[0071] In an exemplary embodiment, the particle size measurement laser emitting surface 109 and the particle size measurement laser receiving surface 108 are arranged opposite to each other, and the particle size measurement laser emitting surface 109 and the particle size measurement laser receiving surface 108 are parallel to each other. Figure 3 shown.

[0072] In an exemplary embodiment, a laser emission interface is also provided on the particle size measurement laser receiving surface 108, such as Figure 3 shown.

[0073] In an exemplary embodiment, the laser beam emitted by the laser emission interface is parallel to the laser beam emitted by the particle size measurement laser emission surface 109. Figure 3 shown.

[0074] In an exemplary embodiment, a particle size measurement receiving position is further provided on the particle size measurement laser receiving surface 108 .

[0075] In an exemplary embodiment, the particle size measurement receiving position is used to receive the laser beam emitted from the particle size measurement laser emitting surface 109 .

[0076] In an exemplary embodiment, the observation surface 106 and the particle size measurement laser receiving surface 108 are perpendicular to each other.

[0077] In an exemplary embodiment, the sampling surface 107 is disposed between the observation surface 106 and the particle size measurement laser receiving surface 108 .

[0082] In an exemplary embodiment, the number of observation surfaces 106 is less than the number of sampling surfaces 107 .

[0083] In an exemplary embodiment, a uranium hexafluoride inlet is provided on one end face of the polygonal column 101 , for example, the uranium hexafluoride inlet is provided on the right end face of the polygonal column 101 .

[0084] In an exemplary embodiment, the uranium hexafluoride inlet is externally connected to a uranium hexafluoride release pipeline 102 .

[0085] In an exemplary embodiment, a uranium hexafluoride inlet is in communication with the chamber.

[0086] In an exemplary embodiment, a mixed gas outlet is provided on the end face opposite to the end face provided with the uranium hexafluoride inlet. For example, if the uranium hexafluoride inlet is provided on the right end face, the mixed gas outlet is provided on the left end face.

[0087] In an exemplary embodiment, the mixed gas outlet is connected to a condensation system and a leaching tower filtration system as needed, and the mixed gas is discharged after being filtered and treated to meet the standards.

[0088] In an exemplary embodiment, the uranium hexafluoride leakage experimental device based on a multi-prism according to an embodiment of the present application further includes: a water vapor pipeline 104 .

[0089] In an exemplary embodiment, the water vapor pipeline 104 is connected to the same end face as the uranium hexafluoride inlet; that is, when the uranium hexafluoride inlet is disposed on the right end face of the polygonal column 101 , the right end face is also connected to the water vapor pipeline 104 .

[0090] In an exemplary embodiment, a water vapor line 104 is in communication with the chamber.

[0091] In an exemplary embodiment, the axis of the uranium hexafluoride release pipeline 102 coincides with the axis of the polygonal column 101. The purpose of setting the axis coincidence is to provide optimal space for subsequent reactions of uranium hexafluoride and to avoid the uranium hexafluoride being directly attached to the side wall when it is set on the side, thereby affecting the reaction effect.

[0092] In an exemplary embodiment, the water vapor pipeline 104 is connected to the right end surface of the polygonal column 101 through the water vapor pipeline outlet 201 .

[0093] In an exemplary embodiment, the water vapor pipeline outlet 201 is sleeved on the uranium hexafluoride inlet.

[0094] In an exemplary embodiment, the axis of the water vapor pipeline outlet 201 coincides with the axis of the uranium hexafluoride inlet. This design allows a more complete reaction between uranium hexafluoride and water.

[0095] In an exemplary embodiment, a heating layer 202 is further provided on the outer layer of the uranium hexafluoride release pipeline 102 .

[0096] In an exemplary embodiment, the heating layer 202 is used to heat the temperature of the uranium hexafluoride in the uranium hexafluoride release pipeline 102 to the triple point temperature.

[0097] In an exemplary embodiment, the triple point temperature of uranium hexafluoride is at 64°C.

[0098] In an exemplary embodiment, on the right end face of the polygonal column 101 , the uranium hexafluoride release pipeline is covered with a heating layer 202 , and the water vapor pipeline outlet 201 is covered outside the heating layer 202 .

[0099] In an exemplary embodiment, the water vapor pipeline 104 includes a U-shaped tube, which can be understood as the water vapor pipeline 104 is provided with a U-shaped tube, and the number of the U-shaped tubes can be one or more as needed.

[0100] In an exemplary embodiment, the U-shaped tube is designed to prevent the uranium hexafluoride from reacting with water vapor or not reacting in time from invading the humidifier 103 along the water vapor pipeline 104, thereby damaging the humidifier 103. Due to the design of the U-shaped tube, water vapor will accumulate a certain amount of liquid water at the U-shaped tube, and the uranium hexafluoride invading the water vapor pipeline will be intercepted and reacted, thereby preventing the uranium hexafluoride from continuing to invading the humidifier 103.

[0101] In an exemplary embodiment, a humidifying device 103 is connected to the end of the water vapor pipeline 104 .

[0102] In an exemplary embodiment, the humidifier 103 is used to provide water vapor to the water vapor pipeline 104 . The humidifier 103 heats the water inside to convert it into water vapor and provides water vapor to the water vapor pipeline 104 as needed.

[0103] In an exemplary embodiment, the edge length of the polygonal column 101 is, for example, 150 mm.

[0104] In an exemplary embodiment, when the uranium hexafluoride gas in the uranium hexafluoride release pipeline and the water vapor in the water vapor pipeline 104 simultaneously enter the chamber of the polygonal column 101, the PIV measurement system monitors temperature, humidity, pressure, flow field, hydrogen fluoride concentration, etc.

[0105] In an exemplary embodiment, the PIV measurement system is a particle image velocity measurement system (PIV).

[0106] In an exemplary embodiment, Figure 3 As shown, taking the polyhedron 101 as an octagonal prism as an example, the four sides of the octagonal prism are sampling surfaces 107, and the four sampling surfaces 107 are not adjacent to each other, and sampling interfaces 105 are provided on the sampling surfaces 107. Two of the remaining four sides are observation surfaces 106, and the two observation surfaces 106 are arranged opposite to each other. The remaining two sides are particle size measurement laser emitting surfaces 109 and particle size measurement laser receiving surfaces 108. The observation surfaces 106 are used to observe the state of uranium hexafluoride after reaction with water vapor under laser irradiation. The design that the observation surface 106 is perpendicular to the laser emitting direction is to better observe the effect after laser irradiation.

[0107] In an exemplary embodiment, the laser emission interface is preferably disposed at the geometric center of the particle size measurement laser receiving surface 108, and the observation position on the observation surface 106 corresponds to the position of the laser emission interface.

[0108] In an exemplary embodiment, the observation position on the observation surface 106 corresponds to the position of the laser emission interface, which can be understood as the position of the laser emission interface and the plane where the observation position is located are perpendicular to the central axis of the polygonal column 101 .

[0109] In an exemplary embodiment, when the PIV measurement system is in use, the particle size measurement laser emission line is preferably arranged in parallel with the laser emission line of the PIV measurement system; it can be understood that the particle size measurement position of the particle size measurement laser emission line on the particle size measurement laser emission surface 109 is, for example, Figure 3 As shown; the laser emission line of the PIV measurement system works in a direction perpendicular to the particle size measurement laser emission surface 109 at the laser emission interface of the particle size measurement laser receiving surface 108.

[0110] In an exemplary embodiment, the side surfaces of the polygonal column 101 in this embodiment are all surfaces formed between adjacent side edges.
