현재 목재는 대부분 직접 가열 방식인 열풍과 수증기를 이용하여 건조시키고 있는 바, 이와 같이 건조된 목재는 습도 변화에 의한 내구력이 약해 뒤틀림, 변형 등이 발생하고 균류, 박테리아 침투에 대한 저항성도 매우 떨어진다. 그래서 목재의 부패 방지와 보존 처리를 위해 화학 방부 처리를 하고 있다. 한편, 주택과 조경시설물의 마감재로 그 수요가 급격히 증대되고 있는 방부목이 사용되어지고 있지만 반면에 습기에 약하고, 목재 변형이 심하고, 유해물질 방출 등 많은 문제점이 대두되었고 그에 따른 여러 가지 개선책이 제시되고 있다. 그러나 근본적인 문제점 즉, 습기와 주변 환경온도에 의한 목재의 변형문제와 화학 방부 처리제를 사용함으로써 발생하는 환경문제 특히 사람과 동물의 신체에 직접 접촉하는 곳에는 사용하지 말아야 하는 등 여전히 해결되지 않고 남아 있는 문제가 있다. Currently, most of the wood is dried using hot air and water vapor, which is a direct heating method. Thus, the dried wood is weak in durability due to humidity changes, causing warpage and deformation, and also has low resistance to fungus and bacteria. Therefore, chemical preservative treatment is performed to prevent rot and preservation of wood. On the other hand, as a finishing material for homes and landscaping facilities, there is a lot of problems, such as wood, which is rapidly increasing in demand, but it is weak in moisture, severely deformed wood, and release of harmful substances. have. However, the fundamental problems, such as deformation of wood due to moisture and ambient temperature and environmental problems caused by the use of chemical preservatives, should not be used in direct contact with humans and animals. there is a problem.
본 발명은 습기와 주변 환경온도에 의한 목재의 변형문제와 화학 방부 처리제를 사용함으로써 발생하는 환경문제와 화학약품을 사용하지 아니하고도 목재의 방부처리를 할 수 있는 과제를 해결하고자 하는 것이다. The present invention aims to solve the problem of deformation of wood due to moisture and ambient environmental temperature, environmental problems caused by using chemical preservatives and the preservative treatment of wood without using chemicals.
본 발명은 상기와 같은 과제를 해결하기 위하여 우선 과열증기를 발생하는 목재 건조 탄화장치를 제조한 후 상기 목재 건조 탄화장치에서 생성된 과열증기를 이용하여 천연 소재인 목재를 화학첨가물 없이 고열처리시킨 후 이 목재로 건축용 내(외)장재, 가구재, 공원, 놀이시설의 시설재와 바닥재(Deck)를 생산함으로써 기존 방부목의 환경문제와 인체유해성에 대한 문제점을 완전히 해결할 수 있게 되었다.In order to solve the above problems, the present invention first manufactures a wood drying carbonization apparatus that generates superheated steam, and then uses a superheated steam generated in the wood drying carbonization apparatus to heat the wood as a natural material without chemical additives. The production of interior and exterior materials for building, furniture, parks, amusement facilities, and flooring made of this wood completely solves the problems of environmental and human hazards of existing preserving wood.
과열증기를 이용한 목재 건조 탄화장치를 이용하여 저가의 목재를 내구성이 우수하고, 치수 안정성, 목재의 경도, 내후성이 향상된 고품질의 친환경 열처리목재를 생산함과 동시에 화학방부 처리로 인한 환경오염을 막을 수 있으며, 저렴한 비용으로 무 화학물 첨가 방부 목재를 생산함으로서 경제성을 높일 수 있다. 이와 같이 생산된 목재는 일반 목재에 비하여 수분함량이 낮으므로 열이나 습기에 의한 변형을 방지할 수 있음은 물론 햇빛이나 세균에도 강하다. 또 나무의 천연색상을 그대로 이용하므로 전체의 칼라를 일치시킬 수 있고 또 목재 내 수분함량이 일정하여, 제품의 온정성과 내구성을 보장할 수 있다. By using wood drying carbonization apparatus using superheated steam, we can produce high quality eco-friendly heat treated wood with excellent durability, improved dimensional stability, hardness of wood, and weather resistance, while preventing environmental pollution due to chemical preservation treatment. In addition, it can increase the economic efficiency by producing a non-chemical added preservative wood at a low cost. The wood produced in this way has a lower moisture content than ordinary wood, preventing deformation due to heat or moisture, as well as being resistant to sunlight and bacteria.

