Description
본 발명은 터널형 콘베이어식 적외선 가열장치에 관한 것으로서, 특히 유무기계 피가열 물질에 대하여 가열특성이 우수한 4.5-15㎛ 대역의 원적외선을 고출력으로 균일하게 방사시키면서 방사파의 방향제어와 출력제어가 용이한 평판형의 적외선 히터의 구조와 구성재료를 최적화하고, 대면적의 피가열물을 비접촉식으로 급속, 균일하게 가열시킬 수 있는 터널형 콘베이어식 적외선 가열장치에 관한 것이다.The present invention relates to a tunnel-type conveyor infrared heater, in particular, easy to control the direction and output of the radiation wave while uniformly radiating far-infrared rays of 4.5-15 탆 band having high heating characteristics with respect to the material to be heated or not. The present invention relates to a tunnel-type conveyor infrared heater that can optimize the structure and constituent material of a flat-panel infrared heater and heat a large area of the heated object in a non-contact manner quickly and uniformly.
적외선(Infrared Ray, IR)은 전자기파이므로 직진성, 반사성, 투과성, 흡수성 등을 갖는다. 이와 같은 적외선은 기존의 전도나 대류와 같은 열전달 방식과는 전혀 다르게 중간 매질이 없이 피가열물에 광속으로 전달되고 직접 흡수되어 열로 전환되므로, 급속ㆍ균일하게 가열시키는 특징을 가지고 있다. 적외선을 가열원으로 사용할 경우 에너지 효율이 높고 전도나 대류 가열보다는 피가열물을 균일하게 가열시킬 수가 있어 고품질 제품의 대량생산이 가능하다. 특히 식품, 식약재, 섬유, 제지, 도료코팅/함침 등의 처리공정에서 가열기술의 중요성이 확대되고 있는데 피가열물질의 대부분이 천연 및 합성 고분자들이므로 원적외선 조사시 탁월한 가열특성을 보이는 것으로 확인되고 있다. Infrared Ray (IR) is an electromagnetic wave, so it has straightness, reflectivity, transparency, and absorption. Unlike the conventional conduction or heat transfer methods such as convection, the infrared rays have a characteristic of heating rapidly and uniformly because they are transferred to the light to be heated at the speed of light and are directly absorbed and converted into heat without an intermediate medium. When infrared is used as a heating source, the energy efficiency is high and the heated object can be uniformly heated rather than conduction or convection heating, enabling mass production of high quality products. In particular, the importance of heating technology is increasing in the food, food, textile, paper, paint coating / impregnation process. Since most of the material to be heated is natural and synthetic polymers, it has been confirmed to show excellent heating properties when irradiated with infrared rays. have.
그 동안 대면적 원적외선 방사체의 생체활성 및 난방용의 온열판넬에 대해서는 다수 출원되어 있으나 산업용의 고온 고출력 평면 방사체는 바인더, 고온방사체, 고온단열재, 전기절연재 등의 재료기술의 한계로 상업화가 되어 있지 않다. There have been many applications for thermal activity panels for bioactivity and heating of large area far infrared emitters, but industrial high-temperature, high-power flat radiators have not been commercialized due to the limitations of material technologies such as binders, high-temperature radiators, high-temperature insulation materials, and electrical insulation materials.
공개실용신안 1998-062687은 원적외선을 방사하는 온돌패널에 관한 것으로, 원적외선 방사용 세라믹 소재로 제조된 여러 개의 패널을 알루미늄이나 철판, 동판과 같은 금속판의 상부에 접착제를 이용하여 고정시켜 세라믹 온돌합판을 구성함으로써 돌침대 바닥부의 매트리스 등으로 사용할 수 있는 원적외선 방사 세라믹 온돌패널에 대하여 기술되어 있다. 등록실용신안 20-0152249는 면상 발열체에 소정의 방사재료를 코팅하여 가열시키는 원적외선 건조기에 관한 것으로, 다결정 주석, 세라믹, 석영유리 및 강화유리를 혼합하여 판상으로 응고시켜 면상체를 만들고, 그 뒷면에 실버 접착제로 전극이 형성되게 고정하여 발열시키는데 면상발열체가 무겁고 충격에 약해 대면적의 적외선 히터로 제작하는 것은 어려운 구조이다. Published Utility Model 1998-062687 relates to an ondol panel that emits far-infrared rays. A plurality of panels made of a far-infrared radiation ceramic material are fixed to the top of a metal plate such as aluminum, iron plate, or copper plate using an adhesive to fix the ceramic ondol plywood. The present invention describes a far-infrared radiation ceramic ondol panel that can be used as a mattress in a stone bed bottom. Utility Model No. 20-0152249 relates to a far-infrared dryer for heating a planar heating element by coating a predetermined radiating material, and mixing polycrystalline tin, ceramic, quartz glass and tempered glass to solidify it into a plate to make a planar body. It is difficult to manufacture with large area infrared heater because the surface heating element is heavy and weak against impact because it is fixed by forming silver electrode with silver adhesive.
