PROBLEM TO BE SOLVED: To perform exhaust gas treatment by most effectively using a heat storage body in a heat storage chamber. SOLUTION: A gas supply/discharge distribution device 6 having a rotor 9 constituting a gas supply chamber 12IN and a gas discharge chamber 12OUT both of which sandwich a purge chamber 12P in a vertical direction is formed at a bottom stage of a treatment column 2 having an exhaust gas treatment zone 3 formed at an upper stage and a heat storage chamber 5 formed at a middle stage, and the rotor 9 is provided with an opening disk 14 facing a bottom face side of the heat storage chamber 5 and having an outlet 14IN for blowing an exhaust gas to a gas feed zone 4P, a purge opening 14P for supplying a purge gas to a purge zone 4P and a suction opening 14OUT for sucking a cleaned gas from the exhaust zone 4OUT opened successively, and a seal system 17 for preventing the exhaust gas from leaking through a gap formed around a peripheral part is formed on the peripheral part of the opening disk 14. |
