| 简介 |
A method of re-starting a temperature swing adsorbing (TSA) device, wherein when the TSR device is stopped when the temperature of purge gas flowing out of a first adsorption tower (5a) in a regenerative step reaches peak in the regenerative step or thereafter, the gate and the atmosphere releasing valve of the first adsorption tower (5a) in the regenerative step are closed, the gate of a second adsorption tower (5b) in an adsorption step is closed and the atmosphere releasing valve is opened to discharge gas in a counter current direction against a raw air flow in the adsorbing step. Then the atmosphere releasing valve is closed to pressurize the second adsorption tower (5b) with the raw air to a pressure required for the adsorption step immediately before the re-start. After the re-starting, the regenerative step of the first adsorption tower (5a) and the adsorption step of the second adsorption tower (5b) are continuously performed after the TSA device is stopped. |
