Description
본 고안은 소각로나 발전소로부터 배출되는 배가스내에 포함된 유해가스 (HCℓ, SO2, NOx)와 분진 그리고 다이옥신등을 동시에 처리할 수 있도록한 장치에 관한 것으로, 특히 HCℓ과 SO2는 소석회를 투입하여 CaSO3와 CaCI2로 반응시켜 활성탄소 섬유 필터백에서 제거하고, NOx는 활성탄소의 활성을 이용하여 촉매반응으로 제거하고 더스트(dust)는 필터백에서 CaSO3, CaCI2와 함께 제거되도록 한 것이다.The present invention relates to a device that can simultaneously handle harmful gases (HCℓ, SO 2 , NOx), dust and dioxin contained in the flue gas discharged from an incinerator or power plant, and especially HCℓ and SO 2 CaSO 3 is reacted with CaCI 2 to remove from activated carbon fiber filter bag, NOx is removed by catalytic reaction using activated carbon activity and dust is removed together with CaSO 3 and CaCI 2 from filter bag.
종래에는 SO2, HCℓ을 제거하기 위하여 소석회를 덕트내에 투입하여 백필터에서 포집하도록 하는 건식법을 사용하거나 소석회 슬러리를 Spray Drying Reactor내에 투입하여 건조와 제기반응을 동시에 수행하고 백필터에서 포집하는 반건식 방식을 사용하고 있다.Conventionally, in order to remove SO 2 and HCℓ, a dry method in which slaked lime is introduced into a duct and collected in a bag filter or a slaked lime slurry is injected into a Spray Drying Reactor to simultaneously perform drying and raising reactions and to be collected in a bag filter. I'm using.
그리고 NOx는 추가의 촉매탑에 NH3를 주입하여 N2와 H2O로 환원시켜 제거하였다. 그러나 상기의 방법들은 처리효율이 기대치에 미치지 못함은 물론, 가격면에서 도 비 경제적이었고, 설치면적이 많이 소요되어 불함리한 점이 있었다.And NOx was removed by injecting NH 3 to an additional catalyst tower to reduce to N 2 and H 2 O. However, the above methods were not only inferior to the expected treatment efficiency, but also uneconomical in terms of price, and were unreasonable due to the large amount of installation area.
본 고안은 상기와 같은 제반 문제점을 감안하여 이를 해소하고자 고안한 것으로, 촉매탑과 백필터를 하나의 설비로 묶어 배가스내에 존재하는 SO2, HCℓ, NOx 분진을 동시에 처리하도록 한 분진/가스 동시처리 장치를 제공함에 그 목적이 있다.The present invention was devised to solve this problem in consideration of the above-mentioned problems. Simultaneous treatment of dust / gas which combines the catalyst tower and the bag filter into one facility to simultaneously treat SO 2 , HCℓ and NOx dust present in the exhaust gas The object is to provide a device.
이와같은 목적을 갖는 본 고안은 SOx/NOx/HCℓ/dust등을 동시에 처리할 수 있도록 덕트의 입측 상부에는 소석회 공급모터가 설치된 소석회 투입장치를 설치하고, 이의 전방 하부에는 덕트내로 암모니아 가스를 스프레이 해주는 암모니아 가스 투입장치를 설치하였으며, 덕트의 출구에는 SOx/NOx/HCℓ/dust등을 휠터링 해주는 활성탄소 또는 벌집형 촉매등으로된 필터백를 설치하여서 됨을 특징으로 한다.The present invention with this purpose is to install a slaked lime feeder equipped with a slaked lime feed motor at the upper part of the mouth of the duct so that the SOx / NOx / HCℓ / dust can be processed at the same time. The ammonia gas injector is installed and the outlet of the duct is characterized by the installation of a filter bag made of activated carbon or honeycomb catalyst that filters SOx / NOx / HCℓ / dust.

본 고안은 먼저 도 1에서 도시된 바와같이 덕트(10)의 입측 상부에 소석회 공급모터(21)가 설치된 소석회 투입장치(20)를 설치하여 덕트(10)내로 소석회를 투입하도록 구성하였다.The present invention was first configured to insert the lime into the duct 10 by installing the slaked lime input device 20 is installed in the upper side of the mouth of the duct 10 as shown in FIG.
그리고 상기 소석회 투입장치(20)가 설치된 덕트(10)의 전방 하부에는 덕트(10)내로 암모니아 가스를 스프레이 해주는 암모니아 가스 투입장치(30)를 설치하여 덕트(10)내로 암모니아 가스를 스프레이 하도록 구성하였다.In addition, an ammonia gas injector 30 for spraying ammonia gas into the duct 10 is installed at the front lower portion of the duct 10 in which the slaked lime injector 20 is installed to spray ammonia gas into the duct 10. .
또한 상기 덕트(10)의 출구에는 SOx/NOx/HCℓ/dust등을 휠터링 해주는 활성탄소 또는 벌집형 촉매등으로된 필터백(40)를 설치하였다In addition, at the outlet of the duct 10, a filter bag 40 made of activated carbon or honeycomb catalyst for filtering the SOx / NOx / HCℓ / dust is installed.
이와같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
본 고안은 덕트(10)의 입측 상부에 설치된 소석회 투입장치(20)와, 덕트(10)의 하부에 성치된 암모니아 가스 투입장치(30)로부터 덕트(10)로 소석회와 암모니아 가스를 공급하면 덕트(10)내의 SO2와 HCℓ가스는 아래의 반응식에 의하여 CaSO3, CaCI2로 전환된 입자상으로 변화된다.According to the present invention, when the slaked lime and ammonia gas are supplied to the duct 10 from the slaked lime injector 20 installed at the upper part of the mouth side of the duct 10 and the ammonia gas injector 30 formed at the lower part of the duct 10, the duct 10 SO 2 and HC1 gas in (10) are converted into particulates converted into CaSO 3 and CaCI 2 by the following reaction equation.
Ca(OH)2+ SO2-> CaSO3·1/2H2O + 1/2 H2OCa (OH) 2 + SO 2- > CaSO 3 1 / 2H 2 O + 1/2 H 2 O
이와같은 반응후 미반응한 소석회와 반응생성물은 상기 덕트(10)의 출구에 설치된 활성탄소 또는 벌집형 촉매등으로된 필터백(40)에 의해서 포집된다.After this reaction, unreacted slaked lime and the reaction product are collected by the filter bag 40 made of activated carbon or honeycomb catalyst, etc. installed at the outlet of the duct 10.
이때 온도가 200℃정도를 유지하게 되면 활성섬유의 연소없이 암모니아 주입에 의한 촉매환원반응을 유도할 수 있게 된다.At this time, if the temperature is maintained at about 200 ℃ can be induced catalytic reduction reaction by ammonia injection without burning the active fiber.
또한 벌집형 촉매의 경우 압력손실이 작게 유지될 수 있으므로 효과적인 탈진을 위한 역세가 가능하게 된다.In addition, in the case of the honeycomb catalyst, since the pressure loss can be kept small, backwashing for effective exhaustion is possible.
이상과 같은 본 고안은 촉매탑과 필터백를 하나의 장치로 묶을 수 있으며 SOx/NOx/HCℓ/dust를 동시에 처리할 수 있어 대기오염을 예방할 수 있음은 물론, 설비의 간단화로 경제성을 유지할 수 있는 효과가 있다.As described above, the present invention can bundle the catalyst tower and the filter bag into a single device, and can simultaneously process SOx / NOx / HCℓ / dust to prevent air pollution, as well as to maintain economic efficiency by simplifying the equipment. There is.
