Dust bag skeleton ribs, it should be lightweight, easy to install and maintain a direct impact on the quality of the frame bag filter status and longevity. With natural granite, machined into a circular curved plate, the overall structure is smooth. There corrosion resistance, wear resistance, high temperature characteristics. external temperature high strength material pouring acid. cylinder steel outer protection equipment, greatly enhancing the strength and life of the equipment. body with every section of one meter structure, Each section has a convex-shaped seam at the interface, when installed in the slot connection furan resin or acid clay, to ensure watertight connections; overcoming the original granite dust seam seepage and leakage is a common problem with the upper ceramic sink. structure, ceramic water filter ensure watertight process, avoiding the frustration of the original granite dust tank seepage, and enhance the use of the effect of the precipitator installation simple, generally every section of one meter, on-site installation is complete lifting half a day to reduce the construction period
