[0002] Reactors play a crucial role in the production of 2-ethylanthraquinone. However, conventional reactors present several challenges. First, they lack a single method for introducing raw materials, preventing the number of inlet tubes used from being flexibly adjusted based on the type of raw materials being processed, and failing to effectively prevent leakage from unused inlet tubes.

[0003] Secondly, when it comes to mixing raw materials, traditional reactors often only stir in a single direction, resulting in low mixing uniformity and efficiency, which affects product quality and production efficiency. Furthermore, the raw materials are often not effectively preheated before entering the reactor, which means it takes a long time for the raw materials to reach the reaction temperature inside the reactor, reducing reaction efficiency.
