Description

FIELD OF THE INVENTION [0001] The present invention relates to a method for producing a high-

More particularly, the present invention relates to a method for commercializing a highly efficient fuels such as pine tree rehabilitation bottles and oak wilt disease, which are socially problematic in wood biomass, .

At present, forests in Korea are encouraged to use thinning materials obtained through the government 's "forestry business" and encourage various use revitalization projects in order to activate the use of domestic materials including bouy bees. Most of the natural forests, which are relatively short-lived and hardwood-oriented, are not used as high value-added materials such as furniture or building materials, which are characteristics of domestic forest resources devastated after the Korean War. In recent years, attempts have been made to use MDF, PB, pulp chips, and fuel pellets by using domestic thinning materials.

Even with such thinning materials, even the use of pests and diseases is very limited due to concerns about transmission. It is necessary to identify the number of infected woods and infestation plan of wood infested with pine woodworm disease, which is the most serious problem in Korea, and plan for the control of the disease.

In the case of wood infected with pine wilt disease, the cause is the parasitism on the body of the pine tree whistle, which is caused by the re-infestation when the adult pine leaves are eaten by the infested pine tree. The first occurrence occurred in 1988, The number of victims in the year 2009 was 267 thousand, the number of deaths in 2009 was 133 thousand, the number of deaths in the year 11 was 477 thousand There are 506 thousand trees in 12 years, and 1,231 thousand trees in 13 years. As a result, the population and activity of the insecticide caused by high temperatures and drought during the summer period increased rapidly due to the inability to control the whole damaged dead wood before the alpine period. Also, the lack of interest of the local government, As a result of the artificial movement of pine trees, the incidence of new damage increased nationwide. If the total area to be controlled is added, the total cost will be 13,227ha.

 In the case of timber infected with oak woodchip disease, it is said that the root cause of the wood is caused by a long tree in the forest, causing a hole in the oak tree to infect and infect the pathogens of the lephelia and blocking the water passage of the stem. This is because it is known to occur frequently in the metropolitan area. This is because there are many shingles and mulrums that are susceptible to oak tree disease. Despite the steady efforts, the affected areas are being expanded to Gyeonggi and southern regions, . In the case of the dead tree damage status by national year, 181 thousand in 10 years, 331 thousand in 11, 268 thousand in 12, and 309 thousand in 13 years are carried out and the habitat environment of temperature such as temperature, If conditions are met, the damage can spread. A total of 432,942 control measures are needed for the spread prevention project, and the total cost of the project is 6,586 million won.

In response to this, the government has established a plan to minimize the damage caused by the investigation of damage history, the detailed control strategy suitable for the type of damage in each region, the intensive control of the damaged dead wood and the precautionary measures, However, there is a problem that it takes a great deal of human and economic burden and it is necessary to find a plan to solve this problem effectively from the point of view of the usefulness of the pest control tree .

However, the most important prerequisite for considering how to introduce it into commercialization is the need to develop an application suitable for value-added, and an effective drying method to eliminate the concerns of further infestation by drying methods for such use. Generally, the method of drying the moisture contained in the wood includes a natural drying method in which the raw timber is left to stand for a long period of about 3 to 5 years in a timber drying plant and a natural drying method in which timber or lumber is used for building or furniture There is an artificial drying method in which raw timber processed with lumber is first loaded in a drying chamber and then the inside of the drying chamber is dried at a high temperature of 56 to 120 ° C or higher over several days.

A conventional drying furnace used in such a conventional artificial drying method is shown in Fig. The drying furnace 100 shown in FIG. 1 is constructed such that raw timber processed primarily by shaving wood is loaded on a rail 20 and transferred to a drying chamber, and then is loaded at a high temperature of about 56 to 120 ° C This method is disadvantageous in that the raw timber to be treated is collectively packed in a hot air device or a furnace and the dried wood after drying is collectively collected.

As described above, in order to commercialize the pest control tree considering the characteristics of the domestic forest resources and the difficulty in using the pest damage tree, it is necessary to adopt a method of directly converting into fuel by introducing various commercialization processes through a cutting process as a wood chip form In the case of processing and producing wood chips or the like by using pine rehabilitation damage trees or pest damage trees such as oak tree shrubs which are the object of the present invention in the present invention, it takes a long time to produce products using the conventional artificial drying furnace as shown in Fig. There is no economical effect as compared with the added value used because of the disadvantage that it is costly inefficiency and can not be continuously produced. On the other hand, there is a need for a method that can expect cost effectiveness as a result of minimizing the time required for manufacturing and continuously producing the same.

Furthermore, in order to maximize the thermal efficiency characteristics of the fuel product, it is necessary to find a way to improve the fuel efficiency by making the composite material by mixing the pesticide tree and another material, and when it is finally applied to the industry, It is necessary to take measures to make fuel directly without needing to control by consuming expensive neck separately.

Therefore, the present inventors have found that, in place of the conventional drying furnace, which has problems such as long-time processing time and collective treatment material recovery in order to commercialize a pest-resistant tree, which is difficult to treat in woody biomass, as a high-efficiency fuel, The present inventors have developed a continuous type rapid wood thermal processing apparatus capable of continuously producing a high-efficiency fuel product through a rapid high-temperature heat treatment process, and using the same to provide a method of highly efficient fueling of a pest-damaged tree.

The rotary drum is rotatably mounted on a horizontal rotary shaft.

The method may further include transferring the woody material from the raw hopper for storing the small-sized woody material by using a conveyor belt, and inputting the woody material into the input member of the thermal processing apparatus.

Further, the method may further comprise the step of pulverizing the lignocellulosic material, which has undergone the thermal processing, in a powder form by a crusher after the lumber material is taken out from the rotary drum.
