[0002] In the petroleum processing industry, heat treatment is one of the key steps in crude oil refining. Traditional petroleum heating equipment typically uses fixed heating tubes or external jacket heating methods, which suffer from problems such as low heat transfer efficiency and uneven heating, easily leading to localized overheating or coking, affecting subsequent distillation results. Although existing stirring heating devices can improve heating uniformity, they generally have disadvantages such as complex structure, high energy consumption, and difficult maintenance. Utility Model Content
