크(40)에 집진되어지고 집진되어진 것은 정화하여 순환펌프에 의하여 재활용하게 되고 재활용되어진 것은 다시 순환수로 사용되어지는 것이다.First, as the basic configuration of the present invention, the inlet pipe 10 through which the exhaust gas to be treated is introduced first and the gas primarily processed by the injection device 11 in the inlet pipe 10 are introduced into the inlet port 14. When introduced into the desulfurization tower 100 through the packing layer 20 passes through the packing layer 20 by increasing the gas-liquid contact area by the injection liquid sprayed by the injection nozzle 30 from the upper side to the secondary treatment In order to ionize the gas treated in the desulfurization tower 100 and pass through the inside of the dust collecting tube for complete treatment, the inner wall of the dust collecting tube is ionized by the electrode 60 installed inside the dust collecting tube 50. The gaseous substances collected in this way, and the like, are collected by the washing means, and the dust-collected substances, etc., thus washed off are collected in the dust collecting tank 40 located at the bottom of the desulfurization tower 100. It is been been high dust collection by purified and recycled by a circulation pump will be recycled to be used again as circulation.

이와 같은 습식전기이오나이져에서 본 발명은 도1 및 도2에 도시된 바와 같이 인입관(10)의 입구 상측에서 하측으로 분사토록 되는 상측스프레이(11)와 서로 대응되게 위치되어진 하측스프레이(12)가 하측에서 상측으로 분사토록 되고, 이때 상측스프레이(11)와 하측스프레이(12)는 분사되는 물이 서로 충돌할 정도의 거리를 유지하게 되며, 하측스프레이(12)가 장착된 인입관(10)의 후단으로는 인입관(10)의 입구보다 상대적으로 직경이 작게 축관부(13)가 형성되어 인입관(10)으로 유입되어진 배기가스가 인입관(10)의 입구에서 축관부(13)의 사이에 어느 정도 머물 수 있게 됨으로서 대응되게 분사되는 분무에 의하여 제거효율을 향상토록 한 것이다.In the wet electric ionizer as described above, the present invention has a lower spray 12 positioned corresponding to each other with the upper spray 11 to be sprayed downward from the upper side of the inlet of the inlet pipe 10 as shown in FIGS. 1 and 2. Is sprayed from the lower side to the upper side, at which time the upper spray 11 and the lower spray 12 maintain the distance that the water sprayed to collide with each other, the lower pipe 12 is equipped with the inlet pipe (10) The rear end of the shaft tube portion 13 is formed with a smaller diameter than the inlet of the inlet tube 10, the exhaust gas introduced into the inlet tube 10 is the inlet of the shaft tube portion 13 at the inlet of the inlet tube 10 By being able to stay to some extent between the spraying correspondingly sprayed to improve the removal efficiency.

또한 이와 같이 인입관(10)에서 포화온도까지 떨어진 배기가스는 인입관(10)의 축관부(13)를 통하여 빨라진 유속이 인입구(14)를 통하여 탈황탑(100)으로 인입되면 탈황탑(100)의 면적이 정전집진부(200)보다 상대적으로 작게 형성되어 인입구(14)로 인입된 배기가스는 일정한 압력에 의하여 유속이 빨라지게 되고 빨라진 배기가스는 패킹층(20)을 통과할 경우에 패킹층(20)의 상층에서 스프레이층(30)을 통하여 분사되어지는 분사액과 접촉하게 되는 것이다.In addition, the exhaust gas dropped to the saturation temperature in the inlet pipe 10 as described above is desulfurization tower 100 when the flow rate accelerated through the shaft pipe portion 13 of the inlet pipe 10 is introduced into the desulfurization tower 100 through the inlet 14 ) Area is formed to be smaller than the electrostatic precipitator 200, the exhaust gas introduced into the inlet 14 is a flow rate is increased by a constant pressure and the fast exhaust gas passing through the packing layer 20, the packing layer The upper layer 20 is in contact with the injection liquid to be injected through the spray layer 30.

이때 탈황탑(100)의 패킹층(20)의 상측에서 분사토록 되는 스프레이층(30)은 면적이 작아진 탈황탑(100)에 형성됨으로 면적이 작아진 상태에서 분사량은 종래와 동일하게 됨으로 상대적인 분사량이 단위면적당 많아지게 됨으로 많은 분사액으로 인하여 유속이 빨라진 가스가 패킹층(20)을 통과할 경우에 패킹층(20)의 막힘을 방지함은 물론 스프레이층(30)에서 분사되어지는 많은 양의 물의 기액접촉면적이 크게 됨으로 효율이 향상되어지는 것이다.At this time, the spray layer 30 sprayed from the upper side of the packing layer 20 of the desulfurization tower 100 is formed in the desulfurization tower 100 having a smaller area, so that the spraying amount in the state where the area is reduced becomes the same as in the related art. Since the amount of injection increases per unit area, when the gas having a faster flow rate due to a large amount of injection liquid passes through the packing layer 20, it prevents the packing layer 20 from clogging as well as a large amount that is injected from the spray layer 30. The efficiency of the gas-liquid contact area of water increases.

