Description

Technical Field

[0001] The utility model relates to the field of chemical engineering, in particular to a gas separation and purification device. Background Art

[0002] Currently, gas separation and purification methods mainly include chemical absorption, physical adsorption, freezing, membrane separation technology, etc. For example, chemical absorption achieves separation through the reaction of specific chemical reagents with target impurities, but this method is often accompanied by high chemical reagent consumption, high operating costs and possible secondary pollution problems. Physical adsorption technology uses the difference in adsorption properties of porous materials for different gas molecules to separate gases. However, the selectivity of the adsorbent is limited and the regeneration process is complicated. The freezing method condenses certain components by cooling and then separates them, but it has high energy consumption and strict temperature control requirements. Although membrane separation technology has the advantages of low energy consumption and simple operation, its removal efficiency for certain trace impurities is not ideal.

[0003] Existing technologies often struggle to efficiently and quickly remove argon gas containing electrically charged impurities, such as metal ions. Metal ions not only affect the purity of the final argon gas product but can also cause corrosion damage to equipment in subsequent processes, reducing overall system stability and lifespan.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The gas separation and purification device according to an embodiment of the present invention will be described below with reference to the accompanying drawings. It should be noted that the gas separation and purification device according to an embodiment of the present invention is mainly used for separation and purification of argon gas.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, a gas separation and purification device includes: an air pump 1, a separation and purification tank 2, two electrode sheets 3, an activated carbon filter tank 4, a first liquid pump 5, a first storage tank 6, a second liquid pump 7, a second storage tank 8, a heat exchanger 9 and a compressor 10, wherein:

[0030] The discharge port of the air pump 1 and the feed port of the separation and purification tank 2 are connected through a conduit. The separation and purification tank 2 is cylindrical, and two electrode sheets 3 are arranged on the outer wall of the separation and purification tank 2. When the two electrode sheets 3 are connected to the power supply, the two electrode sheets 3 form a magnetic field inside the separation and purification tank 2.

[0031] The activated carbon filter tank 4 is arranged on the conduit between the air pump 1 and the separation and purification tank 2. The discharge port of the air pump 1 and the feed port of the activated carbon filter tank 4 are connected through the conduit, and the discharge port of the activated carbon filter tank 4 and the feed port of the separation and purification tank 2 are connected through the conduit.

[0032] The feed port of the first liquid pump 5 is communicated with the first storage tank 6 through a conduit, and the discharge port of the first liquid pump 5 is communicated with the conduit between the activated carbon filter tank 4 and the separation and purification tank 2 through a conduit.

[0033] The discharge port of the second liquid pump 7 is connected to the second storage tank 8 through a conduit, and the feed port of the second liquid pump 7 is connected to the discharge port of the separation and purification tank 2 through a conduit and a three-way pipe.

[0034] The first storage tank 6 and the second storage tank 8 are communicated with each other through a conduit.

[0035] The heat exchanger 9 and the compressor 10 are respectively arranged on the conduit between the first storage tank 6 and the second storage tank 8. The feed port of the heat exchanger 9 is connected to the second storage tank 8 through the conduit, the discharge port of the heat exchanger 9 is connected to the feed port of the compressor 10 through the conduit, and the discharge port of the compressor 10 is connected to the first storage tank 6 through the conduit.

[0036] The conduit provided at the discharge port of the activated carbon filter tank 4 and the conduit provided at the discharge port of the separation and purification tank 2 are respectively provided with valves 11 .

[0037] The air pump 1, the separation and purification tank 2, the activated carbon filter tank 4, the first liquid pump 5, the first storage tank 6, the second liquid pump 7, the second storage tank 8, the heat exchanger 9 and the compressor 10 are arranged on a skid-mounted platform.

[0038] The first storage tank 6 and the second storage tank 8 are respectively used to store methanol.

[0039] Specifically, the relevant staff connected the power supply to the two electrode sheets 3, and the two electrode sheets 3 formed a magnetic field inside the separation and purification tank 2;

[0040] Subsequently, the relevant staff started the gas separation and purification device. The air pump 1 first introduced the argon mixed gas into the activated carbon filter tank 2. The activated carbon filter tank 2 would first filter out the metal particles with larger diameters in the argon mixed gas. The filtered argon mixed gas then entered the separation and purification tank 2. At this time, when the argon mixed gas passed through the separation and purification tank 2, the metal particles or metal ions in the argon mixed gas were adsorbed inside the separation and purification tank 2 under the action of the Lorentz force of the magnetic field between the two electrode sheets 3.

[0041] It should be noted that after the separation and purification tank 2 has been working for a long time, a large amount of metal particles and metal ions will be adsorbed on its inner wall. At this time, the interior of the separation and purification tank 2 needs to be cleaned.

[0042] When the inner wall of the separation and purification tank 2 needs to be cleaned, the two valves 11 are first closed, and then the first liquid pump 5 is started to introduce the methanol from the first storage tank 6 into the separation and purification tank 2 to dissolve and rinse the metal particles or metal ions on the inner wall of the separation and purification tank 2. Then, the methanol carrying the metal particles or metal ions is introduced into the second storage tank 8 under the drive of the second liquid pump 7;

[0043] At this time, in order to reuse the methanol, the second storage tank 8 collects the methanol into the heat exchanger 9 through the evaporator. When the methanol in the second storage tank 8 evaporates, the metal particles or metal ions dissolved in it remain in the second storage tank 8.

[0044] The methanol is cooled and liquefied by the heat exchanger 9 and the compressor 10 and then flushed into the first storage tank 6 for next use.

[0045] In summary, the gas separation and purification device according to the embodiment of the present invention can efficiently remove metal ions in the gas passing through the separation and purification tank through the magnetic field generated by the two electrode sheets.
