이하에 기술되는 내용은 단순히 본 발명과 관련되는 배경 정보만을 제공할 뿐 종래기술을 구성하는 것이 아니다.The information described below merely provides background information related to the present invention and does not constitute prior art.

피혁산업은 원료피를 가공 처리하여 가죽원단을 생산하는 제혁산업으로, 준비공정인 수적에서부터 최종 완성품의 도장공정까지 여러 가지 화학적 처리와 다양한 물리적 작용을 통해 의류, 신발, 가공 및 지갑, 벨트 등 일상 생활용품을 비롯한 자동차, 쇼파, 침대, 카페트 내장재에 이르기까지 관련 섬유/피혁제품을 생산하는 산업이다.The leather industry is a tanning industry that processes raw material hides to produce leather fabrics. From soaking as a preparation process to the painting process of the final finished product, various chemical treatments and various physical actions are used in daily life such as clothing, shoes, processing, and wallets and belts. It is an industry that produces related textile/leather products ranging from household items to automobiles, sofas, beds, and carpet interior materials.

피혁 제조 공정 중에 발생되는 고형 폐기물은 원료피 중량대비 50%수준이며, 특히 대부분 소각 또는 매립 처리로 인하여 환경적인 문제점을 유발시키고 있다.Solid waste generated during the leather manufacturing process is about 50% of the weight of the raw hide, and in particular, most of them are incinerated or landfilled, causing environmental problems.

피혁 공정에서 발생되는 폐기물은 위탁기관을 통해 별도 또는 공동 처리하는데 처리비용 부담이 높으며 소각 및 해양투기 처리 방법에 의해 연간 처리 비용이 300억원 규모에 다다르고 있는 실정이다. Wastes generated in the leather process are treated separately or jointly through consignment agencies, but the treatment cost burden is high, and the annual treatment cost is approaching 30 billion won due to incineration and ocean dumping treatment methods.

염색폐수슬러지는 섬유 제조시설 중에서 폐수 배출량이 가장 많으며, 폐수중의 오염물질 농도는 높은 편에 속한다. Dyeing wastewater sludge discharges the most wastewater among textile manufacturing facilities, and the concentration of pollutants in wastewater is high.

염색 원단은 먼저 호발, 정련, 표백공정을 통해 불순물이 제거된 후 염색 및 후처리 공정을 거친다. The dyed fabric is first subjected to dyeing and post-processing after impurities are removed through desizing, scouring, and bleaching processes.

호발, 정련, 표백 등 전처리 공정에서는 원단에 포함된 호제 및 처리 약품이 폐수에 포함되어 발생하며, 전체적으로 높은 온도, pH, 유기물 함량을 갖는다.In pretreatment processes such as desizing, scouring, and bleaching, sizing agents and treatment chemicals included in fabrics are included in wastewater and have high temperature, pH, and organic matter content as a whole.

원단가공 공정에 따라 다소 상이하나 전분 아크릴, 왁스 등이 주로 사용되기 때문에 이러한 성분이 폐수에 포함된다. 또한 염색공정 및 후처리 공정에서 염료, 염, 계면활성제 등이 포함된 폐수가 발생하며 슬러지에도 포함된다. Although it is somewhat different depending on the fabric processing process, since starch acrylic and wax are mainly used, these components are included in the wastewater. In addition, wastewater containing dyes, salts, surfactants, etc. is generated in the dyeing process and post-treatment process, and is included in the sludge.

염색산업의 폐수처리 공정에서는 응집공정의 화학 슬러지와 활성슬러지 공정의 잉여슬러지가 발생된다. 이러한 슬러지의 발생량은 폐수 응집제의 종류 및 사용량, 폐수공정의 운전 효율 등에 의해 결정된다. In the wastewater treatment process of the dyeing industry, chemical sludge from the flocculation process and surplus sludge from the activated sludge process are generated. The amount of sludge produced is determined by the type and amount of wastewater coagulant used, and the operating efficiency of the wastewater process.

국내 염색공단 전체에서 발생하고 있는 염색폐수슬러지는 약 270,000톤/년 이며 대부분 해역 배출을 하고 있다. The dyeing wastewater sludge generated in the entire domestic dyeing complex is about 270,000 tons/year, and most of it is discharged to the sea.

