Description

고농도 액상 유해가스 제거제{Highly concentrated liquid eliminator for removing harmful gases}Highly concentrated liquid eliminator for removing harmful gases

본 발명은 고농도 액상 유해가스 제거제에 관한 것으로서, 보다 상세하게는 중탄산나트륨 분말, 분산제 및 물을 특정 비율로 혼합하여 액체상태 또는 액상으로의 유지가 가능하도록 한 고농도 액상 유해가스 제거제에 관한 것이다.The present invention relates to a high concentration liquid hazardous gas removal agent, and more particularly, to a high concentration liquid hazardous gas removal agent in which sodium bicarbonate powder, a dispersant, and water are mixed in a specific ratio to maintain a liquid state or a liquid state.

일반적으로 소각로에서 연소시 발생되는 배가스 내에는 염화수소(HCl), 황산화물(SOx) 등과 같은 유해물질이 포함되어 있는데, 이러한 유해물질은 국내외적으로 발생되는 초미세먼지의 원인물질로 알려지면서 배출기준이 강화되고 있다.In general, harmful substances such as hydrogen chloride (HCl) and sulfur oxides (SOx) are contained in the flue gas generated during combustion in incinerators, and these harmful substances are known as the causative substances of ultrafine dust generated domestically and internationally. This is being strengthened.

종래에는 도 1에 도시된 바와 같이, 일측에 배가스가 유입되는 가스유입구(300)가 형성된 본체(100)와 본체(100) 내측 상부에 설치되어 본체(100) 내부로 액상소석회를 분사하는 분사노즐(200)을 포함하는 준건식 세정기내에서 액상소석회와 배가스 내에 포함된 유해물질을 중화반응시키고, 중화반응에 의해 생성된 고체상의 분진은 하부에 형성된 분진호퍼(400)로 수집하여 분진배출구(500)를 통해 분진박스(미도시)로 배출하고, 비산재가 포함된 수증기 등은 비산재를 필터링 한 후, 분진호퍼(400)의 측부에 설치된 가스배출구(700)를 통해 배출되도록 하고 있다.Conventionally, as shown in FIG. 1, a main body 100 having a gas inlet 300 through which exhaust gas flows in, and an injection nozzle installed on the inner upper part of the main body 100 to inject liquid slaked lime into the main body 100 In the semi-dry scrubber including 200, the liquid sintered lime and the harmful substances contained in the exhaust gas are neutralized, and the solid dust generated by the neutralization reaction is collected by the dust hopper 400 formed at the lower part, and the dust discharge port 500 ) Through a dust box (not shown), and after filtering the fly ash, the steam containing fly ash is discharged through the gas outlet 700 installed on the side of the dust hopper 400.

그러나, 액상소석회를 이용하는 종래방식은 고체상의 분진과 비산재가 잔여물로 발생되는데, 지정폐기물인 비산재의 경우 매립장에서 처리하는 것이 의무화되어 있어 매립장에서 처리하고 있으나 최근 매립비용이 급상승함에 따라 해당 업계에서는 비산재 처리가 큰 과제로 대두되고 있다.However, in the conventional method using liquid slaked lime, solid dust and fly ash are generated as residues.Fly ash, which is a designated waste, is obligated to be disposed of at the landfill. Fly ash treatment has emerged as a major issue.

이러한 이유로 최근에는 아래 반응식 1 및 반응식 2와 같이, 중탄산나트륨(NaHCO3)과 염화수소(HCl), 황산화물(SOx) 등의 유해물질을 반응시켜 고체상 염을 형성하여 집진설비를 통해여 제거함으로써, 지정폐기물인 비산재가 발생되지 않도록 하고 있다.For this reason, recently, as shown in Scheme 1 and Scheme 2 below , by reacting harmful substances such as sodium bicarbonate (NaHCO 3 ) and hydrogen chloride (HCl) and sulfur oxide (SOx) to form a solid salt and remove it through a dust collector, Fly ash, which is a designated waste, is not to be generated.

