Description

다중 흡수챔버를 갖는 습식 흡수탑{Absorption tower having multi-absorption chamber}Absorption tower having multi-absorption chamber

본 발명은 다중 흡수챔버를 갖는 습식 흡수탑에 관한 것이다.The present invention relates to a wet absorption tower having multiple absorption chambers.

대규모 소각시설이나 화력발전소의 보일러 또는 제철소 등에서 물질 연소시 발생하는 배기가스내의 염화수소(HCl)나 황산화물(SOx) 또는 불화수소(HF) 등의 산성성분은 인체에 매우 해로움은 물론 대기오염의 원인물질로서 다양한 방법을 통해 제거되고 있다.Acidic components such as hydrogen chloride (HCl), sulfur oxides (SOx), or hydrogen fluoride (HF) in the exhaust gases generated during the combustion of materials in large-scale incineration plants, boilers or steel mills, etc., are very harmful to humans and cause air pollution. As a substance, it is removed through various methods.

상기 배기가스내의 산성성분을 제거하기 위한 방법의 하나로, 배기가스를 흡수탑의 내부로 유도하고, 흡수탑 내부에 흡수액으로서의 알칼리성 용액(가령 소석회, Ca(OH)2)이나 슬러리를 분사하여, 고온의 배기가스가 알칼리성 물질과 접촉하도록 함으로써, 가스내의 산성물질을 알칼리성 물질로 흡수 및 중화시키는 방식이 있다. 상기 알칼리성 용액은 미립자 상태로 흡수탑 내부에서 가스와 접촉하며 가스 내부의 산성물질을 흡수하는 반응과정을 거친다. 상기 산성물질의 제거효율은 산성물질과 흡수액과의 접촉시간 및 접촉면적 그리고 흡수액의 pH에 따라 달라진다.As a method for removing acidic components in the exhaust gas, exhaust gas is introduced into the absorption tower, and an alkaline solution (such as slaked lime, Ca (OH) 2) or slurry as an absorption liquid is injected into the absorption tower to obtain a high temperature. By allowing the exhaust gas of to come into contact with the alkaline substance, there is a method of absorbing and neutralizing the acidic substance in the gas with the alkaline substance. The alkaline solution contacts the gas in the absorption tower in a particulate state and undergoes a reaction process of absorbing acidic substances in the gas. The removal efficiency of the acidic material depends on the contact time and the contact area between the acidic material and the absorbent liquid and the pH of the absorbent liquid.

도 1에 상기 중화반응을 위한 종래의 습식 흡수탑을 도시하였다.1 illustrates a conventional wet absorption tower for the neutralization reaction.

도시한 바와같이, 종래의 습식 흡수탑(11)은, 배기가스입구(13)를 통해 배기가스를 받아들이고 상부에 처리가스출구(15)를 가지며 흡수액(17)을 수용하는 반응탱크(35)와, 상기 반응탱크(35) 내의 상측부에 배치되는 다수의 노즐(31)과, 상기 흡수액(17)을 노즐(31)로 공급하기 위한 흡수액배출관(23)과 펌프(25)와 흡수액공급관(29)을 포함한다. 상기 흡수액(17)은 물과 소석회 또는 석회석 등이 혼합된 슬러리(slurry)상 또는 가성소다나 수산화마그네슘이 혼합된 용액이다.As shown in the drawing, the conventional wet absorption tower 11 includes a reaction tank 35 which receives exhaust gas through the exhaust gas inlet 13, has a processing gas outlet 15 thereon, and accommodates the absorbent liquid 17. In addition, a plurality of nozzles 31 arranged in an upper portion of the reaction tank 35, an absorbent liquid discharge pipe 23 for supplying the absorbent liquid 17 to the nozzle 31, a pump 25, and an absorbent liquid supply pipe 29 ). The absorbing liquid 17 is a slurry in which water and slaked lime or limestone are mixed, or a solution in which caustic soda or magnesium hydroxide is mixed.

