  布袋除尘器的运转可分为试运转与日常运转。起首,进行试运转时,必需对系统的单一部件进行反省,然后作顺应性运转,并要作局部功能实验。在日常运转中,仍应进行需要的反省,特殊是对布袋除尘器的功能的反省。要留意主机设备负荷的转变会对除尘器功能发生的影响。在机械开动之后,应亲密留意布袋除尘器的任务情况,做好有关记载。
  在新的布袋除尘器试运转时,应特殊留意反省下列各点:
  1.风机的扭转偏向、转速、轴承振动和温度。

  2.处置风量和各测试点压力与温度能否与设计相符。
  3.滤袋的装置状况,在运用后能否有失落袋、松口、磨损等状况发作,投运后可目测烟囱的排放状况来判别。
  4.要留意袋室结露状况能否存在,排灰系统能否疏通。避免梗塞和侵蚀发作,积灰严峻时会影响主机的出产。

  5.清灰周期及清灰工夫的调整,这项任务是左右捕尘功能和运转情况的主要要素。清灰工夫过长,将使附着粉尘层被清落失落,成为滤袋走漏和破损的缘由。假如清灰工夫过短,除尘布袋滤袋上的粉尘尚未清落失落,就恢复过滤功课,将使阻力很快地恢复并逐步增高起来,最终影响其运用结果。

  两次清灰工夫距离称清灰周期,普通但愿清灰周期尽能够的长一些,使除尘器能在经济的阻力前提下运转。因而,必需对粉尘性质、含尘浓度等进行稳重地研讨,并依据分歧的清灰办法来决议清灰周期和工夫,除尘布袋并在试运转中进行调整到达较佳的清灰参数。
  在开端运转的工夫,经常会呈现一些事前意料不到状况,例如,呈现异常的温度、压力、水分等将给新安装形成损害。
  气体温度的急剧转变,会惹起风机轴的变形,形成不服衡形态,运转就会发作振动。一旦中止运转,温度急剧下降,再从新起动时就又会发生振动。最好依据气体温度来选用分歧类型的风机。
  除尘设备试运转的黑白,直接影响其能否能投入正常运转,如处置欠妥,布袋除尘器很能够会很快落空功效,因而,做好除尘设备的试运转必需细心和稳重。www.bschuchenqi.cn

在新的布袋除尘器试运行时,应特别注意检查下列各点:
1.风机的旋转方向、转速、轴承振动和温度。
2.处理风量和各测试点压力与温度是否与设计相符。
3.滤袋的安装情况,在使用后是否有掉袋、松口、磨损等情况发生,投运后可目测烟囱的排放情况来判断。
4.要注意袋室结露情况是否存在,排灰系统是否畅通。防止堵塞和腐蚀发生,积灰严重时会影响主机的生产。
5.清灰周期及清灰时间的调整,这项工作是左右捕尘性能和运转状况的重要因素。
必须对粉尘性质、含尘浓度等进行慎重地研究,并根据不同的清灰方法来决定清灰周期和时间,并在试运转中进行调整达到较佳的清灰参数。
