摘要
运用流体力学知识,结合固定式沸腾冷却床的特点,提出了流化速度、床层压降、功率等工作参数的计算方法;分析了型砂大小、密度、粒度分布、床层高度等因素对工作参数的影响规律,在此基础上得出了沸腾床无法流化的原因和风压、风速之间的关系,并通过调整型砂参数得以解决。
Combining with the characteristics of stationary fluidized bed, a method was put forward by using the knowledge of fluid mechanics to calculate the working parameters, such as fluidized velocity, bed pressure drop, power, etc. The factors of sand such as size, density, size distribution, bed height, etc. on the influence of working parameters were analyzed. On the basis of the analysis above, the relationship between air pressure, air speed and the reason why stationary fluidized bed can＇t be fluidized was proposed, the problem was meanwhile solved by adjusting sand parameters.