또한 상기 반응탱크(35)의 측부에는 교반기(19)가 설치된다. 상기 교반기(19)는 흡수액(17)의 내부에 고형물이 가라앉아 고착되는 것을 막는 것으로서, 모터(19a)와, 상기 모터(19a)에 의해 회전하는 교반날개(19b)를 갖는다. 상기 모터(19a)의 회전력을 교반날개(19b)로 전달하는 샤프트는 반응탱크(35)의 측벽을 관통하여 반응탱크(35) 내부로 연장되어 있다.In addition, an agitator 19 is installed at the side of the reaction tank 35. The stirrer 19 prevents the solids from sinking and sticking inside the absorbent liquid 17. The stirrer 19 has a motor 19a and a stirring blade 19b that is rotated by the motor 19a. The shaft for transmitting the rotational force of the motor (19a) to the stirring blade (19b) extends through the side wall of the reaction tank 35 into the reaction tank (35).

도면부호 27은 배출라인이다. 상기 배출라인은 흡수액(17)의 일부를 외부의 용액배출탱크(미도시)로 보내는 통로이다.Reference numeral 27 is a discharge line. The discharge line is a passage for sending a portion of the absorbing liquid 17 to an external solution discharge tank (not shown).

상기 구성을 갖는 종래의 흡수탑(11)에 있어서, 상기 배기가스입구(13)를 통해 처리공간(33)으로 유입한 배기가스는, 처리가스출구(15)측으로 상향 이동하며 노즐(31)로부터 하향 분사되는 흡수액(17)과 접촉한다. 배기가스가 흡수액(17)과 접함에 따라 배기가스 내부의 산화물이 흡수액(17)과 반응하여 중화처리되고, 산화물이 제거된 가스는 처리가스출구(15)를 통해 외부로 배출된다.In the conventional absorption tower 11 having the above structure, the exhaust gas flowing into the processing space 33 through the exhaust gas inlet 13 moves upwardly toward the processing gas outlet 15 and moves from the nozzle 31. It comes in contact with the absorbing liquid 17 injected downward. As the exhaust gas comes into contact with the absorbent liquid 17, the oxide inside the exhaust gas reacts with the absorbent liquid 17 to be neutralized, and the gas from which the oxide is removed is discharged to the outside through the process gas outlet 15.

그런데 상기한 종래의 흡수탑(11)은, 흡수액의 산성가스 흡수능력에 한계가 있고, 흡수액과 배기가스와의 접촉시간이 짧아, 이를테면 2000ppm 이상의 고농도 SOx 함유 가스가 유입될 경우 산화물의 처리효율이 좋지 못하다는 단점을 갖는다. However, the conventional absorption tower 11 has a limit in absorbing acid gas of the absorbent liquid, and the contact time between the absorbent liquid and the exhaust gas is short. For example, when a high concentration of SOx-containing gas of 2000 ppm or more flows in, the treatment efficiency of the oxide is increased. The disadvantage is that it is not good.

즉, 배기가스가 흡수액과 접할 수 있는 시간은, 배기가스가 처리공간(33)에 머물러 있는 동안인데, 타워의 구조상 배기가스입구(13)를 통해 들어온 배기가스는 이어서 들어오는 배기가스에 밀려 처리가스출구(15)로 곧바로 빠져나가므로 그만큼 처리공간(33)내에 머무르는 시간이 짧고, 또한 처리시간이 충분한 경우라 하더라도 배기가스와 접촉하고 있는 흡수액 자체가 흡수할 수 있는 산성물질의 양도 한정되어 있으므로, 고농도의 배기가스를 한 번에 처리하지 못하는 것이다.That is, the time that the exhaust gas can come into contact with the absorbing liquid is while the exhaust gas stays in the processing space 33, and the exhaust gas that enters through the exhaust gas inlet 13 due to the structure of the tower is subsequently pushed by the incoming exhaust gas and the processing gas. Since it exits directly to the outlet 15, the amount of time the residence time in the processing space 33 is short, and even if the processing time is sufficient, the amount of acidic substances that can be absorbed by the absorbent liquid itself in contact with the exhaust gas is limited. It is not possible to process high concentrations of exhaust gases at once.