우선 과열증기를 이용한 건조 탄화 장치를 제조한다. First, a dry carbonization apparatus using superheated steam is manufactured.
상기 장치는 고열저장탱크(100), 열풍기(110), 과열증기실(200), 챔버(300), 제습장치(400), 팬(500)및 컨트롤 박스(미도시)로 구성된다. The apparatus consists of a high temperature storage tank 100, a hot air fan 110, a superheated steam chamber 200, a chamber 300, a dehumidifier 400, a fan 500 and a control box (not shown).
고열저장탱크(100)에는 열풍기(110)에서 발생한 열과 반응하여 포화증기를 발생시키는 반응물질이 저장되어 있다. 이와 같은 반응물질로는 물, 이산화탄소, 질소 등 여러 가지가 있다. 본 발명에서는 비용이 가장 저렴한 물을 사용하였지만 물, 이산화탄소, 질소 등을 각각 또는 혼합하여 사용할 수 있다. The high heat storage tank 100 stores a reactant that generates saturated steam by reacting with heat generated from the hot air fan 110. Such reactants include water, carbon dioxide, nitrogen, and the like. In the present invention, the cheapest water is used, but water, carbon dioxide, nitrogen, and the like may be used, respectively, or in combination.
열풍기는 가스, 경유, 석탄이나 목재슬러지 등을 연료로 이용할 수 있는 버너로서 시중에서 판매되고 있는 것을 구입하여 사용하였다.The hot air blower is a burner that can use gas, diesel, coal, wood sludge, etc. as a fuel.
한편, 상기 고열저장탱크(100)에는 포화증기를 유출하는 포화증기유출구(120)가 형성되어 있고, 상기 포화증기유출구(120)에는 상기 포화증기를 과열증기실(200)로 공급하는 포화증기공급관(130)이 연결되어 있다.On the other hand, the high temperature storage tank 100 is formed with a saturated steam outlet 120 for outflowing saturated steam, and the saturated steam outlet 120 is a saturated steam supply pipe for supplying the saturated steam to the superheated steam chamber 200. 130 is connected.
과열증기실(200)은 밀폐되어 있으며 그 내부를 열풍통과관(230)이 지나고 있고, 그 외부는 히터(210)가 밀착하여 감싸고 있다. The superheated steam chamber 200 is sealed and a hot air passing tube 230 passes through the inside of the superheated steam chamber 200, and the outside of the superheated steam chamber 200 wraps close to the heater 210.
또 과열증기실(200)에는 후술하는 바와 같이 챔버(300)를 순환하면서 사용되어 수분과 냄새로 오염된 과열증기(이하, ‘순환증기’라 함)가 제습장치(400)에서 수분이 제거된 후(이하, ‘제습증기’라 함) 냄새를 제거하기 위하여 과열증기실(200)로 유입되는 제습증기유입구(270)가 형성되어 있다. In addition, the superheated steam chamber 200 is used while circulating the chamber 300 as described below, and the superheated steam contaminated with moisture and odor (hereinafter, referred to as `` circulating steam '') is removed from the dehumidifying apparatus 400. Dehumidifying steam inlet 270 is introduced into the superheated steam chamber 200 to remove the after (hereinafter referred to as 'dehumidifying steam') odor.
