导流板。WSA湿法硫酸工艺——电容器顶管板（涂层顶管板，WSA冷凝器——第1机组顶管板）

The top tubular plate of the capacitor of wet acid production technology is processed as a whole plate in monolithic design, and the holes are formed by precision CNC machining, which ensures an accurate and uniform distance between the hole centers and ensures the accuracy of subsequent assembly. After successful inspection, the metal parts are subjected to internal cladding, while special materials from DuPont (USA) or Daikin (Japan) are used for the starting materials of the cladding. After plating, the surface undergoes heat treatment, which further improves the operating properties. This top tube board is designed for long-term use at temperatures up to 120°C, with the maximum allowable temperature being 150°C. It is suitable for contact with a mixture of flue gases SO3 and sulfuric acid with a concentration of 0 to 98%.
