이하, 본 발명에 따른 하나의 바람직한 실시 예를 첨부도면을 참조하여 상세히 설명한다. 본 발명에 따른 폐기물소각 비산재를 활용한 친환경 복토재 제조방법은; 도 1에 도시한 바와 같이, 제지슬러지소각재(10)와 하수슬러지소각재(20)와 레드머드슬러지(30)를 혼합 하여 고형분(40)을 제조하는 1차 혼합단계(S1)와; 상기 1차 혼합단계(S1)의 고형분(40)에 함수율 80~85%의 하수슬러지(50)를 혼합하는 2차혼합단계(S2)와; 상기 2차 혼합단계(S2)의 혼합물에 산성용액(60)을 분사하여 혼합하는 3차 혼합단계(S3)와; 상기 3차 혼합단계(S3)의 혼합물에 발생하는 반응열 및 수증기를 제거 시켜 흙과 동일한 형태의 복토재를 제조하는 양생단계(S4);를 포함하고 있다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. Eco-friendly cover material manufacturing method using waste incineration fly ash according to the present invention; As shown in FIG. 1, a primary mixing step (S1) of manufacturing a solid 40 by mixing the paper sludge incineration material 10, the sewage sludge incineration material 20, and the red mud sludge 30; A second mixing step (S2) of mixing the sewage sludge 50 having a water content of 80 to 85% with the solid content 40 of the first mixing step (S1); A third mixing step (S3) of spraying and mixing an acidic solution (60) to the mixture of the second mixing step (S2); It includes a curing step (S4) to remove the heat of reaction and steam generated in the mixture of the third mixing step (S3) to produce a cover material of the same form as the soil.
1차 혼합단계(S1)에서는 혼합기(믹서기)에 제지슬러지소각재(10)와 하수슬러지소각재(20)와 레드머드슬러지(30)를 60~45 : 30~45 : 5~15의 중량부로 혼합하는 단계이다. 먼저, 혼합기에 중량이 높은 제지슬러지소각재(10)를 먼저 넣고, 이에 하수슬러지소각재(20)와 레드머드슬러지(30)넣어 1~3분 동안 혼합하여 고형분(40)을 제조한다. In the first mixing step (S1) to mix the paper sludge incinerator (10), sewage sludge incinerator (20) and red mud sludge (30) to 60 to 45: 30 to 45: 5 to 15 parts by weight in a mixer (mixer) Step. First, a high weight paper sludge incineration material 10 is put into the mixer first, and the sewage sludge incineration material 20 and the red mud sludge 30 are put therein and mixed for 1 to 3 minutes to prepare a solid content 40.
이때 제지슬러지소각재(10)와 하수슬러지소각재(20)와 레드머드슬러지(30)를 60~45 : 30~45 : 10의 중량부로 혼합하는 이유는 강알카리성 분말인 제지슬러지소각재(10)만을 사용할시 3차 혼합단계(S3)에서 투입되는 가격이 비싼 산성용액(60)의 투입 중량이 중량부로 25~30 보다 많게되어 최종제조 복토재가 pH7~8.5의 안정화된 복토재가 제조됨으로 복토재 제조비용이 상승되기 때문이다. 그러므로 강알카리성 분말인 제지슬러지소각재(10)의 중량이 60~45일 때 강산성인 하수슬러지소각 재(20)를 30~45의 중량을 투입하여 줌으로써, 강알카리성 분말의 감소에 따라, 3차 혼합단계(S3)에서 투입되는 산성용액(60)의 투입 중량을 중량부로 10~20로 최소화 할 수 있기 때문이다.At this time, the reason for mixing the paper sludge incineration material (10), sewage sludge incineration material (20) and the red mud sludge (30) by 60 to 45: 30 to 45: 10 parts by weight is the use of paper alkaline sludge incinerator (10) which is a strong alkaline powder. When the input weight of the expensive acidic solution 60, which is charged in the third mixing step (S3), is more than 25 to 30 parts by weight, the final manufacturing cover material is manufactured to stabilize the cover material of pH 7 ~ 8.5, thereby increasing the cost of manufacturing the cover material. Because it becomes. Therefore, when the weight of the papermaking sludge incinerator 10, which is a strong alkaline powder, is 60 to 45, by adding 30 to 45 weight of the strong acid sewage sludge incinerator 20, the third mixture is reduced according to the decrease of the strong alkaline powder. This is because the input weight of the acidic solution 60 introduced in step S3 can be minimized to 10 to 20 parts by weight.