히터(210)는 칸탈(열선)로 구성되어 과열증기실(200)에 밀착하여 감싸고 있다. 따라서 상기 고열저장탱크(100)로 부터 이송된 포화증기가 과열증기실(200)로 유입되어 과열증기실(200) 내부를 순환하면서 상기 열풍기(110)에서 발생한 열과 과열증기실(200)을 밀착하여 감싸고 있는 히터(210)의 열에 의해 더욱 가열되어 포화증기로부터 고온의 과열증기로 바뀐 후 챔버(300)로 공급되어 목재를 건조, 탄화시키게 된다. 후술하는 바와 같이 챔버(300)를 순환하면서 목재를 건조 탄화시키는 과정에서 적재된 목재로부터 나오는 수분, 냄새(Synthesis gas) 등으로 오염된 순환증기가 유입되어 과열증기실(200)을 순환하면서 오염물질이 연소되어 다시 깨끗한 과열증기로 재생하게 돼 있다. The heater 210 is composed of a cantal (heat wire) and wraps close to the superheated steam chamber 200. Therefore, the saturated steam transferred from the high temperature storage tank 100 flows into the superheated steam chamber 200 and circulates inside the superheated steam chamber 200, thereby closely contacting the heat generated from the hot air fan 110 with the superheated steam chamber 200. It is further heated by the heat of the heater 210 is wrapped to change from saturated steam to high temperature superheated steam and then supplied to the chamber 300 to dry and carbonize wood. As described later, in the process of drying and carbonizing wood while circulating the chamber 300, circulating steam contaminated with water, odor (Synthesis gas), etc., from the loaded wood is introduced to circulate the superheated steam chamber 200 while polluting the contaminants. Is burned and regenerated with clean superheated steam.
챔버(300)는 통상 도자기 굽는 가마 형태를 이용하였지만 그 구조는 상이(相異)하다. 챔버(300) 하부에는 챔버(300) 내부에 적재된 목재를 탄화시킬 과열증기가 유입되는 과열증기유입구(310)가 형성되어 있고 챔버(300) 상부에는 챔버(300) 내부를 순환하면서 목재를 건조 탄화시킨 순환증기가 배출되는 순환증기유출구(320)가 형성되어 있다. The chamber 300 generally used a ceramic pot, but its structure is different. The superheated steam inlet 310 through which superheated steam to carbonize the wood loaded in the chamber 300 is formed at the lower portion of the chamber 300, and the wood is dried while circulating inside the chamber 300. A circulating steam outlet 320 for discharging carbonized circulating steam is formed.
한편, 챔버(300)에는 챔버(300) 내부의 온도를 감지하는 센서(360) 및 챔버(300)내부의 온도가 300℃를 초과하면 순환증기를 배출시키는 안전밸브(350)가 부착되어 있다. 또 챔버(300)내부의 온도가 과열되면 열풍기(110)의 가동을 정지시키는 자동제어 장치가 컨트롤 박스(미 도시)내에 설치되어 있어 챔버(300)내부의 온도가 300℃를 초과하면 열풍기(110)의 가동을 정지시키도록 되어 있다.On the other hand, the chamber 300 is attached to the sensor 360 for detecting the temperature inside the chamber 300 and the safety valve 350 for discharging the circulating steam when the temperature inside the chamber 300 exceeds 300 ℃. In addition, an automatic control device for stopping the operation of the hot air fan 110 when the temperature inside the chamber 300 is overheated is installed in a control box (not shown). When the temperature inside the chamber 300 exceeds 300 ° C., the hot air fan 110 ) Is stopped.
한편, 챔버(300) 하부에 이송레일(343)을 설치하면 건조탄화 할 목재를 적재한 이송차(340)를 운반하기가 용이하다.On the other hand, when the transport rail 343 is installed in the lower chamber 300, it is easy to transport the transport truck 340 loaded with the wood to dry carbonization.
제습장치(400)는 챔버(300)를 순환하면서 목재를 건조탄화시키면서 오염된 순환증기가 유입되는 순환증기유입구(410)와 상기 오염된 순환증기 중 수분이 제거되고 냄새만 남은 제습증기를 정화하기 위하여 유출하는 제습증기유출구(420)가 형성되어 있다.The dehumidifier 400 circulates the chamber 300 while drying carbonized wood to purify the dehumidifying steam in which the circulating steam inlet 410 into which the contaminated circulating steam is introduced and the moisture of the contaminated circulating steam are removed and only the smell remains. Dehumidifying steam outlet 420 is discharged for the purpose is formed.
