Prevent piercing through device and molecular sieve adsorption tower

The utility model discloses a prevent piercing through device and molecular sieve adsorption tower belongs to air separation plant technical field. It includes to prevent piercing through the device: baffle mechanism one end is connected with the net that packs with the interior wall connection of adsorption tower, the other end. The utility model discloses prevent piercing through device and molecular sieve adsorption tower can not form the clearance and results in partial air directly to get into the air separation column not through the adsorbent when the adsorbent takes place the trace and subsides, has effectively avoided the molecular sieve adsorption tower to be taken place by pervious circumstances. 本实用新型公开了种防穿透装置和分子筛吸附塔，属于空气分离设备技术领域。所述防穿透装置包括：挡板机构端与吸附塔内壁连接，另端与填料网连接。本实用新型防穿透装置和分子筛吸附塔当吸附剂发生微量沉降时，不会形成间隙而导致部分空气未经过吸附剂而直接进入空分塔，有效避免了分子筛吸附塔被穿透的情况发生。
