상기 소각 및 연소 처리시스템의 SCR촉매탑(9) 및 SNCR(2)은 모두 질소산화물 처리설비로서, SCR촉매탑(9)의 경우 환원제로 NH₃, CO, H2S 등을 사용, NH₃가스 → 배기가스에 분사 → TiO₂또는 V2O5 촉매층을 통과하게 되며 보통 200∼400℃ 정도의 운전조건에서 운전되나 최적 탈질반응온도는 220∼350℃ 이며 220℃ 이하의 온도에서는 촉매 활성이 저하, 450℃ 이상의 온도에선 NH₃가 산화분해가 되며, 저온에서 내장된 촉매에 암모니아가스를 분사하여 소각로(1)의 질소산화물을 제거하기 위한 목적으로 설치되며 이와는 반대로 상기 SNCR(2)의 경우 촉매없이 870∼1,200℃ 온도범위의 고온 배출가스에 요소수 또는 암모니아수를 소각로(1) 내부에 직접 분사하게 되는 질소산화물 처리설비로 상기 SCR촉매탑(9)에 비해 설비 및 유지관리가 저렴한 장점을 지니고 있다.The SCR catalyst tower 9 and SNCR 2 of the incineration and combustion treatment system are both nitrogen oxide treatment facilities, and in the case of the SCR catalyst tower 9, NH₃, CO, H 2 S, etc. are used as reducing agents, NH₃ gas → Injection into the exhaust gas → passes through the TiO₂ or V 2 O 5 catalyst bed and is usually operated under operating conditions of 200 ~ 400 ℃, but the optimum denitrification reaction temperature is 220 ~ 350 ℃ and the catalyst activity decreases at the temperature below 220 ℃, 450 At temperatures above ℃, NH₃ is oxidatively decomposed, and is installed for the purpose of removing nitrogen oxides from the incinerator 1 by injecting ammonia gas into the built-in catalyst at a low temperature. It is a nitrogen oxide treatment facility which directly injects urea water or ammonia water into the incinerator 1 in a high temperature exhaust gas in a temperature range of 1,200 ° C., and has an advantage of low installation and maintenance compared to the SCR catalyst tower 9.

한편, 상기 질소산화물 처리를 위해 상기 반건식반응탑(4)과 SCR촉매탑(9) 사이에 설치되는 집진장치(7)는 도 4 내지 도 6에 도시된 바와 같이 덮개(106)를 갖는 함체 형태로 구성되어 내부에 청정가스배출공간부(101)가 마련됨과 동시에 여과포 탈진용 공기분사를 위한 에어노즐(103) 과, 비산재포집 및 산성가스제거용 소석회가 코팅된 다수의 백필터(102)가 수용되며 저부에 개폐도어(105)가 구비된 호퍼(104)가 일체로 연결된 다수의 백필터수용체(100)가 평면상 직사각형의 형태로 구획되어 상기 백필터수용체(100) 사이의 상부 공간에 청정가스출구덕트(300)가 에어노즐(103)이 설치된 백필터수용체(100)의 청정가스배출공간부(101)쪽에 연결됨과 동시에 하부 호퍼(104)측에 차단댐퍼(201)를 갖는 배기가스유입덕트(200)가 각각 설치되어 상기 소각로(1)측과 연결된 배기가스유입덕트(200)쪽으로 소각로(1)의 가스가 유입되어 백필터수용체(100)의 백필터(102)를 통해 청정가스출구덕트(300)로 처리된 가스를 배출시키게 되는 구조를 취하고 있다.Meanwhile, a dust collector 7 installed between the semi-dry reaction tower 4 and the SCR catalyst tower 9 for treating the nitrogen oxides is a housing having a cover 106 as shown in FIGS. 4 to 6. Consisting of a clean gas discharge space 101 is provided inside the air nozzle 103 for the air spray 103 for the filter cloth dust exhaustion, and a plurality of bag filter 102 coated with fly ash for collecting fly ash and acid gas removal A plurality of bag filter receptors 100 which are accommodated and in which a hopper 104 having an opening and closing door 105 at a bottom thereof are integrally connected are partitioned into a planar rectangular shape to clean the upper spaces between the bag filter receptors 100. The gas outlet duct 300 is connected to the clean gas discharge space 101 side of the bag filter receiver 100 in which the air nozzle 103 is installed, and at the same time, the exhaust gas inlet having the blocking damper 201 on the lower hopper 104 side.