또한 패킹층(20)의 상측으로 형성되는 정전집진부(200)는 탈황탑(100)과 연결되는 부분에서 형성된 경사면(15)에 의하여 확관이 이루어짐으로 패킹층(20)을 통과한 가스는 압력이 줄어들게 되면서 골고루 퍼지게 된 상태에서 정전집진부(200)로 진입하게 되어 집진의 효율이 향상토록 되는 것이다.In addition, the electrostatic precipitator 200 formed above the packing layer 20 is enlarged by the inclined surface 15 formed at the portion connected to the desulfurization tower 100, so that the gas passing through the packing layer 20 has a pressure. As it decreases, the electrostatic precipitator 200 enters the electrostatic precipitator 200 while being evenly spread, thereby improving the efficiency of dust collection.

따라서 상측스프레이(11)과 하측스프레이(12)에서 분사되어지는 물이 서로 충돌하게 됨으로서 생기는 에너지에 의하여 인입관(10)으로 인입되어지는 배기가스와 접촉면적을 크게 하게 되어 처리하고자 하는 배기가스를 포화온도까지 떨어트리게 되는 것이고, 이와 같이 포화온도가지 떨어진 배기가스는 축관부(13) 및 상대적으로 작아진 탈황탑(100)의 면적에 의하여 빨라진 유속이 패킹층(20)을 빠르게 통과하게 되어 패킹층(20)의 막힘을 방지하게 되고, 또한 패킹층(20)의 상측에서 분사토록 되는 스프레이층(30)은 탈황탑(100)이 면적이 작아짐으로 인하여 상대적인 분사량이 단위면적당 많아지게 됨으로 많은 분사액으로 인하여 기액접촉면적을 크게 함으로서 제거효율을 향상토록 하는 것이다.Therefore, the water sprayed from the upper spray 11 and the lower spray 12 collides with each other to increase the contact area with the exhaust gas introduced into the inlet pipe 10 due to the energy generated. The exhaust gas is dropped to the saturation temperature, the exhaust gas is separated from the saturation temperature in this way, the flow rate accelerated by the area of the shaft tube portion 13 and the relatively small desulfurization tower 100 passes through the packing layer 20 quickly To prevent clogging of the packing layer 20 and spray layer 30 to be sprayed from the upper side of the packing layer 20, since the desulfurization tower 100 has a smaller area, the relative injection amount is increased per unit area. Due to the injection liquid, the removal efficiency is improved by increasing the gas-liquid contact area.

또한 패킹층(20)에서 제거된 가스는 정전집진부(200)로 진입될 경우에 그 상 측으로 형성된 경사면(15)에 의한 확관으로 압력이 제거되면서 골고루 퍼지게 되면서 정전집진부(200)로 균일하게 진입하게 되어 집진의 효율이 향상토록 되는 것이다.In addition, when the gas removed from the packing layer 20 enters the electrostatic precipitator 200, the gas is evenly spread as the pressure is removed by the expansion by the inclined surface 15 formed thereon, and uniformly enters the electrostatic precipitator 200. Thus, the efficiency of dust collection is improved.

이상에서 살펴본 바와 같이, 본 발명은 습식전기 이오나이져에서 처리하고자 하는 배기가스를 덕트 인입관으로 유입될 경우에 분사되는 물이 서로 대응되는 방향에서 분사가 이루어짐으로 그 중간영영에서의 충돌에너지로 인하여 접촉면적을 크게 하여 배기가스내에 함유되어진 가스상물질과 입자상물질의 제거효율을 향상토록 한 것이이고, 이와 같이 제거된 가스는 빠른 유속에 의하여 패킹층이 막힘이 방지되며 상대적으로 작아진 면적에 의하여 분사량이 단위면적당 많아지게 됨으로 기액접촉면적이 크게되어 제거효율이 향상되어지는 것이다.As described above, in the present invention, when the exhaust gas to be treated in the wet electric ionizer is introduced into the duct inlet pipe, the sprayed water is injected in a direction corresponding to each other, so that the collision energy in the intermediate region is generated. Therefore, the contact area is increased to improve the removal efficiency of gaseous and particulate matter contained in the exhaust gas, and the gas thus removed is prevented from clogging the packing layer due to the high flow rate and the relatively small area. As the injection amount increases per unit area, the gas-liquid contact area becomes large, and the removal efficiency is improved.
