Description

  The present invention relates to a reaction apparatus and a reaction plant in which a liquid or a gas is mixed and reacted in a channel in fields such as chemical synthesis and chemical analysis.

In recent years, in the field of chemical synthesis and chemical analysis, a reactor manufactured by a micromachining technique called MEMS (Micro Electro Mechanical System) has begun to be used. The flow path of this reactor is formed with a cross-sectional dimension of several tens to several hundreds μm, and such a reactor is called a microreactor or a micromixer.

  In the microreactor, two or more kinds of fluids containing a substance to be reacted are prepared, and the reactants are generated by bringing them into contact with each other in a fine flow path by merging and causing a chemical reaction. In the microreactor, the width and height of the flow path are small, the surface area per volume of the reaction part is large, and the volume of the flow path is small. Therefore, heat exchange is good and the mixing time of the substance is short, so that by-products due to the reaction are reduced and the reaction yield is increased.

  The amount of chemical substances produced by one such microreactor is about several mL per minute, and in the case of industrial mass production, it is considered to install a plurality of microreactors in parallel. A method of increasing the production volume by arranging a plurality of microreactors in parallel is called numbering up of the microreactors.

  In [Patent Document 1], in order to increase the numbering of microreactors, a plurality of branch pipes having a plurality of outlets with respect to one inlet are connected in multiple stages, and the outlets of the branch pipes are connected to a plurality of microreactors arranged in parallel. A microreactor system is described.

  [Patent Document 2] describes a microreactor device in which a plurality of microreactor units are arranged in parallel, and a two-way valve and a needle valve are respectively provided in a raw material supply pipe to adjust the pressure loss of the microreactor unit using the needle valve. Has been.

  Since the microreactor system described in [Patent Document 1] has a plurality of branch pipes connected in multiple stages, there is a problem that the branch pipes or the pipes connecting the branch pipes and the microreactor become complicated. In addition, the lengths of the pipes connecting the microreactors are often different, and there is a problem that a difference occurs in the generated reactants because an equal flow rate distribution is not performed. That is, when the target substance R is generated by mixing the fluid containing the substance A having the same concentration and the fluid containing the substance B, if the flow rate of the fluid containing the substance B is large, R + B → S (by-product Reaction) occurs, a large amount of by-product S is generated, and the yield of the target substance R decreases.

  Since the microreactor device described in [Patent Document 2] has a structure in which a needle valve is provided at each inlet of a plurality of microreactors to adjust the flow rate, it is necessary to adjust each needle valve, which makes the operation complicated. There is a problem of end. In addition, it is difficult to perform uniform flow distribution, and there is a similar problem that a large amount of by-product S is generated and the yield of the target substance R is reduced.

  An object of the present invention is to provide a reaction apparatus and a reaction plant that can uniformly distribute a flow rate to a plurality of numbered microreactors, and that can increase a production amount by a microreactor having a high reaction yield.

  In order to achieve the above object, the reactor of the present invention synergizes the effect of increasing the substance diffusion due to the stirring effect due to the swirling flow, thereby improving the mixing performance and increasing the throughput. In contrast to a cylindrical mixing channel for mixing a plurality of fluids, an inlet channel for allowing a plurality of fluids to flow into the mixing channel is offset from the central axis of the mixing channel, and the mixing channel Are arranged symmetrically.

  According to the present invention, fluid can be uniformly distributed to each of a plurality of numbered microreactors, and the production amount can be increased by a high-yield microreactor.

  As shown in FIGS. 1 to 3, the flow path portion of the reaction apparatus includes a hollow cylindrical buffer 7 (also referred to as a first buffer 7) disposed outside, and a cylinder disposed in the hollow portion of the buffer 7. The buffer 7 is connected to a buffer 6 having a shape (also referred to as a second buffer 6), four cylindrical mixing channels 1 arranged at equal intervals between the inside of the buffer 7 and the outside of the buffer 6. Four introduction flow paths 23 (also referred to as first introduction flow paths 23) arranged in the vertical direction are connected to the sealed end portions of the introduction flow path 23 and the mixing flow path 1 and arranged in the horizontal direction.

  Here, in FIGS. 1 to 3, an example in which the buffer 6 has a cylindrical shape and the buffer 7 has a hollow cylindrical shape is shown. However, fluid can be introduced into the inlet channel 2 and the inlet channel 3 at a uniform flow rate. If it is a shape, it will not specifically limit.

  The buffer 6 and the buffer 7 are spaces for temporarily storing fluid, and are connected to the introduction flow path 22 and the introduction flow path 23, respectively. The introduction flow path 22 and the introduction flow path 23 are cylindrical. The inlet channel 2 and the inlet channel 3 are formed in a rectangular shape, and the fluid 4 containing the substance A (also referred to as a first substance) is guided to the mixing channel 1 by the introduction channel 22 and the inlet channel 2 to introduce the introduction flow.

  Since the swirl generation flow path 8 has poor fluid mixing properties, it is preferable that the swirl generation flow path 8 be short in order to suppress side reactions. In the present embodiment, the mixing flow path 1 and the swirl generation flow path 8 intersect at 90 degrees, but in order to shorten the length of the swirl generation flow path 8, the mixing flow path 1 and the swirl generation flow path 8 form. The angle may be 90 degrees or more and less than 180 degrees.

  In the present embodiment, four inlet channels 2 and four inlet channels 3 are installed, but one or more each may be installed. At that time, it is preferable to install the inlet channel 2 and the inlet channel 3 so as to be rotated with respect to the central axis of the swirl generation channel 8 so that the flow is uniform.

  According to the present embodiment, it is possible to improve the mixing property of a plurality of fluids, and therefore, it is possible to provide a mixing channel with high yield and high productivity by suppressing side reactions.
