1. Large volume, which is an effective way and development trend to increase production, reduce quality errors between mass production, and reduce product costs. Most of the reaction kettles used in dye production are below 6000L in China, and some are up to 30m³ in other industries; in foreign countries, there are 20,000-40,000L in the dye industry, while other industries can reach 120m³.
2. The agitator of the reaction kettle has been developed from a single agitator to a forced circulation with a double agitator or an external pump. In addition to being equipped with a stirrer, the development trend of the reaction kettle also makes the kettle body rotate along the horizontal line, thereby increasing the reaction speed.
3. Replace the cumbersome manual operation with production automation and continuity. If program control is adopted, it can not only ensure stable production, improve product quality, increase income, reduce manual labor, but also eliminate environmental pollution.
4. Reasonable utilization of heat energy, selection of optimum process operating conditions, enhancement of thermal insulation measures, improvement of heat transfer efficiency, reduction of heat loss to the limit, and full comprehensive utilization of waste heat or heat energy generated after reaction. The application of heat pipe technology will be the development trend of the reactor in the future.
