The equipment that separates industrial dust from flue gas is called industrial dust collector or industrial dust removal equipment. The performance of an industrial dust collector is expressed by the amount of gas that can be handled, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life, and ease of operation and management of industrial dust collectors are important factors in considering their performance. Our common industrial dust collectors mainly include bag filter, industrial filter dust collector, electrostatic precipitator, and three kinds of dust removal equipments, which have their own advantages and disadvantages. With the stricter and stricter requirements for environmental protection requirements, gradually evolved a new type of electrostatic bag electrostatic precipitator. Today we will discuss the comprehensive comparison of the electrostatic bag dust collector and the bag filter.
1. Compared with bag filter, electrostatic precipitator of electrostatic precipitator is more than one electrostatic precipitator, but the increased electrostatic precipitator can not reduce the size of bag-removal dedusting, because the number of bags mainly depends on the amount of smoke and filtration. The wind speed, although higher filtration speeds can be used to reduce the filtration area, because the bag filter speed depends on the material itself, but not with the inlet concentration, and the number of bags is also very limited. In the combination of the two, electric bag composite dust removal is about 20% more than that of bag filter.
2, bag life is mainly determined by the material's resistance to chemical wear and physical wear, electrostatic dust bag electrostatic dust collection can reduce the physical wear of the bag, but the reduction in physical wear to the extent of the overall life expectancy still need to According to the argument, there is currently a point of view that within the range of acceptable physical wear of the bag material itself, the life of the filter bag depends mainly on chemical wear;
3. The operation resistance of the electrostatic dust collection bag can be lower than that of the bag filter, but larger than that of the electrostatic dust collection. If the original surplus of the induced draft fan is limited, the investment for replacing the induced draft fan cannot be saved. If the original induced draft fan has a certain margin, you can try to transform the induced draft fan to save investment.
4. As the draught fan of the old power plant generally adopts the constant power motor drag method, the energy conservation benefit of using the dynamic and low resistance characteristics of the electric bag compound dust removal operation needs to be realized through the energy saving transformation (such as frequency conversion).
5, need to increase the electrostatic part of the operation and maintenance personnel and costs.
