REGENERATION COLUMN AND DRY APPARATUS FOR DISCHARGE GAS TREATMENT

摘要

A regeneration column which comprises: a regeneration column main body (11) having a long trunk; and desorbed-gas discharge paths (15) through which a desorbed gas is discharged. The main body (11) comprises: a heating part (26) which heats an adsorbent; a separation part (25) which separates a desorbable substance as a desorbed gas from the heated adsorbent; and a cooling part (27) which cools the adsorbent from which the desorbable substance has been desorbed by heating, the parts (26), (25), and (27) having been communicatively disposed in one direction and the heating part (26) and the cooling part (27) having approximately the same sectional outer diameter. The separation part (25) comprises an inner barrel part (30) and a flow velocity reduction part (31) which reduces the flow velocity of the desorbed gas. The desorbed-gas discharge paths (15) are apart from each other and connected to the downstream side of the flow velocity reduction part (31).
