Title: Method and device for concentrating rare gas
Inventor: NAKAMURA MATAJI
IPC: G21F9/02
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To downsize facilities for treating rare gases by effectively separating them from off-gases and concentrating them to reduce the volume of gases that need to be treated. SOLUTION: The air containing rare gas and the air free from the rare gas flow into the second adsorption tank 31 by way of the second pressurizing valve 46 and a pressure- equalized flow path 70 respectively to approximately equalize the pressures in adsorption tanks 30 and 31. Five seconds later, the first decompression valve 61 opens and the air rich in rare gas is sucked from the adsorption tank 30 into a recovery buffer tank 65. Meanwhile, the air containing rare gas flows into the second adsorption tank 31 by way of the pressurizing valve 46 and the internal pressure of the tank 31 gradually rises. The air containing rare gas and the air free from rare gas flow into the first adsorption tank 30 by way of the first pressurizing valve 45 and the pressure-equalized flow path 70 respectively to approximately equalize the pressures in the adsorption tanks 30 and 31.  Five seconds later, the second pressure reducing valve 62 opens and the air rich in rare gas is sucked from the adsorption tank 31 into the buffer tank 65. Meanwhile, the air containing rare gas continues flowing into the adsorption tank 30 by way of the pressurizing valve 45 and the internal pressure of the tank 30 gradually rises. By repeating such a cycle, the air rich in rare gas is mixed with the air containing rare gas and is fed to the adsorption tank 30 or 31 and the air free from rare gas is discharged to the outside of a system. As a result, the rare gas in the air containing rare gas circulates through the second pump 43, the adsorption tanks and the buffer tank 65, and the gas is gradually accumulated.
