Bag filter has a wide range of practicability
The bag filter has a wide range of practicability. It can remove the most harmful respirable dust effectively. Generally speaking, large spikelet dust does not constitute a hazard to human body, nor is it the object of dust removal. The dedusting efficiency of the bag type dedusting equipment is over 99.9%, and the discharge concentration is below 20mg / m3, which is inferior to that of the electric precipitator and the wet precipitator. The size (filtering area) of the cloth dust collector is only related to the flow rate, and the dust efficiency is independent of the specific resistance of the dust. It's very harmful. For the micro dust below SOM, the dry electrostatic precipitator with high efficiency of dust removal can only remove 20%, but after passing the bag type dust removal equipment, the dust removal efficiency reaches 95%. For the dust particles with particle size less than 1mg, the bag type dust remover also has high efficiency of grading dust removal. Most of the harmful heavy metal particles are attached to the ash below 2 Shao in, so it is more effective to reduce the heavy metal pollution in the atmosphere by using the bag filter. The economic emission concentration of ESP is 100mg / m3, which is uneconomical if it is lower than this value, because the size of ESP is not only related to the flow, but also to the dedusting effect string. Moreover, the dedusting efficiency is very sensitive to the specific resistance of dust and the moisture and sulfur trioxide in the gas. Once there is a change, it often causes great fluctuation.