염색공단에서 발생하는 슬러지는 폐수의 처리 방법에 따라 2종류로 분류되며, 화학적 처리법에 의해 폐수처리 한 후 발생한 슬러지는 화학슬러지, 미생물 처리법에 의해 발생한 슬러지를 미생물 슬러지로 분류되어진다.The sludge generated in the dyeing complex is classified into two types according to the wastewater treatment method, and the sludge generated after wastewater treatment by chemical treatment is classified as chemical sludge, and the sludge generated by microbial treatment is classified as microbial sludge.

한편, 전 세계적으로 대부분 폐기물을 35%는 땅 및 바다, 산 등에 매립한다. On the other hand, 35% of most waste worldwide is landfilled in land, sea, and mountains.

이중 폐기물의 15~20%는 재활용 및 퇴비화를 통해 회수되거나 소각된다.Of these, 15-20% of waste is recovered through recycling and composting or incinerated.

국내에 슬러지 및 폐기물은 매립비용만으로 대략 14~23만원/Ton대로 염색업체들의 기업 운영에 대한 영향을 주고 있다. 또한, 악취발생 등 민원으로 인해 반입을 전면불허 하면서 매립으로 비용이 2배 이상 상승할 것으로 보여 진다.Sludge and waste in Korea affect the business operation of dyeing companies at approximately 140,000 ~ 230,000 won / ton with landfill costs alone. In addition, it is expected that the cost will more than double due to landfilling, while importation is completely prohibited due to civil complaints such as odor.

염색 및 피혁슬러지 등을 활용하여 연료를 만들거나 에너지화를 하는 다양한 기술이 있다. There are various technologies for making fuel or energy using dyeing and leather sludge.

이러한 기술 중 대표적으로는 슬러지를 건조하는 기술방법과 두 번째로는 탄화 및 반탄화 공정 방법이 있으며, 마지막으로는 수열탄화 공정기술이 있다. Among these technologies, there is a method of drying sludge, a carbonization and torrefaction process method secondly, and a hydrothermal carbonization process technology.

건조하는 기술방법으로 처리하는 경우, 예비 건조기에서 나염, 섬유 및 피혁슬러지는 함수율을 약 84%(Max)에서 함수율 75%까지 건조 후 열풍 건조기에서 탄화에 필요한 함수율인 15%까지 되도록 한다. In the case of processing by the drying technique, the moisture content of printing, fiber and leather sludge in the preliminary dryer is dried from about 84% (Max) to 75%, and then dried in a hot air dryer to 15%, which is the moisture content required for carbonization.

또한 염색산업은 염료를 원료로 하여 피염물에 화학적, 물리화학적 반응을 통해 빛의 선택 흡수 성능을 장기적으로 남아 있게 함으로써 색을 나타내게 하는 산업이다. In addition, the dyeing industry is an industry that uses dyes as raw materials to show colors by maintaining the selective absorption of light for a long period of time through chemical and physicochemical reactions in dyed materials.

염색 가공공정에서 발생되는 오염물질은 염색 과정의 염료를 비롯하여 염료의 분산 상태를 유지시켜주기 위한 계면활성제, 염료의 염착 효율을 높이기 위한 캐리어 용매와 기타 호발, 정련, 표백, 감량 공정에서 발생하는 유기성 오염물질이 있으며, 생산 규모에 비하여 용수 사용이 많아 폐수 발생이 많고 오염물질의 부하가 높아 대표적 악성폐수슬러지로 분류된다. Contaminants generated in the dyeing process include the dye in the dyeing process, a surfactant to maintain the dispersion of the dye, a carrier solvent to increase the dyeing efficiency, and other organic substances generated in the desizing, scouring, bleaching, and weight loss processes. There are pollutants, and the use of water is high compared to the production scale, so wastewater is generated and the load of pollutants is high, so it is classified as a representative malignant wastewater sludge.