또한 제지슬러지소각재(10)의 중량이 중량부로 60~45이고 하수슬러지소각재(20)의 중량이 30~45인 이유는 pH 12~12.5 강알카리성인 제지슬러지소각재(10)의 투입 중량이 중량부로 60 이상이면 pH 3~4.5의 강산성 분말인 하수슬러지소각재(20)의 투입 중량이 중량부로 30 이하로 떨어져, 1차 혼합단계(S1)에서 제조되는 고형분(40)이 강알카리성 성분이 많아져, 3차 혼합단계(S3)에서 투입되는 산성용액(60)을 중량부로 10~20을 투입하여도 혼합물은 pH 10 이상이 되어 강한 암모니아가스가 발생되고, 최종 제조되는 복토재가 강알카리성이 되기 때문이다. 또한 pH 12~12.5의 강알카리성인 제지슬러지소각재(10)의 투입 중량이 중량부로 45 이하이면 pH 3~4.5의 강산성 분말인 하수슬러지소각재(20)의 투입 중량이 중량부로 45 이상이 되어, 1차 혼합단계(S1)에서 제조되는 고형분(40)의 성분중 산성분말이 많아져, 3차 혼합단계(S3)에서 투입되는 산성용액(60)을 중량부로 10~20을 투입하여도 강알카리성 분말의 감소에 따른 혼합물의 발열반응이 미약하여 하수슬러지의 수분제거효율이 떨어진다. 따라서 고형분(40)의 구성성분 중 제지슬러지소각재(10) 60~45 중량부와 하수슬러지소각재(20) 30~45 중량부를 혼합하는 것이 바람직하다.In addition, the weight of the paper sludge incineration material 10 is 60 to 45 parts by weight, and the weight of the sewage sludge incineration material 20 is 30 to 45. The weight of the paper sludge incineration material 10, which is pH 12 to 12.5, is strongly alkaline. If it is 60 or more, the input weight of the sewage sludge incinerator 20, which is a strong acid powder having a pH of 3 to 4.5, drops to 30 or less by weight, and the solid content 40 produced in the first mixing step (S1) increases the strong alkaline component. This is because even if 10 to 20 parts by weight of the acidic solution 60 introduced in the third mixing step (S3) is added at a pH of 10 or more, strong ammonia gas is generated, and the resulting cover material is strongly alkaline. . In addition, when the input weight of the strongly alkaline papermaking sludge incinerator 10 having a pH of 12 to 12.5 is 45 parts by weight or less, the input weight of the sewage sludge incinerator 20 which is a strong acid powder having a pH of 3 to 4.5 is 45 or more by weight, 1 Acidic powder of the components of the solid component 40 produced in the primary mixing step (S1) is increased, even if 10 to 20 parts by weight of the acid solution 60 is added in the third mixing step (S3) strong alkaline powder The exothermic reaction of the mixture due to the decrease of decreases the water removal efficiency of sewage sludge. Therefore, it is preferable to mix 60 to 45 parts by weight of the paper sludge incineration material 10 and 30 to 45 parts by weight of the sewage sludge incineration material 20 among the components of the solid component 40.
그리고 고형분(40)의 구성성분 중 황토색 탈수제인 레드머드슬러지(30)는 최종제조 복토재가 흙과 동일한 황토색을 갖기 위해 혼합하는 것이며, 이때 투입 중량이 중량부로 10인 이유는 레드머드슬러지(30)에도 50%의 함수율이 내포하고 있어 다량 투입될시 양생기간이 길어질 수 있기 때문이다. 따라서 최종 생산되는 복토재를 흙과 동일한 색상을 갖게 할 수 있는 최소의 중량인 10 중량부를 투입하는 것이 바람직하다.And the red mud sludge 30, which is an ocher color dehydrating agent, among the components of the solid component 40, is mixed in order to have the final manufactured cover material having the same yellow earth color as the soil. In this case, the input weight is 10 parts by weight in the red mud sludge 30. This is because the water content of 50% is also contained, and the curing period may be long when a large amount is added. Therefore, it is preferable to add 10 parts by weight, which is the minimum weight that can make the final produced cover material the same color as the soil.
1차 혼합단계(S1)에서 투입되는 제지슬러지소각재(10)의 대체 재료로는 pH 12~12.5이상의 강알카리성인 폐기물소각 비산재, 제철분진, 제강분진, 고로수쇄슬래그분말, 스테인레스 정련로 슬래그분말이 사용될 수 있으며, 레드머드슬러지(30)를 대체하여, 티타늄 제조과정 시 발생되는 폐석고, 황산제일철무수물, 황산제일철7수화물이 사용될 수 있다.Alternative materials for the paper sludge incineration material 10 introduced in the first mixing step (S1) include strong alkaline waste incineration fly ash having a pH of 12 to 12.5 or more, steel dust, steelmaking dust, blast furnace chain slag powder, and stainless smelting furnace slag powder. It can be used, in place of the red mud sludge 30, waste gypsum, ferrous sulfate anhydride, ferrous sulfate heptahydrate generated during the titanium manufacturing process can be used.
