In industrial production processes, dust pollution is a common environmental issue. Dust collection equipment, as the core equipment for controlling dust emissions and ensuring production safety and environmental quality, its scientific design and selection directly determine the dust removal efficiency, operational stability and economic performance. The physical and chemical properties of dust itself are the key factors influencing the design and selection of dust removal equipment. Dusts with different characteristics have significant differences in the requirements for dust removal principles, equipment structures and operational parameters. This article mainly introduces several characteristics of dust and corresponding measures for your reference.
Cartridge dust collectors are generally suitable for handling medium-concentration dust. Excessively high dust concentrations (such as sawdust from wood processing) may cause filter cartridge clogging, reducing dust collection efficiency and even damaging the equipment.
Solution: When handling high-concentration dust, add cyclone dust collector before the dust collector to reduce the dust concentration entering the cartridge dust collector.
Cartridge dust collectors can handle a wide range of dust particle sizes, from micrometers to millimeters.
Solution: For extremely fine or ultrafine dust (such as nano-sized dust), industrial dust collector require special filter media and filtration technology to improve dust collection efficiency.
The composition of dust also affects the selection of industrial dust collector. Factors include whether the dust is corrosive, flammable, or explosive.
Solution: Solution: For corrosive dust, dust collector needs to be corrosion-resistant; For flammable and explosive dust, dust collector needs to have explosion-proof measures. Equipping the dust collection equipment with explosion-proof motors, fans, flameless explosion vents, and fire dampers ensures safe operation.
Highly adhesive dust easily forms a solid dust layer on the filter cartridge surface, increasing cleaning difficulty and reducing dust collection efficiency. In extreme cases, adhesive dust may completely clog the filter cartridge, causing the dust collection equipment to fail.
Solution: Use a drier cleaning air source for jet cleaning to improve the cleaning effect. At the same time, optimize the cleaning system parameters, such as increasing the cleaning frequency and adjusting the jet pressure. Pre-filtration equipment can also be installed before the cartridge dust collecotr to reduce the concentration and adhesion of dust entering the equipment.
Therefore, when selecting dust collection equipment, a comprehensive consideration of the specific characteristics of the dust is necessary to ensure the normal operation of the equipment.
