除尘布袋糊袋后,灰尘致密地覆盖在滤袋表面,使得滤料的有效过滤面积大幅减小,滤材的透气量急剧下降,运行阻力变得很高,使得引风机的负荷增加,造成能耗上升,严重的甚至会使引风机不堪重负而无法运转。同时,除尘布袋的压降居高不下使得在线清灰系统频繁清灰,不但需要消耗大量的压缩空气,而且会造成滤料的机械强度的严重损失,使用寿命大大缩短。

1结露性糊袋

一般情况下,布袋除尘器的运行温度要求必须高于酸露点温度25℃以上,对于布袋来讲运行比较安全。这主要就是为了避免结露的发生。当运行温度低于露点时就会结出液态水,液态水与粉尘混合并聚集在滤袋表面就会形成糊袋。

其次,脉冲清灰的压缩空气也是引起结露的可能原因之一。压缩空气温度一般远远低于除尘器运行温度,在脉冲瞬间,低温压缩空气会使滤袋上部的温度迅速降低,当低于露点温度时,就会导致该部位的滤袋外表面出现结露。

此外,除尘器的漏风率也是造成结露的可能因素。一般除尘器的漏风率在1%~2%左右。但随着运行时间的延长,漏风率会有所升高。如果是在冬季严寒的北方,问题就变得较大了。漏风率越高,对除尘器内的局部温度的影响越大,该泄露部位的滤袋囚结露而糊袋的风险越来越高。

1,严格控制运行温度,防止结露

要防止袋式除尘器滤袋结露糊袋,就必须保持处理气体温度高于其露点25℃~35℃。将除尘器用于处理高温、高湿气体时,应在入口处安装温度检测报警装置进行监控,并在壳体外加装岩棉等保温材料进行保温。


2,做好除尘器本体密封工作

除尘器必须严格密封,漏风率小于3%。在设备安装过程中,焊接质量至关重要。所有焊接必须按照相应规范和标准实施,焊接完成后采用荧光粉进行泄漏检查,漏气之处必须重新焊接。除尘器的检查门必须采用橡胶条加以密封,并经常检查更换。仔细检查各卸料器和法兰,做好密封。减少除尘器漏气量,可以有效保护滤袋,避免糊袋的发生,确保设备在较低阻力下平稳运行。


3,进行正确的开关机操作
