Double-bed water vapor gasification hydrogen production system for household garbage

The utility model discloses a double-bed water vapor gasification hydrogen production system for household garbage, which comprises a circulating fluidized bed combustion system for fully oxidizing and combusting garbage coke to generate hot sand and hot flue gas to supply heat to gasification, the fixed bed garbage gasification system is used for converting the household garbage into coke and hydrogen-rich synthesis gas; and the synthesis gas treatment system is used for cooling and purifying the synthesis gas, separating tar impurities and obtaining high-quality hydrogen-rich synthesis gas.According to the utility model, garbage is gasified under a reductive condition, and the gas production rate and the gas production quality are improved at the same time through a steam reforming reaction among water vapor, tar and coke, so that hydrogen-rich synthesis gas is obtained, and a garbage hydrogen production function is realized. 本实用新型公开了一种生活垃圾双床水蒸气气化的制氢系统，包括用于将垃圾焦炭充分氧化燃烧，产生热沙与热烟气，给气化供热的循环流化床燃烧系统；用于将生活垃圾转化为焦炭及富
