[0050] figure 1 The shown reaction device of the present invention has a double tube structure composed of an outer cylinder member 52 and a core member 54 . in addition, figure 1 The shown device has a double tube structure, however, if necessary, further tubes may be provided on the outside of the outer cylinder member 52 to have a triple tube structure. exist figure 1 In the illustrated embodiment, the outer cylinder member 52 is formed by perforating polygonal columns to form an inner cavity through which fluid can flow, but the present invention is not limited thereto. For example, a straight pipe may be used, or a flat plate may be excavated to form a groove, and a cover may be placed there to form a cavity through which a fluid can flow. In addition, in figur...

In addition, in the present invention, the so-called substantially orthogonal or substantially right angle is 90°±45°. When the connection is made in a direction substantially perpendicular to the peripheral surface, the supplied fluid collides with the core member and spreads to the left and right of the annular reaction channel, resulting in complicated convection.

Abstract

Disclosed is a pipe type circulation-based reaction apparatus which comprises two or more fluid supply passages formed by a multi-layered tube for supplying two or more types of fluids to be used for reaction; a reaction flow passage which has an annular cross section and is capable of reacting said fluids while causing the same to circulate; and a fluid discharge passage for discharging resection products. In order that the fluid supply passages may communicate with the inlet to the reaction flow passage, the fluid supply passages are connected along a circumferential tangent direction of the annular reaction flow passage or along a direction intersecting the circumferential surface thereof at right angles. Furthermore, the fluid discharge passage is connected to the outlet of the reaction flow passage in such a way as to establish communication.

Description

technical field [0001] The invention relates to a tubular flow-through reaction device. More specifically, the present invention relates to a tube-type flow-through reactor that increases the contact area between reaction substrates immediately after merging and suppresses a reduction in the production rate of reaction products due to concentration variations. Background technique [0002] In recent years, as flow-through reactors for reacting liquids such as reagents, micro-sized and millimeter-sized reactors, for example, have been developed. [0003] As the simplest form of the microreactor, a T-type or Y-type reactor can be cited. In this reactor, T-shaped or Y-shaped grooves with a depth of 40 μm and a width of 100 μm were engraved on a plate, and a cover was made of a flat plate and connected to a tube. One is opened at the end of each T or Y on the plate to be the cover, for a total of three holes. Two kinds of reaction substrates are put into the left and right si...