또한 상기한 종래의 흡수탑(11)은, 교반기(19)가 반응탱크(35)의 측부에 위치하므로, 반응탱크(35) 측벽을 관통한 교반기의 샤프트를 감싸는 실링장치가 필요하다. 상기 실링장치는 흡수액(17)이 반응탱크(35) 외부로 누출되는 것을 막기 위한 것으로서 지속적인 보수가 필요하다.In addition, in the conventional absorption tower 11, since the stirrer 19 is located at the side of the reaction tank 35, a sealing device is required to surround the shaft of the stirrer penetrating the side wall of the reaction tank 35. The sealing device is to prevent leakage of the absorbent liquid 17 to the outside of the reaction tank 35 and requires continuous maintenance.

본 발명은 상기 문제점을 해소하고자 창출한 것으로서, 고농도 산성 배기가스를 그 내부로 통과시키며 흡수액과 접촉하게 하는 흡수챔버를 다수 구비하여, 배기가스와 흡수액과의 접촉시간을 최대로 연장함으로써, 배기가스내 산화물의 제거효율이 높고, 또한 흡수액의 누설염려가 없어 실링을 위한 장치나 비용이 소요되지 않아 유지보수가 용이한 다중 흡수챔버를 갖는 습식 흡수탑을 제공함에 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and includes a plurality of absorption chambers that allow high concentration acid exhaust gas to pass therein and come into contact with an absorbing liquid, thereby extending the contact time between the exhaust gas and the absorbing liquid to the maximum, and thereby exhaust gas. It is an object of the present invention to provide a wet absorption tower having a multi-absorption chamber that is easy to maintain due to high removal efficiency of oxides and no fear of leakage of absorbent liquid, and thus no device or cost for sealing is required.

도 2는 본 발명의 일 실시예에 따른 다중 흡수챔버를 갖는 습식 흡수탑을 부분적으로 도시한 사시도이고, 도 3은 상기 도 2에 도시한 흡수탑의 동작을 설명하기 위하여 개략적으로 나타내 보인 도면이다.FIG. 2 is a perspective view partially illustrating a wet absorption tower having multiple absorption chambers according to an embodiment of the present invention, and FIG. 3 is a view schematically illustrating the operation of the absorption tower illustrated in FIG. 2. .

상기한 도면부호와 동일한 도면부호는 동일한 기능의 동일한 부재를 가리킨다.The same reference numerals as the above reference numerals denote the same members having the same function.

도시한 바와같이, 본 실시예에 따른 다중 흡수챔버를 갖는 습식 흡수탑(41)은, 흡수액(17)을 수용하는 흡수액탱크(43)와, 상기 흡수액탱크(43)의 상부에 배치되는 네 개의 흡수챔버(45)와, 상기 흡수챔버(45)를 연통시키는 이송덕트(47)와, 상기 흡수액(17)을 교반하기 위한 교반기를 포함한다.As shown, the wet absorption tower 41 having the multiple absorption chambers according to the present embodiment includes an absorbent liquid tank 43 containing the absorbent liquid 17 and four disposed above the absorbent liquid tank 43. The absorption chamber 45, the transfer duct 47 which communicates the said absorption chamber 45, and the stirrer for stirring the said absorption liquid 17 are included.

상기 흡수액탱크(43)는 그 내부에 흡수액(17)을 수용하는 콘테이너로서 일측에 공기주입구(55)를 갖는다. 상기 공기주입구(55)는 외부의 공기를 흡수액탱크(43) 내부로 유도하는 통로이다. 상기 공기주입구(55)를 통해 주입된 공기는 흡수액(17) 내부의 아황산칼슘을 석고로 산화시킨다.The absorbent liquid tank 43 has an air inlet 55 on one side as a container for accommodating the absorbent liquid 17 therein. The air inlet 55 is a passage for guiding outside air into the absorbent liquid tank 43. Air injected through the air inlet 55 oxidizes calcium sulfite in the absorbent liquid 17 to gypsum.

