Ceramic liquid distributor has a rough and uneven appearance, with many pore sizes ranging from 6 to 10 millimeters. The product is bowl shaped, with ventilation holes spaced in the middle of the distributor and convection holes spaced around the ventilation holes. An overflow port is set at the upper end of the convection holes, and a flow blocking groove is set on the lower end face of the distributor at the peripheral position of the convection holes. The height of the overflow port shall not exceed one-third of the height of the convection hole. When the liquid flow rate is high, in order to ensure uniform distribution of gas-liquid convection in the convection hole and maintain a certain height of liquid, an overflow port is set at the upper end of the convection hole to ensure that uniform distribution of gas-liquid convection can always be maintained in the packed tower. When the liquid distributor is placed unevenly, a flow blocking groove is set on the lower end face of the distributor body around the convection hole to prevent liquid from flowing in the bottom surface of the distributor body.
The main specifications of ceramic distributors include: φ 500 φ 600 φ 700 φ 800 φ 900 φ 1000 φ 1100 φ 1200 φ 1300 φ 1400 φ 1500 (mm), etc

Due to the phenomenon of liquid flow in the packing layer of the tower equipment, there may be hook flow, deviation flow, and wall flow, resulting in amplification effect and end effect in the packing tower, which will reduce the separation efficiency. Therefore, liquid distributors are mostly installed in packed towers to evenly distribute liquid components across the entire tower section, prevent hooking, skewing, and wall flow phenomena, reduce the impact of amplification and end effects, and thus improve separation efficiency.
