A regeneration tower including a regeneration tower main body having a long trunk, and desorbed gas discharge passages through which a desorbed gas is discharged. The regeneration tower main body is configured so that a heating unit that heats an adsorbent, a separation part that separates desorbable substances as a desorbed gas from the heated adsorbent, and a cooling unit that cools the adsorbent from which the desorbable substances have been desorbed by heating are communicatively disposed in one direction and the heating unit and the cooling unit have approximately the same sectional outer diameter.

1. A regeneration tower, which desorbs adsorbed substances from an adsorbent to which harmful substances in an exhaust-gas are adsorbed, the regeneration tower comprising: a regeneration tower main body having a long trunk and configured so that a heating unit heating the adsorbent, a separation part separating desorbable substances as a desorbed gas from the heated adsorbent, and a cooling unit cooling the adsorbent from which the desorbable substances have been desorbed by heating are communicatively disposed in one direction and the heating unit and the cooling unit have approximately the same sectional outer diameter; anddesorbed gas discharge passages through which the desorbed gas is discharged,wherein the separation part includes an inner barrel part and a flow velocity reduction part that reduces a flow velocity of the desorbed gas, andthe desorbed gas discharge passages are connected to a downstream side of the flow velocity reduction part. 2. The regeneration tower according to claim 1, wherein: the inner barrel part has approximately the same sectional outer diameter as the heating unit and the cooling unit;at least a part of the flow velocity reduction part has a sectional outer diameter that is gradually enlarged toward a downstream side of the desorbed gas so as to surround an outer circumference of the inner barrel part; andan opening causing the inner barrel part and the flow velocity reduction part to communicate with each other is disposed on an upstream side of the flow velocity reduction part. 3. The regeneration tower according to claim 1, wherein: the flow velocity reduction part includes a plurality of compartments that are partitioned in parallel toward the downstream side, and the neighboring compartments communicate with each other on the downstream side; andthe plurality of desorbed gas discharge passages are connected to downstream sides of some of the compartments. 4. The regeneration tower according to claim 1, wherein the flow velocity reduction part is enlarged in diameter relative to the inner barrel part so that the desorbed gas flowing through the flow velocity reduction part has a flow velocity of 100 mm/sec or less. 5. A dry exhaust-gas treating apparatus comprising: an adsorption tower configured to adsorb harmful substances in a exhaust-gas to an adsorbent;a regeneration tower main body having a long trunk and configured so that a heating unit heating the adsorbent, a separation part separating desorbable substances as a desorbed gas from the heated adsorbent, and a cooling unit cooling the adsorbent from which the desorbable substances have been desorbed by heating are communicatively disposed in one direction and the heating unit and the cooling unit have approximately the same sectional outer diameter; anddesorbed gas discharge passages through which the desorbed gas is discharged,wherein the separation part includes an inner barrel part and a flow velocity reduction part that reduces a flow velocity of the desorbed gas, andthe desorbed gas discharge passages are connected to a downstream side of the flow velocity reduction part.