또한 상기 흡수액탱크(43)의 외부에는 펌프(25)가 구비된다. 상기 펌프(25)는 흡수액배출관(23)을 통해 흡수액탱크(43) 내부의 흡수액을 흡입하고 이를 흡수액공급관(29)을 통해 노즐(31)로 압송한다. 결국 상기 흡수액(17)은 펌프(25)에 의해 흡수액탱크(43) 외부로 배출된 후 노즐(31)로 보내어져 노즐(31)을 통해 분사되어 흡수액탱크(43)의 내부공간(43a)으로 되돌아온다. 아울러 상기한 바와같이 배출라인(27)을 통해 배출된 흡수액만큼의 소석회는 별도의 공급라인을 통해 흡수액탱크(43)로 보충된다.In addition, the pump 25 is provided outside the absorbent liquid tank 43. The pump 25 sucks the absorbent liquid in the absorbent liquid tank 43 through the absorbent liquid discharge pipe 23 and pumps it to the nozzle 31 through the absorbent liquid supply pipe 29. As a result, the absorbent liquid 17 is discharged to the outside of the absorbent liquid tank 43 by the pump 25 and then sent to the nozzle 31 and sprayed through the nozzle 31 to the internal space 43a of the absorbent liquid tank 43. Come back. As described above, the lime as much as the absorbent liquid discharged through the discharge line 27 is replenished into the absorbent liquid tank 43 through a separate supply line.

상기 샤프트(53)는 흡수액탱크(43)의 천장벽을 관통하지만, 흡수액(17)은 흡수액탱크(43)의 내부에 일정 범위내의 수위로 유지되므로 흡수액(17)이 외부로 누설될 염려는 없다. 상기 교반기의 기능은 도 1을 통해 설명한 교반기(19)와 동일하다.The shaft 53 penetrates the ceiling wall of the absorbent liquid tank 43, but since the absorbent liquid 17 is maintained at a level within a predetermined range inside the absorbent liquid tank 43, there is no fear that the absorbent liquid 17 will leak to the outside. . The function of the stirrer is the same as the stirrer 19 described through FIG.

한편, 상기 흡수챔버(45)는, 일정직경 및 높이를 갖는 원통형 케이스로서 그 하부가 개방되어 흡수액탱크(43)의 내부공간(43a)에 연통한다. 상기 흡수챔버(45)는 모터(49)의 주변에 대칭으로 배치된다. 특히 상기 흡수챔버(45)의 하단부는 흡수액탱크(43)의 내부로 하향 연장되어 흡수액(17)의 액면 하부에 위치해 잠긴다. 따라서 상기 노즐(31)로부터 분사된 흡수액은 흡수액탱크(43)로 귀환할 수 있고, 흡수챔버(45)를 통과하는 가스는 외부로 누설됨 없이 이송덕트(47)를 차례로 통과한다.On the other hand, the absorption chamber 45 is a cylindrical case having a constant diameter and height, the lower portion thereof is opened to communicate with the internal space 43a of the absorbent liquid tank 43. The absorption chamber 45 is disposed symmetrically around the motor 49. In particular, the lower end portion of the absorption chamber 45 extends downward into the absorption liquid tank 43 and is locked under the liquid surface of the absorption liquid 17. Therefore, the absorbent liquid injected from the nozzle 31 can be returned to the absorbent liquid tank 43, and the gas passing through the absorbing chamber 45 passes through the transfer duct 47 in sequence without leaking to the outside.

