Plastic polyhedral hollow ball packing is a tower packing widely used in chemical, environmental protection, power and other industries.

1. Material and structure of plastic multi-sided hollow ball packing

Material: Plastic multi-sided hollow ball packing is usually made of polypropylene (PP) and other materials, and has the characteristics of high temperature resistance (usually less than 120 degrees), corrosion resistance, light weight, and high strength.

Structure: Two hemispheres are synthesized into a spherical shape, with several semi-span-shaped blades distributed on each hemisphere. These semi-span-shaped blades are arranged staggered on the two hemispheres to form a special three-dimensional structure. In addition, there is a reinforcement ring along the entire circumference in the middle of the ball. There are multiple ball flaps (such as twelve pieces) on the upper and lower sides of the ring, which are arranged radially along the central axis.

2. Characteristics and advantages of plastic polyhedral hollow ball packing

Large specific surface area: Multi-faceted hollow sphere packing has a large specific surface area, thereby increasing the contact area between the packing and gas and liquid, which is conducive to the gas-liquid mass transfer process.

High void ratio: The void between its blades and spheres provides sufficient circulation space for the gas-liquid mixture, so that the gas-liquid mixture can be fully contacted and mass transferred inside the packing.

Small resistance: The gas speed of polyhedral hollow ball packing is high, and due to its special structural design, the overall resistance is small and the operational elasticity is high.

High temperature and corrosion resistance: The polypropylene material makes it have good high temperature and corrosion resistance, and is suitable for a variety of harsh environments.

3. Application field of plastic polyhedral hollow ball packing

Environmental protection field: polyhedral hollow ball packings are widely used in environmental protection equipment such as chlorine removal, oxygen removal, carbon dioxide removal, and sewage treatment and waste gas treatment.

Chemical field: used for filling various chemical equipment, such as cooling towers, purification towers, etc., as well as oil-water separation, seawater desalination, pure water preparation and other processes.

Power field: It is also widely used in sewage treatment, CO2 removal equipment, desulfurization purification towers and contact reaction towers in power plant water treatment.