팬(500)은 과열증기실(200)에서 생성된 과열증기를 챔버(300)로 빠르게 이송시키며, 팬(510)은 제습장치(400)에서 수분이 제거된 제습증기를 과열증기실(200)로 빠르게 보낸다. The fan 500 quickly transfers the superheated steam generated in the superheated steam chamber 200 to the chamber 300, and the fan 510 superheated steam chamber 200 in which the dehumidified steam from which the moisture is removed from the dehumidifier 400 is removed. Send to quickly.
컨트롤 박스는 열풍기(110), 센서(360), 안전밸브(350), 팬(500,510)을 미리 설정해 놓은 온도, 시간에 따라 자동으로 작동되도록 구성되어 있다.The control box is configured to automatically operate according to the temperature and time set in advance for the hot air fan 110, the sensor 360, the safety valve 350, and the fans 500 and 510.
이하에서는 과열증기를 이용한 목재 건조 탄화장치의 작동에 대하여 설명한다.Hereinafter will be described the operation of the wood drying carbonization apparatus using superheated steam.
열풍기(110)를 작동하여 발생한 열은 1차로 열풍통과관(230)을 통해 고열저장탱크(100)로 유입되어 고열저장탱크(100)에 저장되어 있는 반응물질을 가열하게 되며, 이와 같이 가열된 반응물질은 포화증기로 된다.The heat generated by operating the hot air blower 110 is first introduced into the high heat storage tank 100 through the hot air passage tube 230 to heat the reactants stored in the high heat storage tank 100, and thus heated. The reactant is saturated steam.
상기 포화증기는 포화증기유출구(120)에 연결되어 있는 포화증기공급관(130)을 통해 과열증기실(200)로 공급된다. The saturated steam is supplied to the superheated steam chamber 200 through the saturated steam supply pipe 130 is connected to the saturated steam outlet 120.
과열증기실(200)에는 고열저장탱크(100)로부터 공급되는 포화증기가 유입되는 포화증기유입구(220)가 형성되어 있다. 따라서 상기 포화증기유입구(220)로 유입된 포화증기는 히터(210)가 밀착되어 있는 과열증기실(200)을 순환하면서 상기 히터(210)에서 발생하는 열과 과열증기실(200) 내부를 통과하는 열풍통과관(230)에서 발생하는 열에 의해 더욱 뜨겁게 가열되어 포화증기내의 수분입자가 미세하게 분할되어 고열의 과열증기로 변하게 되며 그 결과 과열증기실(200)로 유입된 포화증기는 600~700℃의 과열증기로 변하게 된다. 그러나 목재를 탄화시키는 온도는 180~300℃면 충분하므로 과열증기실(200)에서 생성하는 과열증기의 온도는 미리 180~300℃로 설정한다.The superheated steam chamber 200 is formed with a saturated steam inlet 220 into which the saturated steam supplied from the high heat storage tank 100 flows. Therefore, the saturated steam introduced into the saturated steam inlet 220 circulates the superheated steam chamber 200 in which the heater 210 is in close contact with the heat generated from the heater 210 and passes through the superheated steam chamber 200. Heated more hot by the heat generated in the hot air passage 230, the water particles in the saturated steam is finely divided into a superheated steam of high heat, as a result of the saturated steam introduced into the superheated steam chamber 200 600 ~ 700 ℃ It turns into superheated steam. However, the temperature of carbonizing wood is 180 ~ 300 ℃ is sufficient, so the temperature of the superheated steam generated in the superheated steam chamber 200 is set to 180 ~ 300 ℃ in advance.
이와 같이 생성된 과열증기는 과열증기유출구(250)에 연결된 과열증기공급관(260)을 통해 챔버(300)로 공급된다.The superheated steam thus generated is supplied to the chamber 300 through the superheated steam supply pipe 260 connected to the superheated steam outlet 250.
