摘要

神华国华台山发电有限公司碎煤机室粉尘浓度超过100mg/m3

分析认为原因是上部物料掉落时产生的冲击气流将粉尘携带而出

并向周边空气中弥散所致。为此进行的改造措施有

设置阻尼装置

切断诱导风

在导料槽上设置无动力集尘单元降速吸尘。改造后

碎煤机室环境明显改善

粉尘浓度下降至4mg/m3以下。

Abstract

The dust concentration in crushing room of Guangdong Guohua Yudean Taishan Power Plant was over 100 mg/m3.The impact air flow formed by the upper material falling carried out the dusts and dispersed in the surrounding air was considered as the major reason.To solve this problem

several countermeasures were performed

such as setting the damping device and cutting off the induced air

installing nonpower dust collector unit on the belt conveyor chute to reduce the flow speed and collect the dusts.After the transformation

the dust concentration in the crushing room was below 4 mg/m3.
