  Embodiments of the present invention considered to be suitable will be briefly described with reference to the drawings.

The present inventor has a problem in the moisture content of the oil adsorbent as a cause of the above-described conventional problem (a problem that hardly absorbs oil that has flowed out to the water surface in actual use and does not fully perform its function). I thought that.

In other words, oil adsorbents are usually stored for a long period of time and are used in emergencies. As a storage method, it is common to store them in a bag (plastic bag, hemp bag, etc.). It is. This is essentially an oil adsorbent, since it has a performance that shed water adsorbs oil is premised, when storing oil adsorbent sucks moisture as possible is oil adsorbent despite it must be prevented, because no consideration of the water absorption during the preservation at all, it is has become the rough storage method as described above, therefore, in reality the oil adsorber during storage It would saturated with humidity and water vapor (confirmed this point), thus, the oil adsorbent while being stored for a long period of time, in the water content is increased than the time of manufacture, its function well in practical usage situation I thought that I couldn't do it.

  Therefore, the invention according to claim 1 stores the oil adsorbing body 3 in a container 4 that is not ventilated and hermetically sealed.

From this configuration, the oil adsorbent 3 having a low water content can be stored for a long period of time (for example, it can be stored so that the water content does not increase due to moisture, etc. over time), and the oil adsorbent 3 can be removed from the container 4 at any time. In this case, a good storage state that can exhibit a good function is obtained.

  Further, in the invention according to claim 2, the oil adsorbing body 3 is housed in a container 4 that does not vent and the container 4 is vacuum-treated, and then the container 4 is sealed and stored. In the third aspect of the invention, the oil adsorber 3 is stored in a container 4 that does not vent together with an inert gas (for example, nitrogen gas), and then the container 4 is sealed and stored. An environment that is difficult to touch is obtained, and therefore, even better long-term storage is possible (storage that prevents moisture content from increasing with time), and because the oxygen concentration is low, for example, the oil adsorbent 3 It is possible to prevent as much as possible the occurrence of feared spontaneous ignition when it is made of a material that easily ignites (carbon material, etc.).

  Specific embodiments of the present invention will be described with reference to the drawings.

  The present embodiment is a method for storing the oil adsorbent 3 that adsorbs oil.

In this embodiment , the oil adsorbing body 3 is accommodated in the bag body 2.

Specifically, the oil adsorbent 3 is rice husk charcoal (carbonized husk) or rice husk (uncarbonized rice husk), and has a water content of 20% (weight) or less by heat treatment.

  The rice husk charcoal according to the present embodiment is carbonized by indirect heating of a carbonization carbonization apparatus (a carbonization method in which rice husk is stored in a drum in which heated gas is arranged and carbonized), and cooling after carbonization is also indirect. It is cooled by cooling (a cooling method for cooling by storing rice husk charcoal in a drum in which cooling water is arranged in the surroundings).

  Therefore, the rice husk charcoal obtained in this way has a shape and volume substantially equivalent to those of rice husk and has a large surface area, so that it exhibits excellent oil adsorption performance and excellent water floating performance. It will be.

Moreover, the rice husk charcoal or rice husk which comprises the oil adsorption body 3 has the outstanding oil adsorption performance and the outstanding water floating performance by making water content 20% or less by heat processing (refer FIG. 1, 2). ).

About This oil adsorber definitive moisture content and oil adsorption is confirmed by experiments, the experimental oil adsorbability and water floating performance for each chaff charcoal are prepared chaff charcoal different water content as an example of an oil adsorbent As shown in FIG. 1, when the water content becomes higher than the water content of about 20% (at the boundary between the water content 22.8% and the water content 34.8% in FIG. 1), each performance is drastically increased. It was confirmed that (oil adsorption performance and water floating performance) decreased. In addition, from this experiment, it was also confirmed that a water content of 20% or less is desirable at the actual use level.

Further, when arranged oil adsorbent 3 composed of water content of 20% or less chaff in oil spilled on water surface, although the oil adsorption performance is inferior compared to the oil adsorbent made of chaff charcoal described above, the chaff By setting the water content to 20% or less, the oil absorption performance and the water floating performance that can sufficiently meet the practical level are obtained.

  This point has been confirmed by experiments, and when rice husks having different moisture contents were prepared and oil adsorption performance and water floating performance were tested for each rice husk, the moisture content was higher than about 20% as shown in FIG. As the rate increased (per boundary between the moisture content 17.8% and the moisture content 31.7% in FIG. 2), it was confirmed that each performance (oil adsorption performance and water floating performance) suddenly decreased. From this experiment, it is considered that a water content of 20% or less is desirable at the actual use level.

