Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to an electronic-grade xenon purification device. Background Art

[0002] Xenon, chemical symbol Xe, is a rare gas, an element in Group 18 of the periodic table, with atomic number 54. It is colorless, odorless, tasteless, and chemically inactive. It is present in air (0.0087 mL of xenon per 100 mL of air) and in the gases of hot springs. It is separated from liquid air along with krypton. Xenon has extremely high luminous intensity and is used in lighting technology to charge phototubes, flash lamps, and xenon high-pressure lamps. In addition, xenon is used as a deep anesthetic, medical ultraviolet light, lasers, welding, refractory metal cutting, calibration gases, and specialty gas mixtures. Xenon has a wide range of applications.

[0003] During the production process, xenon gas needs to be purified by a purification device to remove impurities contained in the xenon gas. Xenon gas purification cabinets are currently widely used xenon gas purification devices. During use, existing xenon gas purification cabinets pass crude xenon gas with impurities through a distillation tower for distillation and purification, and then fill it. However, existing xenon gas purification devices are not convenient for replacing the filling material that plays a filtering role in the purifier. In addition, it is not convenient to add the purifying agent placed on the shelf. At the same time, the heat dissipation performance of the purification cabinet is poor, and the heat generated during the purification process cannot be discharged from the cabinet in a timely and effective manner. To this end, we propose an electronic-grade xenon gas purification device. Utility Model Content

[0024] Specifically, by rotating the nut 9 to disengage it from the bolt 8, and then rotating the bolt 8 to disengage it from the flange 1 6 and the flange 2 7, the semicircular connector 1 3, the outer tank 4 and the semicircular connector 2 5 are separated, and the filter cotton filled inside can be replaced. On this basis, the slide 11 is pulled to one side to disengage it from the slide groove 10 on the outer tank 4, so that the upper inner tank 12 and the lower inner tank 13 are separated from the outer tank 4. Subsequently, because the slide 11 is no longer limited by the slide groove 10, the upper inner tank 12 and the lower inner tank 13 can be opened, so that the purification agent inside them can be operated.

[0025] In the first embodiment, a connection box 16 is fixedly connected to the middle portion of the rear side of the cabinet 1, a fan 17 is fixedly connected to the interior of the connection box 16, a cavity 18 is defined within the cabinet 1, the cavity 18 is communicated with the connection box 16, a plurality of circulation holes 19 are defined around the interior of the cabinet 1, and a plurality of heat dissipation holes 24 are defined on the left and right sides of the outer wall of the cabinet 1, the plurality of heat dissipation holes 24 and the plurality of circulation holes 19 are communicated with the cavity 18;

[0026] Specifically, by starting the fan 17 to generate wind, the interior of the cabinet 1 is cooled through the cavity 18 and the circulation hole 19, and cooperates with the heat dissipation hole 24 to drive the alternation of the air inside and outside the cabinet 1, thereby discharging the heat generated during the purification process inside the cabinet 1 out of the cabinet 1 and lowering its temperature.

[0029] A method for using an electronic-grade xenon gas purification device, comprising the following steps:

[0030] S1. First, the xenon gas is purified by the distillation tower 2. Then, it is purified twice by passing through the gas pipe through the outer tank 4. Then, it enters the freezing bottle 20 through the gas pipe for freezing. Finally, it enters the vacuum filling bottle 23 through the filling pipe to complete the purification operation.

[0031] S2. The fan 17 is started to generate wind, which passes through the cavity 18 and the circulation hole 19 to cool the interior of the cabinet 1. The fan 17 cooperates with the heat dissipation hole 24 to drive the air inside and outside the cabinet 1 to alternate, thereby discharging the heat generated during the purification process in the cabinet 1 from the cabinet 1, lowering its temperature and completing the cooling operation.

[0032] S3. Turn nut 9 to disengage bolt 8, and then turn bolt 8 to disengage flange 1 6 and flange 2 7, thereby separating semicircular connector 1 3, outer tank 4, and semicircular connector 2 5. The filter cotton filled inside can be replaced, completing the filter cotton replacement operation;

[0033] S4. When adding or replacing the purifying agent, based on S3, it is necessary to pull the slide bar 11 to one side to disengage it from the chute 10 on the outer tank 4, so that the upper inner tank 12 and the lower inner tank 13 are separated from the outer tank 4. Subsequently, because the slide bar 11 is no longer limited by the chute 10, the upper inner tank 12 and the lower inner tank 13 can be opened, and the purifying agent inside them can be added or replaced, completing the corresponding operation of the purifying agent.

[0034] Working principle:

[0035] First, the xenon gas is purified by the distillation tower 2 and then enters the semicircular connector 1 3 through the air guide pipe. The filter cotton filled therein can physically filter the xenon gas and remove moisture by adsorption. Then, impurities such as oxygen, nitrogen, and argon in the xenon gas are removed by various purifying agents placed on the layer plate 15, thereby improving the purity of the xenon gas. The xenon gas then flows out through the semicircular connector 2 5 and enters the freezing bottle 20 through the air guide pipe for freezing. The filling pipe and filling bottle 23 are then evacuated by the vacuum pump 22, so that the frozen xenon gas enters the vacuum filling bottle 23 through the filling pipe, completing the operation.

[0036] During the xenon gas purification process, the fan 17 is activated to generate wind, which passes through the cavity 18 and the circulation hole 19 to cool the interior of the cabinet 1. The fan cooperates with the heat dissipation hole 24 to drive the air inside and outside the cabinet 1 to alternate, thereby discharging the heat generated during the purification process from the cabinet 1 and lowering its temperature.

[0037] When the filter cotton needs to be replaced, the nut 9 is turned to disengage it from the bolt 8, and then the bolt 8 is turned to disengage the flange 1 6 and the flange 2 7, thereby separating the semicircular connector 1 3, the outer tank 4 and the semicircular connector 2 5, and the filter cotton filled inside can be replaced;

[0038] When it is necessary to add or replace the purifying agent, on the basis of replacing the filter cotton, pull the slide bar 11 to one side to disengage it from the slide groove 10 on the outer tank 4, so that the upper inner tank 12 and the lower inner tank 13 are separated from the outer tank 4. Then, because the slide bar 11 is no longer limited by the slide groove 10, the upper inner tank 12 and the lower inner tank 13 can be opened, so that the purifying agent inside can be operated. At this point, the entire workflow is completed.

[0039] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
