Electrode screen board for radial-flow electric dust collector

Abstract

An electrode screen board for a radial-flow electric dust collector comprises a plurality of porous foam metal boards with board faces located in right and left vertical directions, wherein the side faces of the adjacent porous foam metal boards are mutually adhered; the porous foam metal boards are spliced into an electrode board (1) allowing air flowing through the board face; a mounting rack (2) is arranged at rear of the electrode board (1); the electrode board (1) is fixed on the mounting rack (2); the volume density of each porous foam metal board is 0.15-2g / cm<3>; the specific surface area of each porous foam metal board is 7.8*10<2>-1.5*10<8>m<2> / m<3>; the thickness of each porous foam metal board is 3-60mm; and the number of PPI (Pores Per Inch) of each porous foam metal board is 5-110. The invention aims at providing the electrode screen board for the radial-flow electric dust collector, which is great in treatment gas flow and long in service life, has high efficiency of removing dust with very fine particles, and can allow the absorbed dust to be capable of being smoothly removed from the porous foam metal boards.

Description

technical field [0001] The invention relates to an electrode grid plate for a radial flow electric dust collector. Background technique [0002] The anode of the radial-flow electrostatic precipitator is made of porous foam metal plate. The anode of the radial-flow electrostatic precipitator made of porous foam metal plate can absorb very fine dust particles, but how to scientifically set the radial-flow electrostatic precipitator Anode, to ensure that the radial flow electrostatic precipitator can always efficiently remove very fine particles of dust, the processing air flow must be large, and at the same time, the adsorbed dust must be smoothly removed from the porous foam metal plate, which involves To how to combine the performance parameters such as the thickness of the porous foam metal plate, the bulk density, the specific surface area of ​​the porous foam metal plate and the number of holes per inch (PPI) of the porous foam metal plate, but in this At present, there...
