Description

Technical Field

[0001] This utility model relates to the field of 2-chloropropionyl chloride processing, and more particularly to a 2-chloropropionyl chloride reactor. Background Technology

[0002] 2-Chloropropionyl chloride is an important organic chemical intermediate, a colorless or pale yellow liquid with a distinctly pungent odor at room temperature. Its synthesis and processing typically utilize 2-chloropropionyl chloride reactors. These reactors often employ a stirred tank structure, equipped with a highly efficient stirring system and a jacketed or coiled cooling system to maintain a suitable reaction temperature, thereby effectively controlling the reaction rate and suppressing side reactions.

[0003] In related technologies, the production and processing of 2-chloropropionyl chloride is mainly carried out inside the 2-chloropropionyl chloride reactor. Since 2-chloropropionyl chloride has certain corrosiveness and toxicity, the 2-chloropropionyl chloride reactor is usually made of stainless steel or lined with PTFE to resist the strong corrosiveness of chlorinating agents and intermediate products. In order to ensure the airtightness and safety of the reaction, the reactor is usually equipped with a sealing structure.

[0004] However, during the synthesis of 2-chloropropionyl chloride, a certain amount of harmful gases may be released during the reaction. The accumulation of these gases may cause the internal pressure of the 2-chloropropionyl chloride reactor to increase, thereby increasing the risk of gas leakage. Once harmful gases leak, they will not only pollute the operating environment, but also pose a significant safety hazard.

[0005] Therefore, it is necessary to provide a 2-chloropropionyl chloride reactor to solve the above-mentioned technical problems. Utility Model Content

It should be noted that the cross-section of the bottom annular cover 501 and the upper annular cover 502 are both L-shaped. By closing the bottom annular cover 501 and the upper annular cover 502, they can be spliced ​​into a U-shape, which can cover the connection between the first flange plate 104 and the second flange plate 105, thereby improving the leak-proof effect at the connection between the first flange plate 104 and the second flange plate 105.

The gas leak-proof cover 5 is installed outside the reaction tank 1 and connected to the purification chamber 4 through the second exhaust pipe 6. When the pressure inside the reaction tank 1 increases as the reaction proceeds, the pressure relief valve 2 is used to relieve the pressure in the reaction tank 1, and the discharged gas is transported into the purification chamber 4 through the first exhaust pipe 3. When a gas leak occurs in the reaction tank 1, the leaked gas is transported into the purification chamber 4 through the second exhaust pipe 6 through the gas leak-proof cover 5.
