TECHNICAL FIELD

[0002] Butadiene as an important chemical raw material, in the production and storage process, polymerization is easy to occur, this not only will influence product quality, also possibly brings the safety hidden danger. In order to prevent butadiene polymerization, usually needs adding polymerization inhibitor in the production process, the traditional production device has certain limitation in structure and function, and the existing device often is difficult to realize the full, even stirring of raw materials in the reaction kettle. One-way stirring can cause raw materials mixing to be insufficient, influence reaction efficiency and product quality. This is because butadiene extraction polymerization inhibitor production needs the accurate mixing of multiple raw materials, and uneven stirring can make the reaction of some areas be incomplete, thereby reducing the performance of polymerization inhibitor, for the cleaning problem of reaction kettle inner wall, traditional device operation is more cumbersome. In the production process, the inner wall of reaction kettle will inevitably attach some residues, if not promptly and effectively cleaned, these residues can pollute the next batch production, influence product purity. Moreover, long-term uncleaned inner wall can also cause equipment corrosion and scaling, reduce the service life and production efficiency of equipment, and the filtering link also has the deficiency. When the existing production device filters reaction, the dismounting and installation of filter screen are often difficult, are not conducive to the quick replacement and cleaning filter screen. This can cause the poor filtering effect, and impurities enter the product, influence the quality of polymerization inhibitor. At the same time, the blockage of filter screen can also affect the continuity of production, increase production cost and maintenance time, therefore we propose a kind of butadiene extraction polymerization inhibitor production device to solve this problem.