NaHCO3 + HCl = NaCl + CO2 + H2O <반응식 1>NaHCO 3 + HCl = NaCl + CO 2 + H 2 O <Scheme 1>

NaHCO3 + SO2 + 1/2O2 = NaSO4 + 2CO2 + H2O <반응식 2>NaHCO 3 + SO 2 + 1/2O 2 = NaSO 4 + 2CO 2 + H 2 O <Scheme 2>

한편, 중탄산나트륨은 통상 건식 세정기를 이용하여 분말형태로 분사하는 방식을 사용해 왔는데, 분말형태의 중탄산나트륨은 유해가스와의 반응성이 낮아 처리효율이 낮을 뿐 아니라, 건식 세정기를 통해 균일한 공급이 어려워 유해가스와 지속적이면서 균일하게 반응시키기가 어려워 유해가스의 처리효율을 일정하게 유지할 수 없는 문제점이 발생한다.On the other hand, sodium bicarbonate has generally been sprayed in powder form using a dry scrubber, but powdered sodium bicarbonate has low reactivity with noxious gases and thus has low processing efficiency, and it is difficult to uniformly supply it through a dry scrubber. It is difficult to continuously and uniformly react with the harmful gas, so that the treatment efficiency of the harmful gas cannot be constantly maintained.

또한, 낮은 반응성으로 인해 많은 양을 투입해야 하므로 그에 따른 비용이 크게 증가하는 문제점이 발생한다.In addition, because of the low reactivity, a large amount must be added, so that the cost is greatly increased.

위와 같은 이유로 중탄산나트륨의 높은 반응성과 균일한 공급을 위하여, 물과 중탄산나트륨을 혼합한 액상의 유해가스 제거제를 사용하는 방안이 제안되어 있으나, 중탄산나트륨의 경우 쉽게 경화되는 문제가 있어 혼합물의 액상 유지가 어려운 문제점이 있다.For the above reasons, for the high reactivity and uniform supply of sodium bicarbonate, a method of using a liquid noxious gas remover in which water and sodium bicarbonate are mixed has been proposed, but sodium bicarbonate has a problem that it is easily hardened, so the liquid phase of the mixture is maintained. There is a difficult problem.

이로 인해 기존에는 필요량 보다 적은 양의 중탄산나트륨 분말을 물과 혼합하여 중탄산나트륨 혼합물이 액상을 유지할 수 있도록 하고 있다.For this reason, conventionally, sodium bicarbonate powder in an amount smaller than the required amount is mixed with water so that the sodium bicarbonate mixture can maintain a liquid phase.

그러나, 위와 같이 중탄산나트륨의 함량이 낮은 중탄산나트륨 혼합물의 경우 거래처에 납품 시 보다 많은 양을 운반해야 하므로 물류비용이 상승할 뿐 아니라 낮은 반응성으로 인해 유해가스 중화효율이 떨어져 상당히 많은 양을 투입해야 하는 문제점이 발생한다.However, in the case of sodium bicarbonate mixtures with a low sodium bicarbonate content as above, logistics costs are increased because more quantities must be transported when delivered to the customer, and due to low reactivity, the neutralization efficiency of harmful gases decreases, so considerably large amounts must be added. A problem arises.

한국등록실용 제20-0236725호Korean Registered Office No. 20-0236725

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 중탄산나트륨 분말, 분산제 및 물을 특정 비율로 혼합하여 액상태의 유지가 가능하도록 한 고농도 액상 유해가스 제거제를 제공함에 있다.The present invention has been conceived to solve the above problems, and an object of the present invention is to provide a high-concentration liquid noxious gas removal agent capable of maintaining a liquid state by mixing sodium bicarbonate powder, a dispersant, and water in a specific ratio. .

상기 목적을 달성하기 위한 본 발명에 따르면, 중탄산나트륨 분말 20~60 중량부와, 분산제 5~15 중량부와, 잔량으로서 물을 혼합하여 제조되는 것을 특징으로 하는 고농도 액상 유해가스 제거제가 제공된다.According to the present invention for achieving the above object, a high concentration liquid harmful gas remover is provided, characterized in that it is prepared by mixing 20 to 60 parts by weight of sodium bicarbonate powder, 5 to 15 parts by weight of a dispersant, and water as a balance.

여기서, 상기 분산제는 가성소다 수용액, 알루미나 수용액 및 염산 수용액 중 선택된 어느 하나인 것을 특징으로 한다.Here, the dispersant is characterized in that any one selected from an aqueous solution of caustic soda, an aqueous alumina solution, and an aqueous hydrochloric acid solution.

