EXHAUST GAS TREATMENT APPARATUS

摘要

Provided is an exhaust gas treatment apparatus which can reduce construction cost and enhance maintenance by simplifying a structure of the exhaust gas treatment apparatus. The exhaust gas treatment apparatus has a sealed vessel 21. The sealed vessel 21 is vertically partitioned into two spaces by a partition 22. A portion of the sealed vessel 21 lower than the partition 22 is an absorbing liquid storage portion 24, and a portion of the sealed vessel 21 upper than the partition 22 is an exhaust gas introducing portion 26. The partition 22 is provided with a large number of sparger pipes 29 so that the sparger pipes 29 reach inside an absorbing liquid stored in the absorbing liquid storage portion 24. The partition 22 is provided with a single gas riser 30 in communication with a space upper than the absorbing liquid in the absorbing liquid storage portion 24. An upper end of the gas riser 30 passes through a top plate portion 32 of the sealed vessel 21 and protrudes upward. Introduced exhaust gas is ejected into the absorbing liquid from the exhaust gas introducing portion 26 through the sparger pipes 29 and then derived outside the sealed vessel 21 from the gas riser 30.
