The 350,kg/h straw pyrolysis system with the moving bed is taken as research object,a new method is proposed for the pyrolysis of mixed gaseous heat-carring medium based on the heat storage of self-generated gas. Many experiments are conducted in order to solve such technical problems as non-uniformity of working medium,bed material bypass and perforation,high ratio of powders carried by gaseous products,and high column resistance.The optimization methods of pyrolysis tower structure are proposed,which are improving the ratio of height to diameter and installing a bridge broken cone.The practical results of pilot system show that the system can operate continuously under stable conditions with high-quality products.Results have a significance supporting value for solving technical difficulties of straw pyrolysis technology and play an important role in accelerating the commercialization of straw pyrolysis process. |
