In a preferred embodiment, the present invention provides a kind of boric acid crystallization remover, wherein the anion Surfactant is neopelex.
A second object of the present invention is to provide a kind of applications of boric acid crystallization remover, efficiently to remove light water reactor nuclear power The boric acid crystallization generated in standing.
In order to achieve this, the present invention provides a kind of boric acid crystallization removal as described above in the embodiment on basis Agent removes the application of boric acid crystallization in light water reactor.
In a preferred embodiment, the present invention provides boric acid crystallization remover as described above in light water reactor nuclear power The application of boric acid crystallization is removed in standing, wherein spraying the boric acid crystallization remover in the form of mist or foam in light-water Reactor of nuclear power plant boric acid crystallizes stained surface, while guaranteeing that boric acid crystallization is completely covered in the boric acid crystallization remover.
In a preferred embodiment, the present invention provides boric acid crystallization remover as described above in light water reactor nuclear power The application of boric acid crystallization is removed in standing, wherein injection is in light after the boric acid crystallization remover is packed into the pressurization watering can of inflation Water-water reactor nuclear power station boric acid crystallizes stained surface.
The application method of boric acid crystallization remover of the invention is: (1) using the pressurization watering can that can be inflated;(2) it sprays After pot pressurization, boric acid crystallization remover is sprayed in the form of mist or foam and crystallizes stained surface in boric acid, while guaranteeing boron Boric acid crystallization is completely covered in acid crystal remover;(3) boron crystallization has been dissolved with the erasing of common dirt removing cloth after reacting 1-10 minutes Boric acid crystallizes remover, repeats aforesaid operations when necessary or with the secondary wiping of demineralized water.
The beneficial effects of the present invention are, not only can be normal using boric acid crystallization remover of the invention and its application The lower boric acid crystallization quickly, in high-efficiency dissolution light water reactor of temperature, and it is applicable to various complex environments.Component in remover It is clear, without to the harmful halide ion of nuclear power system;Remover, can be safe and applicable in various metals and material table in alkalinity Face;Remover greatly reduces waste liquid yield with atomized soln or form of foam application.
The features of the present invention and effect are embodied in:
1, it quickly, efficiently can remove boron at normal temperature and crystallize spot;
2, the boric acid that remover is suitable for all related facilities of light water reactor, equipment and pipeline crystallizes removal;
3, since remover ingredient is relatively easy, reduce the introducing of impurity and harmful element;