챔버(300)는 통상 도자기 굽는 가마 형태를 이용하지만 그 구조는 상이하다. 챔버(300)하부에는 과열증기실(200)로부터 공급된 과열증기가 유입되는 과열증기유입구(310)가 형성되어 있고 챔버(300) 상부에는 챔버(300) 내부를 순환하면서 목재를 건조 탄화시킨 순환증기를 배출하는 순환증기유출구(320)가 형성되어 있다. 상기 과열증기유입구(310)는 챔버(300)하부에 위치하고 있어야 챔버(300)로 유입된 과열증기가 챔버(300) 밑에서부터 적재된 목재 사이를 순환하면서 위로 올라가 챔버(300)에 적재된 목재를 차례로 건조 탄화시키게 된다. The chamber 300 generally uses a ceramic potter's oven, but the structure is different. The superheated steam inlet 310 through which the superheated steam supplied from the superheated steam chamber 200 is introduced is formed below the chamber 300, and the upper part of the chamber 300 circulates through the chamber 300 while drying and carbonizing wood. A circulating steam outlet 320 for discharging steam is formed. The superheated steam inlet 310 has to be located under the chamber 300 so that the superheated steam introduced into the chamber 300 circulates from the bottom of the chamber 300 to the top of the stacked wood, thereby moving up the wood loaded in the chamber 300. Dry carbonization in turn.
한편, 챔버(300)에는 안전밸브(350)와 센서(360)가 설치되어 있어 챔버(300) 내부온도가 설정값(300℃)에 도달하게 되면 상기 센서(360)가 이를 감지하여 컨트롤박스로 통지하게 되며, 이 통지를 받은 컨트롤박스는 열풍기(110)의 작동을 멈추게 한다. 또 챔버(300) 내부온도가 설정 값(300℃)을 넘게 되면 안전밸브(350)가 자동으로 열려 과열증기를 챔버(300) 밖으로 배출시켜 챔버(300)의 내부온도를 항상 설정값(300℃)온도로 유지시킨다.On the other hand, the chamber 300 is provided with a safety valve 350 and the sensor 360 so that when the internal temperature of the chamber 300 reaches the set value (300 ℃), the sensor 360 detects this to the control box Notified, the control box received this notification to stop the operation of the hot air fan (110). In addition, when the internal temperature of the chamber 300 exceeds the set value (300 ° C.), the safety valve 350 automatically opens to discharge the superheated steam out of the chamber 300 to always set the internal temperature of the chamber 300 (300 ° C.). Keep at the temperature.
한편, 챔버(300)하부에 이송레일(343)을 설치하면 건조 탄화할 목재를 적재한 이송차(340)를 운반하기가 용이하다.On the other hand, if the transport rail 343 is installed below the chamber 300, it is easy to transport the transport truck 340 loaded with the wood to dry carbonization.
챔버(300)로 유입된 과열증기는 챔버(300)안에 적재된 목재 사이를 밑에서부터 위로 순환하며 올라가면서 목재를 건조 탄화시키게 된다. 이와 같이 챔버(300)내부를 순환하면서 목재를 건조 탄화시킨 순환증기의 온도는 챔버(300)에 유입될 때의 온도보다 30~50℃낮아지고, 또 목재가 건조 탄화되면서 배출하는 수분과 냄새가 섞여져 순환증기는 오염되게 된다. The superheated steam introduced into the chamber 300 circulates from bottom to top between the wood loaded in the chamber 300 to dry carbonize the wood. As described above, the temperature of the circulating steam which dry carbonizes the wood while circulating inside the chamber 300 is 30 to 50 ° C. lower than the temperature when it is introduced into the chamber 300, and the moisture and odor emitted by the wood as the carbon is dry carbonized. Mixed, the circulating steam becomes contaminated.
이와 같이 오염된 순환증기는 순환증기유출구(320)에 연결된 순환증기유출관(330)을 통해 제습장치(400)로 이송된다. The contaminated circulating steam is transferred to the dehumidifier 400 through the circulating steam outlet pipe 330 connected to the circulating steam outlet 320.
