Description

RDF(고형연료)를 활용한 연속식 소각보일러{RDF(Refuse Derived Fuel) for continuative furnace boiler}Refuse Derived Fuel (RDF) for continuative furnace boiler}

본 발명은 산업폐기물 및 일반폐기물 중에 가연성폐기물(폐플라스틱, 폐섬유, 폐타이어, 폐종이, 폐목재, 유분, 가축부산물 등)을 선별공정, 파쇄공정, 건조공정, 화학약품처리공정, 성형공정을 거쳐 생산된 RDF(Refuse Derived Fuel)고형연료를 궁극적 목적인 연소실의 연소효과를 극대화하여 환경기준치 이하의 오염 배가스를 저감하는데 목적이 있으며 이로 인하여 발생되어지는 폐열 또는 온수는 농어촌 또는 산업용보일러에 구조결합하여 대체에너지로 사용하는데 목적이 있다.The present invention is the combustible waste (waste plastic, waste fiber, waste tire, waste paper, waste wood, oil, animal by-products, etc.) sorting process, crushing process, drying process, chemical treatment process, molding process among industrial waste and general waste It aims to reduce pollutant exhaust gas below environmental standard value by maximizing the combustion effect of the combustion chamber, which is the ultimate purpose of RDF (Refuse Derived Fuel) solid fuel produced through wastewater, and the generated waste heat or hot water is structurally combined with farming and fishing villages or industrial boilers. The purpose is to use as alternative energy.

본 고안은 화격자 축로방식이 아닌 선별처리된 RDF(고형연료)를 연속투입방식의 와류형 고온 소각기를 개발하여 배가스중의 오염물질의 주범인 NOx, SOx, Co, Cl. Dioxin 등을 완전 해결할 수 있는 고온 와류형 소각기 인 것이다. 한편 우리나라에서는 일차산업에서 없어서는 안될 에너지원인 화석연료의 궁핍으로 전반적인 대체에너지가 필요한 즈음 가연성폐기물을 매립 또는 소각에만 의존하고 있는 이때에 소형 RDF 전용 소각보일러를 개발하여 산업용 또는 농어촌 에너지로 활용하게 되면 그 재원은 약 5,000억원의 에너지 절감효과를 가져올 수 있다.The present inventors developed a vortex-type high-temperature incinerator of continuous RDF (solid fuel) instead of grate shaft system, which is the main culprit of NOx, SOx, Co, Cl. It is a high temperature vortex type incinerator that can completely solve Dioxin. On the other hand, in Korea, when there is a lack of fossil fuel, which is an indispensable energy source in the primary industry, relying only on landfill or incineration for combustible wastes when overall alternative energy is needed, small RDF incineration boilers are developed and used as industrial or rural fishing energy. Financial resources can bring about energy savings of about 500 billion won.

본 발명 RDF 전용소각보일러는 산업폐기물 또는 일반폐기물에서 배출되어지는 가연성폐기물을 전반적으로 양질의 RDF(고형연료)를 생산하여 연소효과를 극대화 할 수 있도록 구성된 RDF 전용보일러 인 것이다.The RDF incinerator for the present invention is an RDF exclusive boiler configured to maximize the combustion effect by producing high quality RDF (solid fuel) from the combustible waste discharged from industrial waste or general waste.

