In an exhaust gas treatment apparatus provided with activated carbon fiber towers (5, 6), a cleaning operation of activated carbon fiber filters (5a, 6a) inside the activated carbon fiber towers (5, 6) is performed without stopping the exhaust gas purification operation. Make it possible. A cleaning device 15 is configured to clean activated carbon fiber filters 5a and 6a in any one of at least two activated carbon fiber towers 5 and 6 when the activated carbon fiber tower 5 ( While the supply of exhaust gas to 6) is stopped, exhaust gas can be supplied to any one of the remaining activated carbon fiber towers 6 (5) that is not the object of cleaning, and the activated carbon fiber tower 5 ( 6) The activated carbon fiber filter 5a (6a) in the inside is washed by introducing washing water into the inside.
