Single reflection hypergravity device and process for continuous preparation of toluene diisocyanate

The invention belongs to the technical field of toluene diisocyanate production, in particular relates to a single reflection hypergravity device and process for continuous preparation of toluene diisocyanate, and solves the problems of poor reaction selectivity, decreased conversion rate and possible reaction device fault under large flow volume ratio differences of materials in the existing production process of toluene diisocyanate. The hypergravity device includes a cold reactor and a heat reactor; the cold reactor comprises a non-limitative impinging stream structure and a hypergravity structure, and the non-restrictive impinging stream structure comprises a main feeding pipe and a casing pipe in different diameters and baffle plates. The process is as below: flowing a phosgene inert solvent solution and a toluenediamine inert solvent solution into the non-restrictive impinging stream structure, then following into a rotation packing, then flowing into the heat reactor, and reacting to generate a TDI crude product. According to the invention, toluenediamine almost reacts completely, so s to prevent generation of urea materials, effectively avoid plugging of the pipeline and reactor, and improve the production efficiency of toluene diisocyanate.
