产品简介
1. Product description Pall ring is a new kind radom packing ring, developed based on Rasching ring, with equal diameter and height. Pall ring structure can improve distribution of liquid and gas,fully using the inside surface which helps the gas and liquid flow freely through the windows of the ring. Pall ring can be classified to ceramic, plastic and metallic pall ring by materials. 2. Technical specification 2.1. Ceramic Pall Ring Size (D×H×T) mm surface area m2/m3 Void space% Bulk density Kg/m3 No.elements per/m3 Packing factor m-1 Φ25 25×25×3 210 73 630 36000 540 Φ38 38×38×4 140 75 590 12000 332 Φ50 50×50×5 100 78 520 4900 210 Φ76 76×76×9 70 80 470 1500 137 Ceramic pall ring has excellent acid resistance and heat resistance. It can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. The ring can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc. 2.2.
