Claims

[Claims for Utility Model Registration] 1. A closed container having a space at the top and filled with a filler;
An inlet pipe whose tip is embedded in the filling material from outside the airtight container and introduces the gas to be treated, a wrapper tube connected to the tip of the inlet tube, and a wrapper tube with one end inserted into the wrapper tube and the other end. a bypass pipe connected to one end of a filling pipe arranged outside the sealed container; an outlet pipe that discharges gas led out from the space of the sealed container and communicates with the other end of the filling pipe; A dry gas supply parop interposed with a first valve for supplying dry air into the space, a second valve interposed in the outlet pipe, and a differential pressure gauge for measuring the pressure in the inlet pipe and the outlet pipe, The signal from this differential pressure gauge causes the first
A prefilter for radioactive gaseous waste treatment, characterized in that it comprises a signal system for operating the valve i and the second valve. 2.Registered utility model characterized in that the filling tube is filled with a filling material divided into cassettes. A prefilter for radioactive gaseous waste treatment according to claim 1. ′
