Description

  The present invention relates to a flow observation container for injecting a solution, which is an observation sample, into a container and allowing the light to pass through the circulation sample and observing the distribution state while circulating the solution.

Observing the flow of fluid and the mixing of two fluids is an extremely important factor when building a new process. And in order to observe this, it is indispensable to visualize the flow path. (For example, see the microscopic observation container described in Patent Document 1) However, in the case of high-temperature and high-pressure conditions, it was very difficult to produce a transparent flow tube due to strength problems.
Japanese Patent Application No. 2002-31580

  Conventionally, the inventor can make a visual observation at high temperature and high pressure by hollowing out a cylindrical sapphire container to form a distribution pipe and sandwiching the upper and lower portions thereof with a TTS seal mechanism or the like that minimizes distortion. A distribution observation vessel was provided.

Furthermore, as a general high-temperature high-pressure fluid observation container, as shown in FIG. 11 , a sample chamber A, a window support B, a seal C, a window plate D, and a window holding metal E that are constituted by a part of the main body. There is something that consists of.

  In the case of a flow observation container formed by hollowing out the cylindrical sapphire container, a large and expensive cylindrical sapphire container needs to be used. In addition, the two-component mixing of the sample solution is only from the linear direction, and it is unavoidable that there is a limitation in use that cannot be used for general-purpose T-shaped mixing.

Furthermore, in the case of the conventional container shown in FIG. 11 , since a space a is formed between the sample chamber A and the window D, even though the sample staying in the sample chamber A can be observed, Accurate observation of the flow state of the flowing sample has been impossible based on the existence of the space a, for example, based on vortex generation.
The present invention is intended to provide a new flow observing vessel that solves the above problems.
