본 고안은 농수산물 건조기의 폐열회수장치에 관한 것으로, 더욱 구체적으로는 농수산물 건조시 배풍구를 통해 외부로 빠져나가는 폐열을 핀튜브형태의 열교환기를 이용하여 흡입공기를 예열시켜 공급함으로서 에너지를 절감시켜 건조비용을 최소화할수 있도록 한 농수산물 건조기의 폐열회수장치에 관한 것이다.The present invention relates to a waste heat recovery device of agri-food dryer, and more specifically, to save energy by preheating and supplying the intake air by using a heat exchanger in the form of fin tube to exhaust waste heat to the outside through the vent when drying the agri-food. It relates to a waste heat recovery system for agricultural and marine products dryers to minimize costs.

일반적인 농수산물건조기는 건조실내부에 설치된 다단의 받침레일에 피건조물이 담겨진 채반을 재치시키고 일측의 열풍공급부에서 열풍을 건조실로 공급하여 건조한 다음 폐열의 일부는 열풍공급부로 보내지고 나머지는 배풍구를 통해 외부로 빠져나가게 된다.In general, the agricultural and marine product dryers place a table containing dried goods on a multi-stage supporting rail installed inside the drying chamber, supply hot air to the drying room from one side of the hot wind supply unit, and dry it, and then send a part of the waste heat to the hot air supply unit, and the rest is sent to the outside through the vent. To get out.

즉, 상기 농산물건조기의 열풍공급부는 버너 또는 전기히터 방식의 에너지원을 사용하여 외부에서 유입되는 공기를 가열하여 열풍을 발생시키게 되므로 열풍공급부로 유입되는 외부공기의 온도에 따라 소정온도의 열풍을 발생시키기 위한 에너지 소비량이 달라지게 된다.That is, the hot air supply unit of the agricultural product dryer generates a hot air by heating the air introduced from the outside using a burner or an electric heater energy source to generate hot air at a predetermined temperature according to the temperature of the external air introduced into the hot air supply unit. The energy consumption for this will be different.

그러나 종래에는 건조실내의 농수산물을 열풍에 의해 건조한 다음 폐열의 일부는 외부공기와 함께 열풍공급부로 보내지고 나머지는 배풍구를 통해 배출되기 때문에 에너지낭비가 많고 대기온도의 외부공기가 열풍공급부로 보내져서 열풍을 발생시키기 위해서는 많은 에너지를 필요로 하기 때문에 그만큼 농수산물 건조비용이 많이 들게 되어 농수산물의 경쟁력이 떨어지게 되는 문제점이 있었다.However, conventionally, the agricultural and aquatic products in the drying room are dried by hot air, and then a part of the waste heat is sent to the hot air supply unit along with the external air and the other part is discharged through the vents, which causes a lot of energy waste and external air at the atmospheric temperature is sent to the hot air supply unit. Since a large amount of energy is required to generate hot air, the cost of drying the agricultural and marine products is high, resulting in a drop in the competitiveness of agricultural and marine products.

본 고안은 이러한 문제점을 해결하기 위하여 농수산물 건조기의 배풍구를 통해 배출되는 폐열을 이용하여 열풍공급부로 흡입되는 외부공기를 예열공급하여 열풍을 발생시킬 수 있도록 한 폐열회수장치를 제공함에 있다.The present invention is to provide a waste heat recovery device that can generate hot air by preheating the external air sucked into the hot air supply unit by using the waste heat discharged through the exhaust port of the agricultural and marine products dryer to solve this problem.

