Pall Ring Packing

Pall ring packing is a new type of packing, is aimed at some of the main shortcomings of the Lacy ring to improve and appeared, is in the wall of the ordinary Lacy ring open eight layers of small rectangular windows, small window leaves in the center of the ring overlap, the upper and lower layers of the window position of the mutual interlocking and become. The main difference between it and the Lacy ring packing is in the side wall open rectangular window holes, window holes in the window leaves bent into the ring center, due to the ring wall openings make the gas, liquid distribution performance compared to the Lacy ring to get a greater improvement, especially the inner surface area of the ring to be able to make full use of.

Pall ring Packing Material:

Ball ring packing is divided into three kinds of materials: ceramic, metal, plastic and so on. Metal materials: 304, 316, 316L, carbon steel, 201, 410 and so on. Plastic materials: PP, RPP, CPVC, PVDF, PVC, PTFE, FEP, PFA and so on. Among the plastic pall ring packing is generally divided into three shapes: meter-shaped, #-shaped, +-shaped, and other shaped pall ring.

Pall ring Packing Application:

Plastic pall ring packing is especially suitable for petroleum, chemical, chlor-alkali, gas, environmental protection and other industries in the low and medium temperature (60-150 degrees) distillation, absorption and scrubbing towers and carbon dioxide degassing tower, ozone contact reaction tower as a contact packing and other reaction towers.

Ceramic pall ring packing is suitable for carbon dioxide degassing tower acid mist purification tower, ozone contact reaction tower, etc. as contact packing and other reaction towers.

Metal pall ring Packing Application:Vacuum distillation columns, processing of heat-sensitive, easy to decompose, easy to polymerize, easy to carbonize materials.

Pall ring due to the ring wall openings, greatly improving the utilization rate of the ring space and the inner surface of the ring, airflow resistance is small, the liquid distribution is uniform. It has the advantages of large flux, small resistance, high separation efficiency and large operating flexibility, etc. In the same buck, the handling capacity can be more than 50% larger than that of Rasi ring. Compared with the Lacy ring, this packing has a large production capacity, strong resistance, operational flexibility and other characteristics, in general the same pressure drop when dealing with can be larger than the Lacy ring 50% -100%, the same treatment pressure drop than the Lacy ring is smaller than 50% -70%, pall ring gas flux can be increased by more than 50%, the efficiency of the mass transfer equipment to improve the efficiency of about 30%. pall ring is a kind of packing with wide application.

The parameters of the Ball ring packing vary according to the material.
