AI Technical Summary

Technical Problem

The overall filtration volume of existing nuclear island radioactive waste filters is small, the filtration effect is poor, and the filtering filter element is not renewable, resulting in an increase in filtration cost.

Method used

A renewable filtration device for radioactive waste liquid in the nuclear island three-waste system was designed. Multiple sets of filters were distributed into multiple layers by installing brackets. Each set of filters was equipped with multiple filter balls and a removable filter element. Multiple pipe filtration and activated carbon filter balls were used for filtering, and the filter element and filter balls were regenerated through an annular vibrator.

Benefits of technology

It improves the filter volume and filtering effect of the filter, extends the service life of the filter device, reduces the frequency of replacing the filter element, and reduces the filter cost.

Abstract

The present invention provides a nuclear island three-waste system radioactive waste liquid renewable filtration apparatus, and relates to the technical field of nuclear power plant three-waste treatment, and the nuclear island three-waste system radioactive waste liquid renewable filtration apparatus comprises: a mounting bracket fixedly mounted in a reactor primary loop of a nuclear island radioactive water treatment system; the multiple groups of filters are distributed in multiple layers in the height direction of the mounting bracket, and a plurality of filters are arranged in each group; the water inlet pipes are communicated with the water inlet ends of the multiple groups of filters one by one, and the water inlet pipes are used for inputting wastewater into the multiple groups of filters; the water outlet pipes are communicated with the water outlet ends of the plurality of groups of filters one by one, and the water outlet pipes are used for outputting purified water purified in the plurality of groups of filters; when the multiple groups of filters are used for filtering, the waste liquid can be subjected to multi-pipeline filtering, and the filtering amount of the waste liquid is increased through multi-pipeline filtering. The problems that an existing water filter is small in overall filtering amount, poor in filtering effect, non-renewable in filtering element and the like are solved.
