Radioactive matter containing waste gas treating installation

Abstract

Maintenance apparatuses for and improvements in a radioactive matter containing waste gas treating installation, which is capable of completely carrying out waste gas cleaning by means of ceramic filter element is disclosed. The installation is provided with at least one of the following three apparatuses or devices, i.e. A ceramic filter element exchange apparatus which is capable of preventing radioactive contamination caused by scattering of radioactive dust at the time of inspecting or exchanging the filter element and preventing an operator from being subjected to radiation internal exposure as well as rapidly exchanging a spent filter element for a new one by remote control; A ceramic filter element treating apparatus which can pulverize the spent filter element by mechanical power instead of human power in a short time so as to considerably reduce the spent ceramic filter element in volume and change it into a form which can easily be solidified; and A device having a sealed joint structure which is capable of securing the filter element to a support plate in a reliable and sealed manner by remote control.
