Description

This application discloses a drive control device and control method for an absorption tower, and more specifically, an absorption tower and a drive control method thereof that control fluid supply paths to multiple beds according to the adsorption values of each section. Ammonia is one of the substances that cause foul odors and can be generated not only in livestock barns but also in composting facilities that use chemical fertilizers and synthetic fibers, as well as in factories and sewage treatment plants. Conventionally, an absorption tower was driven to adsorb and remove ammonia. When the adsorption level exceeded a certain level, reducing the removal efficiency of the absorption tower, the system was controlled to desorb the ammonia and maintain a state where it could be adsorbed again. However, because the section at the front of the absorption tower adsorbs the fluid with the highest ammonia concentration, and the section at the back adsorbs the fluid with the lowest ammonia concentration, there was a significant difference in the adsorption efficiency or consumption rate of the adsorbent between the front and back sections. In particular, the adsorbent in the front section was consumed rapidly, and its adsorption/desorption cycle was shorter compared to other sections, resulting in a shorter lifespan and replacement cycle.
