Description

A kind of water base control remover of radioactive contamination dust recycling and removing method
Technical field
Remover is controlled the present invention relates to one kind, is eliminated more particularly, to a kind of water base control of radioactive contamination dust recycling Agent and removing 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 elimination, dividing into open area and the class of building dense area two by sedimentation, suitably carrying out extensive work The decanting zone of process control and cancel job 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 that consequence eliminates action, and the implementation of the fixed anti-suspension measure of 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 Method means of fixation and the removing of precipitum are varied, and these technologies and method are not with eliminating object to all controls 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 will With the mode of highest benefit lowest costs, the factor such as the net loss evil from reduction general impacts to greatest extent and to personnel reaches Optimal population equilibrium.
The nuclear polluted dust particles diffusion migration control of open area ground, which eliminates generally to use, shows radioactive dust particle The method of field transfer, the method traditionally used has following several：（1）Water jetting；（2）Shoveling principle；（3）Turn over method；Traditional core The drawbacks of contamination control removing method, is mainly reflected in the following aspects：（1）Top layer migration control effect does not reach emergent place Requirement is put, it is otherwise costly；（2）Script solid fraction nuclear pollution thing is converted into good fluidity, disposes more difficult waste water, nuclear pollution Fixation, migration control it is extremely difficult；（3）Easily cause secondary or secondary pollution；（4）Nuclear pollution eliminates not thorough；（5）Amount of waste Greatly, transport, store or disposal costs height；（6）Operating efficiency is low, and the disposal cycle is long, and personnel's radioactive dose is big, it is necessary to bulky spoke Penetrate safeguard；These drawbacks greatly limit these conventional methods and eliminate answering for field in open area ground emergency flight control With；Application No.：201410060571.0, it is entitled：Exfoliated pressed detergent；And Application No.： 200610018930.5, it is entitled：Response type inhabitation detergent；Although the patent of above-mentioned two earlier applications overcomes biography The deficiency of system decontamination 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 decontamination 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.