제습장치(400)로 유입된 순환증기는 제습되는 과정에 온도가 다시 100~120℃로 떨어지는 한편, 순환증기에 섞여 있던 수분은 응축수로 변하면서 제습장치(400) 내부로 흐르게 되어 과습(過濕)되었던 순환증기는 습도가 낮은 제습증기로 변하게 된다. 그러나 목재로부터 나온 각종 냄새는 그대로 남아 있다. 상기와 같이 습기는 없지만 냄새로 오염된 제습증기는 제습증기유출구(420)에 연결된 제습증기유출관(430)을 통해 다시 과열증기실(200)로 이송된다. While the circulating steam introduced into the dehumidifier 400 falls back to 100-120 ° C. during the dehumidification process, the moisture mixed with the circulating steam is converted into condensed water and flows into the dehumidifying apparatus 400 so as to be humidified. The circulated steam is turned into a low humidity dehumidified steam. However, the various smells from the wood remain intact. As described above, the dehumidified steam contaminated by the smell, but not odor, is transferred back to the superheated steam chamber 200 through the dehumidified steam outlet pipe 430 connected to the dehumidified steam outlet 420.
제습증기유입구(270)를 통해 과열증기실(200)로 이송된 오염된 제습증기는 과열증기실(200)내부를 순환하면서 열풍기(110)와 히터(210)로부터 발생되는 180~300℃의 고열에 의하여 과열증기에 섞여 있던 냄새는 연소되어 깨끗한 과열증기로 재생하게 된다. 이와 같이 냄새가 제거되어 깨끗하게 재생된 과열증기는 과열증기유출구(250)를 통해 챔버(300)에 공급되어 재사용되게 된다.The contaminated dehumidified steam transferred to the superheated steam chamber 200 through the dehumidified steam inlet 270 circulates inside the superheated steam chamber 200 while being heated at a temperature of 180 to 300 ° C. generated from the hot air fan 110 and the heater 210. The smell mixed with superheated steam is burned and regenerated by clean superheated steam. In this way, the superheated steam that is cleanly regenerated by odor is supplied to the chamber 300 through the superheated steam outlet 250 and reused.
상기와 같이 오염을 제거하기 위하여 과열증기실(200)로 유입되는 제습증기의 온도는 아직도 100~120℃의 고온 증발증기이므로 보다 조금만 열을 가하여도 180~300℃의 필요한 온도까지 올릴 수 있다. 따라서 열풍기(110)와 히터(210)를 풀가동하지 않아도 고온의 증발증기를 재활용함으로써 에너지를 20~30% 절감할 수 있다. In order to remove the contamination as described above, the temperature of the dehumidifying steam introduced into the superheated steam chamber 200 is still a high temperature evaporative steam of 100-120 ° C., so that even a little more heat can be raised to the required temperature of 180-300 ° C. Therefore, energy consumption can be reduced by 20 to 30% by recycling high temperature evaporative steam without full operation of the hot air fan 110 and the heater 210.

이어 본 발명의 과열증기를 이용한 목재 건조 탄화장치를 이용하여 목재를 열처리하는 방법에 대하여 설명한다.Next, a method of heat treating wood using a wood drying carbonization apparatus using superheated steam of the present invention will be described.
우선 건조, 탄화시킬 목재를 준비하고 상기 준비된 목재를 그대로 또는 건축용 내(외)장재, 가구재, 공원, 놀이시설의 시설재와 바닥재(Deck)로 1차 가공한 상태로 준비한다. First, the wood to be dried and carbonized is prepared, and the prepared wood is prepared as it is or in the state of primary processing of interior and exterior building materials, furniture materials, parks, amusement facilities and floor materials (Deck).
통상 건축 내(외)장재. 가구재, 시설재, 바닥재(Deck)로 사용 가능한 수종은 특별히 정해져 있지는 않고, 목재생산 지역과 사용조건에 따라 목재 수종을 선택 할 수 있다. Normally interior and exterior building materials. The species that can be used for furniture, facilities, and decking are not specifically defined. Wood species can be selected according to the wood production area and the conditions of use.
이어 이송차(340) 위에 적재편(342)을 올려놓고 적재편(342) 위에 목재를 차곡차곡 쌓아 놓는다. 이송차(340)는 일반 목재 건조시 사용하는 이송차(340)를 사용한다. 상기 이송차(340)에는 바퀴가 붙어 있어 이송레일(343)을 통해 힘들이지 않고 이송할 수 있다.Subsequently, the stacking piece 342 is placed on the transporting vehicle 340, and wood is stacked on top of the stacking piece 342. The transport truck 340 uses a transport truck 340 used for general wood drying. The transfer vehicle 340 is attached to the wheel can be transferred without effort through the transfer rail (343).