2차 혼합단계(S2)에서는 혼합기(믹서기)에 함수율 80~85%의 하수슬러지(50)와 상기 1차 혼합단계(S1)의 결과물인 고형분(40)을 100 : 40~60 중량부로 혼합하는 단계이다.In the second mixing step (S2) is 100: 40 to 60 parts by weight of the sewage sludge 50 having a water content of 80 to 85% and the solid content 40 as a result of the first mixing step (S1) in a mixer (mixer). Step.
먼저, 혼합기에 중량부가 높은 하수슬러지(50)를 먼저 넣고, 이에 고형분(40)을 넣어 1~3분간 혼합하는 단계이다. 즉 하수슬러지(50)의 함수율에 따라 하수슬러지(50) 100 중량부에 고형분(40) 40~60 중량부를 투입하여, 1차적으로 하수슬러지(50)의 함수율을 45~55% 으로 낮춰주는 단계이다.First, the sewage sludge 50 having a high weight part is first put into the mixer, and the solid content 40 is put therein and mixed for 1 to 3 minutes. That is, by putting 40 to 60 parts by weight of solids (40) in 100 parts by weight of sewage sludge (50) according to the water content of sewage sludge (50), firstly lowering the water content of sewage sludge (50) to 45 to 55%. to be.
이유는 3차혼합단계(S3)에서 산성용액(60) 10~20 중량부를 투입할시 화학적 발열반응에 의해 7~10%의 수분만이 제거되기 때문에 따라서 2차 혼합단계에서(S4)에서 하수슬러지(50)의 함수율을 최하 55%미만으로 낮추어 주어야 양생기간을 단축할 수 있기 때문이다. 이때 하수슬러지(50) 100 중량부에 고형분(40) 40~60 중량부로 혼합하는 이유는 고형분이 50 중량부 보다 적으면 하수슬러지(50)의 함수율이 80%일때 2차 혼합단계에서(S4) 혼합된 혼합물의 함수율은 55% 보다 많은 70~73% 함수율이 되어 양생시간이 길어지며, 또한 강알카리성 고형분(40) 60 중량부 보다 많으면, 3차 혼합단계(S3)에서 산성용액(60) 10~20 중량부를 투입하여도 혼합물은 pH 10 이상이 되어 강한 암모니아가스가 발생되고, 최종 생산되는 복토재가 강알카리성이 되기 때문이다.The reason is that when only 10 to 20 parts by weight of the acidic solution 60 is added in the third mixing step (S3), only 7 to 10% of the water is removed by the chemical exothermic reaction, thus, the sewage in the second mixing step (S4). This is because the curing time can be shortened by lowering the water content of the sludge to less than 55%. In this case, the reason for mixing 40 to 60 parts by weight of the solid content 40 to 60 parts by weight of the sewage sludge 50 is less than 50 parts by weight when the water content of the sewage sludge 50 is 80% in the second mixing step (S4). The water content of the mixed mixture is 70-73% water content of more than 55%, the curing time is long, and if more than 60 parts by weight of strong alkaline solids (40), the acidic solution (60) 10 in the third mixing step (S3) Even if ˜20 parts by weight is added, the mixture will have a pH of 10 or more, resulting in strong ammonia gas, and the resulting cover material will be strongly alkaline.
따라서 최소의 양생기간과 혼합물의 pH를 안정화시킬 수 있도록, 하수슬러지(50)와 상기 1차혼합단계(S1)의 고형분(40)을 100 : 40~60 중량부로 혼합하는 것이다.Therefore, in order to stabilize the minimum curing period and the pH of the mixture, the sewage sludge 50 and the solids 40 of the first mixing step (S1) is to mix 100: 40 to 60 parts by weight.
또한 2차 혼합단계(S2)에서 투입되는 하수슬러지(50)의 균등한 재료로는 음식물탈리액, 축산분뇨가 사용될 수 있다.In addition, as a uniform material of the sewage sludge 50 introduced in the secondary mixing step (S2), food desorption solution, livestock manure can be used.