In addition, the oil adsorbent 3 made of rice husk requires less energy for commercialization than the oil adsorbent 3 made of rice husk charcoal, which requires a lot of energy for carbonization, and can be manufactured at low cost. Can be reduced as much as possible.

Also, the oil adsorbent 3 made of rice husk has excellent shape retention performance that is less likely to break (collapse) against external pressure than the oil adsorbent 3 made of rice husk charcoal, which is crushed and broken easily. Therefore, volume reduction caused by carbonization can also be suppressed.

In addition, when the oil adsorbent 3 formed by mixing rice husk charcoal having a water content of 20% or less and rice husk having a water content of 20% or less is disposed on the oil flowing out to the water surface, the above-described oil adsorption simply consisting of the rice husk charcoal is described. Similarly the body 3 and simply oil adsorbent 3 composed of chaff, will have a Xiu oil adsorption performance and soo water float performance, further benefits with oil adsorbent 3 composed of chaff charcoal by mixing (Excellent oil adsorption performance, excellent water floating performance, etc.) and merits of oil adsorbent 3 made of rice husk (low cost and excellent shape retention performance ( oil adsorbent 3 made of rice husk charcoal as cushion ) Performance), etc.).

  The definitions of the moisture content, water floating rate, and oil suction rate shown in FIGS. 1 and 2 are as follows.

  The moisture content (weight) is obtained by the following formula based on a measurement principle called a loss on drying method.

Formula ((W−Wo) ÷ W) × 100 = moisture content (MOIST)
W: Initial sample mass Wo: Absolute dry mass The water floating rate is a rate calculated from the amount of what floats and sinks when a predetermined amount is floated on water.

  The oil suction rate is defined as the amount of oil sucked by the standard moisture content (1.1% for rice husk charcoal, 1.0% for rice husk charcoal), and each water content relative to this. It is a rate calculated from the amount of oil inhaled.

Further, the oil adsorbent 3 may be subjected to a surface active treatment according to the use.

That is, by treating the surface of the oil adsorbent 3 with a small amount of a surfactant (for example, sodium alkylbenzene sulfonate), the water adsorbing performance is further reduced while the water absorbing performance is improved while further improving the oil adsorbing performance. The oil adsorber 3 adsorbs moisture as well as an oil film having a small mass.

  Therefore, when the oil film is removed as a finishing process for oil adsorption, it is preferable to use the one subjected to the surface activation process.

If you retract and the oil adsorbent 3 described above in the bag body 2, the case of housing the oil adsorbent 3 composed of all chaff charcoal, and the case and chaff charcoal and chaff housing the oil adsorbent 3 composed of all chaff The mixed oil adsorbent 3 may be stored.

When the oil adsorbent 3 made of all the rice husk charcoal is housed, the oil adsorbent 3 that makes the most of the advantages of the rice husk charcoal, such as excellent oil adsorption performance and excellent water floating performance, can be obtained.

Further, when accommodating the oil adsorbent 3 all made of chaff, so that the benefits of having the chaff such as low cost and soo the shape-retaining performance is utilized maximally.

Further, when accommodating the oil adsorbent 3 composed by mixing rice husk charcoal and chaff, it will combine the benefits of having advantages and chaff with the chaff charcoal described above.

Incidentally, as an oil adsorbent 3 is not limited to the chaff charcoal and chaff may even activated carbon or fibers (natural fibers or chemical fibers), exhibits oil adsorption performance by maintaining a low moisture content, for example, porous Any method can be used as long as the function can be sufficiently exhibited by the storage method described later .

The bag body 2 is formed of a material (woven fabric or non-woven fabric) having water repellency and oil permeability as shown in FIGS. 3 to 5 and is formed in a plan view shape (225 mm × 225 mm). Note that the size and shape of the bag body 2 can be appropriately changed in design. Moreover, this bag body 2 contributes to maintaining the low water content of the oil adsorbing body 3 housed therein by having good water repellency.

  In this embodiment, as shown in FIG. 3, the end portions 2a of the four bag bodies 2 are connected in a separable manner, and the connected portions are separated using a cutting tool such as a scissors. In addition, you may comprise so that a perforation may be provided in this connection part and it can isolate | separate with the force of a hand.

  Further, as shown in FIG. 7, a locking portion 7 that can lock the connecting member 10 such as a hook, a rope, or a connecting ring may be provided at the end of the bag body 2.

  Specifically, the engaging portion 7 is an annular body formed of an appropriate synthetic resin member.

