Abstract
The utility model discloses a process evaluation system for a multifunctional gas-solid fluidized bed, and the process evaluation system comprises a gas buffer tank and a steam generating furnace. Two paths of gas feeding materials enter a fluidized bed reactor to react with solid particle reactants through a gas heating furnace and a fixed bed reactor. After being cooled by a primary cooler, a gas product generated by the fluidized bed reactor enters a primary gas-liquid separator to realize gas-liquid separation. Liquid separated out by the primary gas-liquid separator is stored in a primary liquid storage tank and is weighed by a primary electronic weigher. Gas separated out by the primary gas-liquid separator enters a secondary cooler to be cooled to the room temperature and then enters a secondary gas-liquid separator to complete gas-liquid separation. Liquid separated out by the secondary gas-liquid separator is stored in a secondary liquid storage tank and is weighed by a secondary electronic weigher.