본 고안은 송풍팬(26)으로 외부공기가 흡입구(22)를 통해 흡입되어 버너 및 전기히터등의 가열수단이 구비된 열풍공급부(20)에서 열풍을 발생시켜 건조실(10)로 보내지고 건조실(10)은 건조공간에 수직칸막이 형태로 구획된 다공부(14)가 형성된 수직통로(12)를 설치하고 양측 수직통로(12)외측에 다단으로 설치된 받침레일(16)에 채반(18)을 재치시켜 채반(18)에 담긴 피건조물을 열풍건조시키게 되고 건조실(10)상부일측은 열풍공급부(20)와 관통된 열풍순환구멍(28)이 형성되어 건조실(10)내의 외부폐열이 열풍중공부(20)로 보내지고 나머지 폐열은 배풍구(24)를 통해 외부로 배출시키는 농수산물 건조기로 되어 있다.The present invention is blown fan 26, the outside air is sucked through the inlet 22 to generate hot air from the hot air supply unit 20 is provided with a heating means such as a burner and electric heater to be sent to the drying chamber 10 and the drying chamber ( 10) is installed in the drying space in the vertical passage (12) formed with a porous portion 14 partitioned in the form of vertical partitions, and mounting the channel 18 on the support rail 16 installed in multiple stages on both sides of the vertical passage (12). Hot air is dried on the dry matter contained in the tray 18, and the upper side of the drying chamber 10 is formed with a hot air supply unit 20 and a hot air circulation hole 28 through which the external waste heat in the drying chamber 10 is hot air hollowed out ( 20) and the remaining waste heat is the agricultural and marine products dryer to be discharged to the outside through the vent (24).

본 고안은 상기 농수산물 건조기에서 배풍구(24)를 통해 배출되는 폐열을 이용하여 흡입구(22)를 통해 흡입되는 외부공기를 예열시켜 열풍공급부(20)로 공급하기 위한 폐열회수장치(30)로서, 폐열회수장치(30)는 배풍구(24)의 폐열이 지나가는 경로의 통체(32)내에 벌집형태로 배치된 다수의 연통관(34)이 소정길이로 설치되어 폐열이 연통관(34)을 거쳐 배출되는 과정에서 연통관(34)가열이 이루어지도록 하고 연통관(34)외주에 다수의 방열핀(36)이 등간격으로 설치되어 열교환효율을 높일 수 있게 하며 열풍공급부(20)에 공급되는 외부공기는 통체(32)일측의 흡입구(22)에서 연통관(34) 외벽 및 방열핀(36)을 거쳐 흡입되게 하여 외부공기가 열교환된 예열상태에서 개폐조절판(40)이 구비된 흡입안내구(42)를 통해 예열공기를 열풍공급부(20)로 보내지도록 되어 있다.The present invention is a waste heat recovery device 30 for supplying to the hot air supply unit 20 by preheating the outside air sucked through the inlet port 22 by using the waste heat discharged through the vent hole 24 in the agricultural and marine products dryer, Waste heat recovery device 30 is provided with a plurality of communication pipes 34 arranged in a honeycomb form in the cylinder 32 of the path through which the waste heat of the vent opening 24 passes through a predetermined length, so that the waste heat is discharged through the communication pipe 34. The communication tube 34 is heated in the process, and the plurality of heat dissipation fins 36 are installed at equal intervals on the outer side of the communication tube 34 to increase heat exchange efficiency, and the external air supplied to the hot air supply unit 20 is connected to the cylinder 32. The preheating air is provided through the suction guide port 42 having the opening and closing control plate 40 in the preheated state in which the external air is heat-exchanged by allowing the suction pipe 22 to be sucked through the communication pipe 34 and the heat dissipation fin 36 at one side. The hot air supply unit 20 is to be sent.

상기 통체(32)내의 연통관(34)길이방향에 등간격으로 선회안내벽(38)을 설치하여 외부공기가 선회되어 흡입될 수 있게 한 구성으로 외부공기의 흡입체류기간을 길게하고 예열이 골고루 이루어지도록 한 것을 더 포함한다.The turning guide wall 38 is installed at equal intervals in the direction of the communication tube 34 in the cylinder 32 so that the outside air can be sucked by turning the outside air, and the suction staying period of the outside air is made evenly and preheated. Includes more to lose.

이와 같이 된 본 고안의 농수산물 건조기는 피건조물이 담겨진 채반(18)을 건조실(10)내부의 받침레일(16)에 다단으로 재치시키고 열풍공급부(20)에서 공급되는 열풍에 의해 건조하게 되고 건조실(10)내의 일부 폐열은 열풍순환구멍(28)을 통해 열풍공급부(20)로 보내지고 나머지 폐열은 배풍구(24)를 통해 외부로 배출이 된다.In this way, the agricultural and marine products dryer of the present invention is placed in multiple stages on the support rail 16 inside the drying chamber 10 and dried by hot air supplied from the hot air supply unit 20. Some waste heat in 10) is sent to the hot air supply unit 20 through the hot air circulation hole 28 and the remaining waste heat is discharged to the outside through the vent hole (24).