이 때 목재를 쌓아 놓는 목재 각층 사이에는 통풍이 잘 되도록 적재편(342)두께를 3~20mm로 하여 틈을 만든다. 이와 같이 목재 각층 사이에 틈이 있어야 목재를 건조, 탄화시킬 때 뜨거운 열이 목재 사이를 골고루 순환할 수 있어 챔버(300)내 목재가 함수율 편차 없이 고르게 건조, 탄화될 수 있다. At this time, the gap between each layer of wood stacking timber stacking piece (342) to 3-20mm to make a good ventilation. As such, when there is a gap between each layer of wood, hot heat can be evenly circulated between the wood when the wood is dried and carbonized, so that the wood in the chamber 300 can be evenly dried and carbonized without variation in moisture content.
상기와 같이 목재가 적재되면 이송레일(343)을 통해 이송차(340)를 챔버(300)내부로 이송한 후 챔버(300) 내부로 외부 공기가 들어가지 못하도록 완전하게 밀폐한다. When the timber is loaded as described above, the transport vehicle 340 is transferred into the chamber 300 through the transport rail 343 and completely sealed to prevent external air from entering the chamber 300.
한편, 목재는 수종에 따라 차이가 있지만 180~300℃사이에서 건조, 탄화시킨다. 따라서 챔버(300) 내부온도를 상기 온도로 설정한다. On the other hand, wood is different depending on the species, but dried and carbonized between 180 ~ 300 ℃. Therefore, the temperature inside the chamber 300 is set to the temperature.
이어 컨트롤박스를 작동하여 과열증기실(200)에서 180~300℃의 과열증기를 생성한 후 과열증기공급관(260)을 통해 과열증기를 밀폐된 챔버(300) 내부로 공급한다. 이 때 과열증기공급관(260)에 설치된 팬(500)이 작동하여 과열증기를 챔버(300)로 신속하게 공급하는 한편, 챔버(300) 내부의 목재 틈 사이를 골고루 순환하게 한다. 이와 같이 뜨거운 과열증기가 챔버(300)내부로 공급되더라도 챔버(300) 내부가 넓으므로 챔버(300)내부에 최초로 공급된 과열증기의 온도는 크게 떨어지게 되지만 계속 공급되는 과열증기로 인하여 챔버(300) 내부 온도는 빠르게 올라가게 된다. 그리고 챔버(300)내부 온도가 180~300℃에 도달하면 목재 내부에서 부터 셀룰로오즈(cellulose)의 결정체 크기 증가와 리그닌(lignin)의 물리구조가 개변되어 물을 잘 흡수하지 않고, 수분함량이 적어져 습도 변화에 대한 내구력과 재질(규격) 온정성이 크게 개선되고, 균류와 박테리아의 자양분이 되는 헤미셀룰로오즈(hemicellulose)가 분해 되어 물질적 부패가 발생하지 않아 균이나 흰개미로부터 보호되어 방부 내구성과 생물학적 내구성이 크게 개선되고, 날씨 변화에 대한 저항력도 크게 향상된다. 그러므로 과열증기로 인하여 세포가 분해되는 생태변화가 일어나면서 목재 내부의 수분을 거의 모두 배출하게 되어 목재 내부의 함수율은 제로에 가깝게 되면서 목재는 서서히 건조 구간을 지나 탄화되기 시작한다. Subsequently, the control box is operated to generate superheated steam at 180 to 300 ° C. in the superheated steam chamber 200, and then the superheated steam is supplied into the closed chamber 300 through the superheated steam supply pipe 260. At this time, the fan 500 installed in the superheated steam supply pipe 260 is operated to quickly supply the superheated steam to the chamber 300, while circulating evenly between the wood gaps in the chamber 300. Thus, even if the hot superheated steam is supplied into the chamber 300, the inside of the chamber 300 is wide so that the temperature of the superheated steam first supplied into the chamber 300 is greatly reduced, but the chamber 300 is continuously supplied due to the superheated steam. The internal temperature rises quickly. When the temperature inside the chamber 300 reaches 180 ~ 300 ° C., the crystal size of cellulose and the lignin's physical structure are changed from the inside of the wood, so that the water content is not absorbed well and the moisture content is reduced. Durability and material (standard) resistance to changes in humidity are greatly improved, and hemicellulose, which is a nutrient for fungi and bacteria, is decomposed, so that no material decay occurs and it is protected from bacteria and termites, so that antiseptic durability and biological durability are improved. It is greatly improved, and the resistance to weather changes is greatly improved. Therefore, as the ecological change in which the cells are decomposed due to the superheated steam causes almost all moisture in the wood to be discharged, the water content in the wood is close to zero, and the wood gradually starts to carbonize through the drying section.
