摘　　要：为了探索下降管式热解液化装置中生物质半焦和陶瓷球两种颗粒混合下落的运动规律,设计了下降管冷态模拟装置。通过冷态模拟,测试了陶瓷球和生物质半焦喂料器的稳定性和连续性,该装置能够实现两种颗粒的均匀、精确、连续喂料,能够满足实验所需要的两种颗粒的不同混合质量比的要求;PIV实验测试表明,该装置能够满足实验需要;陶瓷球和生物质半焦的混合,消除了PIV用圆管测试时由于光的反射和折射问题在管道轴线两侧所形成的许多亮白条纹,提高了数据的准确性。The cold state PIV analog equipment was designed to explore the movement law of the biomass chars and ceramic balls mix flows in the down flow reactor.By simulating the cold state,the stability and continuity of the equipment of ceramic ball and biomass char,the equipment implements even,precise and continuous down the mix of two particles were tested;it satisfied the requirements of the two particles different mass proportions in the experiment;by testing,the equipment can satisfy the experiment;many bright and white stripes formed by the light＇s reflection and refraction in two sides of the round tube axes in PIV were avoided by using the biomass char,and the veracity of data were greatly enhanced.
