Description

탄화열 순환 방식 탄화로 시스템{The kiln for Heating Circulation}The Kiln for Heating < RTI ID = 0.0 > Circulation <

본 발명은 목탄 제조를 위한 탄화로 구조에 대한 것으로, 기존의 탄화로의 경우 탄화로의 구성이 개별적, 독립적인 구조로 설계되어 있어 탄화로 내에서 발생하는 탄화열이 낭비되는 구조로 되어 있으나, 본 발명의 탄화열 순환 방식 탄화로 시스템은 1차 탄화로(A)에서 탄화 과정에서 발생된 탄화열을 이용하여, 2차 탄화로(B) 내부에 적재된 목재의 수분을 17% 이하로 조절하여, 탄화 과정에서 필수적인 발생하는 목재 건조 건조 시간을 단축함으로써, 일반적으로 전체 탄화 공정에 소요되는 7일 정도의 시간을 4일 이내로 단축하여 목탄 제조에 소요되는 시간을 획기적으로 절감할 수 있는 시스템에 대한 것이다.The present invention relates to a charcoal furnace for producing charcoal. In the case of conventional charcoal furnaces, the charcoal furnace structure is designed individually and independently so that the heat of carbonization generated in the charcoal furnace is wasted. However, The carbonitriding system of the present invention can control the moisture content of the wood loaded in the secondary carbonization furnace (B) to 17% or less by using the heat of carbonization generated in the carbonization process in the primary carbonization furnace (A) By shortening the dry drying time of wood, which is indispensable to the carbonization process, it is possible to reduce the time required for charcoal production to a short time by shortening the time required for the entire carbonization process to within 4 days It is about.

본 발명은 1차 탄화로(A)의 폐열을 이용한 2차 탄화로(B)의 목재 건조 방법에 대한 것으로, 더욱 상세하게는 탄화로 내에서 나무를 태워 목탄을 제조 과정에서 발생하는 폐열, 즉 나무의 연소열을 이용하여 2차 탄화로(B) 내의 적층된 나무의 수분을 조절하는 탄화열 순환형 탄화로 시스템에 관한 것이다.The present invention relates to a method for drying wood of a secondary carbonization furnace (B) using waste heat of a primary carbonization furnace (A), more particularly, to a method of drying wood by burning wood in a carbonization furnace, The present invention relates to a carbonization heat-recycling type carbonization system for regulating moisture of a laminated wood in a secondary carbonization furnace (B) by using heat of combustion of wood.

일반적인 숯의 제조 과정을 보면, 먼저 가마의 입구를 통하여 내부에 나무를 적층하고, 입구를 밀폐한 다음, 아궁이에 불을 지펴 상부의 화구를 통하여 탄화로 내부로 열을 공급하여 나무가 상부로부터 하향 연소되면서 숯을 제조하는 방식으로 탄화로가 구성되어 있다. 이때 나무의 연소시 발생하는 연소열은 배출구 및 연통을 통하여 외부로 배출된다.In general, the process of manufacturing the charcoal is as follows: First, the wood is laminated through the entrance of the kiln, and the entrance is sealed. Then, the fire is lit in the oven and the heat is supplied to the inside of the carbonization furnace through the upper firebox, Carbonization furnaces are constructed by burning and producing charcoal. At this time, the heat of combustion generated when the wood is burned is discharged to the outside through the discharge port and the communication pipe.

이와 같을 목탄을 제조하는데 대락 5-6일 정도 걸리고, 제조된 목탄을 꺼낸 후 탄화로를 식히는데 걸리는 시간이 2-3일 정도이다. 전체 목탄 제조 공정에는 7-9일 정도 걸린다.It takes about 5-6 days to produce such charcoal, and it takes about 2-3 days to cool the charcoal after removing the charcoal. The entire charcoal manufacturing process takes about 7-9 days.

일반적으로 탄화로에서 탄화 과정에서 발생되는 폐열은 30,000kcal로서 매우 높다. 이러한 폐열이 아무런 활용이 없이 배출구를 통해 낭비되고 있는 문제점이 발생하고 있다.Generally, the waste heat generated in the carbonization process in the carbonization furnace is very high as 30,000 kcal. There is a problem that such waste heat is wasted through the discharge port without any utilization.

