Description

この発明は、マイクロ化学プロセスに必要な高効率な混合機能を達成するために流体の衝突または流れ変化による乱流効果を利用する衝突型ミキサーに関し、特には、例えば欧州ではμ−TAS(Micro Total Analysis Systemの略)、米国ではLab−on−A−Chipと称されるマイクロリアクターに代表される微細構造をもつマイクロ流体素子に用いて好適な、微量流体の混合・撹拌を行なう衝突型マイクロミキサーに関するものである。   The present invention relates to a collision type mixer that utilizes the turbulent flow effect caused by the collision or flow change of a fluid in order to achieve a highly efficient mixing function required for a microchemical process. In particular, in Europe, for example, μ-TAS (Micro Total (Abbreviation of Analysis System), a collision type micromixer that mixes and agitates a small amount of fluid, which is suitable for microfluidic devices having a microstructure represented by a microreactor called Lab-on-A-Chip in the US It is about.

マイクロ化学プロセス用デバイスに必要とされる重要な機能として「混合」があるが、有効な混合装置(ミキサー)の提案は未だ少ない。公知のマイクロ化学プロセス用の衝突型混合装置としては、交互流れによる方法や機械的な撹拌等の方法の提案があるが(特許文献1参照)、何れも装置が大掛かりになったり構造が複雑になったりするため、その大きさや価格がマイクロ化学プロセスには適していないとされている。   “Mixing” is an important function required for devices for microchemical processes, but there are still few proposals for effective mixing devices (mixers). As a collision type mixing apparatus for a known microchemical process, there are proposals of an alternating flow method and a mechanical stirring method (see Patent Document 1). Therefore, the size and price are not suitable for microchemical processes.

この問題を解決するために簡易的で一般的な方法として、例えば図39(a)に示すチューブで連結されたT字管(T字路)や図39(b)に示すY字管(Y字路)内での流体の衝突乱流を利用する方法や、図40(a),(b)に正面図および断面図を示す吐出噴出流による衝突乱流を利用する方法が提案されている。
特開2006−320877号公報
In order to solve this problem, as a simple and general method, for example, a T-shaped tube (T-junction) connected by a tube illustrated in FIG. 39A or a Y-shaped tube (Y There have been proposed a method using a collision turbulent flow of a fluid in a path and a method using a collision turbulent flow due to a discharge jet flow shown in front and sectional views in FIGS. 40 (a) and 40 (b). .
JP 2006-320877 A

しかしながら、これら管やチューブを連結した方法や噴出流衝突方法では、流路の姿勢、位置関係、長さ等の寸法的条件の他、対象流体の流れ特性の変化等、流れ状態を正確に設定することの困難を伴い、乱流状態の確実性や継続性を維持することは非常に難しく、流れ特性の不安定を招き、混合特性にばらつきを生ずることがある。   However, with these pipe and tube connection methods and jet flow collision methods, the flow conditions such as changes in the flow characteristics of the target fluid, as well as dimensional conditions such as the posture, positional relationship, and length of the flow path are accurately set. It is very difficult to maintain the certainty and continuity of the turbulent flow state, which may cause instability of the flow characteristics and cause variations in the mixing characteristics.

また、上記の管やチューブの組み合わせの場合、不要部やジョイント部を必要とするためどうしても装置が大型化してしまい、しかも上記の管やチューブを連結した方法や噴出流衝突方法は、機械的撹拌方法や交互流れ法と同様、どうしてもマイクロリアクターに外付けする構造となるため、マイクロリアクターの特徴の一つである小型化、集積化を困難にし、そのマイクロリアクターが実用化された場合には、同種のマイクロリアクターを複数並列に並べて生産量を確保するナンバリングアップが非常に困難な状況が予想される。   Also, if the combination of the above tube or tubes, increased in size inevitably device requires a unnecessary portion or joint portion, moreover a method and jet flow collisions method connecting the tube or tubes, mechanical stirrer Like the method and the alternating flow method, the structure is inevitably externally attached to the microreactor, making it difficult to downsize and integrate one of the features of the microreactor. When the microreactor is put into practical use, It is expected that it will be very difficult to increase the numbering by arranging multiple microreactors of the same type in parallel to secure the production volume.

それゆえこの発明は、マイクロチャンネル内部で混合対象の複数流体の衝突または流れ方向や速度の変化による乱流を発生させて混合機能に利用し、マイクロリアクターの小型化、集積化を可能にするために、その乱流を意図的にかつ確実に発生させるための構造を提案することを目的としている。   Therefore, the present invention generates a turbulent flow due to collision of a plurality of fluids to be mixed in the microchannel or changes in flow direction and speed, and uses it for the mixing function to enable miniaturization and integration of the microreactor. Another object is to propose a structure for intentionally and reliably generating the turbulent flow.

