Core structure of static mixing reactor and static mixing reactor

The utility model relates to a core structure of a static mixing reactor and the static mixing reactor, the core structure comprises a central cylinder (1), and the axial direction of the central cylinder (1) is recorded as the vertical direction; the heat exchange pipes (2) are spirally coiled on the periphery of the central cylinder (1) from inside to outside to form coil pipes (20), and the number of the coil pipes (20) is at least two and the coil pipes (20) are arranged up and down; the first connecting pipe (3) is used for feeding and discharging a heat-conducting medium and is communicated with the inner end part (21) of each coil pipe (20); the second connecting pipe (4) is used for feeding and discharging a heat-conducting medium and is communicated with the outer end part (22) of each coil pipe (20); the inner end parts (21) of the coil pipes (20) are arranged at intervals along the circumferential direction of the central cylinder (1); and/or the outer end parts (22) of the coil pipes (20) are arra
