[0001] The utility model belongs to the field of azobisisobutyronitrile preparation industry, and specifically relates to a drying device for azobisisobutyronitrile processing. Background Art

[0002] Azobisisobutyronitrile (AIBN) is an organic compound, which is a white crystal or crystalline powder, insoluble in water, but soluble in organic solvents such as methanol, ethanol, ether, acetone, petroleum ether and aniline. Azobisisobutyronitrile is mainly used as a foaming agent for rubber, plastic, etc., and a polymerization initiator. After its processing is completed, it needs to be dried to remove residual moisture, ensure the purity of the product and meet the requirements of subsequent processing. In the prior art, the air flow distribution on the inner wall of the drying equipment may be uneven, and azobisisobutyronitrile may accumulate in the drying equipment, resulting in uneven drying degree. When the temperature of the drying equipment is too high, it is inconvenient to quickly cool the drying equipment, which leads to decomposition of azobisisobutyronitrile, thereby causing waste of materials.
