The invention relates to the field of removal of dust from gas mixtures (large, small and fine), in particular for removal of dust from air, and can be used in the systems of dust-gas cleaning at metallurgical, chemical and other works. A dust precipitation chamber comprises a housing (1), an inlet (2) for supply of dusty air, an outlet (6) for removal of purified air, a separation chamber and an unloading device. The separation chamber is made of separation sections (3) in the form of partitions (7), which are closely overlapping the section of dust precipitation chamber, and the partitions are equipped with vibrators (9) and are made in the form of double nets (8) with holes (a) and in the bottom are formed the channels () for passage of shaken dust, and the unloading device consists of unloading augers (4) of separator sections and a split screw (5) of the dust precipitation chamber, and the holes () of double nets (8) of previous separator sections (3) have an aerodynamic cross-section, which is larger than the aerodynamic section of the next separator sections, and the diameter of holes () Dof double nets is determined by the formula: D=d*(20÷35) mm, where d- transverse size of dust particles. The technical result of the present invention is increase the efficiency of the dust precipitation chamber. |
