EXHAUST GAS SUPPLY AND DISCHARGE METHOD AND DEVICE TO REGENERATIVE COMBUSTION TYPE EXHAUST GAS PURIFIER

摘要

PPROBLEM TO BE SOLVED: To prevent the static-pressure fluctuation of a heat regenerative combustion type exhaust gas purifier for performing the combustion treatment of an exhaust gas containing a combustible toxic component even in the simultaneous "open" state of a supplying-side poppet damper and a discharging-side poppet damper, in an exhaust gas supply and discharge method to the regenerative combustion type exhaust gas purifier for supplying and discharging the exhaust gas by opening and closing a plurality of poppet dampers in interlocking with the exhaust gas purifier. PSOLUTION: At least two or more poppet dampers of a plurality of poppet dampers 7-10 provided on the exhaust gas supplying side and discharging side of the regenerative combustion type exhaust gas purifier 1 are substantially simultaneously opened, whereby part of the treated exhaust gas discharged from the discharging-side poppet damper is sent to the sucking side of a blower 5 arranged on the exhaust gas supplying side of the exhaust gas purifier 1.
