Description

この発明は、例えば、バイオディーゼル燃料の製造工程における廃食用油のエステル分解反応において、反応物を撹拌する撹拌装置に関する。   The present invention relates to an agitation device for agitating a reaction product in an ester decomposition reaction of waste edible oil in a production process of biodiesel fuel.

上記エステル分解反応においては、廃食用油１単位とメタノール３単位から、カルボキシル基を有する炭化水素３単位とグリセリン１単位を生成する反応であり、可逆的な反応である。   The ester decomposition reaction is a reaction that generates 3 units of a hydrocarbon having a carboxyl group and 1 unit of glycerin from 1 unit of waste edible oil and 3 units of methanol, and is a reversible reaction.

この種の撹拌装置としては、反応容器が、垂直円筒状胴壁を有しており、胴壁の軸線上を垂直状回転軸がのびており、回転軸に撹拌羽が固定されているものが知られている（例えば、特許文献１参照。）。   As a stirring apparatus of this type, a reaction vessel has a vertical cylindrical body wall, a vertical rotating shaft extends on the axis of the body wall, and a stirring blade is fixed to the rotating shaft. (For example, refer to Patent Document 1).

また、他の撹拌装置としては、反応容器内が、容器胴壁内面に固定された仕切壁によつて、複数段の反応室に仕切られ、各段の反応室内に撹拌羽が配置されているものが知られている（例えば、特許文献２参照。）。   As another stirring device, the inside of the reaction vessel is partitioned into a plurality of stages of reaction chambers by a partition wall fixed to the inner surface of the container body wall, and stirring blades are arranged in the reaction chambers of the respective stages. The thing is known (for example, refer patent document 2).

特許文献１に記載の撹拌装置では、反応物が反応容器に投入された時点で、反応容器内の反応物の濃度が常に均一化されるため、反応物の濃度を高い状態に保つことが困難である。   In the stirring apparatus described in Patent Document 1, since the concentration of the reactant in the reaction vessel is always uniformed when the reactant is charged into the reaction vessel, it is difficult to keep the concentration of the reactant in a high state. It is.

また、未反応の反応物が反応容器が排出されてしまうことがある。   Moreover, unreacted reactants may be discharged from the reaction vessel.

特許文献２に記載の撹拌装置では、反応物が各段の反応室を順次通過させられることにより、徐々に反応物の濃度が低下させられせることにより、特許文献１に記載の装置の欠点は、解消されるが、仕切壁が容器胴壁内面に固定されているため、装置がコスト高となり、メンテナンスが困難である。
実公昭６１−４０３３９号公報 特開平４−２２５８２６号公報 In the stirrer described in Patent Document 2, the reactants are sequentially passed through the reaction chambers of each stage, so that the concentration of the reactants is gradually reduced. However, since the partition wall is fixed to the inner surface of the container body wall, the cost of the apparatus is high and maintenance is difficult.
Japanese Utility Model Publication No. 61-40339 JP-A-4-225826

この発明の目的は、反応容器内を複数段の反応室に区画することが出来るにも拘わらず、装置のコストの上昇を抑制することができ、メンテナンスの容易な撹拌装置を提供することにある。   An object of the present invention is to provide an agitation apparatus that can suppress an increase in the cost of the apparatus and can be easily maintained even though the inside of the reaction vessel can be divided into a plurality of reaction chambers. .

この発明による撹拌装置は、反応容器が、垂直円筒状胴壁を有しており、胴壁の軸線上を垂直状回転軸がのびており、回転軸の長さ方向に所定間隔をおいた複数か所に、水平状第１円板および第２円板が交互に固定されており、両円板のそれぞれの上面および下面の少なくともいずれか一方に、その周方向に間隔をおいて複数の撹拌羽が固定されており、胴壁内周面および第１円板外周面間を反応物の流通を阻止する間隙となすように第１円板外周面が形成されており、第１円板外周面より半径方向内側に反応物流路が形成されており、胴壁内周面および第２円板外周面間を反応物の流通を許容する間隙となすように第２円板外周面が形成されているものである。   In the stirring apparatus according to the present invention, the reaction vessel has a vertical cylindrical body wall, and a vertical rotation shaft extends on the axis of the body wall, and a plurality of the predetermined intervals in the length direction of the rotation shaft. The horizontal first disk and the second disk are alternately fixed to each other, and a plurality of stirring blades are provided on at least one of the upper and lower surfaces of each of the disks at intervals in the circumferential direction. Is fixed, and the first disc outer peripheral surface is formed so as to form a gap between the inner peripheral surface of the trunk wall and the outer peripheral surface of the first disc so as to prevent the flow of the reactant. A reactant flow path is formed on the inner side in the radial direction, and the second disk outer peripheral surface is formed so that a gap between the inner peripheral surface of the trunk wall and the outer peripheral surface of the second disk is allowed to flow through the reactant. It is what.

