| Ceramic strip arches are used as support structures for bottom packing in dry absorption towers of concentrated sulphuric acid. The product has the advantages of better compatibility, lower cast, easier design and manufacture, shorter overhauling period and longer life time than cast iron ball arches. Their hole-opening rate is more than 60%. They have the properties of good anti-corrosion and acid-proof, good heat proof and stability, and uniform air distribution. Products in required sizes can be made according to the tower diameter. We offer construction direction for customers. |
