Description

Technical Field

[0001] This utility model relates to the field of wet electronic chemical purification, and in particular to a liquid purification device. Background Technology

[0002] Laboratory purification processes often use ion exchange resins to purify feed solutions (such as ethanol, acetone, etc.). The solution is added manually, and collected by controlling the opening of a bottom valve. Figure 2 This experimental setup requires staff to spend a long time observing the remaining liquid level. There is a potential risk of contamination and splashing of the liquid during the addition process. It also makes the experimental parameters less reliable and difficult to generate reliable experimental data for theoretical analysis. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 One embodiment of this utility model is a liquid purification device, comprising: a storage tank 1; the output end of the storage tank 1 is connected to a pump body 2; and the output end of the pump body 2 is connected to at least one or more reaction columns.

[0025] In this embodiment, the liquid to be purified is placed inside the storage tank 1, and the reaction column is filled with resin particles inside. The storage tank 1 is designed to be connected to two sets of reaction columns in sequence to increase the contact time between the liquid and the resin and improve the purification effect. The pressure inside the device is adjusted by adjusting the flow rate of the pump body 2, which facilitates experimental control.

[0026] There are two reaction columns connected in series.

[0027] In this embodiment, the reaction columns are connected in sequence so that the feed liquid can fully contact the resin for ion exchange.

[0028] The liquid storage tank 1 is an integrated tank body, and an air inlet 11 and an air outlet 12 are provided on the top of the liquid storage tank 1.

[0029] In this embodiment, nitrogen gas is introduced into the inside of the storage tank 1 through the air inlet 11 and the air outlet 12 for nitrogen sealing to prevent the liquid from being contaminated.

[0030] An output end is provided at the bottom of the liquid storage tank 1, which is connected to the pump body 2.

[0031] In this embodiment, the pump body 2 is a peristaltic pump, which can slowly transport the liquid in the storage tank 1 in batches.

[0032] A pressure gauge 5 is installed between the pump body 2 and the input end above the first reaction column 3.

[0033] In this embodiment, the pressure at the input end of the first reaction column 3 is detected by the pressure gauge to prevent some resin particles from clogging the first reaction column 3, causing excessive pressure in the pipeline and increasing the experimental risk.

[0034] The input end of the first reaction column 3 is equipped with a first valve body 6, which is connected to the outside.

[0035] In this embodiment, the first valve body 6 is an exhaust valve. When conveying the liquid, the gas in the first reaction column 3 and pipeline is discharged through the first valve body 6. After the exhaust is completed, the first valve body 6 is closed to continue conveying the liquid.

[0036] A second valve body 7 is installed at the output end below the first reaction column 3.

[0037] In this embodiment, the second valve body 7 is a flow valve, which can be used to sample the purified liquid or to depressurize it.

[0038] The second valve body 7 is connected to the input end of the second reaction column 4.

[0039] In this embodiment, the second valve body 7 is a three-way valve, which can also be connected to the second reaction column 4 to transport the liquid to the second reaction column 4 for further purification and extend the reaction time.

[0040] The input end of the second valve body 7 is provided with a third valve body 8, which is connected to the outside.

[0041] In this embodiment, the third valve body 8 is the same as the first valve body 6, both being exhaust valves to discharge the gas in the second reaction column 4 and pipeline.

[0042] The output end of the second reaction column 4 is connected to the fourth valve body 9.

[0043] In this embodiment, the fourth valve body 9 is the same as the second valve body 7, and it is used to depressurize or sample the liquid.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
