HEAT STORAGE TYPE GAS TREATING DEVICE, AND METHOD OF PURIFYING HEAT STORAGE MATERIAL LAYER IN THE SAME

PROBLEM TO BE SOLVED: To improve versatility and reliability of a heat storage type gas treating device. SOLUTION: In the heat storage type gas treating device, gas permeable heat storage material layers are arranged at a plurality of gas inlet/outlet parts 3 to a combustion chamber 6, and a gas supply/exhaust air duct to/from the combustion chamber 6 is provided with a switching means V for sequentially switching the heat storage material layer 4 allowing the passage of gas G to be treated, to the combustion chamber 6, and the heat storage material layer 4 allowing the passage of treated gas G' from the combustion chamber 6 in the form of allowing the gas G to be treated and fed to the combustion chamber 6 in a following stroke, to pass through the heat storage material layer 4 through which the treated gas of high temperature delivered from the combustion chamber 6, has passed in a preceding stroke, out of the heat storage material layers 4. A cooling means 5 is provided for cooling the treated gas G' at an air duct part leading to the switching means V from an outlet of the treated gas G' in each of the heat storage material layers 4 out of the gas supply/exhaust air duct, or at an inlet part of the treated gas G' of the switching means V.
