[0002] Acetyl chloride is a colorless or slightly yellow liquid with strong irritation. In the production process of acetyl chloride, a large amount of chlorine is required. The existing acetyl chloride reactor has a slow reaction rate, and the internal chlorine is unevenly dispersed during the reaction. After the chlorine is introduced, the dispersion is poor and it quickly overflows inside the liquid and cannot be absorbed by the liquid to participate in the reaction. In addition, waste gas is generated after the reaction, which needs to be treated to meet the standards before it can be discharged into the atmosphere.

[0003] The Chinese utility model patent with announcement number CN217796116U, a chloroacetyl chloride reactor with an exhaust structure, includes a reactor body, a fan box and an electric controller are arranged on one side of the reactor body, a guide pipe is arranged on one side of the reactor body, branch pipes are evenly arranged on one side of the guide pipe, an exhaust fan is arranged in the fan box, an external exhaust pipe is connected to one side of the exhaust fan, an internal exhaust pipe is connected to the other side of the exhaust fan, an air supply pipe is connected to the top of the exhaust fan, electric control valves are arranged at the mouths of the external exhaust pipe, the internal exhaust pipe and the air supply pipe, the air supply pipe is connected to the top of the guide pipe, and the internal exhaust pipe is connected to the bottom of the guide pipe. The device allows chlorine to be fully dispersed and reacted, improves production efficiency, accelerates reaction speed, improves the purity of the reaction product, improves the utilization rate of chlorine, and quickly and timely discharges the waste gas remaining in the reactor body to prevent the waste gas from polluting the body, which is convenient for next use and improves the service life of the reactor.

[0005] 1. The above device transports chlorine from the air supply pipe to the guide pipe through the exhaust fan, and then discharges it through multiple branch pipes connected to the guide pipe. The chlorine enters the reactor body and mixes with the raw materials. However, the guide pipe in the above device is arranged on a side wall of the reactor body, and the multiple branch pipes are distributed longitudinally along the guide pipe. Therefore, when the chlorine is discharged from the branch pipe, it will mix with the raw materials close to one side thereof, float up in the raw materials and be discharged from the raw materials, and cannot be quickly mixed into the entire raw materials, resulting in uneven mixing.

[0006] 2. When the above device is in use, since the branch pipe is horizontally arranged inside the reactor body, the raw materials in the reactor body may flow into the guide pipe along the branch pipe, and then flow into the exhaust fan along the guide pipe, causing damage to the exhaust fan, thereby affecting the actual use of the above device.