3차 혼합단계(S3)에서는 상기 2차 혼합단계(S2)의 혼합물 140~160 중량부에 분사장치를 통해 산성용액(60) 10~20 중량부를 분사하며 혼합하는 단계이다. 즉 상기 2차 혼합단계(S2)의 혼합물이 담겨있는 혼합기(믹서기)를 계속 회전시키면서 이에 분사장치를 통해 산성용액(60) 10~20 중량을 믹싱되고 있는 2차 혼합단계(S2)의 혼합물 표면에 분사하여, 최대한 강알카리성 고형분(40)과 반응시키는 공정이다.In the third mixing step (S3) is a step of injecting and mixing 10 to 20 parts by weight of the acidic solution 60 through the injection device to 140 to 160 parts by weight of the mixture of the second mixing step (S2). In other words, while continuously rotating the mixer (mixer) containing the mixture of the secondary mixing step (S2) while mixing the surface of the mixture of the secondary mixing step (S2) 10 to 20 weight of the acid solution 60 through the injection device It is a process of spraying on and making it react with the strong alkaline solid content 40 as much as possible.
이유는 2차 혼합단계(S2)의 혼합물의 성분 중 강알카리성인 고형분(40)에 강산성인 산성용액(60)을 분사함으로써, 산성용액(60) H2SO4 가 고형분(40)의 주성분인 CaO, MgO, Al2O3등과 반응하여, CaSo4, MgSo4, Al2So4로 치환되어 고형제의 기능을 갖게 되고, 또한 강산과 강알카리에 의한 화학적 반응열로 인해 일부 하수슬러 지(50)내의 수분이 수증기로 증발되어, 하수슬러지(50)의 점성에 의해 응집된 2차 혼합단계(S2)의 혼합물은 3차 혼합단계(S3)거쳐, 점성에 의해 응집된 2차 혼합단계(S2)의 결과물은 수증기가 증발되어 함수율이 점차 떨어지므로 응집력이 줄어들어 잘게 부서진 입자상태가 된다.The reason is that by spraying a strongly acidic acid solution 60 to the strongly alkaline solids 40 of the components of the mixture of the second mixing step (S2), the acidic solution (60) H 2 SO 4 Reacts with CaO, MgO, Al 2 O 3, etc., which are the main components of the solid component 40, and is substituted with CaSo 4 , MgSo 4 , Al 2 So 4 to have the function of a solid agent, and also heat of chemical reaction by strong acid and strong alkali. Due to the water in some sewage sludge 50 is evaporated to water vapor, the mixture of the second mixing step (S2) agglomerated by the viscosity of the sewage sludge 50 is subjected to the third mixing step (S3), by the viscosity As a result of the aggregated secondary mixing step (S2), the water vapor is evaporated and the water content gradually decreases, so that the cohesive force is reduced to finely broken particles.
이때 산성용액(60)을 10~20 중량부를 투입하는 이유는 산성용액(60)이 중량부로 10 이하이면 혼합과정 중 암모니아 가스가 방출되며, 또한 최종생산물의 pH가 강알카리성이 된다.At this time, 10-20 parts by weight of the acidic solution 60 is the reason why the acidic solution 60 is 10 parts by weight or less ammonia gas is released during the mixing process, and the final product pH is strongly alkaline.
또한 산성용액(60)이 중량부로 20 보다 많이 투입되면, 최종생산물의 pH가 강산성이 되기 때문이다. 따라서 산성용액(60)은 고형분(40)의 구성성분 중 강알카리성인 제지슬러지소각재(10)의 중량부에 따라 제지슬러지소각재(10)의 중량부가 증가하면 산성용액(60)의 중량부도 증가되는 것이다. 그리고 3차 혼합단계(S3)에서 투입되는 산성용액(60)은 농도60~98%인 것을 사용하며, 산성용액(60)을 대체할 수 있는 균등물로는 인산, 질산, 불산, 염산이 사용될 수 있다.If the acid solution 60 is added in more than 20 parts by weight, the pH of the final product is strong acidity. Therefore, the acidic solution 60 may increase the weight part of the acidic solution 60 when the weight part of the paper sludge incinerator 10 increases according to the weight part of the strongly alkaline paper sludge incinerator 10 among the components of the solid component 40. will be. In addition, the acid solution 60 introduced in the third mixing step (S3) uses a concentration of 60 to 98%, and as an equivalent to replace the acid solution 60, phosphoric acid, nitric acid, hydrofluoric acid, hydrochloric acid may be used. Can be.
