Description
Technical field
The present invention relates to a kind of implementation method for the device that tritium is reclaimed from tritiated water.
Background technology
Tritium technological experiment room can all produce the tritium of different activity under normal operating conditions or tritium leakage emergency processing state
Change water (HTO).Tritium in tritiated water can not be used directly, it is necessary to be translated into elemental tritium (HT), could be used as nuclear fuel
Re-used.Also, tritiated water is easier to be absorbed by human organ relative to elemental tritium, and this can cause bigger radiation
Dosage, its dose factor is 25000 times of simple substance tritium.Therefore, from the aspect of the utilization of resources and Environmental security two, it is necessary to will
Tritiated water is converted into elemental tritium, to realize the recovery of tritium.
At present, the method for tritium is reclaimed from tritiated water mainly following several：Electrolysis, isotope are exchanged, thermometal is decomposed
Method.HTO directly can be converted into HT by electrolysis, and its principle is that water decomposition reaction directly occurs under electric field action：2HTO=

High performance proton membrane and electrode are wanted, technology maturity is not high, also in developing stage.Isotope exchange method uses catalysis
Membrane reactor (PERMCAT) is exchanged, is made up of Pd alloys permeable membrane and catalyst bed.Using isotope exchange principle, containing HTO's
Gas enters catalyst bed, and H2Or CO enters permeable membrane side with counter-flow pattern, per-meate side maintains negative pressure, and reaction principle is：H2+
HTO=H2O+HT or CO+HTO=HT+CO2；HT is enriched in the osmos tube port of export, so as to realize recovery.This method needs high-performance
Permeable membrane and catalyst, cost is higher, and running-course control is complex.
Thermometal method uses the metal or alloy with reproducibility, and its reaction principle is：XM+HTO=MxO+HT.Contain
After HTO gas is by reaction bed, the oxygen in water in the form of metal oxide to be trapped within metal bed, and the hydrogen in water is same
Position element is changed into HT.This method need not introduce the mechanical systems of complexity, low and safe and reliable with small volume, initial input cost
The advantages of.Therefore consider that this method is suitable for from tritiated water reclaiming tritium from economy and technology maturity.But using tradition
Active metal (Mg, Zr etc.) or alloy packing (ZrNi, ZrMnFe etc.), bed body failure after can form solid tritiated waste, increase
Plus subsequent treatment burden；It is therefore desirable to optimize design to this method, and tritium recovery scheme in tritiated water is carried out overall
Design, so as to be not only able to realize the high efficiente callback of tritium, and can avoid producing solid waste.

It is occurred reduction reaction with ferroso-ferric oxide, generate metallic iron, gas is discharged by A1 pipelines.A1 pipelines are provided with humidity sensor
Device, when water content is less than 10ppm, shows that the regeneration of the first water decomposition bed 5 is completed, now, just can stop being passed through for high-purity hydrogen.
First regeneration of adsorbent beds
In the present invention, adsorbent bed using be heated at high temperature and be passed through inert carrier gas purging by the way of regenerated, specifically set
Putting is：Valve also is provided with pipeline between surge tank 3 and tritiated water storage tank 4, and the valve both sides are equipped with as suction
The branch road of attached bed regenerative circuit, wherein, the branch road close to surge tank 3 is simultaneously respective with the first adsorbent bed 7 and the second adsorbent bed 8
Gas outlet is connected, and close to tritiated water storage tank 4 branch road then simultaneously with the first adsorbent bed 7 and the second adsorbent bed 8 it is respective enter
Gas port is connected.
When the first adsorbent bed 7 needs regeneration, the input of the first adsorbent bed 7 and the respective valve of output end are closed, is opened
The input of second adsorbent bed 8 and the respective valve of output end, make gas containing hydrogen tritide enter in the second adsorbent bed 8, by the second absorption
Bed 8 continues to adsorb water vapour.Meanwhile, open connection the first adsorbent bed regenerative circuit on valve, close surge tank 3 with it is tritiated
Valve between water storage tank 4 on main pipeline, is heated to more than 300 DEG C by the first absorption bed tempertaure, makes dry inert carrier gas
First adsorbent bed (the B2 pipelines in Fig. 3 enter, B1 pipelines go out) is entered with opposite airflow direction, the tritiated water feeding desorbed
Into tritiated storage tank 4, while regenerating it.The water content in the pipeline of inert carrier gas circulation is detected using humidity sensor,
When water content is less than 10ppm, then shows the regeneration completion of the first adsorbent bed 7, stop the infeed of inert carrier gas.
The bed regeneration of first hydrogen storage
The first hydrogen storage 9 inputs of bed and the respective valve of output end are closed, the second hydrogen storage 10 inputs of bed and output is opened
Respective valve is held, the gas containing hydrogen tritide of drying is entered in the second hydrogen storage bed 10, continuing absorption by the second hydrogen storage bed 10 contains tritium
Hydrogen.Meanwhile, the first hydrogen storage 9 temperature of bed are heated to 300~500 DEG C, it is gaseous state gas containing hydrogen tritide to make the thermal desorption of aspiration containing hydrogen tritide,
Maintenance system pressure is less than 1atm, then by the C pipelines in Fig. 3, and hydrogen is outwards shifted from the first hydrogen storage bed 9, makes the
One hydrogen storage bed 9 regenerates.
