Abstract
The utility model discloses a dry distiller for producing radioactive iodine 131 I, comprising a crucible furnace, a TeO2 target container, a distilling vessel, a gas collection cap, an iodine absorber, etc. The utility model is characterized in that the crucible furnace is vertically and reversedly arranged on the upper part of the distilling vessel; the distilling vessel is formed by that a casing in a bell shape is covered on a seat and grinding mouths are tightly contacted; the seat is divided into an upper part and a lower apart, which are separated by a partition board; the upper part of the seat is of a protective seat of the target container; the circumference walls on the upper part of the tightly contacted position of the seat and the casing of the bell are provided with air holes; the lower part of the seat is provided with air intake tubes; the dry distillated 131I is driven into the iodine absorber by sucking and gas carrying device with negative pressure. The utility model has the advantages of safety, reliability, and no radioactive gas leakage.
Description
The utility model belongs to the preparation apparatus field of radionuclide, relates in particular to a kind of radionuclide
131The distillation apparatus of I.
At present, be used to produce radionuclide
131The distillation apparatus of I can be divided into horizontal and vertical two kinds, adopts horizontal the heating with vertical heater to place pottery or the interior irradiated tellurium target of quartz apparatus respectively, and high temperature down will
131The destructive distillation of I nucleic is come out, and adopts negative pressure-pumping or carrier gas carrier band extremely
131The absorption system of I.Because
131I is the gaseous state radionuclide, therefore when the equipment of this product is produced in design, must double to consider its security, reducing to minimum degree to the pollution that surrounding environment produces.Canada discloses in the patent 1193599 of Britain application a kind ofly heats irradiated tellurium target with vertical heater, and the quartz apparatus of putting the tellurium target is sent in the quartzy distil container from top to bottom, seals distil container, and high temperature down will
131The I destructive distillation is come out, and uses the carrier gas carrier band to absorption system; The device of the former German Democratic Republic of document " Radioisotope and Rad-sopharmaceutical production in vietnam " by LE VAN SO report, be that the quartz apparatus of dress tellurium target is sent in the stove in the quartz still from top to bottom, cover upper cover in the above, adopt negative pressure-pumping that atmosphere is sucked in the distillation system, with dried distilled under the high temperature by sealing part
131I nucleic carrier band is to the iodine absorption system.More than the device weak point is that safety performance is not good enough.
The purpose of this utility model provides the device that a kind of safety performance is higher than existing installation, makes the production safety and reliability.
The technical solution of the utility model is as follows:
1. produce radionuclide for one kind
131The distillation apparatus of I comprises crucible oven, contains TeO
2The target container, distil container, gas collection cap,
131The I resorber, inlet pipe, it is erect-type being characterized as crucible oven, tips upside down on the distil container top; Distil container is closely covered on the base by bell jar type shell and constitutes, and base divides two parts up and down, and the centre is separated by with a dividing plate, and top is the protection seat of target container; Be positioned on the base and bell jar type shell driving fit place top, wall evenly has pore all around, and inlet pipe is arranged at the bottom; If bell jar type internal diameter of outer cover is φ d, the protection seat external diameter of target container is φ c, and the target inside diameter of vessel is φ b, and the cover mouth external diameter of gas collection cap is φ a, then has
φa／(φb-φa)=9-11， φc／(φd-φc)=7-9。
Between the bell jar type shell of distil container and base with ground driving fit mutually.
Advantage of the present utility model is: this device has been taked relative measures owing to considered the possibility that multiple radioactive gas escapes, and makes device in use, does not have
131I escapes to surrounding environment, also can not pollute miscellaneous equipment, and is safe and reliable,
131The collection rate of I reaches more than 90%.
The utility model drawings attached 1, Fig. 1 are the utility model front view.
Embodiment:
A kind of production radionuclide
131The distillation apparatus of I comprises crucible oven 1, contains TeO
2 Target container 2, distil container 9, gas collection cap 5,
131I resorber 11, inlet pipe 8, crucible oven 1 is erect-type distil container 9 tops that tip upside down on; Distil container 9 is closely covered on the base 7 by bell jar type shell 6 and constitutes, and base is two portions about in the of 7 minutes, and the centre is separated by with a dividing plate 4, and top is the protection seat 3 of target container 2; On base 7, with bell jar type shell driving fit place top, wall evenly has pore 10 all around, and inlet pipe 8 is arranged at the bottom; If bell jar type shell 6 internal diameters are φ d, protection seat 3 external diameters of target container 2 are φ c, and target container 2 internal diameters are φ b, and the cover mouth external diameter of gas collection cap 5 is φ a, then has
φa／(φb-φa)＝10 φc／(φd-φc)＝8。
7 of the bell jar type shell 6 and the bases of distil container 9 are with ground driving fit mutually.
This device working process is as follows:
Purify pumping speed that carrier gas divides with 100ml/ and suck quartzy distil container 9 from inlet pipe 8 negative pressure of whole device pedestal 7 bottoms, and the parallel channels that the pore 10 on the wall enters between bell jar type shell 6 and the base 7 around base 7 and the 6 ground driving fits of the bell jar shell top is up, in stove, obtain simultaneously preheating, the negative pressure of the air inlet mouth of pipe 8 is maintained at about the 0.09MPa carrier gas and goes upward to bell jar type shell 6 tops, and the narrow gap by 2 in inverted gas collection cap 5 and quartzy target container enters irradiated TeO is housed
2 Target container 2, with the upwards ascension naturally of dried distilled heat in the container 2
131The I radioactive gas makes progress carrier band to iodine scavenger 11 along collecting hood 5.Because carrier gas obtains preheating before entering target container 2, makes the ongoing dry distillation reactor of unlikely influence.Because during design, the distance between 2 in collecting hood 5 and target container and base 7 and bell jar type shell wall is less, carrier gas stream is bigger in this speed, and this two place may be caused
131The access security that I escapes improves greatly, adds upper inverted bell shell 6 and is connected with the ground of 7 of bases, has also prevented
131I escapes from here.When target container protection seat 3 broke at contingency target container 2, the protection radioactive substance can not overflow and contaminated equipment.
