除尘器冒烟和冒灰现像属于严重损坏现象，应立即停机检修，下面净化铝材配件 http://www.jnjkjh.com/ 小编介绍一下冒灰和冒烟原因和处理办法
Dust collector smoke and ash is now a serious phenomenon, should be immediately shut down for maintenance, cleaning aluminum parts below the small series to introduce the cause and process of smoke and ash
原因：布袋除尘器出风口的冒烟尘情况有两种，一种是连续冒烟尘，即由于除尘滤袋破损严重，滤袋绑扎不牢脱落，或者布袋除尘器上下吊口不严密，上吊口与花板、花板与花板之间的连接不严密而造成的漏尘。另一种是瞬间冒烟尘，此种情况是除尘滤袋虽破损，但不甚严重，在布袋除尘器喷吹时出现瞬间冒烟尘。
Reasons: bag precipitator outlet of smoke dust condition has two, a is continuous take smoke, is due to severe damage to the dust filter bag, bag, lashing unstable off, or the cloth sack dust remover hanging mouth is not tight, hanging mouth and flower plate, flowers between the board and the board is not connected to the strict density caused by the leakage of dust. Another a kind of is instantly take smoke, this is dust filter bag, though damaged, but not very serious, when blowing bag type dust remover spray appear instantly take smoke.
因为当大部分除尘滤袋损坏时，应进行全部更换，更换除尘布袋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。
Because when most of the dust filter bag damage should replace all, replaced with dust bag deduster stops working. At that time, will be cleared off the grey controller, open the top of manhole door, can remove the bag, demolition, the first bag cage out. Then the cloth bag upper coil molded into the concave, up out of the bag type dust collector installed new bag before, will take on a plate hole of a dust clean.
查找布袋除尘器冒烟尘的原因时，可根据出风口冒烟尘时与电磁脉冲阀，脉冲控制仪动作时所对应的位数来判断是哪排除尘滤袋漏尘。上揭盖布袋除尘器亦可用手电筒从上箱体观察孔查出漏尘的滤袋；或打开上揭盖后再开脉冲控制仪，在喷吹过程中发现从哪个文氏管冒烟尘，就是那个除尘滤袋漏尘。然后，根据出现的问题进行处理。因为当大部分除尘滤袋损坏时，应进行全部更换，更换除尘布袋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。
Find the cloth bag dust remover to run a smoke, according to a tuyere soot and electromagnetic pulse valve, pulse control instrument action corresponding to the digits to determine which row dust filter bag dust leakage. To uncover the cover cloth bag dust remover also flashlight can be used from the box on the observation hole check out the leakage of dust filter bag; or open exposing cover the reopen after the pulse control instrument, in the blowing process found from which the venturi tube take smoke is the dust filter bag dust leakage. Then, according to the problem of emergence. Because when most of the dust filter bag damage should replace all, replaced with dust bag deduster stops working. At that time, will be cleared off the grey controller, open the top of manhole door, can remove the bag, demolition, the first bag cage out. Then the cloth bag upper coil molded into the concave, up out of the bag type dust collector installed new bag before, will take on a plate hole of a dust clean.