그리고, 상기 분산제는 50% 가성수다 수용액, 20% 알루미나 수용액 및 15% 염산 수용액 중 선택된 어느 하나인 것을 특징으로 한다.In addition, the dispersant is characterized in that any one selected from a 50% aqueous solution of caustic water, a 20% aqueous alumina solution, and a 15% aqueous hydrochloric acid solution.

또한, 상기 분산제의 함량이 15 중량부인 것을 특징으로 한다.In addition, it is characterized in that the content of the dispersant is 15 parts by weight.

상기와 같은 본 발명에 의하면, 중탄산나트륨 분말, 분산제 및 물을 특정 비율로 혼합하여 장시간 액상 유지가 가능한 고농도 액상 유해가스 제거제가 제공됨에 따라 종래 분말 형태로 제공되는 유해가스 제거제에 비해 유해가스와의 반응성이 높아져 유해가스의 처리효율이 크게 향상된다.According to the present invention as described above, a high concentration liquid harmful gas remover capable of maintaining a liquid for a long time by mixing sodium bicarbonate powder, a dispersant, and water in a specific ratio is provided. As the reactivity is increased, the processing efficiency of harmful gases is greatly improved.

또한, 분말 형태의 유해가스 제거제에 비해 균일한 공급이 가능하므로 유해가스와 지속적이면서 균일하게 반응시킬 수 있어 유해가스의 처리효율을 균일하게 유지할 수 있게 된다.In addition, since it is possible to supply evenly compared to the noxious gas removing agent in the form of powder, it is possible to continuously and uniformly react with the noxious gas, thereby maintaining the treatment efficiency of the noxious gas uniformly.

아울러, 분말 형태의 유해가스 제거제에 비해 유해가스와의 반응성이 높아 보다 적은 양으로도 유해가스의 처리가 가능하므로 유해가스의 중화처리 비용을 크게 절감할 수 있게 된다.In addition, since the reactivity with the toxic gas is higher than that of the powdered toxic gas removing agent, the toxic gas can be treated with a smaller amount, so that the cost of neutralizing the toxic gas can be greatly reduced.

도 1은 종래 액상소석회를 이용한 유해가스 처리과정을 설명하기 위한 도면.1 is a view for explaining a process of treating harmful gases using a conventional liquid slaked lime.

이하에서는 도면을 참조하여 본 발명을 보다 상세하게 설명한다. 도면들 중 동일한 구성요소들은 가능한 어느 곳에서든지 동일한 부호들로 나타내고 있음에 유의해야 한다. 또한 발명의 요지를 불필요하게 흐릴 수 있는 공지기능 및 구성에 대한 상세한 설명은 생략한다.Hereinafter, the present invention will be described in more detail with reference to the drawings. It should be noted that the same components in the drawings are denoted by the same reference numerals wherever possible. In addition, detailed descriptions of known functions and configurations that may unnecessarily obscure the subject matter of the invention will be omitted.

본 출원인은 중탄산나트륨, 분산제 및 물을 특정 비율로 혼합하면 종래와 달리 중탄산나트륨 혼합물의 경화현상이 늦춰져 액상 유지가 가능하다는 것을 발견하게 되었으며, 이러한 중탄산나트륨 혼합물의 특징적인 비율은 하기에서 보다 구체적으로 설명한다.The applicant of the present invention has found that mixing sodium bicarbonate, a dispersant, and water in a specific ratio slows the hardening phenomenon of the sodium bicarbonate mixture, unlike the prior art, and allows the liquid to be maintained.The characteristic ratio of the sodium bicarbonate mixture is described in more detail below. Explain.

본 발명의 일 실시예에 따른 고농도 액상 유해가스 제거제는 중탄산나트륨 분말 20~60 중량부와, 분산제 5~15 중량부와, 잔량으로서 물을 혼합하여 제조되는 것을 특징으로 한다.The high concentration liquid hazardous gas remover according to an embodiment of the present invention is characterized in that it is prepared by mixing 20 to 60 parts by weight of sodium bicarbonate powder, 5 to 15 parts by weight of a dispersant, and water as a balance.

중탄산나트륨 분말은 염화수소(HCl), 황산화물(SOx) 등의 유해물질과 반응하여 고체상 염을 형성함으로써, 유해가스를 중화시키는 역할을 하는 주요물질이다.Sodium bicarbonate powder is a major substance that plays a role of neutralizing harmful gases by reacting with harmful substances such as hydrogen chloride (HCl) and sulfur oxides (SOx) to form solid salts.