In the case of the catalyst tower 9, the installation area is excessively occupied, and the cost of the facility and the maintenance are excessively expensive. Therefore, the catalyst tower 9 is not only limited in efficiently configuring the incineration and combustion treatment system, but also incineration and There is a problem that the size of the combustion treatment system is increased.

본 발명의 작용에 대하여 설명하면 다음과 같다.Referring to the operation of the present invention.

본 발명은 소각로(10)에서 배기가스가 약 900∼1000℃정도에서 연소되면 여기서 발생한 배기가스가 보일러(30)을 통과하여 배기가스 온도를 약 220∼250℃로 낮추어 주게 되고 보일러(30) 후단의 반건식반응탑(40)을 통과하여 배기가스의 온도를 약 150∼170℃로 낮추어주게 되며 이어서 촉매(73)가 내설된 집진장치(70)를 통과하면서 각종 유해 물질들을 처리하게 된다.In the present invention, when the exhaust gas is burned at about 900 to 1000 ° C. in the incinerator 10, the exhaust gas generated therethrough passes through the boiler 30 to lower the exhaust gas temperature to about 220 to 250 ° C., and the rear end of the boiler 30. After passing through the semi-dry reaction tower 40 of the lower the temperature of the exhaust gas to about 150 ~ 170 ℃ and then the catalyst 73 is passed through the dust collector 70 is built-in to treat various harmful substances.

여기서 상기 반건식반응탑(40)을 설치하는 이유는 약 180∼200℃ 정도에서 저온부식이 발생되기 때문에 상기 반건식반응탑(40)에서 배기가스를 급격히 냉각시켜 주기 위해 설치하고 있는 것이며 본 발명에서는 상기 저온부식을 피해 질소산화물을 제거할 수 있는 초저온촉매(73)를 사용한 집진장치(70)에서 질소산화물이 처리될 수 있도록 함과 아울러 집진장치(70) 전단에 소석회 주입을 위한 소석회주입설비(50) 및 활성탄 주입을 위한 활성탄주입설비(60), 그리고 암모니아 가스를 분사하기 위한 암모니아공급설비(80)에 의해 배기가스의 각종 유해물질도 함께 제거될 수 있도록 하고 있는 것이다.The semi-dry reaction tower 40 is installed in order to cool the exhaust gas rapidly in the semi-dry reaction tower 40 because low temperature corrosion occurs at about 180 to 200 ° C. A hydrated lime injection facility for injecting slaked lime into the front of the dust collector (70) as well as allowing the nitrogen oxide to be treated in the dust collector (70) using the ultra low temperature catalyst (73) capable of removing nitrogen oxides from low temperature corrosion (50). ) And activated carbon injection facility (60) for injection of activated carbon, and ammonia supply facility (80) for injecting ammonia gas to remove various harmful substances in the exhaust gas.

질소산화물 제거를 위한 암모니아 분사에서의 경우는 타입에 따라 세가지 운전방법을 선택할 수 있다.In the case of ammonia injection for NOx removal, three operating methods can be selected depending on the type.

첫 번째로 소각로(10)에 분사하는 방식을 예로 들게 되면, 기존에도 소각로(10)에 분사하는 SNCR(20)을 이용한 운전방식이 알려져 있다. 그러나 상기 운전방식은 암모니아 또는 요소수와 질소산화물과 미반응 물질이 완벽히 제거되지 아니한 상태로 대기중으로 방출되는 문제점을 안고있기 때문에 소각 및 연소 처리시스템에 본 발명을 적용하게 되면 소각로(10)에서 분사한 암모니아 성질의 미반응 물질이 집진장치(70)의 촉매(73)를 통과하면서 한번 더 반응한 다음 미반응 물질의 대기방지설비에 의해 한번 더 반응하게 되므로 질소산화물을 완벽하게 제거할 수 있게 되는 장점을 지니고 있다.Firstly, the method of spraying on the incinerator 10 is exemplified, and a driving method using the SNCR 20 spraying on the incinerator 10 is known. However, since the operation method has a problem that ammonia or urea and nitrogen oxides and unreacted substances are released to the air without being completely removed, when the present invention is applied to the incineration and combustion treatment system, the incinerator 10 is injected from the incinerator 10. The unreacted substance of the ammonia property is reacted once more while passing through the catalyst 73 of the dust collector 70 and then once again by the atmospheric prevention equipment of the unreacted substance, thereby completely removing nitrogen oxides. It has advantages.