현재 국내에서의 염색 및 피혁슬러지 처리방법은 해양투기 및 토양매립으로 처리되어지고 있다. 특히 피혁슬러지를 소각처리 할 경우 폐기물 내에 포함되어 있는 화학물질로 변질될 우려가 많아 소각방법으로는 처리가 곤란하다. Currently, dyeing and leather sludge treatment methods in Korea are being treated by ocean dumping and soil reclamation. In particular, when leather sludge is incinerated, it is difficult to treat it by incineration because there is a high risk of deterioration into chemicals contained in waste.

현재 pilot plant수준의 설비로 피혁 및 염색슬러지 활용에 대해 기초시험하고 있으며, 수열탄화설비를 국내의 염색 및 피혁슬러지 처리방법으로 적용을 시도하고 있다. Currently, basic tests are being conducted on the use of leather and dyed sludge with facilities at the pilot plant level, and hydrothermal carbonization facilities are being tried as domestic dyeing and leather sludge treatment methods.

따라서 섬유, 나염, 피혁공정에서의 발생되는 오염물질을 최소화하는 청정생산기법의 도입과 화학 및 생물학적 폐수처리공정에서의 오염물질을 줄이는 기술개발과 아울러 발생된 폐기물을 친환경적으로 무해화하고 재활용이 가능하도록 경제적으로 처리 처분하는 기술개발이 필요하다.Therefore, it is possible to introduce clean production techniques that minimize pollutants generated in textile, printing, and leather processes, develop technology to reduce pollutants in chemical and biological wastewater treatment processes, and harmlessly and recycle generated wastes in an eco-friendly way. It is necessary to develop technology to treat and dispose of waste economically.

먼저, 분쇄기(10)는 피혁, 섬유, 나염 슬러지; 및 목질계 성분;을 1mm~30mm 크기로 분쇄하여 원료로 공급한다(S210).First, the crusher 10 is leather, fiber, printing sludge; and wood-based components; are pulverized into a size of 1 mm to 30 mm and supplied as raw materials (S210).

그리고 나서, 분쇄기(10)는 상기 분쇄된 원료를 촉매 및 물과 혼합하여 수열탄화조(20)에 공급한다(S220).Then, the grinder 10 mixes the pulverized raw material with a catalyst and water and supplies it to the hydrothermal carbonization tank 20 (S220).

수열탄화조(20)는 상기 물과 혼합된 원료를 산소를 차단하고 교반기가 갖추어진 반응로 안에서 온도 180-260℃, 압력 10-35bar, 총수분량은 70-80%를 유지하여 1-4시간 동안 수열탄화 반응시킨다(S230).The hydrothermal carbonization tank 20 blocks oxygen from the raw material mixed with the water and maintains a temperature of 180-260 ° C, a pressure of 10-35 bar, and a total water content of 70-80% in a reactor equipped with an agitator for 1-4 hours. During the hydrothermal carbonization reaction (S230).

다음, 고액 분리기(30)는 상기 수열탄화 공정에서 생성되는 고형 연료의 수분을 분리한다(S240). 여기서 분리된 수분인 용수는 촉매와 함께 다시 분쇄기(10)로 피드백 된다. 필요에 따라 용수 및 촉매 공급기가 사용될 수 있다 Next, the solid-liquid separator 30 separates moisture from the solid fuel generated in the hydrothermal carbonization process (S240). Water, which is the moisture separated here, is fed back to the grinder 10 together with the catalyst. Water and catalyst feeders can be used as needed

그리고 나서, 펠렛 제조기(50)는 상기 건조된 고형 연료의 분말을 펠렛 형태의 고형연료로 만든다(S260).Then, the pellet maker 50 makes the powder of the dried solid fuel into a solid fuel in the form of pellets (S260).

상기 과정에서 수열탄화조(20)의 역할을 좀 더 상세히 설명하면 다음과 같다.The role of the hydrothermal carbonization tank 20 in the above process will be described in more detail as follows.

