Dynamic hole jet mixed reactor and method for producing diphenyl methane series diamine and polyamine by using same

The invention discloses a dynamic hole jet mixed reactor. A plurality of first multi-orifice sprinklers (5) with material circulating runners (12) and second multi-orifice sprinklers (6) are arranged inside a mixed reaction tank (4) of the reactor; the plurality of multi-orifice sprinklers (5) and second multi-orifice sprinklers (6) are arranged coaxially with a transmission shaft (8); the second multi-orifice sprinklers (6) are fixed at the outer wall of an interlayer (7) of the mixed reaction tank (4) and communicated with the interlayer (7); the plurality of first multi-orifice sprinklers (5) are fixed on a first feeding pipe (1) and communicated with the first feeding pipe (1), and rotate under the drive of the first feeding pipe (1); the first multi-orifice sprinklers (5) and the second multi-orifice sprinklers (6) are arranged in a staggered manner or in parallel; and a second feeding pipe (2) is communicated with the second multi-orifice sprinklers (6) through the interlayer (7) of the mixed reaction t