여기서, 중탄산나트륨 분말의 함량이 20 중량부 미만이면 유해가스의 중화효과가 낮아지는 문제가 발생되고, 60 중량부를 초과하면 자체 응집력에 의해 덩어리지는 문제가 발생될 뿐 아니라 분산제 및 물의 함량을 상대적으로 감소시켜 액상태의 중탄산나트륨 혼합물을 생성하기 어려운 문제가 발생할 수 있으므로 20~60 중량부가 사용되는 것이 바람직하다.Here, if the content of the sodium bicarbonate powder is less than 20 parts by weight, the neutralizing effect of the harmful gas is lowered, and if it exceeds 60 parts by weight, not only the problem of lumping due to self-cohesiveness occurs, but also the content of the dispersant and water is relatively reduced. It is preferable to use 20 to 60 parts by weight since it may be difficult to produce a liquid sodium bicarbonate mixture by reducing it.

분산제는 중탄산나트륨 분말과 물의 혼합 과정에서 중탄산나트륨 분발이 골고루 분산되어 물과 함께 혼합되도록 하는 역할을 한다.The dispersant plays a role in allowing the sodium bicarbonate powder to be evenly dispersed and mixed with water in the process of mixing the sodium bicarbonate powder and water.

이러한 분산제는 50% 가성소다 수용액, 20% 알루미나 수용액 및 15% 염산 수용액 중 선택된 어느 하나가 사용될 수 있다.This dispersant may be any one selected from a 50% aqueous caustic soda solution, a 20% aqueous alumina solution, and a 15% aqueous hydrochloric acid solution.

여기서, 분산제의 함량이 5 중량부 미만이면, 혼합 과정에서 중탄산나트륨 분말을 골고루 분산시키는 효과를 발휘하지 못하는 문제가 발생되고, 15 중량부를 초과하면, 상대적으로 물 함량이 감소되어 액상태의 중탄산나트륨 혼합물을 생성하기 어려운 문제가 발생될 수 있으므로 5~15 중량부가 사용되는 것이 바람직하다.Here, if the content of the dispersant is less than 5 parts by weight, the problem of not exerting the effect of evenly dispersing the sodium bicarbonate powder in the mixing process occurs, and if it exceeds 15 parts by weight, the water content is relatively reduced, resulting in a liquid sodium bicarbonate. It is preferable to use 5 to 15 parts by weight because it may cause a difficult problem to form a mixture.

전술한 바와 같이, 본 발명의 일 실시예에 따라 제조되는 고농도 액상 유해가스 제거제는 중탄산나트륨 분말, 분산제 및 물을 특정 비율로 혼합함에 따라 장시간 액상 유지가 가능한 중탄산나트륨 혼합물을 제공할 수 있다.As described above, the high-concentration liquid hazardous gas remover prepared according to an embodiment of the present invention may provide a sodium bicarbonate mixture capable of maintaining a liquid for a long time by mixing sodium bicarbonate powder, a dispersant, and water in a specific ratio.

이에 따라 분말 형태의 중탄산나트륨에 비해 유해가스와의 반응성이 높아 유해가스의 처리효율이 크게 향상될 뿐 아니라 적은 양으로도 유해가스의 처리가 가능하므로 유해가스의 중화처리 비용을 크게 절감할 수 있게 된다.Accordingly, the reactivity with harmful gas is higher than that of sodium bicarbonate in powder form, so not only the treatment efficiency of harmful gas is greatly improved, but also the treatment of harmful gas is possible with a small amount, so that the cost of neutralization treatment of harmful gas can be greatly reduced. do.

또한, 액상을 유지할 수 있어 분말 형태의 중탄산나트륨에 비해 균일한 공급이 가능하므로 유해가스와 지속적이면서 균일하게 반응시킬 수 있어 유해가스의 처리효율을 균일하게 유지할 수 있게 된다.In addition, since it is possible to maintain a liquid phase, a uniform supply is possible compared to sodium bicarbonate in powder form, so that the harmful gas can be reacted continuously and uniformly, so that the processing efficiency of the harmful gas can be uniformly maintained.

