[0002] Anhydrous sodium sulfide is an important chemical raw material and is widely used in many fields. However, the traditional anhydrous sodium sulfide production equipment and process have some shortcomings, which limit the improvement of production efficiency and product quality: 1. The traditional production equipment often fails to achieve the desired effect when crushing and mixing raw materials such as mirabilite and coal powder. On the one hand, the design of the crushing device is not reasonable, resulting in uneven particle size of the raw materials, which may affect the speed and degree of the subsequent reduction reaction. On the other hand, the mixing process is not sufficient, and the raw materials cannot be uniformly mixed, which may cause inconsistent local reactions during the reaction process, reduce the production efficiency, and also may lead to unstable product quality; 2.

For example, the pipe diameter of the conveying pipeline does not match the output diameter of the pump, which may cause poor conveying, even block the pipeline, and affect the continuity of production. Moreover, the connection between the dissolving tank and the dryer is not reasonable, which may cause leakage and loss of the product during the transfer process, and reduce the utilization rate of raw materials and the yield of products.
