对顶部送风式差压预冷机温度场均匀性进行了试验。根据直观分析法进行了预冷效率、耗电量的试验,结果表明,影响预冷效率和耗电量的因素由大到小依次为风温、堆码高度和风速。分别测定了宽度方向温度均匀性、左右方向温度均匀性和上下方向温度均匀性,试验结果表明,温度均匀性都符合设计要求,能够达到均匀快速预冷的目的。 The uniformity of the temperature field of the top blower differential pressure precooler was tested. According to the direct analysis method, the precooling efficiency and power consumption were tested. The results showed that the factors influencing the precooling efficiency and power consumption were air temperature, stacking height and wind speed in descending order. The temperature uniformity in the width direction, temperature uniformity in the left and right direction, and temperature uniformity in the up and down direction were respectively measured. The experimental results show that the uniformity of the temperature meets the design requirements and achieves the goal of uniform and rapid precooling.
