Product introduction of polyhedral hollow ball packing
The multi-faceted hollow ball packing belongs to random chemical packing, and the material is PP polypropylene, which is resistant to acid and alkali and corrosion. The shape of the polyhedral hollow sphere packing is composed of two hemispheres into a spherical shape, each hemisphere is composed of several semi-fan blades, and the upper and lower blades are arranged staggered from each other. The multi-faceted hollow ball packing has a large specific surface area, and is mainly used in waste gas purification PP alkali washing towers, carbon dioxide removers, desulfurization and environmental protection water treatment projects.
Features of Polyhedral Hollow Ball Packing
high gas velocity;
many leaves
small resistance;
The specific surface area is large, which can fully solve the gas-liquid exchange.
Geometric properties of polyhedral hollow sphere packing
specific surface area
The filler surface area of the filler layer per unit volume, expressed in AT; unit: m2/m3. The same filler, the smaller the size, the larger the specific surface area, the larger the gas-liquid mass transfer area provided.
Porosity
The void volume of the filler layer per unit volume, expressed as ε; the unit is m3/m3, or expressed as a percentage. The larger the porosity of the packing layer, the greater the gas-liquid passing ability and the smaller the gas flow resistance.
filler factor
Indicates the hydrodynamic performance of the filler, expressed in φ, and the unit is 1/m. Dry Filler Factor: when the filler is not wetted; reflects the geometric properties of the filler. Wet filler factor: After the filler is wetted by liquid; it reflects the hydrodynamic properties of the filler. The smaller the Ф value, the smaller the flow resistance. Packed column calculations use the wet packing factor under wet conditions.
Why use polyhedral hollow sphere packing
The main purpose of the multi-faceted hollow sphere packing is to provide a large enough area for the gas-liquid two-phase transmission, so that the gas-liquid two-phase flow is in complete contact, and the gas-liquid flow will not cause too much resistance. The waste gas treatment spray tower packing is the simplest equipment for gas absorption. In the spray tower, the liquid is in the dispersed phase and the gas is in the continuous phase. Generally, the gas and liquid are relatively small, which is suitable for the absorption process of rapid chemical reaction, while the multi-faceted hollow The selection of ball packing is the core of the spray tower. The choice of the multi-faceted hollow ball packing is directly related to the operation performance of the PP spray tower and the efficiency of exhaust gas purification.
How to clean the polyhedral hollow ball packing
In the spray tower, after a period of operation, a certain thickness of salt will condense on the surface of the multi-faceted hollow ball packing, and the color will turn yellow. This time, manual cleaning is required. Open the discharge port, discharge the multi-faceted hollow ball packing, and pour it into the cleaning bucket. Inside, it is cleaned with high pressure water gun, and after being rinsed, it is loaded from the inlet of the spray tower packing. Pay attention to wear protective glasses, masks, and anti-corrosion gloves when cleaning the multi-faceted hollow ball packing to avoid corrosion