그리고 두 번째로 집진장치(70)의 전단에 분사하는 방식은 집진장치(70) 전단에 각종 약품과 함께 암모니아가스를 분사하여 질소산화물을 제거할 수 있도록 하는 운전방식으로써 기존의 SCR촉매탑(90) 전단에 분사하는 것보다 집진장치(70) 전단에 분사할 경우 배기가스가 집진장치(70)의 백필터 층을 통과함과 동시에 배기가스의 질소산화물과 암모니아가스가 골고루 분포되어 촉매(73)를 통과하게 되어 질소산화물과 암모니아와 반응효율을 높일 수 있는 이점이 있다.And secondly, the method of spraying on the front of the dust collector 70 is a driving method to remove nitrogen oxides by injecting ammonia gas with various chemicals on the front of the dust collector 70, the conventional SCR catalyst tower 90 When spraying to the front of the dust collector 70, rather than spraying at the front end, the exhaust gas passes through the bag filter layer of the dust collector 70, and the nitrogen oxide and ammonia gas of the exhaust gas are evenly distributed. Passing through has the advantage to increase the reaction efficiency with nitrogen oxides and ammonia.

세 번째로 소각로(10) 및 집진장치(70) 전단에 분사하는 운전방식의 경우에는 상기 소각로(10)에 분사하는 방식과 집진장치(70)의 전단에 분사하는 방식를 동시에 병행하게 되는 운전방식으로써 많은량의 질소산화물이 발생되는 소각로에 적합한 운전방식이다.Third, in the case of the operation method for spraying the incinerator 10 and the front of the dust collector 70, the method of spraying the incinerator 10 and the method of spraying on the front of the dust collector 70 at the same time as the operation method It is suitable for the incinerator where a large amount of nitrogen oxide is generated.

상기와 같이 촉매(73)를 집진장치(20)에 구성하게 되면 소각 및 연소 처리시스템에 별도의 SCR촉매탑(90)이 별도로 요구되지 아니하므로 상기 SCR촉매탑(90)의 구성에 따르는 부지확보는 물론 관련 설비비 및 유지관리에 소요되는 비용을 절감할 수 있게 되며 그 뿐만 아니라 집진장치(70)가 기본적인 작용과 함께 SCR촉매탑이(90)이 수행하는 작용을 동시에 수행할 수 있게 됨에 따라 소각처리시템을 보다 효율적으로 구성할 수 있게 되며 또한 집진장치(70)의 청정가스배출공간부(71)에 설치된 촉매(73)를 간단히 취출하거나 촉매(73)의 사용기간에 따라 부분적으로 교체가 가능하기 때문에 촉매(73)의 사용기간을 연장할 수 있고, 저온의 SCR운전 및 촉매(73)가 요구되지 않는 고온의 운전인 SNCR(20)의 단독운전은 물론 이들의 병행 운전도 가능할 뿐만 아니라 공정상 유해 배기가스 물질의 농도 및 용량에 따라 집진장치(70)를 복수개로 설치하여 배기가스의 유해물질인 NOx, SOx, HCl, 다이옥신, 비산재(FLY ASH) 등의 처리능력을 강화시킬 수 있게 되는 등 다양한 장점이 있다.When the catalyst 73 is configured in the dust collector 20 as described above, since a separate SCR catalyst tower 90 is not separately required for the incineration and combustion treatment system, the site according to the configuration of the SCR catalyst tower 90 is secured. Of course, it is possible to reduce the cost of the associated equipment costs and maintenance, as well as the dust collecting device 70, along with the basic operation can perform the operation performed by the SCR catalyst tower (90) at the same time incineration The treatment system can be configured more efficiently, and the catalyst 73 installed in the clean gas discharge space 71 of the dust collector 70 can be simply taken out or partially replaced according to the service period of the catalyst 73. As a result, the service life of the catalyst 73 can be extended, and the SCR operation at low temperature and the independent operation of the SNCR 20, which is a high temperature operation at which the catalyst 73 is not required, as well as parallel operation thereof are possible. Process By installing a plurality of dust collectors 70 according to the concentration and capacity of the exhaust gas material, it is possible to enhance the processing capacity of NOx, SOx, HCl, dioxin, FLY ASH, etc. There are various advantages.
