System for semicoke gasification preparation synthetic gas

The utility model relates to a system for semicoke gasification preparation synthetic gas. This system includes oxygen release reactor, splitter, gasification reaction ware, thick synthetic gas clarification plant, oxidation reactor, heat exchanger, steam accumulator, gas storage device and feeder. The oxygen carrier granule carries out the oxygen release reaction under the atmosphere of oxygen release reactor at vapor, generate to contain the gas mixture of oxygen and vapor and the oxygen carrier granule behind the oxygen release, and the oxygen carrier granule behind gas mixture and the oxygen release separates through the splitter, gas mixture and semicoke gasification reaction in the gasification reaction ware generate thick synthetic gas, vapor and dust, formation synthetic gas are got rid of through thick synthetic gas clarification plant to thick synthetic gas, oxygen carrier granule and oxygen containing gas oxidation reaction in oxidation reactor behind the oxygen release generate by the oxygen carri
