Spiral flow type suspension bed reaction device

The invention discloses a spiral flow type suspension bed reaction device. The spiral flow type suspension bed reaction device comprises a spiral flow generator and a suspension bed reactor; an outletof the spiral flow generator is connected with an inlet of the suspension bed reactor; the spiral flow generator consists of a shell and a spiral structure which is arranged on the inner wall of theshell; the axial length of the spiral structure is equal to the axial length of the shell. According to the spiral flow type suspension bed reaction device, through the spiral flow generator, a material is fed into the cone bottom of the reactor in a double-spiral rotating manner under the action of the spiral structure; the material stirs reaction materials in the cone bottom while ascending, sothat the materials in the reactor are mixed uniformly; therefore, the heat and mass transfer effect of the reactor is effectively reinforced; the performance of the reactor is improved; moreover, thesuspension bed reactor does not have any internal components internally, and is simple in structure and convenient to maintain.
