Do a good job in the control of dust accumulation and the selection of anti-static dust bag.
As an important component of the process system, the bag filter will often receive dusty gas from the pipeline and be derivatized into a dust layer during the application process. When the dust reaches a concentration between 20-6000g/m3, it will be In danger.
Therefore, in the design process, the ventilation capacity of the precipitator system should be further enhanced, and the dust in the dust should be removed in time to ensure that the dust concentration is below the dangerous range. At the same time, it is necessary to pay attention to the removal of the funnel dust. The dust produced by the common production dust will continue to accumulate heat, which is easy to produce dust spontaneous combustion.
In addition, since the dust does not exist in a strict state during the accumulation process, there is a circulating air, which creates conditions for the occurrence of dust explosion to some extent. Therefore, it has been proved by practice that the introduction of a double-layer pneumatic ash discharge valve can achieve the air leakage rate. The reduction can also effectively prevent the occurrence of dust spillage.
In the selection of anti-static dust bag, many coal dust, chemical dust, etc. will increase the probability of explosion accidents when encountering static electricity, so anti-static dust bag can choose stripe anti-static and blend anti-static products Type, the former mainly sets the conductive yarn of copper-infiltrated composite in the warp yarn of the needle felt base fabric. The latter mainly uses conductive fiber in the material. The specific selection can be combined with the actual production conditions to make the anti-static dust bag effect fully Play. And ensure that the dust collector has a reliable grounding.
