    摘要:

    在一套高约18 m、内径为100 mm的提升管冷态实验装置上,根据容积法测量的颗粒循环量对HDLDG06粉体流量计的测量准确性进行了研究。结果表明,粉体流量计的测量准确性与提升管颗粒循环强度大小间的关系不大,而与提升管截面平均颗粒浓度大小有直接关系。在截面平均颗粒浓度小于6.9 kg/m3时,粉体流量计的测量准确性较好,在截面平均颗粒浓度大于6.9 kg/m3时,粉体流量计的测量准确性较差。根据相关实验数据,建立了HDLDG06粉体流量计在提升管中应用的校正关系式和适用条件。

    Abstract:

    On height of about 18 m and inner diameter of 100 mm of a cold riser experimental apparatus, the measurement accuracy of the HDLDG06 powder flowmeter was studied based on the particle circulation measured by volumetric meathod. The results show that the measurement accuracy of the flowmeter has little relationship with the particle circulation strength in the riser, while it has direct relationship with the crosssectional average concentration of the particle in the riser. When the sectional average concentration of the particle is less than 6.9 kg/m3, the powder flowmeter has quite a good measurement accuracy. While the sectional average concentration of the particle is more than 6.9 kg/m3, the powder flowmeter has quite a poor measurement accuracy.According to the experimental data, correction expression and its using condition isestablished for the HDLDG06 powder flowmeter applied to the riser.