이와 같이 건조탄화된 목재는 낮은 함수율과 목재 내부의 생태변화로 인하여 안정성(stability)을 갖게 됨은 물론 목재의 수분 침투성(permeability)이 현저하게 낮아진다. Such dry carbonized wood has stability due to low water content and ecological change inside the wood, and also significantly lowers the water permeability of the wood.
또 열 전도성(thermer property)이 일반 목재보다 현저하게 낮으므로 단열재로서의 기능도 갖추게 됨은 물론 햇빛과 풍상에 따른 색상의 변화도 거의 없게 되며, 벌레나 세균에 의한 목재의 부패도 효율적으로 예방할 수 있게 되어 기존의 목재방부 처리방식인 화학방부처리를 하지 않아도 탁월한 방부성능을 갖는 친환경 방부목이 된다.In addition, since the thermal property is significantly lower than that of ordinary wood, it has a function as an insulating material, and there is almost no change in color due to sunlight and weather. It is an eco-friendly preservative wood with excellent antiseptic performance without chemical preservative treatment, which is a conventional wood antiseptic treatment.
목재가 건조탄화되는 과정에서 목재의 색상을 다양하게 하기 위하여 온도를 서서히 올린다. 이와 같이 온도를 서서히 올리면 목재는 처음에는 엷은 갈색으로 변하고 계속하여 올리면 짙은 갈색으로 변하였다가 엷은 검은색을 거쳐 수종에 따라 일정한 시간경과 후에는 검은색으로 변하게 된다.As the wood is dry carbonized, the temperature is gradually raised to vary the color of the wood. As you gradually increase the temperature, the wood first turns to light brown, and if you continue to raise it to dark brown, it goes through pale black and turns to black after a certain time depending on the species.
상기와 같이 원하는 색상에 도달하면 챔버(300)내부 온도를 천천히 낮춘다. 챔버(300)내부 온도를 빨리 낮추게 되면 나무의 갈라짐(crack) 현상 또는 뒤틀림이 발생할 수 있으므로 가능한 한 챔버(300)내부 온도를 천천히 낮추는 것이 바람직하다. When the desired color is reached as described above, the temperature inside the chamber 300 is slowly lowered. It is desirable to lower the internal temperature of the chamber 300 slowly as much as possible because a rapid cracking of the internal temperature of the chamber 300 may cause cracking or distortion of wood.
또 상기와 같이 온도와 조건에 따라 색상이 변하게 되지만 나무의 결은 그대로 있고 목재 전체가 골고루 같은 색으로 변하게 되므로 자연스러운 나무결을 가진 균일한 색상의 목재를 대량으로 생산할 수 있다.In addition, the color is changed according to the temperature and conditions as described above, but the grain of the wood is intact and the entire wood is changed to the same color, so that the wood of a uniform color with natural wood grain can be produced in large quantities.
이와 같이 열처리된 목재의 품질을 더욱 높이기 위해서는 목재표면을 샌드페이퍼 등으로 연마한 후 천연의 광택 오일(티크오일과 아마씨 오일을 배합한 것)이나 옻칠을 목재표면에 발라 광을 낸 후에 시공하면 목재의 품질이 더욱 보장된다. In order to further improve the quality of the heat-treated wood, the surface of the wood is ground with sandpaper, etc., and then polished with natural luster oil (mixed with teak oil and flaxseed oil) or lacquer on the surface of the wood, Quality is further guaranteed.
