The invention discloses a stacked cylinder type
flue lampblack electrostatic purification device which comprises an outer fixing cylinder and an inner
electrode adsorption cylinder. The outer fixing cylinder is in a conical shape with a narrow upper part and a wide lower part, the upper part and the lower part of the cylinder wall are provided with insulating devices, and the outer fixing cylinder is internally provided with at least two
electrode adsorption cylinders of which the diameters are sequentially decreased. The
electrode adsorption cylinders are stacked with the same circle center, the distances between the cylinder walls of the electrode adsorption cylinders are the same, discharging devices are arranged in the gaps of the electrode adsorption cylinders, irregular separators penetrating through the discharging devices are arranged in the gaps, and the upper and lower ends of the electrode adsorption cylinders and the
discharge devices are fixed with the insulation devices through the fixing devices. According to the present invention, the
straight electrode adsorption cylinders are changed into the conical electrode adsorption cylinders, and the
discharge devices parallel to the electrode adsorption cylinders are fixed in the gaps of the electrode adsorption cylinders, so that the
ionization range is wider, the lampblack adsorption capacity is improved, and an
electric arc phenomenon caused by
oil mist dripping of the straight cylinders is avoided.
