布袋除尘器是一种干式除尘装置,适用于捕集细小、干燥非纤维性粉尘。滤袋采用纺织的滤布或非纺织的毡制成,利用纤维织物的过滤作用对含尘气体进行过滤,当含尘气体进入布袋除尘器,颗粒大、比重大的粉尘,由于重力的作用沉降下来 ,落入灰斗,含有较细小粉尘的气体在通过滤料时,粉尘被阻留,使气体得到净化。今天,绿然小编和大家聊聊布袋除尘器定期维护及保养的相关知识。
布袋除尘器定期维护及保养
1、 凡遇除尘器临时停用时,各加热装置应继续保持工作。
 
2、 每班打开布袋清灰系统气包底部的球阀一次,以卸放气包内的压缩空气产生的冷凝水。
 
3、 定期检查布袋清灰系统中各个脉冲阀的动作情况,出现不动作的要及时处理。
 
4、 定期清洗提升阀气路三联件的过滤器,并定期给油雾器加入干净机油。
 
5、 定期检查提升阀动作情况。
 
6、 空气炮的检查及维护:
 
布袋除尘器定期检查
1月检:
 
1.1检查全部空气管道及连接处是否松动漏气。
 
1.2检查全部气动元件工作是否正常、灵活。
 
2、半年检:
 
2.1进行全面外观检查,空气炮有无结构损伤。
 
2.2关闭空气炮气源,释放炮体内气体,卸掉放水塞,排出内部全部积水,然后再把放水塞原处拧紧。
 
2.3检查空气炮的吊挂、支撑装置的焊接处,固定是否有损坏,螺栓是否有松动等不正常现象。
 
2.4正常操作时,如发现空气炮漏气,需清理或更换“0”型密封圈或活塞。此项工作应注意:首先关闭气源,停止供气,释放炮内气体,从炮筒上取下活塞进行清理,更换配件。无论是清理还是更换配件,只要活塞从炮筒中取出,都应更换新的“0”型密封圈。安装前活塞和密封圈都应加油润滑。
 
2.5检查炮头和炮体之间的法兰垫片,如损坏应更换,然后把全部零件安装牢固。
 
2.6检查全部接线,有无松动、磨损或断裂现象。
Cloth bag filter is a dry dust collector, which is suitable for collecting fine, dry non-fibrous dust. Filter bag used textile filter cloth or non textile mat is made, using the fabric filter effect of dust filters, gas when dusty gas into the bag dust catcher, large particles, major dust, due to the effect of gravity settling down, fall into the hopper, contains the fine dust of gas through the filter material, the dust were blocked, the purified gas. Today, green small make up and we talk about the periodic maintenance and maintenance of the cloth bag filter knowledge.
 
Regular maintenance of bag filter
 
1. When the dust collector is temporarily stopped, each heating device shall continue to work.
 
 
 
2. Open the ball valve at the bottom of air bag of cloth bag cleaning system once per shift to discharge condensed water generated by the compressed air in the air bag.
 
 
 
3. Check the operation of each pulse valve in the cloth bag ash cleaning system regularly, and deal with those that do not work in time.
 
 
 
4. Regularly clean the filter of the air way triplets of lifting valve, and regularly add clean oil to the oil mist.
 
 
 
5. Check the lifting valve operation regularly.
 
 
 
6. Inspection and maintenance of air cannon:
 
 
 
Periodic inspection of bag remover
 
January:
 
 
 
1.1 check whether all air pipes and joints are loose and leaking.
 
 
 
1.2 check whether all pneumatic components work normally and flexibly.
 
 
 
2. Semi-annual inspection:
 
 
 
2.1 conduct overall appearance inspection to check whether the air cannon has structural damage.
 
 
 
2.2 close the air source of the air gun, release the gas inside the gun, remove the drain plug, discharge all water inside, and then tighten the drain plug in place.
 
 
 
2.3 check the welding place of the hanging and supporting device of air cannon, and check whether the fixing is damaged or the bolts are loose or not.
 
 
 
2.4 during normal operation, if air leakage is found in the air cannon, the "0" sealing ring or piston shall be cleaned or replaced. Attention should be paid to: first, close the air source, stop the gas supply, release the gas inside the gun, remove the piston from the barrel for cleaning, and replace the accessories. When the piston is removed from the barrel, the new "0" seal ring should be replaced, either for cleaning or replacement of accessories. Piston and sealing ring should be lubricated before installation.
 
 
 
2.5 check the flange gaskets between the gun head and the gun body, replace them if damaged, and install all parts firmly.
 
 
 
2.6 check all wiring connections for looseness, wear or fracture.
