| 摘 要： | 全面地分析了除尘器的除尘效率测定误差产生原因，推导出在一定条件下除尘效率测定误差理论计算公式，经实例验证与理论符合。并得出在采样气体状态参数和环境条件一定时，除尘效率的测定误差主要取决于取样时间及流量。当取样时间在（１０～１５） ｍｉｎ 和流量（１０～１５）ｌ／ｍｉｎ时，除尘效率测定误差可控制在±６％ 左右

| Abstract: | The causes of deviation in measuring the collection efficiency of the dust precipitator were analyzed. A calculation formula for the deviation was established and verified under certain condition. Under a definite gas state parameter and environment condition,the measurement deviation was correlated with the sampling time and the flow rate. When sampling time was 10-15 min and sampling flow rate rate was 10-151/min,the measurement deviation was in the range of ±6%. |