この発明による撹拌装置では、反応容器内を複数段に仕切るための円板が回転軸と一体化されているから、装置の解体およびメンテナンスが容易となり、コストの増加分を抑えることができる。   In the stirring device according to the present invention, the disk for partitioning the inside of the reaction vessel into a plurality of stages is integrated with the rotating shaft, so that the device can be easily disassembled and maintained, and an increase in cost can be suppressed.

さらに、第２円板外周面に流れ抵抗強化用環状溝が設けられていると、溝によって、胴壁内周面および第２円板外周面間の間隙を通過する反応物の流れに渦を発生させて、流れの抵抗を大きくすることができる。   Further, when the flow resistance enhancing annular groove is provided on the outer peripheral surface of the second disk, the groove causes a vortex in the flow of the reactant passing through the gap between the inner peripheral surface of the trunk wall and the outer peripheral surface of the second disk. This can increase the flow resistance.

溝の幅は、第２円板の厚みの３分の１以上であることが好ましく、それ以下であると、渦が発生し難くなる。   The width of the groove is preferably at least one third of the thickness of the second disk, and if it is less than that, vortices are less likely to occur.

また、第２円板外周縁部上面および下面の少なくともいずれか一方に複数の流れ抵抗強化用突起が間隔を置いて設けられていると、上記溝と同様に、突起によって、流れに渦を発生させることができる。   If a plurality of flow resistance enhancing projections are provided at intervals on at least one of the upper surface and the lower surface of the outer peripheral edge of the second disk, a vortex is generated in the flow by the projections in the same manner as the groove. Can be made.

突起は、第２円板の周方向から見て、三角形であることが好ましく、このような形状であれば、流れを遮ることができる。突起の高さは、第２円板の厚みの２分の１程度であることが好ましい。   The protrusion is preferably triangular as viewed from the circumferential direction of the second disk, and the flow can be blocked with such a shape. The height of the protrusion is preferably about one half of the thickness of the second disk.

また、第２円板外周面に流れ抵抗強化用面粗さ部が設けられていることが好ましい。   Further, it is preferable that a flow resistance enhancing surface roughness portion is provided on the outer peripheral surface of the second disk.

面粗さ部は、第２円板外周面に細かい傷を無数に付けるように加工することによって形成される。   A surface roughness part is formed by processing so that innumerable fine damage | wounds may be given to the 2nd disc outer peripheral surface.

また、反応物流路の開口面積と、胴壁内周面および第２円板外周面間の間隙の面積とが、反応物入口の面積と等しくなされていることが好ましい。   Moreover, it is preferable that the opening area of the reactant flow path and the area of the gap between the inner peripheral surface of the trunk wall and the outer peripheral surface of the second disc are equal to the area of the reactant inlet.

双方の面積が等しくないと、対応するか所での反応物の流速が相違してしまい、反応物が過剰に混合してしまい、好ましくない。   If the areas of both are not equal, the flow rates of the reactants at the corresponding locations are different, and the reactants are excessively mixed, which is not preferable.

この発明によれば、反応容器内を複数段に反応室に区画することが出来るにも拘わらず、装置のコストの上昇を抑制することができ、メンテナンスの容易な撹拌装置が提供される。   According to this invention, although the inside of the reaction vessel can be divided into reaction chambers in a plurality of stages, an increase in the cost of the apparatus can be suppressed, and an agitation apparatus that is easy to maintain is provided.

この発明の実施の形態を図面を参照しながらつぎに説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１を参照すると、撹拌装置は、反応容器11を備えている。反応容器11は、垂直円筒状胴壁21と、胴壁21の上下端開口に施されているドーム状頂壁22および底壁23よりなる。胴壁21の下端には反応物入口パイプ24が設けられている。胴壁21の上端には反応物出口パイプ25が設けられている。   Referring to FIG. 1, the stirring apparatus includes a reaction vessel 11. The reaction vessel 11 is composed of a vertical cylindrical trunk wall 21, and a dome-like top wall 22 and a bottom wall 23 provided at upper and lower end openings of the trunk wall 21. A reactant inlet pipe 24 is provided at the lower end of the trunk wall 21. A reactant outlet pipe 25 is provided at the upper end of the trunk wall 21.