  Specifically, a locking portion 7b that is inserted into and locked to the cylindrical portion 7a is provided at the distal end portion of the wire 7A provided with the cylindrical portion 7a at the base end portion. The ring portion (eyelet) provided at the end 2a is inserted into the ring portion 7b so as to be connected in an annular shape.

  As shown in FIG. 8, the locking portion 7 connects a plurality of bag bodies 2 using a connecting member 10 such as a rope or a connecting ring when an oil fence is formed at a site where oil flows out, In addition, for example, when the oil adsorbing body 3 is arranged at a site where the oil has flowed out or when the oil adsorbing body 3 is collected from the site, it can be used as a site for locking the connecting member 10 such as a hook that is lifted.

  Further, as shown in FIG. 6, the oil adsorbent 3 according to this embodiment described above includes an appropriate oxygen scavenger 5 (for example, Ageless (registered trademark) manufactured by Mitsubishi Gas Chemical Co., Ltd.) and an appropriate desiccant 6 ( For example, it is preserved by being housed and sealed in a container 4 that is not ventilated with Hishibeat (trade name) manufactured by AGC S-Tech Co., Ltd.

  Specifically, the container 4 is a bag made of a non-breathable member (synthetic resin, metal, etc.) (for example, a bag made of barrier nylon / polyethylene manufactured by Meiwa Packs Co., Ltd., polyethylene terephthalate / aluminum / polyethylene). After a predetermined amount of the oil adsorbing body 3, the oxygen scavenger 5 and the desiccant 6 are stored from the opening, the opening is sealed (heat-sealed). The container 4 is not limited to a bag but may be a box-shaped body.

From this storage method, the function of the oxygen scavenger 5 and the desiccant 6 enables good long-term storage of the oil adsorbent 3 having a low water content (for example, the moisture content is higher than 20% due to humidity etc. over time). It can be preserved so that it does not become necessary), and when it is taken out from the container 4 at any time, it exhibits good functions (for example, excellent oil adsorption performance and excellent water floating performance obtained at a moisture content of 20% or less). A good storage state that can be obtained.

Further, for example, when the oil adsorbent 3 is charcoal (chaff husk charcoal), spontaneous ignition during storage that is a concern can be prevented.

  When the oil adsorber 3 is housed and sealed in a container 4 that is not ventilated, the above-described oxygen scavenger 5 and desiccant 6 may be sealed without being stored, or the oil adsorber 3 may not be sealed. It may be stored in a container 4 that does not vent together with an active gas (for example, nitrogen gas / dry inert gas) and sealed, or the oil adsorber 3 may be stored in a container 4 that does not vent and the interior of the container 4 may be sealed. It may be sealed by vacuum processing (for example, vacuum processing by suction with a vacuum pump or the like).

  The container 4 has antistatic properties. It has been confirmed that the above-mentioned materials are not charged with static electricity enough to ignite oil.

  For example, in a scene where oil is adsorbed (for example, an accident site or a gas station), there is a concern that the oil to be adsorbed may be ignited by static electricity charged on a member brought to the site.

  In this regard, this embodiment is extremely useful because there is no fear of an electrostatic fire in which the oil is ignited by static electricity because the container 4 has antistatic properties. The bag body 2 is also preferably made of a member having antistatic properties. However, even if the bag body 2 is not a member having antistatic properties, rice husk charcoal is a material that has low electrical resistance and is difficult to be charged. The bag body 2 is not charged with static electricity to be ignited by touching the rice husk charcoal. That is, although the nonwoven fabric which comprises the bag body 2 is a raw material which carries static electricity, static electricity induction arises and it can remove static electricity by contacting with the conductive rice husk charcoal contained in the inside. Further, since the container 4 can be made into an oxygen barrier and a product with antistatic measures taken, the safety becomes higher. Static induction is a phenomenon in which a charged object having a polarity opposite to that of a charged object is drawn closer to the charged object by bringing the charged object closer to a conductor (chaff). It is caused by the actual movement of charge through the conductor (chaff). Since the electric charge at this time moves so as to cancel the potential difference in the conductor (chaff charcoal), the electric potential in the conductor (chaff charcoal) becomes equipotential.

  An oil processing operation using the oil adsorbing body 3 according to the present embodiment having the above configuration will be described.

  For example, when oil flows into a river or the ocean, the oil adsorbent 3 is taken out from the storage container 4 and used.

