The invention relates to a special-shaped helical pipeline reactor, which effectively solves the problems of low reaction rate, long time and too long required pipeline. According to the structure, a first temperature control probe is arranged inside an inner core pipeline; outer pipelines are rotatably arranged at intervals outside the inner core pipeline; a partition board is welded on the outer wall of the inner core pipeline; a helical channel is formed in the inner wall of an outer pipeline; the screw pitch of the channel is equal to that of the partition board; the screw angle of the channel is coincident with that of the partition board, so that a special-shaped helical pipeline channel structure is formed; two ends of the special-shaped helical channel are provided with a feed port pipe and a discharge port pipe; a cavity of the inner core pipeline is internally provided with a first heater; the outer side of a second heater on the outer wall of the outer pipeline is provided with an insulating layer; the feed port pipe is internally provided with a static mixing reactor; the second heater is provided with a second temperature control probe and a third temperature control probe; the three temperature control probes are connected with a controller through transmission lines. The special-shaped helical pipeline reactor is low in cost, good in effect and high in heat absorption efficiency, saves the energy, and is effectively used for the fields of petrochemical engineering, food, biochemistry, sugar refining and pharmacy.