胴壁21の軸線上を垂直状回転軸26がのびている。回転軸26の長さ方向に間隔をおいた４か所には水平状第１円板31および第２円板32が交互に２つずつ固定されている。第１円板31および第２円板32のそれぞれ上面には、複数の垂直帯板状撹拌羽33（図１では３個である）が等間隔で放射状に固定されている。   A vertical rotation shaft 26 extends on the axis of the body wall 21. Two horizontal first discs 31 and two second discs 32 are alternately fixed at four positions spaced in the length direction of the rotating shaft 26. On each upper surface of the first disk 31 and the second disk 32, a plurality of vertical strip-shaped stirring blades 33 (three in FIG. 1) are fixed radially at equal intervals.

胴壁21に対し頂壁22は着脱自在である。胴壁21から頂壁22を取外せば、回転軸26とともに第１円板31および第２円板32を胴壁21から抜き出すことが可能である。   The top wall 22 is detachable with respect to the trunk wall 21. If the top wall 22 is removed from the body wall 21, the first disk 31 and the second disk 32 together with the rotating shaft 26 can be extracted from the body wall 21.

図２に、第１円板31が示されている。胴壁21内面の内径をＤ0とし、第１円板31の外径をＤ1としたときに、Ｄ0≒Ｄ1である。そのため、胴壁21内面および第１円板31外面の間には、第１円板31の回転はできる間隙はあるが、反応物の流通を阻止しうる間隙となっている。第１円板31の中央部には複数の円弧状反応物流路34（図２では３個である）が形成されている。   FIG. 2 shows the first disc 31. When the inner diameter of the inner surface of the body wall 21 is D0 and the outer diameter of the first disc 31 is D1, D0≈D1. For this reason, there is a gap between the inner surface of the barrel wall 21 and the outer surface of the first disk 31 that allows the rotation of the first disk 31, but it is a gap that can prevent the reactant from flowing. A plurality of arc-shaped reactant flow paths 34 (three in FIG. 2) are formed at the center of the first disk 31.

図３に、第２円板32が示されている。第２円板32の外形をＤ2としたときに、Ｄ0＞Ｄ2である。そのため、胴壁21内面および第２円板32外面間の間隙ｅを反応物は通過できるようになっている。   In FIG. 3, the second disk 32 is shown. When the outer shape of the second disk 32 is D2, D0> D2. Therefore, the reactant can pass through the gap e between the inner surface of the body wall 21 and the outer surface of the second disc 32.

反応物入口パイプ24の横断面積と、複数の反応物流路34（図２では３個である）の合算した横断面積と、胴壁21内面および第２円板32外面間の間隙ｅの横断面積とは、等しく形成されている。また、これらの横断面積は、胴壁21の横断面積の５％未満であることが好ましい。   The cross-sectional area of the reactant inlet pipe 24, the total cross-sectional area of the plurality of reactant flow paths 34 (three in FIG. 2), and the cross-sectional area of the gap e between the inner surface of the body wall 21 and the outer surface of the second disc 32 Are equally formed. Further, these cross-sectional areas are preferably less than 5% of the cross-sectional area of the trunk wall 21.

バイオディーゼル生成過程において、本発明が対象としている化学反応式は、以下の通りである。   In the biodiesel production process, the chemical reaction formula targeted by the present invention is as follows.

廃植物油＋３メタノール⇔３メチルエステル＋グリセリン
反応容器11内に円板によって４つの反応室を形成した場合、図４に、各物質の濃度変化が模式的に示されている。また、比較例として、図５に、冒頭で説明した特許文献１の装置による反応の様子を示す。 Waste vegetable oil + 3 methanol ⇔ 3 methyl ester + glycerin When four reaction chambers are formed in the reaction vessel 11 by discs, FIG. 4 schematically shows changes in the concentration of each substance. Further, as a comparative example, FIG. 5 shows a reaction state by the apparatus of Patent Document 1 described at the beginning.

つぎに、上記撹拌装置の変形例について、様々に説明する。以下の説明において、図１に示す部分と対応する部分には、同一の符号を付して示す。   Next, various modifications of the stirring device will be described. In the following description, parts corresponding to those shown in FIG.

図６では、側方より見て、第１円板31および第２円板32の上面の外周近くに２つの撹拌羽33が、その下面の中央近くに２つの撹拌羽33がそれぞれ設けられている。第１円板31下面の撹拌羽33と、第２円板32上面の撹拌羽33とは、側方より見て、オーバーラップさせられている。   In FIG. 6, when viewed from the side, two stirring blades 33 are provided near the outer periphery of the upper surfaces of the first disk 31 and the second disk 32, and two stirring blades 33 are provided near the center of the lower surface. Yes. The stirring blade 33 on the lower surface of the first disk 31 and the stirring blade 33 on the upper surface of the second disk 32 are overlapped when viewed from the side.

