How to select the size depend on bag house filtration velocity ?

1, According to the number of bags Obtaining a total filter area and the area of a single dust bag, the bag can be calculated number. If the number of bags each bag chamber is determined, whereby it can also calculate the number of the rooms throughout the bag house. Although the press need to determine the number of cells in the bag house design or selection, but the site layout and maintenance convenience, often room to room with more than six in addition to sitting on the set to double. The chamber 5 is less than the dust of the chambers as a single row. In addition to the selection of two or more parameters, dusty gas flow, nature, and the concentration of dust dispersion, wettability, viscosity and other parameters are selected filter bag house Winds size. Understanding these parameters, we can easily select the bag house filtration wind speed in order to improve the efficiency of the bag house, thereby reducing costs. 2, According to the different types of dust cleaning in different ways Carbon black, silicon oxide (silica), aluminum, zinc sublimate solution to other gas in the gas due to condensation and chemical reactions and the formation of activated carbon, the cement kiln exhaust. Filtration velocity in the 0.25 ~ 0.40.3 ~ 0.50.33 ~ 0.600.8 ~ 1.2 m / s. Iron and ferroalloys sublimate, foundry dust, alumina, cement mill discharged from the cement, carbide furnace Changhua matter, lime, alumina, plastic, iron oxides, coke, coal. Filtration velocity in the 0.28 ~ 0.450.4 ~ 0.650.45 ~ 1.01.0 ~ 2.0 m / s. Talc, coal, blast cleaning dust, fly ash, ceramic production of dust, carbon black (secondary processing), pigments, kaolin, limestone, mineral dust, bauxite, cement (from the cooler). Filtration velocity in the 0.30 ~ 500.50 ~ 1.00.6 ~ 1.21.5 ~ 3.0 m / s.
