Description

Technical Field

[0001] This application relates to the field of cesium iodide preparation technology, and in particular to a purification apparatus. Background Technology

[0002] Cesium iodide is a colorless crystal or white powder with a density of 4.51 g / cm³, a melting point of 621°C, a boiling point of approximately 1280°C, and a refractive index of 1.7876. It is irritating. Cesium iodide is a colorless crystal or white powder with a density of 4.51 g / cm³, a melting point of 621°C, and a boiling point of 1280°C. It is soluble in water and alcohols. Cesium iodide produces a sky-blue flame when burned. Cesium iodide scintillation crystals absorb external radiation energy, ionizing and exciting atoms and molecules, and emitting fluorescent photons upon de-excitation. Due to its high density and the fact that iodine with high atomic numbers accounts for 85% of its weight, it has particularly high detection efficiency for gamma rays and a high relative luminous efficiency; its strongest emission wavelength is around 415 nm, which matches well with the spectral response of photomultiplier tubes. In addition, the crystal has excellent transparency and is one of the best scintillators in terms of energy resolution when measuring gamma rays.

[0003] Current equipment for liquefying and purifying cesium iodide has drawbacks such as low efficiency and low purification purity. Therefore, there is an urgent need in the market to develop a purification device. Utility Model Content

[0030] Example

[0031] To address the shortcomings of existing liquefaction and purification equipment for cesium iodide, such as low efficiency and low purification purity, this paper refers to... Figure 1 and Figure 2 As shown, this application discloses a purification apparatus, including a distillation system 10 and a condensation system 20;

[0032] The distillation system 10 includes a tank 11, a cover 12, and a reaction vessel 13. The tank 11 has a first water inlet and a first water outlet on its upper and lower sides, respectively. A heating coil 14 is installed on the inner bottom wall of the tank 11. The reaction vessel 13 is suspended inside the tank 11. The upper and lower sides of the reaction vessel 13 have a feed pipe 131 and a discharge pipe 132 extending outward from the tank 11, respectively. A stirring plate 15 is installed inside the reaction vessel 13. A power motor 16 is installed outside the tank 11, and its output shaft passes through the reaction vessel 13 and is connected to the stirring plate 15. The cover 12 is located above the tank 11.

[0033] The condensation system 20 includes a condenser cylinder 21 and a condenser coil 22. The condenser cylinder 21 is located above the cover 12. The upper and lower sides of the condenser cylinder 21 are respectively provided with a second water inlet and a second water outlet. The condenser coil 22 is located inside the condenser cylinder 21 and passes through the tank 11 to connect with the reaction vessel 13.

[0034] In addition, the tank body 11 is provided with a collection chamber 30 connected to the condenser coil 22.

[0035] Based on the above purification equipment, when purifying cesium iodide, the cesium iodide raw material is first fed into the reaction vessel 13 through the feed pipe 131. Water for heating is injected into the tank 11 through the first water inlet to control the heating of the distillation coil, and water for cooling is injected into the cooling coil through the second water inlet. Then, the stirring plate 15 is driven by the power motor 16 to rotate in the distillation plate. During this process, the cesium iodide in the reaction vessel 13 will rise in a gaseous state to the condensation coil 22, and will be converted into liquid by the cooling water and fall into the collection chamber 30.

[0036] In one embodiment, the present application has an annular step 111 integrally formed on the inner side wall of the tank 11, and a disc 133 integrally formed on the outside of the reaction vessel 13. The disc 133 and the annular step 111 are fixed by screws 40. Several water passage grooves 1331 are formed on the surface of the disc 133. This method facilitates quick assembly and disassembly of the reaction vessel 13 and the tank 11. In addition, by forming water passage grooves 1331 on the surface of the disc 133, it is possible to ensure that the hot water in the tank 11 flows upward, thereby covering the reaction vessel 13.

[0037] In a preferred embodiment, in order to enable the power motor 16 to drive the stirring plate 15 to rotate inside the reaction vessel 13 under sealed conditions, this application provides sealed bearings 70 inside both the tank body 11 and the reaction vessel 13. The output shaft of the power motor 16 passes through the sealed bearings 70 and is connected to the stirring plate 15. By connecting the stirring plate 15 to the power motor 16 through the sealed shaft, the stability of rotation can be guaranteed, which has high practicality.

[0038] In some other necessary embodiments, this application also installs a first solenoid valve 50 at the connection between the discharge pipe 132 and the tank 11. After the distillation is completed, the first solenoid valve 50 is opened and the unevaporated material in the reaction vessel 13 is automatically discharged.

[0039] In some other necessary embodiments, a second solenoid valve 60 is installed at the first water inlet, the second water inlet, the first water outlet, and the second water outlet of this application. When water is injected into or drained from the tank 11 or the cooling cylinder, the corresponding second solenoid valve 60 can be controlled, which is convenient and quick to operate.

[0040] In some preferred embodiments, the condenser coil 22 of this application is provided with an inverted L-shaped tube 23 outside the condenser cylinder 21. The inverted L-shaped tube 23 passes through the tank body 11 and is connected to the reaction vessel 13. A one-way valve 24 is installed at the connection of the condenser coil 22 and the inverted L-shaped tube 23. In practice, under the control of the one-way valve 24, the cesium iodide gas generated by distillation in the reaction vessel 13 can only flow upward to the condenser coil and will not flow back.
