【摘要】 对 4种不同规格滤筒分别进行了清灰性能试验研究 ,试验结果表明滤筒夹角对滤筒清灰性能影响很大。当滤筒夹角小到一定程度时 ,在线清灰基本不起作用 ,必须采用离线清灰。试验还发现同一滤筒不同部位清灰效果不同 ,上部清灰效果最差 ,在此分析了其原因并提出改进措施。更多还原

【Abstract】 Four types of filter cartridges are studied on their cleaning performance.The results show that the included angle of a filter cartridge has great influence on its cleaning performance.If the included angle is smaller than a certain value,on-line cleaning is almost useless and off-line must be carried out.Moreover,it is found that the cleaning effect is different at different part of a filter cartridge; the worst effect takes place at the upper part.The reason is analyzed and measures are given to improve the effect.更多还原
