Description

  The present invention relates to a method for extracting bound water that extracts bound water containing a tree component contained in a cell from a tree in which a torus of a closed wall hole of the cell is broken.

  A tree component extracted from a tree is known to have a component having an action such as sterilization or deodorization. Further, the bound water contained in the cells of the tree contains a tree component, and is said to be effective for mental or physical stress, bronchial asthma, atopic dermatitis and the like. The combined water is extracted from the trees, and the components of the trees are extracted from the combined water and used for such treatment.

  Conventionally, as a method for extracting a tree component, a small tree is put in a container filled with water and boiled, and an essential oil containing the tree component is extracted by applying pressure. However, this method cannot extract bound water.

  This is because the perimeter wall hole of the cell is opened as a water channel before logging, but when the tree is cut and cut, this channel is closed and the combined water stored in the cell is released to the outside. It is because it inhibits coming out.

  More specifically, as shown in FIG. 5 (a), the tree has a peripheral wall hole 21 between adjacent cells 20, and this peripheral wall hole 21 serves as a water channel for moisture necessary for growth. Sucking up. In the tree at the time of growth, the marginal wall hole 21 functions as a water passage when moisture passes through the portion of the Margo 22 with the Margo 22 which is a thin mesh-like wall hole membrane supporting the torus 23.

  However, when the tree is cut down, the cells facing the cut surface have a state where the torus 23 closes the opening of the peripheral wall hole 21 and is called a closed peripheral wall hole, as shown in FIG. End up. This is because the trees try to retain moisture inside the cells 20 that are cut and exposed. It is very difficult to extract the bound water from the trees in such a state.

  As described above, the conventional tree component extraction method is performed in a state in which the cells on the surface of the tree as a small piece are in the form of closed wall holes, so that the combined water cannot be extracted from the tree. There is also a problem that the bound water is altered by heating.

  Moreover, since the tree is made into small pieces, boiled and pressurized, the extracted tree is in a state where it cannot be used elsewhere. Therefore, the extracted tree can only be used as waste, which is not preferable from the viewpoint of environmental conservation.

Non-Patent Documents 1 and 2 describe a technique for separating the bound water in the cell and taking it out of the cell wall, and selectively destroying the torus by the underwater shock wave of the tree that has become a closed wall hole. A method for treating timber using timber in which a torus is selectively destroyed by the underwater shock wave is described in Patent Document 1, but a technique for extracting bound water from a tree in which the torus is destroyed has not yet been developed. Not.
Therefore, the present invention is capable of extracting bound water at room temperature from a tree in which the torus of a part or all of the walls of the wall is destroyed, and allowing the secondary use of the extracted tree. It aims at providing the extraction method of water.

  The method for extracting bound water according to the present invention is a method for extracting bound water contained in a cell of a tree, wherein a shock wave is applied to the tree, and a part or all of the peripheral wall pores of the cell are exposed. After the torus is destroyed, the tree is stored in a sealed container, the gas inside the sealed container is sucked at a negative pressure, and the bound water contained in the sucked gas is collected in a storage container. .

  A known technique separates the bound water containing the tree components contained in the cells of the tree by a shock wave and puts it out of the cell wall, destroying part or all of the torus of the tree cells, and this torus is destroyed. The stored water is stored in the sealed container, and the gas inside the sealed container is sucked by the negative pressure means, so that the bound water is sucked out from the opening of the edge wall of the tree where the torus is broken. The combined water sucked out is sucked out together with the gas from the sealed container. And the combined water contained in the sucked-out gas is collected and stored in the storage container. This shock wave can be an underwater shock wave generated by exploding explosives in water.

  Here, in the extraction method, after extracting the bound water with the negative pressure, the tree is immersed in water, subjected to ultrasonic vibration, and then stored in the sealed container again, and suction is performed with the negative pressure. It is desirable.

  A tree from which bound water has been extracted cannot extract all of the bound water because the tree components contained in the bound water adhere to the cell wall during extraction. Therefore, the tree from which this combined water has been extracted is immersed in the stored water, and this water is vibrated by the ultrasonic wave generating means, so that this vibration is transmitted to the tree, washing out the tree components attached to the cell wall, and again The tree is stored in a sealed container, and the bound water is sucked out by a negative pressure means. Thereby, extraction of the joint water containing a tree component can be performed, without making it remain.

