The utility model relates to a fixing device of a bracket shaped like the Chinese character ''jing'' and a U-shaped bolt for a heat exchange tube of a large aniline fluidized bed. The fixing device consists of the bracket shaped like the Chinese character ''jing'' and the U-shaped bolt. The heat exchange tube passes through the bracket shaped like the Chinese character ''jing'' and is fixedly arranged on the bracket shaped like the Chinese character ''jing'' through the U-shaped bolt. According to the fixing device of the bracket shaped like the Chinese character ''jing'' and the U-shaped bolt for the heat exchange tube of the large aniline fluidized bed provided by the utility model, the heat exchange tube is locked by the U-shaped bolt on a supporting piece, so that zero gap is realized and multi-point support is ensured, therefore, the vibration frequency of the heat exchange tube is changed fundamentally.
