Pre-attached layer filtering techniques: the traditional baghouse it previously attached to a layer of dust layer (called pre-attached layer), a pre-attached layer material by adsorption, absorption and catalytic effects of industrial emissions of gas, Liquid pre-purification plant pollutant smoke skylights, and then the solid pollutants in the flue gas while removing technology. First, galvanized iron duct processing quality requirements: 1, that is sheet metal duct processing must comply with the requirements specification and design, and size of the duct must meet the design requirements, bite duct joints must be closely Hangzhou plant exhaust design, uniform width, no holes, semi-seams and bursting and other defects. 2, duct straight appearance, surface irregularities of not more than 5mm, wind pipe and flange connections are secure Hangzhou plant flue dust, cuffs flat. 3, product protection: Duct flange After processing plant shall be classified neatly stacked exhaust, open place measures should be taken to prevent rain and snow, attention flange corrosion and protect the zinc coating duct.
