Compared with Raschig rings, this packing has the characteristics of large production capacity, strong resistance, and high operating flexibility. Under normal circumstances, the processing can be 50%-100% larger than Raschig rings under the same pressure drop. The drop is 50%-70% smaller than the Raschig ring, and the tower height is also reduced. The use of the Pall ring can be about 20%-40% of the packing volume compared to the Raschig link.
Pall ring packing has the advantages of large flux, small resistance, high separation efficiency and large operating flexibility. Under the same pressure reduction, the processing capacity can be more than 50% larger than that of Raschig ring. At the same throughput, the pressure reduction can be reduced by half, and the mass transfer efficiency can be increased by about 20%.

Scope of application:
Suitable for carbon dioxide degassing tower, ozone contact reaction tower, etc. as contact and other reaction towers.

The main difference between it and Raschig ring packing is that there is a rectangular window hole on the side wall, and the window blade of the window hole is bent into the center of the ring. Due to the hole in the ring wall, the distribution performance of gas and liquid is better than that of Raschig ring. Great improvement is obtained, especially the inner surface area of u200bu200bthe ring can be fully utilized. Pall ring packing is a new type of packing, which is developed to improve some of the main shortcomings of Raschig rings. Eight layers of rectangular small windows are opened on the wall of ordinary Raschig rings, and the small window blades overlap in the center of the ring. The upper and lower windows are overlapped with each other.
