Abstract

The invention discloses a reforming reactor used in a vapor reforming hydrogen production device. The reforming reactor comprises a shell, wherein a flue gas input tube, a vapor input tube, a materialconveying tube and a reformed gas output tube are arranged on the shell; the shell is divided into a reforming zone and a heat accumulation zone; a plurality of reaction tubes are arranged inside thereforming zone; the flue gas input tube is communicated with the shell at reaction tube feeding ends; the reformed gas output tube is communicated with discharge ends of the reaction tubes and extends outside the shell; the heat accumulation zone is positioned on one side of reaction tube outlet ends; a plurality of material preheating tubes are arranged inside the heat accumulation zone; the material conveying tubes are communicated with the input ends of the material preheating tubes; the output ends of the material preheating tubes and the vapor input tube are both communicated with feeding ends of the reaction tubes; a flue gas output mechanism is arranged in the heat accumulation zone. The reforming reactor has the advantages that waste heat of a flue gas can be sufficiently utilized, the hydrogen production cost can be reduced, and the reaction speed and the conversion rate can be effectively increased.
