Description

[Detailed description of the invention] The present invention relates to a liquid retention tank that is equipped with multiple rectifier plates having a large number of liquid passage holes.In particular, a mixed solution containing multiple components is passed through an adsorption tower, and the concentration of the multiple components is When a liquid that flows out with a chromatographic concentration distribution is repeatedly passed through an adsorption tower in the order in which it flows out to separate multiple components, the liquid that flows out of the adsorption tower with a chromatographic concentration distribution of such a multi-component The present invention relates to a liquid retention tank for liquid. The present invention allows liquids flowing into a liquid retention tank with varying concentrations of multiple components to be retained in the order in which they flow and while preventing mixing of liquids with different components or concentrations due to liquid agitation and convection, and to retain the liquids. The purpose is to cause the multiple components that have flowed into the tank to flow out of the tank in the order of their concentration distribution.

In a conventional liquid retention tank, horizontal partition plates are installed in multiple stages in the tank to partition the tank into a plurality of retention chambers. In the liquid retention tank, in which openings for allowing the liquid to flow down are provided at alternately opposing end positions of the lower partition plates thereafter, an opening rectifier plate having a plurality of liquid passage ports is provided in the openings. Further, a retention chamber rectifying plate having a plurality of liquid passage ports is provided at any location of the retention chamber partitioned by each partition plate.

In such a liquid retention tank, the liquid is allowed to accumulate in the tank from the lower retention chamber in the order in which it flows into the tank, and each partition plate prevents stirring of the liquid in the entire liquid retention tank and mixing by convection. At the same time, it is possible to prevent the liquid stagnant in the tank from drifting and let it flow out from below in the order of the components and concentrations that have flowed in. However, the structure is complex, making it expensive to manufacture, and the capacity is relatively small. It was difficult to manufacture.

The present invention is characterized by simplifying the structure without sacrificing the advantages of conventional liquid retention tanks, making it possible to reduce manufacturing costs, and making it easy to manufacture even for relatively small volumes. It is something.

The present invention will be explained with reference to a diagram showing an example of an embodiment. 1 is a liquid retention tank, and a horizontal rectifying plate 2 provided with a large number of liquid passage holes 8 is installed in the liquid retention tank 1 in an appropriate manner. They are provided in multiple stages at intervals and partitioned into a plurality of retention chambers 7a to 7e. As the liquid passage hole 8, for example, a large number of holes or slits are provided, but the liquid passage hole may have any shape other than holes or slits as long as it has a liquid rectifying effect. Further, it is appropriate that the area of the liquid passage holes 8 be approximately 5 to 20% of the total area of the current plate 2.

The number of rectifier plates 2 and the plate spacing depend on the properties of the liquid flowing through it,
It is determined as appropriate depending on the amount of liquid passed, the flow rate of liquid passed, etc., but usually 3 to 10 sheets are preferable, and the interval is suitably 20 to 120 cm. Also, a plurality of rectifier plates 2a to 2d
An air vent pipe 3 is attached through the air vent pipe 3, and an air vent hole 9 is provided below the joint portion of the air vent pipe 3 with each rectifying plate.

4 is a liquid inflow pipe, and 5 is a liquid outflow pipe having a valve 6.

The operation of the liquid retention tank of the present invention will be explained.
First, the valve 6 of the outflow pipe 5 is closed, and the liquid flowing out with a chromatographic concentration distribution of multiple components is transferred to the inflow pipe 5.
When the liquid flows into the liquid retention tank 1 from
a, 2b, 2c, and 2d in order, and
The lower retention chamber 7
Retention chambers 7d, 7c, 7b, gradually above e.
7a will be fulfilled.

At this time, the air in the tank 1 is discharged from the air vent hole 9 through the air vent pipe 3 to the outside of the tank 1 instead of replacing the inflowing liquid, so that the liquid can easily flow into each retention chamber 7. .

By partitioning the liquid retention tank 1 into retention chambers 7 with a rectifying plate 2, liquids with different components and concentrations flowing into each retention chamber 7 can be stirred by the liquid flow and the liquid between the retention chambers 7 can be mixed by convection. Liquid can be retained while preventing mixing.

It is difficult to prevent liquid mixing due to diffusion in a simple conventional liquid retention tank without a current plate 2 or partition plate as in the present invention, but in the present invention, a current plate with a large number of liquid passage holes is used. By appropriately setting the interval between the two, it is possible to minimize the mixing ratio due to liquid diffusion.

After filling the liquid retention tank 1 with a predetermined amount of liquid, the inflow of liquid from the inflow pipe 4 is stopped, and then the valve 6 of the outflow pipe 5 is opened to allow the liquid in the liquid retention tank 1 to flow out from the outflow pipe 5. However, at this time, by rectifying the flowing liquid by the rectifying plate 2 having a large number of liquid passage holes 8, uneven flow of the liquid in the retention chamber 1 is prevented, and the retention below from the outflow pipe 5 is prevented. The liquid staying in the chamber 7e can be made to flow out of the tank 1 sequentially, that is, in the order of the concentration distribution of the multiple components that have flowed into the liquid storage tank 1. Also, the flow rate of the liquid at this time is LV0.2~2cm/
It is preferable to set it to sec.

In this manner, the liquid retention tank of the present invention allows liquid flowing into the tank with a chromatographic concentration distribution of multiple components to be controlled by the rectifying action of the current plate having a large number of holes or slits. It is possible to easily accumulate liquids one after another from the lower retention chamber partitioned by a rectifying plate without mixing liquids with different components and concentrations in the order in which they flow in, and to prevent drifting of the accumulated liquid while preventing liquids from flowing in. It can be discharged in order of concentration.

In addition, the liquid retention tank according to the present invention is used, for example, in an ion exchange device, in which the regenerated liquid discharged during the regeneration process flows in the order in which it flows out, and is stored while preventing the liquid from dispersing in the retention chamber, and in the order in which it flows in from below. It can also be used for draining.
