A device for preparing fulvic acid by using subcritical water pyrolysis to treat straw
By designing a reciprocating motion structure and a sealed feeding structure, the problems of uneven stirring and disruption of the high-temperature and high-pressure environment during feeding in the subcritical water pyrolysis device were solved. This achieved uniform contact between straw and subcritical water and continuous and stable feeding, thereby improving the preparation efficiency of fulvic acid and the stability of the equipment.

Abstract
本发明公开了一种利用亚临界水热裂解处理秸秆制备黄腐酸的装置，属于生物质液化设备技术领域，包括反应釜釜体、加热线圈、上封盖、上搅拌叶片、下刮板、密封送料结构、上下往复运动结构，所述上下往复运动结构在反应釜釜体内卡合转动，所述密封送料结构卡合安装在上封盖的顶壁上。为解决现有技术中搅拌方式单一导致秸秆与亚临界水接触不均匀、易产生局部过热和结焦，以及加料时需开盖或泄压破坏高温高压反应环境的缺陷，本发明提供一种利用亚临界水热裂解处理秸秆制备黄腐酸的装置，有效解决了目前市场上亚临界水热裂解装置搅拌死角多、反应不均匀、无法在密闭状态下连续稳定加料的问题。
