Especially, the long low-pressure pulse bag filter bags, with cleaning ability, low pressure injection, filtered wind speed, low energy consumption, changing bags easy, simple maintenance, high degree of automation. The design of cold-rolled steel for Wuhan Iron and iron oxide scale dust features, economical and rational design of low pressure pulse bag filter for dust removal cold rolled strip steel. The design of the large amount of data on domestic and international, on the pulse bag filter most of the important parts (such as pulse valve, injection pipe, dust collector dimensions, etc.) detailed design calculations to determine the parameters and draw the dust drawings, determine filter models. In the design, combined with the knowledge learned on the materials, find relevant information and data. Cold-rolled steel in accordance with the actual situation, determine the amount of dust in the air handling and filtration velocity, according to national standards, through the purification of exhaust gas after the dust concentration in the control of 30mg / m3 or less. Calculated according to the design size, roughly drawn outline diagram for the filter installation.
