Technical Field

[0001] This utility model relates to the field of vinylimidazolium copolymer production technology, specifically to a spray drying device for vinylimidazolium copolymer production. Background Technology

[0002] Vinyl imidazole copolymers are polymers containing vinyl imidazole units. This type of polymer is typically prepared via free radical polymerization and can be copolymerized with various monomers, such as acrylates and styrene, to adjust their physicochemical properties. Due to its unique chemical structure, vinyl imidazole endows these copolymers with good solubility, thermal stability, and compatibility with other materials, making them widely applicable in various fields. Spray drying is a technique for rapidly drying liquid materials into powder. It is particularly suitable for heat-sensitive materials because it can be operated at relatively low temperatures, thus avoiding damage to the material. For the production of vinyl imidazole copolymers, spray drying equipment is mainly used to convert the solution or suspension after the polymerization reaction into a solid powder form.

[0003] Based on the above, the following problems were found: During the use of the current spray drying equipment for vinyl imidazole copolymer production, the material is prone to deposit on the inner wall of the drying tower, which not only reduces the collection rate, but also makes the equipment difficult to clean and inconvenient to use.
