Embodiment 1

[0032] A sort of 89 SrCl 2 The solution concentration device includes a crushing device 1 , a filtering device 2 , a storage device 3 , a heating device 4 , a condensation device 5 , a waste liquid bottle 6 and a sampling device 7 .

[0033] Wherein, the storage device 3 is a three-necked bottle, and there are three outlets on the three-necked bottle, the first outlet communicates with the outlet of the filter device 2, the second outlet communicates with the waste liquid bottle 6 through the condensation device 5, and the third outlet communicates with the sampling device 7 connected, such as figure 1 shown.

[0034] In this embodiment, the waste liquid bottle 6 is also provided with a vacuum pump 8, and the interface of the whole device of the present invention adopts a ground design, which can ensure good air tightness and is suitable for quick assembly and installation.

[0035] Concentration process of the present invention is:

[0036] The first step is to move the c...

Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 is that the structure of the present invention is optimized in this embodiment, and the specific settings are as follows:

[0045] The outlet of the filter device 2 is also provided with a connecting pipe communicating with the waste liquid bottle 6. Through the arrangement of this structure, the liquid of the cleaning filter device can be collected directly into the waste liquid bottle 6, reducing the amount of radioactive waste produced. The waste liquid bottle 6 is also communicated with a cleaning device 9 for cleaning the quartz tube target.

[0046] The filter device 2 is also provided with an air extraction interface, through which the air extraction interface can be used for suction filtration, and the filtration speed is faster. The material of the three-necked bottle is glass and quartz, and the three-necked bottle has volume scale marks.

Abstract

The invention discloses a 89SrC12 solution concentration device. The problems that in the prior art, the concentrations of 89SrC12 solutions are lower, so that many resources need to be occupied by package and transportation, much radioactive waste liquid is generated, the production cost is higher, and the like are solved. The 89SrC12 solution concentration device comprises a crushing device, a filtering device and a storage device which are communicated in sequence; the storage device is a three-neck bottle, a heating device which heats the three-neck bottle is arranged at the bottom end ofthe three-neck bottle, an outlet of the three-neck bottle is communicated with the filtering device, a waste liquid bottle communicated with the three-neck bottle through a condensation device is arranged on another outlet of the three-neck bottle, and a final outlet of the three-neck bottle is communicated with a sampling device. By means of the 89SrC12 solution concentration device, the concentration of a 89SrC12 solution can be effectively improved, and the cost can be reduced.

Description

technical field [0001] The invention relates to the field of nuclear chemical industry, in particular to a device for concentrating 89SrCl2 solution and a concentrating method thereof. Background technique [0002] Irradiation by thermal neutrons inside the reactor 88 SrCO 3 get 89 Sr, and then use a mechanical device to clean and crush the target tube to obtain 89 SrCO 3 Raw materials, then dissolved in hydrochloric acid 89 SrCO 3 get 89 SrCl 2 solution, which can be used as the raw material for strontium chloride [strontium-89] injection. [0003] An existing patent document discloses a 89 SrCl 2 Solution production device, which realizes strontium carbonate obtained after irradiation [ 89 Sr] powder is obtained from the target tube, dissolved, filtered, and subpackaged to obtain 89 SrCl 2 The specific process of the solution, but the concentration of the solution obtained by the process device is less than 10mCi / mL, and the packaging and transportation of the...
