How to Improve the Dust Removal Efficiency of Bag Filter

Bag filter is the usage of a wide range of dust removal equipment and also is one of the more mature technology products. However, the current production technology of bag filter manufacturers is uneven. Due to immature technology, some manufacturers produce the bag filter dust removal efficiency cannot achieve satisfactory results. According to Zhengkuang mining machinery dust collector production experience for many years, about how to improve the dust removal efficiency, summed up the following points for your reference.

① Strengthen management, raise awareness. Dust collector is not the auxiliary system of production system. It is a main equipment in the production process circulation system. It directly affects the operation of the kiln, grinding, drying machines and other host production, quality. To ensure that the equipment system and dust collector synchronous operation rate and good rate. Some leadership only pay attention to the units of the kiln and grinding intact rate, but the dust whether can run well or not without attention, air leakage, lack of bags, auxiliary equipment damage is not included in the management, and sometimes casually remove, stop the dust collector. For the normal operation of the dust collector cannot bring the yield, quality fluctuations, there is no good analysis and understanding.

② Strengthen the dust collection system sealing. Dust collection system mainly include dust collector and dust collection system in the other equipment, such as rigid impeller under the feeder, import and export valves, transportation equipment and pipelines, inspection doors. Strengthen the cold smoke chamber inspection hole and the door seal, and it is best to use double doors, doors around the seal to use heat-resistant silicone rubber. Conveyor equipment should also strengthen the maintenance of sealing to reduce and eliminate air leakage phenomenon. Shell all connections must be continuous welding, are not allowed to have a leak, the phenomenon of openings (at the door hole and the Department of clearing the most vulnerable to air leakage).

③ Minimize the number of open and shut the dust collector and the number of checks. Dust collector is generally not abnormal or long outage, and do not open the inspection door maintenance. For each open time, dust collection system in the boot or during the maintenance period, the formation of the temperature dropped the condensation, seriously affects the life of the filter.

④ Strengthen the dust collector insulation. Many cement plant due to the insulation is not enough attention to the construction of poor quality, use for some time, a large area of insulation materials fall off, the rain falls into the insulation layer, resulting in poor insulation. The thickness of the insulation layer should be selected, according to the local temperature reasonable thickness, the outer surface of the steel plate to be selected and some better protective layer to extend the service life of insulation and thermal insulation effect.

There are many factors that affect dust collection efficiency, as long as we fully understand and master the design requirements and dust collector technical performance, scientific management and maintenance, will be able to maximize the efficiency of dust collection and play a dust filter itself role.