본 고안에서는 상기 배풍구(24)를 통해 폐열이 외부로 배출될때 폐열회수장 치(30)에 의해 외부공기를 예열시켜 열풍공급부(20)로 공급할 수 있게 된다.In the present invention, when the waste heat is discharged to the outside through the vent hole 24, it is possible to preheat the outside air by the waste heat recovery device 30 to supply the hot air supply unit 20.

즉, 배풍구(24)로 빠져나가는 폐열이 통체(32)내에 다수설치된 소정길이의 연통관(34)을 거쳐 배출이 이루어지게 될때 연통관(34)을 가열하고 그 연통관(34)외주의 방열핀(36)에도 열이 발산되므로 그 발산되는 열에 의해 흡입구(22)를 통해 통체(32)내부의 연통관(34)외부와 방열핀(36)부분을 흡입되는 외부공기가 접촉가열하여 예열시키는 열교환이 이루어진 다음 열풍공급부(20)에 보내게 된다.That is, when the waste heat exiting the vent hole 24 is discharged through a communication tube 34 of a predetermined length installed in the cylinder 32, the communication tube 34 is heated and the heat dissipation fin 36 of the communication tube 34 outer periphery. Heat is also emitted, so that the heat generated by the heat dissipates through the inlet port 22 through the inlet 22 to communicate with the outside of the communication tube 34 and the outside air that is sucked into the heat dissipation fin 36. It is sent to the supply unit 20.

그래서, 열풍공급부(20)에서는 예열된 외부공기에 의해 적은 에너지를 사용하더라도 건조실(10)에 소정온도의 열풍을 발생시킬수 있게 되므로 종래의 농수산물 건조기에 비해 에너지 절감효과를 크게 높일 수 있게 된다.Therefore, the hot air supply unit 20 can generate hot air at a predetermined temperature in the drying chamber 10 even if a small amount of energy is used by the preheated external air, thereby greatly increasing the energy saving effect compared to the conventional agricultural and marine product dryers.

또한, 상기 통체(32)내에서 외부공기가 선회되어 열풍공급부(20)로 보내지도록 한 선회안내벽(38)을 설치한 경우에는 연통관(34)의 길이방향을 순차적으로 선회하면서 예열이 골고루 되고 체류기간이 길어지므로 예열효율을 한층 높일 수 있게 된다.In addition, when the turning guide wall 38 is installed so that the outside air is turned in the cylinder 32 to be sent to the hot air supply unit 20, the preheating is uniformly turned while sequentially turning the longitudinal direction of the communication pipe 34. The longer the residence period, the higher the preheating efficiency.

이상에서 본 고안은 상기 실시예를 참고하여 설명하였지만 본 고안의 기술사상범위내에서 다양한 변형실시가 가능함은 물론이다.Although the present invention has been described with reference to the above embodiment, various modifications are possible within the technical scope of the present invention.

이와 같이 본 고안의 농수산물 건조기의 폐열회수장치는 건조실에서 배풍구를 통해 배출되는 폐열을 이용하여 열풍공급부로 흡입되는 외부공기를 예열시켜 공 급하게 되므로 열풍공급부는 종래보다 훨씬 적은 에너지를 사용하여 건조실에 필요한 열풍을 발생할 수 있게 되어 에너지 절감효과가 크고 이에 따른 건조비용 최소화로 경쟁력을 크게 높일 수 있는 이점이 있다.Thus, the waste heat recovery device of the agricultural and marine product dryer of the present invention is supplied by preheating the outside air sucked into the hot air supply unit by using the waste heat discharged through the vent in the drying room, so the hot air supply unit uses much less energy than the conventional one. Since it is possible to generate the required hot air, the energy saving effect is large, and there is an advantage that can greatly increase the competitiveness by minimizing the drying cost.
