[0002] Ethylene dichloride is an organic compound. Ethylene dichloride is a colorless or light yellow transparent liquid that is insoluble in water. It is a colorless liquid with a chloroform-like odor at room temperature. It is toxic and potentially carcinogenic. It is mainly used as an intermediate in the production of vinyl chloride. It is often used as a solvent in synthesis and can be added to leaded gasoline to increase the octane number. It is also used as a solvent for wax, fat, rubber, etc. and a grain pesticide.

[0003] In order to cope with the changes in the domestic and foreign markets of 25,000 tons of ethylene dichloride and chloroethane per year, complete industrial transformation and upgrading, and gradually shift the industrial product structure from low-end products to mid-to-high-end products, the high-end market demand is surging, and the market demand for 25,000 tons of ethylene dichloride and chloroethane per year is rising, and supply is in short supply. The low-temperature chlorination method reacts below the boiling point of ethylene dichloride, and the reaction heat is removed by cooling water in the reactor's external cooler. The crude ethylene dichloride product is extracted from the liquid phase, and low-temperature direct chlorination is conducive to the production of higher-purity ethylene dichloride and can inhibit the occurrence of side reactions.

[0004] In the existing ethylene dichloride reaction system, when cleaning the feed mechanism, the cleaning liquid easily flows into the reactor. Generally, the staff has to dismantle the feed mechanism to clean it separately, which wastes a lot of manpower and increases labor costs.

[0005] Therefore, the existing ethylene dichloride reaction system cannot meet the needs in actual use, so there is an urgent need for improved technology to solve the above problems. Utility Model Content
