摘要

在引风机叶片上加装射流喷嘴装置吹扫引风机叶片的积灰。应用Fluent软件模拟引风机不同喷嘴进口风速下引风机叶片非工作面上的静压分布。结果表明

引风机变负荷运行时

叶片非工作面低压区压力若达到满负荷时的压力值即可防止叶片积灰。通过比较引风机各负荷不同工况下的静压分布

可获得各负荷对应的最佳喷嘴进口风速和风量

在保持吹扫效果的同时降低了能耗。

Abstract

A jet nozzle device was installed on the induced draft fan(IDF)to blowing the ash deposited on the blade.The Fluent software was used to simulate the static pressure distribution on non-working surface of the IDF blades with different inlet air speeds.The results showed that

during the variable-load operation of IDF

when the pressure at low pressure area of non-working surface of the blade reached the full load pressure

the ash deposition would be prevented.By comparison of static pressure distribution under different-load conditions

the corresponding optimal inlet air speed and flow of the nozzle were obtained.The ash blowing effect was kept and the energy consumption was reduced.