원적외선 방사체는 세라믹이나 카본 흑체들이 사용되고 있는데 유기물질에의 흡수효율이 우수한 4.5-15㎛ 대역의 파장을 갖는 원적외선을 에너지 밀도가 높게 대량 방사시키기가 어렵다. 현재 적외선 가열설비로는 할로겐 램프, 적외선 방사재료가 코팅된 시즈히터, 세라믹 소결관, 저항발열선이 삽입된 세라믹 소결방사체 등이 상업화 되어 있으나 대량 방사 시에는 이들 모두 가열체의 표면온도가 500℃ 이상으로 고온이어서 근적외선 방사분율이 매우 높고 방사체의 표면이 둥근 파이프 형태이기 때문에 방사파의 방향제어가 불가능하며 단열재의 적용이 어려운 구조이므로 넓은 면적의 피가열물을 균일하게 가열시키는 고효율 전열설비 제작은 불가능하다.As far infrared emitters, ceramics or carbon black bodies are used, and it is difficult to radiate a large amount of far infrared rays with a high energy density with a wavelength of 4.5-15 占 퐉 having excellent absorption efficiency to organic materials. Currently, infrared heating facilities include halogen lamps, sheath heaters coated with infrared radiation materials, ceramic sintered tubes, ceramic sintered radiators with resistance heating wires, etc. Due to the high temperature, the near-infrared radiation fraction is very high and the surface of the radiator is round pipe shape, so it is impossible to control the direction of the radiation wave and it is difficult to apply the heat insulator. Do.
수분 건조, 발효숙성, 고분자 경화, 유기용매 휘발 등의 목적으로 사용되는 기존의 산업용 전열설비는 대부분 열풍대류방식으로 열전달 특성이 나빠 설비규모와 에너지 소모가 크고, 생산성이 낮으며 균일가열이 어려워 가열품질이 떨어지는 단점을 가지고 있다.Existing industrial heat transfer equipment used for moisture drying, fermentation maturation, polymer curing, volatilization of organic solvents, etc. is mostly hot air convection method, which has poor heat transfer characteristics, resulting in large scale and energy consumption, low productivity, and difficulty in uniform heating. It has the disadvantage of poor quality.

이상과 같은 구성을 갖는 본 발명의 터널형 콘베이어식 적외선 가열장치에 있어서, 장치가 정상적인 동작 상태하에서 피가열물(101)이 주몸체부(110) 내부로 들어오면, 상기 적외선 방사히터(120)(130)에 의해 적외선이 방사되어 피가열물(101)에 조사된다. 이때, 적외선 방사히터(120)(130)는 가열특성이 우수한 4.5-15㎛ 대역의 원적외선을 고출력(예를 들면, 소모전력 기준 5-50kW/㎡, 표면온도 기준 50∼500℃)으로 방사하여 주몸체부(110) 내부로 이동하는 피가열물(101)을 비접촉식으로 균일하게 가열하게 된다. 따라서, 대면적의 피가열물에 대한 비접촉식의 급속ㆍ균일 가열이 가능해 진다. In the tunnel-type conveyor infrared heater of the present invention having the configuration as described above, when the heating object 101 is introduced into the main body portion 110 in the normal operating state, the infrared radiation heater 120 Infrared rays are emitted by the 130 to irradiate the heated object 101. In this case, the infrared radiation heaters 120 and 130 radiate far infrared rays of 4.5-15 μm band having excellent heating characteristics at high power (for example, 5-50 kW / m 2 based on power consumption and 50 to 500 ° C. based on surface temperature). The heated object 101 moving inside the main body 110 is uniformly heated in a non-contact manner. Therefore, non-contact rapid and uniform heating to a large area to be heated is possible.
이상의 설명에서와 같이, 본 발명에 따른 터널형 콘베이어식 적외선 가열장치는 유무기계 피가열 물질에 대하여 가열특성이 우수한 4.5-15㎛ 대역의 원적외선을 고출력으로 균일하게 방사시키면서 방사파의 방향제어와 출력제어가 용이한 평판형의 적외선 히터의 구조를 가지고 있어, 전도와 대류가 에너지 전달수단인 기존의 가열설비에 비하여 장치의 크기를 1/2 이하로 축소시킬 수 있고, 에너지 소모량을 50% 이상 절감할 수 있으며, 생산성과 가열품질을 크게 향상시킬 수 있다.As described above, the tunnel-type conveyor infrared heater according to the present invention is a direction control and output of the radiation wave while uniformly radiating the far infrared rays of 4.5-15㎛ band having excellent heating characteristics with respect to the material to be heated or not With the structure of a flat type infrared heater, which can be easily controlled, the size of the device can be reduced to 1/2 or less compared to the existing heating facility where conduction and convection are energy transfer means, and energy consumption is reduced by 50% or more. It can greatly improve productivity and heating quality.
