[0002] Packed tower, also known as packed tower, is a type of mass transfer equipment commonly used in chemical production. It is mainly composed of a cylindrical tower body and fillers (solids of various shapes, used to increase the area between the two-phase fluid and enhance the mass transfer between the two phases) stacked in the tower. It is used for absorption, distillation, extraction, etc. The gas-liquid distributor plays a key role in the distillation packed tower. It is mainly used to ensure that the liquid and gas are evenly distributed and effectively contacted in the tower, thereby improving the tower's operating efficiency and product quality. There are tubular gas-liquid distributors, orifice plate gas-liquid distributors, etc.
