본 발명은 폐목재나 잡목의 부스러기를 이용하여 고형염료를 제조함에 의해 폐목재나 잡목의 소비를 늘려 이들에 의해 환경이 오염되는 것을 방지할 수 있을 뿐만 아니라 불필요한 자원을 절감할 수 있다.According to the present invention, it is possible to prevent pollution of the environment by increasing the consumption of waste wood or debris by manufacturing a solid dye using waste wood or debris, as well as to reduce unnecessary resources.
본 발명에 따른 목재 부스러기로 만들어진 고형연료 제조방법은 톱밥이나 대패밥 또는 벌목 과정에서 생산되는 목재를 분쇄한 부스러기로 만들어지는 목재 부스러기로 만들어진 고형연료 제조방법으로, 목재 부스러기를 분쇄하는 분쇄단계; 분쇄된 목재 부스러기, 접착제를 혼합하는 원료혼합단계; 혼합된 원료를 가열 및 가압하여 성형하는 1차가압성형단계; 분쇄된 목재 부스러기, 접착제 및 촉화제을 혼합하는 점화원료혼합단계; 1차가압성형된 중간제품의 적어도 일면에 점화원료를 도포 후 가압하는 2차성형단계를 포함한다.The solid fuel manufacturing method made from wood chips according to the present invention is a solid fuel manufacturing method made from sawdust, planer rice, or wood chips made from pulverized wood produced in a logging process, the method comprising: pulverizing the wood chips; Raw material mixing step of mixing the pulverized wood chips and adhesive; a primary pressure molding step of molding by heating and pressing the mixed raw material; Ignition raw material mixing step of mixing the pulverized wood chips, adhesive and accelerator; and a secondary molding step of applying an ignition raw material to at least one surface of the primary pressure-molded intermediate product and then pressing.
상기 분쇄단계는 목재를 소정의 입도 이하로 분쇄하는 단계로, 톱밥의 경우 입도가 이미 작은 상태임에 따라 분쇄하지 않고 혼합되고, 톱밥의 입도가 지나치게 작음에 따라 톱밥보다 상대적으로 크게 목재를 분쇄한다. The pulverization step is a step of pulverizing the wood to a predetermined particle size or less. In the case of sawdust, since the particle size is already small, it is mixed without pulverization, and as the particle size of the sawdust is too small, the wood is pulverized relatively larger than sawdust. .
즉, 대패밥이나 목재를 분쇄하되 이들을 구형 입자 형태가 아니라 굵기가 가늘고 길게 분쇄하고, 원료혼합단계에서 분쇄된 분쇄목재에 톱밥을 혼합하여 톱밥이 분쇄 분쇄목재 사이에 혼합되게 한다. That is, the planer rice or wood is pulverized, but they are not in the form of spherical particles, but pulverized to a long and thin thickness, and the sawdust is mixed with the pulverized pulverized wood in the raw material mixing step so that the sawdust is mixed between the pulverized pulverized wood.
상기 분쇄단계에서 분쇄된 분쇄목재의 크기는 굵기가 0.1 ~ 2mm이고, 길이가 3 ~ 10mm정도인 것이 바람직하다. 이는 분쇄과정에서 보다 미세하게 분쇄하기 위해서는 분쇄에 많은 시간이 소요됨은 물론 분쇄장치의 정밀도가 높아야 함에 따라 장치의 구성에 어려움이 있고, 이러한 단점을 개선할 뿐만 아니라, 지나치게 잘게 분쇄할 경우 오히려 쉽게 타 화력의 지속성이 떨어질 수 있기 때문이다. The size of the pulverized wood pulverized in the pulverizing step is preferably 0.1 to 2 mm in thickness and 3 to 10 mm in length. In order to pulverize more finely in the pulverization process, it takes a lot of time for pulverization, and as the precision of the pulverizing device must be high, there is a difficulty in the configuration of the device. This is because the durability of the firepower may decrease.
상기 원료혼합단계는 목재 부스러기에 다른 첨가제를 혼합하는 단계로, 상기한 바와 같이 주 원료인 목재부스러기는 톱밥과 분쇄목재 모두가 사용되는 것이 바람직하다.The raw material mixing step is a step of mixing other additives to the wood shavings, and as described above, it is preferable that both sawdust and pulverized wood are used as the main raw material for wood shavings.
상기 원료혼합단계에서 혼합되는 첨가제는 상기한 바와 같이 목재 부스러기들 사이의 결합을 위한 접착제가 될 수 있다. The additive mixed in the raw material mixing step may be an adhesive for bonding between wood shavings as described above.
