The utility model provides a material distributor group of a multistage cold shock type fixed bed reactor. The device comprises a liquid-phase pipe, a gas-phase pipe and a plurality of combined nozzles, the combined nozzle is provided with a liquid-phase feeding channel communicated with the liquid-phase pipe and a gas-phase feeding channel communicated with the gas-phase pipe, the liquid-phase feeding channel and the gas-phase feeding channel are used for spraying out liquid-phase materials in the liquid-phase pipe and gas-phase materials in the gas-phase pipe in a combined mode, and a plurality of spiral winding pipes are distributed on the liquid-phase pipe at intervals and formed by spirally winding straight pipes; a plurality of nozzle holes are formed in the gas phase pipe in the length direction of the gas phase pipe, and the combined nozzles are arranged at the positions, corresponding to the nozzle holes, in the gas phase pipe so that materials sprayed out of the combined nozzles can be discharged through the nozzle holes. The multi-stage cold shock type fixed bed reactor material distributor group provided by the utility model can efficiently realize full atomization anduniform distribution of materials, accurately control the temperature of a catalyst bed layer, and ensure the yield of a target product and long-period stable operation of a catalyst.
