본 고안은 엽연초 건조기의 폐열회수장치에 관한 것이다.The present invention relates to a waste heat recovery device of the leaf tobacco dryer.

통상의 엽연초 건조기는 소정 넓이의 엽연초 건조실 일측에 버어너등의 가열수단을 갖는 열교환로 및 송풍기가 적층설치된 열교환실이 부설되어 송풍기를 통해 흡입되는 외부공기가 열교환로를 거치면서 열풍화된 후, 엽연초 건조실과 열교환로 사이의 판넬 하부측에 형성된 통풍구를 통해 엽연초 건조실로 유입되도록 함으로서, 건조실내에서 엽연초 건조처리공정이 진행되도록 되어 있다.In the conventional leaf tobacco dryer, a heat exchange furnace having a heating means such as a burner and a heat exchanger chamber in which a blower is stacked are installed on one side of a leaf tobacco dry chamber having a predetermined width, and the outside air sucked through the blower is hot-aired through the heat exchange passage. The leaf tobacco drying chamber is introduced into the leaf tobacco drying chamber through an air vent formed at the lower side of the panel between the leaf tobacco drying chamber and the heat exchange path.

이와 같은 종래 엽연초 건조기에 있어서, 열교환실(1)에서의 열교환 과정은, 상측의 흡기구(2) 하방에 위치되는 송풍기(3)에 의해 흡입되는 외부공기가 하향유입되면서 버어너등의 가열수단을 통해 가열된 상태인 하방의 열교환로(4)에 부딪쳐 열풍화되도록 되어 있다.In such a conventional tobacco leaf dryer, the heat exchange process in the heat exchange chamber (1), while the outside air sucked by the blower (3) located below the upper inlet (2) flows downward, and the heating means such as burner It hits the heat exchange path 4 below in the state heated by heat, and is made to hot-air.

이와같은 열교환작용과정에 있어서는, 특정가열수단을 통해 발생되는 열량이 열교환로(4) 내부를 거치면서 열교환된 후, 잔여열량은 열교환로(4) 상부측의 배기관(5)을 통해 대기중에 그대로 방출되도록 되어 있었으며, 이때 방출되는 배기열량의 자체온도가 약 300℃ 이상의 고온을 유지하고 있게 됨에 따라 상대적으로 열교환율이 매우 저하될 수 밖에 없었음은 물론 연료 소모율은 매우 높게 되면서 에너지 활용의 측면에서 볼때 바람직하지 못한 결과를 초래하고 있었고, 또한 버어너 등 특정가열수단의 가동시간이 상대적으로 늘어나 자체 수명이 단축되는 등의 폐단까지 야기되고 있었던 것이다.In this heat exchange process, after the heat generated through the specific heating means is heat-exchanged while passing through the heat exchange furnace 4, the remaining heat is left in the atmosphere through the exhaust pipe 5 on the upper side of the heat exchange furnace 4. In this case, the heat exchange rate of the exhaust gas was maintained at a high temperature of about 300 ° C. or higher, and the heat exchange rate was inevitably lowered, and the fuel consumption rate was very high. In view of this, it was causing undesired results, and also caused a discontinuity such as shortening of its own life due to relatively increased uptime of a specific heating means such as a burner.

본 고안은 이와같은 현재의 문제점을 감안하여 이를 효과적으로 해소하고자 안출된 것으로, 열전도율이 우수한 다수의 방열관을 1쌍의 집열통 사이에 연결하여 보조열교환기를 이루고 상기 열교환기를 상측의 흡기구와 송풍기 사이에 게재시킴과 동시에 열교환로와 배기구 사이를 연결하는 배기관을 1쌍의 집열통에 각각 연결설치하여 대기중으로 방출되는 폐열량이 다수의 방열관을 통해 송풍기 상측부위에서 재발산되면서 흡입공기를 예비가열토록 하는 단순원리의 폐열회수장치를 제공함으로서, 열효율의 극대화 효과 및 연료 소모율의 최소화 효과를 공히 얻도록 하는데 주목적이 있는 것인바, 그 구성 및 그에 따른 작용효과를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention was devised to effectively solve this problem in view of the present problems, and connects a plurality of heat pipes having excellent thermal conductivity between a pair of heat collecting tanks to form an auxiliary heat exchanger, and the heat exchanger is formed between an upper intake port and a blower. At the same time, the exhaust pipes connected between the heat exchanger and the exhaust port are connected to a pair of collection tanks, respectively, so that the waste heat discharged into the air is re-discharged from the upper side of the blower through a plurality of heat pipes to preheat the suction air. By providing the waste heat recovery device of the simple principle, the main purpose is to obtain both the effect of maximizing the thermal efficiency and the effect of minimizing the fuel consumption rate. The composition and the resulting effect thereof will be described in detail based on the accompanying drawings. .