상기 접착제는 다양한 형태의 목재 접착제가 사용될 수 있으나, 화학 접착제의 경우 연소과정에서 유해성분이 발생할 수 있음에 따라 천연 접착제를 사용하는 것이 바람직하고, 그 예로 송진을 포함하는 접착성과 발화온도가 낮은 나무수액이 사용하는 것이다.As the adhesive, various types of wood adhesives can be used, but in the case of chemical adhesives, it is preferable to use natural adhesives because harmful components may be generated during combustion. For example, wood sap containing rosin and low ignition temperature this will use
또한 상기 첨가제에는 연소과정에서 유익한 향을 발생시키는 라벤더, 로즈마리 등의 오일을 첨가하는 것이 바람직하다.In addition, it is preferable to add oils such as lavender and rosemary, which generate a beneficial fragrance during the combustion process, to the additive.
상기 1차가압성형단계는 혼합된 원료를 가열 및 가압하여 소정의 형상을 만드는 성형단계이다. The primary pressure forming step is a forming step of heating and pressurizing the mixed raw material to form a predetermined shape.
이 1차가압성형단계에서 가해지는 온도는 접착제가 경화될 수 있는 정도의 온도로, 접착제의 성질에 따라 달라질 수 있다. The temperature applied in this primary pressure molding step is a temperature at which the adhesive can be cured, and may vary depending on the nature of the adhesive.
즉, 가열온도는 혼합된 접착제로부터 수분이 증발하여 나무 부스러기들이 서로 엉켜 접착될 수 있는 정도의 온도이다. That is, the heating temperature is a temperature at which moisture is evaporated from the mixed adhesive and the wood shavings can be entangled and adhered to each other.
상기 1차가압성형단계에서 가압되는 압력은 0.5ton/㎠∼1.5ton/㎠인 것이 바람직하다. 이는 본 발명의 제조방법에서 사용되는 목재부스러기가 톱밥과, 톱밥보다 상대적으로 입도가 큰 분쇄목재로 이루어지고, 압력이 이 범위보다 낮으면 목재부스러기들이 뭉쳐지지 않아 쉽게 부스러지거나 공극(空隙)이 지나치게 많아 오히려 화력이 역해질 수 있고, 압력이 이 범위보다 높으면 경도가 높고 목재부스러기들 사이에 공극이 없어 연소가 잘 이루어지지 않을 수 있기 때문이다. It is preferable that the pressure applied in the primary pressure forming step is 0.5 ton/cm 2 to 1.5 ton/cm 2 . This is that the wood chips used in the manufacturing method of the present invention are made of sawdust and pulverized wood having a relatively larger particle size than sawdust, and when the pressure is lower than this range, the wood chips are not agglomerated and easily crumbled or the voids are excessive. This is because, if the pressure is higher than this range, the hardness is high and there is no void between the wood shavings, so combustion may not be performed well.
상기 점화원료혼합단계는 본 발명의 고형연료가 쉽게 점화되게 하기 위한 점화원료를 혼합하는 단계로, 역시 목재 부스러기가 주원료가 되고, 보조재료로 접착제 및 촉화제가 더 혼합된다. The ignition raw material mixing step is a step of mixing the ignition raw material for easily igniting the solid fuel of the present invention.
접착제는 상기 원료혼합단계에서 혼합되는 접착제와 동일하다.The adhesive is the same as the adhesive mixed in the raw material mixing step.
촉화제는 발화온도가 낮은 다양한 오일이 사용될 수 있으나, 화학성분의 경우 착화시 연기 및 유해성분이 발생할 수 있으므로 식물성오일을 사용하는 것이 바람직하다.Various oils with a low ignition temperature may be used as the accelerator, but in the case of chemical components, it is preferable to use vegetable oil because smoke and harmful components may be generated during ignition.
식물성오일의 예로는 참기름, 콩기름, 아주까리기름, 동물기름, 생선기름 등이 사용될 수 있으나, 착화시 그을음이 발생하지 않는 것을 선택하여 사용한다. Examples of vegetable oils include sesame oil, soybean oil, castor oil, animal oil, fish oil, etc., but select one that does not generate soot during ignition.
상기 2차성형단계는 점화원료혼합단계에서 혼합된 점화연료를 중간제품의 표면 중 적어도 일면에 접착하여 성형하는 단계이다. The secondary molding step is a step of bonding the ignition fuel mixed in the ignition raw material mixing step to at least one surface of the intermediate product and molding it.
