Document Type and Number:
Japanese Patent JP7377689
Kind Code:
B2
Abstract:
To provide an air diffuser, radioactive gas treatment equipment, a radioactive material treatment system, and reactor equipment capable of achieving more stable operation.SOLUTION: The air diffuser includes: a header pipe that is arranged above the surface of the water in a tank where water is stored and extends in a horizontal direction for introducing steam from the outside of the tank; and a plurality of branch pipes which each communicate with the header pipe and extend downward, and the lower end of which is a steam outlet. With this configuration, since the header pipe is disposed above the water surface, the possibility that the header pipe may be cooled by the ambient water is reduced. Therefore a phenomenon called a condensation hammer caused by condensation of the steam in the header pipe can be avoided.SELECTED DRAWING: Figure 2
