Description

Technical Field

[0001] The invention relates to the technical field of nuclear energy safety and environmental protection, in particular to a portable marine radioactive nuclide rapid collection and enrichment device. Background Art

[0002] A nuclear power plant is a facility that uses nuclear energy to generate electricity. Its core is to generate electricity through heat energy produced by nuclear fission reactions. Currently, a large number of nuclear power plants have been built in coastal areas. Due to the vast area of ​​the ocean, it has unique waves, tides and ocean currents. Therefore, once radioactive nuclides enter the ocean, the contaminated area will spread and transfer on a large scale with the movement of the ocean. When a leakage accident occurs in a coastal nuclear power plant, a large amount of radioactive nuclides such as I, Cs, Sr, etc. are directly discharged into the seawater through wastewater, or the radioactive aerosols contained in the exhaust gas are deposited on the sea surface and enter the ocean. Therefore, it is necessary to use radioactive nuclide collection and enrichment equipment to collect the nuclides in the seawater.

[0003] There are still some problems in the use of existing marine radioactive nuclide rapid collection and enrichment devices. During the adsorption process using the adsorption component, seawater needs to be transported to the inside of the adsorption component for adsorption. In order to prevent impurities in the seawater from affecting the collection, a filter is used to prevent foreign matter from entering. However, foreign matter will also clog the filter and affect the collection, and the pH value of seawater will also affect the adsorption efficiency of the adsorption component. Therefore, technical personnel in this field provide a portable marine radioactive nuclide rapid collection and enrichment device to solve the problems raised in the above background technology.
