Adsorption tower device and air separation device equipped with adsorption tower device

摘要

PROBLEM TO BE SOLVED: To reduce the installation area of an adsorption tower device, simplify the piping work at the installation place, and reduce the installation cost even if the adsorption tower is piled on the upper part of the valve switching device, compared to the past. Providing equipment. An adsorption tower device (1) has a valve switching device (30) and at least two adsorption towers (10, 20) arranged above the valve switching device (30) and filled with a predetermined adsorbent. A first introduction connecting portion 15 provided from the tower bottom 11 toward the valve switching device 30, a first internal pipe 16 extending from the tower top 13 toward the tower bottom along the center in a cross-sectional view in the tower transverse direction, It has a first outlet connecting portion 162 which is located at one end portion 16 a of the one internal pipe 16 and which is provided from the tower bottom portion toward the valve switching device 30.
