<p>PURPOSE:To minimize gas pressure loss in an absorption tower as much as possible and improve cleaning efficiency by setting nozzle headers provided with upward liquid jet nozzles between the lower section of a gas inlet duct and the upper section of liquid level. CONSTITUTION:Untreated gas A introduced from a gas inlet duct 2 into an absorption tower 3 is brought into contact with a liquid separated from upward liquid jet nozzles 6 of nozzle headers 5 between the bottom section of the gas inlet duct 2 and the upper section of liquid level of a storage tank 1 for the liquid in the lower section of the absorption tower 3. Then gas-liquid contact between the sprayed liquid from the nozzles 6 and the untreated gas A is performed, and the untreated gas A is cleaned and exhausted as a treated gas B out of a gas oulet 4 formed on the top of the absorption tower 3. The flow of the untreated gas A passing through spaces among the nozzle headers 5 and flowing to the upper section can be avoided by the arrangement.</p> |