図７では、第１円板31および第２円板32の上面および下面に撹拌羽33が４つずつ設けられている。第１円板31下面の撹拌羽33と、第２円板32上面の撹拌羽33とは、側方より見て、１つ置きに交互にオーバーラップさせられている。撹拌羽の個数および配置パターンは、図６、図７に示す構成に限定せず、適宜変更してもよい。   In FIG. 7, four stirring blades 33 are provided on the upper and lower surfaces of the first disc 31 and the second disc 32, respectively. The stirring blades 33 on the lower surface of the first disk 31 and the stirring blades 33 on the upper surface of the second disk 32 are alternately overlapped as seen from the side. The number and arrangement pattern of the stirring blades are not limited to the configurations shown in FIGS. 6 and 7 and may be changed as appropriate.

図８に示す撹拌羽33は、第１円板31に垂直ではなく、第１円板31の回転方向に向かって倒れるように、所定角度θ1だけ傾斜させられている。このような構成を採用すると、反応室内での上下方向の撹拌が促進される。第１円板31の回転数が大きい場合は、撹拌羽33の傾斜角度θ1を大きくし、回転数が小さい場合は傾斜角度θ1を小さくするように、第１円板31の回転数に応じて傾斜を与える。上記構成は、第２円板32についても採用される。   The stirring blade 33 shown in FIG. 8 is not perpendicular to the first disk 31 but is inclined by a predetermined angle θ 1 so as to fall down in the rotation direction of the first disk 31. Employing such a configuration facilitates vertical stirring in the reaction chamber. When the rotation speed of the first disk 31 is large, the inclination angle θ1 of the stirring blade 33 is increased, and when the rotation speed is small, the inclination angle θ1 is decreased according to the rotation speed of the first disk 31. Give a tilt. The above configuration is also adopted for the second disc 32.

図９に示す撹拌羽33は、第１円板31の半径方向にのびるのではなく、半径方向に対して、所定角度θ2だけ傾斜させられていると、第１円板31の中心部と外周部での撹拌が促進される。この構成についても、第２円板32に適用される。   The stirring blade 33 shown in FIG. 9 does not extend in the radial direction of the first disc 31 but is inclined by a predetermined angle θ2 with respect to the radial direction. Agitation in the part is promoted. This configuration is also applied to the second disk 32.

粘性が大きい反応液の場合は傾斜をもたせた大きめの撹拌羽33を利用し、粘性が小さい場合は傾斜のない小さめの撹拌羽33を利用する。   In the case of a reaction liquid having a large viscosity, a large stirring blade 33 having an inclination is used, and when the viscosity is small, a small stirring blade 33 having no inclination is used.

反応液の粘性が大きい場合には、反応室内の流れが層状（層流）となり撹拌され難い可能性があるので、大きな撹拌羽33に傾斜をもたせる方が良い。逆に、粘性の小さい反応液の場合には、傾斜の小さい撹拌羽33でも撹拌できる。   If the viscosity of the reaction solution is large, the flow in the reaction chamber may become laminar (laminar flow) and may not be easily stirred, so it is better to have the large stirring blade 33 inclined. On the contrary, in the case of a reaction liquid having a low viscosity, the stirring blade 33 having a small inclination can be stirred.

図８および図９に示す構成は、ともに、第１および第２円板31、32の下面にも採用することができる。図８および図９に示す撹拌羽は３個であるが、これに限定せず、複数個設けて良い。   Both the configurations shown in FIGS. 8 and 9 can also be employed on the lower surfaces of the first and second disks 31 and 32. Although the number of stirring blades shown in FIGS. 8 and 9 is three, the present invention is not limited to this, and a plurality of stirring blades may be provided.

さらに、図１０〜図１２に示す構造を、第２円板32の外周縁部に採用することが好ましい。   Furthermore, it is preferable to employ the structure shown in FIGS. 10 to 12 at the outer peripheral edge of the second disc 32.

図１０では、第２円板32の外周面に環状溝41が形成されている。溝41を設けると、流れに渦を発生させることで流れの抵抗を大きくすることができる。溝41の幅ｂは、第２円板32の厚さｔに対して３分の１程度で、深さｄは幅ｂと同程度とする。溝41の幅ｂおよび深ｄさが小さすぎると、流れの抵抗となるような渦が発生しない。   In FIG. 10, an annular groove 41 is formed on the outer peripheral surface of the second disc 32. When the groove 41 is provided, the flow resistance can be increased by generating a vortex in the flow. The width b of the groove 41 is about one third of the thickness t of the second disk 32, and the depth d is about the same as the width b. If the width b and depth d of the groove 41 are too small, vortices that cause flow resistance are not generated.

