口１０を形成してある。Configuration of a conventional example and its problems A conventional material separation device using an impregnated liquid membrane will be explained based on FIGS. 1 and 2. This conventional example has the same structure in principle as a shell-and-tube heat exchanger, in which 1 is a porous pipe impregnated with a liquid membrane component, and both ends are connected to tube plates 2 and 3.
is supported by Reference numeral 4 denotes a shell that fits onto the pipe 1 and has both ends fixed to the respective tube plates 2 and 3, and has an extraction liquid inlet 5 and an extraction liquid outlet 6.
7 and 8 are end plates that are fitted onto the respective tube sheets 2 and 3,
An extracted liquid inlet 9 is formed on one side, and a raffinate liquid outlet 10 is formed on the other side.

６から排出される。 In the above configuration, the liquid to be extracted is transferred to the liquid to be extracted at the liquid inlet 9
When injected into one end plate 7, the liquid to be extracted passes through each pipe 1, and while passing through the pipes 1, the carrier of the liquid film impregnated in the pipe 1 absorbs specific components of the liquid to be extracted. It is carried to the outside of the pipe 1 and delivered to the extraction liquid injected into the shell 4 from the extraction liquid inlet 5. The raffinate is then discharged from the raffinate outlet 10, and the extract containing the above-mentioned specific components is discharged from the extract outlet 6.

間隙があり、能力の割りには大型である。 According to the above configuration, since the liquid film is supported only on the pipe 1, deterioration of the membrane function over time due to elution of the liquid film components is inevitable.
The pipe 1 needs to be replaced when it has deteriorated beyond a certain limit. In addition, there is a relatively large gap between the pipes, and the pipe is large considering its capacity.