또한, 상기 각 흡수챔버(45)에는 가스유입구(45a)와 가스유출구(45b)가 구비된다. 상기 가스유입구(45a)는, 흡수챔버(45)의 (흡수탱크(43) 상부에 위치하는 부분의) 외주면 하측부에 위치하는 통로로서, 처리할 가스를 흡수챔버(45) 내부로 유도한다. 또한 가스유출구(45b)는 흡수챔버(45)의 외주면 상측부에 형성된 통로이며, 흡수챔버(45) 내부에서 처리된 처리가스를 외부로 배출하는 구멍이다.In addition, each absorption chamber 45 is provided with a gas inlet 45a and a gas outlet 45b. The gas inlet 45a is a passage located below the outer circumferential surface (of the portion located above the absorption tank 43) of the absorption chamber 45, and guides the gas to be processed into the absorption chamber 45. In addition, the gas outlet 45b is a passage formed in the upper portion of the outer circumferential surface of the absorption chamber 45 and is a hole for discharging the processing gas processed in the absorption chamber 45 to the outside.

상기한 각 흡수챔버(45)는 이송덕트(47)를 통해 상호 연통한다. 상기 이송덕트(47)는 흡수챔버(45)를 통과한 가스를 내부 유동시켜 다음 흡수챔버(45)로 이동시키는 도관이다. Each of the absorption chambers 45 communicates with each other through the transfer duct 47. The transfer duct 47 is a conduit for moving the gas passing through the absorption chamber 45 to the next absorption chamber 45.

상기 이송덕트(47)의 일단부는 임의의 흡수챔버(45)의 가스유출구(45b)에 연결되고 타단부는 이웃 흡수챔버(45)의 가스유입구(45a)에 연결된다. 따라서 도 3에 도시한 바와같이, 네 개의 흡수챔버(45)는 이송덕트(47)를 통해 직렬로 연통하며, 배기가스는 각 흡수챔버(45)의 하부로 유입하여 상향 유동한 후 상부로 빠져나간다.One end of the transfer duct 47 is connected to the gas outlet 45b of the arbitrary absorption chamber 45 and the other end is connected to the gas inlet 45a of the neighboring absorption chamber 45. Therefore, as shown in FIG. 3, the four absorption chambers 45 communicate in series through the transfer duct 47, and the exhaust gas flows upward through the lower portions of the absorption chambers 45 and flows upward. I'm going.

아울러 상기 각 흡수챔버(45)의 내부에는 다수의 노즐(31)이 설치된다. 상기 노즐(31)은 흡수액공급관(29)을 통해 공급된 흡수액을 처리공간(33)으로 하향 분출한다. 상기 노즐(31)로부터 분사되는 흡수액은, 해당 흡수챔버(45) 내에서 상향 유동하는 배기가스와 접하며, 배기가스 내부의 산화물을 흡수한 상태로 흡수액탱크(43)로 귀환한다.In addition, a plurality of nozzles 31 are installed in each of the absorption chambers 45. The nozzle 31 ejects the absorbent liquid supplied through the absorbent liquid supply pipe 29 downward into the processing space 33. The absorbing liquid injected from the nozzle 31 comes into contact with the exhaust gas flowing upward in the absorption chamber 45 and returns to the absorbing liquid tank 43 in the state of absorbing the oxide in the exhaust gas.

도면부호 57은 블로워이다. 상기 블로워(57)는 도 3의 도면상 우측 첫 번째 흡수챔버(45)의 가스유출구(45b)와 연결되며 처리가 완료된 가스를 외부로 뽑아내는 역할을 한다.Reference numeral 57 is a blower. The blower 57 is connected to the gas outlet 45b of the first absorption chamber 45 on the right side of FIG. 3, and serves to extract the processed gas to the outside.

상기한 구성을 갖는 본 실시예의 습식 흡수탑(41)의 작동은 다음과 같이 이루어진다.Operation of the wet absorption tower 41 of the present embodiment having the above configuration is made as follows.

