In the context of increasingly stringent environmental protection policies, the flue gas dedusting of boilers to reduce particulate emissions has become an inevitable choice for industrial enterprises.A set of scientific and reasonable transformation program needs to be comprehensively planned from various aspects.
Before remodeling, a comprehensive assessment of the current status of boiler operation.Detect the operating parameters of the existing dust removal equipment, such as dust removal efficiency, flue gas flow, particulate concentration, etc., to analyze the reasons why it can not meet the standards, while combining the latest local environmental emission standards, clear transformation goals.
Process selection is the key to transformation.For small and medium-sized boilers, if the original equipment for the cyclone dust collector, can be upgraded to a bag filter, the dust removal efficiency of up to 99% or more, can effectively filter fine particles; for large coal-fired boilers, electric bag composite dust collector is a better choice, combining the advantages of electrostatic precipitator and bag filter, not only to deal with the high concentration of flue gas, but also realize the high efficiency of dust removal.
In the renovation and implementation stage, a detailed construction plan is required.First, dismantle the old equipment, do a good job of site cleanup and safety protection; then install the new equipment, strictly control the precision of equipment installation and the sealing of the connection of various components; and finally debugging, adjusting the parameters of the equipment through trial operation to ensure stable operation.
After the transformation is completed, it is equally important to establish a perfect monitoring and maintenance system.Regular monitoring of the dust removal equipment operating data, timely detection of potential problems; at the same time, routine maintenance and regular maintenance of the equipment, to extend the service life of the equipment, to ensure long-term stable operation, to achieve efficient dust removal of the boiler flue gas and environmental protection standards.