布袋除尘器更换除尘滤袋时，要检查分析其破损原因。影响除尘滤袋寿命的因素有粉尘的性质，气流的分布，除尘骨架的加工质量等。如因滤袋框架焊接不牢，在程使用过程中开焊，将除尘滤袋剌破，应及时焊好，并将除尘骨架毛刺焊渣磨平打光，或换新的除尘骨架。滤袋骨架通常是用直径4毫米的钢丝焊接而成的。常用的焊接方法有两种，一种是用点焊机点焊，另一种是用氧-乙炔焊接。采用前一种方法，生产效率高，表面光滑，不易产生毛刺，变形小。除尘器不能使用破损的除尘布袋进行工作，否则会加速除尘器的报废。当个别除尘布袋发生小面积破损时，为了节省开支，建议可以用旧的布袋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。采用后一种方法，生产效率低，表面粗糙，易变形。此外，还有的采用塑料框架，但这种框架不适于高温下使用。在喷吹过程中，由于滤袋每清扫一次，将与除尘框架外表面摩擦一次，因此除尘滤袋使用到一定时间后，虽未损坏，但其内表面与除尘框架接触部位已有磨损，再装时可根据磨损痕迹将原来的部位错开，以避免在原继续磨损，这样可延长除尘滤袋的使用寿命。
Bag filter dust bag replacement, to check the damage reason analysis. The nature of factors affecting the life of the dust bag dust, air distribution, dust skeleton processing quality. Such as due to the filter bag frame welding rickety, in process used in the process of welding, dust filter bag to cut, should be timely welding, and the dust skeleton burr welding slag grinding polishing, or change a new dust collection skeleton. The filter bag frame is usually with a diameter of 4 mm steel wire and welded. There are two kinds of welding methods, one is the use of spot welding spot welding, the other is the use of oxygen - acetylene welding. Using the former method, the production efficiency is high, the surface is smooth, not easy to produce burr, deformation is small. Dust remover can not use the damaged dust bag to work, otherwise it will accelerate the removal of dust collector. When the individual dust bag damaged area is small, in order to save money, it is recommended can be worn bag or the same material new cloth will break the filled in the hole using, fill hole method is the use of silicone rubber blend materials bonding, as long as the adhesive temperature and chemical properties and technological conditions adapt to. After the use of a method, the production efficiency is low, the surface roughness, easy deformation. In addition, there is the use of plastic frame, but this framework is not suitable for high temperature use. In blowing process, the filter every cleaning time, and the outer surface of the dust removal frame friction time, so dust filter bag used to a certain time, although not damaged, but the inner surface and the dust removal frame contact parts of the existing wear, can re installed according to the wear traces will open the original Ministry of dislocation, in order to avoid in the original to wear, which can prolong the service life of the filter bag dust.
安装布袋除尘器滤袋骨架时，对上揭盖脉冲除尘器要注意把多孔板上的积灰清除干净，以防接口与多孔板间不严密造成漏气，影响净化效率；喷吹管孔要对准文氏管中心，以保证喷吹效果。对侧开门除尘器要注意上下吊口松紧得当，以防下吊口脱落和拧坏螺纹。
Installation of bag deduster filter bag skeleton of on uncovering pulse dust catcher should pay attention to the porous plate on the ash cleaning clean to anti interface and the porous plate between the imprecision caused by leakage on the purification efficiency; blowing hole to align the venturi tube center, in order to guarantee the blowing effect. On the side door dust collector should pay attention to the upper and lower hanging mouth elastic properly, in case of hanging mouth off and screw bad thread.
除尘布袋拆卸安装时要注意不要与布袋除尘器金属棱角碰撞，以防暗伤。
Dust bag removing installation should pay attention not to bag type dust collector and metal edges to prevent collision, injury.
布袋除尘器冒烟尘的原因重点所在：
Reasons for the dust removal of the bag filter:
所以说一般情况下，布袋除尘器在使用中突然出现冒烟尘的现象，我们要及时停止除尘器的运行，马上进行停机检修。冒烟尘的主要原因之一就是破袋引起的。除尘滤袋是逐渐磨损的，引起磨损的主要原因是粉尘的磨削力，高温引起的布袋变质和化学物质的腐蚀，当粉尘的磨削力很强时，除尘布袋底部磨损最严重，系统容量的增加引起过滤速度增高也能加速磨损。
So the general situation, the use of bag filter in the case of the sudden emergence of smoke, we want to stop the operation of the dust remover, and immediately stop maintenance. One of the main reasons for the smoke is caused by a broken bag. Dust filter bag is gradually wear, the main causes of the wear is the grinding force of the dust, corrosion caused by high temperature bag modification and chemical substances, when the dust of the grinding force is very strong, the dust bag bottom wear the most serious, system capacity increase cause the filtration rate increased to accelerate the wear and tear.
