READ MOREThe fume treatment plant is mainly composed of upper box, middle box, ash hopper, air inlet equalizing pipe, support filter bag, injection device, ash unloading device, etc. The dusty gas enters the ash hopper of each compartment from the air inlet equalizing pipe of the dust collector, and under the guidance of the ash hopper guiding device, the dust of large particles is separated and directly falls into the ash hopper
READ MOREThe application and development of fume treatment plant technology are closely related to the process of industrialization in China. Dust removal technology generally includes mechanical dust removal, wet dust removal, electrostatic dust removal and bag dust removal.
