<p>PROBLEM TO BE SOLVED: To lower a resistance in the gas flow passage of an absorption tower and at the same time, reduce a gypsum scaling part. SOLUTION: This structure of an in-tower circulation spray pipe comprises a support member for the circulation spray pipe 1 of an absorption liquid spray pipe for spraying an absorption liquid, extended by a specified length above and below the circulation spray pipe 1, along a pipe axial direction and also outwardly in the diametral direction of the pipe 1, and a reinforcing plate 2 formed integrally with the support member. The support member of the spray pipe 1 is removed and the occupancy area of the absorption liquid spray pipe in the flow passage cross section is reduced by increasing the strength of the spray pipe 1 itself.</p> |
