Bag house is a dry dust filter device. Close it for trapping small, dry, non-fibrous dust. Filter bag is made using mats woven or non-woven cloth, the use of fabric filter dust gas filter effect, when the dusty gas entering the bag house dust skeleton, large particles, heavy dust, because the force of gravity settling down, falling into the hopper, finer dust containing gas through the filter, the dust is retained, the negative gas purification. It refers bag house air volume per unit time of the volume of gas that can be purified. Units of cubic meters per hour (m3 / h) or standard cubic meters per hour (Nm3 / h). Dust bag design is one of the most important factors. According to the amount of wind bag house designed or selected frame, generally can not run in the case of dust over the delimitation of the air volume, otherwise, the bag easily blocked, shortened life expectancy, a significant increase in the pressure loss, collection efficiency should be reduced; but they can not the selected air volume is too large, otherwise the increase in investment in equipment and floor space. Selection process fair amount of wind is often based on technology and experience to decide. Dust bag filter bag house dust skeleton is to determine the efficiency of the hub parts, the replacement bag of expense and maintenance costs are the main bag filter, so the filter bag life related to the operating state and capital . bag house dust bag is to determine the removal efficiency of the hub parts, the replacement bag of expense and maintenance costs are the main bag filter, so the filter bag life related to the operating state and capital. Dust collector bag is an effective dust filter – dust skeleton, can have good ventilation, dust, high efficiency, and a certain acid, alkali and heat capacity of the weaving process used in the multilateral brushed, progress fabric thickness, elastic, very good effect of dust, dust removal rate of 99.99%. Dust bag is taken polyester staple fiber as raw material, life is generally 4-6 times that of glass fiber fabric, good ventilation, dust collection rate, content cleaning, dust removal efficiency of up to 98.99.
