Description
Technical field
Pressed material is controlled the present invention relates to one kind, more particularly, to a kind of compacting of radioactive nucleus pollutant diffusive migration
Material and drawing method.
Background technology
It is known, nuclear accident trigger aerial radioactivity plume disperse, due to gravitational settling, dry deposition, wet deposition work
With in ground surface formation radioactive substance decanting zone, being damaged to ground surface environment and people, the living environment of animals and plants；From should
Anxious consequence control is with from the aspects of compacting, open area and the class of building dense area two are divided into by sedimentation, and suitable development is extensive, fast
The decanting zone of fast Engineering Control operation is referred to as open area, and region in addition is commonly referred to as building dense area.
Open area includes airport, harbour, highway, provincial highway, 1000m2The large-scale square of above area, farmland, grassland,
The radioactive substance deposited on the regions such as forest, the region substantially flexibility radioactive pollution, is highly susceptible to wind, drop
The influence of water and artificial disturbance and settling flux, thus the fixation of radioactive pollution in emergency disposal phase deposition on the ground and
The anti-suspension of non-proliferation is known as the most important thing of consequence compacting action, and the implementation of the anti-suspension measure of fixed non-proliferation is considered as the later stage
Removing, transfer, volume reduction, the emergency disposal measure for concentrating the pollutions such as storage of live radioactive pollution；Open area terrestrial radio
The quick compacting of precipitum and fixed Method means are varied, and these technologies and method are not to suppress objects all to all
Effectively, it is necessary to be made a choice according to different objects and emergent different phase, site conditions, selection technique method and apparatus is used
The mode of highest benefit lowest costs, from reducing general impacts to greatest extent and to factors such as the net loss of personnel evils, reach most
Good population equilibrium.
Open area ground nuclear polluted dust particles diffusion migrates quick control compacting and generally used radioactive dust
The method that grain is quickly suppressed, the method traditionally used has following several：（1）Water jetting；（2）Shoveling principle；（3）Turn over method；Pass
The drawbacks of system nuclear pollution diffusion control method, is mainly reflected in the following aspects：（1）Top layer migration control effect does not reach should
Anxious disposal is required, otherwise costly；（2）Script solid fraction nuclear pollution thing is converted into good fluidity, disposes more difficult waste water, core
Fixation, the migration control of pollution are extremely difficult；（3）Easily cause secondary or secondary pollution；（4）Nuclear pollution compacting is not thorough；（5）It is useless
Object amount is big, and transport, storage or disposal costs are high；（6）Operating efficiency is low, and the disposal cycle is long, and personnel's radioactive dose is big, it is necessary to heavy
Radiation-protection equipment；These drawbacks greatly limit these conventional methods and suppress field in open area ground emergency flight control
Using；Application No.：201410060571.0, it is entitled：Exfoliated compacting depressor；And Application No.：
200610018930.5, it is entitled：Response type suppresses depressor；Although the patent of above-mentioned two earlier applications overcomes biography
The deficiency of system drawing method, the basic skills also as emergency responses of nuclear accident field nuclear pollution emergency disposal, but using
, there is problems with Cheng Zhong：（1）What cloth was spilt is solid-liquid mixed liquor, after need to being uniformly mixed during implementation, filling to implement
Diffusion control and compacting pre-treatment job could be implemented, the preparatory period is long, and labor intensity is big, for the time-bounded difference of emergency rating；
（2）Solid-liquid mixed liquor stability is poor, and easily lump blocking pipeline, requires high to distributing sprayer tool pipeline, shower nozzle；（3）Power-equipment is ground
Damage serious；（4）Film formation time is affected by environment big, especially the low environment of high humidity, temperature, the extension of film formation time indefinite duration,
Meet rain or cold can not film forming；Therefore the water base control compacting depressor and drawing method of a kind of radioactive contamination dust are proposed,
Basic demand as those skilled in the art.
