Claims

[Claims for Utility Model Registration] (1) In a reaction tower in which the flow rate of fluid in the tower is lower than the flow rate of fluid at the inlet or outlet, there is a A porous resistance plate whose cross-sectional area gradually decreases toward Characteristic reaction tower. (2) In a reaction tower where the flow rate of fluid inside the tower is lower than the flow rate of fluid at the inlet or outlet, at least one of the inlet and outlet has a stepped section in the middle, and the flow direction toward the inside of the reaction tower is low. 1. A reaction column characterized in that a cylindrical body with porous holes that shrinks as the cylindrical body is provided, and a middle stage portion and a small-area top portion of the cylindrical body are constructed with a closing plate.