In this way, by sucking the gas inside the sealed container from the tree where the torus was destroyed by negative pressure means, the bound water is sucked out from the opening of the edge wall of the tree where the torus was destroyed. Extraction of water is possible.
In addition, it is possible to extract the bound water without making small pieces, and the tree from which the bound water has been extracted has a hole in the cut surface and a void in the cell. Easy to penetrate powder. Therefore, it can be used secondarily as highly functional wood.
Moreover, in the conventional extraction method, since the wood piece is boiled, the combined water causes component alteration due to heat, but since it can be performed at room temperature, there is no fear of component alteration.

(2) The binding water is left in the tree by providing the container from which the bound water is extracted with the sealed container and the container capable of immersing the stored water in the stored water and the ultrasonic wave generating means for vibrating the water in the container. Extraction can be performed without any problem, and efficient extraction of bound water is possible.

The first storage container 5, the cooling device 6 connected to the first storage container 5 for cooling the gas discharged from the first storage container 5, and the gas cooled by the cooling device 6 And a second storage container 7 for collecting the combined water.

  Furthermore, the combined water extraction apparatus 1 according to the embodiment of the present invention stores the tree from which the combined water is extracted in the sealed container 2 in the cleaning container 8 that can be immersed in the stored water and the cleaning container 8. And an ultrasonic generator 9 which is an ultrasonic generator for applying vibration to the water.

  The sealed container 2 is a container having a size enough to store a tree cut into a diameter of about 5 cm to 10 cm and a length of about 50 cm to 1 m. All trees can be used as the trees stored in the hermetic container 2, and a process such as destroying a part or all of the torus of the peripheral wall hole is performed in advance by a known technique. The hermetic container 2 has a hermetic property that allows the inside to be at a pressure of about 0.08 MPa by sucking out the air inside by the vacuum pump 3.

  The size of the sealed container 2 can be determined as appropriate depending on the tree to be stored and the degree of suction force of the vacuum pump 3.

  The micro mist separator 4 is connected to the sealed container 2. The micro mist separator 4 incorporates a mesh filter in the air passage so as to remove gaseous impurities sucked from the sealed container 2. A mesh filter having a gap of 0.1 μm to 0.2 μm can be used, and has a function of removing impurities such as extremely small pieces of wood and dust contained in the gas sucked from the sealed container 2. .

  The first storage container 5 is a sealed container connected to the introduction pipe 5 a from the micro mist separator 4 and the lead-out pipe 5 b to the cooling device 6. The gas sucked in by the vacuum pump 3 and sucked out from the sealed container 2 is introduced into the first storage container 5 through the introduction pipe 5a. The bound water contained in the gas is collected so as to adhere to the inner wall surface or the bottom surface of the first storage container 5, and when the amount of adhesion increases, it is dropped and stored at the bottom. Then, the gas inside the first storage container 5 flows to the cooling device 6 through the outlet pipe 5b.

  The vacuum pump 3 is connected to the second storage container 7 via a lead-out pipe 7b. The vacuum pump 3 desirably has a larger suction force, but may be about 0.07 KPa.

  The washing container 8 is a metal container having a size capable of immersing a tree from which bound water has been extracted in the sealed container 2 in prestored water. The water is preferably pure water so that dust contained in the water does not adhere to the tree and the bound water does not change in quality.

  The ultrasonic generator 9 is a device that generates a sound wave of about 20 KHz to 40 KHz. The ultrasonic generator 9 is connected to the cleaning container 8 via a metallic transmission means 9a. By this transmission means 9a, the ultrasonic waves generated by the ultrasonic generator 9 are transmitted as ultrasonic vibrations from the outside of the cleaning container 8 to the pure water inside. This ultrasonic vibration is transmitted to the tree through the pure water stored in the cleaning container 8.

  When the transmission means 9a directly vibrates the pure water stored in the cleaning container 8, the cleaning container 8 may be made of any material as long as it can store pure water, even if it is not made of metal. It may be formed.

  The operation and use state of the combined water extraction apparatus according to the embodiment of the present invention configured as described above will be described with reference to FIGS. FIG. 3 is a diagram for explaining that the bound water contained in the cells of the tree is separated by the underwater shock wave. FIG. 4 is a diagram for explaining a tree in which a torus that closes a framed wall hole is destroyed.

