[0002] In the production process of traditional sulfur monochloride, chlorine gas is usually introduced from the top of the reaction kettle. This method has several problems: first, the high-speed introduction of chlorine gas can cause the chlorine gas pipe to vibrate violently, and the chlorine gas pipe is prone to breakage due to fatigue and corrosion after a long time of operation, which not only affects the continuity of production, but also poses a safety hazard; second, since chlorine gas is introduced from the top, the material (such as sulfur) at the bottom of the reaction kettle can solidify due to temperature reduction during the reaction process, causing the discharge port to be blocked during discharge; finally, the catalyst (such as ferric trichloride) is prone to deposit at the bottom of the reaction kettle due to its high density under the action of gravity, and it cannot be fully stirred by the stirring device alone, resulting in uneven reaction, prolonged reaction time, and reduced production efficiency. At the same time, the catalyst sinking to the bottom can also cause local overheating or incomplete reaction, affecting the quality of the final product. Therefore, there is an urgent need for a chlorination reaction kettle design that can solve the above problems to improve production efficiency, ensure production safety, and improve product quality.
