仓顶除尘器的核心部件，主要有振动盘、除尘滤芯、电磁阀、防雨帽、控制仪，它们在仓顶除尘器使用中环环相扣，都起着重要的作用。
一般情况下，除尘滤芯是逐渐磨损的，引起磨损的主要原因是粉尘的磨削力，高温引起的除尘滤芯变质和化学物质的腐蚀，当粉尘的磨削力很强时，除尘滤芯底部磨损最严重，系统容量的增加引起过滤速度增高也能加速磨损。
仓顶除尘器不能使用破损的布袋进行工作，否则会加速除尘器的报废。当个别除尘滤芯发生小面积破损时，可以用旧的除尘滤芯或同样材料新滤布将破洞补上使用，补洞方法是使用有机硅橡胶混合料进行粘接，只要粘接剂的使用温度、化学性能与工艺状况相适应便可。
当大部分布袋损坏时，应进行全部更换，更换除尘滤芯最好在除尘器停止工作时进行，此时应将清灰控制器关闭，打开顶部的人孔门，便可拆卸布袋，拆卸时，先将袋笼取出，然后将布袋上口的弹簧圈捏成凹形，向上拉出除尘布袋，安装新布袋前，应将花板孔上的粉尘清理干净。
The core component of the warehouse roof dust, vibration plate, dust filter, solenoid valves, rain hat, controller, they are used in the warehouse roof dust interlocking plays an important role.
Under normal circumstances, the dust filter is gradually worn, the main cause of wear dust grinding force, caused by high temperature deterioration of the filter dust and corrosive chemicals, the grinding force is strong when the dust, the dust filter at the bottom of most wear serious system capacity caused by the increase in the filtration rate increase can accelerate wear.
Warehouse roof dust collector can not use a damaged bag to work, otherwise it will accelerate the retirement of the precipitator. When the the individual dust filter occurs when the breakage of a small area, with a the old dust filter or cloth of the same material can fill the hole, the hole filling method is to use a silicone rubber mixing an adhesive material, as long as the use temperature of the adhesive and chemical properties and state of the art can adapt.
When most of the damage to the bag, should be carried out to replace them all, replacement dust filter best precipitator stop working, cleaning controller should be shut down, open the top of the Manhole, you can remove the bag, demolition, first bag cage removed, and then the bag catchy coil shape into a concave up and out of the dust bag before installing a new bag, the tubesheet hole on the dust shall clean up. |
