Disclosed is an adsorption tower of dry gas treatment equipment wherein toxic substances in waste gas are adsorbed to an adsorbent effectively to the maximum while avoiding complication of constitution. The adsorption tower (100) has a supply port (101) of a granular adsorbent (B), a section (102) for bringing the adsorbent (B) and waste gas (A) into contact with each other, and a delivery section (103) and a discharge section (104) of the adsorbent (B) which adsorbed the waste gas (A). A waste gas supply passage (108) and a waste gas discharge passage (109) are provided in the contact section (102) wherein the supply passage (108) has one end side communicating with a hood section (106), the other end side extending in the contact section (102) in the horizontal direction, and an end portion closed for a hood section (107). The discharge passage (109) has one end side communicating with the hood section (107), the other end side extending in the contact section (102) in the horizontal direction, and an end portion closed for a hood section (106). The supply passage (108) and the discharge passage (109) are formed by arranging saddle members (110) of identical structure. The saddle member (110) is a reverse V-shaped member arranged to penetrate the contact section (102) in the horizontal direction and forms an internal gas flow passage (111) by preventing permeation of the adsorbent (B) flowing downward at an upper part. |
