III-shaped hypergravity device and technology for continuous preparation of toluene diisocyanate

The invention belongs to the technical field of toluene diisocyanate production and discloses an III-shaped hypergravity device and technology for continuous preparation of toluene diisocyanate. The device and technology solves the problem that the existing toluene diisocyanate production technology has poor reaction selectivity and a low conversion rate because of large difference of a material volume flow ratio thereby causing reaction device fault. The hypergravity device comprises a cold reactor and a heat reactor. The cold reactor comprises an unlimited impinging stream structure and a hypergravity structure. The unlimited impinging stream structure comprises a main material feeding pipe, an auxiliary material feeding pipe I and an auxiliary material feeding pipe II. The technology comprises that a phosgene inert solution and a toluenediamine inert solution are collided by the unlimited impinging stream structure, and the mixture is fed into a rotating filler, then is fed into the heat reactor and undergoes a reaction to produce a toluene diisocyanate TDI crude product. The device and technology realize basically complete toluene diisocyanate reaction, prevent urea substance generation, effectively prevent pipe and reactor blocking and improve toluene diisocyanate production efficiency.