Specifically, as shown in FIG. 8, an oil that connects a plurality of bags 2 containing oil adsorbers 3 using a connecting member 10 (rope) to suppress further outflow of oil that has flowed out to the surface of the water. Use as a fence. Since the connecting portions between the bag bodies 2 are bent, the contact area with the water surface is maintained corresponding to the shape change (waves) of the water surface, which functions well as an oil fence.

  In this case, if necessary, the oil retained by the oil fence formed by the oil adsorbing body 3 is adsorbed by arranging another oil adsorbing body 3.

  Thereafter, when the oil adsorbing body 3 that has adsorbed the oil is recovered, the oil adsorbing body 3 can be recovered using the recovery rod 11 as shown in FIG. A connecting member 10 such as a hook (not shown) is locked to a locking portion 7 provided at the end of the bag body 2 and is lifted and collected.

  Further, as another oil processing operation using the oil adsorbing body 3 according to the present embodiment, as shown in FIG. 10, the oil that has flowed into the U-shaped groove 12 by cutting the continuous portions of the bag bodies 2. Can be adsorbed, and oil such as oil leaked from various mechanical devices can be adsorbed.

In the present embodiment, although a case of processing the oil with an oil adsorbent 3 housed in the bag body 2, if the oil adsorbent 3 (the chaff moisture content below 20% charcoal or rice husk) You may make it spray on oil directly.

  As described above, in this embodiment, the oil adsorbent 3 can be maintained in a state of always exhibiting excellent oil adsorbing performance and excellent water floating performance. It will surely exhibit excellent oil adsorption performance and excellent water floating performance.

Furthermore, this embodiment can prevent spontaneous ignition during storage, which is a concern when the oil adsorbent 3 is charcoal (chaff husk charcoal), for example.

  Specifically, when preserving charcoal (rice husk charcoal), which is generally a flammable solid, spontaneous ignition may occur when the temperature rises in an oxygen atmosphere, especially with low moisture content. In this respect, according to the present embodiment, the oxygen absorber 5 is housed in the container 4 together with the oil adsorbent 3 so that there is no oxygen that becomes a component of spontaneous ignition, so that spontaneous ignition can occur. It can be prevented as much as possible.

Moreover, since the present Example employ | adopted the porous oil adsorption body 3 as the oil adsorption body 3, it can maintain the low moisture content with a high oil adsorption capability, and always exhibits the favorable oil adsorption capability.

Further, in this embodiment, the oil adsorbent 3 having a water content of 20% or less is used as the oil adsorbent 3, and actually, for example, the oil adsorbent 3 having a water content of 20% or less is used as oil that has flowed out to the water surface. When arranged, the oil can be adsorbed instantly and in a large amount, and the oil on the water surface can be adsorbed efficiently and satisfactorily because it floats well in water.

Further, this embodiment, the oil adsorbent 3, the water content of 20% or less chaff charcoal, because an oil adsorbent 3 composed by mixing one or both either water content of 20% or less chaff, the following There will be an effect.

That is, when the oil adsorbent 3 made of rice husk charcoal having a water content of 20% or less is disposed on the oil that has flowed out to the surface of the water, excellent oil adsorbing performance (lipophilic performance) that adsorbs oil instantaneously and in large quantities is obtained. In addition, it exhibits excellent water floating performance (water repellent performance) that floats well in water, so that the oil on the water surface can be adsorbed efficiently and satisfactorily. Rice husk charcoal is porous and has excellent oil adsorption performance.

Moreover, the oil adsorbent 3 made of rice husk charcoal also has a deodorizing effect, and can also deodorize the odor of the adsorbed oil.

Therefore, the oil adsorbent 3 made of rice husk charcoal having a water content of 20% or less has excellent oil adsorbing performance and excellent water floating performance, so that oil that has flowed out to the water surface is particularly treated. It becomes effective when. Of course, it is also effective when processing oil such as oil leaked from various mechanical devices.

Further, in the present embodiment, since the oil adsorbent 3 is subjected to surface active treatment, for example, an oil film formed of oil that has flowed out to the water surface can be removed well.

That is, as described above, the oil adsorbent 3 made of rice husk charcoal or rice husk having a low water content has excellent oil adsorption performance (lipophilic performance) and excellent water floating performance (water repellency performance). The oil spilled on the water surface can be adsorbed instantaneously, but in reality, it is difficult to adsorb even the oil film formed on the water surface.

  This is because an oil film having a small mass is repelled due to excellent water floating performance (water repellent performance).

In this respect, in this embodiment, the oil adsorbent 3 is subjected to a surface active treatment, thereby further adsorbing the oil film by reducing the water repellency and improving the water absorption performance while improving the oil adsorption performance. can do.
