Description

Technical Field

[0001] The utility model relates to the technical field of falling film absorption towers, in particular to a falling film absorption tower used for the production of pyraclostrobin. Background Art

[0002] Pyraclostrobin is a methoxyacrylate fungicide that inhibits mitochondrial respiration and eventually causes cell death. It has protective, therapeutic, and leaf osmotic conduction effects. A large amount of waste gas will be generated during the production of pyraclostrobin. If the waste gas is directly discharged, it will pollute the surrounding environment. Therefore, a falling film absorption tower for pyraclostrobin production is needed to absorb the waste gas.

[0003] At present, the falling film absorption tower used for the production of pyraclostrobin generally discharges liquid into the interior of the pipeline, cools the liquid inside the pipeline by a coolant, and forms a film on the inner wall of the pipeline, and discharges the waste gas generated during the production of pyraclostrobin into the pipeline, so that it contacts and is absorbed by the absorption film on the inner wall of the pipeline, thereby completing the treatment of the waste gas generated during the production of pyraclostrobin. However, at present, when the liquid is discharged into the interior of the pipeline, the liquid is usually discharged directly to the baffle at the top of the pipeline, and then flows into the interior of the pipeline by the weight of the liquid itself, which leads to uneven weight of the liquid inside the pipeline, and poor film formation inside individual pipelines, thereby reducing the absorption efficiency.