이하에서는 본 발명의 일실시예에 따라 제조된 고농도 액상 유해가스 제거제와, 분산제를 첨가하지 않고 제조된 유해가스 제거제의 점도측정을 통해 액상태의 유지여부를 비교해 보았다.Hereinafter, a high concentration liquid hazardous gas remover prepared according to an embodiment of the present invention and a hazardous gas remover prepared without adding a dispersant were compared to maintain a liquid state through viscosity measurement.

상기와 같이 제조된 실시예 1 내지 실시예 3과 비교예로 제조된 유해가스 제거제의 액상태의 유지여부를 비교하기 위해 LV2(62)스핀들이 장착된 브룩필드 점도계를 이용하여 3rpm의 속도로 5분간 회전시키는 방식으로 제조직후와 24시간 정치후의 점도를 측정하였다.In order to compare the maintenance of the liquid state of the harmful gas remover prepared in Examples 1 to 3 and Comparative Example prepared as described above, a Brookfield viscometer equipped with an LV2 (62) spindle was used at a speed of 3 rpm. The viscosity was measured immediately after preparation and after standing for 24 hours by rotating for minutes.

여기서, 10,000cp 이상은 점도가 측정되지 않는 경화 상태이며, 측정된 점도는 하기 표 1과 같다.Here, 10,000 cp or more is a cured state in which the viscosity is not measured, and the measured viscosity is shown in Table 1 below.

<표 1><Table 1>

Figure 112019125939799-pat00001
Figure 112019125939799-pat00001

상기 표 1을 참조하면, 실시예 1 ~ 9 각각은 점도가 10,000cp 이하로 제조 후 24시간 경과한 시점에서도 점도 측정이 가능한 액상이 유지되는 것을 확인하였다.Referring to Table 1, each of Examples 1 to 9 had a viscosity of 10,000 cp or less, and it was confirmed that a liquid phase capable of measuring viscosity was maintained even after 24 hours after preparation.

그에 반해, 분산제를 투입하지 않고, 중탄산나트륨 분말 60 중량부와 물을 혼합하여 제조된 비교예의 경우, 점도가 10,000cp 이상으로 측정이 불가한 경화 상태임을 확인하였다.On the other hand, in the case of the comparative example prepared by mixing 60 parts by weight of sodium bicarbonate powder and water without adding a dispersant, it was confirmed that the viscosity was 10,000 cp or more, which was impossible to measure.

위와 같은 결과를 볼 때, 본 발명의 일 실시예에 따라 제조된 고농도 액상 유해가스 제거제는 중탄산나트륨의 액상태의 유지가 가능하도록 한 기술임을 알 수 있다.From the above results, it can be seen that the high-concentration liquid hazardous gas remover prepared according to an embodiment of the present invention is a technology capable of maintaining the liquid state of sodium bicarbonate.

아울러, 제조 직후의 측정 점도와 24시간 정치 후의 측정 점도의 차이가 분산제의 함량이 낮을수록 큰 것을 볼 때, 분산제의 함량이 높을수록 점도가 상승하는 폭이 낮아 고농도 액상 유해가스 제거제의 액상태가 오랫동안 유지될 수 있음을 확인하였다.In addition, when it is seen that the difference between the measured viscosity immediately after preparation and the measured viscosity after standing for 24 hours is larger as the content of the dispersant is lower, the higher the content of the dispersant, the lower the extent of the increase in viscosity. It was confirmed that it can be maintained for a long time.

또한, 50% 가성소다 수용액의 경우, 분산제의 함량이 변화되더라도 각각의 제조 직후 점도에 큰 차이가 없고, 24시 정치 후의 점도 상승 폭이 낮은 것으로 나타나 다른 분산제에 비해 고농도 액상 유해가스 제거제의 액상태를 보다 오랫동안 유지할 수 있는 것으로 확인되었다.In addition, in the case of 50% caustic soda aqueous solution, even if the content of the dispersant is changed, there is no significant difference in viscosity immediately after each preparation, and the increase in viscosity after standing at 24 hours is low, compared to other dispersants. It was confirmed that it can be maintained for a longer time.

비록 본 발명이 상기 바람직한 실시 예들과 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정이나 변형을 하는 것이 가능하다. 따라서, 첨부된 특허 청구범위는 본 발명의 요지에 속하는 이러한 수정이나 변형을 포함할 것이다.Although the present invention has been described in connection with the above preferred embodiments, it is possible to make various modifications or variations without departing from the gist and scope of the invention. Accordingly, the appended claims will cover such modifications or variations that fall within the gist of the present invention.
