According to the present invention, in the soot processing apparatus, first, the plant organic fuel is burned in the combustion chamber to generate smoke. Next, this smoke is sent into the smoke drying treatment chamber. And the wood accommodated in the smoke drying process room | chamber is dried with the sent smoke. Thereby, it dries to the wood with a high Young's modulus. That is, the strength is increased by homogenizing and stabilizing individual cells.
Thereafter, the smoke-dried wood is immersed in a mixed solution of a wood treatment (wood protective agent) containing iron as a main component, a wood vinegar solution, and wood tar for 5 minutes. This mixed solution contains a component for preserving and protecting the wood. By immersing wood in this mixed solution, an effective component can be deeply penetrated into the wood. Thereby, the wood by which antiseptic | preservation and ant-proof processing were carried out can be obtained. Further, even when the wood is exposed to rain or the sun, the useful life of the wood can be extended without the active ingredient flowing out from the wood. As a result, wood can be held for a long period of time in any natural environment regardless of soil, water or sea, and wood products can be provided to parks, roads, rivers, harbors, and the like.

An embodiment of the present invention will be described below with reference to FIGS.
First, a smoke treatment apparatus for wood 11 according to the present embodiment will be described with reference to FIGS. 2 and 3. The soot treatment device has a soot treatment chamber 2 and a combustion chamber 3.
The combustion chamber 3 is formed by a defined chamber, and a heat source generator (not shown) is provided in this chamber.
A partition wall 10 is provided between the combustion chamber 3 and the smoke processing chamber 2. Electronic control dampers 14 and 18 are arranged on the partition 10 in the vertical direction.
One end side of the soot processing chamber 2 is connected to the combustion chamber 3 via the partition wall 10. Further, the other end side is provided with a carry-in port 6 through which the wood 11 for drying is carried in and out of the smoke processing chamber 2. The soot processing chamber 2 forms a gradient so that the ceiling 1 becomes higher as it moves away from the combustion chamber 3. In this configuration, smoke generated in the combustion chamber 3 is sent from the combustion chamber 3 to the carry-in port 6 along the ceiling 1.
A plurality of smoke pipes 15 for circulating the smoke from the upper part to the lower part are provided on the side wall of the soot processing chamber 2 with a predetermined interval. At the lower part of the smoke pipe 15, there are respectively provided blower fans 17 that convect smoke sent from the upper part upward from below.
Further, a temperature sensor 8 for sensing the temperature in the smoke processing chamber 2 is provided at the center of the side wall of the smoke processing chamber 2. That is, a temperature sensor 21 is provided to control the opening and closing of the electronic dampers 14 and 18 in order to keep the temperature in the smoke processing chamber 2 constant.

Next, the soot processing method of the wood 11 in the soot processing apparatus will be described.
First, a wood 11 having a width of 70 mm, a length of 150 mm, and a height of 12 mm is prepared. Then, the wood 11 is placed on the cart 5 and carried into the soot processing chamber 2 from the carry-in entrance 6 of the soot processing chamber 2. Next, the door 4 of the carry-in port 6 is closed to seal the inside of the smoke processing chamber 2. Thereafter, smoke is generated by burning vegetable organic fuel such as processed cutting waste by a heat source generator (not shown). The generated smoke is sent into the smoke processing chamber 2 from the upper damper 14 provided in the partition wall 10. And the sent smoke is sent from the combustion chamber 3 toward the carry-in port 6 along the ceiling 1 provided with the gradient. Smoke to the ceiling 1 is sent from the upper part to the lower part through the smoke pipe 15. A part is sent into the smoke processing chamber 2 by the blower fan 17. The other part flows along the lower side and is returned to the combustion chamber 3 via the lower damper 18 provided in the partition wall 10. Furthermore, the temperature sensor 21 is set so that the inside of the smoke processing chamber 2 becomes an appropriate temperature. That is, the electronic dampers 14 and 18 provided in the partition wall 10 are operated to replenish moisture by the spray nozzle 23 installed in the upper portion of the smoke treatment chamber 2. Alternatively, when the chimney 24 is installed in the vicinity of the untreated timber and the internal pressure in the smoke processing chamber 2 rises, the exhaust valve 25 below the chimney 24 can be operated to control the internal pressure to be constant. .
The temperature at which the wood 11 is dried in the smoke processing chamber 2 is set as follows. That is, as shown in FIG. 1, the temperature is managed using a temperature sensor 21 provided in the smoke processing chamber 2. Specifically, first, the temperature is raised from room temperature to approximately 100 ° C. within 3 hours. Thereafter, the temperature is gradually lowered to room temperature within 72 hours. Due to the rapid temperature rise, moisture contained in the wood 11 can be released to the outside and dried. Thereafter, the wood 11 can contain organic acids, phenols, carbonyl compounds and the like contained in the smoke component by gradually lowering the temperature.
As a result, the wood 11 can be dried uniformly and the Young's modulus of the wood 11 can be improved. That is, the individual cells inside the wood 11 are made uniform and stabilized to increase the strength. Further, in the case of undried wood 11 such as pine, a large amount of spear flows out after the planar processing. However, by performing the smoke treatment, the essential oil component of the volatiles volatilizes, so that the resin component is solidified and the outflow of the ani can be suppressed.

Next, a method for immersing the smoke-dried wood 11 in the mixed solution will be described.
First, the smoked wood 11 and a mixed solution for preserving and protecting the wood 11 are prepared. That is, the mixed solution contains wood treatment, wood vinegar, and wood tar. Lifetime Wood Treatment (trade name) manufactured by VALHALLA WOOD PRES VATIVES (Canada) contains iron as a main component and many other herbal plant extracts.
In addition to acetic acid and methanol, the pyroligneous acid solution contains various types of components such as various fatty acids and esters thereof, lactels, alcohols, aldehydes, ketones, ammonia, and toluene.
Furthermore, wood tar is a black-brown oily substance produced by dry distillation of the wood 11. Contains hydrocarbons, phenols and acetic acid.
When the wood treatment is 400 liters, the composition of the mixed solution is 95 liters of wood vinegar and 5 liters of wood tar. Wood treatment is mainly composed of iron and contains many other herbal plant extracts. This iron content is less likely to rot if fused with the cunning of the wood 11. Moreover, these components are harmless to the human body and have no environmental pollution.
Furthermore, wood vinegar is often used as a coating agent for the wood 11 as an antiseptic and insect repellent, but it is difficult to penetrate into the wood 11 alone. Therefore, by mixing the wood vinegar solution with the wood treatment, approximately 97 to 99.5% of the wood treatment is water, so the wood vinegar solution easily penetrates into the wood 11 together with water. The same can be said for wood tar.
Therefore, when the wood 11 is immersed in the mixed solution for 5 minutes, effective components of the antiseptic and ant repellant contained in the mixed solution penetrate into the wood 11. And gradually, the wood 11 becomes silver white. Therefore, even if exposed to rain or the sun, the active ingredient that has penetrated into the interior penetrates more into the interior and does not flow out of the wood.
As a result, after the wood 11 is smoked, it is immersed in a mixed solution of the wood 11 protective agent, wood vinegar and wood tar. Thereby, it is possible to hold the timber 11 for a long period of time in any natural environment, whether in the soil, underwater or underwater, and to provide wooden products for parks, roads, rivers, harbors, and the like.
