Description
Technical field
It the utility model is related to radioactivity medical waste water process field, more particularly to a kind of decaying device.
Background technology
With the development of medical science, large-scale nuclear medical diagnostic equipment SEPCT, PET/CT etc. use, and it is swollen
The RITs of the diseases such as knurl, thyroid disease radioiodine therapy etc., medical-isotope use more and more.Constitutional law
Strict regulations are advised, hospital uses radio isotope, and pollutant has to pass through specially treated, and immobilization of radioactive waste needs special
Storage, radioactive wastewater is introduced into special treatment tank could be entered after 10 half-life period of standing by general medical waste water
Hospital's sewer.By contained ray type in sewage, the class radioactive dirty water of α, β, γ tri- is further divided into.
However, the radioactive dirty water processing pond of most of hospitals is only a treatment tank at present, constantly to pond
The new radioactive dirty water of injection, confuses old sewage and is discharged into hospital's sewer together in sub, can not really allow sewage to meet storage
10 half-life period and the requirement of the above, if discharge of wastewater can be caused into Environment pollution within 10 half-life period.
Utility model content
The purpose of this utility model is to provide a kind of decaying device, which solves the radioactive dirty water newly injected and old dirt
Water mixes, the problem of not reaching emission request, has and is carried out again after 10 half-life period are more sufficiently passed through to radioactive dirty water
The advantages of discharge and subsequent treatment.
Above-mentioned technical purpose of the present utility model technical scheme is that：

Decay chamber away from filter chamber streams.When old medical radioactive waste water do not stand also reach 10 half-life period and more than, but
, can be by the first electrically operated valve and the first connecting tube, by filter chamber when new medical radioactive waste water is passed through into filter chamber
The interior waste water by filtering is largely drained into cushion chamber so that filter chamber is vacated, and can be discharged into new medical radiation thereto
Property waste water, and when the height of new waste water is maintained at less than the first discharging tube, new waste water can be made to be divided with old waste water
From.And because the difference in height between the mouth of pipe of the first discharging tube and the second discharging tube is 10-20cm, contribute to useless in cushion chamber
Water gradually flow to the decay intracavitary close to cushion chamber, is formed and mixed with the waste water for the intracavitary that decays, when old medical radioactive waste water
After standing reaches 10 half-life period and the above, drawn it out by extraction unit, medical radioactive waste water is more fully led to
Cross 10 half-life period and more than, be not easy to damage to environment and the mankind, and help to carry out follow-up processing work.
More preferably：Vertical distance is provided between first discharging tube and cushion chamber bottom.
Using said structure, when the medical radioactive waste water Jing Guo filtration treatment enters cushion chamber by the first discharging tube
When, it can more stably enter, be not easy the side wall top for making waste water splash to cushion chamber.
More preferably：Second discharging tube is connected with decay cavity wall, and the termination of second discharging tube is with declining
Change is provided with vertical distance between the portion of bottom of chamber.
Using said structure, spiral helicine second discharging tube can make to be discharged into the stationarity that waste water therein keeps good,
If wherein still there is impurity, the gap between termination and decay bottom of chamber portion is with being not easy the waste water and impurity that are discharged end
Block.
More preferably：The 4th connecting tube and the 4th electrically operated valve are provided between the adjacent decay chamber.
Using said structure, when the water level of decay intracavitary it is not high enough and be difficult to by the water of inside continue to flow into it is next and its
During the decay chamber of parallel connection, the 4th electrically operated valve and the 4th connecting tube help to be shifted waste water, also allow for making waste water progressively
Discharged by decaying chamber.
More preferably：Closure is provided with the casing, fixture block is vertically provided with the closure,
Neck is provided with the casing, the neck closely abuts with fixture block.
Using said structure, by fixture block can neck, closure can be closely connected with casing, reduces inner radiation thing
Confrontation external influence, help to protect the health of the mankind and environment.And when waste water stands 10 half-life period and the above, incited somebody to action
After waste water in filter chamber is also fully discharged, barrier can be taken out and be changed, to reach the effect of better filtering and impurity removing matter
Fruit, make subsequent operation simpler.
More preferably：The extraction unit includes the 5th connecting tube, the suction pump and drain valve being arranged in connecting tube
Door.
Using said structure, when medical radioactive waste water was fully stood up to 10 half-life period and the above, by drawing water
Pump, vent valves, connecting tube, waste water is discharged, and is carried out subsequent operation, is not easy to damage to environment and human body, and
Contribute to follow-up processing.
In summary, the utility model has the advantages that：
Medical radioactive sewage is discharged again after more sufficiently passing through 10 half-life period or subsequent treatment, reduce doctor
With harm of the radioactive dirty water to external environment or human body.