  First, an underwater shock wave is applied to the tree 13 cut into a diameter of about 5 cm to 10 cm and a length of about 50 cm to 1 m with the shock wave generator 10 shown in FIG. This underwater shock wave is a shock wave generated by exploding the explosive 12 in water. Water 11 is stored in the container 10a, the tree 13 is immersed in the stored container 10a, and the container 10a is sealed with the lid 10b. Next, the explosive 12 is exploded in water.

  The underwater shock wave applied to the tree 13 is desirably generated by detonating multiple times while changing the direction of the tree 13 facing the explosive 12. In this Embodiment, it performed 6 times, rotating the tree 13. FIG.

  As shown in FIG. 3, the underwater shock wave separates the bound water 24 in the tree cell 20 and exits from the cell wall 25. Further, due to this underwater shock wave, the torus that has closed the opening of the edge wall hole 21 of the cell 20 of the tree of the tree in the state shown in FIG. 5B is destroyed as shown in FIG. The framed wall hole 21 is secured as a water passage.

  The tree which gave this underwater shock wave is stored in the airtight container 2 shown by FIG. Then, the cooling device 6 is operated.

  Next, the operation of the vacuum pump 3 is started. By the suction of the vacuum pump 3, the atmospheric pressure in the sealed container 2 is lowered.

  As the atmospheric pressure in the sealed container 2 decreases, the bound water in the cells of the tree in which the torus of the peripheral wall hole has been destroyed is sucked out of the tree from the open peripheral wall hole.

  When the combined water sucked out with the gas passes through the micro mist separator 4, extremely small pieces of wood, dust, dust, and the like are removed, and flows into the first storage container 5 through the introduction pipe 5 a.

  The combined water contained in the sucked-out gas is collected so as to adhere to the inner wall surface or the bottom surface of the first storage container 5, and when the amount of adhesion increases, it is dripped and stored at the bottom. Then, the gas inside the first storage container 5 flows to the cooling device 6 through the outlet pipe 5b.

  By cooling the gas flowing into the cooling device 6, the bound water contained in the gas that could not be collected in the first storage container 5 is liquefied.

  The liquefied combined water is introduced into the second storage container 7 through the introduction pipe 7a and collected together with the gas. Then, the gas reaches the vacuum pump 3 through the outlet pipe 7b and is exhausted.

  The tree from which the combined water has been extracted in this manner is taken out from the sealed container 2 and immersed in the cleaning container 8 in which pure water is stored in advance.

  This is because, in a tree from which bound water has been extracted, the tree components contained in the bound water adhere to the cell wall during the extraction, so that all of the bound water cannot be extracted. Therefore, the tree from which the combined water has been extracted is immersed in a cleaning container 8 in which pure water is stored, and vibration is applied to the cleaning container 8 by the ultrasonic generator 9, whereby this vibration is transmitted to the tree, and the cell wall Wash out the tree components adhering to and secure a passage to suck out the bound water.

  The ultrasonic generator 9 is operated to generate ultrasonic waves, and the trees in the cleaning container 8 are cleaned. This washing is performed for about 5 minutes.

  Then, the cleaned tree is stored in the sealed container 2 again, and the combined water is extracted by suction of the vacuum pump 3.

  In this way, the bound water can be extracted from the tree that has been subjected to the treatment for destroying part or all of the torus of the walled hole.

  Using the combined water extraction device of the present embodiment, a cedar wood having a diameter of 70 mm is cut into a length of 600 mm, and treated with an underwater shock wave is placed in a sealed container 2, and a vacuum pump 3 Was put into operation. As a result, 140 ml of bound water per hour could be extracted into the first storage container 5 and the second storage container 7. Further, the extracted cedar material was put into a cleaning container 8 storing pure water, and ultrasonic vibration was applied to the cedar material from the ultrasonic generator 9 for about 5 minutes. Thereafter, the cedar material was put into the sealed container 2 again, and the vacuum pump 3 was operated. As a result, 150 ml of combined water containing pure water could be extracted into the first storage container 5 and the second storage container 7.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, The micro mist separator 4 is between the airtight container 2 and the 1st storage container 5. As shown in FIG. However, it is also possible to connect a micro mist separator after the first storage container in order to avoid the influence of bound water adhering to the mesh filter of the micro mist separator.