물은 온도와 압력에 따라 형태가 변화하는 특징을 가지는데 180~260℃, 10~50bar에서 임계점을 가진다. 임계점 이상의 온도와 압력 범위에서는 초임계로 고온, 고압의 짙은 수증기 형태를 보인다. 아임계수는 물의 임계온도 이상, 임계압력 이하의 고온 중압의 증기 형태와 물의 임계온도 이하 및 포화 증기압 이상의 중온 중압의 물을 뜻한다. Water has a characteristic of changing its shape depending on temperature and pressure, and has a critical point at 180 ~ 260 ℃ and 10 ~ 50 bar. In the temperature and pressure range above the critical point, it is supercritical and shows the form of high-temperature, high-pressure, dense water vapor. Subcritical water refers to high-temperature and medium-pressure steam above the critical temperature of water and below the critical pressure, and medium-temperature and medium-pressure water below the critical temperature of water and above the saturated vapor pressure.

아임계수를 사용하기 위해서 고온고압의 조건이 동반된다. 이 방식은 보통 190℃ 이상에서 적용되며 아임계수를 사용하기 위하여 충분히 높은 기압과 무산소 조건에서 진행된다. In order to use subcritical water, conditions of high temperature and high pressure are accompanied. This method is usually applied at 190 ° C or higher and proceeds under sufficiently high air pressure and anoxic conditions to use subcritical water.

반응시간에 대한 많은 연구들이 진행되어 왔으며, 그 시간은 60초부터 10시간에 이르기까지 다양하지만 20~30분 정도에서 반응이 일어나는 것으로 연구되었다. 특히, 산 또는 염기성 물질을 추가하는 것도 생성물 형성에 영향을 미친다. 물은 반응물과 용매로써 작용하는데, 운전 조건에 따라서 다른 물리적·화학적 특성을 나타낸다. Many studies on the reaction time have been conducted, and the time varies from 60 seconds to 10 hours, but it has been studied that the reaction occurs in about 20 to 30 minutes. In particular, adding an acid or basic substance also affects product formation. Water acts as both a reactant and a solvent, and exhibits different physical and chemical properties depending on operating conditions.

본 발명의 실시예에서의 수열탄화조(20)에서는 180~260℃ 온도의 물은 이온성이 최대가 되어서 산과 염기로 작용하게 된다. 반응시간에 대한 많은 연구들이 진행되어 왔으며, 그 시간은 12~24시간까지 이르기까지 다양하지만 30분내에도 반응이 일어난다. 또한, 산(Acid) 또는 염기성 물질을 추가하는 것도 생성물 형성에 영향을 미친다. 또한, 물의 유전율이 감소하게 되어 비극성 용매와 같은 반응을 보인다. In the hydrothermal carbonization tank 20 in the embodiment of the present invention, water at a temperature of 180 to 260 ° C has maximum ionicity and acts as an acid and a base. Many studies on the reaction time have been conducted, and the time varies from 12 to 24 hours, but the reaction occurs within 30 minutes. In addition, adding an acid or basic substance also affects product formation. In addition, the dielectric constant of water is reduced, so it reacts like a non-polar solvent.

또한, 수열탄화조(20)의 하이브리드 수열탄화를 통해 생성된 고형연료제조는 평형함수율이 낮아져 저장과정에서 부패할 가능성을 낮출 수 있다. In addition, the solid fuel produced through hybrid hydrothermal carbonization of the hydrothermal carbonization tank 20 has a lowered equilibrium moisture content, thereby reducing the possibility of decay during storage.

고형연료는 파쇄성이 좋아져서 가스화로나 발전소에서 사용할 수 있는 그린펠릿성형 형태로 제조가 가능해진다. 동시에 무 촉매 반응보다 발열량과 수율을 증가시켜주고 공정온도와 시간을 줄여줄 수 있다.Solid fuel has improved crushability and can be manufactured in the form of green pellets that can be used in gasifiers or power plants. At the same time, the calorific value and yield can be increased and the process temperature and time can be reduced compared to non-catalytic reactions.

또한, 수열탄화조(20)의 탄화공정기술은 탄화부에 중점을 두어 건조시간, 건조성능, 건조기(40) 드럼의 회전수, 탄화물 이송 스크루의 속도, 탄화시간 등의 설계 요소를 검토하여 안정적인 시스템 다단형식의 탄화관을 거쳐서 탄화되도록 한다. In addition, the carbonization process technology of the hydrothermal carbonization tank 20 focuses on the carbonization part and examines design factors such as drying time, drying performance, rotational speed of the drum of the dryer 40, speed of the carbide transfer screw, and carbonization time to ensure stable The system is carbonized through a multi-stage carbonization tube.