또한, 목탄 제조시 효율적인 목탄의 제조를 위해 목재의 수분량을 17% 이하로 조절하기 위해서 목재 건조실을 따로 운영되고 있다. 이때 소요되는 기간인 보통 2-3일 정도 소요된다.In addition, the wood drying chamber is operated independently to adjust the water content of the wood to 17% or less in order to produce charcoal efficiently in the production of charcoal. This takes about 2-3 days.

본 발명은 상기와 같은 종래의 문제점을 해소하기 위한 것으로, 그 목적은 탄화 과정에서 발생되는 폐열을 이용하여 2차 탄화로(B) 내의 목재의 수분 조절을 위한 건조 과정의 열원으로 이용함으로써, 1차 탄화로(A)에서 발생하는 탄화열의 낭비를 막음과 동시에 2차 탄화로(B) 자체를 건조실로 이용함으로써 건조실 구축 비용의 절감과 건조 후 탄화 과정에서 발생하는 목재의 건조실에서 탄화로의 이동 시간의 절감을 통해, 전체 탄화 과정의 비용과 시간을 줄일 수 있는 시스템을 제공하는데 있다.The object of the present invention is to solve the above-mentioned problems of the prior art by using waste heat generated in the carbonization process as a heat source for drying the wood in the secondary carbonization furnace B, It is possible to prevent the waste of the heat of carbonization occurring in the secondary carbonization furnace (A) and to reduce the cost of constructing the drying chamber by using the secondary carbonization furnace (B) itself as a drying chamber and to transfer the carbonization furnace from the drying chamber of the wood, Thereby reducing the time and cost of the entire carbonization process.

상기의 목적을 달성하기 위해 본 발명에서는 복수개의 탄화로와, 상기 복수개의 탄화로에서 발생하는 가스 및 탄화열의 배출을 위한 2개의 배출구(31,32,33,34), 그리고 각 배출구(31,32,33,34)에서는 발생하는 탄화열을 이동하기 위한 열전송관(21,22,23), 그리고 발생하는 탄화 가스를 외부로 배출하기 위한 연소구(11,12,13,14)와 탄화로에서 발생하는 가스와 탄화열을 연소구(11,12,13,14) 또는 열전송관(21,22,23)으로 방향 전환할 수 있는 밸브(41,42,43,44)와 탄화로에서 발생하는 가스와 탄화열의 상태를 파악하기 위한 온습도센서(61,62,63,64)와 온습도센서(61,62,63,64)의 정보를 취득하여 밸브(41,42,43,44)의 조절을 위한 제어반(51,52)으로 구성된다.In order to achieve the above object, according to the present invention, there are provided a plurality of carbonization furnaces, two outlets (31, 32, 33, 34) for exhausting gas and carbonization heat generated from the plurality of carbonization furnaces, 32, 33, 34), heat transfer tubes (21, 22, 23) for moving the generated heat of combustion, combustion holes (11, 12, 13, 14) for discharging generated carbonaceous gas to the outside, (41, 42, 43, 44) capable of redirecting gas and carbonized heat generated in the combustion chamber (11, 12, 13, 14) or heat transfer tubes Humidity and humidity sensors 61, 62, 63 and 64 for acquiring information on the state of the gas and the carbonized heat of the valves 41, And control panels 51,

이상에서 설명한 바와 같이 본 발명에서는 목탄의 제조 과정에서 필수 요소인 목재의 건조를 위한 건조실이 따로 필요하지 않으며, 건조실에서의 목재 건조 과정에 따른 열원을 목탄 제조 과정에서 낭비되고 있는 탄화열을 이용함으로써 에너지의 재활용이 가능하고, 건조실에서 탄화로로의 목재 이동 비용과 시간을 줄임으로써 목탄 제조를 단가를 낮출 수 있는 장점이 있다.As described above, in the present invention, a drying chamber for drying wood, which is an essential element in the process of manufacturing charcoal, is not required, and the heat source for drying the wood in the drying chamber is used by using the heat of carbonization, Energy can be recycled, and the cost of wood moving from the drying chamber to the carbonization furnace can be reduced, thereby reducing the manufacturing cost of the charcoal.