먼저, 상기 펌프(25)를 구동하여 각 흡수챔버(45) 내부의 노즐(31)을 통해 흡수액(17)을 분사한다. 상기 노즐(31)로부터 분사되는 흡수액은 처리공간(33)을 지나 흡수액탱크(43)로 낙하한다. 또한 이와 동시에 모터(49)를 구동하여 흡수액탱크(43) 내부의 흡수액(17)을 계속적으로 교반해 흡수액(17)의 내부에 석고가 고형화하지 않도록 한다. 아울러 상기 공기주입구(55)를 통해 흡수액(17) 내부에 공기를 공급함으로써 흡수액 내부에 혼합되는 가령 아황산칼슘을 산화시킨다.First, the pump 25 is driven to spray the absorbing liquid 17 through the nozzles 31 inside the absorbing chambers 45. The absorbing liquid injected from the nozzle 31 passes through the processing space 33 and falls into the absorbing liquid tank 43. At the same time, the motor 49 is driven to continuously agitate the absorbent liquid 17 inside the absorbent liquid tank 43 so as to prevent gypsum from solidifying inside the absorbent liquid 17. In addition, by supplying air into the absorbent liquid 17 through the air inlet 55, for example, calcium sulfite mixed into the absorbent liquid is oxidized.

상기 흡수액(17)이 분사되고 있는 동안, 도면상 좌측 첫 번째 흡수챔버(45)의 가스유입구(45a)를 통해, 처리할 배기가스를 주입한다. 상기 가스유입구(45a)를 통해 주입된 배기가스는 처리공간(33)을 상향 유동한 후 가스유출구(45b)로 나가 이송덕트(47)를 통해 다음 흡수챔버(45)로 향한다. While the absorbing liquid 17 is being injected, the exhaust gas to be treated is injected through the gas inlet 45a of the first absorption chamber 45 on the left side of the drawing. The exhaust gas injected through the gas inlet 45a flows up the processing space 33 and then exits the gas outlet 45b to the next absorption chamber 45 through the transfer duct 47.

상기 배기가스가 처리공간(33)을 상향 유동하는 동안 노즐(31)로부터 분사된 흡수액과 접촉함은 물론이다. 상기 흡수액은 배기가스 내부의 산화물을 흡수한 상태로 낙하하여 흡수액탱크(43)로 모인다.It goes without saying that the exhaust gas comes into contact with the absorbing liquid injected from the nozzle 31 during the upward flow of the processing space 33. The absorbent liquid falls in the state in which the oxide in the exhaust gas is absorbed and is collected in the absorbent liquid tank 43.

상기와 같이 좌측 첫 번째 흡수챔버(45)와 이송덕트(47)를 통과한 배기가스는 두 번째 흡수챔버(45)와 세 번째 흡수챔버와 네 번째 흡수챔버를 차례로 통과하며 흡수액과 접한다. 상기 흡수챔버의 개수는 배기가스 중의 산성농도에 따라 조절 가능함은 물론이다. 특히 처리에 참여하는 흡수챔버의 개수에 따라 산성 가스의 처리효율을 조절할 수 있다.As described above, the exhaust gas passing through the left first absorption chamber 45 and the transfer duct 47 passes through the second absorption chamber 45, the third absorption chamber, and the fourth absorption chamber, and comes into contact with the absorption liquid. The number of the absorption chambers is, of course, can be adjusted according to the acid concentration in the exhaust gas. In particular, the treatment efficiency of the acidic gas can be adjusted according to the number of absorption chambers participating in the treatment.

상기 네 번째 마지막 흡수챔버(45)를 통과한 배기가스는 처리후 가스로서 블로워(57)를 통해 외부로 배기된다. 흡수챔버는 배기가스 중의 산성농도에 따라 The exhaust gas which has passed through the fourth last absorption chamber 45 is exhausted to the outside through the blower 57 as the treated gas. The absorption chamber depends on the acid concentration in the exhaust gas.

이상, 본 발명을 구체적인 실시예를 통하여 상세하게 설명하였으나, 본 발명은 상기 실시예에 한정하지 않고, 본 발명의 기술적 사상의 범위내에서 통상의 지식을 가진 자에 의하여 여러 가지 변형이 가능하다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
