HEAT REGENERATING TYPE GAS TREATMENT DEVICE

PROBLEM TO BE SOLVED: To provide a high sealing function while simplifying device structure, in a heat regenerating type gas treatment device. SOLUTION: This heat regenerating type gas treatment device capable of passing a treated gas G and a treatment-finished gas G' in order, through a plurality of heat accumulation chambers 3 with one end side communicated with a combustion chamber 6, by communicating a supply port 33 for the treated gas formed on a change-over valve element 11 side opposedly with an exhaust port 35 for the treatment-finished gas, in order, with respect to supply and exhaust ports 16 formed in the distributor 10 side, in accompaniment to the rotation of the change-over valve element 11, is provided with an energizing means 44A for the change-over valve element for supporting the change-over valve element 11 in a state displaceable along an approaching and separating direction with respect to the distributor 10, and for pressing the change-over valve element 11 to the distributor 10 side in a non-acting state with respect to an air chamber device 13.