この発明は、上記課題を有利に解決するものであり、この発明の衝突型マイクロミキサーは、数十μm〜数mmの幅や深さの微小チャンネル(微小溝)もしくは微小スリットで構成される微小流路の内部を流れる液体に乱流を確実に発生させて高効率の混合を得るために、流路の交差角度の効果、流路の交差方向の効果、合流ユニットの多種または同種の多段の組み合わせの効果、合流ユニットの流路長さの非対称の効果、合流ユニットの流路断面積の非対称の効果、合流ユニットの流路変曲部(折れ線状、曲線状等)の形状の効果、合流ユニットの途中の流路断面積の変化の効果、そして合流ユニットの途中の流路内遮蔽物の効果を、独立で、または組み合わせて用いたものである。   The present invention advantageously solves the above problems, and the collision type micromixer according to the present invention is a microchannel (microgroove) or microslit having a width and depth of several tens of μm to several mm. In order to reliably generate turbulence in the liquid flowing inside the flow path and to obtain highly efficient mixing, the effect of the crossing angle of the flow path, the effect of the crossing direction of the flow path, various types of merging units or multiple stages of the same type Effect of combination, effect of asymmetry of flow path length of merging unit, effect of asymmetry of flow path cross-sectional area of merging unit, effect of shape of flow path inflection part (broken line, curved shape, etc.) of merging unit, merging The effect of the change in the cross-sectional area of the channel in the middle of the unit and the effect of the shielding in the channel in the middle of the merging unit are used independently or in combination.

すなわち、この発明の衝突型マイクロミキサーは、二つの部材間に挟まれたプレートに形成されたスリットまたは、部材もしくはプレートの表面に形成されて他の部材で蓋をされた溝によりそれぞれ構成された第1の流入流路と第2の流入流路と流出流路とを具え、前記第1の流入流路と前記第2の流入流路とは互いに対向もしくは交差する方向に延在してそれらの衝突点または交差点で合流し、前記流出流路は前記第1の流入流路と前記第2の流入流路とが合流した点から前記第1の流入流路および前記第2の流入流路の両方と交差するかまたは、前記第1の流入流路と前記第2の流入流路とが互いに対向する方向に延在している場合以外にそれらの何れか一方の延長方向に延在していることを特徴としている。   That is, the collision type micromixer of the present invention is configured by a slit formed in a plate sandwiched between two members or a groove formed on the surface of the member or the plate and covered with another member. A first inflow channel, a second inflow channel, and an outflow channel, wherein the first inflow channel and the second inflow channel extend in a direction facing or crossing each other; The first inflow channel and the second inflow channel from the point where the first inflow channel and the second inflow channel merge. Or the first inflow channel and the second inflow channel extend in any one of the extending directions other than the case where the first inflow channel and the second inflow channel extend in a direction facing each other. It is characterized by having.

かかる構成により、プレートが充分に薄い場合はスリットが微小流路を形成し、部材もしくはプレートの表面に形成された溝もその深さや幅が充分に小さい場合は数十μm〜数mmの幅や深さの微小流路を形成するので、それらのスリットや溝で形成された第1の流入流路と第2の流入流路とが互いに対向もしくは交差する方向に延在していることで、第1の流入流路と第2の流入流路とをそれぞれ流れてきた流体がそれらの流路の合流点で真正面から、または角度を持って衝突して乱流が発生し、第1の流入流路と第2の流入流路とをそれぞれ流れてきた流体が混合された流体が流出流路から流出する。   With this configuration, when the plate is sufficiently thin, the slit forms a minute flow path, and when the depth or width of the groove formed on the surface of the member or the plate is sufficiently small, the width is several tens of μm to several mm. Since a minute flow channel with a depth is formed, the first inflow channel and the second inflow channel formed by the slits and grooves extend in a direction facing or intersecting each other, The fluid flowing through the first inflow channel and the second inflow channel collide from the front or at an angle at the merging point of the channels to generate a turbulent flow. The fluid mixed with the fluid flowing through the flow path and the second inflow path flows out from the outflow path.

従ってこの発明の衝突型マイクロミキサーによれば、プレートあるいは部材表面を利用してマイクロミキサーを構成できるので、マイクロリアクターの小型化、集積化を可能にすることができる。   Therefore, according to the collision type micromixer of the present invention, since the micromixer can be configured using the plate or the surface of the member, the microreactor can be miniaturized and integrated.

以下、この発明の実施の形態を図面に基づき詳細に説明する。ここに、図1〜図10は、この発明の衝突型マイクロミキサーの各種実施形態を図示するものであり、図中符号1は第1の流入流路、2は第2の流入流路、3は流出流路、そして4はそれらを組み合わせた合流ユニット、Iは合流点、Dは分岐点をそれぞれ示す。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 10 show various embodiments of the collision type micromixer according to the present invention.
