Description

本発明は、長さおよび太さが互いに異なる２種の柱状体を分別する柱状体分別方法および柱状体分別装置に関する。
本願は、２０１２年３月１９日に、日本に出願された特願２０１２−０６２１１４号に基づき優先権を主張し、その内容をここに援用する。The present invention relates to a columnar body sorting method and a columnar body sorting apparatus for sorting two types of columnar bodies having different lengths and thicknesses.
This application claims priority on March 19, 2012 based on Japanese Patent Application No. 2012-062114 for which it applied to Japan, and uses the content for it here.

固体触媒を用いた反応においては、通常、反応器の内部に、固体触媒の柱状体と、反応を調整するための希釈用の柱状体とが充填されることがある。反応活性が低下した固体触媒は、交換のために反応器から取り出され、近年では廃棄処分されずに再生されてリサイクルされる。しかし、使用済みの固体触媒をリサイクルするためには、希釈用の柱状体と分別する必要がある。
２種の柱状体同士を分別する装置としては、例えば、円筒状の篩と、その篩を回転させる駆動手段と、前記篩の内周面側に２種の柱状体を供給する供給手段とを備えるものが知られている（特許文献１）。
また、柱状体を分別する篩としては、その開口孔が丸孔のものが一般的であるが、特許文献２には、六角孔、三角孔、四角孔等の開口孔が開示されている（特許文献２）。In a reaction using a solid catalyst, a solid catalyst columnar body and a diluting columnar body for adjusting the reaction are usually filled in the reactor. The solid catalyst having a reduced reaction activity is taken out of the reactor for exchange, and in recent years, it is regenerated and recycled without being disposed of. However, in order to recycle the used solid catalyst, it is necessary to separate it from the columnar body for dilution.
As an apparatus for separating two kinds of columnar bodies, for example, a cylindrical sieve, a driving means for rotating the sieve, and a supply means for supplying two kinds of columnar bodies to the inner peripheral surface side of the sieve are provided. What is provided is known (patent document 1).
In addition, as a sieve for separating columnar bodies, those having round holes are generally used, but Patent Document 2 discloses opening holes such as hexagonal holes, triangular holes, and square holes ( Patent Document 2).

ところで、上記固体触媒の柱状体と希釈用の柱状体とは、長さおよび太さの違いが僅かでほぼ同じ形状になっている場合がある。そのような場合、特許文献１に記載の分別装置では、２種の柱状体同士を分別することは困難であった。また、長さおよび太さの違いが僅かな２種の柱状体同士の分別に特許文献２に記載の篩を用いても、充分に分別できなかった。
本発明は、長さおよび太さが互いに異なる２種の柱状体同士、特に、長さおよび直径の違いが僅かな２種の円柱体同士を充分に分別できる柱状体分別方法および柱状体分別装置を提供することを目的とする。By the way, the columnar body of the solid catalyst and the columnar body for dilution may have almost the same shape with a slight difference in length and thickness. In such a case, it is difficult for the sorting device described in Patent Document 1 to sort the two types of columnar bodies. Moreover, even if the sieve described in Patent Document 2 was used to separate the two types of columnar bodies having a slight difference in length and thickness, it could not be sufficiently separated.
The present invention relates to a columnar body separation method and a columnar body separation apparatus capable of sufficiently separating two types of columnar bodies having different lengths and thicknesses, in particular, two types of columnar bodies having a slight difference in length and diameter. The purpose is to provide.

