Technical Field

[0001] The utility model relates to a krypton-xenon extraction process, in particular to a radon removal machine for a krypton-xenon extraction process. Background Art

[0002] The radon removal technology in the krypton-xenon extraction process effectively removes the radioactive radon element in the krypton-xenon mixture by using specific devices and processes. Among them, the condensation method for radon removal is one of the common methods. The condensation method uses low-temperature conditions to liquefy radon, so as to separate it from the krypton-xenon gas. The krypton-xenon mixed gas is introduced into the condensation device, and the temperature is reduced to liquefy and collect radon. The condensed liquid radon can be further processed or stored, while the remaining krypton-xenon gas continues with the subsequent purification steps. Reference can be made to the patent publication number: CN 219913696 U - a Chinese utility model patent, a radon removal machine for a krypton-xenon extraction process. Although the retention time of the krypton-xenon mixed gas in the inner shell in the above patent is short, and it is difficult to completely condense the radon in the krypton-xenon in a short time, however, the residence time of the radon in the krypton-xenon in the machine shell is still too short, and the radon removal effect is not ideal. Summary of the Utility Model

A certain distance is reserved between each second plate and the inner top wall of the machine shell, and the second plates are arranged in a cross manner with the plurality of first plates. Each of the second plates is fixedly provided with a cooling pipe;

[0009] The plurality of first plates and the plurality of second plates form a serpentine channel in the machine shell. The head end of the serpentine channel is communicated with the air inlet pipe, and the tail end is communicated with the air outlet pipe.

[0035] The following combines the drawings in the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0036] Embodiment:

[0037] As Figures 1 - 3 shown, this embodiment provides a radon removal machine for krypton-xenon extraction process, including a housing 1, a partition board 4 and a cooling pipe 6. The housing 1 has a sandwich structure (not shown), and a lead plate (not shown) is fixedly arranged in the sandwich structure. The lead plate is used to isolate the radiation generated by the decay of radon isotopes. The two ends of the housing 1 are respectively connected to the inlet pipe 2 and the outlet pipe 3. The partition board 4 is fixedly arranged in the housing 1, and the partition board 4 divides the housing 1 into an upper cavity 10 and a lower cavity 11. In addition, the lower cavity 11 is regarded as a liquid radon collection space, and the lower cavity 11 is connected to an output pipe (not shown). As Figure 2 shown, a plurality of first plate bodies 5 are fixedly arranged along the length direction of the inner top wall of the housing 1, and a certain distance is reserved between the bottom end of each first plate body 5 and the partition board 4. The radon removal machine for krypton-xenon extraction process further includes a refrigeration main body (not shown), and the refrigeration main body is connected to a plurality of cooling pipes 6. The refrigeration main body adopts the prior art, so no more details will be described. The refrigeration main body can provide refrigeration for the cooling pipes 6, such as compressor refrigeration. A plurality of second plate bodies 7 are fixedly arranged along the length direction of the top wall of the partition board 4, and a certain distance is reserved between the top end of each second plate body 7 and the inner top wall of the housing 1, and each second plate body 7 is arranged in a cross manner with a plurality of first plate bodies 5. As Figure 3As shown, a cooling pipe 6 is fixedly arranged on each second plate body 7. The cooling pipe 6 is made of copper. A plurality of first plate bodies 5 and a plurality of second plate bodies 7 form a serpentine channel 8 in the casing 1. The head end of the serpentine channel 8 is communicated with the intake pipe 2, and the tail end of the serpentine channel 8 is communicated with the exhaust pipe 3.

[0038] Drive the plurality of cooling pipes 6 to start working. The krypton-xenon mixed gas enters the serpentine channel 8 through the intake pipe 2. The krypton-xenon mixed gas flows along the serpentine channel 8. Each first plate body 5 is fixedly provided with a cooling pipe 6, so that the temperature of the serpentine channel 8 is reduced. The reduced temperature causes radon to change from a gaseous state to a liquid state. The liquid radon is separated from the krypton-xenon mixed gas. The liquid radon drops onto the partition plate 4. The krypton-xenon mixed gas continues to flow along the serpentine channel 8. Among them, the krypton-xenon mixed gas flows in the serpentine channel 8, and the krypton-xenon mixed gas stays in a colder space for a long time, further improving the radon removal effect of the krypton-xenon gas.

[0039] As Figure 2 、 Figure 3 As shown, liquid leakage grooves 40 are opened on the partition plate 4 on both sides of each second plate body 7. The plurality of liquid leakage grooves 40 are all communicated with the lower cavity 11, and a switching valve 9 is arranged on each of the plurality of liquid leakage grooves 40. The switching valve 9 includes two plug plates 91 and two cylinders 92, which correspond to each other one by one. Each liquid leakage groove 40 communicates with two guide grooves 41. The two guide grooves 41 extend outside the casing 1 and correspond to the two plug plates 91 one by one. The plug plates 91 are slidably arranged in the guide grooves 41. The cylinder block of the cylinder 92 is fixedly connected to the casing 1, and the piston rod of the cylinder 92 is fixedly connected to the plug plate 91 through a connecting rod 93. Among them, the two plug plates 91 are arranged in an up-and-down arrangement.

[0040] The reduced temperature causes radon to change from a gaseous state to a liquid state. The liquid radon is separated from the krypton-xenon mixed gas. The liquid radon drops onto the partition plate 4. When the liquid radon accumulates to a certain amount, drive the upper cylinder 92. The piston rod of the upper cylinder 92 extends, so that the upper plug plate 91 gradually opens. The liquid radon flows into the liquid leakage groove 40. The upper plug plate 91 resets and closes. Drive the piston rod of the lower cylinder 92 to extend, so that the lower plug plate 91 gradually opens. The liquid radon in the liquid leakage groove 40 flows into the lower cavity 11. Through such a structural arrangement, it is avoided that when the liquid radon transfers from the upper cavity 10 to the lower cavity 11, the krypton-xenon mixed gas is transferred to the lower cavity 11 together.

[0041] As Figure 3 As shown, each first plate body 5 is provided with a serpentine groove 51 along the width direction of the casing 1. The cooling pipe 6 is laid along the serpentine groove 51. It is convenient for the liquid radon to flow down from the first plate body 5.

[0042] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model.