상기와 같은 RDF(고형연료)의 가장 큰 장점은 연속적 소각 보일러에 정량공급할 수 있도록 RDF 의 규격이 정해진 원료로써 고 칼로리의 열량으로 미국의 RDF 규격 ASTM #5 또는 4.500Kcal 이상의 열량을 가진 고형연료로써 환경기준치 이하로 배가스 중의 오염물질을 배출할 수 있도록 구성되어진 것이다. 본 발명의 핵심 기술인 와류형 소각기는 연소실에 연소공기의 공급을 극대화 할 수 있고 연속식 연료투입장치로 일정량의 연료를 투입 후 에는 자동으로 연소 후 연소된 재는 자동 배출 될 수 있도록 구성되어진 것이다. 또한 상부2차연소실[4]과 하부1차 연소실[5] 은 일정한 간격으로 이격되어 있어 연소시 미연소된 건류가스에 연소공기의 공급을 극대화 할 수 있도록 되어 있어 고온(1100℃ 이상)으로 완전연소에 가깝게 연소시킬 수 있도록 하였다. 또한 연소실에 공급되는 연소공기는 원통형 중간공기차단내통[3]과 외통[2]의 사이 공간을 지나 송풍기[14]에 흡입되기 때문에 1차적으로 예열(80℃이상)이 이루어지고 다시 원통형 중간공기차단내통[3] 과 1차연소실 내통[5] 및 상부 2차연소실 내통[4] 사이의 공간으로 송풍기[14]에 의하여 고온의 공기가 중간공기차단내통[3]의 내주면에 접선으로 공급되어 와류를 형성하여 가열(200℃이상)되어 연소실에 공급되므로 고온의 연소가 가능하도록 하였다.The biggest advantage of RDF (solid fuel) is that the raw material of the RDF standard is determined to supply quantitatively to continuous incineration boilers. It is configured to discharge pollutants in flue gas below environmental standard value. The vortex type incinerator, which is the core technology of the present invention, is capable of maximizing the supply of combustion air to the combustion chamber and is configured to automatically discharge the combusted ash after combustion automatically after inputting a certain amount of fuel into the continuous fuel input device. In addition, the upper secondary combustion chamber [4] and the lower primary combustion chamber [5] are spaced at regular intervals to maximize the supply of combustion air to the unburned dry gas during combustion. It can be burned close to combustion. In addition, since the combustion air supplied to the combustion chamber is sucked into the blower [14] through the space between the cylindrical intermediate air blocking inner cylinder [3] and the outer cylinder [2], the preheating (80 ° C. or more) is performed first, and then the cylindrical intermediate air again. Hot air is tangentially supplied to the inner circumferential surface of the intermediate air cut-off cylinder [3] by the blower [14] into the space between the shut-off cylinder [3] and the primary combustion chamber inner cylinder [5] and the upper secondary combustion chamber inner cylinder [4]. The vortex was formed and heated (more than 200 ° C.) to be supplied to the combustion chamber to enable high temperature combustion.

Vortex air generated by the combustion air supply port [15] and the blower [14] tangentially installed in the intermediate air shut-off cylinder [3] and the combustion chamber air supply [12] and the primary combustion chamber inner cylinder [5] and the upper secondary combustion chamber The fuel is supplied with combustion air to the fuel while turning and descending along the inner circumferential surface of the lower primary combustion chamber inner cylinder [5] through a spaced space between the inner cylinders [4] and combusted in the lower primary combustion chamber [1A-5]. The unburned gas is concentrated and concentrated in the center of the lower primary combustion chamber [5], and the unburned gas is spaced at regular intervals between the primary combustion chamber [5] and the upper secondary combustion chamber [4]. The combustion gas is supplied again from the combustion air and secondary combustion occurs. The combustion gas reaching the combustion gas retention delay plate [9] installed in the upper secondary combustion chamber inner cylinder [4] lowers the discharge rate, thereby increasing combustion efficiency and increasing combustion again. The gas is the phase of the intermediate air The unburned exhaust gas is combusted close to complete combustion by receiving combustion air supplied through the vortex protrusion 8 and the reburn air supply air inlet 7 installed in the bed.

연소공기 흡입구[6]로부터 흡수되어지는 공기는 중간공기차단내통[3]을 통하여 200∼300℃로 예열되어 Hot air 흡입구[17], Hot air 흡입배관[16]을 통하여 하부1차연소실내통[5]에 고온의 공기를 공급하는 과정으로 이루어져 있다. 이때 연소실내의 핵심기술인 [4],[5] 상부2차연소실내통과 하부1차연소실내통의 간격을 공기량 및 압력에 준하여 일정간격으로 이격시켜 공기의 분산속도를 조절할수 있고 분산된 Hot air는 하부1차연소실 내통[5]에 타공된 연소실 공기 급기구[12]를 통하여 로스톨[13]방향으로 일정량의 공기를 불어 넣어 주어 상부에서의 회전와류식 공기와 하층부위에서의 공기공급이 원활하게 등배분 되어 연소실 내부의 연소를 원활하게 하는 동시에 연소시간이 빨라져 고온(1100∼1300℃)을 유지하면서 연속적으로 소각보일러의 물 또는 폐열을 이용하고자 하는 보일러 및 열풍건조를 원만하게 할 수 있는 연속식 RDF(고형연료)전용소각보일러인 것이다.The air absorbed from the combustion air intake [6] is preheated to 200-300 ° C. through the intermediate air cut-off cylinder [3], and is connected to the lower primary combustion chamber through the hot air intake [17] and the hot air intake pipe [16]. 5] is the process of supplying hot air.