図１１では、第２円板32の外周縁下面に複数のと突起42が一定間隔で設けられている。突起42を設けると、流れの抵抗を大きくすることができる。突起42の形状は、流れを遮る三角形が望ましい。突起41の高さｈは、第２円板32の厚さｔの半分程度が望ましい。   In FIG. 11, a plurality of protrusions 42 are provided at regular intervals on the lower surface of the outer peripheral edge of the second disc 32. Providing the protrusions 42 can increase the flow resistance. The shape of the protrusion 42 is preferably a triangle that blocks the flow. The height h of the protrusion 41 is preferably about half of the thickness t of the second disk 32.

図１２では、第２円板32の外周面に面粗さ部43が形成されている。面粗さ部43の形成は、第２円板32の外周面に細かい傷を無数につけるように加工することによる。   In FIG. 12, a surface roughness portion 43 is formed on the outer peripheral surface of the second disc 32. The surface roughness portion 43 is formed by processing the outer peripheral surface of the second disc 32 so as to make countless fine scratches.

上記において、連続式の反応容器では、反応に必要な滞留時間が得られるように、反応容器と時間当たりの流入量によって決定される。   In the above, in a continuous reaction vessel, it is determined by the reaction vessel and the amount of inflow per hour so as to obtain a residence time necessary for the reaction.

反応室の容積をＸ（ｍ３）、反応室の数をｎ、反応容器への流入量をＹ（ｍ３／ｓ）とすると、反応容器内の平均滞留時間は、ｎＸ／Ｙ（ｓ）となる。 Assuming that the volume of the reaction chamber is X (m 3 ), the number of reaction chambers is n, and the flow rate into the reaction vessel is Y (m 3 / s), the average residence time in the reaction vessel is nX / Y (s) It becomes.

反応容器内の平均滞留時間は、ｎＸ／Ｙ（ｓ）をどれくらいにするかについては、投入する化学物質を反応させて生成物の濃度が高い溶液を得るために、化学反応によって反応する物質の特性によって決めている。   Regarding the average residence time in the reaction vessel, how much nX / Y (s) should be set, in order to obtain a solution having a high product concentration by reacting the chemical substance to be added, It depends on the characteristics.

このようにすることで、
(1)反応がより進行した状態の溶液（生成物の濃度が高い溶液）を得られる、
(2)同濃度の生成物を同量得るために必要な反応容器の容積が小さくて済む、
(3)同濃度の生成物を得るための反応時間を短縮できる（時間当たりの処理能力が増加する）、ということになる。 By doing this,
(1) A solution with a more advanced reaction (solution with a high product concentration) can be obtained.
(2) The volume of the reaction vessel required to obtain the same amount of product of the same concentration is small,
(3) The reaction time for obtaining a product with the same concentration can be shortened (the throughput per hour increases).

反応容器をいくつの反応室に区分するかについては、投入する化学物質を反応させて生成物の濃度が高い溶液を得るために、化学反応によって反応する物質の特性によって反応室の数を決めている。   Regarding how many reaction chambers are divided, the number of reaction chambers is determined according to the characteristics of the substances that are reacted by the chemical reaction in order to obtain a solution with a high product concentration by reacting the input chemical substances. Yes.

化学反応によって反応する物質の特性によって反応室の数を決めた後、以下のように同流入量で反応室の数を変更すると好ましくない。   After determining the number of reaction chambers according to the characteristics of the substance that reacts by chemical reaction, it is not preferable to change the number of reaction chambers with the same inflow amount as follows.

区画室を増やした場合、１つの反応室での滞留時間が短くなり、反応物質同士の遭遇回数が少なくなり、反応物の溶液を高い状態にもっていかなくなる。また、装置自体の製造コスト増にもつながる。   When the number of compartments is increased, the residence time in one reaction chamber is shortened, the number of encounters between the reactants is reduced, and the solution of the reactants cannot be brought into a high state. It also leads to an increase in the manufacturing cost of the device itself.

また、区画を減らした場合、１つの反応室での滞留時間が長くなり、反応済みの溶液と１つ前の溶液と混合されてしまい、反応物の溶液を高い状態のまま保つことが出来なくなる。   In addition, when the number of compartments is reduced, the residence time in one reaction chamber becomes longer, and the reacted solution and the previous solution are mixed, so that the solution of the reactant cannot be kept high. .
