For the selection of structured fillers, we need to comprehensively consider factors such as production capacity, efficiency, operational flexibility, cost, and pressure reduction, as well as the corrosiveness of the materials. The following basic factors need to be considered:

1. The material used for filling should first be determined based on the corrosiveness and operating temperature of the processed material.

2. The size of the packing: There is a slight difference in the ratio of the tower diameter to the outer diameter of the packing, and we cannot predict its performance below this value.

3. The passing capacity of the packing: The passing capacity of the packing is the efficiency of the empty tower gas velocity packing at the liquid flooding point. The factors affecting the efficiency are very complex, and it is more reliable to design according to the measured values.

4. Pressure drop of packing: The power consumption of the packing tower mainly depends on the total pressure drop of the entire tower in the gas phase.

5. The properties of structured fillers: There are many types of structured fillers, some of which focus on the arrangement of gas-liquid flow channels to make the gas-liquid distribution as uniform as possible.

6. Some focus on expanding the contact surface.

7. Some consider reducing resistance as much as possible, resulting in various parallel plate membrane packed towers.

Regular fillers include many things, such as metal fillers, plastic fillers, Lacy rings, wreaths, etc. How can the Lacy rings in regular fillers be properly maintained?

Rasi ring is an early developed loose packing material with a height and outer diameter equal to each other. It was invented by German chemist Friedrich Rashg in 1914, and also marked the scientific trajectory of the development of tower fillers. However, in practical applications, phenomena such as "wall flow, channel flow" often occur

The sound of the normal bearing rotation of the Rasi Ring cooling tower should be clear, continuous, and uniform. If the sound is intermittent and the card indicates that there may be a defect in the bearing, further inspection is needed. If the fault occurs, the damaged gear should be replaced in a timely manner to avoid the cooling tower reducer from not functioning properly. Lashi Ring can be used in industries such as chemical, metallurgical, and gas oxygen production for drying towers, absorption towers, washing towers, and towers.
