Description

Technical Field

[0001] The utility model relates to an emergency treatment system for leakage of methyl chloroacetate raw material, belonging to the technical field of chemical production. Background Art

[0002] Methyl chloroacetate is an organic compound, a colorless transparent liquid, slightly soluble in water, and miscible in ethanol, ether, acetone, and benzene. It is mainly used as an organic synthesis intermediate for the preparation of the synthetic insecticide dimethoate, and can also be used as a solvent.

[0003] Prior art CN 207096777U discloses a gas leak emergency treatment system. The system is connected to a gas source and includes a control unit, a gas detection unit, an alarm unit, a remote monitoring unit, and a gas treatment unit. The gas detection unit, alarm unit, remote monitoring unit, and gas treatment unit are each connected to the control unit, which is in turn connected to the gas source. The gas treatment unit includes a pretreatment tank and a spray tower, which is connected to the control unit. The spray tower is provided with a packing layer and an absorption liquid layer. However, this treatment system can only handle gas leaks in fixed locations and cannot handle gas leaks in non-fixed areas, such as cylinders, storage tanks, and other leak points.
