Description
Technical field
The invention belongs to nuclear pollution decontamination technology field more particularly to a kind of aqueous low surface tension high viscosity radioactivity gas
Colloidal sol depressor and preparation method.
Background technique
Currently, the immediate prior art:
Radioaerosol refers to that easily diffusion is same containing radionuclide or by the aerosol of radionuclide contamination
When can enter human body by respiratory system and cause interior irradiation, therefore in nuclear accident and nuclear emergency response, removal radioactivity gas is molten
Glue stain is all critical issue.
It is usually mainly the method for physical cleaning to the removal processing mode of Conventional aerosol particulate matter (on-radiation), it is main
It to include mechanical dedusting, filtering type dedusting, wet process compacting, electrostatic precipitation these four types.The removal of radioaerosol was both
It is considered as its characteristic as aerosol, and it should be conceived to radioactive special harm.Radioactivity gas is molten in nuclear emergency
The generation of glue has time bursts, place Unpredictability, it is desirable that dedusting technology should have flexibility, mobility, convenient for behaviour
The features such as making.Wet sprinkling dedusting then substantially meets above-mentioned requirements, wet sprinkling dedusting refers to spray liquid is atomized after with dust-laden
Gas comes into full contact with, the method for washing and making gas purification for grit.Spray (mist) though dedusting have it is flexible, motor-driven, just
Meet the requirement removed to radioaerosol in the features such as operation.
But have following both sides insufficient again using water as spray liquid: firstly, after water atomization its drop surface tension
Greatly, it hinders water mist particle and aerosol particles to soak coalescence, reduces removal effect;Followed by after spraying and dedusting, water is due to it
Good fluidity, it is difficult to collect, be easily penetrated into underground after carrying radioaerosol particle secretly, cause the pollution of more depth.
In conclusion problem of the existing technology is:
(1) in the prior art, not over design polymer chain structure, drop has lower after being atomized its aqueous solution
Surface tension (surface energy), it is easier to soak coalescence with aerosol particles, cause to obtain more preferably aerosol compacting effect
Fruit.
(2) in the prior art, it cannot make the depressor of preparation while keeping compared with low surface tension, still have higher
Viscosity, cause spray atomizing dedusting land after mobility it is big, easily collecting, not can effectively solve radioactive diffusion pollution.
(3) the higher surface tension of existing depressor can make liquid-drop diameter after atomization larger, be equivalent in unit volume
The density of atomized drop is small, so that the collision frequency of drop Yu aerosol dust can be reduced, so that compacting efficiency is relatively low.
Solve the difficulty of above-mentioned technical problem:
(1) it selects suitable polymerization system to design polymer chain structure, while guaranteeing that compacting agent solution has well again
Film forming and rippability be one of difficulty of this patent.
(2) its viscosity can be made also to further decrease while reducing depressor solution surface tension under normal conditions, therefore
Prepare a kind of low surface tension and meanwhile have both viscosity higher depressor be this patent difficulty two.
Solve the meaning of above-mentioned technical problem:
One faced in the control of radioactive dust and the removal always elimination of nuclear facilities and nuclear emergency response is important to be asked
Topic, conventional more flexible method predominantly sprays wet process and suppresses decontamination, but the suppression performance of the depressor used at present
It need to be improved.Therefore prepare the radioaerosol depressor of high suppression performance a kind of, to the control of radioaerosol with
Removal has very important meaning.