また、上記柱状体分別装置は１個である必要はなく、２個以上を直列に接続しても構わない。
また、篩は必ずしも円筒状である必要はなく、平板状であってもよい。平板状の篩の場合には、該篩が傾斜し且つ振動することが好ましい。In addition, this invention is not limited to the said embodiment. For example, the columnar body supplying means may be one that drops from the tank due to the weight of two types of columnar bodies when the valve attached to the lower part of the tank is opened and supplies it to the cylindrical sieve. The clogging removing means may be arranged in a comb shape so that the plurality of bumping bars correspond to the opening holes.
Moreover, the columnar body sorting apparatus of the present invention may not include the columnar body supply unit, the clogging removal unit, and the scale removal unit. If the columnar body supply means is not provided, the operator only needs to supply two types of columnar bodies to the cylindrical sieve. If the columnar body supply means is not provided, the operator temporarily stops and the operator is clogged. If the scale removing means is not provided, the apparatus is temporarily stopped and the operator can remove the scale.
Moreover, the said columnar body separation apparatus does not need to be one, and may connect two or more in series.

また、長穴形状の開口孔は、六角形状の開口孔と同様に、分別性が高くなることから、好ましい。ただし、長穴形状とは、開口孔Ｈ６のような、第１の辺Ｓ１と第２の辺Ｓ２とが互いに平行な直線状になっている必要はなく、例えば、楕円形状も長穴形状に含まれる。The opening holes formed in the sieve are not limited to the hexagonal ones, but may be opening holes H 2 to H 13 as shown in FIG.

The opening hole H 1 of the dimensions of the cylindrical sieve 10 used are those satisfying the (a) ~ (d). That is,
(A) A pair of opposite sides (side S 1 and side S 2 , side S 3 and side S 4 , side S 5 and side S 6 ) of the opening hole H 1 are parallel and have the same length. ing.
Distance W between the side S 1 and the side S 2 of (b) opening hole H 1 is greater than the diameter and length of the catalyst cylinder and is smaller than the diameter of the spring.
(C) The length L A of the side S 1 and the maximum length L B of the hexagon in the Y direction are inserted into the opening hole H 1 so that the axial direction of the catalyst cylinder is parallel to the Z direction. When the rotation axis P is provided at the center in the axial direction, the length Q of the catalyst cylinder can be rotated along the YZ plane.
(D) L A and L B have such a length that they cannot pass through the opening hole H 1 when the spring is disposed on the opening hole H 1 so that the axial direction thereof is along the X direction.
Openings H 1 of the present embodiment, as shown in FIG. 18, the sequence and Y directions of the array of X-direction are both arranged in series.
Specifically, the cylinders are separated by supplying two types of cylinders to the inner peripheral surface side of the cylindrical sieve 10 using the columnar body supplying means 30 while rotating the cylindrical sieve 10 using the driving means 20. spring remains in the cylindrical sieve 10, the catalyst cylinder was fractionated to pass through the opening hole H 1.
And, the mass of the catalyst cylinder passing through the cylindrical sieve among the catalyst cylinders supplied to the cylindrical sieve is a, and the mass of the catalyst cylinder remaining in the cylindrical sieve is b,
(Proportion A of the catalyst column that passed through the cylindrical sieve A) = a / (a + b) × 100 [% by mass]
(Proportion B of catalyst cylinder remaining in cylindrical sieve) = b / (a + b) × 100 [mass%]
The mass of the spring that has passed through the cylindrical sieve among the springs supplied to the cylindrical sieve is c, and the mass of the spring remaining in the cylindrical sieve is d,
(Proportion C of the spring that passed through the cylindrical sieve C) = c / (c + d) × 100 [mass%]
(Proportion D of spring remaining in cylindrical sieve D) = d / (c + d) × 100 [mass%]
The fractionation was evaluated using the following classification index E.
(Separability index E) = (ratio A of the catalyst column that has passed through the cylindrical sieve) / 100 × (ratio D of the spring remaining in the cylindrical sieve) / 100
Here, the separability index E is the amount that the object to be passed (catalyst column) has passed (closer to 100%) x the amount that the object (spring) that wants to remain (closer to 100%) is better. Therefore, the closer to 1, the better. If it was 0.90 or more, it was judged that the separability was good. The separability index E is more preferably 0.95 or more.
Further, the ratio% of the number of clogged open holes to the total number of open holes in the cylindrical sieve was also measured. These results are shown in Table 1.