양생단계(S4)에서는 상기 3차 혼합단계(S3)의 혼합물에 발생하는 반응열과 수증기를 제거시켜 흙과 동일한 형태의 복토재를 제조하기 위하여 포크레인으로 뒤집어 주거나 또는 양생장치를 통하여 혼합물을 양생하는 단계이다.Curing step (S4) is the step of curing the mixture through the fork or inverted to the fork to produce a cover material of the same form as the soil by removing the heat of reaction and steam generated in the mixture of the third mixing step (S3) .
이유는 상기 3차 혼합단계(S3)에서 강산성과 강알카리성의 화학반응에 의해 혼합물의 내부는 섭씨 75~85도 까지 상승되며, 이로 인해 다량의 수분이 수증기로 증발된다. 따라서 포크레인으로 뒤집어 주거나 또는 양생장치를 통하여 혼합물의 내부에 발생되는 수증기를 뒤집기 또는 양생장치를 통하여 제거시켜 줌으로써, 양 생시간을 단축시킬 수 있기 때문이다.The reason is that in the third mixing step (S3) by the chemical reaction of strong acid and strong alkali, the inside of the mixture is raised to 75 ~ 85 degrees Celsius, which causes a large amount of water is evaporated into water vapor. Therefore, it is possible to shorten the curing time by inverting the forklift or removing water vapor generated inside the mixture through the curing device through the inverting or curing device.
발명의 기술을 정리하면 제지슬러지소각재(10)와 하수슬러지소각재(20)와 레드머드슬러지(30)를 60~45 : 30~45 : 5~15 의 중량부로 혼합된 결과물인 고형제(40)를 40~60 중량부를 함수율 80~85%의 하수슬러지(50) 100 중량부에 혼합하여, 1차적으로 함수율 80~85%인 하수슬러지(50)의 함수율을 45~55% 낮추어 주고, 이때 고형제의 구성성분 중 레드머드슬러지(30)에 의해 혼합물은 황토색으로 변화되며, 함수율 45~55%가 된 혼합물에 강산성인 산성용액(60)을 분사방식으로 10~20 중량부를 투입함으로써, 강산성인 산성용액(60) H2SO4 가 고형분(40)의 주성분인 CaO, MgO, Al2O3등과 반응하여, CaSo4, MgSo4, Al2So4로 치환되어, 고형제의 기능을 갖게 되고, 또한 강산성과 강알카리성에 의한 화학적 반응으로 인하여 혼합물은 섭씨 75~85도의 반응열이 발생되고 이로 인해 일부 하수슬러지(50)내의 수분이 수증기로 증발되고, 이때 하수슬러지(50)의 점성에 의해 응집된 2차 혼합단계(S2)의 혼합물은 3차 혼합단계(S3)거쳐, 점성에 의해 응집된 2차 혼합단계(S2)의 결과물은 수증기가 증발되어 함수율이 점차 떨어지므로 응집력이 줄어들어 잘게 부서진 입자상태가 된다. 이를 포크레인 또는 양생장치를 통해 혼합물의 반응열과 수분을 더 제거시켜 양생시킴으로써, 양생된 혼합물은 일정강도가 있는 흙과 동일한 형태의 복토재가 된다.To summarize the technique of the present invention, the resulting solid sludge (40) is a result of mixing the paper sludge incineration ash (10), sewage sludge incineration ash (20) and the red mud sludge (30) by 60 to 45: 30 to 45: 5 to 15 parts by weight. To 40 to 60 parts by weight of 100 parts by weight of sewage sludge (50) of water content of 80 to 85%, primarily to lower the water content of sewage sludge (50) of water content of 80 to 85% 45 to 55%, Among the components of the brothers, the mixture is changed to ocher color by the red mud sludge 30, and 10-20 parts by weight of a strongly acidic acid solution 60 is injected into the mixture having a water content of 45 to 55%, thereby making it strongly acidic. The acidic solution (60) H 2 SO 4 reacts with CaO, MgO, Al 2 O 3 and the like as the main component of the solid component 40, and is replaced with CaSo 4 , MgSo 4 , Al 2 So 4 , and has a solid function. In addition, due to the chemical reaction of strong acid and strong alkali, the mixture generates heat of reaction of 75 ~ 85 degrees Celsius, which causes some sewage sludge The water in the paper 50 is evaporated to water vapor, and the mixture of the secondary mixing step (S2), which is agglomerated by the viscosity of the sewage sludge 50, is subjected to the third mixing step (S3). The result of the mixing step (S2) is water vapor is evaporated gradually decreases the moisture content, so the cohesive force is reduced to finely broken particles. By curing this by further removing the heat of reaction and moisture of the mixture through a fork-lane or curing device, the cured mixture becomes a cover material of the same form as the soil having a certain strength.