탄화기는 보조 연료의 공급에 의해서 탄화에 필요한 열원을 공급하도록 한다. The carbonizer supplies a heat source necessary for carbonization by supplying an auxiliary fuel.

특히, 본 발명의 하이브리드 수열탄화 공정은 수열탄화조(20)에서 두 가지 이상의 바이오매스 및 유기성폐기물을 혼합하고 적정 촉매를 적용하여 HTC 공정을 수행하는 기술로서 발열량을 최대 40% 까지 높여주며 원하지 않는 유해 물질을 줄여서 환경 친화적인 연료를 만들어 준다. In particular, the hybrid hydrothermal carbonization process of the present invention is a technology of performing the HTC process by mixing two or more types of biomass and organic waste in the hydrothermal carbonization tank 20 and applying an appropriate catalyst, increasing the calorific value by up to 40% and eliminating unwanted It reduces harmful substances and makes environmentally friendly fuel.

또한, 촉매를 적용한 Hybrid HTC 기술은 반응 중에 적정한 촉매를 사용하여 발열반응인 탈복실화과정을 약화시켜 급격히 온도와 압력이 상승하는 것을 막아주고, 수열탄화반응 중 발생되는 이산화탄소를 감소시켜 고분자 성상을 유지하게 하여 별도의 접합제 없이 성형이 가능하고 동시에 수율도 높여 줄 수 있다. In addition, Hybrid HTC technology with a catalyst uses an appropriate catalyst during the reaction to weaken the deboxylation process, which is an exothermic reaction, to prevent a rapid increase in temperature and pressure, and to maintain polymer properties by reducing carbon dioxide generated during the hydrothermal carbonization reaction. By doing so, it is possible to mold without a separate binder and at the same time increase the yield.

본 발명에서는 촉매를 사용한 Hybrid HTC 반응과 무촉매 수열탄화(HTC) 반응과 비교하여 온도는 10~30℃가 감소하고 공정압력은 0.8~2.8MPa 내려가며 반응시간은 최대 3시간 정도 단축될 수 있다. In the present invention, compared to the Hybrid HTC reaction using a catalyst and the non-catalytic hydrothermal carbonization (HTC) reaction, the temperature is reduced by 10 ~ 30 ℃, the process pressure is reduced by 0.8 ~ 2.8 MPa, and the reaction time can be shortened by up to 3 hours. .

또한, 무촉매 수열 반응(HTC)으로 생성된 차르와 달리 Hybrid HTC 촉매 반응은 리그닌의 고분자특성을 그대로 유지하여 반응 후 접착력을 유지하고 있으며 수율도 최대 20% 더 높게 얻을 수 있다. In addition, unlike char produced by non-catalytic hydrothermal reaction (HTC), Hybrid HTC catalysis maintains the polymeric properties of lignin and maintains adhesive strength after reaction, and yields up to 20% higher can be obtained.

본 발명의 실시예에서는 피혁 및 나염, 섬유 슬러지를 하이브리드 수열탄화기술로 사전 예비 시운전을 수행하였으며 설비 운전의 조건은 탄화 온도 200℃, 220℃, 240℃의 변화, 함수율 각각 80% 변화, 각 운전 조건 변화에 따른 발열량 및 수율분석을 실시하였다.In the embodiment of the present invention, leather, textile printing, and fiber sludge were subjected to preliminary trial runs using hybrid hydrothermal carbonization technology, and the conditions for facility operation were carbonization temperature of 200 ° C, 220 ° C, and 240 ° C, respectively, 80% change in moisture content, each operation Calorific value and yield analysis were conducted according to the change in conditions.

수열탄화조(20)의 반응기 온도 220℃ 조건을 최적 조건으로 도출되어 운전을 수행하였다. 운전 수행 시 발생되는 안정적인 처리 및 환경성 분석을 위해서 자가 측정 및 공인기관 측정을 동시에 수행하였다.The reactor temperature of 220° C. of the hydrothermal carbonization tank 20 was derived as the optimum condition, and operation was performed. Self-measurement and measurement by an authorized agency were performed simultaneously for stable treatment and environmental analysis that occur during driving.
