Description
Technical field
The utility model belongs to radioactive isotope preparation technical field, and in particular to a kind of I-131 production is inhaled with destructive distillation
Receive device.
Background technique
For producing the Na of radioactive drugs131After I raw material mainly passes through the irradiation of high temperature (about 750 DEG C) dry distillation reactor heap
TeO2(tellurium dioxide) and the radioactivity I in carrier gas is absorbed with sig water (generally NaOH solution of the concentration less than 0.5mol/L)
(iodine) -131 steam is made.Inst. of Nuclear Physics and Chemistry, Chinese Engineering Physics Research Ins, and domestic Chinese atomic energy science
Research institute and Chinese nuclear power research institute, once in its Na131In I production technology by the way of vacuum pump pumping, by retort
Interior high temperature carrier gas is introduced directly into absorption bottle bottom by pipeline and is bubbled, and the iodine -131 steam in carrier gas is turned by the sig water in bottle
Chemical conversion is Na131I solution.But since very high and the absorbing liquid in absorption bottle the small volume of carrier gas temperature (is usually no more than
20mL), it is easy to during iodine -131 is extracted in distillation so that the temperature of absorbing liquid quickly increases and occurs on absorption bottle top
" fog ", and exhaust gas processing device is entered by tail gas carrier band, cause I-131 vapor adsorption inefficiency and absorbing liquid in carrier gas to be steamed
Hair loses more radioiodine, and bigger pressure is also caused for the online processing of tail gas and qualified discharge.Reduce flow rate of carrier gas
Advantageously reducing heat exchange leads to the evaporation of absorbing liquid, but is unfavorable for preventing iodine -131 steam mistake temperature in gas-guide tube from being adsorbed by tube wall
And lose, also it is unfavorable for setting out in time for the intracavitary a large amount of iodine -131s of retort, causes production (distillation or heat preservation) time and carrier gas
The absorbing liquid continuous heating time is extended, and there are the greater risks that iodine -131 steam is leaked from feed inlet, especially in dioxy
Change tellurium and reaches the fusing point moment.Since domestic destructive distillation heap shines TeO2Produce Na131The device of I is all made of vacuum pump pumping and keeps carrying
Gas directed flow, and keep the intracavitary certain negative pressure of retort to prevent iodine -131 vapour leakage, and higher in order to meet product
The requirement of radioactive concentration, the diluted alkaline liquid measure being added in the absorption bottle of tubulose are less.On the other hand, existing heap shines TeO2It is dry
Furnace is without charging and material unloading function online, it is necessary to be down at least 150 DEG C or less (distillations of iodine in upper batch production furnace temperature
Temperature is about 185 DEG C, preferably close to room temperature), it could charge again after taking out residue and carry out lower batch production, batch production time
Often it is no less than 6 hours, and wherein about 80% time is used for furnace body natural cooling.Since iodine is easily evaporated and is inhaled
It is attached, directly the bottoms of high temperature are taken out, or remove the plug of distillation cascade bottoms are placed on nozzle cooling is to be prohibited
, and absorbing liquid evaporation, and high-temperature furnace body holding to distillation cascade and its interior bottoms can be accelerated by improving flow rate of carrier gas
The time of continuous heat supply can't be significantly affected by flow rate of carrier gas, unless using heat-insulated to distillation cascade or furnace body can be made quick
Otherwise the method for heat dissipation is difficult to significantly shorten the production time.Based on previous reasons, the iodine -131 yield of the prior art is often below
90%, the batch production time is long and the risk of iodine -131 vapour leakage pollution environment is higher, is unfavorable for implementing continuous multiple batches of height
Effect, safety in production.Although reducing the temperature of distillation outlet of still carrier gas by using one section of low-temperature space is increased behind high temperature distillation area
Degree is not carried pipe before by lye absorption processing for iodine -131 in guarantee carrier gas to cut down the heating effect to absorbing liquid
Road inner wall is adsorbed and is caused damages, and the temperature general control of carrier gas is still bright to the effect of absorbing liquid heating evaporation at 300 DEG C or so
It is aobvious.Moreover, the distillation cascade of the prior art and absorber be it is split type, connected using plastic tube or rubber tube, the radiation in carrier gas
The intense gamma radiation of property iodine -131 and high temperature have larger impact to the service life of connecting tube, are easy to appear season cracking in practice
And lead to radioactivity iodine -131 vapour leakage accident, it shortens service life and increases production equipment maintenance and repair personnel receiving
The risk of more dose of radiations, is unfavorable for keeping the safety in production.There is efficiently cooling and quickening distillation cascade drop to Alkali absorption liquid using setting
Temperature function, and be suitable for hot cell or shield compact-sized, the small and exquisite distillation cascade and absorber of production environment condition in work box
Integration-in-one destructive distillation absorber is the main path for solving prior art defect.
Summary of the invention
In order to improve Na131The production efficiency of I solution, reduces security risk, and the utility model provides a kind of I-131 production
With destructive distillation absorber.
The destructive distillation absorber of the utility model using compressed air stream it is heat-insulated and to absorbing liquid it is cooling by the way of and distillation cascade
With the structure of absorber integration-in-one, the height distilled from the tellurium dioxide raw material that reactor activates can be efficiently trapped
Warm radioactivity iodine -131 steam, so that the high income of iodine -131 is of about 98%, the batch production time is foreshortened to about 2 hours, extends life
It produces device lifetime and the security risk of production is effectively reduced.
The technical scheme for implementing the utility model is as follows:
